.... has found many functions within the body. Nitric oxide enables white blood cells to kill tumor cells and bacteria, and it allows neurotransmitters to dilate blood vessels. It also serves as a messenger for neurons, like a neurotransmitter. The compound is also accountable for penile erections. Further experiments may lead to its use in memory research and for the treatment of certain neurodegenerative disorders. One of the most exciting discoveries of nitric oxide involves its function in the brain. It was first discovered that nitric oxide played a role in the nervous system in 1982. Small amounts of it prove useful in the .....

.... much research supports the conclusion that pollution from coal-powered electric generating stations in the midwestern United States is the ultimate cause of the severe acid-rain problem in eastern Canada and the northeastern United States. Nor are the destructive effects of acid rain limited to the natural environment. Structures made of stone, metal, and cement have also been damaged or destroyed. Some of the world's great monuments, including the cathedrals of Europe and the Colosseum in Rome, have shown signs of deterioration caused by acid rain. Scientists use what is called the pH factor to measure the acidity or alkalinit .....

.... These results support the idea that the costs of muscular force production determines the energy cost of running and suggest that bipedal runners use more energy for a given rate of force production because they require a greater volume of muscle to support their body weight. Key words: locomotion, energetics, bipedal, bird, muscle force. Introduction The question of wither more energy is required to run on two or four legs was addressed 100 years ago when Zuntz (1897) performed some of the first measurements of metabolic energy consumption in running animals. He found that horses used less energy than humans to m .....

.... Diagnosis can be difficult because many of the critical diagnostic features change with age. It is most difficult to diagnose in newborns and adults. Reaching an FAE diagnosis is even more difficult because only some of the symptoms are present, and possibly not as visible. This disorder cannot be detected by genetic testing because the damage is done after the baby is born. It is not known how much a pregnant woman can safely drink without damaging the fetus, although heavier drinking increases the likelihood of damage. Also, there does not seem to be any time during pregnancy when it is safe to drink. As a result, it is ge .....

.... alternative fueling. Having to smell the awful odor emitted day after day from his fleet of forty-seven buses, Cromwell (Silverstein 10) encourages the changeover. Phil Bostley, Mayor of Indian Wells, a subsection of Coachella Valley, agrees wholeheartedly by saying petroleum-base fuels will go the way of the buggy whips back in the 1930's (Silverstein 10). Fortunately, for those who run such fleets, a mandate issued by the Energy Department required operators to "begin purchasing alternative fuel vehicles" (Silverstein 10) as of September 1, 1996. In an effort to help offset the exorbitant cost of such an undertaking, the fed .....

.... will be working with live animals. Analysis and Conclusion: 1. The person is not wearing safety goggles and he isn't really paying close attention. Safety goggles are vital when you are working with fire. 2. She is pointing the vial towards herself. Whenever you are working with heating liquids, the vial should never pointing towards you. 3. The person is heating a liquid with a top on the beaker. Whenever you are heating a substance, there should never be a top on the liquid. 4. The lady is drinking out of the beaker. You should never do that. You also should never eat at a lab station Conclusion: In this lab, I lea .....

.... fractal geometry a useful and valid tool. New insight into the natural world is just one of the results of the increasing popularity and use of fractal geometry in the last decade. What are fractals and what are they good for? Scientists in a variety of disciplines have been trying to answer this question for the last two decades. Physicists, chemists, mathematicians, biologists, computer scientists, and medical researchers are just a few of the scientists that have found uses for fractals and fractal geometry. Ecologists have found fractal geometry to be an extremely useful tool for describing ecological systems. Many population .....

.... differences between graphite and are accounted for by the conditions in which they are created. form over long periods of time, between 100 km and 200 km below the surface. At this great depth, carbon gets a chance to cool very gradually, forming diamond crystals. When volcanic eruptions occur, magma carries the up to the surface of the earth. Kimberlite lavas carrying erupt at anywhere between 10 and 30 km/hour and increase their velocity to several hundred km/hour within the last few kilometers. (Pough, 44) At the surface, this lava cools and turns into Kimberlite rock. That is why are often found in kimberlite, a volcanic .....

.... and industry-processes and products. The majority of economic inventions collaborate with one another; a lot of things were invented to make other inventions work. Another major reason people invent is to satisfy military needs. During war times engineers, scientists, and inventors are brought together and their only duty is to invent military weapons. The weapons that the scientists come up with have to be more powerful and destructive than the enemies, with both sides striving to be the best. War has its negative effects on the world, but it also leads to many useful and positive inventions, such as nuclear energy an .....

.... valve in his heart. This scared a lot of people and the recreational uses of steroids decreased. With the dangers of steroids well-known people started looking for other substances to give them an edge. Bee pollen, carnitine and chromium picolinate, were among the things people tried. Of course none of these worked. But now there is a product on the market that has been proven to significantly enhance athletic performance in the areas of power, strength, and muscle mass. This substance is Creatine Phosphate.5 ABOUT CREATINE When the body performs exercise or work, there is obviously an expense of energy that is burnt. There are .....
