This thesis discusses the design of several microchannel solar receiver devices for use in CSP (concentrated solar power) using CFD (computational fluid dynamics) simulations. The goal is to demonstrate that, by taking advantage of the higher heat transfer coefficienct of microchannels, solar receivers can achieve higher efficiency than current receiver...
Environmental factors such as temperature, air, and water can have a profound
effect on the durability of asphalt concrete mixtures. In mild climates where good
quality aggregates and asphalt cement are available, the major contribution to
deterioration may be due to traffic loading and the resultant distress is manifested
in...
The peripheral-type benzodiazepine receptor (PTBR) of trout brain was
pharmacologically characterized and pyrethroid interaction with this site
investigated. High-affinity binding sites for [³H]PK 11195 were detected in brain
membranes of rainbow trout; these shared some of the characteristics of the
PTBR of rodent brain (i.e., high affinity for PK 11195...

The hypothesis that inoculation of transplants with vesicular-arbuscular mycorrhizal (VAM) fungi before planting into saline soils would alleviate salt effects on growth and productivity was tested on lettuce (Lactuca sativa L.) and onion (Allium cepa L.). A secondary hypothesis was that the fungi isolated from a saline soil would be...
People will spend a large amount of their lifetime indoors where the air is filled with both indoor and outdoor allergens. Exposure to allergens can have a range of effects on the health of building occupants. Textiles make up a vast majority of the surfaces, such as draperies, sofas, pillows,...
Few studies examine whether public attitudes toward forest management practices differ between public and private forests, with virtually no recent studies examining these differences in the Pacific Northwest, despite the coexistence of millions of acres of both public and private forest lands. Knowing whether public attitudes differ between public and...
This report presents tables of suspended-sediment data collected from 1956 to 1967 at 10 sites in the Umpqua River basin. Computations based on these data indicate that average annual suspended-sediment yields at these sites range from 137 to 822 tons per square mile.
Because available data for the Umpqua River...
