.... grave robbing, rather than a way to recreate and understand the ways of past societies. While the artifacts uncovered can be helpful in painting a picture of what the lives of past civilizations were like, the act of digging up such artifacts can be considered immoral. A person claiming to be conducting an archeological study in a present-day cemetery would most definitely be apprehended and punished for his actions. Cemeteries are considered sacred places, and those who violate the laws made to protect them will be punished for their actions. There is no difference between the aforementioned act and that of unearthing sacred Native American burial grounds, for ex ....

.... Even though people are trying to help this problem time can’t be turned back and much damaged has already occur. Air Pollution Factories and transportation (like cars or planes) depend on huge amounts of fuel every year. When these fuels burn they introduce smoke and other, less visible, by-products into the atmosphere. Although wind and rain occasionally wash away the smoke given off by power plants and cars, the cumulative effect of air pollution poses a grave threat to humans and the environment. In many places smoke from factories and cars combines with naturally occurring fog to form smog. Smog has been long recognized as a potential cause of death, especially for e ....

.... travel. It also allows employees to meet "face-to-face" over a desktop PC and share and review documents with colleagues, clients or vendors. You can hold a Desktop Videoconference whenever the need arises, without the time and expense of traveling-or even leaving your desk because it's just like being there in person. in no way takes the place of face to face, but it does offer the convenience of a different means of communication. Videoconferencing is a type of conferencing in which video cameras and microphones capture sight and sound for transmission over a communications network. Videoconferencing makes it possible to conduct meetings with participation of ....

.... survival, growth, and reproduction in areas supplied with freshly cut white spruce (Picea glauca) and aspen (Populus tremuloides). Similar trends were obtained in all three areas: population size, survivorship, reproduction and growth. Between critical winters of 1981-1982 the experimental grid area lost 77% of its population as compared to 79% and 96% loss for the control grids. Determining the survival rates, the authors used mark-recapture techniques, it was found that probabilities for survivorship in experimental grid (0.79+0.10) were similar to that of control grids (0.71+0.07; 0.56+0.07). Results yielded that extra food intake and cover provided from branches may ha ....

.... as children. Perhaps it is because we live in a nation filled with many peoples of different beliefs whose Gods are all so varied and different that it is difficult to fathom that they are all the same divine being. It is also plausible that we just have a desire to quench the thirst for knowledge that lies deep within ourselves. As for myself, I cannot believe in a being which created a universe and a multitude of worlds in a rather short period of time then deigns to lower itself into becoming a puppet-master and "pulling the strings" of the Earth and all of the people therein. Since this paper touches upon many scientific terms, I feel that in order for the reader to c ....

.... and their effects on the form, or phenotype, of organisms that make up that population or species. Another way to state the difference is that macroevolution is between-species evolution of genes and microevolution is within-species evolution of genes. There are various kinds of dynamics of macroevolution. Punctuated equilibrium theory proposes that once species have originated, and adapted to the new ecological niches in which they find themselves, they tend to stay pretty much as they are for the rest of their existence. Phyletic gradualism suggests that species continue to adapt to new challenges over the course of their history. Species selection and species sorting t ....

.... and abnormalities in newborns. Evidence provided to support these claims of human and wildlife harm is largely from laboratory studies in which large doses are fed to test animals, usually rats or mice, and field studies of wildlife species that have been exposed to the chemicals mentioned above. In laboratory studies, high doses are required to give weak hormone activity. These doses are not likely to be encountered in the environment. However the process of bioaccumulation can result in top-level predators such as humans to have contaminants at levels many million times greater than the environmental background levels (Guilette 1994). In field studies, toxicity caused ....

.... first work on ESP was done by the Society for Physical Research in London founded a century ago. Scientists have run thousands of experiments to learn if minds indeed have supernatural powers. Most tests investigated one of the three main "faculties": telepathy, clairvoyance and precognition, collectively called extrasensory perseption (ESP) by American psycologist J.B. Rhine. Dating from the early 1930s, Rhine's tests at Duke University at Durham, North Carolina, remain the most quoted examples of an expirimental blitzkreig on problems of parapsychology. Three years of Rhine's telepathy and clairvoyance testing averaged 7 successes out of every 25 people tested, 2 bet ....
