.... drafts to heights of 50,000 to 60,000 feet. The cumuli become towering thunderheads. From outside the storm area, air moves in over the sea surface to replace the air soaring upwards in the thunderheads. The air begins swirling around the storm center, for the same reason that the air swirls around a tornado center. As this air swirls in over the sea surface, it soaks up more and more water vapour. At the storm center, this new supply of water vapor gets pulled into the thunderhead updrafts, releasing still more energy as the water vapor condenses. This makes the updrafts rise faster, pulling in even larger amounts of air and water vapor from the s .....

.... it has been proven true a number of times, it has to be true. However, logically, it can never really be proven completely true, since it would take an infinite number of tests to do so. A pseudo-science is similar, in that it has laws. However, these laws are mostly restatements of known facts. For example, in astrology, they make claims about what you are like based on what day you were born. The things they say, however, are things that are statistically common for those people. They are also very vague, making the chances of being wrong increasingly low. Also, they can be interpreted in many different ways, allowing for unbelievable f .....

.... 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, survive. If enough atoms are affected in such a way that the chromosomes do not replicate properly, or there is a significant alteration in the information carried by the DNA molecule, then the cell may be destroyed by “direct� interference with its life-sustaining system. Indirect effects are caused by the reaction of radiation with the water that makes u .....

.... Thyroid gland strongly attracts iodine. Radioactive iodine is used both in diagnosing and in treating diseases of the thyroid. Nuclear power is changing the face of medicine with new cures and tests that will cure millions.. Nuclear power can be converted into strong and efficient nuclear energy and be used for many purposes. Nuclear power reactors generates heat that is converted into steam. The steam can be used directly for energy. This energy is used in transportation. Most military subs are now ran by nuclear energy. The most used purpose of nuclear energy can also be used to generate electric power for example in a commercial nuclear .....

.... now extinct doesn't give you aportrait of the process of extinction. The Javan tiger became extinct in the 1970's in a set aside special national park under full protection. Politicans and bureaucrats seem to be obsessed with numbers and not trends. Let me illustrate this with tigers. There are frequently requests as to the exact number of tigers, or a tiger subspecies left in the world. That tells you that there are people that care. But there are so little tigers left that we can not even keep track of them. We should look at the trend that the population is taking, rather than the number as a slice in time. Just as you might say of a young memb .....

.... ozone layer. This layer protects the inhabitants of earth by reflecting much of the suns harmful ultra violet (UV) rays. Without this layer above us, many living things including humans could not survive. The ozone layer is currently depleting and the reason for this is believed to be caused by a few things. Deforestation, fertilizer use and fuel combustion are minor contributors to this problem while chemicals such as chloroflourocarbons (CFCs), halons, carbon tetrachloride, methyl chloroform, methyl bromide and hydrochloroflourocarbons (HCFCs) are the major contributors to the deterioration of the ozone layer. These chemicals have industrial h .....

.... motion as it relates to light waves. Simple harmonic motion is the condition in which a particle that is moving along the x-axis has a displacement function given by the following relation x = Acos(wt + f) where x is the position along the x axis A is the amplitude or in other words the maximum possible displacement w is the angular frequency and f is the phase constant or phase angle and has units of radians per second. The phase constant determines the position of the particle at time t = 0. The quantity (wt+ f) is called the phase. The above function x repeats itself whenever wt = n2p where n is an integer. The period T of the motio .....

.... rainforest actually is. The two main types of rainforests are temperate and tropical. Tropical rainforests are located in Latin and South America, Africa, Southeast Asia, and other areas in which temperatures stay above 80 degrees Fahrenheit year round. They can be found in 85 countries all over the world, however, 90 percent of them are concentrated into fifteen countries, each containing over ten million hectares. Tropical rainforests receive 160 to 400 inches of rain each year. Although these dense, damp forests cover just 5 percent of the Earth's surface, they can provide homes for between 50 and 90 percent of the Earth's plants and animals ( .....

.... the subject have to do is to answer questions. Good quantitative research is determined by validity and reliability of the research method used (Teevan, 1995:161). Therefo re, the straight correlation study method used in the survey research of "Horatio Alger lives" lack components of validity and reliability. News Article Summary This article entitled "Horatio Alger lives" is basically a survey correlation study done on two distinct social classes; sons of wealthy fathers and sons of lower income fathers. The goal in this research was to determine which sons of the two distinct social groups mentioned, were to likely make more money in the futu .....

.... by binding adrenergic receptors in the hormone releasing cells of the pancreas. Epinephrine is called the “fight� or “flight� hormone. The actions of epinephrine and norepinephrine are generally similar, although they differ from each other in their effects. Norepinephrine constricts almost all blood vessels. Norepinephrine is formed by intravenous infusion to combat the fall in blood pressure associated with types of shock. Norepinephrine is formed in the body from the amino acid tyrosine, and epinephrine is formed from norepinephrine. Mineralocorticoids steroids control the overall body fluid. Mineralocorticoids are critical to regulate .....
