.... worry about, and it is also not the only thing that can be improved by the use of bicycles. There are several major problems that could be drastically reduced by the increased use of bicycles. Traffic would be a lot lighter due to the extremely small size of bicycles. It would also greatly reduce the wear and tear on our roads and highways, and therefore reduce government expenditure. But one of the most serious problems it would reduce is that of pollution and smog in out larger cities. There are more benefits to biking, though. There are benefits that come at a more personal level .....

.... a careful record of the dates of menstruation. A second assumption is that ovulation occurs 14 days before the onset of the next menstruation. The rhythm method is the most commonly used of the natural methods. To be used successfully a record should be kept for at least six menstrual cycles. The fertile period is then defined by a set of rules for example: The length of the shortest cycle less 18 days marking the start of the fertile period and the length of the longest cycle less 11 days marking the end of the fertile period. This is the only birth control method that has received th .....

.... CD's, there are writeable and rewriteable variations coming. DVD is just starting to make a significant impact on the market. Estimates vary from about 600,000 to 1,000,000 console players ("living room" boxes used strictly to play movies) sold in the United States through the end of 1998. So far, the number of DVD drives in PCs is far smaller. DVD technology can handle one or two layers of data per disc side. That makes for four sub varieties of DVD-ROM, the read-only version of this technology: DVD5 (single side, single layer) with a 4.7GB capacity; DVD9 (single side, dual layer), 8.5GB .....

.... and cancer. Should people be created for the purpose of dying? Many people believe it is unjust to use animals for testing various products for humans, such as makeup and shampoo. Creating life for the simple purpose of injecting a deadly disease in the body to find a cure is just? Another purpose of cloning may be for work labor. Should society create people to work for others like robots? People have different beliefs to answer such questions. A few people believe cloning can be helpful for those unexpected events resulting the death of a love one. If a brother or sister dies, should a pers .....

.... was in the water. We set out to sea around 5:00pm and returned at around 9:00pm. Those four hours were probably the best four hours of my adolescent life. When I was out on the kayak I saw so many killer whales it was unbelievable. We were in the midst of two whale pods numbering about 90 whales. I had heard that killer whales can attack people. Surprisingly, I was not afraid except for the fact of how cold the water was. It was so cold that if our kayak capsized both my father and I would have died in about 10 to 15 minutes from exposure to the freezing water. The experience was both .....

.... Their only chance was an abandoned to a abandoned Air Force airstrip. Unfortunately, the airstrip had been converted to a race track, complete with race cars, fences, and spectators. The 767 crash landed, and, fortunately, no one was killed. Their were many contributing factors that made this plane run out of fuel. First of all, the computerized fuel gauge was not working, and a maintenance worker said , incorrectly, that the plane was still certified to fly. To measure the amount of fuel remaining, they use a drip stick method. They discovered that their was 7 682 liters in .....

.... 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 this is mass spectrometry. Quantitative chemical analysis is used to determine the amounts of constituents. Most work in analytical chemistry is quantitative. It is also the most difficult. In principle the analysis is simple. One measures the amount of sample. .....

The earliest did not appear install the late mioceene period, Some 11 million years ago. Evans also the land animal that is new the closest to is hooted anim .....

.... phenomena currently unknown to science," the report stated, adding that such research could also improve understanding of, and in some cases debunk, supposed UFO events. For example, Earth science researchers have eventually accepted several phenomena "originally dismissed as folk tales," including meteorites and certain types of lightning, the panel noted. The findings are from a four-day workshop held in Tarrytown, N.Y., followed by a second three-day meeting in San Francisco, both last fall. The results are published in the current issue of the Society for Scientific Exploration, .....
