... pneumonia. The annual cost of is estimated to exceed $2 billion. Most s are silent, causing no symptoms. However, men and women with Chlamydia may experience abnormal genital discharge or pain during urination. These early symptoms may be mild. If symptoms occur, they usually appear within one or three weeks after exposure. Two of every three infected women and one or two of every four infected men have no symptoms whatsoever. As a result, often the disease may not be diagnosed and treated until complications develop. Doctors estimate that, in women, one third of the s result in PID (Pelvic Inflammatory Disease). ...

... human settlement. We ask ourselves, did the help or hinder settlement in the Western United States? As settlers began to move westward, the Southwest was considered to be a place to avoid. Few considered it a place to traverse, to spread Christianity, and a possible source of furs or mineral wealth. Finding a reliable or accessible water source, and timber for building was difficult to find. There was a lack of land that could be irrigated easily. By the turn of the century, most present day cities and towns were already established. Trails, roads, and railroads linked several areas with neighboring regions. Altho ...

When treated early, there are no long-term consequences of . Serious complications can result, however, when left untreated. Long term complications in men may include Epididymitis. Long term complications in women include Pelvic Inflammatory Disease, ectopic pregnancy, perihepatitis, sterility can be transmitted to newborns. Approximately 2% of persons with untreated may develop Dis ...

... Language, Third Edition, 1992). The nuclei of isotopes of the same element have the same number of protons but they have different numbers of neutrons (The America Heritage Dictionary of the English Language, Third Edition, 1992). The isotopes of a given element have identical chemical properties but varying physical properties (The America Heritage Dictionary of the English Language, Third Edition, 1992). A radioisotope is a radioactive isotope (The America Heritage Dictionary of the English Language, Third Edition, 1992). A radioisotope is a naturally or artificially created isotope having an unstable nucleus ...

... but they were not as accurate as the ones produced around 1900. In the later twentieth century people developed a increasing "need" for pure gold and silver. European and American scientists developed a new advanced way for this- amalgams. Amalgams are alloys of mercury usually used to extract elements from there various ores. Then, once the common metal is extracted mercury is then separated through distillation. Without mercury our world would be much different. We would have different, if any, ways of determining temperature. Mercury is also used in cleaning modern day swimming pools as "Mercury V ...

... filter. With the invention of the electron microscope by Ernst Ruska, the virus' true anatomy was first time visible to us in 1933.2 They are so infinitesimal that billions could fit into a drop of water---or a drop of human blood. Viruses have the most exquisite ability to sense the right cell surfaces. They don't just cause diseases in people, they infect every form of life on earth. Some emerging viruses are very serious. Common examples are the viruses, B and C. The B pattern of illness was recognized at the end of the nineteenth century, yet the virus itself was not isolated until 1963. One hund ...

... in rock which is exposed to air and water. The major components of ARD formation are reactive sulfide minerals, oxygen, and water. Biological activity and reactions is what is responsible for the production of ARD. These reactions make low pH water that has the ability to mobilize heavy metals contained in geological materials with which it comes in contact. "ARD causes a devastating impact on the quality of the ground or surface water it discharges to. (Ellison & Hutchison)" ACID MINE DRAINAGE Within the mining process there are several sources that cause ARD. No matter what activities occur, ARD ...

... is the reason the Human Genome Project has been started. Scientist around the world are using super computers to crack the code. This 15 year project is predicted to end by the year 2005(Dewitt, 1994). That is only 10 years from now. What does that mean to the average Joe? Well, today we already live with genetically engineered items. The FDA has approved bioengineered tomatoes that ripen without rotting(Dewitt, 1994). Entire herds of cattle are now being injected with a growth hormone(BST) so that they will produce more milk than ordinary cattle(Dewitt, 1994). Also drought resistance grass that needs no moving ...

... a wheelchair. This affliction prevents Hawking from reading, writing, or calculating in a direct and simple way. The bulk of his work, involving studying, publishing, lecturing, and worldwide travel, is carried on with the help of colleagues, friends, and his wife. Of his illness, Hawking has said that it has enhanced his career by giving him the freedom to think about physics and the Universe. Stephen Hawking has written many essays involving the unified theory, which is a theory summarizing the entire of the physical world; a theory that would stand as a complete, consistent theory of the physical interactions t ...

... even more confused, but both sides have a good case. For example an unwanted child is a pitiful thing, and the apparent social problems like child neglect, and financial burden that comes with it don’t have easy solutions. On the other hand, the thought of killing a little baby is disgusting and unthinkable. This is where I stand, and the only solution I can come up with is the total ban of altogether. This task should not be a hard one, but it might take some time. My plan calls for the closing and the illegalizing of abortion clinics, and the prosecution of people who perform these deeds. As with an ...
