  • Perspective – Pondering Over Poverty-SDG one

    Of all Sustainable Development Goals (SDGs) universally acknowledged and designed to deliver human security, the prime mover is SDG-1, No Poverty. Poverty has been the curse of humans  and humanity has now geared  to banish  extreme poverty in another 8 years with bell book and candle. No, Big No to Poverty.

    Poverty

    What is poverty? Those who have experienced it, know it far above poignant words.. Poverty is about just having enough money to meet basic needs including food, clothing and shelter. The World Bank Organization describes poverty in this way: “Poverty is hunger. Poverty is lack of shelter. It is the ultimate degradation of human condition. Humans, one hundred watt thermal machines, are unable to feed energy for their very survival. This existential condition is poverty. It signifies Maslow’s package of physiological needs,  Roti, Kapda and Makkan.

    Poverty strikes society brutally. Jawaharlal Nehru referred to poverty in the Discovery of India thus: “There was lack of food, of clothing, of housing and of every other essential requirement of human existence… the development policy objective should be to get rid of the appalling poverty of the people. Poverty stunts society at all levels. Studies show that children from poor families have smaller brains and lower cognitive abilities.

    Poverty Line

    Economics, a ‘dismal science’ deals with wealth and lack of it in equal measure. There are haves and have nots. Yet a simple redistribution is no panacea for sustained economic growth. Bernard Shaw humorously referred to his luxuriant beard and bald head probably signifying that averaging would not work out.

    Figuratively we have a line, connection between two points. It is known as the poverty line. The international poverty line, which is currently $1.90 a day, is the threshold that determines whether someone is living in poverty. The line is based on the value of goods needed to sustain one adult. This does not take into account access to sanitation, water, and electricity and what effect that has on their quality of life. Yet it is a reasonably good measure of the pathos of poverty.

    In our country, poverty has two gruesome faces, one in our villages and the other in our towns and cities. In urban areas, it is 1,286 Rupees, and in rural areas, it is 1059 Rupees per month. It is painful to note that the number of the poor in our country has more than doubled from 60 million to 134 million in just a year because of the pandemic-induced recession. This means we have  returned to a sad situation where ours is called a “country of mass poverty” after 45 years. This is in striking contrast to our spectacular success stories of Green and White Revolutions. We now need a revolution within revolution to liquidate poverty in all its ugly forms.

    Poverty: Effects

    Poverty is linked with negative conditions such as substandard housing, utter homelessness, inadequate nutrition and food insecurity, inadequate child care, lack of access to health care, unsafe neighbourhoods, and under-resourced schools which adversely impact our children. It is a baggage of ugly and dirty facts staring at us straight in our face. The tentacles of poverty suck verdour out of our body social and leave it emasculated

    Poverty: Causes

    We are victims of the population explosion and have multiplied maddeningly. We have the staggering number of 1.3 billions and are still breeding. During the past 45 years, our population  has shot up at a rate of 2.2% per year, which means, on average, about 17 million people are added each year, so many mouths to feed. This increases the demand for consumption of goods tremendously.

    Our agricultural productivity is abysmally low owing to multiple factors. Fragmented and subdivided landholdings, lack of capital, illiteracy about new farming technologies, traditional methods of cultivation and  wastage during storage are prominent among them. Unemployment and underemployment are tragically  ingrained in the farm sector as also in other sectors. The shortage of capital and entrepreneurship is making it harder to increase production. There are also political and social factors relentlessly operating adding to our vulnerability.

    Nuclear Option

    Solutions to the problem of poverty  have to be sought in several domains concurrently and coherently. Technology is patently a single critical variable. Nuclear science and engineering have a lot to offer to alleviate poverty. Electricity generation helps reduce poverty and stimulates economic growth. Nuclear generation provides affordable and reliable electricity supplies without greenhouse gas emissions or air pollution. Investment in nuclear energy boosts economies and provides employment. A brave new world with SDG-1 fully realized is within our reach if we have a clear nuclear vision.

    Globally, over 700 million people do not have access to electricity. Billions more have unreliable supplies. A reliable, clean and affordable electricity supply is essential to enable people to rise out of poverty and improve their quality of life. Nuclear generation costs are much less susceptible to fuel price volatility than fossil fuel generation costs. This can help mitigate the impacts of fossil fuel price spikes on energy prices, which disproportionately affect poorer households. Strategies to decarbonize electricity supplies should also take account of the potential impacts of higher generation costs on those least able to pay. Extending the operation of existing nuclear reactors is one of the lowest-cost ways of producing low-carbon electricity as we have done at our Tarapur Power Station.

    Realizing the critical role of electricity in developmental economics, Dr. Homi Jahangir Bhabha famously said, “ No power is costlier than no power”

    Nuclear Agriculture

    Nuclear applications in agriculture rely on the use of isotopes and radiation techniques to combat pests and diseases, increase crop production, protect land and water resources, ensure food safety and authenticity, and increase livestock production.

    Bhabha Atomic Research Centre has  developed high yielding seed varieties by inducing mutations using Gamma radiation. Gamma radiation only accelerates the mutations which otherwise occurs naturally over a much longer periods of time. About 50 seed varieties are in the field as part of commercial exploitation. Mutations can be in such a way that the crops mature early, to withstand biotic and abiotic stresses and to obtain better nutritional quality. Biotechnology offers infinite solution potential.

    Food Security

    Food security, a sure antidote for poverty, for the expanding population  can be had by the application of nuclear techniques which help maintain healthy soil and water.

    Another interesting story is that of the nuclear-derived sterile insect technique which involves mass-rearing and sterilizing male insects before releasing them over pest-infested areas. The technique suppresses and gradually eliminates already established pests or prevents the introduction of invasive species – and is safer for the environment and human health than conventional toxic pesticides.

    Food safety and quality control systems need to be robust at national level to facilitate the trade of safe food and to combat food fraud, which costs the food industry up to USD 15 billion annually. Nuclear techniques help improve food safety by addressing the problem of harmful residues and contaminants in food products and to improve their traceability systems. The agricultural sector uses nuclear technologies to adapt to climate change by increasing resource-use efficiency and productivity in a sustainable way. Sustainability science is built into nuclear applications.

And to manufacture all these and implement them you require highly trained engineers, scientists and technicians specializing in areas such as aerospace, aeronautics, electronics, computer science, robotics, chemistry, physics and meteorology. In short, Aerospace Engineers are engaged in high tech fields such as manufacturing of aircrafts for commercial or military use, space research and spacecraft production.

    Job Profile

    The primary job of an Aerospace Engineer is to design, create prototypes of these designs, and finally test them. The work may also involve evaluating designs of other engineers to make sure that the idea meets certain ethical, safety, and environmental standards. Overlooking building process as well, ensuring that proper deadlines are met is also part of work of an Aerospace Engineer. Typically, an Aerospace Engineers specializes in either aeronautical or astronautical design, which will determine whether they work with aircraft or spacecraft.

    Work Demands

    Using high-end computers and sophisticated programs, an Aerospace Engineer spends much time in an office setting. At times, you might find an Aerospace Engineer working in a manufacturing environment to oversee the construction and implementation of a design. Aerospace Engineers work fulltime on regular basis. However, managing larger projects can require overtime hours, particularly when deadlines are approaching. Also working at the forefront of technology makes long career breaks difficult, as they need to keep up-todate with industry developments.

    Skills Required

    Above average intelligence Excellent academic background Responsible attitude Ability to put in long work hours and days at crucial assignments Good analytical ability Scientific acumen Ability to undertake challenging assignments

    Institutions

    Indian Institute of Aeronautical Engineering, Dehradun

    Rajasthan Institute of Technology and Engineering Science, Kota

    The Indian Institute of Science, Bangalore

     

    Qualification Required

    Students who want to build their career as Aeronautic Engineers are advised to prepare for the career path well in advance by focusing on science and mathematics in high school. Students who have successfully completed 12th or equivalent with PCM/ PCB are eligible to apply for the entrance exam for Aeronautical Engineering for B. Tech. course. The minimum percentage required for it is 60% for most of the entrance examinations. They could also go in for post graduate and doctoral studies in the particular field of interest.

    Future Prospects

    Mostly Aeronautical Engineers get jobs at automobile or power companies, where the principles of turbines or engines come into play. Companies like BHEL, L&T, Tata Power etc. can hire aeronautical engineers. But yes, if you’re seeking purely aerospace jobs, then try to apply at ISRO, which is one of the world’s top space agencies. You can also seek jobs at DRDO (makes missiles and fighter jets), Hindustan Aeronautics Limited (HAL) or National Aeronautics Limited (NAL). However, bagging a job at either ISRO or DRDO is extremely competitive because the positions are few and there would be many applicants

  • Perspective – Avenues for Research

    21st Century is the knowledge driven society. The Scientific Knowledge has many avenues for conducting and implementing Research. This article explores the different avenues for Research…

    Knowledge is the product of processed information analysed, digested and enriched with experiences. Mere knowledge is of no value as it needs to be utilized for a useful purpose for the benefit of the society at large

    Integration

    As Physics teaches universal principles. Engineering methods are used to convert these principles into technology resulting into products which are created and utilised by the society.
    Similarly, you know elements and their properties by learning Chemistry. The conversion of this knowledge into chemical products gives us  almost everything what you see around us which are very much needed for our daily routine.
    By learning Botany we know about the plants, know the classification, identification and properties applying this knowledge, using agriculture techniques, we know how to plant them, utilize as a crop and convert them into food for all . Same thing applies in Zoology or Microbiology as well in every other basic science subjects.

    Comprehensive Approach

    When a scientist or researcher starts his work he doesn’t segregate the above subjects as separate entities. He utilises integration of the Knowledge from various branches which leads to developing technologies for the benefit of Society

    Let us take an example of solar energy.
    Solar panels are needed to absorb sunlight. Here all types of expertise is needed. Physics, Chemistry with the help of Mechanical, Metallurgical, Electrical as well as Electronics principles are integrated. For the installation of these heavy panels at a place where maximum sunlight will be available is to be selected and erected by a Civil engineer but design is provided by an architect.

    Integration

    Scientists integrates all these ideas on paper keeping in mind their merits and demerits. When such a model is conceptualised on paper and tested, or replicated the cost effectivity is also calculated to make the technology viable.

    When you are dealing with environmental or ecological science, interdisciplinary information and its analysis is a must. More in-depth analysis is needed in astronomy, astrophysics, oceanography and meteorological science. Fields like atomic energy, rocket science and advance computer technology need very complicated research. Here teamwork, collaboration is needed to establish or to achieve any reasonable success .

    Agricultural needs

    In past many need based agricultural products have been developed by the farming community. The major resources needed for agriculture, along with soil is the manpower.. the availability of the agricultural labour is in shortage in the country. To overcome this, The mechanization is the answer… The development of the advanced technologies used in agriculture such as tractors, tillers need the integration of various technologies other than pure agriculture.
    In the agricultural sector various small instruments are operated using electricity or diesel. Availability of power is becoming crucial; however, the Problem arises from load shedding or non availability of the diesel. The solution to overcome the problem could be to make the power available or by creating small novel devices to help farmers .

    Waste Disposal

    All over the world the major problem is disposal of various type of waste products. Composting or utilising that waste for power generation is practiced. Though in small scale in different areas of the city it is now a model used in various countries. Discarded electronic material waste is incising beyond proportion. Recycling them and procuring the rare metals poses a challenge …

    Recycling the polluted water in the rivers is a very big issue in India. At the same time how to stop evaporation of water from the dams is also an age old issue.

    Thus to discover the various research avenues in modern times the integration of the different subjects is needed…The approach should be interdisciplinary… While solving the different problems and to help the society, you must focus on any such area of your interest with interdisciplinary approach then you can discover or even invent something.

  • Do you Know??

    Know the fascinating Facts….

    Why is DIAMOND the hardest substance on Earth

    Diamonds are incredibly hard because they have crystallized in a particular atomic shape after being subject to the effect of heat and pressure on Earth at a depth of 140 to 150 kilometres. This makes diamond the hardest mineral on earth and cannot be broken or cut easily. It is only possible by using another diamond.

    Why do FORMULA 1 driver lose weight

    The F1 drivers can lose up to three kgs weight after a race due to extreme heat in the cockpit of the vehicle. Hence, the drivers take in large amounts of water before the race, even if they do not feel thirsty, to avoid dehydration through sweating

    Why do we get HEATSTROKE

    Heatstroke is a condition caused by your body overheating, usually as a result of prolonged exposure to or physical exertion in high temperatures. This most serious form of heat injury – heatstroke, can occur if your body temperature rises to 104 F (40 C) or higher.

    Why do NEWSPAPERS turn yellow over time

    Paper is made from wood, which is made up mainly of white cellulose. Wood also has a lot of a dark substance in it called lignin, which ends up in the paper, too, along with the cellulose. The exposure of lignin to air and sunlight is what turns paper yellow.

    Why is SUN harsh in summer

    In the early morning and late evening, UV (ultraviolet) radiation is less strong because the rays have farther to travel to get to the Earth. But throughout the year, the sun’s angle varies with the seasons, so the strength of UV rays change, too. UV rays are strongest in the summer months.

  • Ocean Currents Stops

    Ocean currents play a significant role in controlling climate around the globe. These currents act like a giant conveyor belt, warming and cooling parts of the Earth as water circulates. Melting ice caps, which can happen due to global warming, can cause ocean waters to circulate and have a drastic effect on climate…

    What are Ocean Currents ?

    Around the world, there are a number of ocean currents which have a serious impact on climate. For instance: The Gulf Stream in the Atlantic transports warm water with a high level of salinity and low density from equatorial regions further north on the ocean’s surface, warming countries such as the United Kingdom.

    The further north the water travels, the cooler it gets. Cold water becomes denser, falls further towards the bottom of the ocean and is carried back further south. This causes a continual ocean current in the North Atlantic.

    Global Warming

    Polar ice caps are beginning to melt due to global warming. Since ice caps are composed of freshwater, and if they continue to melt, it would bring down the level of salinity in the surrounding ocean waters. Changes in salinity levels could affect thermohaline currents by preventing water from achieving enough density to sink to the bottom of the ocean. More seriously, ocean currents could stop completely.

    Effects of Ocean Currents

    If ocean currents were to stop, climate could change drastically, especially in Europe and countries in the North Atlantic. In these countries, temperatures would drop, affecting humans as well as plants and animals. In turn, economies could also be affected, particularly those that involve agriculture. If these effects were to continue, Europe, North Atlantic countries and parts of North America could experience long periods of freezing conditions. Also, if ocean currents stopped because of climate change it will have many other affects associated with the globalwarming phenomenon.

    Earlier Phenomena

    Earlier evidence of rocks and ice have shown that ocean currents have indeed stopped for periods of time in history. One example can be found around 13,000 years ago when the warmth experienced at end of an ice age caused large masses of ice to melt into the sea.

    The resulting changes in water density stopped ocean currents from flowing and caused freezing conditions in some parts of the world for over 1,000 years.
