[218] [219] According to the threshold "nuclear winter" computer models, [3] [14] if one to five teragrams of firestorm-generated soot [30] is injected into the low stratosphere, it is modeled, through the anti-greenhouse effect, to heat the stratosphere but cool the lower troposphere and produce 1.25 °C cooling for two to three years; and ...
Foxfire, also called fairy fire and chimpanzee fire, [1] is the bioluminescence created by some species of fungi present in decaying wood. The bluish-green glow is attributed to a luciferase, an oxidative enzyme, which emits light as it reacts with a luciferin. The phenomenon has been known since ancient times, with its source determined in 1823.
Ecosystem decay is commonly caused by the harvesting of rain forest in appliance to certain laws or illegally for profit by humans. Certain countries such as Brazil prohibit the harvesting of Brazil nut trees and groves of this species causing forest fragmentation and thus causing ecosystem decay to occur. Cities, roads, farms and any other ...
In this type of free neutron decay, in essence all of the neutron decay energy is carried off by the antineutrino (the other "body"). The transformation of a free proton to a neutron (plus a positron and a neutrino) is energetically impossible, since a free neutron has a greater mass than a free proton. However, see proton decay.
The scarecrow suddenly turns into a snowman. Billy is soon confronted by the sinister Old Man Winter who chases after him. He tries to take shelter in several trees, but is kicked out by the owners each time...save a hospitable skunk whose scent Billy spurns. Old Man Winter corners Billy within a hollow tree trunk, trapping the cub with icicles ...
Burn-in on a monitor, when severe as in this "please wait" message, is visible even when the monitor is switched off. Screen burn-in, image burn-in, ghost image, or shadow image, is a permanent discoloration of areas on an electronic visual display such as a cathode-ray tube (CRT) in an older computer monitor or television set.
Distance decay is a geographical term which describes the effect of distance on cultural or spatial interactions. [1] The distance decay effect states that the interaction between two locales declines as the distance between them increases. Once the distance is outside of the two locales' activity space, their interactions begin to decrease.
Speculatively, it is possible that the universe may enter a second inflationary epoch, or assuming that the current vacuum state is a false vacuum, the vacuum may decay into a lower-energy state. [15]:§VE It is also possible that entropy production will cease and the universe will reach heat death. [15]:§VID
