Human Evolution In Africa
... to isotope dating, the world was averaging 4 times warmer than it now is. As time went on, the small mammal had spread throughout Eurasia. All of Eurasia then was covered in tropical forests. Primates evolved in what is now the Indian Subcontinent.
From their placement in India, then still lowland, primates spread throughout the world once more. Some returned to North America, only to be wiped out by rodents already living there. Others spread to Europe and the Middle East.
By this time, Africa had just split from marsupial overrun Gondwanaland. About a million years later it reached the Middle East, and pri ...

American Pit Bull Terrier
... did some research on the Internet trying to learn as much as I could about this misunderstood breed. I did this also to educate my parents and to tell them some facts and myths of the APBT. After some extensive plead bargaining with them and some facts and pictures, they finally gave in and let me keep her. Well, not really though. I say that because my father of all people fell in love with "Molly" as she is now known. He has said on many occasions that Molly is the best dog he has ever had, and believe me, he has had many. The point is, APBT get a bad name because of the people who own them. In doing resea ...

Hypnosis 2
... the mind is subconsciously active but the conscious mind and the body are in a sleep like state (although many consider it sleep, it actually isn’t) (Hunter). The change in these states is from “Beta” into “Alpha”. Beta and Alpha are different terms used to describe the brain waves given off during these states. When the subconscious (subcon) or “Alpha” mind is responding, different commands, or suggestions, can be implemented into the mind. The subcon mind can then execute these imbedded commands without any intervening of the conscious mind and body (Hunter).

Nuclear Power
... Barium and Krypton; however, it can split into any two atoms as long
as the number of protons equals the original amount of the protons found in the
Uranium. In addition, a mass amount of energy is released along with two or
three neutrons. It is these neutrons that can begin a chain reaction, each
neutron that is given off could collide with another Uranium atom splitting it
apart. Each of these fissioning atoms releases a very large amount of energy,
and some more neutrons.
This process continues causing a chain reaction withut any outside assistance,
and the Uranium has "gone critical"(Martindale, 794-195). T ...

Gallium
... blende. Soon after he isolated the metal studied its properties, which
coincided those that Dmitrii Ivanovich Mendelev had predicted a few years
earlier for eka-aluminium, the then undiscovered element lying between aluminum
and indium in his periodic table.
Though widely distributed at the Earth's surface, gallium does not occor
free or concentrated in independant minerals, except for gallite. It is
extracted as a by-product from zinc blende, iron pyrites, bauxite, and
germanite.
Silvery white and soft enough to be cut with a knife, gallium takes on a
bluish tinge because of superficial oxidation. Unu ...

Nuclear Energy
... to burning vast amounts of fossil fuels—making electricity production much easier on the environment.
They produce much of the electricity that fuels our economic growth. They power new industrial technologies that keep our economy growing and improve our global competitiveness.
They cut America's demand for imported oil by nearly 100 million barrels a year—reducing our dependence on foreign oil suppliers and cutting our trade deficit.
The future looks even better. Advanced-design nuclear power plants are now being developed—quicker and less costly to build, better performing, and ev ...

Nuclear Fusion
... example 10 grams of Deuterium (which can be extracted from 500 liters of water) and 15g of Tritium (produced from 30g of Lithium) would produce enough fuel for the lifetime electricity needs of an average person in an industrialized country. (Environmental Organizations, Source 4)
The problems with fusion have been numerous. One of the problems is attaining the correct temperature for fusion to take place without using more energy then you produce. Fusion reactions occur at a sufficient rate only at very high temperatures. Over 100 million degrees Celsius is needed for the Deuterium-Tritium reaction, while other r ...

... central nervous system. Like amphetamines, they causes increased activity, decreased appetite, and a general sense of well being, which can last 6 to 8 hours. After the initial rush, there is typically a state of high agitation that in some individuals can lead to violent behavior.
Contrary to the stereotype of rural areas as idyllic, protected environments in which to raise families, substance abuse is as great a problem as it is in the cities. One must realize that rural communities vary in characteristics considerably, which complicates our understanding of rural substance use problems and increases the need ...

Carbon
... gas. Sugar, starch,
and paper are compounds of carbon with hydrogen and oxygen. Proteins such as
hair, meat, and silk contain these and other elements such as nitrogen,
phosphorus, and sulfur.
More than six and a half million compounds of the element carbon, many
times more then those of any other element, are known, and more are discovered
and synthesized each week. Hundreds of carbon compounds are commercially
important but the element itself in the forms of diamond, graphite, charcoal,
and carbon black is also used in a variety of manufactured products.
Besides the wide occurrence of carbon in compound ...

Elephantiasis
... with the flow of lymphatic fluid away from these
tissues. The most frequently affected part is the leg. The most
common cause of lymphatic obstruction is filaries. Filaries is
caused chiefly by the species Wuchereria. When you have
wherever it is located your skin will become rough
and thickened like the skin of an elephant.
Over 1 billion people in 73 countries are at risk of getting
elephantiasis, and there are over 120 million people who
already have it.
New research has determined that albendazole, which has
already become a standard treatment to fight intestinal
parasites, is 99 percent effect ...
