.... neurons and of brain chemicals, called neurotransmitters. Neurotransmitters transmit messages from one neuron to another. Two of these neurotransmitters are not produced in sufficient quantities in a depressed person’s brain. Because of this lack, too few messages get transmitted between neurons and the symptoms of depression occur. In Clinical depression the chemicals in the brain are out-of-balance. New technology allows researchers to take pictures of the brain that show activity levels in the brain. These imaging techniques such as f-MRI and PET scan actually create images of how active different parts of the brain are. Some studi .....

.... and despair that can become feelings of hopelessness and helplessness. Some of the symptoms of a depressive episode include anhedonia, disturbances in sleep and appetite, psycomoter retardation, loss of energy, feelings of worthlessness, guilt, difficulty thinking, indecision, and recurrent thoughts of death and suicide. The manic moods are made up by elevated or irritable mood, increased energy, decreased need for sleep, poor judgment and insight, and often reckless or irresponsible behavior. Bipolar affective disorder affects one percent of the population (approximately three million people) in the United States. It is presented by both .....

.... some extensive plead bargaining with them and some facts and pictures, they finally gave in and let me keep her. Well, not really though. I say that because my father of all people fell in love with "Molly" as she is now known. He has said on many occasions that Molly is the best dog he has ever had, and believe me, he has had many. The point is, APBT get a bad name because of the people who own them. In doing research for this paper I have become deeply fascinated with this breed and actually understand a great deal more about the APBT than the average person. But to understand more about the APBT, you must understand its history and .....

.... are being used by millions of people everyday, so with a CD-ROM drive and a antenna, you can hook up your laptop to your car with an antenna and have the same results as the ones that come with cars. Just because we have these in our cars however, doesn't mean that we won't get lost, but it is more difficult to get lost, and it's definetly easier to find your way around if you do get lost. When get in your car, all you have to do is type in your destination and the computer will show you where your destination is, aswell as how to get there and the easiest and fastest way to get there. These systems are being used to make everything .....

.... 2 fans. Within several additional seconds, two other shorted conditions occurred. Electrical shorts in the fan circuit ignited the wire insulation, causing temperature and pressure to increase within cryogenic oxygen tank 2. When pressure reached the cryogenic oxygen tank 2 relief valve full-flow conditions of 1008 psi, the pressure began decreasing for about 9 seconds, at which time the relief valve probably reseated, causing the pressure to rise again momentarily. About a quarter of a second later, a vibration disturbance was noted on the command module accelerometers. The next series of events occurred within a fraction of a .....

.... world to be tested and investigated to find medical uses. Lysergic acid deviates were found to relieve migraines and control postpartum hemorrhage because it causes veins to contract, but also caused gangrene of the limbs, and so further experimentation with the drug was abandoned. In the late 50's, however, LSD was used by the CIA as an interrogation drug for spies. However, it was proven to be unreliable and was later replaced with other interrogation drugs. LSD comes in the forms of crystals, liquids, tablets, gelatins, or blotting squares. The squares have designs on them such a flowers, dragons, shapes, animals, and cartoon cha .....

.... take chances on a daily basis. If you actually stop and think about it, life is one big game of chance. It is by chance that we are born, that we continue to survive, and that we will eventually die. Some people feel that this cycle occurs do to the will of God, others, like Charles Darwin believe that it happens based on chance or natural selection. Whatever you believe or disbelieve, life cannot be planned. No matter how hard a person attempts to "plan" their path in life, it is by chance and luck where that path takes us. Darwin's career was also based on chance, not planning. Darwin never planned to become a scienti .....

.... The main goal of Confucianists was to return a gentlemanly society to China. The core of Confucianism concerned social structure. Confucius taught that a man should respect and obey those of higher rank than himself, whether they be the father of a family, or the emperor of a nation. But even with absolute obedience, Confucianists believed that men should practice restraint and benevolence in those inferior to them. At the same time, those in high status were expected to lead virtuous lives, and to set examples for those that followed them. Confucianists believed that the moral code of man was set down by heaven, and if those in po .....

.... 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 the mouth of a fish, it passes through slits in the pharynx, flows over the gills, and exits at the back of the oper .....

.... of extinction. The Javan tiger became extinct in the 1970's in a set aside special national park under full protection. Politicans and bureaucrats seem to be obsessed with numbers and not trends. Let me illustrate this with tigers. There are frequently requests as to the exact number of tigers, or a tiger subspecies left in the world. That tells you that there are people that care. But there are so little tigers left that we can not even keep track of them. We should look at the trend that the population is taking, rather than the number as a slice in time. Just as you might say of a young member of the Hunt family, that they were ve .....
