The material properties of the candidate fiber-reinforced composite materials
and different fabrication methods for fiber composites were discussed. The
improvement of the hand lay-up process for polyurethane impregnated Kevlar was
investigated. Testing samples for lab and prototype tests were fabricated by hand lay-up
process. The study showed that fiber composites...
Pacific whiting and its by-products were good raw materials for high quality fish sauce production. Heat stable and salt activated enzymes were responsible for autolytic activity in Pacific whiting and by-products. According to temperature profiles of raw materials at various salt concentrations, two fermentation temperatures, 35°C and 50°C, were selected...
The overall objective of the study is to measure changes in agricultural production and water use patterns under various water supply and allocation mechanisms. The methodology nests an economic model of on-farm decisions in a basin-wide hydrologic model. The economic model forecasts the use of applied water, technology and crop...
Analysis of the long-term spatial pattern and dynamics of hardwood patches in the Coast Range of Oregon provides numerous ecological insights. Natural and anthropogenic disturbances have contributed to the development of a patchy mosaic of vegetation types in the area. Some hardwood patches in the Coast Range may be the...
Water right marketing and transfers represent a resource reallocation
strategy that has received considerable attention in the American West owing to
nearly full appropriation of water in the region. Several western states permit
transfers between different uses and places of use thus allowing water to move to
higher-value economic activities....
Seasonal reducing conditions play an important role in the cycling of nutrients and soil pore water chemical constituents in the Willamette Valley. Long periods of soil saturation lead microorganisms utilizing organic matter as their carbon source to find alternative electron acceptors other than oxygen. Once oxygen has been depleted microorganisms...
