.... around the body, particulary to the bones where they can paues pain and disability. Estimates show that the cancer may have been growing in some men for up to 10 yearsbefore it causes symptoms and is diagnosed. Some men develop symptoms whereas others do not. In those who that do, the following symptoms are commonly found: BATHROOM TROUBLES: -Need to urinate frequently, especially at night -Sudden, incontrolable urges to urinate -Weak or interrupted urine flow -A burning sensation or pain when urinating -Blood in urine -Continuing pain in lower back, pelvis, or upper thighs BEDROOM TROUBLES: -Reduce .....

.... begun to explore the nature of very basic a-life formats called cellular automata (see AUTOMATA, THEORY OF) in the 1950s. Cellular automata are imaginary mathematical "cells" --analogous to checkerboard squares--that can be made to simulate physical processes by subjecting them to certain simple rules called algorithms (see ALGORITHM). Before his death, von Neumann had developed a set of algorithms by which a cellular automaton--a box shape with a very long tail--could "reproduce" itself. Another important predecessor of a-life research was Dutch biologist Aristid Lindenmeyer. Interested in the mathematics of plant growth, Lind .....

.... estimate the aircraft were approximately the size of a DC-4 airliner ( Jackson 4). This account was the first sighting to ever receive a great deal of media attention. This sighting gave birth to the phrase "flying Saucer" coined by a reporter named Bill Begrette. Although not the first UFO sighting in history, Kenneth Arnolds account is considered to be the first documented UFO sighting. The following day Mr. Arnold discovered that in addition to his sighting there were several others in the Mount Ranier area that same day (Jackson 6). When most of think of UFO sightings we picture an unemployed, half .....

.... is a mobile creature and it lives in northern Asia and is found as for north as the Arctic Circle. It's territory is more than four thousand square miles and it will keep that territory indefinitely, as long as the food supply lasts. The Siberian Tiger hunts very much but only about one tenth of the hunts are successful. It requires more than twenty pounds of meat per day. It is heterotrophic and it's diet consists mainly of deer, boar, bear and fish. The Siberian Tiger is a solitary animal. Males and females are only together during mating season. Females will only stay with their litter of two or three cubs for le .....

.... the respitory tract and the child's neurology (lethargy and malaise) form being bacterial or fungal, which is common amongst young children. A number of viruses cause respitory illness similar to the common cold, but are much more severe in intensity and wit frequently serious, and even fatal, complications. The best known of the group is Influenza (flu) virus. It can cause mild symptoms that are indistinguishable from those of the common cold, but in the more easily recognizable form it is ushered in by fever, cough, and what doctors refer to as malaise--chills, muscle ache, and fatigue. Pneumonia might be defined as any inflam .....

.... elements such as copper, manganese fluorine and zinc. Once of the most important is calcium. Calcium is used to build up your bones. It also helps to keep your teeth strong. About 90% of all calcium is stored in your bone's. It also helps with mussel contraction. Milk products such as milk, cheese and other stuff it the primary source for calcium. You should have about 1000mg's a day. Magnesium is also another important mineral. This mineral is in most foods. It is very important in containing healthy mussel cells. It also helps in forming bones. Sodium is another kind of mineral. Sodium is usually found in small but ok quant .....

.... Tigers use their tails for balance when they run through fast turns. They also use their tails to communicate with other tigers. Where did tigers come from? Tigers (and all other carnivores) are descended from civet-like animals called miacids that lived during the age of the dinosaurs about 60 million years ago. These small mammals, with long bodies and short flexible limbs, evolved over millions of years into several hundred different species, including cats, bears, dogs and weasels. Approximately 37 cat species exist today, including Panthera tigris, the tiger. Tigers evolved in eastern Asia, and while some of the earliest t .....

.... have flattened nails, but those of the marmoset are an exception. Except for the night-roaming durukuli of tropical America, monkeys are active during the day, moving frequently in bands in search of vegetation, birds' eggs, smaller animals, or insects to eat. Monkeys are highly social animals and are often organized in clans headed by an old male; these clans are rigidly defined in such species as howlers and baboons. As in all primates the brain is comparatively large. This feature, combined with the freeing of the hands and a well-developed vision, allows monkeys a great latitude of activity. Among the smaller New World form .....

.... simple steps. Another way of detecting breast cancer is with a mammography. This is an X-ray that scans in make up of the breast to show whether there are and tumors. This is the most effective type of detection to date. (Cancer Facts, Detection. National Cancer Institute) One disadvantage to using mammography is that with mammography, the x-ray picture sometimes detects substances in the breast that are not recognizable. (NCI ) This can cause unnecessary worrying if the substances are not recognizable. NCI is now working on improving the equipment that is available. An extension of the mammography is the digital mammogra .....

.... gas from the air and to use them in explosives. Soon after the war, these factories were used to absorb nitrogen gas and to be used as a fertilizer. This method was inexpensive and farmers were now actually making a profit. By 1985, farmers used approximately eleven million tons of nitrogen a year. This is eight times more than what farmers used in 1950. The most widely used fertilizer is pure ammonia. It is kept in liquid form under pressure in steel tanks. Three solid nitrogen are ammonium sulfate, ammonium nitrate, and ammonium phosphate. Two common phosphorus are superphosphate and triple superphosphate. Phospho .....
