... the researchers who are trying to create very real applications for medical, space, physical, chemical, and entertainment uses among other things. In order to create this alternate reality, however, you need to find ways to create the illusion of reality with a piece of machinery known as the computer. This is done with several computer-user interfaces used to simulate the senses. Among these, are stereoscopic glasses to make the simulated world look real, a 3D auditory display to give depth to sound, sensor lined gloves to simulate tactile feedback, and head-trackers to follow the orientation of the head. Since the technology is fairly young, these interfaces ...
... atomic spectroscopy provides a technique that can quantify metal concentrations in the extracts of the soil samples and consequently examine the relationship between distance from the point of road salt application and akali metal concentrations. Experimental Soil preparation: Six surface soil samples were collected at the intersection of Cold Spring Lane and the exit ramp of Interstate 83, in northwest Baltimore city. These samples were collected at distances from the roadway of 0m, 2m, 4m, 6m, 10m, and 20m. These samples were dried in a convection oven at 110°C for over 24 hours then crushed. Aliquots of approximately one gram were weighed and then extracted ...
... the GAS model. (Author, pg#). Dr. Selye preformed most of the early work on the adaptation syndrome. His experiments in general looked at harmful stimuli on the response of the body. In an experiment, Seyle exposed a large number of rats to a refrigerated room where the temperature was near freezing,(Author pg#) “…during the first 48 hours they developed the typical manifestations of the alarm reaction. This was proved by killing ten animals at the end of the second day; all of them had large fat-free adrenals, small thymuses, and stomach ulcers.” (Seyle, 1956; 88). This experiment conducted illustrated the vast number of physical changes the body und ...
... soon a new rivalry emerged between the creationists and evolutionists. According to Charles Darwin man began as one of a few species on this new planet striving for survival. However, man was better equipped with certain traits that allowed him to pass through the filter of natural selection. Man was supplied with both physical and intellectual traits that were responsible for allowing him to surmount the other species living beside him. He was able to use his physical traits in order to become the greatest predator, and severely diminish the possibility of become another species prey. His physical traits were also very adaptable and so man was able to change w ...
... 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 don't think it's ...
... on, undetected at the source, in an ever-expanding circle of bad data. And some systems will stop working altogether. How might systems fail? Let's look at an example program in which the omitted century is assumed to be '19' and the program's function is to figure out how old you are. If you were born in 1958, then in 1999 this program will calculate your age as 99 minus 58, or 41. That's fine, but what happens when the century rolls over to '20' in the year 2000? In this program, the year will appear as '00' but the century will still be assumed to be '19' -- so the program will calculate your age as 00 minus 58, or -58. Then, depending on the program's error-hand ...
... earth. Greenhouse gases include water vapour, carbon dioxide (CO2), methane (CH4), chloroflurocarbons (CFCs), Ozone (O3), and Nitrous Oxide (N2O). It all seems very straightforward: greenhouse gases trap the sun's heat, warming the planet sufficiently for life to exist. There is, however, one problem: human activity has dramatically increased the amount of greenhouse gases in the atmosphere. Over the last two centuries the concentration of greenhouse gases in the atmosphere has increased quite significantly, mainly as a result of burning fossil fuels for industrial purposes. For example, atmospheric concentrations of carbon dioxide have increased from 280-285 part ...
... Deforestation is the large-scale removal of forests. Why does deforestation occur? There are a many answers to that question but the main ones are: Ø For agricultural purposes eg space for building. (overpopulation) Trees are logged for the purpose of space. In this day and age the human race is multiplying and therefore we require more space to expand cites and build more houses. To do this world government cut down any forests in their way. Ø Industrial commercial purposes Big industries also contribute to deforestation. EG "Macdonald's uses 800 square miles of trees just for the paper packaging of their products". That is an appalling amount of ...
... ideas, they came across Mendel's results" (14). Their data agreed, and with this a new science was born - the science of Genetics (15). Due to modern medicine, such as antibiotics and rehabilitation, many genetic diseases have been allowed to survive. In nature, these diseases would not have survived to the extent that they do now. Advances in science and medicine have allowed these problems to thrive. Further advances in science may be able to terminate genetic diseases through cloning. Genetic problems have plagued the United States for centuries. Genetic diseases and mutations are more prevalent in today's world than ever before, due to advances in medic ...
... month gestation period. Newborn fawns will weigh about four pounds at birth. Deer offspring are cared for and may remain with the mother until the next spring. Fawns retain their spots until mid September and nurse until mid October. About 40 percent of female fawns breed during their first autumn, but usually bear only one fawn. Does breeding at age 1 1/2 or older generally have twins, and sometimes triplets. By November, Kentucky's deer population typical increases slightly more than one fawn per doe. Although many more fawns are born than one per doe, some will die before the hunting season arrives. A deer's home range averages about 500 acres. In moun ...
