Effect Of Nuclear Energy On Environment Part -II

By
In continuation of my earlier note on the subject, I am to add the following -
There are other energy sources that are highly effective without the huge risks of Nuclear pollution or irradiation - Geothermal sources, Ocean currents, Tidal waves, wind and waterfalls all make alternative power solutions that should not be neglected. Environment -friendly electricity is one of the chances this Planet has to survive.

Attempts have been made by an American company to build a Radioactive Storage Facility on Marshall Islands ignoring the even higher potential threats for nuclear pollution under the circumstances of a growing sea level. Such solution may appear convenient from a certain point but from a wider point of view, irresponsibility is obvious.

Nuclear power is a power, generally electrical produced from controlled, that is non - explosive nuclear reactions. 15% of world's electricity in 2009 came from nuclear power,despite concerns
about safety and radioactive waste management. More than 150 Naval vessels using nuclear power
have been built.

Nuclear radiation is nothing more than emission of energy waves through space, as well as through physical objects. The actual radioactivity is a result of radioactive decay.
The three types of radiation with varying abilities to penetrate objects and bodies are - Alpha, Beta and Gamma radiation. One can shield from Alpha radiation by something as flimsy as a sheet of paper. Beta rays needs six millimeters of aluminum and Gamma rays are stopped by dense material only like Lead. They travel easily through an inch of lead. Higher you are in the earth's atmosphere, more you are exposed to these rays because the further they travel in to our atmosphere, more they are slowed down. Astronauts are exposed to high levels of cosmic radiation.
Nuclear power has developed into a mature and commercial reality with its part of success and threats. Although Nuclear power can be used to generate electricity in an environment friendly manner, it is a subject of controversies owing to the threats related to it.

Qualities Of A Good Prime Minister

By
Following are ten qualities (not in order of importance), which I believe are the most important for a Prime Minister and why ? - 1) Ability to connect with constituents - All great leaders in history had a penchant for being able to connect with their citizens i.e. a strong or habitual liking for something or tendency to do something. Leaders who have failed have probably failed in this domain. 2) Clarity of vision - The Prime Minister who knows their vision and can successfully articulate it to the voting public is one who will be held in high regard. 3) Coherent grasp of domestic issues - There has to be a keen desire and understanding of domestic concerns that directly impact the citizens. Failure to understand and address these issues will create a gap between what the Leader does and how it impacts their citizens. 4) Clear understanding of different cultures in their Governance - All good leaders will be able to understand the Political culture, Ethical/ Racial cultures, Cl

Working Of Nuclear Plant and Generation Of Energy

By
Nuclear energy originates from splitting of Uranium atoms- a process called fission. This generates heat to produce steam, which is used by Turbine generator to generate electricity, because Nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions. It is the safe, clean, cost effective alternative contrary to claims by opponents of nuclear energy. Nuclear power reactors use controlled nuclear fission in a chain reaction. With the use of neutron absorbers, the rate of reaction controlled, so the power depends on demand. By reliably providing power 24 hours a day, Nuclear energy is an important part of the energy mix necessary to meet electricity demand. And, with no carbon emissions, it will remain an important clean energy resource for the future. For more than forty years, Duke Energy, USA has operated nuclear plants- setting industry benchmarks for safety and efficiency in the process. Working of a Nuclear Plant - A Nuclear power plant works much like a

Artificial Intelligence on Business Forecasting

By
The business world today is driven by customer demand. Unfortunately, the demand patterns vary considerably from time to time. That is why it can be so challenging to develop accurate forecasts. The goals of forecasting are to reduce uncertainty & provide benchmarks for monitoring actual performance. A new generation of Artificial Intelligence technologies have emerged that hold significant commitment on improving forecasting process including applications as product demand, employee turnover, cash flow, distribution requirements, manpower forecasting & inventory. Artificial Intelligence systems are designed to bridge the gap between the two traditional forecasting approaches - Managerial and Quantitative. Artificial Intelligence is defined as a Computer Based analytical process exhibiting actions and behavior considered ' Intelligent' by human observers. A.I. attempts to mimic human thought process including reasoning and optimization. One purpose of A.I. is

FDI - Foreign Direct Investment- Types And Essentials

By
FDI started in India in 1991 in wake of economic crisis and since then it has steadily increased. It is an investment made by an individual or firm in one country into business interest located in another country. Besides being a critical driver of economic growth, FDI is a major source of Non-Debt financial resource for the Economic Development of India. Foreign companies invest in India to take advantage of relatively lower wages, special investment privileges (Tax exemptions) etc for a country where foreign investments are being made. It also means achieving technical know-how and generating employment. The India Govt's favorable policy regime and robust business environment have ensured that foreign capital keeps flowing into the country to improve in view of ease of doing business and relaxation in FDI norms is yielding results. FDI equity inflows in India was US $44.37 billion in 2018-19 mainly on account of Service Sector, Computer hardware and software, Trading, Telecomm

Satellite Prediction Of Floods In India

By
Floods are one of the most devastating and costly national disasters each year affecting on an average 96.9 million people worldwide and causing $13.7 Billion in damages according to U.N. Office for Disaster Risk Reduction. They wash away or destroy Homes, Pollute Drinking Water and a source to giving birth to water borne diseases. The Indian sub-continent is one of the most affected due to chronic flood events mostly induced by periodic monsoon rainfall. The North - Eastern state of Assam has a complex fluvial systems of rivers, mainly with two inter connected rivers of Brahmaputra and Barak which together enter Bay of Bengal. Due to enormous sediment transport from the upper catchment areas and subsequent lack of carrying capacity of the channels in these two river valleys, flooding is a periodic phenomenon every year during the peak monsoon months from June to Sept. causing extensive damages to life and property. Satellite plays important role in detection and monitoring of flo

US Dollar - Effects in the modern economy

By
U.S. dollar is strongest currency which supports U.S. economy. The reason is that more than one -third countries of the world's gross domestic product comes from countries that peg their currencies to dollars. A strong economy will attract investment from all over the world due to perceived safety and ability to achieve return on investment. Since investors seek higher yield on investment particularly from abroad, creates a strong capital account and high demand for dollars. Economic losses of World War have resulted into destruction of capital, trade, human suffering, spread of diseases, displacement of people and destruction of environment among others. Bretton Woods system In the post war scenario, need was felt to have a system to control value of money between different countries. It means that each country had to have a monetary policy that kept exchange rate of its currency within a fixed value - plus or minus one percent - in terms of Gold.This system was agreed upon

Devaluation and causes for Foreign Exchange rates variation

By
  Indian Rupee and Devaluation  Indian Rupee was settled at Rs.13/- per pound and dollar @ Re.1/-  in 1947 after partition. It continued up to 1966 when first devaluation took place. This was carried out since Govt, was consistently facing balance of payment deficit since 1950 and failure of Govt. efforts to revive and have positive trade balance Moreover, war with Pak in 1965 and cutting off of foreign aid by USA and other countries fueled the crisis.Rise in fuel prices all around did put pressure on inflation as well.  In 1991, second devaluation took place due to downward pressure on Indian Rupee from international markets. It was a part of Economic reforms.The restrictions were relaxed on imported capital goods. Import Export policy replaced import quotas with tariffs causing major overhaul of trade policy Devaluation is undertaken as a means of correcting deficit in balance of payments.        Foreign Exchange variations and causes Foreign Exchange is one of the most impo
