.... populated areas. In the United States in the early 1990's 50% of the population was on a coastal county.1 Although they shrink before reaching shore, wind generated waves have been spotted to be as high as 30 m (100 ft) in the middle of the ocean.2 In 1970 a major storm in the Bay of Bengal produced heavy seas that flooded regions of East Pakistan, killing about 200,000 people.3 River flooding can happen a number of ways. The causes are rain, snowmelt, and ice jams. Soil can not absorb as much water with continuos moistening. The longer that precipitation lasts the more water flows into streams as runoff.

.... area to volume ratio decreases so in this example it is very likely that the two flasks in question are different shapes. In this experiment the two flasks which will be used will different surface area to volume ratios as follows: 100 cm3 flask: Volume = 100, Surface Area = 115. Surface Area to Volume Ratio = 115 ---- : 1 = 1.15 : 1 100 500 cm3 flask: Volume = 500, Surface area = 330. Surface Area to Volume Ratio = 330 ---- : 1 = 0.66 : 1 500 As it is seen the ratio is lower in the 500 cm3 flask. This means that the rate of heat loss should be less than the 100 cm3 flask. Heat is lost by thr .....

.... alleged, the benefits of DDT far exceed the flaws. DDT was first synthesized in 1887 and patented as an insecticide in 1939 by a Swiss chemist, Dr. Paul Müller (Whelan 69). It initially became popular because of its effectiveness against insects, specifically clothes moths and parasites of both animals and plants. DDT was welcomed as a substitute for toxic insecticides like arsenic, mercury, fluorine, and lead (Whelan 70). It was used by the Allied troops during World War II in order to kill body lice without having harmful side-affects on humans. The elimination of the lice resulted in the absence of typhus fever (which was .....

.... and could guarantee that we could still fire our own nuclear missiles in our defense. Soon major schools and corporations threw their hats into the race for a network in which information could be sent electronically. Throughout the seventies a couple of schools developed their own network in which they could communicate with each other and devices were designed to make networks within offices possible using a technology called Ethernet. Throughout the eighties the newly designed internet was mainly used by science foundations, colleges, and the government as they worked together with growing computer and telephone companies .....

.... on the type of tides. High - water heights vary from 22 to 28 feet and low - water heights vary from 0 to 7 feet above chart data. Because of these semi - diurnal tides and the action of the St John River, slack water in the Habour occurs at approximately tides and not at high or low water as would be the case at other parts. THE RHYTHMIC RISE AND FALL In the Bay of Fundy, the tides are spectacularly large. While the rise and fall of sea level due to tides is the most apparent aspect, it is also the tidal currents that direct magnification of tides, and the sea level rises or declines are due to resulting convergences and dive .....

.... air pollution is thought to cause up to several thousand deaths and up to 20,000 hospital admissions every year. Acid rain is another serious problem, helped along with the increased usage of motor cars. The increased acidity of the precipitation is down to contamination by carbon dioxide, sulphur dioxide and nitrogen oxide, all of which the car is largely responsible for. During driving, a large percentage of lead is emitted into the atmosphere and although most of it is ultimately deposited on the ground, appreciable concentrations can enter the air and be transported considerable distances. Young children are permanently affe .....

.... were probably the best four hours of my adolescent life. When I was out on the kayak I saw so many killer whales it was unbelievable. We were in the midst of two whale pods numbering about 90 whales. I had heard that killer whales can attack people. Surprisingly, I was not afraid except for the fact of how cold the water was. It was so cold that if our kayak capsized both my father and I would have died in about 10 to 15 minutes from exposure to the freezing water. The experience was both frightening and exhilarating. My adrenaline was rushing and my heart was pounding so loud, I could hear it above the roar of the sea. Whe .....

.... language deficits such as aphasia and apraxia become prominent. Dysfluency, paraphasias, and bizzare word combinations are common midstage speech defects. In the severe stage the patient is gradually reduced to a vegetative state. Speech becomes nonfluent, repetitive, and largely non-communicative. Auditory comprehension is exceedingly limited, with many patients displaying partial or complete mutism. Late in the course of the disease many neuropsychological functions can no longer be measured. Also primitive reflexes such as grasp and suck emerge. Death usually results from a disease such as pneumonia which overwhelms .....

.... by forty to fifty percent without the use of on our crops. The FDA, EPA, and the Department of Agriculture try to ensure that the use of is necessary to the extent in which they actually are used by performing studies and proposing bills and laws to Congress. There is no dispute that are harmful. The purpose of is to kill certain fungi, plants, and even animals, so it seems only natural that they would have some effect on humans as well. An example of how these societies have helped to try and lessen the use of the more harmful is the Pesticide Food Safety Act of 1993. This bill is to try and be sure that the food people .....

.... one big, flat, spatula-like tail (Sentman 327). This feature made people confuse manatees with mermaids for nearly four centuries (O'Shea 66). Many biologists say that manatees possibly originated or evolved from ungulates such as elephants and cows because of the way that they are built, and certain features that they have in common. Like elephants, manatees have the peculiar half-moon shaped fingernails, and thick, wrinkled skin. Manatees also shares some traits with cows. The way the manatees spend all day lazily grazing on the ocean floor is incredibly similar to the behavior of cows at a pasture (Breeden 58). Manatees eat .....
