Long Term Affects Of Fas

... a child being born to Fetal Alcohol Syndrome, otherwise known as FAS. One in thirty births are born with Fetal Alcohol Effects. Those diagnosed with FAS have prenatal and postnatal birth deficits, central nervous system dysfunction, specific facial characteristics, and body malformation problems. Children who display only some of these effects are claimed to have FAE, or fetal alcohol effects. The sad thing is that most infants and children who suffer from fetal alcohol effects go unnoticed. They are looked upon as having behavioral proble ...

Essay On Global Warming

... the Earth’s surface and warms it even more. Some of the naturally occurring greenhouse gases are Methane and carbon dioxide. This is the way the Earth keeps itself warm enough for humans to live on it. The only problem with this is that humans enhance the process even more. Over the past 200 years the emissions of greenhouse gases have been increasing due to the increase in technology that humans have developed (example, factories). These human-induced gases include carbon dioxide, methane, nitrous oxide, and ozone depleting substance ...

Bovine Spongiform Encephalopathy

... that BSE is a neurological disease, it is characterized by many distinct symptoms: changes in mental state 'mad-cow', abnormalities of posture, movement, and sensation (Hunter, 1993). The duration of the clinical disease varies with each case, but most commonly lasts for several weeks. BSE continues to progress and is usually considered fatal (Blowey, 1991). After extensive research, the pathology of BSE was finally determined. Microscopic lesions in the central nervous system that consist of a bilaterally symmetrical, non-inflammatory vacu ...

Cyclohexanone

... range 2.5 to 15 micrometers which correspond to approximately 4000 to 600cm-1”(Young). “When atoms or molecules absorb light, the incoming energy excites a quantized structure to a higher energy level. The type of excitation depends on the wavelength of the light. Electrons are promoted to higher orbirtals by ultraviolet or visible light, vibrations are excited by infrared light, and rotations are excited by microwaves” (Tissue). IR spectroscopy is the measurement of the wavelength and intensity ...

Comets

... all the mass of the comet, is a “dirty snowball” conglomerate of ices and dust. Major proofs of the snowball theory rest on various data. For one, of the observed gases and meteoric particles that are ejected to provide the coma and tails of comets, most of the gases are fragmentary molecules, or radicals, of the most common elements in space: hydrogen, carbon, nitrogen, and oxygen. The radicals, for example, of CH, NH, and OH may be broken away from the stable molecules CH4 (methane), NH3 (ammonia), and H2O (water), which may exis ...

Ozone

... unstable, and solutions containing ozone explode upon warming. It is found in varying proportions on Earth, but it is about 0.05 ppm at sea level. Ozone absorbs harmful ultraviolet radiation in the upper atmosphere, and protects humans from skin cancer. But ozone is also the main ingredient of smog, and causes serious health effects and forest and crop damage in the lower atmosphere. Ozone is formed through the chemical reaction of volatile organic compounds and nitrogen dioxide, in the atmosphere, in the presence of sunlight. This reacti ...

The Overpopulation Of The Snow Goose In North America

... same time most troublesome. Ross’ Goose (ROGO) is very similar to the Lesser and can only be distinguished by close observation. Both the Lesser and the Ross nest in salt marshes along Hudson Bay and then migrate down to the gulf coast states such as Texas and Louisiana. Their populations number in the millions. The third sub species is the Greater Snow Goose. They nest in the same marshes as the others except they migrate down the Atlantic Coast into the Carolinas and that vicinity. All three species have exploded in numbers since ...

The Element Cesium

... compounds were very expensive until lithium by- products were found to have trace amounts of isolatable Cesium compounds. Once the knowledge of Cesium compounds was discovered, the study of it’s chemical properties was initiated. Perhaps the most dynamic chemical reaction of Cesium occurs when it is exposed to oxygen. This exposure causes oxides to form, where even the heat from oxidation is enough to melt and ignite this metal. Another major reaction of Cesium occurs with water and ice. Ice with a temperature as low as -177 degrees Fahren ...

Ebola 3

... as filoviruses. Filoviruses are enveloped, single stranded, negative-sense of RNA viruses. Ebola is the deadliest virus known to man, and spreads in a breath of air. The symptoms of this deadly virus starts with sudden fevers, weakness, muscle pain, extreme headaches, and soar throats. These symptoms begin four-sixteen days after infection. After about 2 days of these symptoms you start to "crash". A crash is when you vomit uncontrollably until there is nothing left to vomit (you vomit blood, bile and other liquids of the body), you suffer fr ...

Mechanical Energy

... without the fuel that the aircraft gets within its wings or fuselage. Fuel is considered a chemical energy. This diagram shows how the jet engine acts as energy to lift the aircraft off the surface of earth. Fuel can take the form of gases, solids or liquids. When fuels combine with oxygen from the air, they release their stored energy as heat. We recognize this process as burning. The individual relies on food for fuel which contains energy-giving substances that our bodies can store until we need this energy to use our muscles. When we ...

Biological Effects Of Radiation

... interactions with the atoms forming the cells. Even though all subsequent biological effects can be traced back to the interaction of radiation with atoms, there are two mechanisms by which radiation ultimately affects cells. These two mechanisms are commonly called direct and indirect effects. If radiation interacts with the atoms of the DNA molecule, or some other cellular component critical to the survival of the cell, it is referred to as a direct effect. Such interaction may affect the ability of the cell to reproduce and, thus, survi ...

Effects Of Smoking

... even in some severe cases has been proven too cause impotency in men. But out of all of these, the worst side effect of smoking is cancer; it is a life threatening disease that can affect many parts of your body at once. Lung cancer is one of the most common type of cancer caused by smoking. Smoking can cause cancer in the stomach as well in the throat. Smoking not only attacks your health, but it can also attack your pocketbook. The costs of a single pack of cigarettes has raised substantially in recent years, from 1.75 in the late '80s ...
