.... the change in volume for each degree of rise or fall in temperature is the same. The use of mercury in the thermometer instead of alcohol was done by Gabriel Daniel Fahrenheit in 1714. It was also used in vacuum pumps, barometers, and electric rectifiers and switches. Mercury is used in a mercury-vapor lamps which are used as a source of ultraviolet rays in homes and for sterilizing water. Mercury-vapor is also used instead of steam in the boilers of some turbine engines. Mercury is sometimes used for amalgamation. Amalgamation is a metallurgical process that utilizes mercury to dissolve silver or gold to form an amalgam. Th .....

.... of fungi have been reported in Arctic and Antarctic areas (some molds, after all, thrive on refrigerated food). There are about 50,000 known species of . Although any single typical may not be uniform in appearance--a mushroom, for example, has a cap, stem, and rootlike components--it has, in fact, a uniform structure throughout. The typical consists of a mass of tubular, branched filaments, or strands, called hyphae (singular, hypha). The mass of hyphae is called the mycelium, and it is this that makes up the thallus, or body, of the . In order to grow, the mycelium uses the organic matter, either living or dead, in its en .....

.... simply said is the compost made from the millions of dead animals and plants of the forest. When things such as leaves and animals die their remains are quickly broken down by a limitless amount of tiny organisms. Some insects that do just this sort of thing include: beetles, ants, termites and a host of others. With all of this death happening so quickly you would expect a sort of rotten smell to be in the air. This, however, is not the case. This is simply because everything that is dead in the forest is broken down so fast. One example of how true this is would be to kick a fallen tree. Chances are it would crumble to pieces bec .....

.... and the shotgun mic. The Omnidirectional Microphone comes in many different shapes and sizes. They are used when the background sound is normally low. They usually work by pointing the mic directly at the source of the sound. This mic is not good for loud background sound because the mic might not be able to distinguish between the different sounds. The Lavalier Microphones are small mics that have a more unidirectional pick up pattern which means that it has a limited reception range. These mics are attached to the reporters clothing or the subjects near the lapel level. When used in this manner they provide a very good mic, .....

.... prevent or cure illness. The more rigid and restrictive the policy provisos, the more assurance for the companies that they will maximize their bottom lines. Therefore, patients of alternative therapies as well as doctors must show that such unconventional treatment provides relief and prevention of illness. “The total projected out-of- pocket expenditure for unconventional therapy plus supplements(such as diet pills and megavitamins)was 10.3 billion dollars in 1990. This is comparable to the out-of-pocket expenditure for all hospital care in the United States in 1990($12.8 billion), and it is nearly half the amount spe .....

.... that still exists today. The immense heat from the magma (approximately 2700(C) causes convection in the mantle (Figure 1). Convection is caused by non-uniform temperature in a fluid and density differences. This continuous convection is the cause of plate movement. Each complete cycle, called a convection cell, drives the plate in the direction of the cell. How does a 'solid' mantle move? The mantle may be solid but, as with most solids, it will deform if long term stress is applied; "...like Silly Putty which seeps into the rug when left unattended, mantle material flows when subjected to small long-term stresses."1 .....

.... to such an extent that it does not filter out the sun's invisible and dangerous ultraviolet rays " ( Jones, 1992, p.36 ). Such a scenario would drastically alter society and the environment. Ozone depletion has been described as " potential catastrophe " and " a planetary time - bomb " ( Way, 1988, p.9 ). The four main areas affected by a depleted ozone layer and thus by the corresponding increase in harmful ultraviolet radiation are agriculture, wildlife, the environment, and human health. A depleted ozone layer has a profoundly negative and potentially devastating effect on humanity and its surroundings. From an agricultu .....

.... rediscovered by Charles Davenport in 1901 that the ideas of modern was given any credibility.4 Davenport conducted experiments that proved what Mendel had said years before in his laws of genetics. Davenport, however, took it another step. He extended Mendel’s laws to include characteristics such as pauperism, alcoholism, and the popular term of the day, “feeblemindedness.”5 Davenport also connected behavior to race, class, and pedigree. While all of Davenport’s ideas were up to date with all current research, such as his conclusion that characteristics such as what he called “thalassophilia,”6 or the love of .....

.... reduced their species. A long time ago the early European settlers at the Cape of Good Hope realized that penguin eggs were good for eating and over the years millions of penguin eggs have been collected greatly reducing the population of the African penguin species, and even to make things worse they started the practice of destroying any incubated eggs so that there would be fresh ones when these collectors paid their next visit. Another reason the African Penguin population was decreasing is Guano on the islands on which the penguins breed. It became the basis for a new industry and workers removed thousands of pounds. .....

.... phenomena from spiritism and to investigate mediums and their activities." (http://wheel.ucdavis.edu) The research started over one hundred years ago and their goal was to understand why unexplainable phenomena was occurring. "Modern experiments, notably at Duke University under Joseph Banks Rhine, in Britain at the Society for Psychical Research and in Russian research labs, have concentrated principally on extrasensory perception, psychokinesis, and astral projection." (http://wheel.ucdavis.edu) J.B. Rhine did experiments in the field of extra sensory perception to test if it actually existed. Rhine made the "ESP cards" fam .....
