Dangles and Guerold [[27]] found the same relationship for the freshwater amphipod Gammarus fossarum, and Graça et al. [[28]] observed that G. pulex ate twice as much when leaf material was conditioned.
The choice of materials is conditioned by their own ability to withstand the environment as well as by properties that make them useful to human beings.
There are the predictable academic caveats and qualifiers, including the need to further study why this actually happens — if, for example, salivary responses to material rewards are conditioned early in our development.
Spent nuclear reactor fuel and the waste stream generated by fuel reprocessing contain radioactive materials and must be conditioned for permanent disposal.
Coming from a Communist state where individual ambition wasn't rewarded but punished, where extra work resulted in no particular material gain, the refugees have been conditioned to do the bare minimum -- or nothing at all.
First, works of art are parts of the objective world and are conditioned by materials and energies of that world.
However, the vault and other stored collections have neither the space nor the resources to preserve the world's myriad foods, and much of this material is saved under conditions where it can remain stable but is unable to respond to changing environmental conditions or threats.
In short, we maintain that for purposes of molecular definition and delimitation of the taxon, the 1972 material is in poor condition.
(4) This bulk material is assembled under conditions in which cells can survive and grow.
The test material is incubated under anaerobic conditions in a liquid enrichment medium, PEB, containing sodium polypectate as the sole carbon source (Pérombelon & van der Wolf, 2002).
