The dc conductivity of single crystals of vanadium pentoxide
was measured in the three crystallographic directions. The temperature
range examined was -165°C to +25°C. The activation energy
of the conduction process was isotropic and found to be .56 ev. The
conductivity was anisotropic.
Measurements of the Hall effect were attempted...
The "cotton fur" (CF) condition in mink has been shown through
investigations at Oregon State University to have three basic causes,
viz.: 1) Feeding diets of fish comprising certain species of the cod
family, including: Pacific hake, Atlantic whiting and Alaskan pollock;
2) Inclusion of rancid fats in the diet;...
An economic survey of the commercial operators currently active in the Queensland Reef Line fishery has been carried out, as part of a research project aimed at evaluating options available to manage the fishery. We present the background analysis of the fishery used as a basis to develop the sampling...
Marine protected areas (MPAs), ideally, manage human uses that threaten ecosystems, or components of ecosystems. During several recent MPA designation processes, concerns have arisen over the scientific justification for no-take MPAs, particularly those that restrict recreational fishing for pelagic species. An important question is: under what conditions might recreational pelagic...
