  2. Decay theory - Wikipedia

    en.wikipedia.org/wiki/Decay_theory

    The decay theory proposed by Thorndike was heavily criticized by McGeoch and his interference theory. [5] This led to the abandoning of the decay theory, until the late 1950s when studies by John Brown and the Petersons showed evidence of time based decay by filling the retention period by counting backwards in threes from a given number.

    en.wikipedia.org/wiki/Decline_effect

    In its more general term, Cronbach, in his review article of science "Beyond the two disciplines of scientific psychology" referred to the phenomenon as "generalizations decay." [1] The term was once again used in a 2010 article by Jonah Lehrer published in The New Yorker. [2]

    where k is the reaction rate constant. Such a decay rate arises from a first-order reaction where the rate of elimination is proportional to the amount of the substance: [39] =. The half-life for this process is [39] = ⁡.

  6. Ecosystem decay - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_decay

    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 ...

    A fresh pig carcass. At this stage the remains are usually intact and free of insects. The corpse progresses through algor mortis (a reduction in body temperature until ambient temperature is reached), rigor mortis (the temporary stiffening of the limbs due to chemical changes in the muscles), and livor mortis (pooling of the blood on the side of the body that is closest to the ground).

  9. Lambda - Wikipedia

    en.wikipedia.org/wiki/Lambda

    In neurobiology, lambda denotes the length constant (or exponential rate of decay) of the electric potential across the cell membrane along a length of a nerve cell's axon. In the science and technology of heat transfer, lambda denotes the heat of vaporization per mole of material (a.k.a. its "latent heat"). [27]
