- 14991: Infectious Diseases
- ... of cases increases on a yearly basis. This is why individuals should take further precautions in preventing these diseases as well as preventing the spread of them on a global scale. Many people in today's society must take a more serious look at the implications that an infectious disease can have on one's life. What are STDS? Sexually transmitted diseases (STDS), also known as venereal diseases, is a broad term that refers to more than fifty diseases and syndromes, which may be transmitted through the exchange of body ... a germ or a virus and are able to spread in any number of ways. Though most are spread through the act of sexual contact such as intercourse, oral sex and by touching your partner's genitals, they may also be acquired through airborn particles as well as general contact from hugging or brushing up with other individuals. Most infectious diseases attack the body through the bloodstream, slowly breaking down ...
- 14992: Hypnotism Is It Magic Or Reality
- ... deepest sleep possible (Goldberg 13-14). Hypnosis takes place in the alpha level because the mind is still in a conscious state (Goldberg 14). During hypnosis dissociation occurs, which is when part of the mind s experience is separated from conscious awareness (Barber 2). This is why a hypnotized person is prone to believe suggestions made, no matter how absurd they are. "A deeply hypnotized person will swear that the sky ... shamans. People in ancient Egypt and Greece used it for healing and curing disease (Goldberg 10). One of the first known people to experiment with hypnosis was Father Gassner, a clergyman in the early 1770 s. In those days the belief was that if someone was ill, they were possessed by devils. To become well again, the devils would have to be cast out of the body. When a patient was ... during surgery in America. It was reported that even though a patient was "unconscious," the greater part of the brain was awake, and nerve impulses could still reach the brain (Bryan 12). Throughout the 1900 s hypnotism has taken great strides and has become better known to the public. Interest especially increased after World War I and World War II when doctors found out that it was useful for treating ...
- 14993: Greenhouse Gases And Consequences
- ... heat to get out. This makes for a much higher temperature inside the greenhouse. On a planetary scale, similar processes occur. Light from the sun has no trouble penetrating the atmosphere and reaching the earth's surface, warming it. The earth re-radiates much of this heat in the form of (invisible) infrared radiation. Infrared rays have a longer wavelength than visible light, and for this reason can be absorbed by ... of the heat back to the 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 ... the atmosphere, acting as a greenhouse gas. Released by burning of fossil fuels and plant materials, and by the use of nitrogenous fertilisers in agriculture. The increase in methane can be linked to the world's growing population and its need for food and disposable goods. The main sources are burning of vegetation, animal digestion, and breakdown of organic matter in landfills. Methane is also released from natural gas leakages, ...
- 14994: Global Warming Extended Definition Essay
- Global Warming Extended Definition Essay The importance of the stratospheric ozone layer, which filters out most of the sun's harmful ultraviolet radiation, in protecting the Earth's surface from the harmful effects of solar ultraviolet radiation has been recognized for many decades. It was not until the early 1970s, however, that scientists began to actually grasp the fact that even relatively small ... cause of this process has not been determined, yet scientists are aware of its reality and harm to humans. Many scientists believe global warming is caused by the increase of carbon dioxide in the Earth's atmosphere, while other scientists believe that the health threat caused by global warming is due to an unusual interaction between cosmic rays and clouds as well as other natural occurring events. The National Weather ...
- 14995: Genome Project
- Adam and Eve were doomed for trying to be like god, this is the same damnation mankind is headed to. Everyone s dream is to have absolute power and control of everything. The genome project and DNA engineering gives man the ability to create life and customize life to his specific needs of likes. So how good is too good? Man s ability to make life or create perfect human beings so they can be in a state of Utopia will disturb the balance of nature. Every individual, every child born on earth is unique in it s own way, not only by looks but also by their character, their DNA. Changing this by producing two of the same kind, of which one is produced in the laboratory, unbalances nature. A clone ...
- 14996: Endocrine Disruption
- ... possible modes of action, but why exactly are we concerned with them? Endocrine disrupting chemicals are especially dangerous due their ability to alter hormone function by both binding and non-binding to the receptor site/s. When the chemical agents bind to the receptor site/s they are able to effect growth, reproduction, development, behavior, among many other body functions. All the items listed in the preceding sentence are strongly related to hormone function. When the hormone molecules are functioning, as ... with other substances. An example of dioxins and furans reacting with other chemicals would be their reaction with polychlorinated biphenyls. Both dioxins and furans are fairly reactive to begin with, but adding heat and PCB s can produce some fairly nasty mixtures. The substances formed in these reactions are polychlorinated dibenzofurans (PCDF) and polychlorinated dibenzodioxins (PCDD) respectively. The PCDF s and PCDD s that were formed in the reactions have ...
- 14997: Describe The Main Limitations Suffered By Those With Chronic
- ... to the sufferers sensitivity to known triggers factors and the consequential effect on their daily functioning. The Global Strategy for Asthma Management and Prevention (1995) states that triggers are risk factors that cause asthma exacerbation’s by inducing inflammation or provoking bronchio-constriction. This report also describes the main triggers as allergens, air pollutants, respiratory infections, exercise and hyperventilation, weather changes, allergies to foods, additives and drugs, and emotional stress. For ... their careers”. Chronic asthma sufferers have to live with the need for treatment and with the limitations that having asthma places on their everyday lives. It is in this context that the asthmatics life area’s are most likely to be handicapped. In general, the chronic asthmatics activity choices are particularly handicapped. …. especially physical education. Exercise incites airflow limitation in most children and young adults who have asthma. Exercise appears to ... before being exposed to an identified trigger factor, can reduce the likelihood of an asthmatic reaction. The asthma management chart also describes what to do if following warning signs are observed : (1) the bronchodilator doesn’t bring expected relief, (2) a decrease in the peak expiratory flow, (3) Increased breathlessness and variation in peak flow rates during the day, (4) more frequent wheezing and a persistent dry cough and (4) ...
- 14998: Development Of Operating Systems
- ... handle and perform more complex tasks. The folowing report examines the development of operating systems, and how the changing tehcnology shaped the evolution of operating systems. First Generation Computers (1945-1955) In the mid-1940's enormous machines capable of performing numerical calculations were created. The machine consisted of vacuum tubes and plugboards, and programming was done purely in machine code. Programming languages were unheard of during the early part of the period, and each machine was specifically assembled to carry out a particular calculation. These early computers had no need for an operating system and were operated directly from the operator's console by a computer programmer, who had immediate knowledge of the computers design. By the early 1950's punched cards were introduced, allowing programs to be written and read directly from the card, instead of using plugboards. Second Generation Computers (1955-1965) In the mid-1950's, the transistor was introduced, creating ...
- 14999: Chicken Pox With Works Cited
- ... is the primary form which occurs when the person first contracts the disease. The virus remains in the body indefinitely, which can lead to the resurfacing of it again. This mostly happens when the body’s immune system is down and the virus can multiply again. This basically means that the herpesvirus is recurrent and can occur many times throughout a person’s lifetime. (7) The person with chickenpox is most contagious during the first couple of days before he or she breaks out in the rash. The rash is usually preceded by a few days of clod ... and scarring (6). If an infection does occur treat it with an antibiotic as quickly as possible to avoid complications (6). Never take aspirin for pain and/or fever because it may lead to Reye’s syndrome (6). Reye’s syndrome is (6) “a life-threatening neurological disorder.” (6) It is associated with the use of aspirin by children who have a viral infection (6). A person should consult a ...
- 15000: Avalanches
- ... about these life threatening snow masses. So in order to protect yourself from anything you must first learn how it works. First off there is three main components to an avalanche, without them you can’t have an avalanche. They go as follows: 1) snow 2) slope 3) snow instability. Secondly, there are two kinds of avalanches; slab and loose snow. Loose snow are minor and usually never exceed 20 miles per hour. While slab avalanches are the destructive and deadly mountain slides. It is not uncommon for one of these to destroy a small town or forest. Since loose snow avalanches aren’t very dangerous, I will discuss slab avalanches. The fundamentals of how these snow masses occur, what to look for when testing and just all-together prevention. The basic chemistry behind a slab avalanche is when ... break free from the lower layer. The formation of a slab is possible in many ways. One way is for the snow to develop a crust and then there be more snowfall. Since snow doesn’t bond to the crust it becomes a potential for an avalanche zone. Another way is for surface hoar to develop, or large ice crystal on the snow. This is usually caused by condensation on ...
