As the growth of renewable energy sources, such as wind, solar, and ocean wave, increases, their impact on the electrical grid has been rapidly escalating. Although renewable resources have been able to offset some traditional generation, they have also brought a need for increasing reserve capacity due to their non-dispatchable,...
With the recent interest in increasing the penetration of renewable energy sources onto the power grid, there has been an unprecedented rapid deployment of wind generation, especially in the US Pacific Northwest. While wind farm developers have continued to expand their operations, power system operators are left to deal with...
A branch mortality dating technique and whorl
sampling strategy were implemented to model five-year
crown recession from data collected on temporary
plots. Twenty-eight Douglas-fir from two levels-of-growing-
stock studies in Oregon and Washington were
first dissected to validate the proposed dating
technique and assess alternative sampling strategies.
Branch mortalities in...
Volatile organic compounds (VOCs) play an integral role in climate change and as a carbon source for organisms living in a marine environment. These compounds have many sources, but the impacts of biogenically produced VOCs is not fully known. Phaeodactylum tricornutum was studied under axenic ideal growth conditions to determine...
This study is an archeological testing report for the Willamette
Mission Hospital Site. Landform analysis, photointerpretation and historical
research were integrated with anthropological theory for this
study.
The site is an invaluable data base to further the study of human
adaptability and cultural change. It should provide an excellent context...
Alternating-current thin-film electroluminescent (ACTFEL) devices are used in the
formation of pixels in flat panel displays. ACTFEL flat panel displays have many
advantages over other flat panel technologies. Specifically, ACTFEL panels are emissive
displays, they have high brightness, wide viewing angles, and rugged construction.
Although much is already known about...
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...
Growth trials are described for a series of artificial diets designed for the lobster, Homarus americanus. Methods of preparation and ingredients used for each of the manufactured feeds are presented. Details of experimental conditions are provided and results of growth trials are discussed. The influence of animals of differing genetic...
Photosynthetic diatoms and marine bacteria contribute about one third of the net primary production in marine environments. Understanding the interactions between these two organisms is potentially important to the over all flow of carbon in the marine ecosystem.
