- 831: Haloes Forecast Storms
- ... sun-widths). This is produced by sunlight passing through both the side and bottom of each crystal. Moonlight will also produce a halo, around the moon, with the proper layer of cirrostatus. Another common optical effect is known as "mock suns" or "sun dogs" or "parhelia" (Greek for "with the sun"). These bright spots on either side of the sun, outside of the halo, occur when sunlight passes through the sides ... sun. You can see haloes and mock suns more clearly if you block out your view of the real sun by holding your hand in front of it at arm's length. Another spectactular optical effect is the solar pillar. This is a vertical shaft of light the same colour as the sun stretching upwards from the sun and is most often seen at sunset or sunrise. It's produced by ...
- 832: Preference Reversal And Expert
- ... them (a situation of compatibility) than when asked to choose between them (a situation of non-compatibility). The development of expertise in avoiding preference reversal, then, would have to involve the circumvention of the compatibility effect. One possible way in which this could occur would involve subjects consistently selecting either payoff or probability as the critical factor in both choice and pricing conditions. By adopting a strategy of maximizing the chance ... the choice and pricing condition and giving that option the higher rating on both scales, preference reversal would be avoided. Conversely, considering only the greatest potential for gain in each condition would have the same effect. This strategy, however, would be susceptible to preference reversals in the other direction. In the first case of maximizing the chance of payoff, the safe bet (H) would be favored over the longshot (L) and ...

- 834: Anti-Matter
- ... both elements are released in a spectacular blast of energy. Electrons and positrons come together and vanish into high-energy gamma rays (plus a certain number of harmless neutrinos, which pass through whole planets without effect). Hitting ordinary matter, 1 kg of anti-matter explodes with the force of up to 43 million tons of TNT - as though several thousand Hiroshima bombs were detonated at once. So how can anti-matter ... stored? Space seems the only place, both for storage and for large-scale production. On Earth, gravity will sooner or later pull any anti-matter into disastrous contact with matter. Anti-matter has the opposite effect of gravity on it, the anti-matter is 'pushed away' by the gravitational force due to its opposite nature to that of matter. A way around the gravity problem appears at CERN, where fast moving ...
- 835: The Yellow Wallpaper: Women In Society
- ... Especially in the nineteenth century, women were repressed and controlled by their husbands as well as other male influences. In "The Yellow Wall-Paper," by Charlotte Perkins Gilman, the protagonist is oppressed and represents the effect of the oppression of women in society.

- ... type” (Henkel 9). Some exceptions are made when a gene from a potentially allergenic food , like peanuts, is transferred into another food, or if genetic engineering changes a foods composition significantly. Exceptions may be in effect for vitamins that are taken out and labels would be required. “ Some consumers and advocacy groups have concerns about the safety and environment impact of the new products and want them banned” (Henkel 8). Since ... reproduction methods aren't natural. Natural or not, the benefits shine through with the end results. “Tests are being done to detect abnormalities during pregnancy.

- ... 1994), in their study of wolves and caribou in Gates National Park and Preserve, showed that wolf predation can be an important limiting factor at low caribou population densities, and may have an anti-regulatory effect. They also state that wolf predation may affect the distribution and abundance of caribou populations. Bergerud and Ballard (1988), in their interpretation of the Nelchina caribou herd case history, said that during and immediately following ... under unfavorable conditions are more vulnerable to predation throughout their adult lives than those born under favorable conditions. This model would produce time lags between the proliferation of the predator and the prey populations, in effect generating recurring cycles. Boutin (1992) states that if this hypothesis is correct, the effects of food availability (or the lack of) should be more subtle than outright starvation. Relatively severe winters could have long- term ...
