- 6922: Lime Disease
- ... be an experimental study in which lyme disease treated pediatric populations will be examined to identify possible cognitive or psychologic abnormalities resulting from lyme disease. The focus will be on children because they have a high incidence of lyme disease? and are less likely to have cognitive deterioration due to confounding factors, such as aging. Children between the ages of 5 and 15 who have been treated with lyme disease will ...
- 6923: Lift, Weight, Thrust And Drag
- ... surfaces of the wing are not the same. Although several factors contribute to this difference, the shape of the wing is the principal one. The wing is designed to divide the airflow into areas of high pressure below the wing and areas of comparatively lower pressure above the wing. This pressure differential, which is created by movement of air about the wing, is the primary source of lift. The weight of ...
- 6924: Lichens
- ... through small openings in the ground. Few grow near cities because most cannot survive in industrial air pollution. There are notable exceptions, however: in England, for example, Lecanora conizaeoides is actually confined to areas of high pollution.

The second thing it may do is if it is at its highest state it can fall spontaneously to its lower state thus emitting light. The third ...
- 6926: Lasers 3
- ... research instruments. They are tunable, as are dye lasers, and in theory a small number could cover the entire spectrum from infrared to X-rays. Free-electron lasers should also become capable of generating very high-power radiation, which is currently too expensive to produce. Laser Applications The use of lasers is wide spread and is now days becoming a commonly known tool. Lasers have become valuable tools in industry, scientific ...
- 6927: Lasers
- ... measuring and guiding. An object s distance can be determined by measuring the time pulses of the laser light. They can even use a laser to measure the distance to the moon. Scientist use a high powered laser to determine the distance. People use laser beams in guiding because they produce a straight line, which is a valuable tool for guidance. Construction workers use beams to align walls, ceilings, sewer pipes ...
- 6928: Larnyx Cancer
- ... by local therapy or systemic therapy. In local therapy there is a choice of radiation therapy, surgery, or a combination of both. The only choice in systemic therapy is chemotherapy. When radiation therapy is used high-energy rays damage the cancerous cells and stops them from growing larger. A patient treated by radiation has a better chance of keeping his or her voice after the treatment. Treatment usually last for five ...
