claim that nuclear weapons are vital shields for the planet. They claim that nuclear weapons are deterrents that prevent the world from breaking out in total war. Researchers are supporting this argument by declaring how nuclear weapons have been keeping peace. However‚ other researchers and scientists deny the effectiveness of nuclear weapons as deterrents and declare that nuclear weapons will lead the world into total devastation. Many people throughout the world state that nuclear weapons have

Nuclear World If a nuclear bomb was dropped on your city‚ how would you survive? The blast from the fission bomb on Hiroshima‚ which weighed 30 kilotons‚ was equivalent to 12‚500 tons of TNT. Now‚ if this was dropped right outside your house‚ there would be no way of survival. But‚ one megaton hydrogen bomb is said to have 80 times the explosive intensity of the fission bomb detonated in 1945. The destructive force of the hydrogen bomb is near unimaginable. But first‚ let’s take a

Nuclear Radiation There are many ways that the movie The Day the Earth Stood Still and the short story "There Will Come Soft Rains" are similar. "There Will Come Soft Rains" by Ray Bradbury is a science fiction story that deals with nuclear radiation and what the future world would be like if there was an atomic bomb. This short story is a good example of what could happen in the future. The Day the Earth Stood Still is a movie that also has the same genre‚ that it is science fiction. It helps

ENERGY MANAGEMENT PRINCIPLES INTRODUCTION In the modern days energy has the significant role in our life. With development where we got comfortable life and much modern facilities where we got some problem with excessive use of energy resources as declining of energy sources‚ climate change. So it is an big challenge for present and future generations as the cost of energy increase and its supply decrease‚ older buildings needs to modified and new buildings designed to use less energy. The optimization

NUCLEAR POWER I’m against nuclear power because in my opinion it is very dangerous mostly for the population that live in the area of a nuclear power plant‚ but also for the environment and in generally for the health of all the Earth. I’m against the use of nuclear power for obvious reasons such as accidents in the nuclear power plant then in the history had made destruction and death‚ to give the two most famous examples Chernobyl(1986) and Fukushima(2011).

Nuclear Medicine Nuclear medicine has been around for more than 50 years now and stems from the discovery of x-rays and artificial radioactivity. In 1946‚ nuclear medicine made a monumental breakthrough when radioactive iodine led to the complete disappearance of cancer in a patient’s thyroid. Nuclear medicine became widely used in the 1950’s to measure the function of the thyroid‚ to diagnose thyroid disease‚ and for the treatment of patients with hyperthyroidism. By the 1970’s nuclear medicine

The Modern Nuclear Family THE MODERN NUCLEAR FAMILY The "nuclear"‚ "isolated"‚ or "restricted" family is not a recent phenomenon‚ but has existed in many cultures throughout human history. Indeed‚ the extended family of several generations is found mostly in relatively advanced‚ stable‚ and affluent‚ but not yet industrialized societies. Very primitive and very sophisticated societies seem to prefer the nuclear family model. However‚ nuclear families can vary in the
