Tundra And The Artic

... Tundra. The High Arctic Tundra is located farther north and encompasses the Arctic circle as well as most of the western Northwest Territories. Generally though since climate more or less corresponds to vegetation zones, the Tundra is located in Arctic climate areas. Temperature The Tundra suffers a very harsh climate. Because of this fact most of the area remains barren save for a few shrubs and lichens. It's winters last from 8-10 months and the summers are cool and short. Also due to the fact that much of it's territory is located within ...

B E C: The New Phase Of Matter

... 1995, scientists at the National Institute of Standards and Technology and the University of Colorado were the first to uncover the BEC. They magnetically trapped rubidium atoms and then supercooled the atoms to almost absolute zero. The graphic on the cover shows the Bose-Einstien condensation, where the atom's velocities peak at close to zero velocity, and the atoms slowly emerge from the condensate. The atoms were slowed to the low velocity by using laser beams. The hardware needed to create the BEC is a bargain at $50,000 to $1000,00 ...

Chance Or Planning

... scientific research. Such is the case with Charles Darwin, James Watson and Francis Crick. All three of these men were extremely intellectual, but their intellect only contributed partially to their success. Intellect and planning, combined with chance and luck contributed to their overall success. People take chances on a daily basis. If you actually stop and think about it, life is one big game of chance. It is by chance that we are born, that we continue to survive, and that we will eventually die. Some people feel that this cycle ...

The structure on the also helps them in some way. It has strong limbs which makes it able to swing from tree branches. Males way up to 90 pounds so it needs strong limbs.

The also has very strong legs, like u ...

Genetic Cloning

... cloning in the 90s has developed to the point where manipulation of human D.N.A is a very real prospect and many issues surrounding it must be addressed. These issues and the positive and negative influences on our society will be discussed herein, concentrating on selective breeding, genetic engineering, the identity of ‘clones’, enhanced cell growth products and production of spare body parts. Firstly, selective breeding throughout the ages has served humanity in many ways. The origins of cloning lie in the agricultural history of human ...

Hurricanes

... not know how this happens. But when it does, it's the first step in the birth of a hurricane. With the lid off, the warm, moist air rises higher and higher. Heat energy, released as the water vapor in the air condenses. As it condenses it drives the upper drafts to heights of 50,000 to 60,000 feet. The cumuli become towering thunderheads. From outside the storm area, air moves in over the sea surface to replace the air soaring upwards in the thunderheads. The air begins swirling around the storm center, for the same reason that the ...

This means that we [must] exercise caution, and special concern for natural values in the face of such uncertainty and respect the 'precautionary principal'." - Ontario Minister of Natural Resources, 1991 The History of the Forest Forests have long been recognized as having vast power, both through their potential and how it has been viewed by humans, ...

Monosaccharides

... contain five or six. The most important pentoses include xylose, found combined as xylan in woody materials; arabinose from coniferous trees; ribose, a component of ribonucleic acids and several vitamins; and deoxyribose, a component of deoxyribonucleic acid. Among the most important aldohexoses are glucose, mannose, and galactose; fructose is a ketohexose. Several derivatives of are important. Ascorbic acid (vitamin C) is derived from glucose. Important sugar alcohols (alditols), formed by the reduction of (i.e., addition of hydrogen to) a ...

Pulmonary Agents

... can result in varying degrees of pulmonary edema, usually after a symptom-free period that varies in duration with the amount inhaled. Chemically induced acute lung injury by these groups of agents involves a permeability defect in the blood-air-barrier (the alveolar-capillary membrane); however, the precise mechanisms of toxicity remain an enigma. The U.S. produces over a billion pounds of phosgene (CG) per year for industrial uses; however, we do not stockpile this agent for military use. Perfluoroisobutylene (PFIB) is a toxic pyrolysis pr ...

Dementia

... course. Delirium is an acute transitory disorder. By contrast is a long term progressive disorder (with the exception of the reversible s). The course of AD can range anywhere from 1.5 to 15 years with an average of about 8.1 years (Terry , 1988). AD is usually divided into three stages mild, moderate, and severe. Throughout these stages a specific sequence of cognitive deterioration is observed (Lezak, 1993). The mild stage begins with memory, attention, speed dependent activities, and abstract reasoning dysfunction. Also mild languag ...

Cloning

... I believe that cloning humans is what the human race needs to advance. Humans would be stronger, smarter, and more perfect. Scientists could remove bad genes from the parents and replace it with a good one. If one of the parents had a bad gene or hereditary disease this could be removed from the embryo and replaced with another "clean" gene. This process is called embryo screening it is used to determine if the child has received the defective gene. Several embryos could be cloned, then the DNA from one of the embryos would then be rem ...

Nuclear Waste Management

... uncontrolled reaction, which in turn caused a steam explosion. The reactor's protective covering was blown off, and approximately 100 million curies of radionuclides were released into the atmosphere. Some of the radiation spread across northern Europe and into Great Britain. Soviet statements indicated that 31 people died because of the accident, but the number of radiation-caused deaths is still unknown. The same deadly radiation that was present in this explosion is also present in spent fuels. This presents special problems in the ha ...
