- 4421: Cryogenics and the Future
- ... magnetically levitated trains, energy storage, motors, and Zero-Loss Transmission Lines. Also, superconducting electromagnets are used in Particle Accelerators, Fusion Energy Plants, and Magnetic Resonance Imaging devices (MRI's) in Hospitals. Furthermore high-speed cryogenic computer memories and communication devices are in various stages of research. This field has grown immensely since 1986 as you can see and will probably keep growing. The second subject related to cryogenics is Superfluidity. Superfluidity ...
- 4422: Black Holes
- ... This telescope has just recently found what many astronomers believe to be a black hole, after focusing on a star orbiting empty space. Several pictures were sent back to Earth from the telescope showing many computer enhanced pictures of various radiation fluctuations and other diverse types of readings that could be read from the area in which the black hole is suspected to be in. Several diagrams were made showing how ...
- 4423: Avalanches and Landslides
- ... avalanches because they are controlled with explosives and artillery. In a back-country areas it is possible to predict avalanches because the forecast relies on experience of the person making the observation. There are no computer models available to predict avalanches and therefore predictions are only accomplished by repetitive observations and knowledge of snow properties. Due to difficulty in reliable predictions method areas of avalanche hazards must rely on controlling or ...
- 4424: Vivisection
- ... done to establish safety levels for humans of known toxic substances (1:40). Although testing might seem like the most efficient way to gain knowledge in these areas, alternatives exist. The use of slides, films, computer programs, and models can fulfill the same job without any harm. For example, in vet schools the symptoms of strychnine poisoning were demonstrated by poisoning dogs and then put on a video tape. On the ...
- 4425: Temagami
- ... protesting and governments always hold the policy of being more willing to listen to the legal protesters than lawbreaking troublemakers. Knowing such, some might wonder as to the reasoning behind such a clearly premeditaited group crime. The answers are varied however, looking at the effects of the disobedience, one comes to mind. Media. Those of the second view towards civil disobedience see it as a means of voicing their concerns to ...
- 4426: Changing The Motor Oil Of A Ca
- ... you don't have an owner's manual, just ask hte person working at the auto parts store, and he'll be able to look up all the information pertainiung to your car on his computer. Before even looking under the hood, make sure that the engine's temperature isn't high. You want the engint to be nice and cold so that you don't burn yourself. Make sure that ...
- 4427: Management Techniques For The Red-Cockaded Woodpecker On Federal Lands
- ... Reed et al. (1988) study indicate that CST may be generally used as an index, but further research is necessary to establish a universal technique to estimate red- cockaded woodpecker populations. The development of sophisticated computer programs and topographical analysis techniques may make assessment of red-cockaded woodpecker habitat and species abundance more accurate and less time consuming (Ertep and Lee, 1994; Reed et al., 1988). These advancements in geographic analysis ...
- 4428: Environmental Pollution
- ... exceeding 50,000 have some degree of air pollution. Burning garbage in open dumps causes air pollution Scientist have discovered that over the South Pole the ozone has a high level of ozone depletion. A computer-enhanced map, taken from satellite observations of ozone levels in the atmosphere over the South Pole, shows the region of ozone depletion that has begun to appear each spring over Antarctica. When you look at ...
- 4429: Death of a Planet
- ... If the car is releasing a high level of hydrocarbon emissions a video camera takes a picture of the car's license plate, and sends the license plate number and the emissions data to a computer (1 factsheet, OMS-15). Then the owner of the car is notified about the polluting car, and they are required to have the problem fixed (2 factsheet, OMS-15). If remote sensing devices are used ...
- 4430: Cfcs Cause Deterioration of the Ozone Layer
- ... liquid coolants for refrigerators and air conditioners. Several other Cfcs work well as aerosol propellants, in manufacturing foam, and in making Styrofoam containers. Furthermore, others are being used for cleaning delicate electronic equipment, such as computer chips and circuit boards. Moreover, these Cfcs appeared to be the perfect industrial chemical because they were, seemingly, completely safe for people and the environment. However, two scientists, F. Sherwood Rowland and J. Molina became ...
