    Rocks And Minerals According to Websters Dictionary, the definition of a mineral is an inorganic substance. Citrine is one of the most popular minerals. It is a variety of quartz. Citrine is a yellowish-orange mineral. Citrine is a very popular gemstone because it is very affordable and very pretty. Along with topaz, citrine is the birthstone for the month of November and the anniversary gemstone for the 17th year of marriage (www.jewelrymall.com). Citrine is also considered a symbol of hope, youth, health, and fidelity (www.houseofonyx.com). In ancient times, citrine was carried as a protection against snake venom and evil thoughts (www.jewelers.net). Other names for citrine are Imperial To ...

  • 2001: A Space Odyssey - 1,255 words
    2001: A Space Odyssey The concept of space travel has been an interest to many since the beginning of time. Today, scientists are moving at a comfortable pace to expand our vast knowledge of the universe. Many authors dreamed of the possibilities while scientists tried to bring them to reality. The book "2001: A Space Odyssey," written by Arthur C. Clarke in the 1960's, proposed ideas about advanced space travel that took place in a time period only two years from now; however, at the current rate of the space program, mankind is nowhere near the technology showed by the book. Clarke uses concepts of space travel that can still only be dreamed of today. Clarke, an author of the sixties, had ...

  • Acid Precipitation - 663 words
    Acid Precipitation Acid Precipitation Our atmosphere functions as living ecosystem of chemical reactions. Through the help of the water cycle, chemicals pass through the atmosphere and are eventually taken up by the soil, surface water, or organic materials. Human beings have added enormously to the atmospheric burden of many toxic substances. The most prominent evidence of this is the presence of acid rain: precipitation and particles that have been made acidic by air pollution. Acid rain is a direct consequence of the atmosphere's self-cleansing process. The tiny droplets of water that make up clouds continuously capture suspended particles and soluble trace gases. Not all trace gases can ...

Osmoregulation is the process of maintaining the delicate balance of salts and minerals in their tissues. For freshwater fish, maintaining osmoregulation is key in their survival. Acid molecules, which are a result of acid rain in the water, cause mucus to form in the fishs gills. This in return prevents the fish from absorbing oxygen. If the fish are unable to absorb oxygen, the consequence could be the eventual suffocation of fish and the low pH could throw off the balance of salts in the fish tissu ...

  • Acid Rain - 1,289 words
    Acid Rain Pollution comes in various forms. Whether its toxic waste, CFCs, or sewage, they are all hazardous, to the earth. These can deplete the earth and its inhabitants of resources, causing a harmful change. A product of pollution is acid rain. We shall see that acidification is harmful to all forms of life. Acid rain is any form of precipitation that is polluted by sulphur dioxide (SO2), and nitrogen oxides (NOX). This acid precipitation can be in the form of rain, snow, sleet, fog, or cloud vapors. The acidity of substances dissolved in water are measured by their pH levels. Normal precipitation pH levels fall between 5.0-5.6.2 When levels fall below these numbers, then the precipitati ...

  • Acid Rain - 1,731 words
    Acid Rain Introduction: What Causes Acid Rain? One of the main causes of acid rain is sulfur dioxide. Natural sources, which emit this gas, are Volcanoes, sea spray, rotting vegetation and plankton. However, the burning of fossil fuels, such as Coal and oil, are largely to be blamed for approximately half of the emissions of this gas in the world. When sulfur dioxide reaches the atmosphere, it oxidizes to first form a sulfate ion. It then Becomes sulfuric acid as it joins with hydrogen atoms in the air and falls back down to earth. Oxidation occurs the most in clouds and especially in heavily polluted air where other compounds such as ammonia and ozone help to catalyze the reaction, changing ...

  • Acid Rains - 540 words
    Acid Rains Acid rain refers to all types of precipitation--rain, snow, sleet, hail, fog--that is acidic in nature. Acidic means that these forms of water have a pH lower than the 5.6 average of rainwater. Acid rain kills aquatic life, trees, crops and other vegetation, damages buildings and monuments, corrodes copper and lead piping, damages such man-made things as automobiles, reduces soil fertility and can cause toxic metals to leach into underground drinking water sources. Rain is naturally acidic because carbon dioxide, found normally in the earth's atmosphere, reacts with water to form carbonic acid. While "pure" rain's acidity is pH 5.6-5.7, actual pH readings vary from place to place ...

Says Mr. Waite, "The gold of the philosopher is not a metal, on the other hand, man is a being who possesses within himself the seeds of a perfection which he has never realized, and that he therefore corresponds to those metals which the Hermetic theory supposes to be capable of developing the latent possibilities in the subject man." At the same time, it must be admitted that the cryptic character of alchemical language was probably occasioned by a fear on the part of the alchemical mystic that he might lay himself open t ...

  • Alcoholism Is A Wideranging And Complex Disease That Heavily Plagues Society Drinking Is Defined As The Consumption Of A Liqu - 1,066 words
    Alcoholism is a wide-ranging and complex disease that heavily plagues society. Drinking is defined as the consumption of a liquid, and/or the act of drinking alcoholic beverages especially to excess. Every year alcohol is responsible for 1/2 of all murders, accidental deaths, and suicides; 1/3 of all drowning, boating, and aviation deaths; 1/2 of all crimes; and almost 1/2 of all fatal automobile accidents (Overview 1). Alcohol is a potent nonprescription drug sold to anyone over the national legal drinking age, 21. Unlike carbohydrates, fats, and proteins, which can be manufactured by the body, alcohol is a substance that is not made within the body. It is a food, because it supplies a conc ...

    ... d physiological processes are closely linked. The connection between stress and immune system response, for example, is well documented (Epiro and Walsh). Some scientists suggest that the power of prayer and faith healing, like some forms of meditation, might also be physiological in that they may protect the body from the negative effects of stress hormone norepinephrine. In addition, experience shows that relaxation techniques can help patients enormously. 'Medicine is a three-legged stool,' says Dr. Herbert Benson of Harvard Medical School (Epiro and Walsh). 'One leg is pharmaceuticals, the other is surgery, and the third is what people can do for themselves. Mind-body work is an esse ...

  • Ancient Egypt - 1,006 words
    Ancient Egypt The civilization of ancient Egypt is significant in several ways. Egyptian influence on other peoples was also significant. Ancient kingdoms of the Sudan adapted its HIEROGLYPHIC writing system and other cultural elements. The two last regions and the Bible are the most important antecedents of the modern western world that owe something to Egypt. The western alphabet is derived from a Phoenician one possibly modeled on Egyptian hieroglyphs; Egyptian ideas are found in some parts of the Bible; and Greek sciences and especially, art were originally influenced by Egypt. Finally, archaeology and historical writing have made Egypt a subject of great public interest, stimulating man ...

  • Aquaculture - 1,393 words
    Aquaculture Aquaculture is the farming of aquatic organisms in fresh, or salt water. A wide variety of aquatic organisms are produced through aquaculture, including fish, crustaceans, mollusks, algae, and aquatic plants. Unlike capture fisheries, aquaculture requires deliberate human intervention in the organisms' productivity and results in yields that exceed those from the natural environment alone. Stocking water with (juvenile organisms), fertilizing the water, feeding the organisms, and maintaining water quality are common examples of such intervention. Most aquacultural crops are destined for human consumption. However, aquaculture also produces bait fishes, ornamental or aquarium fish ...

  • Asteroids - 1,203 words
    Asteroids In our solar system today there are over 30 000 asteroids flying around in all directions colliding with other asteroids and planets not caring about the destruction they might convey. Our planet Earth is caught right in the middle of all of this action and is liable to entire extinction of any life forms on the planet if a large enough asteroid crosses its path. Any one single asteroid has the possibility to erase thousands of years of history and wipeout the human race as we know it. Asteroids are large or small chunks of rock and metal flying around space up to speeds of 80 000 km/h. These chunks were believed to have formed millions of years ago during the big bang. These rocks ...
