... extinction theory. It says that a climate change via the greenhouse effect killed off the dinosaurs. My paper takes this proposed theory and relates it to the world today. Some of the things that happened back then are also happening now, and if the dinosaur- greenhouse extinction theory is indeed true, then we are also in danger of dying from the greenhouse vertebrate killing mechanism, abrupt atmospheric changes, and the other effects caused by the increased greenhouse effect and people should know about the consequences of what we are doing to the earth. My paper examines the similarities occurring in the two time periods and the possible results tha ...
... the symptoms are rather mild and increase in severity at a gradual rate over a period of years. Excessive Daytime Sleepiness (EDS) and Cataplexy are the two primary symptoms of . Other symptoms include Disrupted Nighttime Sleep, Sleep Paralysis, Hypnagogic Hallucinations, and Automatic Behavior . However, only 20 to 25 percent of patients suffer the complete range of symptoms. EDS is usually the first symptom to be noted. It is sometimes expressed as sleepiness, tiredness, lack of energy, sleep attacks, or an unusual susceptibility to becoming sleepy or falling asleep. In general, the development of EDS is a slow process and requires several years to become an ob ...
... and 8 molars- begin to develop pior to birth. They are eventually replaced- beginning around the age of 6 -by 32 permanent teeth.: 4 central incisors, 4 lateral incisors, 4 cuspids, 8 bicuspids (premolars), and 12 molars. The 4 wisdom teeth develop after the other 8 molars, as the jaws increase in size. If this increase is insufficient, the wisdom teeth may become impacted, that is wedged between the jawbone and other teeth, sometimes resulting in pain and inflammation. The upper teeth, called maxillary, and the lower teeth, called mandibular, are shaped in such a manner that they interdigitate (fit together) when the jaws are closed. This fit is essential for th ...
... main effects and side effects, of the drug, patients taking it would receive no "high", no positive reinforcement, and would gradually be able to become successful in a treatment program. The problem with this point of view is that cocaine has not been shown to be very physically addicting, as there are no major symptoms of withdrawal that the patient is trying to combat by self-administering more of the drug. By making the drug ineffective in the blood stream, addicts would not receive what is thought to be positive reinforcement through cocaine's effects on the dopaminergic systems in the brain, but there is no evidence to prove that it would therefore stop th ...
... and, in essence, is logical analytical, judgemental and verbal. It's interested in the bottom line, in being efficent. The right brain controls the left side of the body and leans more to the creative, the intuitive. It is concerned more with the visual and emotional side of life. Most people, if they thought about it, would identify more with their left brain. In fact, many of us think we are our left brains. All of that non- stop verbalization that goes on in our heads is the dominant left brain talking to itself. Our culture- particularly our school system with its emphasis on the three Rs (decidedly left-brain territory) - effectively represses th ...
... certain drugs causes dependence and the use of the drug becomes a habit that is hard to break. Drug dependence is both psychological and physical. Psychological dependence involves a craving for the psychological experience a drug provides. Physical dependence means that the user builds a tolerance to the drug. When this happens the user needs more and more of the drug to achieve the same effect. If a person develops this type of tolerance and then stops using the drug he/she will suffer from drug withdrawal. The body then needs the drug so badly that the user will seek even more of the drug even though it is harmful. This condition is called addiction. Dr ...
... This is such as self abortion methods wich are even more dangerous; these included are lye, lysol, iodine douches, as well as self inserted catheters, knitting needles and goose quills. When women lose their right to choose abortion they may start performing them illegally. This may do serious harm to the mother and her body. Aborton is a woman's choice. Woman accepted the definition that a womans prime role was as wife and mother and control of ones own body. Once they had choices about life roles, they came to feel they had the right to choose abortion to run their own lifes. Any woman should have the ability to choose when to have a child in their mar ...
... breast cancer, particularly in China and Japan. The fourth on the list is colon or rectum cancer, a disease that mainly strikes the elderly. In the United States in the mid-1980s, more than one-fifth of all deaths were caused by cancer; only the cardiovascular diseases accounted for a higher percentage. In 1990 the American Cancer Society predicted that about 30 percent of Americans will eventually develop some form of the disease. In the United States skin cancer is the most prevalent cancer in both men and women. Lung cancer, however, causes the most deaths in both men and women. LEUKEMIA, or cancer of the blood, is the most common type seen in children. ...
... anorexia more often starts during adolescence. The incidence of anorexia or bulimia in males is about 5% of all cases, with the onset of the disorders generally mid-teens to early twenties. 2. What are the causes of the eating disorders Anorexia Nervosa and Bulimia? There are many theories, but no clear picture. It is an over simplification to blame the mass media's presentation to blame the mass media's presentation of the ideal shape: though western society's increased emphasis on the slim, fit body places pressure on many people. We know there are many factors affecting the development of the disorders- biological, psychological and sociological- so ...
... has a high frequency of metastasis yet generally remains localized within the peritoneal cavity. Tumor development has been associated with aberrant, dysfunctional expression and/or mutation of various genes. This can include oncogene overexpression, amplification or mutation, aberrant tumor suppressor expression or mutation. Also, subversion of host antitumor immune responses may play a role in the pathogenesis of cancer (Sharp, 77). Ovarian clear cell adenocarcinoma was first described by Peham in 1899 as "hypernephroma of the ovary" because of its resemblance to renal cell carcinoma. By 1939, Schiller noted a histologic similarity to mesonephric tu ...
