.... The physical basis of depression involves neurotransmitters in the brain. Neurotransmitters are chemicals that carry messages from one nerve cell to another. Nerve cells do not touch. There are microscopic gaps between them called synapses. For a nerve impulse to travel from one nerve cell to another, the sending cell releases a tiny amount of one of the neurotransmitters, which transmits the signal to the second cell, and so on around the body. After a nerve impulse has been sent across a synapse, special enzymes clear away the neurotransmitter so that another impulse may be sent. The first antidepressants, monoamine oxidase (MAO) inhibitors, were discovered accident ....

.... amounts for cellular respiration. Aquatic animals, however, obtain oxygen from a different aquatic respiratory medium---water. The dissolved oxygen concentrations in an aquatic environment is much lower than the 21% oxygen concentration available in the atmosphere (Barstow et al. 1999), hence special problems pertaining to the acquisition of sufficient amounts of oxygen arise for aquatic organisms---namely fish. Fishes have had to develop adaptations that enabled them to adapt to this problem. Since water contains an insufficient concentration of oxygen, fishes use gills to obtain the required amount of oxygen---via the counter-current exchange process. As water enters t ....

.... missing an exit (Alman 7). One also experiences hypnosis just before falling asleep at night and again before becoming fully awake in the morning (Basic Information 1). Even though everyone experiences hypnosis at least twice daily, it is not a highly understood subject by most. To fully understand how hypnosis works, one has to understand the four different activity levels of the human mind. The first level is called beta. In beta the mind is in complete consciousness. Approximately 75 percent of this level is spent regulating vital bodily functions such as heartbeat, breathing, and digestion. The second state is called alpha. Alpha refers to when the mind is in 95 ....

.... reservoir of repressed memories, numerous personalities, past lives, and for some, mythical insights and occult truths. Thoughts of began in the 1970's with an Australian physician Franz Mesmer who would rely heavily on the power of suggestion. Franz's last name is where the term mesmerize came about. Later the term emerged through an English surgeon named James Braid. is a Greek word, which means sleep. Braid used it to describe the hypnotic state people would be in after . We now know that is not sleep, but an altered state of consciousness. Many people believe the is mythical and magical. Those supporting the mythical view of often cite studies which show t ....

.... as many as 30 million people may constantly be monitored in their jobs" (462). As computer systems become more sophisticated this number will drastically increase. As we enter this new age of technology we must remember that with more power comes more responsibility by employers and employees alike. Micheal J. Smith, a professor at the University of Wisconsin-Madison explains that knowledge can be used as a weapon or as a tool (DeTienne 462). For instance monitoring abuse can be found in the in the situation of airline agents. The agents discovered that by keeping customers on hold while finishing their work they could gain an extra 5-minute break (De Tienne 462). In th ....

.... too. All the burning that is required to turn the turbines releases much sulfur, nitrogen gases, and other pollutants into the atmosphere. The cleanest, cheapest, and least polluting power plant of the two types is the hydroelectric power plant. The main reason most countries use thermal versus the hydroelectric is because their countries don't have enough concentrated water to create enough energy to generate electricity. (World Book vol. 14, 586) Nuclear power plants generate only about eleven percent of the world's electricity. There are around 316 nuclear power plants in the world that create 213,000 megawatts of electricity. (INFOPEDIA) Radioactive, or nuclear, ....

.... by duplicating and improving what nature has to offer. As long as there are natural discoveries yet to be made, then there are cures only yet to be discovered. A trek to the peak of a snow-capped mountain or an Arctic voyage through glaciers and icy waters are the journeys that most would consider essential to life. Colin Fletcher was one to claim that wilderness is needed: “And when at last I walked on past the two juniper trees toward the far side of the plateau I found I was feeling sorry for any man who was not free to abandon whatever futility detained him and to walk away into the desert morning with a pack on his back.” Such experiences allow for one to g ....

.... worker, mad at a manager, decided to spoil a batch of chemicals in the plant. On the night of December 2nd, 1984, the unnamed suspect pumped large amounts of water into a chemical storage tank with a hose (Saxon, 1). The tank was filled with the gas Methyl Isocyanate (MIC), a chemical used in pesticides and very lethal to humans (Leonard, 3). Around 11:00 p.m., a worker noted that heat and pressure were building in a tank and called for assistance, but by then it was too late. At 12:56 a.m., the morning of December 3rd, a faulty valve ruptured, allowing the deadly gas to escape into the atmosphere and cause a huge vapor puff to fall onto silent, sleeping Bhopal ( ....
