Muitiregion annular geometry is a basic feature of energy removal
systems ranging from advanced heat exchangers to fission reactor fuel
rods. For the symmetric cases, the heat conduction through annular regions
is well defined. However, for a shift of an annular region, analysis
of the system must be made in...
Describing functions have traditionally been used to obtain the
solutions of systems of ordinary differential equations. In this
work the describing function concept has been extended to include
nonlinear, distributed parameter partial differential equations. A
three-stage solution algorithm is presented which can be applied to
any nonlinear partial differential equation....
Understanding the mechanisms regulating mitochondrial respiratory function and adaptations to metabolic challenges, such as exercise and high dietary fat, is necessary to promote skeletal muscle health and attenuate metabolic disease. Autophagy is a constitutively active degradation pathway that promotes mitochondrial turnover and is suppressed by insulin and activated by exercise....
Forested landscapes in the Pacific Northwest have changed drastically in the last Century with large-scale wildfires, and increased extent and frequency of commercial timber harvests. Thus, landscapes once dominated by older forest cover types became a matrix of younger forests with patches of older forests dispersed throughout. These younger forests...
One of the biggest hurdles for a juvenile salmonid (Oncorhynchus mykiss) is migrating downstream from freshwater spawning grounds to the ocean. Juveniles from wild broodstock were reared from the South Santiam River for more than 1 year at the Oregon Hatchery Research Center (OHRC) in Alsea, OR. The fish were...
In horticultural nurseries for container-grown plants, production and sales have been threatened by the presence of a quarantined plant pathogen, Phytophthora ramorum (causal agent of sudden oak death). Infested nursery beds are an important source of P. ramorum, which can initiate disease through movement with surface water to infect roots...
Research was carried out to determine the influence of increasing
the percentage base saturation of the soil on the yield of
the commercial strawberry. It was found that the effect of increasing
the bases in the soils was directly related to the original
percentage base saturation. When this original value...
The foundation upon which any cooperative rests is the economic need for it as a business enterprise. The existence of such a need cannot by itself provide the basis for a thriving cooperative. Not only mus.t the need exist, but the members or the promoters must through realistic and diligent...
