.... episode, the person has lack of energy, and either an appetite loss or gain. Manic depression is a recurrent illness, so a person usually has more than one episode. These episodes can last from weeks to months. They occur whenever and have no certain pattern. Sometimes a stressful life event can trigger an episode, and sometimes they just happen. If a person has more than four episodes a year they are known as “rapid cyclers”. This is more common in women. There is no exact reason for what causes manic depression, but some doctors say that it may be from imbalances of cert .....

.... attention is the accessibility of the systems. In today’s growing entertainment market, the difficulty in accessing video and DVD movies can play a large part in the decision of which component is right for the consumer.METHODSThe beginning of any research project is in the decision of a topic to research. I chose to research the differences between the VCR and DVD home entertainment systems because the intricacies of the systems and the ways in which they work greatly interest me. I began my work using ordinary encyclopedias, found in the Rosewood High School branch of t .....

.... (DEA,1). On April 16, 1943, while Dr. Hofmann was measuring a fresh quantity of LSD, he accidentally dosed himself and was overcome with confusion. He was then obligated to leave work due to “a sensation of mild dizziness” and “extreme activity of imagination.”(Discovery, 2) On April 19, 1943, at exactly 4:20 pm, Dr. Albert Hofmann ingested 0.25 mg. of liquid LSD and journeyed on the first intentional “acid trip.” In 1947, Dr. Hofmann’s employers, Sandoz Laboratories, began marketing LSD in Europe. It was introduced into the Unite .....

.... from 90 to 108, are known. 97Tc has a half-life of 2.6 x 10^6 years. 98Tc has a half-life of 4.2 x 10^6 years. The isomeric isotope 95mTc, with a half-life of 61 days, is useful for tracer work, as it produces energetic gamma rays. Technetium metal has been produced in kilogram quantities. The metal was first prepared by passing hydrogen gas at 1100C over Tc2S7. It is now conveniently prepared by the reduction of ammonium pertechnetate with hydrogen. Techne tium is a silvery-gray metal that tarnishes slowly in moist air. Until 1960, techne tium was available only in small amou .....

.... of 9,500 feet and an unprecedented airspeed of 1,700 mph he spotted nine circular aircraft flying in formation. According to his estimate the aircraft were approximately the size of a DC-4 airliner ( Jackson 4). This account was the first sighting to ever receive a great deal of media attention. This sighting gave birth to the phrase "flying Saucer" coined by a reporter named Bill Begrette. Although not the first UFO sighting in history, Kenneth Arnolds account is considered to be the first documented UFO sighting. The following day Mr. Arnold discovered t .....

.... plant that can be used for food, forage and oilseed crops. They first gathered several hundred halophytes and began testing these plants in the desert of Puerto Peñasco. They irrigated the plants daily by flooding the fields with seawater from the Gulf of California. The best halophytes produced roughly the yield of alfalfa using freshwater irrigation. In order to show that these halophytes could replace other crops for use they tested to see if the crops could feed livestock. The halophytes have protein and carbohydrates but they contain too much salt. This limits th .....

.... food is the primary source of cadmium exposure, since food materials tend to take up and retain cadmium. For example, plants take up cadmium from soil; fish take up cadmium from water, and so on. It is introduced into the environment from mining and smelting operations. Other cadmium emissions are from fossil fuel use, fertilizer application, sewage sludge disposal or galvanized pie corrosion. The largest source of these cadmium releases into the general environment is the burning of fossil fuels (such as coal or oil) or the incineration of waste materials. Cadmium may also esc .....

.... left behind. A trap may catch and digest up to three insects, after which the leaf turns black. Older leaves blacken and die regardless of how many insects are caught and the plant continually sends out new leaves during the growing season. Venus flytraps usually grow along the dampish edges of sandy, wet bogs or fens. The plant begins its growth each spring, sending out a resette of small leaves. Usually the plant flowers around April or May. Summer arrives and the plant produces its larger leaves, often on upright petrels. Some plants remain rosetted all season. With the ap .....
