.... down carbohydrates into glucose, which is absorbed into the blood in the small intestine. People who don't have rely on insulin, a hormone made in the pancreas, to move glucose from the blood into the body's billions of cells. But people who have either don't produce insulin or can't efficiently use the insulin they produce. Without insulin, they can't move glucose into the cells. Glucose accumulates in the blood, a condition called hyperglycemia ("hyper" = too much, "glycemia" = glucose in the blood). Hyperglycemia causes intense thirst, the need to urinate frequently, blurred vision, fatigue, and other symptoms. Over time, high blood glucose can cause very serious me ....

.... of creating a hole in the skull. Scientists believe that this procedure was done in order to let out the evil spirits which doctors thought possessed the mentally ill of this time. The literature of ancient Greece also contains evidence of the belief that evil spirits or demons controlled the mentally ill. Not only the Greeks believed in the evil spirit theory, writings from the early Babylonian, Egyptian, and Chinese civilizations have also shown evidence that was believed to be a possession by demons-using beatings, restraint, and starvation to try to drive out the evil spirits. These beliefs somewhat cooled down as time continued to move on, but once again popped up as ....

.... the smallest estimate, that's a lot of tossing and turning. These estimates are usually based on the number of serious cs, the definition of which varies considerably. Some doctors define cs as those who cannot sleep at all; other are willing to categorize cs as all those who merely complain about their sleep. The currently accepted definition, to become known as DIMS (Difficulty Initiating or Maintaining Sleep). Several surveys have tried to pin down the exact cause of sleep problems. Of 1,000 households, one third had someone with current problems and in 42 percent someone had suffered from sleep disorders at sometime. Some doctor's polls have been revealing yet ....

.... (Integrated Services Digital Network)? ISDN is a system which provides digital capacity i.e. voice, video and data transmission in digital form, to be sent and received by a customer. Unlike stand alone services such as telephone, telex, fax and data communications, ISDN is a network which can offer all these services as a package in which a user can talk, exchange data, faxes and other documents at the same time, instead of having to use different networks for these services. 3. What is Satellite Communications? This is the use of orbiting satellites to relay microwave transmissions from earth stations to the satellite an to re-transmit those signals back down to ano ....

.... chemicals. Test results may be an instrument reading, and observation of a physical property, or a chemical reaction. Reactions used in qualitative analysis may attempt to cause a characteristic color, odor, precipitate, or gas appear. Identification of an unknown substance is accomplished when a known one is found with identical properties. If none is found, the uknown substance must be a newly identified chemical. Tests should not use up excessive amounts of a material to be identified. Most chemical methods of qualitative analysis require a very small amount of the sample. Advance instrumental techniques often use less than one millionth of a gram. An example of th ....

.... has many basic units like the meter, centimeter, kilometer, and the light year. Mass has kilograms, milligrams, centigrams, and grams. Density has mass and volume and temperature has Celsius, which is much easier to read than Fahrenheit. Fahrenheit is hard for many people to understand and translate because it is not read in increments of one. Instead it is read having thirty-two degrees Fahrenheit being zero and two hundred and twelve degrees being the boiling point, While the Celsius (metric unit of measure for temperature) is read with one degrees Celsius being the freezing point of water, and one hundred degrees Celsius being the boiling point. I think that should be ....

.... that survive this “marriage flight” cast off there wings and instinctively begin to look for a spot to start a new ant colony. After making a nest, the young queen ant seals off the entrance and begins to lay eggs. Some of the first batch are eaten by the queen for nourishment. When the surviving eggs hatch they become like larvae. After a few weeks each larva spins a cocoon around itself and pupates. In a few more weeks, adult workers emerge. It is their job to hunt for food and make the nest bigger. More workers will develop and the colony gets very organized. The new workers will completely take over as caretakers of the eggs, larvae, and pupae. Now ....

.... In instances when animals are used for experimentation there is always a risk. This risk involves the animals life and its right to co- exist with humans. That is the same right that we have to be free and choose our actions. In our past history and even still to this very day risky experiments are done on animals. The thousands of animals put to suffer outweighs any of the research that has been gotten from them. Peter Singer the author of a piece called “Animal Experimentation” in the book Intervention and Reflection displays and evokes the actual suffering of many harmless animals. "In 1953 R. Soloman, L. Kamin, and L. Wynne, experimenters at ....
