- 3051: I.t. Doctors Database Analysis
- ... Technology could be used in a Doctor s surgery to computerise the patients files, to print out prescriptions and certificates for things like immunisations. The patients file would consist of their name & address, telephone number, D.O.B, sex, allergies, and diseases. In addition, it will be faster for the doctor to access his or her files because they are all just a few clicks of a mouse button away instead ... of hassle and waste a lot of time, wouldn t it? The doctor would get annoyed searching for people s files and they would take longer to get through things, which means less appointments every day. The dilemma is that I need to make a database to answer all these problems. I will make a database for a doctor s surgery so the doctors can look up and alter the files ...
- 3052: Humpback Whales
- ... fish. Concentrated massses of prey are preferrable for this method of feeding. An average-sized humpback whale will eat 4,400-5,500 pounds (2000-2500 kg) of plankton, krill and small, schooling fish each day during the feeding season in cold waters (about 120 days). They eat twice a day. Humpbacks cooperate in hunting and have developed a method of rounding up highly concentrated masses of prey that is called bubble-net feeding. The hunting members of a pod form a circle 10-100 feet ... The baby is nurtured with its mother's milk and is weaned in about 11 months. The mother and calf may stay together for a year or longer. Calves drink 100 pounds of milk each day. Humpback whales reach puberty at 4-7 years old, and maturity at 15 years. A calf is born to a female every 1-3 years. LIFE SPAN Humpback whales have a life expectancy of ...

- ... in his monkeys to be Simian Fever, one harmless to humans. After getting the word from USAMRIID that he may actually be dealing with Marburg, a filovirus lethal in humans, Dalgard was a frightened. He'd heard about the effects of Marburg on the human body, not only would he loose his monkeys, but also he was putting himself and his employees at risk. When he later received a call from the Institute stating that he may actually have a monkey house infected with Ebola, unlike Johnson, he knew nothing about this virus! He'd thought Ebola to be no more dangerous than Marburg. Dalgard did not fully realize the agent he was dealing with. He knew nothing of the "crashing and bleeding out", or liquefying of the internal organs ... death bed. She sacrificed being with her dying family member to potentially save the human race. Last, there was the character of Dr. Joseph B. McCormick, chief of the Special Pathogens Branch of the C.D.C., who perhaps, in a sense, personifies the human race's attitudes toward nature. McCormick, like Gene Johnson, had been to Africa and treated patients suffering from Ebola in Sudan. He had spent days ...
- 3054: Fusion 2
- ... deuteron (the nucleus of the deuterium atom) with a triton (the nucleus of a tritium atom). Both nuclei are isotopes of the hydrogen nucleus and contain a single unit of positive electric charge. Deuterium-tritium (D-T) fusion requires the nuclei to have lower kinetic energy than is needed for the fusion of more highly charged heavier nuclei. The two products of the reaction are an alpha particle (nucleus of the ... materials, or by the employment of "advanced" fusion-fuel cycles that do not produce neutrons, such as the fusion of deuterons with helium-3 nuclei. Nearly neutron-free fusion systems, which require higher temperatures than D-T fusion, might make up a "second generation" of fusion reactors). Finally, a fusion reactor would not release the gaseous pollutants that accompany the combustion of fossil fuels; hence, fusion would not produce a greenhouse ... plasma is kept generally stable both by an externally generated, doughnut-shaped magnetic field and by electric currents flowing within the plasma itself. (The basic concept of the tokamak had been first proposed by Andrey D. Sakharov and Igor Y. Tamm around 1950.) Since its development, the tokamak has been the focus of most research, though other approaches have been pursued as well. Employing the tokamak concept, physicists have attained ...
- 3055: From Legend To Science The Health Benefits Of Tea
- ... brewed; stories about tea's origins are more myth than reality. One story tells that a legendary Chinese leader and medical expert, Sheng Nong, discovered tea as a medicinal herb in 2737 B.C. One day while he was boiling water under a tea tree, some tea leaves fell into Sheng's pot of boiling water. After drinking some tea, he discovered its miraculous powers and immediately placed tea on his ... tea aids in quenching thirst and in digestion, checks phlegm, wards off sleepiness, stimulates renal activity, improves eyesight and mental prowess, dispels boredom and dissolves greasy food. One cannot do without tea for a single day. (Binglun 334) Zhang Binglun refers to modern studies that that lend scientific support to ancient claims of tea‘¦s medicinal properties: ‘§Experiments made on guinea pigs reveals two-thirds less fatty acid in the faeces ... Today (May ‘V June, 1999) an article on tea discusses ‘§an explosion of research" which indicates that, tea, particularly green tea, provides numerous health benefits. Studies show that drinking four cups of green tea a day can reduce the risk of developing stomach and lung cancer as well as heart disease. (Chatterjee 26) The Journal of Alternative Therapies reports the results of a recent Dutch study showing that the flavonoids ...
- 3056: Frog Disection
- ... walls of the small intestines. The waste left over is moved into the large intestine where water is reabsorbed. Then the waste is eliminated through the cloaca and the anus. (Cooper, H, Hays, S, Walker.D, Linden R 1982) The frog has three lobed livers. The functions of the liver, is to release digestive enzymes to help the stomach and the small intestine with mechanical digestion. The gall bladder stores bile ... rapidly and efficiently through a closed circulatory system. It consists of a very well developed system of arteries, veins and capillaries that reach all the living cells of an organism. (Cooper, H., Hays, S., Walker D., Linden R. 1982) The frog s heart consists of three chambers. The left atrium receives "oxygenated" oxygen rich blood from the lungs, while the right atrium receives "deoxygenated" oxygen poor blood, which returns from the ... bronchi. These tubes continue to branch, decreasing their size to form ducts called bronchioles. At the end of the bronchioles are sac-like lungs that are surrounded by blood vessels. (Cooper, H., Hays. S., Walker.D Linden R. 1982) Frogs have a single body cavity that contains the lungs and the viscera. Its vertebral bones are not attached to any ribs. Even with this, the frog can still pump air ...
- 3057: Flesh-eating Bacteria
- ... and anaerobic bacteria are burrowing through soft tissue. Once the tissue is destroyed, gas is accumulated in the muscle fibers and you may be able to smell a foul odor by the fourth or fifth day after infection (an x-ray usually reveals the buildup of gas before you can smell it). In early stages of infection, patients may have a low-grade fever, accompanying tachycardia, a little higher than usual ... door. No one entered her room unless they were wearing gloves and a gown. Penicillin was the drug of choice and was given to her in high doses up to even 40 million units per day administered through IV s. Since large amounts of extracellular fluid accumulated in Katie s interstitial spaces, the nurses had to closely monitor her hemodynamic status, her urine output, peripheral pulses, and vital signs among many ... Sadly the doctors were not able to prepare Katie to go home. Despite fasciotomy and the surgery, her infection continued aggressively. Her wound after surgery had a foul-smelling drainage, which increased in amount every day. Local cellulitis developed at the IV site on her arm. Just 10 days after the first surgery she underwent a second infection spreading around her hip area. Despite all efforts by Katie and the ...

Later scientist disproved this theory when more was learned more about genes and how they work. 50 years later Darwin came up with a theory that most scientist believe it to this day. this is called the theory of evolution. His book was called The Origin of Specie. Alfred R. Wallace, came out with a theory that was almost identical to Darwin s theory. Darwin s theory was ... the creator gave us Indian life; we walked and as soon as we saw the game and the fish we knew they were made for us. We grew and multiplied as a people. (Taylor Ph.D.) Another creation story is from the Iroquoian mythology. They thought sky women gave birth to twins. Their names were Iouskeha and Tawiscaron. Iouskeha was the good- minded twin, he was born normal and he made ...

- ... and Frances C. Minsters, 1977, p.8) The child does not fall to the ground, and recovery is prompt, although the attacks may occur repeatedly. The attacks can occur in fact many times in a day. Some people this type of generalized seizure call also daydreaming. The tonic-clonic seizure, that is a part of generalized seizures, was previously called grand mal. This seizure is dramatic. Grand mal is what most ... This tonic phase takes 30-60 seconds in which the body will shake. The person that will recover from such unconsciousness may be confused for several minutes and wishes to sleep for several hours. A day after, headache and soreness are common. There are also other varieties of epilepsy that are uncommon and they include myoclonic seizures, atonic seizures, and tonic seizure. The myoclonic seizure is sudden and symmetrical and may ... the most innovative medicines is the Tegretol XR. It is effective against partial onset seizures (focal, psychomotor,etc.) and tonic-clonic seizures.. Finally, for people who have large fluctuations of their blood levels during the day, the sustained release formulation may allow for smoother levels and reduce side-effects (SIU Center for Epilepsy, 1986, p.1). Epilepsy does not get worse as people get older. It remain and in fact, ...
- 3060: El-nino
- ... slows down to conserve the combined angular momentum. John M. Gipson of NASA's Goddard Space Flight Center in Greenbelt, Md., has tracked the planet's spin by monitoring changes in the length of the day. Over a typical year, the day shortens and lengthens by roughly 1 millisecond, mostly because of shifts in atmospheric angular momentum. During the current El Nino, the day has grown longer by four-tenths of a millisecond. Last year, Earth squeaked past the previous record high for globally averaged temperatures, continuing a balmy trend that has made this decade the hottest in ...
