... acidic lakes reported is Little Echo Pond in Franklin, New York. Little Echo Pond has a pH of 4.2. Lakes and streams in the western United States are usually not acidic. Because of differences in emissions and wind patterns, levels of acid deposition are generally lower in the western United States than in the eastern United States. This chart shows that not all fish, shellfish, or their food insects can tolerate the same amount of acid: Generally, the young of most species are more sensitive than adults. Frogs may tolerate relatively high levels of acidity, but if they eat insects like the mayfly, they may be affec ...

... Adrenaline affects many different types of tissues throughout the body. The release of adrenaline prevents hypoglycemia (low blood sugar), by binding adrenergic receptors in the hormone releasing cells of the pancreas. Epinephrine is called the “fight� or “flight� hormone. The actions of epinephrine and norepinephrine are generally similar, although they differ from each other in their effects. Norepinephrine constricts almost all blood vessels. Norepinephrine is formed by intravenous infusion to combat the fall in blood pressure associated with types of shock. Norepinephrine is formed in the bo ...

... In a third method the ovum is fertilized within one woman's uterus and then transferred to the body of another woman. Eggs can now also be removed from a woman's ovaries and placed in her fallopian tubes along with spermatozoa, thus allowing for normal fertilization. Many times anonomus donors are used. Donors can be matched by factors such as race, color of eyes, hair and other physical characteristics, and are screened for conditions such as AIDS, gonorrhea and other STDS. Even though freezing sperm doesn't seem to affect a pregnancy, it reduces the sperm's movement and influences the success rate of . About ...

... that in the medical management of childbirth, the experience of the mother is viewed by physicians as pain: pain experienced and pain to be avoided.1 Having experienced childbirth ourselves, we have great compassion for women in painful labors. However, we also feel a responsibility to mothers and their babies to explore issues concerning the use of epidural anesthesia in labor issues that are seldom discussed prenatally. Several factors make the use of epidurals potentially hazardous. The Physician’s Desk Reference cautions that local anesthetics – the type used in epidurals – rapidly cross the p ...

... parasitic nature of war through out the book. In one particular section, Tim O'Brien returns to Vietnam with his daughter. Twenty years had gone by, but it seems as though all of his thoughts are geared back to the time he had spent in the jungle so long before. The two of them travel all over the country, but before their departure, he returns to the field where he feels he lost everything. On this list he includes his honor, his best friend, and all faith in himself. For O'Brien, evidence of the parasite is not solely in his return Vietnam, but rather a constant personal preoccupation that seems to flow through t ...

... possible therapeutic uses of Ergot. Hoffman continued his experiments, but never came in contact with the crystals until1943. (LSD can be absorbed through the skin.) Hoffman then sent LSD around the world to be tested and investigated to find medical uses. Lysergic acid deviates were found to relieve migraines and control postpartum hemorrhage because it causes veins to contract, but also caused gangrene of the limbs, and so further experimentation with the drug was abandoned. In the late 50's, however, LSD was used by the CIA as an interrogation drug for spies. However, it was proven to be unreliable and was ...

... one tenth to one third of the population. If we accept the smallest estimate, that's a lot of tossing and turning. These estimates are usually based on the number of serious cs, the definition of which varies considerably. Some doctors define cs as those who cannot sleep at all; other are willing to categorize cs as all those who merely complain about their sleep. The currently accepted definition, to become known as DIMS (Difficulty Initiating or Maintaining Sleep). Several surveys have tried to pin down the exact cause of sleep problems. Of 1,000 households, one third had someone with current problems and in 4 ...

... this catchy name has caused people to dream up incredible uses for this technology including using it as a sort of drug. This became evident when, among other people, Timothy Leary became interested in VR. This has also worried some of the researchers who are trying to create very real applications for medical, space, physical, chemical, and entertainment uses among other things. In order to create this alternate reality, however, you need to find ways to create the illusion of reality with a piece of machinery known as the computer. This is done with several computer-user interfaces used to simulate ...

... Claude Maechling and Richard Zare, dissected three meteorites that were about 2 to 8 millimeters long and found trace elements of a big mumbo jumbo word— polycyclic aromatic hydrocarbons. That pretty much means that there once was a warmer climate and maybe even lakes or oceans. Life on Mars is now a real idea. The climate of Mars about 3.8 billion years ago was much similar to the young Earth. Microbes and bacteria probably sprouted everywhere in the warm and wet climate. Although now we only see a cold red planet, which was probably due to a collision of an astroid that would have set back the evolution p ...

... two competitors organized to achieve their goals in space showed their basic differences. The United States had separate civilian and military agencies, and only the military space programs were secret. Civilian space activities, especially , were openly publicized for the world to see. On the other hand, in the Soviet Union all space programs blended into a secretive military-industrial bureaucracy. Launches were not announced in advance, and only the successes were publicized. (Baker 158-161). During the early years of the Space Race, success was marked by headline-making, historical "firsts." Some of these f ...
