Introduction Atomic Absorption Spectrometer (AAS) is an analytical equipment commonly used for the detection of heavy metals in particular sample. The first step to analysis in the AAS is the atomization of the desired element by converting it to a gaseous state. The atoms then absorb the energy emitted from the hollow cathode lamp corresponding to the desired element and a detector reads the signal and records the results. The results may be used quantitatively or qualitatively depending on the

Debate Intro The pictures in front of you are the gruesome results of the utter destruction after the atomic bombs were dropped on both Japanese cities. Almost half a million victims; equivalent to 13‚000 tons of TNT; a 1.6 mile radius of destruction/bomb (within that radius‚ people were disintegrated‚ leaving shadows where they stood). Housewives and children were incinerated instantly‚ their internal organs boiled and their bones charred into brittle charcoal. 65% of the casualties were nine

On August 9th‚ 1945‚ the second Atomic Bomb was dropped on Nagasaki‚ and only three days earlier the first was seen in Hiroshima. These were two of the numerous events that propelled the most powerful combatants in history‚ the United States and Soviet Union‚ into the dangerous arms race we know as the Cold War. Many ask‚ “Was it necessary?” This is a controversial topic‚ asking whether or not the massacre of hundreds of thousands of Japanese civilians was worth saving a much smaller number of military

In 1945‚ when the atomic bomb was dropped in Japan I felt that it was not justified. Even though it saved thousands of American lives it was at the cost of others lives. The United States could have gave the Japanese a warning before dropping not one‚ but two bombs on them. However‚ the Japanese did not surrender until after the second bomb I think a warning would have made the bombing “justified.” To begin with‚ even though the United States and Japan were at war and were protected their own citizens

On July 29th 1957‚ the United Nations established an autonomous international organization called the International Atomic Energy Agency that would to promote the use of nuclear energy for peaceful reasons‚ insure nuclear safety‚ and retrain the usage of nuclear power for military and strategic purposes such as nuclear weapons. The IAEA is an independent intergovernmental‚ science and technology based organization that is a part of the United Nations and serves as the global focal point for nuclear

On May 7‚ 1945 Germany surrenders‚ and as Germany falls Hitler committed suicide thus ending the war in Europe. Several months later and after many American deaths President Truman decides to drop atomic bombs on Japan. According to Joel Wooton the first bomb known as “little boy” was dropped August 6‚ 1945 on Hiroshima‚ Japan. “Hiroshima‚ Japan was chosen to be bombed because it was the only city out of the 7 they had saved to bomb that one wasn’t under a lot of cloud cover.” (Wooton) They dropped

C. S. Lewis comes across to many Christians and non-Christians readers as a writer whose purpose is to make others contemplate what is beyond nature. In this particular case of “On Living in an Atomic Age‚” Lewis writes to numerous audiences to proves that nature is not “the only thing in existence” (Lewis 75). He believes that there is ‘another world’ beyond nature. Before Lewis gets to this part of the essay he goes on to explain what nature is in its truest form. Lewis makes it clear that nature

One interesting event from 1960 was the testing of the first atomic bomb by France. Between 1960 and 1966‚ seventeen bombs were tested by France. These bombs leaked radioactive materials that are still affecting citizens near the bomb sites in the Sahara Desert. It is estimated that hundreds of soldiers and nearly thirty million civilians were knowingly exposed to the radioactive areas. The bomb testings and radioactive exposure were reportedly meant to “study physiological and psychological effects
