.... marsh gases, airplanes, lights of cars, birds, and many other objects as UFOs," (Kraske 22). Pranksters have also misled UFO investigation by doing actions that confuse and mislead humans. For example, they flash images of car headlights and city lights on the Earth. Pranksters also confuse people by tossing discs from tall buildings and taking pictures of spaceship models. One man was suspected of taking pictures of a realistic chicken-hatching machine. Human psychology has also played a role in the investigation of UFOs. An anonymous psychologist stated that, "When on .....

.... about animals that are used in good and bad experiments. When you hear about the treatment of some animals for research, you feel like forgetting about research. One such story was in 1988, three gray whales got stuck in freezing waters in Alaska, the whales were at risk of drowning because the holes in the ice that they were using to breathe were slowly freezing over. a large rescue was put together that ended up involving the National Guard and the U.S. and Soviet governments to get the whales free (Luke 87). Another story is of a mother cat that risked burning to death t .....

.... passwords is used. Anyone intent on gaining access to the Internet can repeatedly make guesses until the right combination is found, a simple but time consuming process made all the easier by programs which systematically try all character combinations until the correct one is eventually generated. User-IDs and passwords can also be trapped by finding security holes in programs; a person looking to abuse the Internet finds these holes and uses the information leaked through them for his or her own personal agenda. Even someone who has been entrusted with high-level network acc .....

.... Along with Matthias Jakob Schleiden a German botanist, Schwann proposed the cell theory. The cell theory has three parts: 1. All organisms are composed of cells. 2. Cells are the basic units of structure and function in organisms 3. All cells come from preexisting cells. The impact on science was very great due to the discovery of cells and the cell theory. Many or all things were effected by the discovery of cells, everything was looked upon in a different way. Some people still did not believe that all living organisms were made of tiny microscopic cha .....

.... normal breathing process, the blood stream absorbs oxygen from air in the lungs, while carbon dioxide passes from the blood to the air. When you hold your breath, the exchange of gases slows, as "stale" air in the lungs is no longer replaced by "fresh" air. Oxygen is actually removed from the blood stream during the exchange of gases. depending on how completely oxygen is replaced by helium, you may lose consciousness quickly and without warning - you may literally pass out while still standing. The usual result is an uncontrolled fall that can cause serious injury, eve .....

.... temperature for the past 150,000 years that suggest a direct association with carbon dioxide levels. In the past the temperature highs and lows have been in tandem with carbon dioxide level highs and lows, this does not seem to be a mere coincidence. Carbon dioxide currently accounts for 0.03% of the gas content within the atmosphere. However, it has a disproportionate impact on the earth's temperature. Thus, minor fluctuations in the percentage of atmospheric carbon dioxide will likely have a significant effect on the global temperature. The percentage of atmospheric carbon d .....

.... increase of CFCs in the atmosphere has been higher than any other greenhouse gas. By 1990 the increase was 4-12% a year. CFCs also destroy ozone - itself a greenhouse gas - their net effect on climate is unclear. The strength of the indirect effect of ozone depletion depends on variables such as temperature of the upper atmosphere and cannot yet be measured with any confidence. According to new research, however, it is possible that the indirect effect of CFCs cancels out some or all of the direct effect of their being powerful greenhouse gases. CFCs are .....

.... is also unparalleled. It can be shaped or extended into extraordinarily thin sheets. For example, one ounce of gold can be hammered into a 100 square foot sheet. Gold is the most reflective and least absorptive material of infrared (or heat) energy. High purity gold reflects up to 99% of infrared rays. Gold is also an excellent conductor of thermal energy or heat. Since many electronic processes create heat, gold is necessary to transfer heat away from delicate instruments. Gold alloy is the most tenacious and long-performing material available for protection of these tempera .....
