... subterranean caverns" (Matthys 87). However, with modern technology we found that what actually causes is tectonic plates which on average move only two inches per year they are driven by convection currents which is the upward movement of heated particles rising from the earth's molten core. As the plates are driven against each other one will try to and eventually will slip underneath the other. When plates move quickly an earthquake is the result. Before the availability of instruments capable of a quantitative measure of their magnitude, were classified according to their intensity. In 1931 a seismologist came up with twelve degrees of intensity rangin ...

... must grow. Wherever rainforests are found, sandy red coloured soil can be found as well. This soil contains few nutrients, which is why attempting to grow any sort of crops would be futile. On top of this soil is a thin layer of humus, which 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, ho ...

... openly publicized for the world to see. On the other hand, in the Soviet Union all space programs blended into a secretive military-industrial bureaucracy. Launches were not announced in advance, and only the successes were publicized. (Baker 158-161). During the early years of the Space Race, success was marked by headline-making, historical "firsts." Some of these firsts included the first satellite, the first robotic spacecraft to the Moon, the first man in space, the first woman in space, and the first spacewalk. To the chagrin of the United States, each of these early firsts were achieved by the Soviet Union, thus sparking the United States to not only catc ...

... most common type of arthritis, affecting over 16 million people in the United States today (1). Arthritis refers to inflammation or swelling of the joints. The most common form of arthritis is osteoarthritis, which is also known as degenerative joint disease because it is characterized by joint degeneration and loss of cartilage. Cartilage is the shock absorbing material between joints. The weight-bearing joints such as the knees, hips, and spine, as well as the hands, are the joints most often affected by osteoarthritis. These joints are under much greater stress because of additional weight and continuous use (lifting, sports, support, movement). The concern t ...

... the current tests are time consuming and technically difficult to do, are restricted to women over 35 and those who have a family history of chromosomal abnormalities. Prenatal tests using Willard's probes would be much simpler and faster to perform and could be available to all pregnant women who wish to take advantage of the technology. Current prenatal testing involves growing fetal cells in vitro and examining them, over one or two months, to see if there are two copies of a particular chromosome, which is normal, or one or three, which is abnormal. A test using Willard's probes would require only a few cells and a few days to detect abnormalities. "I do ...

... paid for by the U.S. Atomic Energy Commission. In this experiment 26 dogs died. One of the deaths occurred during an epileptic seizure; another from brain hemorrhage. Other dogs, before death, became feverish and anemic, lost their appetites, and had hemorrhages. The experimenters compared their results to those experiments conducted at the University of Utah and the Argonne National Laboratory in which beagles were injected with Strontium 90. They concluded that the dose needed to produce “early death” in fifty percent of the sample group differed from test to test because the dogs injected with Strontium 90 retain more of the radioactive substance than dogs force ...

... due to the increase in technology that humans have developed (example, factories). These human-induced gases include carbon dioxide, methane, nitrous oxide, and ozone depleting substances such as CFCs, also known as Chlorofluorocarbons, hydrofluorocarbons, and perfluorocarbons. These gases are generated a number of human activities such as fossil fuel combustion, waste disposal in landfills, the use of a refrigerator, numerous agricultural and industrial activities, and the cutting down of numerous forests. These human practices have already changed the chemical make up of the atmosphere. Between the pre-industrial times and today, we have seen the c ...

He says that, "As much as 80-90% of our doctors' offices are not compliant. 64% of hospitals still have serious problems with the Y2K issues," (Senate Y2K Report Wendy Griffith). The senate also believes that they will affect Medicare, power companies, banks, and stocks. People now believe that they must remove their money from the banks. This is true, but most of them are waiting until the end of the year to do this. If everyone goes to the bank simultaneously to remove their money, then they will cause an automatic depression. The banks do not have all of the money in the bank at the times that people will want the ...
