The diffusion rate is proportional to (1) the surface area over which diffusion is occurring, and (2) the diffusion gradient (concentration difference of the diffusing material between the two points under consideration divided by the distance between the two point

Michael Kühnally and thus to develop and reproduce at the maximum rate. The adjustments they make may be immediate and obvious, for example, flight from predators, or longer-term, for example, entry into diapause to avoid impending adverse conditions. The nature of the response depends, obviously, on the natur

Michael Kühnsoon realized that there was no suitable text for the class I intended to give. The so-called "general" or "introductory" texts reflected the traditional taxonomic approach to entomology and contained relatively little information on the physiology and ecology of insects. This does not mean that the

Michael Kühnt would appear that the earliest insects were wingless, thysanuranlike forms that abounded in the Silurian and Devonian periods. The major advance made by their descendants was the evolution of wings, facilitating dispersal and, therefore, colonization of new habitats. During the Carboniferous and P

4 Specific Features of Coupled Fluid Flow and Chemical Reaction,tems lead to flow induced spatial reaction patterns. However, it is most likely to encounter overlapping end-member types within natural environments. Specific examples, presented here, are preferential flow path development and diagenesis due to thermal convection. Before proceeding to discuss indi
