... contains energy-giving substances that our bodies can store until we need this energy to use our muscles. When we do use our muscles within us, we may not always be sure that heat is given off. Our bodies do not burst into flames but the perspiration on our skin is a clue to what is happening. The movement of the windsurfer has a different explanation. The windsurfer is propelled along by a sail which collects mechanical energy from the winds that sweep along the water. This energy has been produced by the sun which warms the earth's surface and sets the air above in motion. The sun's heat comes to the earth as a form of radiant energy. When the heat reach ...

... from the Arabic al-kohl, which was a term used to describe eyeliner that Middle Eastern women wore. Later, the definition broadened to mean an exotic substance (Monroe 5-6). It was primarily used among ancient people for special ceremonies, magic, and medicine, and “by about 1500 BC, Egyptian doctors included beer or wine in about 15 percent of their medicines”(Monroe 8-9). Alcoholic beverages are produced through a process called fermentation using plants such as corn, rye, barley, potatoes, and grapes, and are classified by their types and proofs. Some types of alcohol are beer, ale, stout, porter, malt liquor, wine, whiskey, bourbon, gin, rum, b ...

... throat and eye irritation; leaf necrosis, reduced growth and growth abnormalities and drowsiness. Increasing levels of air pollution, particularly particulates from vehicles, are linked to increasing respiratory problems including asthma and this air pollution is thought to cause up to several thousand deaths and up to 20,000 hospital admissions every year. Acid rain is another serious problem, helped along with the increased usage of motor cars. The increased acidity of the precipitation is down to contamination by carbon dioxide, sulphur dioxide and nitrogen oxide, all of which the car is largely responsible for. During driving, a large percentage of lead is ...

... this, however, is that the entire digital effects and animation industry is still in its infancy. The future looks bright. How It Was In the beginning, computer graphics were as cumbersome and as hard to control as dinosaurs must have been in their own time. Like dinosaurs, the hardware systems, or muscles, of early computer graphics were huge and ungainly. The machines often filled entire buildings. Also like dinosaurs, the software programs or brains of computer graphics were hopelessly underdeveloped. Fortunately for the visual arts, the evolution of both brains and brawn of computer graphics did not take eons to develop. It has, instead, taken onl ...

Science Is occurring? - According to Accu-Weather, the world's leading commercial forecaster, "Global air temperatures as measured by land-based weather stations show an increase of about 0.45 degrees Celsius over the past century. This may be no more than normal climatic variation...and several biases in the data may be responsible for some of this increase." - Satellite data indicate a slight cooling in the climate in the last 18 years. These satellites use advanced technology and are not subject to the "heat island" effect around major cities that alters ground-based thermometers. - Pro ...

... that is going to be addressed, is the secrecy and Government coverup of UFOs. "National Security Agency, or NSA, an acronym often assumed by insiders to mean 'NEVER SAY ANYTHING' , (Stacey 40) " has been blamed for millions of UFO governmental cover-ups around the nation. "Our problem is with government secrecy, because it widens the gap between citizens and the government, making it much more difficult to participate in the democratic process (Stacey 40)," says Steven Aftergood while addressing UFO secrecy. The UFO enigma, or as it is formerly know as the "'Cosmic Watergate' : the ongoing cover-up of the government's knowledge about extraterrestrial UFOs and ...

... constantly searching for new improved catalysts which will improve efficiency or produce a greater yield. An acidic catalyst works due its acid nature. Catalysts are strong acids and readily give up hydrogen ions, or protons: H+. Protons can be released from hydrated ions, for example H3O+, but more commonly they are released from ionisable hydroxyl groups (R-OH) where the O-H bond is broken to produce R-O- and H+. When the reactant receives protons from an acid it undergoes a conformational change, (change in shape and configuration), and becomes a reactive intermediate. The intermediate can then either become an isomer by returning a proton to the catalyst, or it ...

... oxygen and blood moving through your system artificially, and get you to the cryonics center as quickly as possible. The optimum time from death to arrival at the center is less than an hour. Some patients have arrived as late as six hours after death. At the center, your body is put on a table in the perfusion room. A team of three or four technicians work to drain the blood out of your body and inject a cryoprotective agent to get as much moisture as possible out of the tissues, so the organ don't crack during freezing. The body is then dried and wrapped in a cotton sheet. It is placed, cocoonlike, into a standard sleeping bag, head first, with the open end ...

... Black Holes 1). The escape velocity is the speed at which one must be going to escape the gravity of the object in question(Intro. to Black Holes 1). The Earth’s escape velocity is seven miles per second(Intro. to Black Holes 1). This means that to leave the Earth’s gravitational pull, you must be able to travel at least seven miles per second(Intro. to Black Holes 1). To escape a black hole, your velocity must reach at least the speed of light(Intro. to Black Holes 1). Because the speed of light(186,000 miles per second) is not possible because you must have infinite force to achieve the speed of light, nothing can escape a black hole’s ...
