Uranium mineralization of the metamorphic aureole of the Spirit pluton, Stevens County, Washington

Creator:: Mitchell, Terry Edward
Abstract:: 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...

R&D investment and productivity in the U.S. and Canadian food processing sectors

Creator:: Chan-Kang, Connie
Abstract:: 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...

Big huckleberry (Vaccinium membranaceum Dougl.) ecology and forest succession, Mt. Hood National Forest and Warm Springs Indian Reservation, Oregon

Creator:: Anzinger, Dawn
Abstract:: This thesis is an observational study that examines relationships between disturbance, forest stand development, and big huckleberry (Vaccinium membranaceum) fruit productivity and growth by combining ecological methods with the traditional ecological knowledge of Warm Springs ceremonial huckleberry pickers. Shrub fields of fruiting big huckleberry develop in early seral subalpine environments...

Special Nuclear Material Analysis Using Temporal Gamma-Ray Spectroscopy and Machine Learning Methods

Creator:: Curtis, Jessica R.
Abstract:: 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...

Transforming Protective Action Strategies for Radiological Emergencies—Exacting the Science of Sheltering-in-Place

Creator:: Smith, Todd R.
Abstract:: 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...

Regional variation of pull factors for retail sales in Oregon's nonmetropolitan counties 1979, 1982, 1984

Creator:: Corcoran, Patrick
Abstract:: 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,...

Database development and application to characterize juvenile Douglas-fir (Pseudotsuga menziesii [Mirb] and understory vegetation in the Oregon and Washington Coast Range Mountains

Creator:: Shula, Robert G.
Abstract:: 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)...

Regional patterns of alkalinity in Oregon streams: an overview of ecological regionalization

Creator:: Henderson, Sandra
Abstract:: While many geographers believe that the regional concept is central to geographic study, no definitive regional scheme exists. The criteria considered in each regional study will relate to a stated objective or study. Ecological regionalization is a major contribution by geographers to environmental studies. By examining spatial patterns of factors...

Creating Anthropomorphic Models with Mesh Phantoms in MCNP to Simulate Mammography

Creator:: Garcia, Jacqueline K.
Abstract:: Breast cancer is the most common cancer among women as it accounts for about 25% of all female cancer cases. Studies have shown that early detection of breast cancer increases the chances of a positive prognosis amongst patients therefore it is crucial to provide accurate diagnosis tools in routine exams....

SCALE 6 (TRITON) Simulations of Fission Product Gamma Line Emissions and their Comparison to Plutonium and Uranium Measurements

Creator:: Sanchez, Timothy J.
Abstract:: Thin foil samples of special nuclear materials (SNMs) were irradiated for 60s using a Mark TRIGA II reactor, and their associated gamma emissions were recorded with a count time of 60s following irradiation. A rapid pneumatic transfer system was used to irradiate the samples in front of beam port #4....
