The platinum-group metals have been the subject of considerable discussion in the news media over the past few months, particularly because of their projected use as catalysts in automobile engines. Metals Week of August 27 shows that platinum commands a price of $176.00 per ounce, as compared to $150.00 per...
Several uranium anomalies, with concentrations of U₃0₈ that
average below 0.003 percent and reach maximums of 0.069 percent,
are associated with black, fossiliferous, pyritic parts of the Ordovician
Ledbetter Slate in northern Stevens County, Washington. The most
uraniferous parts of the slate occur in small (average of 5 by 30...
Steven Universe, a relatively new show from Cartoon Network, explores an unexpectedly complex understanding of gender through their main protagonists. Utilizing Judith Butler’s work on gender performativity and doing gender, as well as Daniel Dennett’s conception of the self as a theorist’s fiction, and Alexander Weheliye’s understanding of power and...
Increased competition brought about by trade liberalization has raised the stakes
for improving productivity in U.S. and Canadian food processing. A key element of
productivity growth is technological change, which in turn results from R&D investment.
The present study employs an econometric model to assess rates of technological change
and...
Under the reauthorized Magnuson-Stevens Act (MSRA), US fisheries management councils must specify an annual catch limit (ACL) for each managed species and institute accountability measures (AMs) to ensure that actual harvest will not cause the stock to be overfished. While the details of implementation are still being developed, a set...
Following thermal neutron induced fission, supervised machine learning and temporal gamma-ray spectroscopy methods were used to identify differences in the delayed gamma-ray spectra of Pu-239 and U-235. The temporal gamma-ray spectroscopy method takes advantage of the time-dependent decay of fission products. Employing Spearman's rank-order correlation coefficient and without prior knowledge...
Radiological emergency plans ensure that protective actions can and will be taken in the event of an accident. Principle protective actions for the early phase of an emergency are evacuation and sheltering-in-place. While evacuations are generally safe, there are deterministic, long-term health consequences from prolonged displacement that outweigh the stochastic...
The performance of pull factors for total retail sales in Oregon's
nonmetropolitan counties during the economic cycle of boom, bust, and recovery
of the early 1980s is examined for geographic patterns. One regional pattern and
several county patterns are identified and discussed. Counties having the highest
and lowest pull factors,...
The Regional Vegetation Management Model (RVMM) predicts the effects of associated vegetation on the growth and yield of young Douglas-fir (age [less than or equal to] 20 years) in the Pacific Northwest, and is a 'front-end' growth model for existing rotation-age growth models. Objectives of this thesis are to: (a)...
