Women Strike for Peace (WSP), a female activist group formed at the height of the Cold War, transformed the American women from a passive victim of patriarchal militarism and politics into an active fighter for peace. By empowering the female voice in America, WSP played a vital role in ending the dangers that American families faced due to the Arms Race, and the beginnings of more peaceful relations between rival superpowers, America and the Soviet Union. Heated Cold War tensions between…

plays an important role for setting up the cost of electricity of geothermal systems. 1.3 TYPES OF GEOTHERMAL RESOURCES Geothermal energy comes from the natural generation of heat mainly due to the decay of the naturally occurring radioactive isotopes of potassium, thorium and uranium in the earth. The estimated total thermal energy above mean surface temperature to a depth of 10 km is 1.3 x J, equivalent to burning 3.0 x barrels of oil. Since the global energy consumptions for all types of…

other words, hydrogen has one electron in its outer shell and is in Group I, carbon has four electrons in its outer shell and is in Group IV, and so on. Elements with the same number of electrons in their outer shell have similar chemical properties. Isotopes Neutral elements always have the same number of protons and electrons. However, they can have differing numbers of neutrons, so some atoms of a particular element may be heavier than other atoms of the same…

Although government research led to world changing creations and discoveries, there remained a darker side to these experiments. The use of human test subjects was a near universally accepted idea in the scientific world. Many of these subjects were of a lower class or otherwise undesirable backgrounds, putting them at a disadvantage to receiving their proper rights and choices. Regardless of the several benefits, many argue that the ends did not justify the means. Opponents of human testing…

Potassium is everywhere. It races through the bloodstream, drifts in the air, swims through the water, and rises up roots of plants. Furthermore, it is vital for life to exist on earth, from the grass lions, bears, and humans trample on every day, to the fish and plankton in the ocean. Without potassium, the ninetieth element on the periodic table with chemical symbol “K,” life would be immensely different today, notwithstanding any in the first place. Potassium functions a significant role in…

contact with the patient’s body (Cancer Council Victoria). Internal radiotherapy involves placing a source of radiation inside the body on or near the cancer (Cancer Council Victoria 2014). This includes radioisotope treatment, where a radioactive isotope is given as a capsule or, brachytherapy, in which a permanent or temporary radiation source is put near the cancer inside the body (Cancer Council Victoria…

around the age of 10 at the time of the disaster. Rates of thyroid cancer were elevated compared to what it was likely to have been, had the disaster not taken place. The thyroid gland, especially in children, traps iodine, one of the radioactive isotopes released into the environment after Chernobyl. The study found the tumors taken from these patients had fusion-oncogenes, which means DNA breaks apart and comes back together. This is a typical observance with radiation caused cancers (Grisham,…

The Language of God Francis Collins was a man that accomplished something that was not thought to happen during his lifetime. That was to sequence the entire human genome. He was the director of the Human Genome Project which has been completed. Three years after mapping the entire human genome which consisted of 3.1 billion letters, he went on to write The Language of God. He is a theist which is uncommon for a scientist. The first 6 chapters of The Language of God broke the ice. It gave the…

Differing Sources of Energy; Differing States of the World Energy is the source of nearly all our everyday tools and amenities, without it papers would not be able to be written and getting to school would be an adventure in itself. The different sources of energy provide differing amounts of energy and differing amounts of pollution, costs and environmental impacts. Nuclear energy, coal power, tidal wave power and wind energy are just a few of the different types of energy we use to supplement…

unprecented power. FDR created the Uranium Committee to further investigate into this massive project. This project was officially called the Manhattan Engineer District(MED). This project was a $2-billion dollar effort that required them to obtain the two isotopes(Uranium and Plutonium). These two were used in the of the process called gaseous diffusion. On July 16, 1945, near Alamorgordo, The “Little…
