.... performed at stratospheric altitudes. The Observatory will accommodate installation of different focal plane instruments, with in-flight accessibility, provided by investigators selected from the international science community. The Observatory objective is to have an operational lifetime in excess of 20 years. The SOFIA project is in the early full-scale stage. The start of detailed system design is anticipated in the Fall of 1996. The German Space Agency (DARA) is a partner with NASA in the SOFIA project. DARA will provide the telescope and NASA will provide the rest of the facility including the 747 aircraft, aircraft modifications, on-board mission control system, ....

.... the individual experiencing episodes of mania or elation followed by low mood or depression. The number of manic and depressive episodes varies greatly from person to person and most individuals experience "normal" periods between their manic and depressive episodes. Manic depression can send a person plunging from a high state, where one may believe one has superhuman energy and abilities, into a pit of despair, where it may seem as if the only way out is suicide. There are two types of bipolar, bipolar 1 and bipolar 2. Bipolar 1 is diagnosed differently than bipolar 2. Bipolar I is diagnosed when person has a manic episode and has had no depressive episodes in the past. Ho ....

.... to produce the equivalent amount of electricity produced from Uranium. The use of nuclear power opposed to burning fossil fuels has reduced carbon dioxide emissions by 2 billion tonnes per year, minimising the global warming effect on the atmosphere. Carbon dioxide is responsible for half of man made gases contributing to the Greenhouse Effect, and has sparked action from the UN Intergovernment Panel on Climate Change. Their consensus is a concern for the environment in the next century if fossil fuels continue to be used, even at present global levels. The Panel claims that for carbon dioxide to be stabilised to safe levels, a 50-80% reduction in all emi ....

.... process is exothermic, and can generate energy in one of two ways. Energy can be input in to a system and multiplied, or energy alone can be generated although in a much smaller amount. For example, one watt of energy can be input and 3 watts recovered. Some systems are capable of producing hundreds of watts per individual watt. The actual physics of the reaction is not completely understood. Some claim it is merely a chemical reaction not yet understood, while others are convinced it is a nuclear reaction. One example is a cell which used .04 grams of metal hydride. It produced 86 megajoules over a two month period. A similar chemical reaction would have requir ....

.... he found the ratio of the charge, e, to the mass, m, of the cathode-ray particles. He found e/m identical to those particles irrespective of the metal the electrodes were made of or the kind of gas in the tube. In 1909, RA Millikan, an American scientist, measured that charge. All electrons are found to be identical no matter their source or the method of liberating them from matter. From the values of e/m, and e, the mass of an electron was calculated to be .00055 amu. PROTON- Eugeen Goldstein used a Crookes tube with holes in the cathode, and observed that another kind of ray was emitted from the anode and passed through the holes. He discovered this in 1886. ....

.... the widow bird nestlings can grow up among their alien nestmates with no risk of being rejected by their foster parents. MASTERS OF DISGUISE Things aren't always as they seem, and nowhere is this more true than in nature, where dozens of animals (and plants) spend their time masquerading as others. So clever are their disguises that you've probably never known you were being fooled by spiders impersonating ants, squirrels that look like shrews, worms copying sea anemones, and roaches imitating ladybugs. There are even animals that look like themselves, which can also be a form of impersonation. The phenomenon of mimicry, as it's called by biologists, was first no ....

.... Conclusion On June 24th, 1947 while searching for the remains of a downed Marine C-46 transport, lost somewhere in the Mount Ranier area, a young Idahoan businessman named Kenneth Arnold spotted something that would change his life forever. Just north of his position flying at an altitude of 9,500 feet and an unprecedented airspeed of 1,700 mph he spotted nine circular aircraft flying in formation. According to his 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 ....

.... troposphere which is between zero and fifteen kilometers in altitude and has tempera- ture ranges from two hundred to two hundred ninety kelvins. The second is the stratosphere which ranges from fifteen to approxi- mately fifty kilometers in altitude and has temperature ranges from two hundred to two hundred fifty kelvins. The third level in the atmosphere is mesosphere. This level ranges from fifty to eighty-five kilometers in altitude and has temperature ranges between one hundred eighty and two hundred fifty kelvins. Finally, the thermosphere is the final level in the atmosphere. It's range is eighty- five to one hundred forty kilometers and also temperatures as high ....
