Isotope

Project there were multiple teams that did different parts of research without knowing anything, they just thought they were being sent to do research for a project. One branch produced Uranium-235 by using a Graphite Reactor, a machine that produced isotopes. Another produced Plutonium-239 from the Graphite Reactor as well. All the products produced by the branches were sent to the main base to assemble bombs. But how did The Manhattan Project change…

1. Pressures on early hominins to adapt to meat-eating • Emergence of early hominins from wetland forests to bipedal open grassland inhabitants led to food sources not previously available, namely the availability of large grazing animals. (Mann, 2007) • A higher quality diet shortened the duration of suckling and lactation during early hominin development, allowing an increase in reproduction rates and a decrease in the time needed between births. (Psouni, Janke & Garwicz, 2012) 2. Anatomical…

evidence about how people lived in society from then on. Thus, scholars often study groups of people more recent times whose technology and way of life offer parallels with those people distant past. Another, type of test was used was radioactive isotope of carbon (C-14). This test breaks down of how long certain objects were used during the Paleolithic era, and determined how old is it.…

Is Thorium a good alternative? Thorium is a slightly radioactive metal that is made in rocks and soils, it is a significant replacement for uranium in the nuclear energy sector. As we continue to remain uncertain of our future supply of uranium, thorium is being seriously considered as an alternative to uranium to provide us with nuclear power at not only a reasonable cost but is also abundantly safe. For example, India has been looking at thorium for years, according to the US Geological…

their amounts of neutrons, protons, and electrons to one another and drawing out structural and molecular formulas, to make it look like their electrons would increase alternating between the drawings. However, their atomic number, atomic mass, and isotopes reminded them no matter how much they tried to compare, they would end up bonding both ionic and covalently, whichever…

Well, President Roosevelt put together a team of scientist led by Robert Oppenheimer to build this Weapon of Mass Destruction. The bomb was made out of a Radioactive isotope of Uranium, Uranium 235. This Bomb was 2 billion dollars’ worth of research. The Bomb was ten feet in length. On August 6,1945 a B-29 plane named the Enola Gay set out for Hiroshima . Strapped to the bottom was the “Little Boy”, or the Atomic Bomb…

Hyperthyroidism The thyroid stimulating hormone is secreted by the pituitary gland. Hyperthyroidism is a condition in which the thyroid gland is over producing and makes an excessive amount of thyroid hormone. The thyroid gland is and organ that is located in the front of the neck and releases hormones that control your metabolism. Symptoms: When the thyroid gland is over active (hyperthyroidism) the body process will speed up and you may experience nervousness, anxiety, and rapid heartbeat,…

Prior to the Great Oxygenation Event (GOE) there was little oxygen in the atmosphere. Oxygenation of the atmosphere occurred in two steps, at the beginning and end of the Proterozoic eon (Frei, et al., 2013). In the GOE the surface oceans began to become oxygenated (Holland, 2006). The Second stage of oxygenation is known as the Neoproterozoic Oxygenation Event (NOE) and occurred after the 650-635Ma in the Marinoan glaciation (Sahoo, et al., 2012) (Feulner & Kienert, 2014). The NOE is thought to…

It takes place at such high temperatures that the gas produced turns into plasma. Usually, fusion is not feasible because of the electrostatic repulsion between 2 nuclei but if circumstances can be achieved where the 2 hydrogen isotopes, deuterium and tritium are heated to such an extent that they can overcome electrostatic repulsion, the 2 nuclei can fuse to release a tremendous amount of energy. This is currently being achieved by the Tokamak reactors. Nuclear fusion doesn’t risk…

One of the largest environmental disasters in world history happened on March 11, 2011. The site was the Fukushima nuclear power plant in Japan. A 9.0 magnitude earthquake was experienced off the northeastern coast of Japan, and this triggered tsunamis that affected shorelines within minutes. Dozens of villages alongside 200 miles of coastline were substantially destroyed. Waves measuring more than 40 feet struck the Fukushima nuclear power plant, located only 150 miles from Tokyo. The…
