... fire was moving ionals throughout the U.S. In other words, the present emerging technology is a lot more parochial (meaning practical) than political - a refreshing thought. "Honey, your fire has escaped.!" "There's no guarantee you'll not get a big rip," (see terminology sidebar, page 57) says a Forest Service fire officer on the eastern seaboard. "When you're messing with fire, there's always a chance one will escape," echoes his counterpart in California's Sierras. "The fuels are tricky..." adds Ron Meyers, who directs prescribed fires for The Nature Conservancy from his base in Florida. Such concerns are real. Paul Tine, acting Forest Service fuels specialist ...
... feet) At this point s would be broken down by short-wavelength ultraviolet radiation from the sun. This radiation is the one which would not reach the lower atmosphere in large amounts because of the ozone layer. When these s do brake down, they released atomic chlorine which then would react with the ozone and convert it back into plain oxygen. The even worse part of all this is that these chlorine molecules do not become inactive after the first reaction with the ozone and would be available to destroy more ozone molecules. Thus this process would be the function of a catalyst; a single chlorine atom involved in a chain reaction to destroy many ozone molecules. ...
... 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 firsts included the first satellite, the first robotic spacecraft to the Moon, the first man in space, the first woman in space, and the first spacewalk. To the chagrin of the United States, each of these early firsts were achieved by the Soviet Union, thus sparking the United States to not only catc ...
... for theoretical explanations of the star. Some of the most recent tools that have been invented to help study the sun are the coronagraph, the spectroheliograph, the magnetograph, and the spectrograph. These tools have enabled us to better understand the magnetic field of the sun and individual characteristics of the sun. Pictured above is Galileo Composition of the Sun The radiation that Earth receives from the sun is quite remarkable. The radiation that we receive varies less than 1% over a period of twenty four hours. However this less than one billionth of the radiation given off by the sun. This energy comes from deep with in the sun. ...
... sexual orientation, there is a great possibility of that trait being passed down from generation to generation. Experiments conducted led to the possible conclusion that the region Xq28 carries a gene influencing male sexual orientation. However, there are a few flaws to their interpretation of the results. Among them are stated in the article. A replication of the experiment is necessary, the separation of the particular gene has not been achieved, and the importance of the region has not yet been determined. Moreover, the supposed gene that influences homosexuality suggests that it acts indirectly on the choice of their sexual orientation. LeVay and Hamer ...
... again they might also sleep much less than normal. A person with depression doesn't realize and most of the time has no control whatsoever over these feelings. They have no idea that what is wrong with them is that they have depression. They might put the blame on some other stressful thing or even other people. Changes in the level of energy a person has can be caused by depression. One possible reason for this ties into their eating and sleeping habits. If a person starts to eat less, or sleep less they will notice a drop in how much energy the have. Some people with depression may become edgy or fidgety. Also the people may become very easily ups ...
... and a growing number of participants. Theoretical studies of a-life, however, had been in progress long before the 1980s. Most notably, the Hungarian-born U.S. mathematician John VON NEUMANN, one of the pioneers of computer science, had 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 au ...
... and other organisms accumulate, along with sand and other debris, to form the backbone of the reef. Over tens of thousands of years, chemical and mechanical changes turn the reef into true rock. The body of a coral animal consists of a polyp, which is the living portion of the coral. A polyp is a hollow, cylindrical structure attached at one end to a surface, the other end is a mouth surrounded by tentacles which gather food and can sting prey to paralyse it. Polyps live in colonies, which grow from 1 to 7 inches, depending on the species. Coral polyps are classified as animals. Microscopic algae live within the animal tissues in a symbiotic relationship. The ...
... feet of hydrogen and is broken down and releases gas into the second chamber where it goes to the engine for use. There are many ways to get pure hydrogen out of many compounds using methods such as electrolysis and chemical reactions. One of the easiest ways is using a chemical reaction. Simple chemicals (aluminum,sodium hydroxide, and water) can be reacted in the home to produce heavy hydrogen to power your furnace or your hot water heater . No electrical power at all is required. The reaction also gives off a tremendous amount of heat. Even the waste heat could be captured for heating the house. The resulting sodium aluminate is harmless and could be collected ...
... The order possesses three family which consist of about 82 species. These sharks are characterized by their slender, cylinder-shaped bodies, long snouts with shortened mouths. HEXANCHIFORMES: The Hexanchiformes or cow sharks, comprise of two families. Recognized by their six or seven pairs of gill slits, there sharks can often be found in deep water. The frilled shark (CHLAMYDISELACHUS ANGUINEUS) who's appearance is quite unmistakable due to it's "eel" like appearance, is perhaps one the strangest shark that exist today. FOSSIL RECORD: Shark fossil record is fargmentery at best. Most fossils found so far consist of nothing but teeth in some cases a few vertebra ...
