Alcoholism 4
.... the stomach can also influence the blood alcohol level (Kestler 7).
In a one-hundred and sixty pound person, alcohol is burned at the rate of one drink every two hours. The more rapidly alcohol is ingested, the faster the peak blood alcohol level will be reached. When a person drinks faster than the alcohol can be burned, the drug accumulates in the body, resulting in higher levels of alcohol in the blood. The more body muscle a person has in relation to fat, the lower the blood alcohol concentr .....

Alternate Energy Sources
.... time, we will learn about this new energy source so we can use it to power the future.
Fusion Power
Fusion Power is probably the biggest known Alternate Energy Resource. Fusion is the joining of the nuclei of two atoms to form the nucleus of a heavier element. It occurs mostly with hydrogen and other light elements. Fusion reactions, also called thermonuclear reactions, release a great deal of energy. Scientists are still conducting experiments on ways of harnessing Fusion so we can use it a .....

Alternative Energy Sources
.... to help offset the exorbitant cost of such an undertaking, the federal government has given tax credits to companies of medium- to heavy-duty fleets that either convert their current vehicles or purchase new ones. As well, smaller, light-duty fleets, such as those used by police departments, will begin switching over to alternative fuels by the year 2001. Such fleets will be required to use natural gas, propane, ethanol, methanol or electricity.

Congophilic Angiopathy is the technical name that neuropathologists have given to an abnormality found in the walls of blood vessels in the brains of victims of Alzheimer's disease. These abnormal patches are similar to the neuritic plaques that develop in Alzheimer's disease, in that amyloid has been found within the blood-vessel walls wherever the patches occur. Another name for these patches is cerebrovascular amyl .....

new brain cells will probably result in a more successful strategy
than attempting to grow the cells outside the body and then
placing them back into the brains of patients, as some scientists
have suggested.
Goldman, of Cornell University Medical College in New York,
and colleagues surgically extracted brain cells from the
hippocampus of eight living male patients, ranging in age from 5 to
63 years, while they unde .....

Despite odds, accidents do occur" (28), which can result in deformities and illness. The only way this can affect a child is if the mutation occurs in either the sperm or the egg. Human causes of mutation include x-rays, nuclear fallout, and toxic chemicals. The environment can cause mutations as well. Sources of these are exposure to the sun's radiation an .....

This can also be verbally, intellectually, physically, and aesthetically. In our society we have always praised the athletes that achieve the most amazing physical feats or that have achieved cosmetic perfection. Lets face it, having large muscles enhances confidence, strength, and physical attraction from the .....

Anatomy & Physiology
The many nuclei of skeletal muscle fiber are located underneath the sarcolemma, which is the fiber’s plasma membrane. Thousands of invaginations of the sarcolemma, which are called T Tubules, Tunnel from the surface to the center of the muscle fiber. These T Tubules are open to the outside of the fiber and are filled with .....

In late Precambrian time this super continent began to rift apart under the tensional forces producing the Catoctin rift basalts that can be observed in the Shenandoah. As they rifted apart, they created a growing ocean called the proto-Atlantic or Iapetus after the father of Atlas, for whom the Atlantic Ocean is named. Towards the end of the Precambrian, the tensional forces changed to compression and subduction began. Volcanic islands gre .....

Mechanical filtration aids in biological filtration in two ways, the water is filtered through a medium that helps dissolve the ammonia and nitrites into smaller pieces easier for the bacteria to convert, and filter out bigger objects from the water such as excess food. Generally the filter media is activated carbon within a floss cartridge.
The ph value in a tank doesn’t generally matter for basic to medium aquarium hobbyist. As long as it is between 6.5 and 7.2, ph range .....

.... From the visible remains of the bison, we can estimate from the skeletal remains of the bison that the total meat was 60,000 pounds and the total amount of people capable of butchering the bison would be 150, thereby relating the artifacts to past human behavior.
Archaeologists also study patterning in time and space; time, being vertical and space being horizontal. The time of the butchering in the Olsen-Chubbuck site was calculated from the age and sex composition of the bones and dated to be early .....

This is the ordinary, stable form of the element. There are two other allotropes (solid forms)--yellow arsenic and black arsenic, whose modifications have no metallic properties. Occasionally found free in nature, arsenic usually occurs in combination with sulfur, oxygen or certai .....

Aspirin: from willow tree to Nobel Prize
Aspirin's active ingredient, acetylsalicylic acid (ASA), is the commercially synthesized form of a naturally occurring compound whose uses can be traced back 2,000 years. The compound, called salicin, is found in the white willow tree. Around 200 B.C., Hippocrates, the Greek physician, discovered that chewing on willow bark could relieve pain and fever.
Although ASA was a proven pain reliever, no .....
