... for the remains of a downed Marine C-46 transport, lost somewhere in the Mount Ranier area, a young Idahoan businessman named Kenneth Arnold spotted something that would change his life forever. Just north of his position flying at an altitude of 9,500 feet and an unprecedented airspeed of 1,700 mph he spotted nine circular aircraft flying in formation. According to his estimate the aircraft were approximately the size of a DC-4 airliner ( Jackson 4). This account was the first sighting to ever receive a great deal of media attention. This sighting gave birth to the phrase "flying Saucer" coined by a reporter named Bill Begrette. Although not the ...

... However, in the 1960s the American falcon came close to extinction. Most of the damage was done by poisons that farmers used to kill insects. The worst poison was DDT. By the time naturalists learned of DDT's effect on wildlife, it was almost too late. The American peregrine's scientific name is Falco peregrinus anatum. At one time, people called this falcon a duck hawk. That was a poor name, since falcons aren't hawks and they rarely kill ducks. The American peregrine was once found all across the eastern United States and southern Canada. In the west, the species was found from Mexico to California. DDT poisoning hit this subspecies the hardest. ...



Digital Television

... this perk is the fact that digital signals have a higher bit rate. This allows for more bits to be transmitted into the TV (cable, antenna, or satellite). The more bits a TV can transmit, the better the picture or screen resolution. The digital TV signal can carry as many as 19.4 megabits of data, which means a broadcaster can mix multiple programs of varying bit sizes onto a single channel. Say you’re watching a football game, since one camera view only uses up so many bits, you can select a different camera angle while watching the same game on the same channel. It is possible for a network, like NBC, to show two different programs at the same time on the ...



Down Syndrome 3

... genetic cause for Down syndrome is when a person inherits all or part of an extra copy of chromosome 21. Trisomy 21, the inheritance of an entire third copy of this chromosome, accounts for 95 percent of Down syndrome cases. Two other abnormalities each account for 2 to 3 percent of all cases. The first, translocation, takes place when a child inherits an extra piece of chromosome 21 attached to a different chromosome. The second, called mosaic Down syndrome, results when only some cells in the body have the extra chromosome. There is no cure for Down syndrome although prenatal tests are available to identify fetuses with the disorder. Down syndrome can be diagnose ...



The Tiger

... Tigers undertake long migrations. These migrations occur when epidemics wipe out the prey populations. This type of migrations happens often. Temperatures down to -45 degrees Celsius are not harmful and do not dampen their activities ( Mammals Multimedia Encyclopedia 1990). Tigers usually live and hunt alone. When they hunt they can leap 5 to 6 or jump as far as 10 meters. Tigers do not usually prey on people, but some do become man eaters. If a Tiger becomes a man eater it is because of a wound, weakness, or just because it is to old. The young accompany their mother on the hunt when they are 5 to 6 months of age. Tigers begin to hunt alone when they ...

... genes known. Dystrophin is largely responsible for reinforcing and stabilizing the sarcolemma. Dystrophin associates with the muscle fiber sarcolemma by interacting with the actin microfilaments and with a transmembrane protein complex linked to the extracellular matrix. This latter dystrophin-associated glycoprotein complex (DAGC) includes the extracellular proteoglycan, [Alpha]-dystroglycan, which binds to merosin in muscle fiber basal laminae, as well as a number of other integral and cytoplasmic membrane proteins: [Alpha]-dystroglycan; [Alpha]-, [Beta]- and [Gamma]- sarcoglycans (see Figure 1). The DAGC provides a physical link and, potentially, a sig ...
