.... the burning of fossil fuels. The smoke and fumes from burning these fossil fuels rise into the atmosphere and combine with moisture in the air to form acid rain. The main chemicals in air pollution that create acid rain are sulfur dioxide and nitrogen oxides. Acid rain usually forms high in the clouds where sulfur dioxide and nitrogen oxides react with water, oxygen, and oxidants. This forms a mild solution of sulfuric acid and nitric acid. These chemical reactions that change air pollution into acid rain can take from several hours to several days. Sunlight increases the rate of these reactions. Rainwater, snow, fog, and other forms of precipitation c .....

.... Unidentified Flying Object. Modern electronics and science have helped us in the search for an explanation of these mysterious floating objects. In actuality they haven't gotten us much further on the mission for proof of other living beings in the universe. But in a universe so incomprehensibly large that we no not even a boundary, I sincerely doubt that the human race is the only form of life. It seems certain scientists have come up with other hypotheses concerning UFO's. While all astronomers yearn for a concrete explanation on UFO's, their beliefs on their origin contrast. Many looking for a more scientific definition disregard UFO's as nothing mo .....

.... levels of knowledge, and since most people only know what they experience through senses, what we learn through our senses is not Wisdom. The reason behind this was Aristotle knew that knowledge obtained through the senses can only tell a person the "that" of anything and not the "why;" for example; We all know "that" fire is hot but do we know "why." We also know "that" water is wet but "why" is it wet. These were questions that nobody obtained the answers to but Aristotle was determined to know, and having this type of knowledge would truly earn the title of PAGE 1 Wisdom. Now finding the knowledge and answers would be very difficult but Aristotle believ .....

.... probes or markers for six plus the gender determining X and Y chromosomes. "What we're trying to decide now is whether to isolate probes for the other chromosomes, or whether we should utilize the eight we have," he says. Dr. Willard is currently negotiating with an American company to develop prenatal diagnostic tests, which, because the current tests are time consuming and technically difficult to do, are restricted to women over 35 and those who have a family history of chromosomal abnormalities. Prenatal tests using Willard's probes would be much simpler and faster to perform and could be available to all pregnant women who wish to take advantage o .....

.... so that people would be able to live there some day. Some products developed in NASA's space program that we now incorporate in our daily lives include the vacuum cleaner, pacemaker, pens that can write upside-down, and the zero-gravity training system. The vacuum cleaner was originally a great tool for astronauts in outer space. It is now a very helpful tool for cleaning our homes. The pacemaker is a form of life-support on spacecrafts, helping astronomers' hearts pump while they are outside of the Earth's atmosphere. It is used, on Earth, for those who's hearts have problems with pumping blood. Pens that write upside-down are used in space, where th .....

.... component of the ocean environment. In the following paper, I will provide a general overview of coral reefs and examine the alarming depletion of coral and their ecological symbionts in a process known as coral bleaching. As mentioned earlier, coral reefs are among the most diverse and productive of all communities on Earth. They are also the largest biological structures on the planet. The Great Barrier Reef, along the eastern coast of Australia, covers over 2000 kilometers and is said to be visible from the moon (Goreau, 1987). While the size of coral reefs can be enormous, their real impact is on a much smaller scale. Reefs function as food and shelter .....

.... 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 handling, storage, and disposal of the depleted uranium. When nuclear fuel is first loaded into a reactor, 238U and 235U are present. When in the reactor, the 235U is gra .....

.... acid is produced, there are three major plant locations that should be noted on account of their greater size. These are: (1) Inco. - Sudbury, (2) Noranda Mines Ltd. - Welland, and (3) Sulfide - Ontario There are a number of factors which govern the location of each manufacturing plant. Some of these factors that have to be considered when deciding the location of a Sulfuric Acid plant are: a. Whether there is ready access to raw materials; b. Whether the location is close to major transportation routes; c. Whether there is a suitable work force in the area for plant construction and operation; d. Whether there is suffi .....
