  • Aids - 1,103 words
    Aids Aids Acquired Immune Deficiency Syndrome (AIDS), suppresses the immune system related to infection with the human immunodeficiency virus (HIV). A person infected with HIV gradually loses immune function along with certain immune cells called CD4 T-lymphocytes or CD4 T-cells, causing the infected person to become vulnerable to pneumonia, fungus infections, and other common ailments. With the loss of immune function, a clinical syndrome (a group of various illnesses that together characterize a disease) develops over time and eventually results in death due to opportunistic infections (infections by organisms that do not normally cause disease except in people whose immune systems have be ...

  • Aids - 1,410 words
    Aids Aids by sean ross How is HIV Diagnosed? You can get tested for HIV in a number of locations -- including public clinics, AIDS organizations, physicians' offices, and hospitals. Many locations give the test for free. You can choose between anonymous tests, in which you do not give your name to the HealthCare provider, or confidential tests, in which you do give your name. Test sites should provide trained counselors who can offer you support and guidance, no matter what the test result.(Balch-97) An HIV test looks for the antibodies your immune system creates in response to the virus. These antibodies may not appear in your blood until three to six months after HIV infection. Therefore, ...

  • Air Pollution - 1,493 words
    ... ures have in fact been rising, and the years from 1987 to 1997 were the warmest ten years on record. Most scientists are reluctant to say that global warming has actually begun because climate naturally varies from year to year and decade to decade, and it takes many years of records to be sure of a fundamental change. There is little disagreement, though, that global warming is on its way. Global warming will have different effects in different regions. A warmed world is expected to have more extreme weather, with more rain during wet periods, longer droughts, and more powerful storms. Although the effects of future climate change are unknown, some predict that exaggerated weather condi ...

  • Alcohol Abuse - 1,364 words
    ... get a BAC that high? A 160 pound man will have a BAC of about .04, 1 hour after consuming two 12-ounce beers on an empty stomach. Your BAC will depend on how much you weigh, how much you drink, amount of time since your last drink and your gender. Women metabolize alcohol differently from men, causing women to reach higher BAC's at the same doses. Recent research is showing that true substance dependence may be caused, in part, by brain chemistry deficiences. That is one reason that substance dependence is considered a disease. And, as with other diseases, there is the possibility of taking medicine to get better. There is now promising evidence that taking medicine can correct some of ...

  • Aluminum - 1,420 words
    Aluminum Aluminum is one of a number of soft metals that scientists call poor metals. It can be shaped and twisted into any form. It can be rolled into thick plates for armored tanks or into thin foil for chewing gum wrappers. It may be drawn into a wire or made into cans. Aluminum is a generally popular metal because it does not rust and it resists wear from weather and chemicals. (Bowman, 391) Aluminum is an element. Its atomic number is thirteen and its atomic weight is usually twenty-seven. Pure aluminum melts at 660.2C and boils at 2500C. Its density is 2.7 grams per cube centimeter. Aluminum is never found uncombined in nature. (Bowman, 391) Aluminum is a very useful metal that is ligh ...

  • Art Of Living By Thoreau Walden - 1,858 words
    Art Of Living By Thoreau Walden Thoreaus Art of Living In Thoreaus Walden, he explores the art of living by presenting a dichotomy of sojourning in nature. The life of participating with nature considers living simply and wisely while cooperating with both its lowest and highest elements. Thoreau calls for a change in life by changing the conventional ideas of standard societal views and its participation with the torpor of the material mass. Throughout Walden, Thoreau delves into his surroundings, the very specifics of nature while trying to live the ideal life. Perhaps the main theme and overbearing concept that Thoreau wishes to convey to the reader both in the conclusion and throughout W ...

  • Blood Is A Fluid Substance That Circulates In The Arteries And Veins Of The Body Blood Is Bright Red Or Scarlet When It Has B - 1,393 words
    Blood is a fluid substance that circulates in the arteries and veins of the body. Blood is bright red or scarlet when it has been oxygenated in the lungs and passes into the arteries; it becomes bluish red when it has given up its oxygen to nourish the tissues of the body and is returning to the lungs through the veins and the tiny vessels called capillaries. In the lungs, the blood gives up the carbon dioxide wastes it has taken from the tissues, receives a new supply of oxygen, and begins a new cycle. This movement of blood is brought about by the coordinate activity of the heart, lungs, and blood vessels. Blood is composed of a yellowish fluid, called plasma, in which are suspended the mi ...

  • Bouyancy And Displacement - 709 words
    Bouyancy And Displacement Buoyancy and Displacement Ships do not sink because of displacement; the ship moves more water than the ship actually weighs. Archimedes Principle: Any object wholly or partly immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. Density is mass of a unit volume of a material substance, expressed as kilograms per cubic meter in MKS or SI units. Density offers a convenient means of obtaining the mass of a body from its volume or vice versa; the mass is equal to the volume multiplied by the density, while the volume is equal to the mass divided by the density. The weight of a body, which is usually of more practical inte ...

  • Brave New World - 713 words
    Brave New World Brave New World George Santayana once said, "Ideal society is a drama enacted exclusively in the imagination." In life, there is no such thing as a "complete utopia", although that is what many people try to achieve. Aldous Huxley's Brave New World is an attempt at a utopian society. In this brave new world, mothers and fathers and family are non-existent. Besides being non-existent, when words of that sort are mentioned, ears are covered and faces of disgust are made. In a report to the Controller, Bernard wrote," ... This is partly due, no doubt to the fact that he heard them talked about by the woman Linda, his m-----"(106). Words of the sort cannot even be written. Art, h ...

  • Brave New World And 1984 - 1,356 words
    Brave New World And 1984 Imagine a world in which people are produced in factories, a world lost of all freedom and individuality, a world where people are exiled or "disappear" for breaking the mold. Both 1984 by George Orwell and Aldous Huxleys Brave New World are startling depictions of such a society. Although these novels are of fictional worlds, control of the future may be subtly evolving and becoming far worse than Huxley or Orwell could ever have imagined. Each society destroys the freedom of the individual through various controlling methods such as the denial of language and literature, a caste system and conditioning. One way in which each society controls is by limiting the lang ...

  • Brazilian Economy - 1,055 words
    Brazilian Economy An Economy Recovering From Chaos. Brazil earned the reputation of being a "miracle economy" in the late 1960s when double-digit annual growth rates were recorded and the structure of the economy underwent rapid change. Since 1981, however, Brazils economic performance has been poor in comparison to its potential. The countrys dramatic reduction in output growth, which averaged an annual GDP growth of only 1.5 percent over 1980-93, reflected its inability to respond to the events of the late 1970s and 1980s. Some events that took place during this period were: the oil shock, increases in real interest rates, the debt crisis, and the resulting cutoff of foreign credit and for ...

  • Brisbane River - 1,955 words
    Brisbane River 1.0 INTRODUCTION The Brisbane River has flowed for over 400 million years. The catchment of the Brisbane River has overcome phases of flood and drought while its origins altered as the surrounding land changed overtime. In 1823, John Oxley entered the river for the first time. At the time the river appeared clean and unpolluted. Oxley immediately recognised the river's potential as a site for new settlement, through his recommendation the city of Brisbane was established in 1825. The Brisbane River extends inland for 300km reaching its source at the foothills of the Great Dividing Range.

Bake for 40 to 45 minutes and voile! Could it be just as easy to make a universe? Since the big bang theory implies that the entire observed universe can evolve from a tiny speck, it's tempting to ask whether a universe can in principle be created in a laboratory. Given what we know of the laws of physics, would it be possible for an extraordinarily advanced civilization to crea ...

While a black hole is interesting, it would certainly be viewed as a disappointment by our would-be universe creator. Suppose, however, that the bubble was not started from rest, but instead was given an outward push. If the initial outward velocity is large enough, then the bubble will follow the sequence shown in the figure on the facing page. As the bubble grows, the indentation will become deeper, as shown at the top. The indentation will continue to deepen, developing a neck, or wormhole, as shown in ...

  • Crystals - 1,487 words
    Crystals Crystals What is a crystal? A crystal is a solid substance with definite geometric shapes and molecules that are arranged in a repeating pattern (Comptons ). Crystals have fixed angles between its faces, which have distinct edges. If the faces of a crystal can reflect light, then it will sparkle (Stangle). Crystals have constant angles because of the regular arrangement of its particles. There are seven types of crystals: cubic, tetragonal, orthorhombic, hexagonal, trigonal, monoclinic, and triclinic (Dr. Boyle). Crystals are classified by the shapes of their lattice or the regular, periodic configuration of particles (American Heritage). There are two different types of lattices. T ...
