The relative resistance of the coho salmon (Oncorhynchus kisutch) and the chinook salmon (O. tshawyscha) to the parasitic larvae (glochidia) of the freshwater mussel (Margaritifera margaritifera) was studied in an attempt to determine why the coho appeared to be more resistant. Natural and acquired antibody was sought in the mucus...
We describe two combinatorial problems in the theory of automorphism groups of compact Riemann surfaces of genus two or greater: enumerate the topological actions of a finite group on surfaces and determine the set of genera of surfaces admitting such a group action, called the genus spectrum. We illustrate results...
Metal organic Frameworks (MOFs) that experience stimuli induced structural transformation could enable a whole new class of materials with remarkable properties. Photoactuating moieties in the structure could effect changes in the pore space or macroscale shape change enabling light driven gas separation and actuators. Here, we present a novel approach...
Volcanic hazard maps inform the public on the nature and extent of the hazards that threaten them, but these maps are often challenging for those who are not trained in map use or geology. The maps in this study focus on lahars, a dangerous, fast, and far-reaching volcanic hazard that...
A hydraulic power-take-off was designed and built for outboard
engines typical of those used on small boats and Pacific City-type
dories. An associated hydraulic system was developed for use on
these boats to provide power for fishing machinery. The power for
each system was provided by a hydraulic pump direct-drive...
