RainWater Harvesting

N kavya

Rainwater harvesting is a sustainable process that helps in preserving water for future needs. Water scarcity is a major concern in today’s scenario. The process of rainwater harvesting is a good way to conserve water. Rainwater Harvesting is one of the most used methods to save water. It refers to storing rainwater for various uses. The notion behind rainwater harvesting is to not waste the rainwater and prevent it from running off. In other words, it is done to collect rainwater using simple mechanisms. It is usually collected at the place the rain falls from the ground or rooftops. Rainwater harvesting is an alternative to reduce the stress of public water supply sources. The recharge of rainwater to the ground in the coastal regions prevents seawater immersion into the freshwater. Finally, rainwater harvesting reduces water supply bills.

Rainwater Filtration -:

Rainwater can be harvested or purified in multiple ways. The catch area before harvesting must be cleaned thoroughly, and the pipelined must be flushed regularly. Initially, the water flow is diverted to wash or rinse the area.
Rainwater contains contaminants or other waste materials that affect the quality of the water. Contaminants such as dust, Bird excreta, pollution, leaves, and sand particles can affect water quality.

Filtration removes contaminants and other impurities and purifies rainwater for drinking and other purposes. However, the harvested water must be treated and tested before consumption to ensure the right quality check.
Industries use the practice of pre-filtration to ensure that the purified water is directed water to the tank. The pre-filtration measure is a vital step that the water supply system should not compromise in terms of water quality.

Some techniques of rainwater purification are solar sterilization, the use of chemicals like iodine or chlorine, or sediment filtration. However, harvested rainwater used for drinking purposes can be filtered through Reverse Osmosis (RO).

Favorable aspects of Rainwater Harvesting -:

Rainwater Harvesting positively affects underground water quality. It dilutes the number of nitrates, fluorides, and salinity of the underground water. It contains zero hardness and almost neutral pH, making it highly suitable for industries, homes, institutions, industries, and other commercial establishments. Rainwater Harvesting reduces water supply bills. It is an excellent method that solves the water shortage crisis and lessens the energy consumption in water disturbance. Rooftop Rainwater harvesting controls urban flooding. The recharge of rainwater to the ground in the coastal regions prevents seawater immersion into the freshwater. Rainwater harvesting is an alternative to reduce the stress of public water supply sources. Construction of deeper wells can damage the natural environment as well as upscale. Therefore, the source of rainwater is highly effective and dependable. Stored harvested rainwater can be used as an alternative to municipal water and used during the water crisis.

Rainwater harvesting can be done in a variety of methods, including -:

1. A watershed is a region where precipitation flows directly into a river or another reservoir.
2. There are two ways to keep water: on the roof or the ground.
3. Normally, rainwater is collected on the rooftops. The rainwater from the roof is usually collected in PVC pipes and stored in a sump (a deep pit dug into the earth) or a tank.
4. The water in the tank can then be used for home purposes after it has been filtered.
5. Rainwater collection also helps to restore natural aquifers.

The two types of rainwater harvesting -:

1. Surface runoff harvesting -:

In this method, rainwater flows away as surface runoff and can be stored for future use. Surface water can be stored by diverting the flow of small creeks and streams into reservoirs on the surface or underground. It can provide water for farming, cattle, and for general domestic use. Surface runoff harvesting is most suitable in urban areas.
Rooftop rainwater/storm runoff can be harvested in urban areas through:
• Recharge Pit
• Recharge Trench
• Tubewell
• Recharge Well

Groundwater recharge -:

Groundwater recharge is a hydrologic process where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. The aquifer also serves as a distribution system. The surplus rainwater can then be used to recharge Grothe underwater aquifer through artificial recharge techniques.

3. Rainwater in rural areas can be harvested through -:

• Gully Plug
• Contour Bund
• Dugwell Recharge
• Percolation Tank
• Check Dam/Cement Plug/Nala Bund
• Recharge Shaft

Although rainwater harvesting measure is deemed to be a desirable concept for the last few years, it is rarely implemented in rural India. Different regions of the country practiced a variety of rainwater harvesting and artificial recharge methods. Some ancient rainwater harvesting methods followed in India includes Madaras, Ahar Pynes, Surangas, Taankas, etc.

Advantages of Rainwater Harvesting -:

1. Less cost.
2. Helps in reducing the water bill.
3. Decreases the water demand.
4. Reduces the need for imported water.
5. Promotes both water and energy conservation.
6. Improves the quality and quantity of groundwater.
7. Does not require a filtration system for landscape irrigation.
8. This technology is simple and easy to install and operate.
9. It reduces soil erosion, stormwater runoff, flooding, and pollution of surface water with fertilizers, pesticides, metals, and other sediments.
10. It is an excellent source of water for landscape irrigation with no chemicals, or dissolved salts, and is free from all minerals.

Disadvantages of Rainwater Harvesting-:

1. In addition to the great advantages, the rainwater harvesting system has a few disadvantages like unpredictable rainfall, unavailability of the proper storage system, etc.
2. Listed below are a few more disadvantages of the rainwater harvesting process.
3. Regular maintenance is required.
4. Requires some technical skills for installation.
5. Limited and no rainfall can limit the supply of rainwater.
6. If not installed correctly, it may attract mosquitoes and other waterborne diseases. 7. One of the significant drawbacks of the rainwater harvesting system is storage limits.

The world faces an increasingly critical need to address climate change, and the impact that water conservation has on a sustainable environment is undeniable. Groundwater is the primary source of freshwater that caters to the demand of the ever-growing domestic, agrarian, and industrial sectors of the country. Over the years, it has been observed that the necessity for the exploitation of groundwater resources for various everyday needs, like toileting, bathing, cleaning, agriculture, drinking water, industrial and ever-changing lifestyles with modernization is leading to tremendous water wastage. Harvesting and collecting rainwater is an adequate strategy that can be used to address the problem of water crisis globally. The use of a rainwater harvesting system provides excellent merits for every community. This simple water conservation method can be a boost to an incredible solution in areas where there is enough rainfall but not enough supply of groundwater. It will not only provide the most sustainable and efficient means of water management but also unlock the vista of several other economic activities leading to the Empowerment of people at the grass-root level.

For this, the Government should come out with an appropriate incentive structure and logistic assistance to make it a real success. Rainwater harvesting is something that thousands of families across the world should participate in rather than pinning hopes on the administration to fight the water crisis. This water conservation method is a simple and effective process with numerous benefits that can be easily practiced in individual homes, apartments, parks, and across the world. As we all know that charity begins at home, likewise, a contribution to society’s welfare must be initiated from one’s home.

Solar Energy for The Future

N kavya

Solar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage.

The Process of Solar Energy –

This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy. At its core, the sun fuses about 620 million metric tons of hydrogen every second. The PP chain reaction occurs in other stars that are about the size of our sun and provides them with continuous energy and heat. The temperature for these stars is around 4 million degrees on the Kelvin scale (about 4 million degrees Celsius, 7 million degrees Fahrenheit).

In stars that are about 1.3 times bigger than the sun, the CNO cycle drives the creation of energy. The CNO cycle also converts hydrogen to helium but relies on carbon, nitrogen, and oxygen (C, N, and O) to do so. Currently, less than 2% of the sun’s energy is created by the CNO cycle.

Nuclear fusion by the PP chain reaction or CNO cycle releases tremendous amounts of energy in the form of waves and particles. Solar energy is constantly flowing away from the sun and throughout the solar system. Solar energy warms the Earth, causes wind and weather, and sustains plant and animal life.

The energy, heat, and light from the sun flow away in the form of electromagnetic radiation (EMR).

The electromagnetic spectrum exists as waves of different frequencies and wavelengths. The frequency of a wave represents how many times the wave repeats itself in a certain unit of time. Waves with very short wavelengths repeat themselves several times in a given unit of time, so they are high-frequency. In contrast, low-frequency waves have much longer wavelengths.

The vast majority of electromagnetic waves are invisible to us. The most high-frequency waves emitted by the sun are gamma rays, X-rays, and ultraviolet radiation (UV rays). The most harmful UV rays are almost completely absorbed by Earth’s atmosphere. Less potent UV rays travel through the atmosphere and can cause sunburn.

The sun also emits infrared radiation, whose waves are much lower frequency. Most heat from the sun arrives as infrared energy.

Sandwiched between infrared and UV is the visible spectrum, which contains all the colors we see on Earth. The color red has the longest wavelengths (closest to infrared), and violet (closest to UV) the shortest.

Natural Solar Energy

1. Greenhouse Effect
2. Photosynthesis
3. Fossil Fuels
• Harnessing solar Energy (The methods use either active solar energy or passive solar energy)
• Photovoltaics
• Concentrated solar energy
• Solar Architecture

Advantages & Disadvantages of Solar Energy

1. Advantages
• Solar energy is clean. After the solar technology equipment is constructed and put in place, solar energy does not need fuel to work. It also does not emit greenhouse gases or toxic materials.
• There are locations where solar energy is practical. Homes and buildings in areas with high amounts of sunlight and low cloud cover have the opportunity to harness the sun’s abundant energy.
• Solar energy complements other renewable sources of energy, such as wind or hydroelectric energy.

Homes or businesses that install successful solar panels can produce excess electricity. These homeowners or business owners can sell energy back to the electric provider, reducing or even eliminating power bills.

2. Disadvantages
• Solar energy equipment is also heavy. To retrofit or install solar panels on the roof of a building, the roof must be strong, large, and oriented toward the sun’s path.
• Both active and passive solar technology depends on factors that are out of our control, such as climate and cloud cover. Local areas must be studied to determine whether or not solar power would be effective in that area.
• Sunlight must be abundant and consistent for solar energy to be an efficient choice. In most places on Earth, sunlight’s variability makes it difficult to implement as the only source of energy.

DREAM ON…..

N kavya

Dream is a succession of images, ideas, emotions, and sensations that usually occur involuntarily in the mind during certain stages of sleep.

The content and function of dreams have been topics of scientific, philosophical, and religious interest throughout recorded history. Dream interpretation was practiced by the Babylonians in the third millennium BCE and even earlier by the ancient Sumerians. .Dreams figure prominently in major world religions. The dream experience for early humans, according to one interpretation, gave rise to the notion of a human ‘soul’ as a central element in much religious thought.

Psychologist Calvin S. Hall considered dreams part of the cognition process or a type of thinking that happens as you sleep. Hall believed dreams could offer important insight into how you view yourself and others, your problems and conflicts, and the world in general. Many psychologists believed dreams played an important role in cognitive processes including memory and emotion regulation. Domhoff also noted that, although dreams may shed some light on heavy concerns, they might not have any real purpose, because he stated normally human beings forget most of their dreams. William Dement, who helped found the field of sleep medicine, suggested that, while dreams may lack a clear purpose, they can still convey meaningful messages.

Many experts do not believe dreams have much meaning but believe they still serve a purpose. The existing theories outline a few of these purposes.

1. Threat simulation theory
2. Activation-Synthesis theory
3. Dreams as emotional regulation
4. Continual-activation theory

Psychotherapist, Eliza Boquin, states “For vivid dreamers, our body can often experience what is happening in the dream.”
Certified dream analyst and speaker Lauri Loewenberg says while you are sleeping your brain is conjuring up around five dreams per night. That is a lot of subconscious thoughts to unpack. And although every dream is unique, they do tend to follow certain symbolic patterns.

How to examine your own dreams -:

1. Make sure you are getting proper sleep –: Research says that if we get enough sleep (7 to 9 hours) each night. This may, in turn, boost dream recall.

2. Review the dream –: when you wake up from the dream, lie calmly and analyze the visions, emotions, people, and places and mainly pay attention to small details because it would play a significant role in examining the dream.

3. Write it down –: Have a journal and start writing what all you saw the colors and visions, also your moods and feelings.

4. Make connections to your own life -: connecting these facts to your everyday life, would connect to your past life experiences and in some cases might even show some glimpses of your future. There are also many dreams interpretation books that you can interpret and gain more insights into.

Dreaming and sleep are intertwined. Dreams occur mainly in the rapid-eye movement (REM) stage of sleep when brain activity is high and resembles that of being awake. No one knows for certain what purposes dream serve. But at the end of the day, their true function might not really matter. It depends on each individual If you find them meaningful, then they add value to you or do not concern you.

Nanotechnology

Nanotechnology is defined as fabrication of devices with atomic or molecular scale precision. Devices with minimum feature sizes less than 100 nanometers (nm) are considered to be products of nanotechnology. A nanometer is one billionth of a meter (10-9 m) and is the unit of length that is generally most appropriate for describing the size of single molecules.The nanoscale marks the nebulous boundary between the classical and quantum mechanical worlds; thus, realization of nanotechnology promises to bring revolutionary capabilities. Fabrication of nanomachines, nanoelectronics and other nanodevices will undoubtedly solve an enormous amount of the problems faced by mankind today.Nanotechnology is currently in a very infantile stage. However, we now have the ability to organize matter on the atomic scale and there are already numerous products available as a direct result of our rapidly increasing ability to fabricate and characterize feature sizes less than 100 nm. Mirrors that don’t fog, biomimetic paint with a contact angle near 180°, gene chips and fat soluble vitamins in aqueous beverages are some of the first manifestations of nanotechnology. However, immenant breakthroughs in computer science and medicine will be where the real potential of nanotechnology will first be achieved.

Nanoscience is an interdisciplinary field that seeks to bring about mature nanotechnology. Focusing on the nanoscale intersection of fields such as physics, biology, engineering, chemistry, computer science and more, nanoscience is rapidly expanding. Nanotechnology centers are popping up around the world as more funding is provided and nanotechnology market share increases. The rapid progress is apparent by the increasing appearance of the prefix “nano” in scientific journals and the news. Thus, as we increase our ability to fabricate computer chips with smaller features and improve our ability to cure disease at the molecular level, nanotechnology is herestorage (or other uses) is enormous. As first described in a lecture titled, ‘There’s Plenty of Room at the Bottom’ in 1959 by Richard P. Feynman, there is nothing besides our clumsy size that keeps us from using this space. In his time, it was not possible for us to manipulate single atoms or molecules because they were far too small for our tools. Thus, his
speech was completely theoretical and seemingly fantastic. He described how the laws of physics do not limit our ability to manipulate single atoms and molecules. Instead, it was our lack of the appropriate methods for doing so. However, he correctly predicted that the time would come in which atomically precise manipulation of matter would inevitably arrive.Nanomachines can also be incorporated into various materials to make those materials respond to their environment, or to outside commands. Examples of such materials would be “smart” fabrics that respond to the environment to become warmer or cooler, or walls and furniture that can move or change shape on command. Nanomachines could also be used as tools both in industry and by consumers. Such tools could cut apart or glue together material far more efficiently than anything large-scale that is used today. Nanomachines could also repair cars, furniture, applicances, or almost anything else quickly and efficiently. Or these objects could be designed with nanomachines to repair themselves should the need arise. Life would be greatly simplified by relieving people of the need to repair objects at home or at work.

In thinking about nanotecnolog today, what’s most important is understanding where it leads, what nanotechnology will look like after we reach the assembler breakthrough.
-Eric Drexler

Agriculture

The word “Agriculture” has no rigid definition. It has been explained by many people very comprehensively. Agriculture has been defined as the science and art of cultivating the soil, and this definition emphasizes the primary nature of plant production in agriculture.Moreover, it is so frequent that the same person performs both the primary functions of growing plants and the secondary one of feeding the plants to livestock that these two industries are grouped together as agriculture. Therefore, it may be said that agriculture includes not only the production of crops by the cultivation of the soil, but also the rearing of livestock.
Thus, milk, meat and wool are as much agricultural products as are wheat, rice and cotton. In the words of George O’Brien, therefore, the word agriculture includes, “every industry which aims at producing vegetables or animals by the cultivation of the soil.”So, agriculture is the business of raising products from the land. The products raised may either be plants and their products or animals and their products. The former are the direct products while the latter are the indirect products of the land. Agricultural products are complex and diverse, in nature, and as such, agriculture may be regarded as complex industry.Modern agriculture is such broader in scope than merely the art and science of cultivating the land. It is the whole business of supplying food and fiber for a growing population at home and abroad. Again in agriculture we include all forms of soil production, from forestry to glass-house culture, from fishery to artificial insemination, and from breeding to horticulture.

Primitive men must have begun as food gatherers, eating whatever fruits, leaves and roots they could obtain. Nature must have been bountiful in those days when human numbers were so small and wild plants grew everywhere. As time passed and human numbers grew, fishing and hunting became increasingly important in supplementing what was lacking in the field, and an endless search for food ensued.It was soon realized that some form of food production was necessary if men were to live long and secure. Animals were tamed, first to provide meat, milk and skin; later for use as draught animals. Seeds were sown in ploughed fields, carefully tended and harvested when the time came.Men were then able to live in settled communities. Because they were no longer continually moving they had time to develop the various arts, crafts and skills that formed the basis of modern industries and also evolved religious and political ideas. Without a settled agriculture, a measurable degree of civilization is not possible.

Agriculture
is not farming
it’s feeding

Disaster management

Disaster is a very common phenomenon to the human society. It has been experienced by them since time immemorial. Though its form may be varied, it has been a challenge for society across castes, creeds, communities and countries. The latest development which has been discovered in the World Disaster Reports recently is that the disasters have increased in frequency and intensity.People are becoming more and more vulnerable to disasters of all types, including earthquake, flood, cyclones, landslides, droughts, accidents, plane crash, forests fire, etc. With the technological advancements and progress, the force of disasters is also changing. When they occur they surpass all preparedness and eagerness of society and pose bigger challenge to them. This is quite true in case of both developed and developing countries. The floods in UK, France, and heat wave in Europe, particularly in France in 2003, claimed more than 35000 lives. In the year 2006, America had to face bigger disaster in the form of tornadoes and other cyclones. They caused great loss of lives and property. All these are sufficient to prove that technological mechanisms are inadequate.There is a direct correlation between higher human development and higher preparedness. The countries which have lesser human development are more vulnerable to risks of disasters and damage. Of all the disasters, floods are the most common followed by wind storms, droughts and earthquakes. But the drought is the deadliest disaster which accounts for 48 per cent of all deaths from natural disasters. The highest numbers of people die from disasters in Asia. India, China and Bangladesh are the worst affected countries by flood. Besides the natural disasters, transport accidents and technological disasters are also faced by the developing countries.

The UNDA with Government of India has jointly prepared an action plan for cities and towns vulnerable to earthquakes. The need in the vulnerable zones is that the existing buildings be technically assessed and evaluated and individual owners and group housing authorities should be informed about the weaknesses in their construction. Presently, in India, it is estimated that around 10 lakhs buildings which are constructed every year, an equal number of them get damaged as a result of disasters. It is required that a monitoring mechanism should be set up in disaster prone areas and it must act in proper coordination with the concerned to ensure fulfillment of building codes.
Disaster is a state subject in India; it is, therefore, the responsibility of the state to provide every kind of support and assistance to the victim. The Central Government has a facilitating role. It, with proper coordination with various ministries, extends all required support and helps to the states, namely defence services, air dropping, rescuing, searching, transport of relief goods, availability of rail and ferry services, health personnel and medical support, etc. In the State, the Relief Commissioner or Disaster Management Secretary is the specific authority responsible for handling and management of the disaster.

Rehabilitation is an integral part of disaster management. When disasters occur administrative measures are terribly inadequate and perhaps this is the most difficult period for a victim. The role of administration does not end with end of disasters. In fact its effort and commitment get more complex. It requires proper coordination among various agencies. In this context it is very important to note that disasters are non-routine events that require non-routine response. Government cannot rely on normal procedures to implement appropriate responses- the rescue teams require learning special skills, technologies and attitudes in dealing with disasters.

SUCCESSFUL EMERGENCY MANAGEMENT RELIES UPON EXPERIENCE AND EXPERTISE.

Pharmacology

Pharmacology is the science that deals with drugs.Pharmacology consists of detailed study of drugs, particularly drugs action on living animals, tissues or organs. The action of drugs may be beneficial or harmful.Pharmacology is the science in which we study the response of living animals to chemicals drug Pharmacology is defined as the study of the effects of drugs on the structures and metabolism of natural tissues.Pharmacology can be defined as the study of the manner in which the functions of living system is affected or influenced by chemicals.This subject deals with the properties and effects of drugs and in broad sense, it can be defined as the study of interactions between chemical substances and biological systems.While defining in broad sense, it includes the knowledge of the history, source, physical and chemical properties, compounding, bio-chemical and physiological effects, mechanism of action, absorption, distribution, metabolism, excretion and therapeutic and other effects of drugs.

Diseases are as old as man. Fighting disease with drugs is an endless task that originated from existence of mankind. Drugs have its origin with illness and the later has been associated with evolution. Just imagine about the nomads, the primitive man, who was wanderer, a food gatherer and shelter seeking. There was no concept of family.There were no clothes, men and women were wandering naked. Gradually the notion of family started and he lived together with so called his family members. If any of them died the pain of death he might have felt. He must have thought about death. Why some person dies? And then fear of death might have occurred to him. He must have started thinking about death.Homosapiens being the intelligent most among the species evolved, based on the principles of “necessity” and “trial” could observe effectiveness of many plants in relief for his pains and sufferings. The primitive (early) history of the causative agents of diseases included wrong Gods, spirits witches and other evil influences.
The form of therapy was incantation, prayer and ceremony designed to appease the evil agents of the diseases. They were using sacrifice of animals, individuals and prayers.The tribal leaders were known as medicine men or the expert or witch doctors (Ojha), were very powerful men and leader in such all ceremonies. In addition, they had knowledge about certain plants and animal products to be used in the treatment of certain diseases. The first treatise on medicine was undoubtedly the Ayurveda in India and that is at least 500 years ahead of the Greek Medicine.The medical literature was related to metaphysics, hypnotism etc. and belief in supernatural agencies as the cause and cure of diseases. Thus, in India, this was originally a part of the fourth Veda called the Atharva Veda. The real father of Indian Medicine was Atrya with his distinguished disciples-Agnivesha, Bhala, Jatukarana, parasara, Harita and Ksharapani.

Started with Oswald Schmiedeberg (1838-1921). He was excellent teacher of Pharmacology and attracted many persons to study this subject. Like other experimental sciences, Pharmacology, too, is highly dependent upon development in other branches of science.Spectacular developments in physiology, biochemistry, organic chemistry and molecular biology have greatly contributed in advancement of pharmacology. Conversion of the old pharmacology into modern pharmacology is fairly recent and probably started taking shape following introduction of experimental procedures in animals by Francois Megendie (1783-1855) and Claude Bernard (1813-1978).Oswald Schmiedeberg (1838-1921) introduced the technique of per-fusing isolated organs and study the effects of drugs on them. Abel, Cushny, Gottlieb and a galaxy of his other students popularized the expertise in their respective, countries. Thus Oswald become popular as ‘Father of modern Pharmacology’.

Pharmacology is benefited by the prepared mind. You need to know what you are looking for.

Horticulture

The science and art of growing, producing, marketing, and utilizing high-value, intensively grown food, and ornamental plants in a sustainable manner is known as Horticulture.Annual and perennial plants, fruits and vegetables, decorative indoor plants, and landscape plants are all examples of horticulture crops.

Horticulture farming also aims to enhance the quality of life, as well as the beauty, sustainability, and recovery of our ecosystem and the human condition.
Horticulture is divided into the cultivation of plants for food (pomology and olericulture) and plants for ornament (floriculture and landscape horticulture). Pomology deals with fruit and nut crops. Olericulture deals with herbaceous plants for the kitchen, including, for example, carrots (edible root), asparagus (edible stem), lettuce (edible leaf), cauliflower (edible flower buds), tomatoes (edible fruit), and peas (edible seed). Floriculture deals with the production of flowers and ornamental plants; generally, cut flowers, pot plants, and greenery. Landscape horticulture is a broad category that includes plants for the landscape, including lawn turf but particularly nursery crops such as shrubs, trees, and vines.

Temperate zones for horticulture cannot be defined exactly by lines of latitude or longitude but are usually regarded as including those areas where frost in winter occurs, even though rarely. Thus, most parts of Europe, North America, and northern Asia are included, though some parts of the United States, such as southern Florida, are considered subtropical. A few parts of the north coast of the Mediterranean and the Mediterranean islands are also subtropical. In the Southern Hemisphere, practically all of New Zealand, a few parts of Australia, and the southern part of South America have temperate climates. For horticultural purposes altitude is also a factor; the lower slopes of great mountain ranges, such as the Himalayas and the Andes, are included. Thus, the temperate zones are very wide and the range of plants that can be grown in them is enormous, probably greater than in either the subtropical or tropical zones. In the temperate zones are the great coniferous and deciduous forests: pine, spruce, fir, most of the cypresses, the deciduous oaks (but excluding many of the evergreen ones), ash, birch, and linden.

There is no sharp line of demarcation between the tropics and the subtropics. Just as many tropical plants can be cultivated in the subtropics, so also many subtropical and even temperate plants can be grown satisfactorily in the tropics. Elevation is a determining factor. For example, the scarlet runner bean, a common plant in temperate regions, grows, flowers, and develops pods normally on the high slopes of Mount Meru in Africa near the Equator, but it will not set pods in Hong Kong, a subtropical situation a little south of the Tropic of Cancer but at a low elevation.In addition to elevation, another determinant is the annual distribution of rainfall. Plants that grow and flower in the monsoon areas, as in India, will not succeed where the climate is uniformly wet, as in Bougainville in the Solomon Islands. Another factor is the length of day, the number of hours the Sun is above the horizon; some plants flower only if the day is long, but others make their growth during the long days and flower when the day is short. Certain strains of the cosmos plant are so sensitive to light that where the day is always about 12 hours, as near the Equator, they flower when only a few inches high; if grown near the Tropic of Cancer or the Tropic of Capricorn, they attain a height of several feet, if the seeds are sown in the spring, before flowering in the short days of autumn and winter. Poinsettia is a short-day plant that may be seen in flower in Singapore on any day of the year, while in Trinidad it is a blaze of glory only in late December.

The glory of gardening: hands in the dirt, head in the sun, heart with nature.

To nurture a garden is to feed not just on the body, but the soul.

Plato and his allegory of the cave.

Plato was born in Athens, Greece, around 429 B.C. He was expected to become a politician by his family but he chose not to for two reasons and took the road of philosophy and mathematics. The first reason was the Peloponnesian War where he found out that some of his relatives were part of a dictatorship and were removed for corruption. The second reason was the death of Socrates who was the biggest influence in Plato’s life. Socrates was executed by the new Athenian government. Plato started writing and became a philosopher. He studied under Pythagoras in Sicily. After returning from there, he founded The Academy, a place where he and other people discussed philosophy and mathematics to come to better conclusions.

Plato’s allegory of the cave proves the power of reasoning over the senses. Personal human experiences will not amount to the truth. Proper philosophical reasoning is the only way to find the truth. To understand his allegory of the cave, you first need to understand his theory of forms. So Plato states that reality exists on two specific levels. First is the visible world which has sight and sound. Second is the intelligible world which gives the visible world its being. For example, when a person sees an ugly face he’s quickly able to identify its ugliness of it. Because in his mind he has an idea of ugly that allows him to point out ugly. He was able to spot the ugliness because he has an abstract idea of what ugliness is. The current state of that ugly face might change in the future because everything keeps changing in the visible world but the form of beauty, ugly etc is eternal and never changes. This is the theory of forms.

Coming onto the theory of caves, The allegory of caves was a conversation between Socrates and Plato’s brother, Glaucon. Socrates asks Glaucon to imagine a world where illusion is believed to be reality. To prove his point further, he asks him to imagine a scenario where there’s a cave and 3 people are locked up inside the cave since their birth. Their necks and legs are chained and cannot escape from the cave. They can only see what is in front of them. Behind and above the prisoners is a fire, and between the fire and prisoners, there is a low wall from where people walk with objects in their heads. Now, these prisoners can only see the shadow of the object and therefore they believe the shadow to be the real form of the object. Because the prisoners have never been exposed to real objects, they start to believe that the real form of that object looks like a shadow. If a shadow of a hammer were to appear, they’d believe the shadow of the hammer to be the real hammer. They are not saying that it’s a shadow because in their reality no shadows exist. They think it’s an actual hammer. One of the prisoners will eventually be able to understand the nature of this illusionary world and would be able to guess what shadow will come next. This will lead to him being praised by the other 2 prisoners.

Suppose, one of the prisoners is set free. He escapes the cave and gets to see the world. He gets angry and frustrated after seeing the real world because he believes the cave illusion to be his reality. When his reality is disproved, he becomes angry, sad and frustrated because he is now forced to believe something else and step out of his comfort zone. Eventually, he’ll be able to make sense of what he has seen and accept that the cave illusion was not his reality. He has now accepted that his past was based on a lie and that is not the way he should perceive things going ahead because he has now found out that it was all an illusion. He goes back to the cave to tell the other prisoners about the real world. When he tells them whatever he has witnessed, they don’t believe him and threaten to kill him if he tries to free them. They are so comfortable in their fake reality that they don’t even want to make the effort of exploring a new possibility because that might lead them out of their comfort zone and face chaos. People mistake what is in front of them as reality and choose to live in ignorance. And when parts of the truth start to emerge in front of their eyes, they get frightened. Because that threatens their ignorant reality. However, a person who pays attention to these flashes of truth and is open to the idea of exploration will always have a better understanding of the world around him. Always aim for reasoning rather than simply believing what seems easy to believe.

Science and Technology- developments and their applications and effects in everyday life.

Science and technology are widely recognized as important tool to promote and enhance the country’s socio-economic development. India has made considerable progress in various fields of science and technology over the years and can now boast of having a strong network of Science & Technology institutions, skilled manpower and infrastructure. innovative knowledge. Given the rapid pace of globalization, the rapid depletion of raw materials, the increasing competition between countries and the growing need for intellectual property protection, the importance of strengthening the knowledge base becomes even more important. Agenda is to enhance application-oriented research and development to create technology; promote human resource development, including encouraging bright students to pursue scientific careers; encouraging research and application of science and technology for forecasting, prevention and mitigation of natural disasters; integrate the development of science and technology into all areas of national activities; and exploiting science and technology to improve livelihoods and create jobs; environmental protection and ecological security. Science and technology is of great importance for economic growth at the macro level and for enhancing the competitiveness of enterprises at the micro level. Globalization and liberalization have created great opportunities and some challenges for Science and technology.

DEVELOPMENTS

In India, the role of science and technology in national development has been recognized by the government. The second five-year plan emphasizes that “the most important factor to promote economic development is the will of the community to apply modern science and technology”. In 1971, the Department of Science and Technology (DST) was established to promote new fields of science and technology. Similarly, State Councils of Science and Technology have also been established at the state level. As part of national policy, the government promotes various research and development programs to encourage scientific activities. Thus, we see that modern scientific and technological knowledge has had an impact on almost all fields such as agriculture, industry, nuclear energy, space technology, electronics, medicine and science. Development of Health Sciences. In addition to these key areas, India has also made progress in several other areas. These include the activities of the Petroleum and Natural Gas Commission in oil exploration and refining and the National Environmental Planning Commission in environmental protection and solar power generation. A Central Ganges Administration has been established to control Ganga pollution using wastewater treatment plants, etc. Currently, the country has a solid foundation in modern technology. It also has the third largest science and engineering workforce in the world. India has become a major destination for outsourced R&D activities. We currently have more than 1,100 R&D centers established by multinational enterprises (MNCs) such as IBM, Google, Microsoft, Intel, Lupin, Wockhardt, etc. These R&D centers cover areas such as information and communication technology, biotechnology, aerospace, automotive, chemical and materials technology. India’s relatively strong intellectual property regime will enable the country to emerge as a major R&D hub. Indian scientists are at the forefront of some of the world’s ground-breaking works. Recent contributions by Indian scientists to cutting-edge research and technology have been encouraging. For example, 37 Indian scientists from 9 Indian institutions who played a key role in the discovery of gravitational waves received the 2017 Nobel Prize in Physics. Indian scientists also contributed. on the discovery of neutron star mergers at the Laser Interferometer Gravitational-Wave Observatory (LIGO), USA. The development of Brahmos, advanced supersonic anti-aircraft interceptors, various types of missiles and missile systems, remote control vehicles, light combat aircraft, etc. are examples. highlights India’s advances in strategic and defense technology. India currently ranks among the few countries with reliable space technology capabilities. The upgrade of SLV to ASLV and PSLV to GSLV, the first lunar orbiter project Chandrayan-1, the Mars Orbiter Mission and the recent simultaneous launch of 104 satellites are remarkable achievements of India. India is currently the third largest country in terms of number of startups. This number is predicted to grow exponentially in the coming years. The government has established the Atal Innovation Mission (AIM) to completely transform the country’s innovation, entrepreneurship and startup ecosystem.

Applications and Effects in Everyday Life

Science and technology affect us all, every day of the year, as soon as we wake up, day and night. Our digital alarm clocks, the weather, the vehicles we drive, the buses we take, our decision to eat a baked potato instead of fries, our cell phones. me, antibiotics for your sore throat, clean water and all the lights have brought us the contributions of science. It affects socialization and productivity. The power of the Internet has made it easier for global communities to form and share ideas and resources. The modern world would not be modern at all without the knowledge and technology created by science. The influence of science on people’s lives is growing. Although the recent benefits to humanity are unprecedented in human history, in some cases harmful or long-term effects raise serious concerns. Today, the public distrust of science and fear of technology is a significant metric. This is partly due to the belief of some individuals and communities that they will be the ones to bear the indirect negative consequences of technical innovations introduced for the benefit of a special minority. permission. The power of science to bring about change forces scientists to proceed with caution in what they do and what they say. Scientists should reflect on the social consequences of technology applications or partial disclosures about their work and explain to the public and policymakers the degree of uncertainty. or the scientific incompleteness of their findings. At the same time, however, the exploitation of the full predictive power of qualified science should not be avoided to help humans cope with environmental change, especially in the face of direct threats such as natural disasters. or water shortage. Science and Technology offers simple and affordable science-based solutions that help individuals save time, energy and increase income. Technology adds value to handicraft products, playing an important role in enhancing their competitiveness. In general, S&T can play an important role in extending informatics to the most remote areas of the country by emphasizing computer literacy, making it accessible to those without formal education. Information Technology. Thus, “problem populations” can be transformed into valuable “human resources” through activity-oriented training and skill upgrading, which develop entrepreneurship and facilitate for independent employment through the use of new technologies. S&T provides solutions to long-term problems such as drought, disease, lack of domestic water, nutrition, sanitation, health, housing, etc. and other everyday issues, including the transition to unconventional energy sources and product packaging. Knowledge of science and technology helps to find ways for people to have the habit of using natural resources more wisely such as wood, bamboo, medicinal plants, etc. through the application of environmentally friendly technologies.

International Day Of Yoga

2021 Theme: Yoga for well-being
The Day will be marked at a time when COVID-19 pandemic continues to upend lives and livelihoods of people globally.

Beyond its immediate impact on physical health, the COVID-19 pandemic has also exacerbated psychological suffering and mental health problems, including depression and anxiety, as pandemic-related restrictions continue in various forms in many countries. This has highlighted the urgent need to address the mental health dimension of the pandemic, in addition to the physical health aspects.

The message of Yoga in promoting both the physical and mental well-being of humanity has never been more relevant. A growing trend of people around the world embracing Yoga to stay healthy and rejuvenated and to fight social isolation and depression has been witnessed during the pandemic. Yoga is also playing a significant role in the psycho-social care and rehabilitation of COVID-19 patients in quarantine and isolation. It is particularly helpful in allaying their fears and anxiety.

Recognizing this important role of Yoga, this year’s commemoration of the International Day of Yoga focuses on “Yoga for well-being” – how the practice of Yoga can promote the holistic health of every individual.

The United Nations offers yoga resources to its personnel and others on the COVID-19 portal’s section on Wellness.

The World Health Organization mentions yoga as a means to improve health in its Global action plan on physical activity 2018–2030: more active people for a healthier world.

UNICEF says kids can practice many yoga poses without any risk and get the same benefits that adults do. These benefits include increased flexibility and fitness, mindfulness and relaxation.

2021 virtual event
The Permanent Mission of India to the United Nations invites you to an online celebration of the 7th annual International Yoga Day on 21 June 2021, from 8:30 to 10:00 am EST, broadcast live on UN WebTV.

The event opened with messages from the President of the United Nations General Assembly and the Deputy Secretary-General of the United Nations, which was followed by demonstrations of Yoga exercises (asanas) to improve physical, mental, emotional and spiritual health and an interactive panel discussion on “Yoga for well-being.”

What is Yoga and why do we celebrate it?
Yoga is an ancient physical, mental and spiritual practice that originated in India. The word ‘yoga’ derives from Sanskrit and means to join or to unite, symbolizing the union of body and consciousness.

Today it is practiced in various forms around the world and continues to grow in popularity.

Recognizing its universal appeal, on 11 December 2014, the United Nations proclaimed 21 June as the International Day of Yoga by resolution 69/131.

The International Day of Yoga aims to raise awareness worldwide of the many benefits of practicing yoga.

The draft resolution establishing the International Day of Yoga was proposed by India and endorsed by a record 175 member states. The proposal was first introduced by Prime Minister Narendra Modi in his address during the opening of the 69th session of the General Assembly, in which he said: “Yoga is an invaluable gift from our ancient tradition. Yoga embodies unity of mind and body, thought and action … a holistic approach [that] is valuable to our health and our well-being. Yoga is not just about exercise; it is a way to discover the sense of oneness with yourself, the world and the nature.”

The resolution notes “the importance of individuals and populations making healthier choices and following lifestyle patterns that foster good health.” In this regard, the World Health Organization has also urged its member states to help their citizens reduce physical inactivity, which is among the top ten leading causes of death worldwide, and a key risk factor for non-communicable diseases, such as cardiovascular diseases, cancer and diabetes.

But yoga is more than a physical activity. In the words of one of its most famous practitioners, the late B. K. S. Iyengar, “Yoga cultivates the ways of maintaining a balanced attitude in day-to-day life and endows skill in the performance of one’s actions.”

Plastic Waste Management

Introduction

Plastic waste management is a collective term for various approaches and strategies used to recycle plastic materials that would otherwise be dumped into landfills, or bodies of water, or otherwise contaminate the environment. The idea behind this type of waste management is to utilize those discarded materials to manufacture new plastic products without the need to actually generate additional plastic materials. Doing so can help lower production costs as well as protect the environment.

Many different types of industries participate in some type of plastic waste management process. Some are specifically geared toward collecting plastic items for recycling. For example, many supermarkets encourage customers to contribute unwanted plastic bags into a recycling container located near the front of the store. The collected bags are then forwarded to recycling centres where the material is processed for use in the production of new products made from the recycled plastic.

Businesses that produce plastic products also engage in the task of plastic waste management. This often focuses on finding ways to recycle or reuse excess plastic that is discarded as units of different goods are produced. These plastic remnants can often be collected and ran through an internal recycling process to create additional products for sale. Not only does this approach prevent the disposal of the used materials into a landfill, it also allows the company to lower the actual cost associated with manufacturing each unit of its product line.

In some cases, businesses outsource the process of plastic waste management. Contracting with a waste management company makes it possible for unwanted plastic items to be collected and removed from the premises without expending additional company resources. Municipalities sometimes work with a waste management disposal company in creating plastic recycling programs that allow households to conveniently dispose of plastic milk jugs, broken plastic toys, and other plastic items without placing them into the trash. Depending on the nature of the arrangement with the plastic waste management company, the municipality may actually earn a small amount from the arrangement, creating another stream of revenue for the city or town that can be used to fund services offered to residents.

Any type of plastic waste management must be conducted in compliance with regulations set by local, state, and federal governments. This includes using recycling methods that are considered to be environmentally friendly, and that are not likely to create health risks for individuals living and working in the community. Since regulations regarding recycling vary somewhat from one jurisdiction to another, it is important to determine what is and is not allowed before establishing any type of ongoing program to deal with plastic waste.

Climate Change

Climate change is a long-term shift in global or regional climate patterns. Often climate change refers specifically to the rise in global temperatures from the mid-20th century to present.

Climate is sometimes mistaken for weather. But climate is different from weather because it is measured over a long period of time, whereas weather can change from day to day, or from year to year. The climate of an area includes seasonal temperature and rainfall averages, and wind patterns. Different places have different climates. A desert, for example, is referred to as an arid climate because little water falls, as rain or snow, during the year. Other types of climate include tropical climates, which are hot and humid, and temperate climates, which have warm summers and cooler winters.

Climate change is the long-term alteration of temperature and typical weather patterns in a place. Climate change could refer to a particular location or the planet as a whole. Climate change may cause weather patterns to be less predictable. These unexpected weather patterns can make it difficult to maintain and grow crops in regions that rely on farming because expected temperature and rainfall levels can no longer be relied on. Climate change has also been connected with other damaging weather events such as more frequent and more intense hurricanes, floods, downpours, and winter storms.

In polar regions, the warming global temperatures associated with climate change have meant ice sheets and glaciers are melting at an accelerated rate from season to season. This contributes to sea levels rising in different regions of the planet. Together with expanding ocean waters due to rising temperatures, the resulting rise in sea level has begun to damage coastlines as a result of increased flooding and erosion.

The cause of current climate change is largely human activity, like burning fossil fuels, like natural gas, oil, and coal. Burning these materials releases what are called greenhouse gases into Earth’ atmosphere. There, these gases trap heat from the sun’s rays inside the atmosphere causing Earth’s average temperature to rise. This rise in the planet’s temperature is called global warming. The warming of the planet impacts local and regional climates. Throughout Earth’s history, climate has continually changed. When occurring naturally, this is a slow process that has taken place over hundreds and thousands of years. The human influenced climate change that is happening now is occurring at a much faster rate.

Climate change is impacting human lives and health in a variety of ways. It threatens the essential ingredients of good health – clean air, safe drinking water, nutritious food supply, and safe shelter – and has the potential to undermine decades of progress in global health. Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress alone. The direct damage costs to health is estimated to be between USD 2-4 billion per year by 2030. Areas with weak health infrastructure – mostly in developing countries – will be the least able to cope without assistance to prepare and respond. WHO supports countries in building climate-resilient health systems and tracking national progress in protecting health from climate change. Reducing emissions of greenhouse gases through better transport, food and energy-use choices results in improved health, particularly through reduced air pollution. The Paris Agreement on climate change is therefore potentially the strongest health agreement of this century. WHO supports countries in assessing the health gains that would result from the implementation of the existing Nationally Determined Contributions to the Paris Agreement, and the potential for larger gains from more ambitious climate action.

The Upper Paleolithic World

Introduction

After about 40,000 years ago, we see many significant changes in the archaeological record, reflecting important changes in cultural and social life. We see art, many new inventions, and considerable increases in the population. This period of cultural history in Europe, the Near East, and Asia is known as the Upper Paleolithic and dates from about 40,000 years ago to the period known as the Neolithic (beginning about 10,000 years ago, depending on the area). In Africa, the cultural period comparable to the Upper Paleolithic is known as the Later Stone Age and many have begun much earlier.

In many respects, lifestyles during the Upper Paleolithic were similar to lifestyles before. People were still mainly hunters, gatherers, and fishers who probably lived in small mobile bands. They made their camps out in the open in skin-covered huts and in caves and rock shelters. And they continued to produce smaller and smaller stone tools.

But the Upper Paleolithic is also characterized by a variety of new developments. One of the most striking developments is the emergence of art – painting on cave walls and stone slabs, and carving tools, decorative objects, and personal ornaments out of bone, antler, shell and stone. (Perhaps for this, as well as other purposes, people began to obtain materials from distant sources.) Because more archaeological sites date from the Upper Paleolithic than from any previous period and some Upper Paleolithic sites seem larger than any before, many archaeologists think that the human population increased considerably during the Upper Paleolithic. And the new inventions, such as the bow and arrow, the spear thrower, and tiny replaceable blades that could be fitted into handles, appear for the first time.

The Last Ice Age

The Upper Paleolithic world had an environment very different from today’s. The earth was gripped by the last ice age, with glaciers covering Europe as far south as Berlin and Warsaw, and North America as far south as Chicago. To the south of these glacial fronts was a tundra zone extending in Europe to the Alps and in North America to the Ozarks, Appalachians, and well out onto the Great Plains. Environmentally, both Europe and North America probably resembled contemporary Siberia and northern Canada. Elsewhere in the world conditions were not as extreme but were still different from conditions today.

For one thing, the climate was different. Annual temperatures were as much as 50 °F below today’s, and changes in ocean currents would have made temperature contrasts (i.e., the differences between summer and winter months) more extreme. The changing ocean currents also changed weather patterns, and Europe experienced heavy annual snowfall. Not all the world was cold, however; still, the presence of huge ice sheets in the north changed the climate throughout the world. North Africa, for example, appears to have been much wetter than today, and South Asia was apparently drier. And everywhere the climate seems to have been highly variable.

Upper Paleolithic Europe

With the vast supplies of meat available from megafauna, it is not surprising that many Upper Paleolithic cultures relied on hunting, and this was particularly true of the Upper Paleolithic people of Europe, on whom we focus here. Their way of life represents a small pattern throughout the Old World. But as people began to use more diverse resources in their environments, the use of local resources allowed Upper Paleolithic groups in much of the Old World to become more sedentary than their predecessors. They also began to trade with neighbouring groups to obtain resources not available in their local territories.

HUMAN BRAIN

The human brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum. The cerebrum, the largest part of the human brain, consists of two cerebral hemispheres.It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making decisions as to the instructions sent to the rest of the body. The brain is contained in, and protected by, the skull bones of the head.

There are three types of brain fore brain, midbrain,hindbrain.The hindbrain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum.Brains are made of soft tissue, which includes gray and white matter, containing the nerve cells, non-neuronal cells which help to maintain neurons and brain health, and small blood vessels. They have a high water content as well as a large amount nearly 60 percent of fat.

FUNCTION OF BRAIN:-

* Attention and concentration.

* Self-monitoring.

* Organization.

* Speaking (expressive language).

* planning and initiation.

* Awareness of abilities and limitations.

* Personality.

* Mental flexibility.

* Inhibition of behavior.

The human brain color physically appears to be white, black, and red-pinkish while it is alive and pulsating. The brain itself does not feel pain because there are no nociceptors located in brain tissue itself. This feature explains why neurosurgeons can operate on brain tissue without causing a patient discomfort, and, in some cases, can even perform surgery while the patient is awake.Brain controls vital functions such as breathing, swallowing, digestion, eye movement and heartbeat, there can be no life without it. But the rest of the brain is obviously capable of some remarkable feats, with one part able to compensate for deficiencies in another.

Anthropology And Its Relation With Allied Disciplines

1. Sociology

Sociology is a science of society that studies human behaviour in groups. Anthropology is a science of man and studies human behaviour in social surroundings. Thus it is clear that the subject matter of sociology and social anthropology is common to a great extent. Anthropologists and sociologists share an interest in
issues of race, ethnicity, social class, gender, and power relations in
modern nations.

2. Psychology

For the psychologists the focus of study is upon all aspects of human behaviour: and its personal, social and cultural dimensions which will never be complete without having the knowledge of social anthropology. Therefore, for understanding the social processes and
meanings in the world around us one has to study social anthropology.
Both Psychology and Anthropology deals with the manifold relations between individuals on the one hand and groups, communities, societies and cultures on the other hand.

3. History

History may be important to social anthropologists in the sense, that is, not only as an account of past events leading up to and explaining the present, but also as the body of contemporary ideas which
people have about these events, people’s ideas about the past are an intrinsic part of the contemporary situation which is the anthropologists immediate concern and often they have important implications for existing social relationships.

4. Folklore

Folklore has an important place in every primitive culture. It
is through the medium of folklores that the culture of a primitive society is
transmitted from one generation to the next generation. Folklores contain
the philosophy of the primitive people. How the world was evolved is a
theme of many folklores of existing tribes. In most of the folklores, a reference to the mutual relation of the people and their gods is given.

Anthropology And Biological Sciences

1. Zoology

In terms of the relationship to other animals and the overall places of the human species in the process of evolutions.
Anthropology has a sort of specialization or sharpening of certain aspects of general biology, more specifically, zoology.

2. Botany

No matter what the time period or geographical area, plants played an important role in human culture. Plant remains enable us to assess human impact on the environment. As direct, site-specific
evidence of agricultural and culinary activities, they enrich our understanding of how people lived.

3. Genetics

Genetic anthropology is the branch of scientific study which deals with combining genetic data with available physical evidence and past history. Genetic anthropology is an important branch
of anthropology. The relevance of genetics in anthropology has slowly been reinforcing the importance of nature (biology) in culture, and also
emphasises on the phenomena of variation. To study evolution, understanding genetics and variation in the anthropological context is
highly vital.

4. Medical Sciences

Quite a few things are common in
anthropology and medicine. In the proper study of mankind, anthropology aims at discovering man as a human being, so it should be the case with a physician. Anthropology can assist more clearly and
satisfactorily in identifying the health needs, and in clarifying factors influencing acceptability and utilisation of health services, and can also assist in showing how these health needs can be most appropriately
solved.

Disaster and disaster management

Catastrophe (Disasters) are classified into three types: naturals, man‐made, and hybrid disasters. A natural disaster is a major adverse event resulting from natural processes of the Earth; examples include firestorms, dust storms, floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis, storms, and other geologic processes. A normal calamity can cause misfortune of life or harm property, and ordinarily clears out a few financial harm in its wake, the seriousness of which depends on the influenced population’s versatility and on the framework accessible.

A landslide is depicted as an outward and descending slant development of an wealth of slope-forming materials counting shake, soil, manufactured materials, or a combination of these. An seismic tremor is the result of a sudden discharge of vitality within the Earth’s hull that makes seismic waves. At the Earth’s surface, seismic tremors show themselves by vibration, shaking, and in some cases relocation of the ground. Volcanoes can cause far reaching pulverization and resulting catastrophe in a few ways. One danger is the volcanic emission itself, with the constrain of the blast and falling rocks able to cause hurt. Dust storm may be a spread of tidy in dry regions. A manmade disaster is more cascading than a natural disaster an example of natural disaster is Bhopal Gas Tragedy.

Bhopal Gas Tragedy, India : Imagine waking up in the middle of the night in agonizing pain with your eyes and lungs burning. You wonder if you’re going to make it. Many don’t. That was the experience countless residents of Bhopal, India had on December 2, 1984 when the Union Carbide India Limited pesticide plant sprang a gas leak. Over 500,000 people were exposed to methyl isocyanine gas and other chemicals. Thousands of people died within the first hours of the leak, but estimates between 5,000 to upwards of 16,000 deaths resulted from the leak overall.

Deepwater Skyline Oil Spill, Inlet of Mexico It’s difficult to disregard the most noticeably awful and biggest oil spill in human history since it as it were happened less than three a long time prior. It begun on April 20, 2010 when an blast on BP’s Deepwater Skyline oilrig murdered 11 specialists, harmed 17 others, and cleared out the well spouting oil. Initially, BP claimed the spill was fair 1,000 barrels per day, concealing the reality that the well was spilling anyplace from 40,000 to 162,000 barrels a day.

Worldwide Warming, Third Planet from the Sun: Global warming is one of the foremost neglected and continuous man-made fiascos — one that will have the most noteworthy long-term affect on humankind. Over the top sums of nursery gasses, especially CO2, presented into the air have expanded normal worldwide temperatures determining a number of desperate results. Impacts from rising ocean levels, desertification, and harm from strongly super storms like Typhoon Katrina have already created a few of the primary bunches of climate-change outcasts and a few appraise that number to rise to 150 million by 2050.

Hybrid disaster is the third type of disaster. A crossover catastrophe may be a artificial one, when powers of nature are unleashed as a result of specialized disappointment or disrupt. There are disasters that result from both human mistake and normal strengths. These are crossover catastrophes. An case of a crossover disaster is the broad clearing of wildernesses causing soil disintegration, and hence overwhelming rain causing avalanches.

Disaster management is how we deal with the human, material, economic or environmental impacts of said disaster, it is the process of how we “prepare for, respond to and learn from the effects of major failures”

Disaster management has three stages which include disaster prevention, disaster preparedness, and disaster response/relief UNISDR sees Calamity Anticipation as the concept of locks in in exercises which proposed to anticipate or dodge potential unfavorable impacts through activity taken in development, exercises planned to supply security from the event of catastrophes. WCPT so also highlight that whereas not all catastrophes can be avoided, great hazard administration, clearing plans, natural arranging and plan benchmarks can decrease chance of misfortune of life and harm relief. The HYOGO System was one such Worldwide Arrange for common Calamity Hazard Decrease, which was received in 2005 as a 10 year Worldwide Arrange, marked by understanding with 168 Governments which advertised directing standards, needs for activity and viable implies for accomplishing fiasco versatility for defenseless communities.

“The information and capacities created by governments, proficient reaction and recuperation organizations, communities and people to successfully expect, react to, and recoup from, the impacts of likely, inescapable or current danger occasions or conditions” “The provision of emergency services and public assistance during or immediately after a disaster in order to save lives, reduce health impacts, ensure public safety and meet the basic subsistence needs of the people affected”

The lingering effects of unexpected emergencies and disasters are different for everyone. Knowing what to do after an emergency can help reduce stress and aid in a quicker recovery. Recovery is a process the process to repair and restore your life after an emergency or disaster is not easy and takes time, flexibility and patience. Examples of recovery include: removing waste and debris, contacting your insurance company, replacing lost or destroyed documentation, finding a new home, getting mental health support etc.

SOLAR ECLIPSE

A solar eclipse occurs when a moon is directly between earth and sun. which fully or partially blocks sunlight.During this earth,moon and sun are in a alignment. Such alignment coincides with a new moon indicating the Moon is closest to the ecliptic plane.

TYPES OF SOLAR ECLIPSE:-

* Total eclipse

* Annular eclipse

* Hybrid eclipse

* Partial eclipse.

TOTAL ECLIPSE:-

A total eclipse occurs when the dark side of the Moon completely observe the bright light of the Sun.During total eclipse totality occurs at only in a narrow track on the surface of Earth. This narrow track is called the path of totality.

ANNULAR ECLIPSE:-

An annular eclipse occurs when the sun and moon are exactly in line with earth but one side of the moon is smaller than that of sun.so that region looks very bright.

HYBRID ECLIPSE:-

It is very rare type of eclipse shifts between the total eclipse and the annular eclipse.sometimes it appears as a total eclipse on other side it appears as annular eclipse.A hybrid eclipse occurs when the magnitude of an eclipse changes during the event from less to greater than one.

PARTIAL ECLIPSE:-

A partial eclipse occurs when the Sun and Moon are not exactly in alignment with the Earth. One partial side of the moon observe the bright light of the sun.The phenomenon is called partial eclipse.It seen most part of the earth.

HISTORICAL SOLAR ECLIPSE:-

The first appearance of a solar eclipse can be found in the Rig Veda, the oldest document from India dated to between 1700 and 1400 BC.

The longest solar eclipse in history is 6 minutes 53 seconds on July 11,1991.

IMPACT OF SOLAR ECLIPSE:-

When in total solar eclipse moon is between earth and the sun. It creates unusual weather conditions.It cause drop in temperature and lack of light.It have impact on weather, animals and plants.

IMPACT ON HUMAN:-

Eye injury: Viewing the eclipse with naked eyes can damage your retina and even lead to blindness.

Digestive issue: The eclipse is believed to disturb the digestive system. For the reason, eating or drinking during the eclipse is to be avoided.

SAFETY MEASURES:-

Projecting the Sun through a box projector, or we can see using binoculars or telescope, or simply 2 pieces of card is a safe and easy way to view a solar eclipse.

CYBER CRIME CASE STUDY IN INDIA

Computer Crime Cyber crime encompasses any criminal act dealing with computers and networks (called hacking).Additionally, cyber crime also includes traditional crimes conducted through the internet. For example; The computer may be used as a tool in the following kinds of activity- financial crimes, sale of illegal articles, pornography, online gambling, intellectual property crime, e-mail spoofing, forgery, cyber defamation, cyber stalking.The computer may however be target for unlawful acts in the following cases- unauthorized access to computer/ computer system/ computer networks, theft of information contained in the electronic form, e-mail bombing, Trojan attacks, internet time thefts, theft of computer system, physically damaging the computer system

Cyber Law is the law governing cyberspace. Cyberspace is a wide term and includes computers, networks,software, data storage devices (such as hard disks, USB disks), the Internet, websites, emails and even electronic devices such as cell phones, ATM machines etc.

Computer crimes encompass a broad range of potentially illegal activities. Generally, however, it may be divided into one of two types of categories

(1) Crimes that target computer networks or devices directly; Examples – Malware and malicious code, Denial-of-service attacks and Computing viruses.

(2) Crimes facilitated by computer networks or devices, the primary target of which is independent of the computer network or device. Examples – Cyber stalking, Fraud and identity theft, Phishing scams and Information warfare.

CASE STUDIES

Case no:1 Hosting Obscene Profiles (Tamil Nadu)

The case is about the hosting obscene profiles. This case has solved by the investigation team in Tamil Nadu. The complainant was a girl and the suspect was her college mate. In this case the suspect will create some fake profile of the complainant and put in some dating website. He did this as a revenge for not accepting his marriage proposal. So this is the background of the case.

Investigation Process

Let’s get into the investigation process. As per the complaint of the girls the investigators started investigation and analyze the webpage where her profile and details. And they log in to that fake profile by determining its credentials, and they find out from where these profiles were created by using access log. They identified 2 IP addresses, and also identified the ISP. From that ISP detail they determine that those details are uploaded from a café. So the investigators went to that café and from the register and determine suspect name. Then he got arrested and examining his SIM the investigators found number of the complainant.

Conclusion

The suspect was convicted of the crime, and he sentenced to two years of imprisonment as well as fine.

Case no:2 Illegal money transfer (Maharashtra)

ThIS case is about an illegal money transfer. This case is happened in Maharashtra. The accused in this case is a person who is worked in a BPO. He is handling the business of a multinational bank. So, he had used some confidential information of the banks customers and transferred huge sum of money from the accounts.

Investigation Process

Let’s see the investigation process of the case. As per the complaint received from the frim they analysed and studied the systems of the firm to determine the source of data theft. During the investigation the system server logs of BPO were collected, and they find that the illegal transfer were made by tracing the IP address to the internet service provider and it is ultimately through cyber café and they also found that they made illegal transfer by using swift codes. Almost has been The registers made in cyber café assisted in identifying the accused in the case. Almost 17 accused were arrested.

Conclusion

Trail for this case is not completed, its pending trial in the court.

Case no:3 Creating Fake Profile (Andhra Pradesh)

The next case is of creating fake profile. This case is happened in Andhra Pradesh. The complainant received obscene email from unknown email IDs. The suspect also noticed that obscene profiles and pictures are posted in matrimonial sites.

Investigation Process

The investigators collect the original email of the suspect and determine its IP address. From the IP address he could confirm the internet service provider, and its leads the investigating officer to the accused house. Then they search the accused house and seized a desktop computer and a handicam. By analysing and examining the desktop computer and handicam they find the obscene email and they find an identical copy of the uploaded photos from the handicam. The accused was the divorced husband of the suspect.

Conclusion

Based on the evidence collected from the handicam and desktop computer charge sheet has been filed against accused and case is currently pending trial.

Hacking is a widespread crime nowadays due to the rapid development of the computer technologies. In order to protect from hacking there are numerous brand new technologies which are updated every day, but very often it is difficult to stand the hacker’s attack effectively. With some of these case studies, one is expected to learn about the cause and effect of hacking and then evaluate the whole impact of the hacker on the individual or the organization.

Sigmund Freud

One day, in retrospect, the years of struggle will strike you as the most beautiful– Sigmund Freud.

Sigmund freud one of the most influential neurologists known to us

An Austrian neurologist and founder of psychoanalysis. He conducted a lot of research throughout his life, and was wrong about a lot of his studies but he still managed to leave a mark in the science textbooks

Made a profound impact on psychology even though he faced a lot of criticism for a lot of his studies. He had a lot of unconventional ideas, he was filled with them. It is known that he studied and pushed the use of cocaine, this also led to one of his close friends getting addicted to the drug.

Sigmund Freud was born in 1856, Freiberg, Moravia, Austrian Empire

At the age of 17, he went to study medicine in the University of Vienna where he studied physiology under Ernst von Brücke. He spent about 6 years in Brücke’s lab where he compared brains of different animals.

In 1882 After graduating from The University of Vienna, he started working in the General Hospital in Vienna as a clinical assistant under the psychiatrist Theodor Meynert and Hermann Nothnagel.

In 1885, went to Paris to study neuropathology at a clinic where he also worked under Jean-Martin Charcot, charot used to work with patients with hysteria which exposed him to psychological disorders and the possibility that psychological disorders might be linked with the mind and not the brain. Charot’s technique of hypnosis left freud quite impressed and was intrigued by the idea of hypnosis

After his return from Paris he established a clinic for neuropsychology for his clinical practice and this could also be termed as the beginning of his psychoanalytic theories. Freud was partners with the physician Josef Breuer for a long time and also published their work together in 1895 Studien über Hysterie (Studies in Hysteria) which was a result of some previous research conducted and their clinical experience.

The next year in 1886 he married Martha Bernays with whom he had 6 children, one of being Anna Freud who followed her father and studied psychoanalysis just like him.

Freud’s psychoanalytic theories further gave birth to multiple concepts. Psychoanalysis is a collection of theories associated with psychology and a group of techniques that deal with the unconscious mind with an attempt to cure mental disorders. It basically involved trying to make the unconscious thoughts of the patient conscious by various methods and when these thoughts were made conscious, they showed improvement. The development of these concepts and techniques were a result of Freud’s working with people and his own clinical experiences.

Now, psychoanalytics is a vast subject and everything mentioned in the article about his contributions was just the tip of the iceberg. It is impossible to cover the whole subject here,it is almost impossible to study and understand all of his work, that is the quality and quantity of work he has done for science and this article doesn’t justice to his work, so I hope it is at least encouraging enough to get you to read more about his studies.

WHY MENSTRUATION A TABOO IN INDIA?

Menstruation is a phenomenon unique to girls. Menstruation is the natural part of the reproductive cycle in which blood from the uterus exits through the vagina. It is a natural process that first occurs in girls usually between the age of 11 and 14 years and is one of the indicators of the onset of puberty among them.

Taboos surrounding menstruation exclude women and girls from many aspects of social and cultural life. Some of these are helpful, but others have potentially harmful implications.

In India especially, I found it extremely ironic for it to be still a taboo in this time and era, even before I don’t understand why it was called a taboo and the reason for that I guess was, India where a girl child recognised as boon ( as GODDESS LAKSHMI when born) and giving birth is also considered boon given only to women despite that this unique process that make it possible for a women to have a child is considered a TABOO. Even with many scientific clarification of the process of this unique phenomenon, even though being this 21st century there still continuous myth regarding this adapted within the society.

SOME OF THEM ARE:

Women who menstruate have long been taught to keep silent about their periods. Young girls are taught from a young age that they have to manage it privately and discreetly.
In Indian households including the literate ones, women are constantly reminded of the old-age traditions where “you are not allowed to touch anything holy, visit temples, cook or touch pickle.”
The taboo is so ingrained that women often have the “walk of shame” while carrying their sanitary pads wrapped in black plastic bags in their hands.
Strangely enough, in some cultures, celebrations are held on the commencement of menstruation. And in the same cultures, the already menstruating women are looked down upon as impure and filthy.
It is not uncommon for boys to giggle and laugh during biology class when the topic of menstruation comes up.
BUT NOT IN EVERY CULTURE IT OCCURS- In Kashmiri Hindu culture, menstruating women are given special care considering the belief that they become weak due to blood loss. They do not consider them to be impure and rules like, a woman on her period can’t visit temples or can’t work don’t apply.

#BREAKTHEBLOODYTABOO

It’s high time that we normalize menstruation as just a healthy and positive part of the female life cycle. Menstrual periods are nothing to be ashamed of. Just like digestion, blood circulation and respiration are considered as natural and biological processes, both men and women should work towards making menstruation an important topic to talk about openly. This is the only way to combat its silence and break the stigma.

some changes I notice toward breaking this taboo for women in this society

The greatest changed I noticed was for the changed working environment toward women as the sanitary environment facilities given to them as employment care like washroom provided with sanitary pads and tampons etc.
knowledge about the first period to young girls now given at their school is compulsory not only to girls but to boys too given knowledge for it be known as normal topic and not as a taboo topic.
Advertisement about sanitary pads and tampons starts to make this topic to talk openly about.
Men buying the sanitary pads and tampons make it comfortable for women during their periods so that they can express their thoughts, sorrows, angers, happiness with them.

He said, she said- Psychology of manipulation.

“Fake it until you make it” has been a life mantra for many. It’s a scenario where you create a lie for yourself and keep believing that lie until it becomes your reality. But what if we are not the ones creating the lies? What if someone else lied to us and we made it our reality?

Hello readers, I welcome you to a new age of MANIPULATION. *cue evil laughter*

The lies we believe-

The term for this is Self fulfilling prophecy given by Robert Merton. The name itself is self explanatory but still I want to give some insight on it. This psychological term in short can be named as misconception that later becomes true cause at first we believed it to be true. So essentially a lie we believed in and subconsciously we commenced our work towards that lie and made it our reality.

Now what if somebody lies to us like “I know what you did last summer.” Pretty vague. No one’s a psychic here. But subconsciously we already start reminiscing what haphazard thing we did last summer hence giving into the manipulation and believing a lie.

Classic manipulation, isn’t it?

The lies made me do it-

Security dilemma is caused by Self fulfilling prophecies. It can lead to people not being able to distinguish between the actual truth and the prophecy discussed above. In general it is a political term which happens only 40% of times in a case of self fulfilling prophecy.

Take it like this, there’s a person, 2 parties A and B and an old age rivalry. So this person who favors none of these parties and wants to stir up some trouble. He goes to party A and says “Hey there, I found these filled water balloons near B. Weird right?” Now that A has evidence that B might be preparing for a water balloon fight they start packing their own balloons and Nerf guns. B part sees the ammunition. And voila blow the toot for a full fledged WATER FIGHT!!!

Now imagine this scenario going on a bigger level and let the realization dawn upon you that how everything is just psychology.

The lies I am-

Talking about Behavioral confirmation, it is a very special kind of self fulfilling prophecy where we change our personality according to someone’s initial belief about us.

Let’s make it clear with an example. Some random person comes up to you and says “When I first saw you I thought you to be a little aggressive.” Now remember this is a person whom you have met only 2-3 times and you are anything but aggressive. Now whenever this person come around you’ll start acting a little aggressive and sometimes even when the person is removed from the equation.

Leading a belief/expectation to turn into reality just like in the 2 cases mentioned above.

All these scenarios are derived from self fulfilling prophecy. A very basic way of controlling human brain according to our wishes. These psychological ways can be used positively too but if you decide to go for manipulation then I didn’t tell you this. Jokes apart, it’s still quite wondrous how a little he said she said shenanigan can be used in our favor.

In the world that we live in today, we are always surrounded by music everywhere. From slow to fast, calm to upbeat, from rock to hip-hop to metal and country, people all over the world appreciate the music in all its different forms, style and distinctiveness. Music connects people all over the world, whatever language or genre that it may have. It carries a universal message of love and togetherness that unites people from different parts of the globe, as they find a common hobby to bond over amidst all the differences and diversity they may have among themselves. We do not overexaggerate when people claim that “Music has saved them”. It is like a boat in the middle of the storm of life that helps them sail through the difficult time with ease and offers them a place to relax and unwind, allowing them time to reflect and introspect to understand themselves a little better. Music is a remedy for all of us and it accepts us with open arms wherever we go.

Some of the ways in which music is beneficial are mentioned below. They are as follows:-

#1 IT HELPS YOU CALM DOWN

Amidst the race and chaos we call life, we may not always get the time to relax and take out time for ourselves. In such situations, music can be our savior. A number of studies have suggested that listening to slow music for a minimum of 15 minutes a day can really help us ease down a bit, allowing our bodies to relax and live in the moment.

So, whenever you feel stressed, make sure to put your favorite tunes on and just relax!

#2 MUSIC MAY HELP YOU IMPROVE YOUR PERFORMANCE WHILE EXERCISING

Often, people prefer listening to upbeat and groovy music while trying to get in a workout. This is highly beneficial as it can truly help us stay motivated to give our best while doing exercise and may help us improve our daily performance. Many researches have shown that listening to happy and motivational music may help us get motivated to run even faster while running as well as help build our strength and stamina.

#3 MUSIC CAN HELP ELEVATE YOUR MOOD

Scientific studies have shown that music can actually help release dopamine, a feel good hormone, in our body and improve our mood a lot. Henceforth, listening to music about 30 minutes a day can make us significantly happier and elevate our mood!

#4 MUSIC IS GOOD FOR YOUR HEART

A number of scholars and professionals have stated that while music does make US happy, it also makes our heart happy too. This evident through the fact that listening to music helps the blood in our body to flow more easily and efficiently, while at the same time, it lowers our blood pressure as well. Not only this, listening to music can also help in lowering the cortisol levels in our body as well as increase the production of serotonin in our lood stream, making us less stressed and happier.

So, listen to music everyday while enjoying the journey of life!

CANCER

WHAT IS CANCER?

The abnormal growth of cells anywhere in the body causes cancer. These cells are called cancer cells. These cells destroy the normal tissues in the body. Normal body cells grow, divide and die in an orderly way whereas cancer cells continue to grow and divide in a disorderly fashion and these cells do not die. These cells form a tumor. But, not all cancer cells form tumors. Cancer can occur at any age but 67% of cancer deaths occur in people who are 65 years. There are two types of tumors. Malignant tumors and benign tumors. Malignant tumors spread to other parts of the body at a rapid speed. It spreads to other parts through the bloodstream and lymphatic system. Whereas benign tumors stay in one place and start to grow slowly and expand in the same tissue. Although cancer is common, 5-10% of it can be hereditary, i.e they are inherited from their parents. The inherited cells undergo mutation and cause cancer.

CAUSES OF CANCER:

There are several causes of cancer. The substance that causes cancer is known as a carcinogen. This carcinogen affects the normal growth of cells.

Lifestyle factors: Smoking, drinking alcohol and drugs high fat-diet, and working with some toxic chemicals are the risk factors that may cause cancer in adults.

Inheritance: Cancer cells can also be inherited from our past generation to the present generation in some cases. It may be caused by a genetic mutation, exposure to chemicals in the living residence, or a combination of these factors.

Genetic disorders: Some syndromes like Wiskott-Aldrich and Beckwith-Wiedemann syndromes are responsible for altering the immune system. The immune system helps to fight back against diseases and infections. Sometimes the stem cells in the bone marrow become damaged and when they reproduce, it results in the growth of cancer cells. The stem cells are damaged by some inherited genetic defects.

Environmental exposure: The use of pesticides and fertilizers in the growth of food plants have a direct link to childhood cancers. There is also evidence of cancer occurring in a child who lives in a polluted environment.

TYPES OF CANCER:

Cancers are classified into four types based on where it is found.

Carcinomas: This type of cancer appears in the epithelial tissues of the skin or some inner tissues of the internal organs. Carcinomas may spread to other parts of the body or it may develop in the same tissues where it was provided. The risk of carcinoma increases with age, alcohol consumption, tobacco use, exposure to ultraviolet rays. Examples of carcinomas include breast cancer, lung cancer, liver cancer, colorectal cancer, and prostate cancer.
Sarcomas: Sarcomas appears in the tissues that support and connect the body. Sarcomas can develop in fat, joints, blood vessels, muscles, nerves, lymph vessels, bones, cartilages. Example: Bone cancer (osteosarcoma), liposarcoma in fat, and rhabdomyosarcoma in muscles. Sarcoma occurs in both children and adults.
Leukemia: Cancer that occurs in the blood is known as leukemia. Leukemia involves white blood cells (WBCs). WBCs are responsible for fighting against infection and diseases. Normally they grow in an orderly fashion. But in the case of leukemia, the bone marrow produces more amount of WBCs, and those cells do not function properly. Example: Blood cancer.
Lymphomas: It begins from the lymphatic system. The lymphatic system consists of vessels and glands that help in fighting against infection. The most common types of lymphomas are Hodgkin lymphoma and non-Hodgkin lymphoma.

TREATMENT:

Some of the cancers will have only one treatment. But most of the cancers have combinations of treatment such as radiotherapy, chemotherapy, and surgery.

Chemotherapy: In this treatment, drugs are used to kill the cancer cells. The disadvantage is that it may also affect the normal cells and bone marrow and causes loss of hair and loss of weight and it reduces the immune responses.

Radiotherapy: In this treatment, high-energy rays are used to kill the cancer cells. These rays stop the growth and division of cancer cells. Some of the side effects are skin rashes, lowers WBCS count, and loss of appetite.

Surgery: In this treatment, the person has to undergo the surgery to remove the entire mass of cancer cells i.e, tumors in a particular area. In some cases, the only way to know if the person has cancer or what kind of cancer he has is by removing small tissue from the tumor and testing it.

PREVENTION:

Always eat healthy foods.
Consume more vegetables and fruits.
Exercise regularly to keep your body fit and free from diseases.
Don’t smoke and don’t drink alcohol.
Minimize your exposure to harmful rays and chemicals.
Avoid usage of tobacco. Reduce your exposure to the sun.
Consume nuts reduces the risk of cancer

We should follow preventive measures to avoid cancer. If already cancer has occurred, one has to undergo proper treatment.

Why is Earth the only planet with life?

Not so fast,Earthling ! Outer space is a big place, and one thing scientists have learnt from studying life on Earth is that organisms can thrive in all sorts of harsh environments. Meanwhile, astronomers have discovered nearly 4,000 Earth like planets beyond our solar system and are spotting more everyday. Some of these ” exoplanets ” orbit their stars in the “Goldilocks zone”, a distance that neither too hot nor too cold to support liquid water and possibly alien life. Who knows? Maybe an alien kid somewhere up there is wondering if you exist.

Why does Mars have a face on it?

When the Viking I aur picture pictures of Mars in 1976, one photo became a hit for its apparent portrayal of a mountainous Martian face resembling An Egyptian Pharaoh. Eager to set the record straight on this crowd- pleasing Mars anomaly, NASA used a satellite to re photograph the region in 1998 and 2001. The high resolution images revealed a natural geological feature rather than a monument to Martiankind.

How many exoplanets might support life?

After analysing the known exoplanets and comparing that data with what they know about the Milky Way, astronomers at Cornell University predict that as many as 100 million worlds in our galaxy could support complex life.

So why we haven’t met aliens yet?

Because space is big. The galaxy might be teeming with life, but the gulfs between stars make visiting our neighbours an impossible mission – at least for now. Remember, it would take thousands of years to travel to the closest star outside our solar system using modern spaceship technology.

What about the possibility of life closer to home?

Where? Like in London? Ah, you mean in our solar system! Mars was once considered a top candidate for alien life,but so far we haven’t found any Martians. ( Anything that lived on the red planet is most likely long dead). Astronomers seeking signs of life are now turning their attention to the solar system’s moons instead of its planets.

Why did people once think Martians lived on Mars?

Astronomers peering at mass in the 17th,18th, and 19th centuries saw signs of life everywhere. Seas ! Continents ! Canals that carried water to Martian farms ! But modern telescopes, probes, and NASA landers ruined the fun by revealing our planetary neighbor’s dry details:It’s just a lifeless ball of red rock. Early astronomers had confused Mars’s ancient seas and riverbeds for signs of civilisation.

Which of the solar system’s moons might have life?

The Frozen surface of jupiter’s moon Europa hides a liquid Ocean that might contain alien creatures. Enceladus, one of Saturn’s many moons, has a sea the size of Lake Superior under its icy surface. And Titan, Saturn’s largest moon, has vast lakes of liquid methane. If life existed here, it would be truly alien.

How are astronomers searching for alien life?

BY DIGGING: Robotic rovers are sampling Martian soils for science of ancient life.
BY VISITING: Probes are being dispatched to spots across the solar system that might harbor life today.
BY LOOKING: NASA’S Earth- and space -based telescopes have been scanning galaxy for earth like exoplanets outside our solar system capable of supporting life.
BY LISTENING: In 1960, scientists began scanning the universe with special telescope for radio signals from alien civilizations. The project is called SETI, for the Search for Extraterrestrial Intelligence. It hasn’t picked up any alien broadcast yet, but we haven’t stopped listening.

Why is the U.S government hiding evidence of alien life?

Ah, you must be thinking of the “Rosewell incident”, in which an unidentified craft crashed near the small town of Roswell, New Mexico, U.S.A., in 1947. Conspiracy theorist claim the craft was a flying saucer and that the U.S military whisked away the wreckage along with the bodies of its alien pilots. The U.S government released a report on Rosewell in the mid -1990s claiming the debris was actually a crashed balloon in its top-secret “Project Mogul,” which used high-altitude sensors to monitor for enemy nuclear-missile tests. “Likely story,” claim the conspiracy theorists.

Milestones in India’s science and technological development

The fashionable age is the age of science, technology and knowledge in which all of these are interrelated and are different aspects of the same thing. Explosion of knowledge and data , supported breathtaking advancement within the world of science and technology, has bestowed on man powers enviable even for gods. it’s helped man conquer space and time. Now one has unraveled many mysteries of nature and life and is ready to face new challenges and move forward within the realm of the unknown and thus the undiscovered. In India there has been an extended and distinct tradition of scientific research and technological advancement since the past .

Since independence, India has accelerated it’s speed and efforts in this field and have established many research laboratories, institutions of upper learning and technical education. The results would make anybody’s heart swell with pride , confidence and fulfillment. The best, however, is yet to return . The central and state governments, various public and private sector establishments are engaged in scientific research and technological development to require the state on the trail of rapid development, growth and prosperity. There are about 200 research laboratories spread everywhere in the country. The institutions of upper learning, and universities, the fashionable temples of learning, are all committed to need the country forward. they’re well equipped and staffed to secure for the people of the state all the blessings and benefits which can accrue from the acquisition and application of knowledge and technology. But there is no room for complacency, for during this field only the sky’s the limit and that we are yet a developing country.

Our technology policy is comprehensive and well thought out. It aims at developing indigenous technology to ensure efficient absorption and adoption of imported technology suitable to national priorities and availability of resources. Its main objective is attainment of technical competence and self- reliance, leading to reduction in vulnerability in strategic and important areas.

With a view to strengthening our economy and industrial development, our government has introduced many structural reforms through adoption of a replacement industrial policy which features an important pertaining to the programmes of development concerning science and technology. Consequently, technology has become our mainstay enterprise and now we’ve built a robust and reliable infrastructure for research, training and development in science and technology. Within the field of agriculture, our scientific and technological researches have enabled us to be self-reliant and self-sufficient in food grains.

Today, India withstand droughts and natural calamities with much greater confidence than ever before. Now, we are at an edge to export food grains, etc. and are on the sting of white and blue revolutions. Our agricultural scientists and farmers, who are always ready to imbibe new technologies, our country has many kinds of hybrid seeds, crop- protection technologies, balanced farming practices and better water and irrigation management techniques. Similarly within the sector of economic research, we’ve achieved many milestones and India is emerging as a significant industrial power of the earth .

The Council of Scientific and Industrial Research (CSIR), which has its network of research laboratories and institutions, has been chiefly instrumental in our major achievements in scientific and industrial research. We’ve now joined the exclusive club of six advanced nations by developing our own supercomputer at the Centre for Development of Advance Computing (C- CAD) at Pune. Our Atomic Research Commission, acknowledged in 1948, is engaged in valuable nuclear research for peaceful purposes. The chief agency for implementing atomic energy programmes is the Department of atomic energy . The Bhabha Atomic Research Centre, Trombay, near Mumbai is the most important single scientific establishment within the country, directing nuclear research. Now, we’ve five research reactors, including Cyrus, Dhruua, Zerina and Purnima. We’ve administered two underground nuclear tests at Pokhran in Rajasthan.

This is often an interesting achievement by our nuclear scientists, which has enabled us to become one of the chosen few countries on earth to have done it. India is additionally the first developing country, and one of the seven countries of the earth to master fast breeding technology. Research in breeder technology is currently happening at Gandhi Centre for Atomic Research at Kalpakkam, Chennai. The successful launching of the Polar Space Launching Vehicle (PSLV- D-2), in October 1994, marked India’s entry into the league of the world’s major space powers. Within the INSAT-2 series of satellites, launched first in 1992, India has shown its ability to fabricate complex systems like anything made anywhere within the earth . Our previous launches of the SLV-3 and thus the SLV were merely stepping stones to what’s going to be the workhorses of the business, the PSLV, which can launch one tone satellite into orbit of up to 1000 km, and therefore the Geosynchronous Satellite Launch Vehicle, which can take 2.5 tonne satellite to orbits 36,000 km away. India’s space programme rocketed to greater heights with the successful launch of the second Geosynchronous Satellite Launch Vehicle (GSLV-D2) in May, 2003. As has been rightly observed, the challenge before Indian Space Research Organisation (ISRO) is to take care of the momentum of the programme by integrating it with other missions. The foremost obvious ones are related to military communication and reconnaissance.India’s first space mission to specialize in an extraterrestrial landing, Chandrayaan-2, would have commenced by the time you read this. It’s a symbol achievement for India’s technological capability, in areas ranging from propulsion , signals and communications, materials, robotics, remote guidance and even AI , to let the lunar lander navigate on its own on the far side of the moon. If successful on all targeted fronts, it’d also increase humankind’s understanding of cosmology and thus the origins of the planet , because the moon probably could also be a piece of this planet that got thrown out at a stage when it had been mostly molten matter. And, of course, it’d cause greater understanding of the moon itself, its chemistry and composition. America landed men on the moon essentially to demonstrate that it had overcome the Sputnik scare — the shock realisation that the Soviet Union was before it in space science and technology which its own education system had to repair for greater specialize in science and maths — and had beaten the Soviet Union therein lone area of human achievement during which the Communist nation had been ahead.

Achievements in space still have a component of demonstration of technological capability, apart from their intrinsic utility. So, becoming the fourth nation within the world, behind the US, the previous Soviet Union and China, to land a mobile explorer on the moon, tells the earth of India’s capability altogether the intricate technologies that are marshalled and harmonised to carry out Chandrayaan-2, its predecessor having orbited the moon with a proximity of 100km. The mission, conceived in 2008, has taken 11years to end . The mission director and thus the project director are both women, to boot. The Indian Space Research Organisation is standing testimony to the overall public sector’s capacity to deliver outstanding results, when given autonomy and resources. There’s a case for similar public sector initiatives in cyber security, telecom systems and AI . What it lacks is political vision and commitment. Our success on Antarctica speaks volumes of our scientific genius and technological wisdom within the world . So far, 13 scientific expeditions by our oceanographers,scientists and technicians are to Antarctica where we’ve two permanent stations on the icy continent. within the field of defence also our achievements are quite laudable.

The successful production of such missiles as Prithvi and Nag testify to the high capabilities and achievements of our scientists. we’ve also been successful in producing opt-electronic preparation and night-vision devices required for our indigenous tanks. The HAL at Bangalore has already produced the Advanced Light Helicopter (ALH). Obviously, technology has been used effectively as a tool and instrument of national development and yet much remains to be achieved so that its benefits reach the masses. Scientists within the country will strive hard to bring technological developments to people’s doorsteps.

Therefore, they can not rest on their laurels, but should remember the famous and galvanizing lines of the poet Robert Frost: The woods are lovely, dark and deep, But I even have promises to stay, And miles to travel before I sleep……

What are germs?

The term “germ” encompasses an army of tiny terrors, including viruses, fungi, parasites, and bacteria. These “pathogens” all have the ability to spread from victim to victim(called a host). Germs are so small you can see them only through a microscope. They look like spiky blogs, oozing spirals,hairy hotdogs, or other microscopic monsters.

Why are germs bad for us?

These microorganisms hitch a ride into our bodies on the food we eat, in the air we breathe, or through a variety of other methods. Once they have invaded our personal spaces, germs reproduce and create toxic waste, which triggers our body’s most repulsive reactions. They make us sniffle, upchuck, run to the toilet, break out in rashes and fevers, and suffer even more unpleasant symptoms.

How do we get sick from viruses?

Most viruses are frail little things ( unlike bacteria and fungi, viruses are not even alive ) that can multiply only inside a living host ( including animals, plants, and even bacteria). There they spread overwhelming and attacking the host’s immune system and causing all sorts of nasty symptoms. Colds, flus, chicken pox, immune disorders, and measles are caused by viruses. Among the worst is a Ebola, which triggers bleeding and is fatal more than half the people who catch it.

How do we get sick from fungi?

Fungi are microscopic molds, yeasts, and other plant like pathogens that thrive in wet, warm places like our armpits, our belly buttons, and the dank spaces between our toes. They feed on our respect and dead tissues and produce stinky wastes that irritate our skin.

How do we get sick from parasites?

This ghastly germ group includes itty-bitty insect larvae, amoebas, and one celled organisms called Protozoa that live in nasty food, damp soil, or dirty water. Parasites depend on a living host for their survival. They sneak into our bodies in tainted water and food, costing of all sorts of gastrointestinal gripes: diarrhoea, vomiting, upset stomachs, and worse. Malaria – common diseases that causes chills, shaking, and fevers – is spread by a parasite passed in mosquito bites. These life-sucking relationships are often the stuff of nightmares.

How do we get sick from bacteria?

Unlike viruses, bacteria are living single celled organisms that can reproduce both outside and inside the body. Like all living things, bacteria create waste -microscopic poops that can act as a poison inside the host. You can blame sore throat, ear infections and tooth-tartar buildup on bacteria. One of the most famous bacteria is Escherichia coli. This rod shaped micorbe lives deep in your intestines, the body’s busiest bacterial neighborhood. Harmful ones make you puke for days.E.coli strains produce an important vitamin. That’s right – some bacteria are actually good for you!

How many bacteria are inside our body right now?

Your body is built of trillions of itty-bitty living blobs, called cells, that work together to make you you. But for every cell you call your own, ten foreign bacteria cluster around or near it. You are a microbe metropolis! Scientists call these communities of foreign bacteria your body’s “flora”, and no two people host the same mix of microorganisms. In fact, scientists are beginning to think of your flora as just another organ.

Can we see these bacteria?

No, they are microscopic. But you can certainly smell them. Like any living thing, bacteria eat, reproduce,die, and create waste which can make your life stink – literally !(Bacteria are the source of bad breath and body odor.)

Benefits of Bacteria

Your gut reaction might be to wrinkle your nose at the thought of bacteria inside your guts, but it turns out that many so-called good bacteria are essential to your health, the survival of life on Earth, and the making of tasty foods. Behold, the benefits of a microscopic allies…

Health boosting

Your body’s microbes support your immune system, which fights sickness.

Plant feeding

Blue-green algae and other types of bacteria convert the nitrogen in the air into compounds plants can use.

Food processing

Micorbes in our innards play a huge role in the digestive process, helping us absorb nutrients and vitamins from our food.

Food making

Bacteria are a vital ingredient in the process of turning milk into yogurt and tasty cheeses. The holes in Swiss cheese are created by carbon dioxide bubbles exhaled by bacteria during the cheese making process.

Planet Cleaning

Bacteria breakdown dead animals and plants, which “decompose” into nutrients for the living.

Attraction

Ever thought why do we get attract to someone? Well everyone has different answer to it. For some it can be the way one look, smiled, walk or may be their was an unusual aura around that one.

What is attraction?

Attraction, especially in a romantic way, is a complex process that take place in our brains, and has had it’s roots since it’s beginning of the humankind. It’s our minds way of telling us who has the potential to be our partner, our friend, or even our soulmate, and is based on a complex blend of our interest, values, experience, and desire. Physical and romantic attraction, which are often focused on, are only small facets of a much larger equation.

Psychologist look at the ingredients of attraction is in a form of pyramid, split into 4 different sections.

The base of the pyramid is made up of health and status:-

Status – 1. internal (confidence, self set, beliefs) 2. External (person’s job, possession and appearance.

Health – Physical attributes, smell, basic level of intelligence.

If the potential partners passes these initial requirements then we move to the center of the pyramid, which are the emotional factors:- includes

trust comfort someone wants,
their emotions intelligence, and
unique characteristics.

The final portion of the pyramid is “Logic”.This is the part that differentiate us from other animals, and is the part where our brains seriously

considers whether we are totally compatible for that person.
It ensure that the other person is aligned with us in term of what they want – things such as marriage, children, even the city they want to live.

According to this model, the more alignment there is, the more attraction there is, but it doesn’t always have to follow from bottom to top – like online dating.

What makes someone Attractive?

The answer to this questions make come to our mind is physical traits. Due to the influence of media, we tend to favor women who is younger, and more feminine features, in men on the other side, qualities such as broad shoulders, a deep voice, and strong jawline are highly upon.

Scientists suggest that, these also have an evolutionary origin because these traits are associated with a higher chance of producing health offspring and passing of good genes. Also, values, culture, and the environment, that we grow in also plays an important role.

Hence, attractiveness is complex, there’s a number of different perspective to consider, and at the end of the day, there’s very little we can choosing who we are attracted to. As each person looks for unique set of traits and, while physical traits are often focused there are far more factors that come into play. A person’s upbringing, behavior and even lifestyle have major influence. The most important thing to remember is to be happy and make the most of it.

Why do we have 10 fingers?

Scientists have several ideas why humans can high-five each other instead of, say, high four or high six. One theory suggests four fingers and a thumb on each hand are the perfect number and length to grip objects firmly. (Another study suggests we can gasp most things with just our thumb and index finger if necessary ; the other four fingers are spares).

The process of evolution determined the most beneficial number of fingers and toes for our survival. Pandas, after all, have thumblike digits to help them grasp bamboo shoots, while some birds have quadruple digits for perching and tucking away during flight. Occasionally, babies are born with extra fingers and toes (a condition known as polydactyly), but those additional digits have never offered enough of an edge to survive to later generations. In other words, evolution determined that five fingers per hand are just right for humans.

Why do we have thumbs?

Having no thumbs would make you all thumbs, fumbling to tie your shoes or assemble a hamburger. (Don’t believe us? Tape one of your thumbs against the side of your hand and see how hard life becomes). We inherited a fully “opposable” thumb named for its ability to close tip-to-tip against our other fingers – grom our primate ancestors around two million years ago. These ancient relatives needed handier hands to help get a grip on simple tools. So give a thumbs – up to your thumbs. So give a thumbs – up to your thumbs. They are the main reasons you can text with one hand and build a burger without fumbling the bun.

Do other animals have thumbs beside us?

Lots of them, although the exact number depends on your definition of “thumbs”. Apes and many monkeys have opposable thumbs just like us, while smaller primates, pandas, and koalas have thumblike digits and claws that help them grip plants and prey.

Why do we have fingerprints?

Those whirls, swirls, loops, and arches on your fingertips (and toes, in case you didn’t know) are hnique to you – even if you have an identical twin – and they remain unchanged throughout your entire life. In fact, the faint ridges known as fingerprints form before you have ever born. Fluids in the womb put pressure on your developing digits, which, combined with your rate of growth and genetic makeup, create one-of-a-kind designs.

Okay, but why do we have fingerprints?

Ah, you want to know the point of those fingertip designs ( well, besides incriminating crooks who forget to wear gloves). Scientist have put forth all sorts of possible reasons. Fingerprints might magnify the hand’s ability to detect vibrations, for example, or improve our sense of touch. They also might work like tyre trying to help They also might work like tire treads to help us grip objects.

Why do my fingers wrinkle when we’ve been swimming?

You might think that playing in the pool or soaking in the tub makes your fingertips and toes waterlogged and soggy. Not so ! The prune effect is caused by blood vessels bringing just below the skin – an automatic reaction triggered by your nervous system when it senses long exposure to water. Scientists think people evolved this reaction to improve their grip and traction in wet environments. After all, pruny fingers make it easier to snag slippery fish.

Why can we pop our knuckles?

When you move or bend your fingers, you occasionally squeeze tiny air bubbles that form in the protective fluid around your body’s joints.Those poping bubbles create an audible crack.

LUCID DREAMS

We spend one third of our life dreaming. Sometimes dreams are happy, scary, unexplainable and even an indication of what is going to happen in future. There is a popular saying that the dreams we see in the morning are usually true and real, though there is no scientific proof to it. We usually dream what we think, stress is an important factor in dreams. Less stress means happy dreams.

But will you believe it if I tell you that you can actually control your dreams?🤔
A dream where one becomes aware of the dream it is known as lucid dreaming. And there are people who do this. You can do it too!! Let’s know how.
People have been studying lucid dreams for a very long time, from ancient to modern it has been studied to understand the cause and purposes of it. As a result many theories have emerged, though it is still under research.

This term was given by Dutch author and psychiatrist Fredreik Van Eeden. In his article A Study of Dreams in 1913. He studied his own dreams for a period of time and wrote them in his dream diary, 352 of his dreams were categorized as lucid.
He mentioned 7 different types of dreams and out of which he considered lucid dreams most interesting and worthy of observation.
The reference to this phenomenon can be found in ancient greek writings. According to Aristotle, Greek philosopher, “often when one is asleep, there is something in consciousness which declares that what then presents itself is but a dream”. Other than Aristotle, physician Sir Thomas Browne, Samuel Pepys and more have mentioned lucid dreaming.
In 2020 there was a large increase in reports of lucid dreams compared to the previous year.

There are a few conditions for a dream in order to be defined as a lucid dream and these were given by Paul Tholey. The conditions are:
1. Awareness of the dream state (orientation)
2. Awareness of the capacity to make decisions
3. Awareness of memory functions
4. Awareness of self
5. Awareness of the dream environment
6. Awareness of the meaning of the dream
7. Awareness of concentration and focus (the subjective clarity of that state)

Lucid dreams are often found to be affective in treating nightmares. Physiotherapists have also been including lucid dreaming as a part of therapy. There are also books and movies based on this like inception, paprika, etc.
Though lucid dreaming has been beneficial in many aspects but for the people who experience it for the first time can go through the feelings of stress or confusion. People who see lucid dreams very often might feel empowered and also isolated from others in terms of their dreaming experience which is quiet different to others. Others might experience sleep paralysis, which is sometimes confused with lucid dreams.

Read about sleep paralysis here: https://edupub.org/2021/08/12/sleep-paralysis/

There are many methods using which one can experience lucid dream like, make a dream diary and jot down the dreams you remember, diary alone won’t help but it will be beneficial with other methods. Some devices and drugs are also used.

Disaster & Disaster Management

A disaster is a sudden, calamitous event that seriously disrupts the functioning of a community or society and causes human, material, and economic or environmental losses that exceed the community’s or society’s ability to cope using its own resources. Though often caused by nature, disasters can have human origins.

The word disaster implies a sudden overwhelming and unforeseen event. At the household level, a disaster could result in a major illness, death, a substantial economic or social misfortune. At the community level, it could be a flood, a fire, a collapse of buildings in an earthquake, the destruction of livelihoods, an epidemic or displacement through conflict. When occurring at district or provincial level, a large number of people can be affected. Most disasters result in the inability of those affected to cope with outside assistance. At the household level, this could mean dealing with the help from neighbours. At the national level, it could mean assistance from organizations, various non-governmental organizations (NGOs) and government agencies themselves. As the limiting factor in disaster response is often the coping capacity of those affected, improving their resilience when responding to disasters is a key approach to lessening the consequence of a disaster.

There is no single measure of a disaster that can capture the full scope of a disaster. A common measure is the number of people killed or affected. The individual will consider the impact on his or her family and livelihood. Disaster managers will assess the speed and success of the disaster response. Economists will measure physical loss to houses and buildings and loss of production. Politicians will assess political damage from a poor response by state agencies. Health workers will consider the resources required to contain an outbreak of Ebola or Coronavirus. Others may focus on the nature of the hazard, the social consequences and the impact to specific elements of the infrastructure. To think seriously about a disaster means we must consider all affected and their losses both in the immediate and the longer term.

A disaster may occur with or without a warning phase. A response is made following a disaster. The response may be helped substantially by any preparedness actions which were made before the disaster occurred. Relief activities occur during the emergency phase, which follows the impact of the disaster.

General Effects of Disasters

The typical effects of disasters may be one or more of the following :

Loss of life
Injury
Destruction of property, plantations and crops
Disruption of production, lifestyle & transport
Loss of livelihood and occupation to people
Disruption to essential services like electricity, water supply and gas supply
Damage to national infrastructure
Disruption of communication and other networks
Disruption to government systems and schemes
Shortage of food resources
Spreading of diseases
National economic loss
Sociological effects
Psychological after effects.

Types of Disasters

There are 2 major types of disasters :

1. Natural Disasters

A natural disaster can be defined as a major event brought about by the natural processes of the Earth that causes widespread destruction to the environment and loss of life. The list of natural disasters include weather phenomena such as tropical storms, extreme heat or extreme cold, winds, floods, earthquakes, landslides and volcanic eruptions.

Management of Natural Disasters

Early warning systems can alert costal populations of approaching tsunamis and they can give populations time to be evacuated from danger areas.
Responsible land use can reduce the risk of landslips caused by unchecked felling of trees. For other events classified as natural disasters, risks can be dramatically reduced through careful planning.
Construction codes when enforced can reduce loss from earthquakes. Governments can institute measures to assist in extreme cold and extreme heat.
Food security programmes can protect a population against food crisis arising from pests and failed crops.
Surveillance systems and high coverage by routine immunization programmes can help prevent outbreaks of disease.
Social programmes can reduce vulnerability to disasters which otherwise could not be controlled.

Types of natural disaster

Natural disasters may be broadly grouped into major and minor types depending upon their potential to cause damage to human life and property. The disasters like earthquakes, volcanic eruptions, droughts, floods and cyclones could be regarded as major types. The disasters like hailstorms, avalanches, landslides, fire accidents, etc. whose impact is localised and the intensity of the damage is much less than the others may be categorized as minor disasters.

Natural disasters can be categorised into 4 parts :

Geophysical (e.g., Earthquakes, Landslides, Tsunamis and Volcanic Activity)
Hydrological (e.g., Avalanches and Floods)
Climatological (e.g., Extreme Temperatures, Drought and Wildfires)
Meteorological (e.g., Cyclones and Storms/Wave Surges)

2. Man-Made Disasters

Man-made disasters are extreme hazardous events that are caused by human beings. Some examples of man-made disaster emergencies include chemical spills, hazardous material spills, explosions, chemical or biological attacks, nuclear blast, train accidents, plane crashes, or groundwater contamination.

Man-made disasters have an element of human intent, negligence, or error involving a failure of a man-made system, as opposed to natural disasters resulting from natural hazards. Such man-made disasters are crime, arson, civil disorder, terrorism, war, biological/chemical threat, cyber-attacks, etc.

Man-made disasters can be caused by :

Environmental Degradation
Pollution
Accidents (e.g., Industrial, Technological and Transport usually involving the production, use or transport of hazardous materials)

Though weather and geologically related disasters are considered to have generated the greatest number of deaths and economic loss, disasters generated by humans are increasing in importance. As society has become more complex, it is evident that people are increasingly responsible, directly or indirectly, for the consequences of events previously ascribed to forces beyond their control. Globalization is now carrying industrial production to previously agrarian societies. The risk from the unintended release of hazardous materials is becoming ever more widespread. Potentially hazardous products are now available in communities and populations which do not have adequate regulations governing their use and, in fact, may not even be aware of their presence or health risks. Rapidly increasing transport of people and commodities across continents means that transportation disasters pose increasing threats to millions.

Disaster Management

Disaster Management can be defined as the organization and management of resources and responsibilities for dealing with all humanitarian aspects of emergencies, in particular preparedness, response and recovery in order to lessen the impact of disasters.

Disaster management conveys the important idea that protecting populations and property also involves the estimation of risks, preparation, activities which will mitigate the consequences of predictable hazards and post-disaster reconstruction in a way that will decrease vulnerabilities. An important goal is building a culture of awareness that preparation is not only possible, but also will greatly reduce the consequences from disasters in terms of human and economic loss.

An effective response to disaster begins with effective planning, but must include many other steps. Each of these steps depends on the strength of other links in the disaster management chain. While no one organization or group ‘owns’ a disaster, the ultimate responsibility rests with governments to protect its people against disaster. No government can carry out these responsibilities without cooperating with many other groups in a country. Disaster management planning is often seen as a separate activity from the main functions of governments and organizations.

Conclusion :

Disaster management is the only way to mitigate the effects of all these hazards. Advance planning is always needed to keep the items of emergency for any disaster. Guidelines are also to be prepared in the form of booklets and circulated to the educated individuals. Awareness camps are to be organised for public. Training is yet another initiative. Training involves the duties and responsibilities, efforts to sustain, role of employees/NGOs, risks, errors, behavioural patterns, recovery techniques, communication channels, safety rules, priorities and security measures. Knowledge of water quality, sanitation, first aid, emergency medicines, electricity controls and gas usage are needed. Evacuation, reporting and alert procedures, are the other major initiatives. Proper insurance policies, alterations to existing buildings, changes in business locations and other resources are to be planned, for future disaster mitigation.

Why can I survive without all my organs?

It is a no-brainer that you need your brain and your heart, hurtand you wouldn’t last long if your liver failed.

But the lungs and Kidneys come in pairs, so you could survive if one of them failed. People who have lost their spleens in accidents have gone on to live healthy lives. The tonsils and appendix, meanwhile, are practically useless and are routinely removed when they become inflamed.

Why are some body parts pointless?

Called “vestigial” organs, this useless body parts are leftovers from our evolutionary ancestors, who actually needed them. Take your wisdom teeth, for example.Today crowd our mouth and often need to get yanked by the dentist, but our primate ancestors had larger jaws and needed the extra choppers in case some rotted away in the days before tartar-control toothpaste. Our tailbone – or coccyx – is a leftover from animals that needed tails for balance or grasping branches.

Why do we have eyebrows?

Humans have evolved to become less hairy in the past six million years or so, but we still have those clumps of fur above our eyes.Beyond their role in facial expressions, eyebrows act like natural sweatbands, preventing rain and sweat from running directly into our eyes.

Why do we have nipples?

They were there even before you were even born. Human embryos in the womb develop according to a blueprint that’s design for males and females. Eventually, the embryo begin to take on features specific to their gender, but not until after they have already developed nipples. Later in life, chemicals called hormones trigger changes in females so that they can nurse their young. Males don’t have those hormones, so they are stuck with nipples that are nothing more than chest accessories. Other than a few exceptions ( mice, platypuses, stallions), most male mammals have nipples. Nipples don’t cause males any harm, which is probably why evolution hasn’t given them the ol’ heave – ho.

Why do people get goosebumps?

Like youryou are wisdom teeth and your tailbone, goose bumps serve no purpose in modern humans. They are created by itty-bitty muscles in our hair follicles, which raise the bumps as a reflex reaction sudden drop in temperature or feelings of panic, or anger, or extreme fear. Goosebumps fluffed up the body hair of our much furrier ancestors to help trap heat or make them look larger to threatening animals. Today, goose bumps just make you look like you need to borrow a sweater.

Why do we have a belly button?

For the same reason dolphinsthe same reason dolphins, cats, dogs, bats, and other “placental mammals ” – animals nourished inside their mothers before birth – have navels. In other words, you can thank your mother for that link connector on your stomach. Before you were born, when you were still developing in the womb, you were hooked up to your life – support system through a special code that plugged into your navel. Through this “umbilical cord “, you received food and oxygen and passed waste. The day you were born, you let out a cry and began breathing on your own. That let the doctor know he or she could cut off the umbilical cord, leaving you with a belly button as a souvenir. Whether it’s an “innie” or an “outie,” we all have one !

Role of science in making india

In the last few years, science has helped a lot in the development of India. Science has contributed to all the sectors. Science has improved the global economy, increased employment opportunities, saved millions of lives and has played a major role in a lot of industries. Science is very important for the growth and development of India. It even plays a key role in our daily lives. Every country should invest as much as possible in research and development for scientific technologies. In this essay on the role of science in making India we will see how science has helped India to grow in different sectors.

How Indian Scientists have Helped India Grow?

When it comes to Indian Scientists, the first name comes to my mind is CV Raman. CV Raman was the first Asian who won the Nobel Prize. His work was related to light and sound. He investigated that when light passes through a transparent material, some of the deflected light waves see the change in its amplitude and wavelength.

APJ Abdul Kalam is the second name that comes in my mind in Indian Scientists. APJ Abdul Kalam worked as an Aerospace engineer with ISRO and DRDO. He was also president of India from 2002 to 2007. Abdul Kalam contributed a lot to Aerospace. One of the contributions is deploying Rohini Satellite near Earth’s orbit. A few more names are Homi Bhabha, Visvesvaraya, V Radhakrishnan, Satyendra Nath Bose and many more…

Seven Defining S&T Contributions That Have Impacted Every Indian - The India Saga

How has Science Increased Employment Opportunities?

Whenever any new technology is discovered it leads to new industries. For example, if any new scientific device is invented it will require eligible professionals to control the device. Such inventions help in increasing employment opportunities. This also helps in growth in many businesses which in turn develops the Indian economy.

Curing Diseases and Saving Lives

In the last few years, medical science has evolved so much and saved billions of lives. New technologies like wireless brain sensors, artificial organs, smart inhalers, robotic surgery, virtual reality are making work easier for thousands of doctors around the world. And also these technologies are saving millions of lives and curing diseases.

Role in Agriculture Sector

Science has played a very major role in the Agriculture sector. Food is one of the basic needs of our lives. And science has now invented so many new agriculture techniques which have increased production drastically. The old mundane techniques farmers used to follow was very slow, expensive, and required too much effort.

National Technology Day 2021: Science and technology for a sustainable future - The Financial Express

Science has made everything a lot easier for farmers. Improved facilities in irrigation, modern fertilizers, advanced equipment, and pesticides are all helping farmers to work faster, and save more money.

Conclusion

Science has helped us a lot in many ways and it will keep helping. Everyone should not only invest as much as possible in science and technology but also should stay aware of all new technologies developed around the world.

Some Unheard Phobias

Eisoptrophobia

Eisoptrophobia is the fear of mirrors. People having this phobia cannot look at themselves in the mirrors or any other reflective surfaces.

Xanthophobia

Xanthophobia is the fear of yellow colour. People having this phobia seems to get terrified seeing a yellow colour flower or a school bus and many more such yellow coloured things. They always try to avoid seeing the colour yellow at all costs.

Arachibutyrophobia

Arachibutyrophobia is the fear of sticking peanut butter sticking to the roof of your mouth. People having this fear avoid eating peanut butter in any form.

Globophobia

Globophobia is the fear of balloons. People having this phobia tend to run away even at the sight of a balloon.

Anemophobia

Anemophobia is the fear of winds. People having this phobia gets triggered by air vents and even hair dryers.

Ablutophobia

How is blue light affecting us?

Pandemic has made today’s world a 100% digital world. With digitalisation on the peak so, is our daily digital gadget usage. We are spending; 7-10 hours behind a screen doing our work, attending online classes or Netflix and chilling. While doing so, we are exposing ourselves to harmful blue light radiated from these digital gadgets.

This blue light is causing eye strain and sleep deprivation in most of us.

Why blue light radiation causes eye strain?

The reason is when someone is exposed to the blue light coming from laptop screens or mobile screens they tend to blink fewer times than usual. This causes eye strain resulting in discomfort in the eyes. Blue light has the shortest wavelength and the highest frequency. So when it enters the eyes it causes much more scattering than any other light. This causes glare disability and discomfort glare at low intensities.

Blue light causes difficulty in falling asleep

Blue light exposure disturbs the circadian rhythm of the human body. In the olden days, the only source of blue light exposure was during the daylight hours and when the night falls, the body automatically signals the body to sleep by secreting melatonin. But due to the exposure to blue light, this melatonin secretion is suppressed and it thus affects the sleeping pattern.

Some of the best ways to prevent this blue light exposure is by reducing the screen time, using a blue light filter app on your gadget, wearing spectacles with blue light filter and using the 20-20 rule where you work on the screen for 20 minutes and then take a 20 minutes no gadget break.

Why do we look different in photos?

No wonder we always experience that how hard we try to click a good photo for our profile picture, it is so hard for all of us to get a decent photo.

Also, when we look ourselves in the mirror we look just fine! Then why exactly we look good in mirror but bad in photos?

Reality is we do not really know how we look. The mirror gives us a reflection and the camera does not show us our accurate face.

The mirror we look in all day during brushing or combing or before going out, makes us believe that this is how we look. We are so accustomed to see ourselves in mirror that when we see ourselves in a picture we are unable to recognize ourselves.

Mirror shows us the enantiomorph version of our face in simpler terms when we see in a mirror the right becomes left and the left becomes right, and so unless you have a 100% symmetrical face, you will always find slight change in the mirror image of you and photo clicked image of you.

Scientist call this familiarity MERE EXPOSURE. This mere exposure makes us favorable to things which are familiar and unfavorable to things which are unfamiliar. Henceforth, we are more inclined towards our mirror image than the camera clicked image. We somehow find that the mirror image is good looking than the camera image.

Also, the camera pictures we see are not true image. Camera clicks 2D images and thus it somehow distorts our real look.

Putting in a nutshell, we do not really know how we look and honestly it does not even matter how we look as Margaret Hungerford says beauty lies in the eye of the beholder.

Is science a boon or bane?

We are within the age of science and technology. Man cannot live without the help of science. Science has engulfed our lives that nothing can happen in our day o day work without the assistance of science. Our food, transport, learning, administration, recreation, and social life are linked with science in various ways.

To answer the question, whether science has come to mankind as a boon or because of the reason for ruin. one should know what science actually means. Science is claimed to be a scientific classification of experiences. We, men, wonder at the varied thing and events happening around us. We get doubts about what are they? why are they happening? If so why these questions are the fundamental seats of science. then starts with thinking, analyzing, reasoning, synthesis, and contrast, and at last, the reality reveals. scientists say there’s a methodology for everything and there are inevitable steps to follow, they include, observation, hypothesis, experiment, theory, and proofs. all scientists having the way followed these steps.

Aim of science:

The aim of science is to go looking for truth and to grasp things, hitherto unknown. A scientist doesn’t accept ideas, just because they were accepted by others earlier. Great discoveries are a result of reasoning. lots of patience and observation are required. Civilization, because it today, is that the result of a variety of discoveries made within the field or of science. The invention of the easy wheel has resulted in our modern industrialization. Electricity, as a source of energy, has revolutionized the planet. Science has contributed to the success of our revolution and now we’ve enough food for all. we’ve enough clothing and better shelter too. All this can be possible, only because of science. Radios, television, and cinemas that entertain us are the products of science. So as a standard man must conclude that science is boon to mankind.

There is another side of the coin too, where such gave science which gave birth to destructive weapons like guns, rifles, rockets, atom bombs, hydrogen bombs, etc. It’s the science that has electric power and nuclear energy, hydroelectric power but atomic energy isn’t used for peaceful purposes, like Hiroshima and Nagasaki which happened as a result of science, it’s the bane of humanity.

Leaving that apart, another creation of science is that the pollution of the environment. Industrialization with the help of science has polluted air, food, and every one of the atmosphere. The ozonosphere is giving threatening signals. so here is the case for a person to contemplate science as a bane.

A human could be a rational being. to safeguard themselves against all odds. that’s how he was able to conquer and control all the creatures within the world. So allow us to believe that his wisdom will prevail and he would conclude for the well-being of his kind on this planet.

When the universe reveals more secrets to humans by means of science, there’s hope that this man will become a superman and eventually science would be only a boon and not a bane of his life. Science without conscience is that the death of the soul.

AIR IN SPACE ( FICTION )

AIR EVERYWHERE

Air is the critical building block for sustained life on a planet, but with a combination consisting of various gases that we commonly call it has to Air. For example, Nitrogen 78%, Oxygen 28%, Other gases like Neon, Carbon Dioxide, Hydrogen, Xenon, Argon, Krypton, Helium, and others add up a total of 1%. This a type of combination of Air which our lungs are used to.

But what about Space, which is a giant vacuum area where all the living things do not exist. If an event occurs in the Space due to which this empty area with vacuum gets starts slowly filling with air. What will then happen after?

The changes which we may first face could be as follows:

1. We could hear the supernovae (stars) explosion sounds without specialized equipment because sound can travel through the air. Still, there’s a catch to listen to the sound we must closer to the object, almost impossible supernovas are very big with immense temperatures.

2. The other effect could destroy life from our planet, which will happen due to friction.

3. After the presence of air outside our planet and its surroundings, it may increase our planet’s atmospheric pressure. It is leading to the crush of all living beings in just a few hours.

4. Then the moon will start to come closer due to friction, leading to a slowing of the rotational speed of earth, and then eventually stop, and their orbits will change.

5. Eventually, the temperatures will rise due to increasing atmospheric pressure; after some time, the earth with the moon will submerge into the sun.

6. Other effects of this situation will turn gaseous planets like Jupiter and Saturn into bright stars due to air and pressure.

How a PURPLE DYE changed the world

In the year 1800s, purple color was used to be a sign of wealth, richness & being elite. Only people of royal families were the ones who wore purple-coloured clothes, common people were abolished and even punished if they even dared to wear purple-coloured clothes. Queen Elizabeth I passed orders saying that only close members of royal families can wear purple. Hence, there was a huge discrimination between the common families and the royal families.

This was because, at that time purple dye was extracted from sea snails and there was no other natural resource for extraction of purple dye. These sea snails have special glands called hypobranchial glands for production ink and mucous. The shell of these sea snails was broken and these special glands were taken out and oxidized to produced purple. The dye obtained after killing so many sea snails was really less comparatively and the whole process may sound easy but was really exhaustive also, there was an awful smell produced when all these procedures were conducted in real. All these things added up making purple dye an expensive commodity like gold and diamond today.

The second part of this story takes place when in the year 1860s there was a wide spread of malaria in the Britain and to treat malaria quinine was needed. Quinine at that time was only grown in South Africa and the British Government had to spend a lot of their asset to buy and transport quinine from South Africa to Britain. Hence, the British Government passed orders saying that whoever will produce synthetic quinine in Britain will get rewarded. All the scientists at that time started working in laboratories day and night to produce synthetic quinine.

One of the scientists of that time William Henry Perkin who was 19-year-old, was also working in a laboratory doing experiments to produce synthetic quinine, but he was miserably failing and was not getting a futile result.

One fine day, he again tried doing his experiments using crude and aniline and accidently something black in color was formed in the bottom of his test tube. He then tried to wash his test using water but the black substance was not cleaning out he then tried using alcohol. The result changed the history, when he added alcohol to the test tube the product in the test tube turned purple.

William, then realized he can sell his purple color as synthetic purple dye. William’s dye has now become the color of century. The color has opened many frontiers, William has now become one of the richest man of his time, the bridge between the rich and the poor was completely removed, his synthetic dye was the first ever made synthetic dye and was a pioneer for biological discoveries also we cannot ignore the fact how his single experiment saved lives of thousands of snails.

And, that is how a purple dye changed the world.

IRON DOME THE SHIELD OF ISRAEL

IRON DOME PROTECTING ISRAEL LIKE WAKANDA-

Iron Dome is an effective, truck-towed, multi-mission mobile air defence system developed by Rafael Advanced Defence Systems. The system has been developed to counter very short-range rockets and 155mm artillery shell threats with ranges of up to 70km. It can be operated in all weather conditions including fog, dust storm, low clouds and rain.

The all-weather air defence system protects the population and critical assets and can be strategically placed to reduce collateral damage. Iron Dome detects, analyses and intercepts a range of incoming threats, including C-RAM, precise guided missiles, cruise missiles, unmanned aerial vehicles and air-breathing threats.

The system has so far intercepted more than 2,500 incoming targets with a success rate of over 90%.

Selected by the Israel Defence Ministry, Iron Dome provides defence against short-range missiles and rockets which pose a threat to the civilian population of Israel’s northern and southern border.

“In July 2010, the US House of Representatives approved $205m in funding to speed up the production and deployment of Iron Dome.”

The system was deployed by the Israeli Air Force (IAF) in March 2011.

In November 2012, Israel installed the fifth Iron Dome battery at Gush Dan in response to the rocket attacks on the Tel Aviv area. The Iron Dome air defence system is being used to intercept and shoot down hundreds of rockets from Gaza as the latest round of escalations between Israel and Palestine in May 2021 engulfed the region. The violent clashes saw Hamas launch a barrage of rockets targeting Tel Aviv in Israel in response to an alleged Israeli airstrike in Gaza. The death toll in the Gaza Strip as a result of the Israeli airstrikes stood at more than 60 people.

I-DOME is a mobile version of the system, which can be deployed on a single truck, while C-DOME is a naval version.

Iron Dome mobile air defence system background and development details

The firing of rockets by Hezbollah during 2006’s Second Lebanon War led to the development of Iron Dome. Nearly 4,000 rockets, mostly of the short-range Katyusha type, were fired on Haifa and other northern regions of Israel.

About 44 Israeli civilians were killed in the attack and approximately 250,000 citizens were evacuated and relocated to other parts of Israel.

Between 2000 and 2008, more than 4,000 mortars and 4,000 rockets (mostly Qassams) were fired from Gaza into southern Israel. As the range of the Qassam has been expanded due to the introduction of 122mm Grad launchers, nearly one million southern Israelis came within the range.

To counter the rocket threats, the Israel Defence Ministry decided in February 2007 to develop a mobile air defence system.

The missile defence system was successfully tested in March 2009. The testing was carried out without physically intercepting a missile or rocket. In July 2009, during a defence ministry test, the system successfully intercepted a number of rockets.

A new battalion was established by the IAF in August 2009 to operate the Iron Dome system. Multiple rocket bombardments mimicking Qassams and Katyushas were intercepted successfully in a test carried out in January 2010.

The final testing of the Iron Dome was undertaken in July 2010. The system successfully determined and intercepted only incoming missile threats, while other missiles which were headed toward open fields were not intercepted.

Raytheon collaborated with Rafael for the commercialisation of the Iron Dome weapon system in the US in August 2011. Raytheon secured a $149m contract from Rafael for the supply of Tamir interceptor components used in the system, in September 2014. It was formed as a new joint venture between Raytheon and Rafael in August 2020 to establish an Iron Dome production facility in the US.

THE DEADLY CORONA VIRUS AND ITS MECHANISM OF INFECTION

The word coronavirus and the virus itself has been hovering around each one of us since 2020. Its been more than a year and the human race, which is regarded as the owner of the most intelligent brain has been unsuccessful in finding a permanent solution to the ongoing global pandemic situation. But, do you know what is this tiny, invisible organism which has proven “deadly” to the most advanced and the most evolved body system on the earth? Yes, you are right, it’s a ‘virus’! So, today let us initiate a step forward to understand the mechanism of infection of the Covid-19 virus.

MECHANISM OF MULTIPLICATION OF COVID-19

As soon as the virus comes in contact with a human cell, the receptors present on the surface of the human cell attach to the virus. ( These Receptors have an affinity towards a specific kind of molecule or a virus). The coronavirus binds to these receptors following the introduction of the viral RNA into the normal human cell. The viral RNA thus undergoes reverse transcription (the process of formation of DNA from RNA) which leads to the incorporation of the viral DNA into the host genome( human cell). The infected human cell undergoes its normal processes and along with its own RNA, it also produces a new viral RNA which finally leads to the further multiplication of the virus which in turn are ready to infect other cells .

This is the complex mechanism of the multiplication of the Covid-19 virus. The virus directly attacks your lung cells and makes the respiratory system completely dysfunctional.

Therefore, it is very crucial to block the entry of the virus itself using masks and avoiding touch of infected surfaces. Remember, the number of people getting infected or the number of deaths are not just numbers, they are the families who spend each minute of their lives in tears with burning hearts. Save yourself, save your family.

Science

Science is the systematic study of observations in order to acquire knowledge and forming empirical methods about the physical and biological world. Earlier in pre-scientific times, people were more likely to believe in magical and supernatural explanations for natural phenomena like eclipses, earthquakes, thunderstorms, etc. By contrast, scientifically minded people looked out for reasons to figure out the natural world through testing and observation. But Skeptics often question, why science can’t explain all the natural phenomena happening around the world? But, we need to keep it in mind that science is not magic, it couldn’t solve humanity’s problems but sure is the most powerful method for acquiring knowledge about the observable universe. Some of the essential elements of science are-

Systematic observation- Scientists observe, record, and measure the data systematically. Recording the data is necessary so that our memory biases are not able to creep in.
Observations lead to hypothesis- Hypothesis and theories are such to be stated that they could be tested. Extraordinary claims require extraordinary pieces of evidence.
Democratic- Nowadays science has gone democratic, earlier people were willing to accept the views of their kings, pharaohs, or priests. But itis not so, nowadays it doesn’t matter how reputable one is if their theories do not conform to the data, it is invalid. Earlier scientists like Copernicus, Galileo faced discrimination, because of the autocracy of the priests of the church.
Cumulative- Science is cumulative. Today a physics student or chemistry would know more than Newton, Rutherford could ever know, despite being eminent scientists of their time. This is so because we learn from earlier advances, so as to build on them and move farther along the path of knowledge.
Relevant- It is related to reality rather than floating in space.
Consistent- Science is consistent. It has consequences, answers relevant questions, and pursues promising leads.

There are many people who have made substantial positive contributions to humanity in modern times. Exempli Gratia, Dr. Edward Jenner, often considered the father of immunology since he was first to conceive of and test vaccines. His pioneering work led directly to the eradication of smallpox. Fritz Haber and Norman Borlaug created The Green revolution by producing hybrid agricultural crops and synthetic fertilizers due to which we are able to meet the needs of seven billion people on people. The starvation caused is due to the political and economic factors rather our collective ability to produce food. Earlier there were fewer cars, telephones, refrigeration or electricity but now tables have just turned. 80% of the population has televisions, 84% have access to electricity all thanks to the scientific community and their inventions. Average life expectancy has substantially increased from 47 years in the 90s to 75+ years in the contemporary world. Even average IQ has also been increased due to better schooling and nutrition. All these advances are going to continue, there would be no saturation in the foreseeable future. In a civilized society democracy is prevalent in every field, be it science or any other. Therefore people should be able to take criticism and not be ignorant and contribute most to the society rather than blindly following rituals that have been there for ages.

It won’t be tangible to talk about all the feats of science in such a short space and time. Science is vast than we could imagine, therefore we should introspect into our lives and look for ways in which we can contribute to it.

After Beirut, alert out for ammonium nitrate, TN stockpile on radar

A 740-tonne consignment of ammonium nitrate lying at a Chennai port Customs warehouse since September 2015 has set alarm bells ringing after Tuesday’s catastrophic Beirut blast. An estimated 2,750-tonne stockpile of ammonium nitrate, stored reportedly for six years in a port warehouse, blew up killing over 100, injured over 5,000 and ravaged the Lebanese capital city.

Referring to this blast in a note, the Central Board of Indirect Taxes and Customs (CBIC) has “urgently directed” Customs and its field formations to “immediately verify and confirm within 48 hours that any hazardous and explosive material lying in warehouses and ports across the country meets all safety and fire standards and presents no danger to life and property.” After the Beirut blast, the Chennai stockpile, sources said, was the red flag for the alert. A senior Customs official said that “ways to shift out the ammonium nitrate at the earliest” are being explored.

“There’s some difficulty in taking action keeping safety regulations in mind. We are going through details. The e-auction will be conducted as per law…like for any other confiscated or seized goods or goods which are lying for a long time,” the official told The Indian Express.

The stockpile at Chennai port relates to a case involving the seizure of an import consignment of Karur-based Sri Amman Chemicals five years ago. The company had, in September 2015, filed for Customs clearance for the chemical packed in 37 containers, with the declared assessable value of Rs 1.80 crore claiming for use as fertiliser inputs.

The company claimed it had the required licence for the import while Customs authorities alleged misclassification and resultant evasion of duty after which the Madras High Court, in November 2019, ruled in favour of Customs authorities.

Result: the ammonium nitrate consignment continues to be stocked with Customs.

In a tweet Thursday PMK leader S .Ramadoss flagged this: “There is a risk of a similar explosion due to ammonium nitrate in the Chennai warehouse. To prevent this, the ammonium nitrate explosive substance in the warehouse should be safely disposed of and used for other purposes such as composting.”

In a statement Thursday evening, Chennai Customs said that the seized cargo is at a container freight station at Manali, 20 km from the city with no residential locality within 2 km. “The seized cargo is securely stored and safety of the cargo and the public is ensured considering the hazardous nature of the cargo…the disposal of the said cargo will be done within a short period, following all safety measures,” it said.

The Central government had, in July 2011, declared ammonium nitrate as an explosive under the Explosive Act, 1884, after which the CBIC issued Ammonium Nitrate Rules, 2012, for its import/export.

AMMONIUM NITRATE:

Import of ammonium nitrate — or any combination containing more than 45 per cent of ammonium nitrate by weight — including emulsions, suspensions, melts or gels (with or without inorganic nitrates), and classified under Explosives Act, 1884, is subject to license from Chief Controller of Explosives.

In the Chennai case, Customs said the company had just a P-3 licence for possession and sale of 1000 tonnes of the chemical but not the P-5 licence it needed for its import. Customs authorities also alleged that some actual users/firms to whom Sri Amman Chemicals sold ammonium nitrate were explosive dealers.

Queries e-mailed to Sri Amman Chemicals did not elicit a response.

In its petition in the Madras High Court, the company said that it had applied to the Chief Controller of Explosives, Petroleum & Explosives Safety Organisation (PESO) for a P3 licence which it got in December 2014.

It applied to PESO for a P5 licence in August 5, 2015. The company claimed that PESO, without putting it on notice or hearing its view, passed an order on August 19, 2015 rejecting its application but by then, the 740 metric tonnes of ammonium nitrate had already arrived at Chennai.

In its order, the court referred to explosions in various parts of the country in which ammonium nitrate was a common ingredient. It noted that as per the police, over four years since 2013, nearly 16,000 tonnes of ammonium nitrate went missing. The Court ruled that accumulating smaller quantities of ammonium nitrate would result in gathering larger quantities in the hands of “unknown and unidentifiable” persons and such trade would not be in interest of national security, adding that the authorities rightly rejected the claim of the company for a P5 licence.

Ammonium Nitrate is not an explosive by itself but is one of the ingredients used for manufacture of explosives. It is classified as an oxidizer as per UN classification for Dangerous Goods. Other ingredients like fuel, etc., have to be added to make it an explosive and for such explosive mixtures to explode, initiators like detonators are required.

Cyclone

Cyclonic storm is caused by atmospheric disturbances around a low-pressure area and is usually accompanied by violent storms and severe weather conditions. Cyclone is derived from the greek word cyclos – coiling of snake. Tropical Cyclone is a deep low pressure area from around the center the strong winds, spirals and pick up the speeds of 62 kmph or more. In Northern hemisphere these winds rotate counter clock wise and in Southern hemisphere clockwise. The tropical cyclones that are intense are known as huricanes Over the Atlantic Ocean and typhoons over the pacific ocean. They are know by different names for example dust devils, supercell thunderstorm, tomadoes, tropical cyclones, extra tropical cyclones etc. On the basis of the speed of the wind cyclones are classified into 5 different categories.

According to the category of the cyclone the wind speed varies that is from 60 km an hour to about 220 kmph and above. When the speed of the wind around the low pressure area reach upto 60 kmph it is known as tropical cyclone and the name is assigned. When wind speed settles between 89 and 118 kmph, it turns into a severe Cyclonic storm. When wind blows at a speed of about 119 to 221 kmph then it is known as very severe Cyclonic storm and when the speed of the wind exceeds 221kmph then the cyclone is known as supercyclonic storm. The word meteorological organization (WMO) has a well defined process to select the name of each cyclone.

A cyclone named fani is a massive Cyclonic formation over the south of bay of Bengal which made landfall in odisha.

Cyclone like ookhi hit parts of kerala, tamil nadu, sri lanka, and maldives at 185kmph with total fatalities of 245 in kerala that time around 80 fisherman were killed and 140 people were reported missing. In 2018 cyclone gaja also made landfall in Nagapattinam ‘s vedaranyam block and killed around 46 people. In 2019 vayu in the Arabian Sea.

The polar vortex is a large area of low pressure and cold air surrounding the Earth’s North and South poles in each Hemisphere. The term refers to the counter clockwise flow of air that helps the colder air close to the poles. Often during winter in the Northern hemisphere the polar vortex will become less stable and expand senting cold artic air southward over the East of US with the jet stream. One exist in the troposphere where we live and where the weather happens. The other exists in the second lowest, called the stratosphere, which is a shroud of thin air that gets warmer at higher altitudes. The tropospheric polar vortex is the one that affects our weather with piercing shots of cold, intense bouts of storminous and bitter wind chills reaching upto 80°Celsius.

Crystallography

The International Union Crystallography (IUCr) and UNESCO has jointly organized 2014 as International year of crystallography. With this they aim to promote education and public awareness through a variety of activities and to broaden the base of crystallography, in order to provide developing countries with more expertise in this field which can be made use in their scientific and industrial development.

Crystals are all around us. Most of the time, we do not even realize all the crystals we see in our day to day life. Now, let’s see they are. Crystals are solids that are formed by a regular repeated pattern of molecules connecting together. Throughout history, people have been fascinated by the beauty and mystery of crystals. Sugar grains, ice, salt, gemstones, graphite etc are crystals that we see around us. Diamond is one of the simplest and most symmetrical of crystal structures.

CRYSTALLOGRAPHY is the science that examines the arrangement of atoms and solids in a crystal. Crystallography supports the development of all new materials, from every day products like computer memory cards to flat television screens, cars, aeroplane components and liquid crystal display devices. In fact crystallography has many applications. It touches our everyday life and forms the backbone of industries including agro-food, aeronautic, automobile, beauty care, computer, electro-mechanical, pharmaceutical, and mining industries.

In the 20th century it was realized that X-rays could be used to see the structure of matter. This marks the dawn of modern crystallography. X-ray crystallography has been the main method of determining the atomic structure of minerals and metals since 1920.Everything we know about rocks, geological formations, the history of earth, knowledge of meteorites comes is based on crystallography. Drug design depends on the use of crystallography. Knowing the precise shape of the protein allows the scientists to design drug compounds that can stick in to the active sites on the protein and thereby disable the harmful activity. Crystallography is essential at the stage of drug manufacture. It is used in the quality control of the processed drug during mass production, to ensure that strict health and safety guidelines are met.

NASA’s Perseverance Rover Launched on Ambitious Mission to Mars

NASA’s Mars 2020 Perseverance rover lifts off from Cape Canaveral on july 30,2020.Also the rocket provided by United Launch Alliance is the technology experiment Ingenuity Mars Helicopter

Perseverance is a Mars rover manufactured by the Jet Propulsion Laboratory for use in NASA‘s Mars 2020 mission. Nearly identical in design to the Curiosity rover, Perseverance will carry seven scientific instruments to study the Martian surface at Jezero crater, 23 cameras in total, and two microphones. The rover will also be accompanied by the helicopter Ingenuity, which will help Perseverance to scout for locations to study.

ON THURSDAY MORNING, NASA launched its new Mars rover, Perseverance, on a six-month journey to the Red Planet. The car-sized rover was boosted into space atop a United Launch Alliance Atlas V rocket that departed from the Kennedy Space Center in Florida. It’s the third and final Mars mission to depart Earth this summer; earlier in July, China and the United Arab Emirates also launched their first Martian explorers.

Perseverance will enter the tenuous Martian atmosphere going more than 10,000 miles per hour, which means that as it slices through the air it will experience temperatures of nearly 4,000 degrees Fahrenheit. “The heat shield really takes the brunt of hitting the atmosphere,” says Tice of the lander’s protective structure. But if it works as it’s supposed to, inside its protective casing the rover and its sensitive equipment will never experience temperatures much warmer than a hot summer day in the desert. This is because the ablative heat shield dissipates heat as its layers are burned off.

If there was ever life on Mars, these samples may very well prove it. It would be a monumental discovery that would fundamentally change our understanding of life as we know it—and it all starts today.

Rafael aircraft coming to India from France

The Dassault Rafale is a French twin-engine, canard delta wing, multirole fighter aircraft designed and built by Dassault Aviation. Equipped with a wide range of weapons, the Rafale is intended to perform air supremacy, interdiction, aerial reconnaissance, ground support, in-depth strike, anti-ship strike, and nuclear deterrence missions. Many of the aircraft’s avionics and features, such as direct voice input, the RBE2 AA active electronically scanned array (AESA) radar, were domestically developed and produced for the Rafale program. Originally scheduled to enter service in 1996, the Rafale suffered significant delays due to post-Cold War budget cuts and changes in priorities. The aircraft is available in three main variants: Rafale C single-seat land-based version, Rafale B twin-seat land-based version, and Rafale M single-seat carrier-based version.

Rafel-piuja-390x220

The Rafale is being produced for both the French Air Force and for carrier-based operations in the French Navy. The Rafale has been marketed for export to several countries and was selected for purchase by the Indian Air Force, the Egyptian Air Force, and the Qatar Air Force. Due to its great capabilities, the first batch of 5 raflaes arrives in India in two days.

On the one hand, when there are neighbors like China and on the other hand, when there are neighboring countries like Pakistan, India needs to work on both its army and the Indian Air Force. In such a situation, 5 Rafale aircraft was given to the Indian Army yesterday. These Rafale aircraft flew from France yesterday and reached the UAE airbase Al Dhafra today. Here their maintenance and refueling work will be done. After this, these fighter aircraft will fly and arrive at Ambala Air Force Base tomorrow. With this aircraft joining the Indian Air Force, the morale of the Indian Army will be greatly elevated. However, the condition of the Airforce is not good right now because there is a shortage of squadron. This thing has been told in many reports. But with Rafael joining the Indian Army, it can play a decisive role in winning a war.

“You can call them (Rafale) both beauty and the beast,” said Indian Ambassador to France Jawed Ashraf after interacting with the IAF pilots at the airbase before they set off for India. “Delivery of 10 aircraft has been completed on schedule. Five will stay back in France for a training mission. The delivery of all 36 aircraft will be completed on schedule by the end of 2021,” the Indian embassy in Paris said in a statement. India and France signed a Euro 7.87-billion ( ₹59,000 crores approximately) deal on September 23, 2016, for 36 Rafale jets. The IAF official said the air-to-air refueling of the aircraft will be undertaken with dedicated tanker support from the French Air Force. “Our air force pilots tell us that these are extremely swift, nimble, versatile, and very deadly aircraft,” said Ashraf while congratulating the IAF pilots on becoming the first ones to fly one of the world’s most advanced fighter aircraft. The envoy thanked Dassault Aviation, the manufacturer of the aircraft, for delivering the fleet on time, the French government and the French Air Force for extending all required support.

Lockdowns And Decreased Seismic Noise

Scientists from the Royal Observatory of Belgium in Brussels recently shared an observation that after lockdowns were imposed by governments all over the world due to the COVID-19 pandemic, there has been a remarkable decline in human-linked vibrations within the crust of the Earth. And the scientists in Brussels, with the help of other scientists around the world, have published a new study in the journal “SCIENCE“, which shows how the ‘Seismic Noise’ has reduced, allowing them to observe and record previously concealed earthquakes better.

Measured using seismometers, seismic waves are the vibrations traveling within the Earth that could be set off by earthquakes or volcanoes. The waves could be subject to the disturbance caused due to human activities or naturally. In the study, it is found that the reduced human activity led to an average drop of around 50% human-caused seismic noise, which was recorded between March 2020 to May 2020. The drops in the seismic noise, especially in the urban areas, are unprecedented and are observed to be more than what is considered usual quiet periods like weekends, holidays, or during the night.

The scientists have termed this time of global anthropogenic or human-based seismic noise deduction as ‘Anthropause’. This anthropause can help the scientists get a more accurate measure of the seismic waves and to differentiate between human and natural seismic noise clearly.

Lead author of the study, Dr. Thomas Lecocq from the Royal Observatory of Belgium explains, “With increasing urbanization and growing global populations, more people will be living in geologically hazardous areas. It will, therefore, become more important than ever to differentiate between natural and human-caused noise so that we can ‘listen in’ and better monitor the ground movements beneath our feet.”

The scientists and researchers are hoping to move forward with their study of seismic lockdown and the previously hidden indications of earthquakes and volcanoes would be easier to be recognized and there will be a better understanding of the natural seismic waves.

SOLID WASTE MANAGEMENT – A CHALLENGE

Before the arrival of motorized transport horse drawn traffic was the main stay of all major cities. In Newyork alone there were more than 100000 horses which produced more than a million kilo of horse manure which had no system for disposal. Millions of flies bred on this manure creating yet another urban public health issue. The problem was faced by cities after cities around the world. But there was no solution.

Urban solid waste management remains a challenge around the world even now. Cities big and small, from countries developed and developing face major challenges in dealing with waste management.

Anything which is solid and is considered by its owner to be not worthy of continued use become a solid waste. The composition of the solid waste varies vastly depending upon the economic situation of a society while used automobiles and white goods are a major component of urban solid waste in developed countries. The culture of repair, reuse, and recycling in developing countries ensures that these do not end up in the waste piles.

Solid waste can be classified into seven

1.Household solid waste

2.Agricultural solid waste

3.Industrial solid waste

4.Waste from ships and Aircrafts

5.Hospital waste

6.Demolition of debris

7.Waste created by conflicts and disasters

US Environmental Protection Agency (EPA)hazardous waste is waste that is dangerous to our health or the environment. The following waste are often considered hazardous.

1.Industrial chemicals

2.Pesticides

3.Waste from oil Industry

4.Batteries and fluorescent lamps

5.Medical waste

6.Radioactive waste

7.Discarded pharmaceutical products

8.Discarded asbestos

9.Mixed Waste

In the last century Reduction, Reuse and Recycle (3R approach) reached significance. There are some global issues in waste management that is Trans boundary movement of waste, Technology transfer for waste management and disappearing land fills and it goes on……..

AstraZeneca COVID-19 vaccine

The initial trial data for the COVID-19 vaccine that has been developed in a joint collaboration between Oxford University and AstraZeneca. The data has been widely awaited as the world looks forward to some good news on the front of a vaccine that could shield people from the deadly coronavirus outbreak that has already infected over 14 million people worldwide and killed over 6 lakh.

The potential vaccine is already in large-scale Phase III human trials to assess whether it can protect against COVID-19, but its developers have yet to report Phase I results which would show whether it is safe and whether or not it induces an immune response. The developers of the vaccine said this month they were encouraged by the immune response they had seen in trials so far and were expecting to publish Phase 1 data by the end of July.

How does the Oxford-AstraZeneca vaccine candidate work?

When someone is infected with the Covid-19 virus (SARS-CoV-2), the reason it spreads in the body easily is because of the spikes on its surface. These spikes, known as the ‘spike protein’, allow the virus to penetrate cells and, thereafter, multiply. The vaccine developed by Oxford and AstraZeneca, which belongs to a category called non-replicating viral vector vaccines, tries to build the body’s immunity against this spike protein. The idea is to create antibodies to fight this spiked surface so that the virus does not even have the chance to penetrate the cells. The vaccine uses a different virus — in this case, a weakened version of a common cold virus (adenovirus) that infects chimpanzees — to carry just the code to make the spike protein, like a Trojan horse. The adenovirus, genetically modified so that it cannot replicate in humans, will enter the cell and release the code to make only the spike protein. The body’s immune system is expected to recognize the spike protein as a potentially harmful foreign substance and starts building antibodies against it. Once immunity is built, the antibodies will attack the real virus if it tries to infect the body.

Since the Covid-19 vaccine has been developed by a United Kingdom-funded university, UK will have intellectual property rights. Other countries such as India will need to enter into commercial deals or understanding via foundations such as Coalition for Epidemic Preparedness Innovations (CEPI) and Global Alliance for Vaccines and Immunization (GAVI). AstraZeneca also entered a deal with the Pune-based Serum Institute of India to supply one billion doses for low-and-middle-Income countries, with the first 400 million nicely before the end of 2020. It is not yet clear how many doses India will be able to land at first since the rollout of the vaccine will be subject to considerations that are commercial as well as that of equity. The World Health Organization’s chief scientist has described the Oxford vaccine as the leading candidate in a global race to halt the coronavirus pandemic that has killed more than 600,000 people. More than 100 vaccines are being developed and tested around the world to try to stop the coronavirus pandemic, which has killed more than 600,000 people and ravaged the global economy.

SCIENCE & TECHNOLOGY : BOON ??

As we know that science & technology have filled our life with too many wonders…this has made our life so easy & fast…..from bullock cart to aeroplane….from postman to message….it has changed everything….. but as we know that every coin has two sides….
Science & technology have so many disadvantages also either it is related to health,privacy & security,emotional disturbance or it is related to nature..

according to the America’s optometric association the more use of computer, laptop, phone is the cause of eye strain and dry eye.

According to national cancer institute over use of phone can be the result of brain cancer.
2.4% of deaths are caused by using phone during driving…

from the negative impact of science & technology children and teen s are affected very badly….according to the times of India a 16 year old boy get suffered by cardiac arrest while playing PUBG…from so many previous newses we get to know that don’t know how many children get affected by THE BLUE WHALE GAME …because of this don’t know how many children committed suicide and don’t know how many children got depressed….

when the tech was launch in to the market then who thought that which type of days it will going to see us …..let’s take a real life example…EK TIME THA JAB BACCHE APNA HOME WORK GURU KI MADAD SE POORA KARTE THE OR AB BACCHE GURU KI MADAD SE NAHI GOOGLE KI MADAD SE APNA HOME WORK KRTE HAIN………because of this their thinking power is going to be less and they are not using their mind fully to do any task!!!!!

There was a time when people used to say that BOOKS ARE OUR REAL FRIEND… but in today’s scenario people say that PHONE IS OUR REAL FRIEND…..
Science & technology even though has decreased the geographical distance but it has increase the distance of people’s heart’s…..and its example is SOCIAL MEDIA…..which provides us the facility to connect with every one wither we know them or not…we meet our new friends or old friends everyday on this platform…we also get connect here with our relatives….but this platform also interrupts in our personal life….according to research those persons who use social media a lot they feel more isolated in the society…..so here we can say that APNO SE JUDNE KI WAJAH SE APNO SE HI DOOR HOTE JA RAHE HAIN……

science & technology not only affected the beauty of relations it has also ruined the NATURE’S BEAUTY….just think who had thought hat we have to BUY OXYGEN ONE DAY…..it’s living example is our country’s capital DELHI…..there is a oxybar named as OXYPURE.. the high use of tech not only affect the humans it is also harmful for the animals , plants , birds and for every thing in this world …..climate change is also the result of over use of technology. Because of science & technology our privacy is also get affected….there are some apps who requires the accessibility of our location, identity, contacts, messages……with the help of this they can misuse the data also and they are doing this we can see this in today’ situation….there are some people who shared just everything on social media an this can be cause of trouble for them….as we have seen that rates cyber crime and theft of data are increasing day by day….and which can be very harmful for the future….there are some words of poet about tech…
24 HAATHON WALA LAGTA MUJHKO YE AVATAR..
12 HAATHON MEIN HAI SURGEON, 12 MEIN HATHIYAAR…

In reality if science & tech have given the eyes to a blind person then it is the science who made the person blind by the blue strain light (which comes from phone)…..if the science & technology have given the legs to a handicapped then it is the science who made the the person handicapped who drives during calls..if science & technology have given the power of hear to a deaf…then it is the science who made a person deaf with highly use of earphones..in reality science & technology is not a good or bad thong…it depends on us…it depends on it’s user’s intentions…the tech was invented to make the human life easier we invented it to make complete our tasks fast..we invented it to use it as a servant but in today’s scenario…..WE HAVE BECOME THE SERVANT OF THIS….so from now TREAT THE TECHNOLOGY AS A SERVANT OF YOURS NOT AS YOUR BOSS ……

The right use of science & technology and in the right direction can make the earn heaven and with the over and wrong use of it can make the earth hell….

over use of anything is always dangerous here are some lines of a poet

ATI KA BHALA NA BOLNA, ATI KI BHALI NA DHOOP…
ATI KA BHALA NA BARSANA, ATI KI BHALI NA CHOOP…

SO CHOICE IS OURS …IF GOD HAS GIVEN US A BEAUTIFUL HOME TO LIVE THEN IT IS OUR RESPONSIBILITY THAT WE SHOULD LIVE IN IT AS A RESPONSIBLE PERSON AND AMONG THE CREATIONS OF GOD ONLY HUMAN HAS MIND AND POWER TO DO SOMETHING AND HERE OUR RESPONSIBILITY INCREASES THAT WE SHOULD MAKE THE EARTH MORE BEAUTIFUL MORE THAN BEFORE…….

BLUIS (Bhubaneswar Land Use Intelligence System)

The Bhubaneswar Land Use Intelligence System is a geo-tagged repository that would monitor and detect all government lands in Bhubaneswar. This will be done by using high-resolution satellite imagery. For safeguarding government lands from encroachments by land grabbers- the launch of BLUIS makes Odisha the first state in the country to use satellite technology and artificial intelligence. Any attempt to change the use of government land in Bhubaneswar, BLUIS will raise alarm and guide the enforcement staff to the exact location of encroachment. ‘BLUIS’ and ‘Litigation Management System’ are among the 8 Technology-driven Solutions that were launched under the 5T initiatives by the Chief Minister.

Odisha-CM-Naveen-Patnaik-launches-BLUIS

Chief Minister Naveen Patnaik on 8 July 2020 unveiled BLUIS which would monitor changes in all government lands in Bhubaneswar by leveraging high-resolution satellite imagery. Along with that, he launched 8 technology-driven solutions under 5T initiatives for Home and GA & PG Departments through video conferencing. Along with BLUIS, the chief minister launched applications like e-Pravesh, e-Bhawan, e-Atithi, HRMS 2.0, HRMS mobile app, LMS 2.0, ORTPSA to improve public services. The 5T Initiative (Technology, Transparency, Teamwork, and Time Leading to Transformation) model of governance, launched in August 2019, requires each department of the State Government to draw up an annual work-plan for faster, better public service delivery systems leading to achieve transformational goals. Launching the services, Patnaik said that the 5T model of governance along with Mo Sarkar has brought about a perceptible improvement in the quality of governance and has eased the delivery of public services.

Encroachment of government land in the capital city of Bhubaneswar will no more be easy for land grabbers as the Bhubaneswar Land Use Intelligence System (BLUIS), a web and mobile-based solution, launched by Odisha government would raise alarm over attempts to change the land use. According to the government, BLUIS is a geo-tagged repository of all the government lands in Bhubaneswar, created through high-resolution satellite imagery to detect all changes taking place on government lands.

Odisha becomes the first state in India to use high-resolution satellite imagery utilizing space technology and artificial intelligence to monitor government lands. The lack of transparency and accountability of the enforcement in the current mechanisms and the increasing encroachment of government lands in Bhubaneswar resulted in the development of BLUIS.

“Bhubaneswar is one of the fastest-growing cities in India witnessing land-use changes on a daily basis. In the process, precious public land is prone to encroachment. The present mechanism of detection and enforcement lacks adequate transparency and accountability,” a senior officer said emphasizing real-time monitoring. A mobile application would alert the enforcement authorities of any new construction on government lands. The GPS on the application guides the enforcement staff to the exact location. Evidence of enforcement is uploaded on the application as geo-tagged images and videos,” he said. As per follow-up action, a case will be filed for removing encroachment. The Litigation Management System, an online application to record information on legal cases and enable end-to-end communication between government officials and advocates during different stages of a case, was also launched. It provides a smart technology solution to monitor court cases from initiation, online appointment scheduling, and allotment of the case to government advocate for preparation and submission of counter-affidavit.

Science and God

“Science” and “God”, the two words which are often seen as separate entities. These words seem conflicting to most of us and are often a topic of debate. Science seems to question the existence of God and believers of God often question why we are unable to explain the entire universe completely by science to date, a question on the success of science. We can often come across debates on televisions, radio, magazines, etc where people try to prove one as superior over the other. But, are they really two different things? Are they conflicting terms? Or are they same?

images

A deeper thought over it can clear our confusion. If we deep dig, we find that indeed both are the same. We really don’t need to choose between them. Science and God, are superior powers. The differences arise when we start associating God with some particular religion and Science with the only education. In reality, science is the process of thinking God’s thought after him. “An equation is really nothing unless it expresses a thought of God”, according to Ramanujan. They both actually merge at the spiritual level.

When we talk of science, it is the theories, the fundamental laws that very well explains the nature around us. It offers an explanation of all the natural phenomena in a very beautiful way and at a very basic level. It helped us understand how to converse in the language of nature, i.e in mathematics. It gives human power. The more we as humans understand science, the more powerful we become. Visit the days when humans started to understand science to get to know about the secrets of nature, the things they imagined then are now a reality. The gadgets they considered as their dreams are now in our hands. The technology we imagine today will also become a reality pretty soon. Science gave a power to humans to achieve the impossible.

God, on the other hand, is another superiority. There has been no proper evidence of someone seeing a God. We have not seen God, but we all believe in a “power” that is superior to all of us and many refer to this superior power as “God”. God gives humans the strength and power by making us understand the language of love and humanity. Spirituality is the heart of a human being and through God, we reach here. God helps us understand our potential and make us believe in our strengths. It changes our perception and makes the world a very beautiful and peaceful place for us. The world is incomplete without God.

1_9fct0mOWKz-9TZ_Q7Gky1w

We can thus conclude, that both Science and God are a source of immense power to human beings and both are tied together. Both speak the same language. The more faith we develop in God, the more we get close to science, the more we understand science, our belief in the existence of God becomes stronger. Louis Pasteur rightly said that “a bit of science can distance us from God, but more of it nears one to him”, and that is for sure. Diving deep into them will give us immense power and peace.

CHILDHOOD MEMORIES

It is generally said that we remember many of our misfortunes and on very few occasions only do we remember our joys. The recollection of the past normally appears to be sweet. Very often what gives one unhappiness at the moment it happens, may appear in a different light when thought of at a later date. It so happens that some feel that their past had been happy, in spite of many unfortunate or sorrowful incidents, or, disappointments. Similarly, others may feel that their past was not worth remembering so full of misfortunes it had been. In the same manner, such opinion ‘s may be held about our childhood.

A person may not like to remember his childhood days because they might have contained misfortunes or unpleasant experiences. At the beginning of life, a child is at the mercy of its parents. The child does not have any freedom of action or speech. Under the pretext that the child is prone to do mischief, others put it down and command implicit obedience from it. Sometimes, the child becomes the butt end of ridicule or punishment of even servants. When the child attains school – going age, he is under the control of teachers. In most of our schools children in the lower classes are expected to observe absolute silence. This breeds in them an inferiority or fear-complex. It is not generally understood by teachers in the lower classes that children should be given much freedom only retraining for themselves the privilege of controlling the children who might be wayward or mischievous, or when they tend to go beyond the limit of right conduct.

When such is the experiences of childhood, many persons may not like to think back upon those days. The bitterness felt in childhood is best be forgotten, they feel. It would be an unwelcome or bitter thing to bring back into the mind, the memory of unpleasant incidents or experiences and allow them to spoil the happiness of later life. In a country like India,where poverty ignorance and illiteracy dominate daily life, a child in the lower strata of life has to experience much misery. Each day of existence is one round of journey through hell. To add to these difficulties, if the surroundings and family circumstances are uncongenial, the child’s life may be absolutely intolerable and miserable. This child may in course of time be successful in life through a change of fortune or by dint of honest efforts at improvement, thus revealing a forceful character such cases, the person concerned may not like to remember childhood days. Indian Prime Minister Narendra Modi suffered a lot during his childhood days but now he became an inspirational character in History.

However, it cannot be said that childhood days are always bitter and to be forgotten in later life. There are children born with a silver spoon in their mouth. In a family, where discipline is given foremost importance or in a family in which children are brought up with strictness tempered with mercy and kindness, the child may have happy experiences. It may be treated with kindness and understanding and may get all advantages of good breeding and training. The memory of such a childhood would be sweet to one who rises to an eminent position or is reasonably happy later on in life. It may also so happen that one who had several advantages in early life turns out to be bad or goes astray as one grows up. This may be because such a person growing up with several advantages might not be aware of the pitfalls of life. Such people also might not like to think of their childhood.

Life however is not of one uniform quality. It is neither wholly happy nor wholly unhappy. It is a mixture of the good and the bad, virtue and vice, it has its rosy side as well as the seamy side. In the life of an individual childhood consists of both these aspects and therefore, the memory of childhood may not be entirely bitter or sweet. The natural tendency of human beings in such cases is to think more of sorrow than of the joys experienced. Sorrows and miseries and misfortunes leave an indelible mark on the humankind. When one looks at one’s life in retrospect, only these experiences come first to the mind. Joyful experiences find only a secondary place though at the time they happen, they afford pleasure and satisfaction.

A successful novelist like Charles Dickens gave greater importance to the sorrowful and more unfortunate aspects of life than to the good fortunes enjoyed by some of the characters in his novels like ‘David Copperfield’ and ‘Oliver Twist’. The life of these two characters might be said to be almost reflections of the novelist ‘s life or the mirror of the miserable life of society of the times. Very rarely do people remember the joys of the earlier period. It is such an idea that Shelley speaks of the lines, “Our sweetest songs are those that tell of the Saddest thoughts” – words full of wisdom and experience.

IISERs

Indian Institute of Science Education and Research (IISER) are public research institutes of India. These are the premier institutes of India. The institutes were established by the Government of India through the Ministry of Human Resource Development (MHRD) to provide quality college education in basic sciences coupled with a taste research at the undergraduate level itself. The institutes were formally established by the Parliament of India through the National Institutes of Technology, Science Education and Research (Amendment) Act, 2010 (an amendment to the National Institutes of Technology Act, 2007). Seven IISERs have been established across the country, namely IISER Kolkata in West Bengal, IISER Pune in Maharashtra, IISER Mohali in Punjab, IISER Bhopal in Madhya Pradesh, IISER Thiruvananthapuram in Kerala, IISER Tirupati in Andhra Pradesh, and IISER Berhampur in Odisha. The basic idea behind establishment of IISERs was to promote research-oriented training and to promote basic sciences. Indian Institute of Science, Bangalore and National Institute of Science Education and Research, Bhubaneswar has already been established to promote natural sciences but were not enough for a large country like India with enormous number of students having the potential to go ahead with research. All IISERs were declared as Institutes of National Importance by the Parliament of India in 2012, to promote them as leading institutions in the country in the field of basic sciences along with its sister institutes mentioned above.

T--IISER-Bhopal-India--igemdaymeet

The main degree provided by IISERs are BS-MS in any natural science stream. Since the institutes are new in India and so is the degree provided by them, many people in India, even the educated ones are not aware of what does this degree means and often mix it with BSc and Msc. The degree has already been offered in foreign countries like US, Germany, etc but was introduced in India after establishment of IISERs. BS-MS (Bachelor of Science – Master of Science) is a five year dual degree program. The program focuses to train students to pursue a career in academia, R&D institutes and science based industries. They are introduced with the idea of how to carry with the research and build up a career. The motivation is the reason why IISERs are equipped with world-class lab facilities and highly exceptional researches are carried out in these labs.

Besides the BS-MS in natural sciences, as the institute is growing and establishing new departments, some of the IISERs are offering only BS (4 years )as well, not only in natural science stream but in engineering sciences and economics as well. IISER Bhopal is the one offering BS in Engineering Sciences (Computer Science, Electrical Engineering, Chemical Engineerning) and BS in economics. IISERs are said to be on the same level for research as IITs are for engineering. Now, recently, IITs have also started offering BS-MS degrees. IISERs provide a great opportunity for young, innovative and bright minds to excel in science and research. IISERs have collaborated with many foreign universities, research institutes and industries and is rapidly gaining recognition due to the work done by its student members and faculty members. The institute is expected to excel exponentially and become a very great opportunity to students.

ANCIENT INDIAN HERITAGE

India has a long history behind it, though as an independent nation it is still a rich. India is rich in almost every aspect of human activity. This richness is not of the recent past but dates back to thousands of years. We, living today, are heirs to a rich, healthy heritage which is the envy and admiration of the rest of the world. Our culture is one of the best and oldest. The nations which are highly developed and which hold an important place today in the comity of nations, were little known at a time when the glory of India was widespread. Many things have contributed to the proud heritage that has been handed over to us by our forefathers.

Evidence of our heritage and culture can be got from the excavations made in Harappa and Mohenjodaro. The Indus Valley Civilisation is one of the oldest and offers proof of a great culture that existed in the distant past. The Vedas and the Upanishads, the oldest of literatures are rich in pearls of wisdom. Spiritual and moral ‘tenets’ and guidance are got in plenty from these. They transcend boundaries of nations or creeds or religions, but apply to the whole world. Among the greatest epics of the world are the Ramayana and the Mahabaratha. The Bhagavat Gita is a Universal Document of Wisdom and Truth, holding a rich store of knowledge in various aspects of life. One who is an avid reader and follower of the Gita will get its truth instilled into one’s nature and such a one will be looked upon with love, respect and admiration by others, such is the value of the classic. undefined

Kings and Emperors in ancient days were patrons of art and literature. They have had counsellors who gave them valuable guidance and advice not only religious matters but also on the economic, social and political aspects of life. There were also men of genius who entertained the kings and the people with their poetic skill and imagination. There is no subject left untouched or unadorned by our ancients. Great men like kalidasa and kautilya will live as long as human beings inhabit this world. “Shakunthalam” and “Meghadoot” of Kalidasa and “The Arthasastra” of Kautilya are immortal. The latter is a treatise on political philosophy of the highest order.

Art, architecture, painting and sculpture, weaving, music and dance…. there is no field left undistinguished by our ancients. Artists of every description were patronised by great Emperors and Kings some of whom were themselves eminent in the arts and music.Temples are repositories of architectural beauty and monumental proof of the artistic skills of people of the past. Many examples of beautiful temples can be found. The Brihadeeswara Temple at Thanjavur in Tamil Nadu is a standing testimony to the technological protection that was the hallmark of such structures. It offers proof for the technical proficiency of the builders who did not have any of the advantages that modern technology offers to builders.

Arts and architecture of the ancients were developed later by others and even foreign rulers of India admired them and made them blend with other cultures. Bharatanatyam, Kathakali, Kathak and Manipuri among dances, the Kushan, Gandhara and Guptha forms among art forms, were revelations to the innumerable foreign travelers who visited India at various times in the past. Painting was not far behind these, as is evident from the Ajantha paintings. A modern marvel of art and architecture that had its roots in the past and which is a fine legacy left to us in Mamallapuram or better known as Mahabalipuram near Chennai.

Considering all these facts, it may be said that our heritage is one of the valuable treasures handed over to us by our forefathers. Western education, adoption of Western modes of dress and ways of life, faith in rationality, disbelief in religious tenets and truths tend to undermine the value of our heritage. It is the bounden duty of everyone, every Indian worth his salt, to preserve the ancient heritage handed over to us, so that we would be in a position to pass on this wealth of wisdom to posterity. We have to see to it that divisive tendencies do not destroy the cultural heritage that has come down to us through the centuries. India and culture should ever be an inseparable combination that should act as a model and a beacon light to the rest of the world.

CARE OF THE AGED

Now we are living in a world with developed science and technology. Society has undergone a number of changes owing to the advancement of technology. A significant effect of technological developments is felt on institutions like family and religion. It is generally in the economic field that the effect is felt more.

A family is generally defined as an association of a man and woman with or without children, when their association is a legal one. Joint family system is one of the important forms of the family. When different generations of the same family live together it is known as joint family. Here all the members live together, the affairs of the family being in the hands of one member, generally the oldest. Even today there are a number of places where the joint family system exists. But with the increase in technology and science there begins a split in this system. Joint families are replaced by single unit families. The reasons for this are obvious.

A member of a joint family may have to go to a long distance to be in time for his work. To avoid the waste of time, money and energy he may prefer to live near the work spot and so may set up a separate household. This divides the family. Again, during these days women also come out to seek employment, because there is a realisation that with spiraling costs it would not be possible to run a family with only the earnings of one member. So when women also get employed and when both the husband and the wife begin to earn, there is an improvement in the family income. But the same advantage is also combined with a shortcoming. The older members of the family have to fend for themselves, since the assistance of the young members is not available, even if the parents live with the children. But if the sons or daughters live away from their parents who live alone they feel helpless in their old age.

In some families parents also live with their married sons or daughters. In such cases there may be clashes of temperaments and differences of opinion. The younger generation may feel that parents are a hindrance and obstacles in the way of their happy life. They, therefore, develop a tendency to ignore or neglect their parents. In such circumstances the old people feel the intensity of their loneliness and unhappiness. They feel that they are unwanted and suffer great humiliation thereby.

In addition to such old parents neglected by their children, there are others who, in their old age, suffer the pangs of poverty and penury because they do not have any one to look after them. They might have lost their children and may be at the mercy of other people on whom they rely for their support. The condition of these people would be miserable, without money, without people and without friends.

The life of old people is so miserable that they yearn for company and help. It is such cases they should be pitied. Today, society has come forward to assist them. The government has formulated a number of schemes to help the helpless old people. Old age pensions are given to all people who pass a certain age and who are destitute. Here also some unscrupulous people take advantage of the old people’s condition. In some families, the sons make their parents apply for these pensions and then taking away that money make the parents suffer. But such cases are not many.

Governments and some private charitable institutions also conduct homes for the old and helpless. Helpage Homes are meant to offer protection of the old and helpless. At these places, old people are not merely taken care of, but also are offered means of recreation. In some of the institutions, the inmates are induced to take up some occupation or other according to their aptitude and ability. They are encouraged to perform some work or other and in some places they are even paid small sums for the work done. This helps them spend their time happily and profitably.

The care of the aged has now become the responsibility of the Government and the Society. Yet, there are many old people who are ignorant of the existence of such places, or they do not have anyone to help them to get into such institutions. It is, therefore necessary that more people, especially wealthy people and social service Organisations should come forward to take care of the old and aged. The aged deserve such help. While young and active they would have done their best in their own way to serve the society of which they were parts. But since they are neglected in their old age, something should be acknowledged and in their helpless state they should be given the consolation and peace that would make them reasonably happy.
