... 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 required 2,000 grams of chemicals to produce the same amount of energy. Another interesting point regarding this cell was the fact it had to be deliberately shut down. There was no sign of the r ...
... Other examples of folded mountains are the Rockies, Himalayas, Appalayas, and the Andes. Fault-block mountains are formed when one plate pushes or pulls away from another plate. In the Earth, hot currents of magma or molten rock may well up and crack the weakened crust above. As the crust cracks, blocks of rock rise or fall forming Fault-block mountains. Examples of these mountains are the Sierra Nevada in California and the Grand Tetons in Wyoming. Dome mountains are formed by the same kind of molten rock that forms Volcanic mountains. As magma comes up in a crack in the Earth’s crust, it does not come to the surface, but the molten rock pushes ...
... of the trash content everywhere. It is not fair to these animals whose food and shelter always gets contaminated. When these animals get killed, it breaks a part of the food chain. If an animal is taken out of the chain, the other animals that eat that one will go hungry, therefore killing them off too. Contaminated food has already happened to the food humans eat. For example, the Mad Cow Disease. This disease slowed the beef market down and it is easily happening in the other ocean creatures market. Humans have no right to kill what is not theirs, unless it is for food purpose only. Most humans do not realize that polluting the ocean kills animals, but the trut ...
... aggression they either dream about how aggressive they are or about the lack of aggression in their daily routine. Women, on the other hand, have typically been brought up to be more emotional than men. This up bringing has also affected the way women dream. ³Women are more likely to dial into their interior life whether awake or asleep² (Segell 42). This means that women will read into their more frequently then men. Researchers have found that problems that occur during the day either at work or home and are worked through in your sleep (Segell 42). While men would most likely look at these as nothing but a dream, women will try to face these prob ...
... death. Stratospheric ozone has been used for several decades as a tracer for stratospheric circulation. Initial measurements were made by ozonesondes attached to high altitude balloons, by chemical-sondes or optical devices, which measured ozone concentrations through the depletion of UV light. However, the need to measure ozone concentrations from the surface at regular intervals, led to the development of the Dobson spectrophotometer in the 1960s. The British Antarctic Survey has the responsibility to routinely monitor stratospheric ozone levels over the Antarctic stations at Halley Bay (76°S 27°W) and at Argentine Islands (65°S 64°W). Analysis of ozone ...
... was firewood. By the end of the 1800’s, the demand for energy was ever increasing and firewood around industrial centres was becoming scarce. This led to a switch to coal as the major source for fuel and energy. As well as powering steam engines coal became widely used for heating, cooking and industrial processes. Air pollution during the Industrial revolution was far worse than anything seen today. Apart from the smoke and fumes obscuring visibility, they also caused major health problems to the inhabitants of the industrial areas reducing life expectancies, predominantly with respiratory diseases. The simultaneous development of the internal combustion ...
... scope of uses, from the gathering information about companies, to personal blackmail. It’s used not only by individuals against other persons, but companies and even the nation as well. As the third wave, defined by Tofflers, becomes more widely spread across the nation and world we can only expect a far larger usage of such technological tactics, being used in the home, workplace, and even international politics. Schwartau’s definition of is, “the use of information, and information systems as both weapons and targets in a conflict,” (Schwartau 12). We are now living in a time when knowledge is power, and what is knowledge made up of? ...
... and natural catastrophes. Populations are even limited on the land that is available. Current policies on National Grasslands and other federal lands typically limit prairie dogs to small percentages of available potential habitat. Prairie dogs are essential to our prairie ecosystem. Many species dependent on prairie dogs for prey and habitat are diminishing in direct relation to the decreasing number of prairie dogs. Unlike other species, which have declined because of habitat loss due to human activities, the loss of prairie dog populations is a direct result of governmental and private landowner efforts to eradicate them. Prairie dogs and their environment ...
... A study shows roughly 80% of diseased individuals experience insomnia (depression.com 1). Possible problems may include: difficulty in falling asleep, waking up in the middle of the night with difficulty returning to sleep, waking up too early in the morning, brief periods of REM sleep, unusually long periods of stage 1 (light) sleep, or unusually brief periods of stage 3 and 4 ( deep, restorative) sleep (depression.com 1). Weight and depression are also commonly associated with each other. Many people begin loosing interest in eating which results in weight loss. Others may experience the opposite effect and gai ...
... she would pass it on to her child because she can only pass on one of the two chromosomes. If a male has hemophilia, he will have normal sons and all of his daughters will be carriers of the hemophilia disorder because all he can pass on is the defective X-chromosome. Males mostly have hemophilia, but women can also have hemophilia. This is extremely rare though because two defective X-chromosomes would be needed. In fact, the first proven case of women having hemophilia was not until the 1950’s (Bornstein 89). Female carriers are also at risk. These women are known as asymptomatic carriers and may suffer excessive menstrual bleeding ...
