Power Plants
Power Plants An electrical power plant has a nuclear reactor to produce electricity. A nuclear reactor produces heat through nuclear fission in which atomic muclei break apart releasing large amounts of energy. In the core of the reactor, a self-sustaining nuclear reaction takes place. The power level of an operating reactor is monitored by a variety of thermal, flow, and nuclear instruments. Power output is controlled by inserting or removing from the core a group of netron-absorbing control ro

Medical Testing on Animals
Medical Testing on Animals Every year, nearly 100 million animals die in research laboratories at the hands of curious scientists who perform outdated and inaccurate tests that prove no benefit to humans or animals. Before these animals die, they are routinely burned, scalded, poisoned, starved, given electric shocks, addicted to drugs, subjected to near freezing temperatures, dosed with radioactive elements, driven insane, deliberately inflicted with diseases such as cancer, diabetes, oral infe

Fusion: Our Future's Energy?
Fusion: Our Future's Energy?
Fusion: Our Future\'s Energy? Fusion energy seems to be the most promising energy source of the not-too-distant future. It is safe, it uses an energy supply that is so abundant that it will never run out, it gives off harmless waste, and it produces energy comparable to the Earth\'s sun! But are there any problems with this hopeful energy source? What is Nuclear Fusion? To understand fusion, it is a good idea to know about fission. This is the splitting of the nuclei of atoms into two or more s
Nitrogen
Nitrogen
Nitrogen Nitrogen, symbol N, gaseous element that makes up the largest portion of the earth\'s atmosphere. The atomic number of nitrogen is 7. Nitrogen is in group 15 (or Va) of the periodic table. Nitrogen was discovered by the British physician Daniel Rutherford in 1772 and recognized as an elemental gas by the French chemist, Antoine Laurent Lavoiser about 1776. Nitrogen is a colorless, odorless tasteless, nontoxic gas. It can be condensed into a colorless liquid, which can be compressed into
Lithosphere
Lithosphere
Lithosphere Notes on the lithosphere- (rock sphere) Upper most part is crust of earth. Compiled of rocks of outer crust. Outermost shell. Upper part- rocks we see at and near the earths surface. Crust is 5 to 10 km thick under most oceans and 24 to 60 km thick under the continents. The lithosphere under the crust is solid, dense material. (more dense than surface materials). Lithosphere 100-200 km. Notes on the aesthenosphere- zone beneath the lithosphere. Thick like tar. Weak because of high te
