We report new major element, trace element, isotope ratio, and geochronological data on the Galapagos
Archipelago. Magmas erupted from the large western volcanos are generally moderately fractionated tholeiites of
uniform composition; those erupted on other islands are compositionally diverse, ranging from tholeiites to picritic
basanitoids. While these volcanoes do not...
Purpose of the Study
There were two major purposes of this study. The first was to
determine which socio-economic and educational factors normally
available to Neighborhood Youth Corps personnel were associated with
success and failure in the out-of-school program. The second purpose
was to utilize these available socio-economic and educational...
This study of the immediate, localized effects of a small dredging
operation on the benthic invertebrate community in the shipping
channel of Coos Bay, Oregon, was designed: 1) to measure the extent
of the physical removal of benthic macro- and meiofauna by hopper
dredging; 2) to record the subsequent benthic...
Archaeological investigations of the Applegate Lake project area were conducted by the Department of Anthropology, Oregon State University Univerfrom 1977-1980. A cultural sequence believed to span over 8000 years was revealed from a series of six sites. Several of these sites contained lanceolate or leaf-shaped projectile points. A large serrated...
Over the last several decades, potato production has increased globally as it has been recognized as an important component to improving food security. However, potato production has been continuously challenged by pests. Current pest management practices rely heavily on chemical pesticides. Unfortunately, the overuse of pesticides can be harmful to...
Fuel qualification timelines for new fuel technology under ideal conditions can take between 20-25 years to be fully qualified from initial concept to deployment as full fuel assemblies. To reduce the timeline and costs, new separate-effects test and integral-effects test experiments, advanced instrumentation, and advanced modeling and simulation tools are...
We do not know how to align a very intelligent AI agent's behavior with human interests. I investigate whether—absent a full solution to this AI alignment problem—we can build smart {\ai} agents which have limited impact on the world, and which do not autonomously seek power. In this thesis, I...
Distance estimation is a key process for movement and spatial cognition. However, this process is hindered when navigating virtual environments in virtual reality (VR) due to the movement being exclusively visually simulated. In order to contribute to the understanding of how this hinderance effects our ability to estimate distances in...
Accurately describing drag and virtual mass forces in two-phase flows is crucial for high fidelity modeling of nuclear thermal hydraulic safety systems. This study compares existing drag coefficient correlations commonly used in computational fluid dynamics (CFD) applications for air bubbles to experimental data collected for ellipsoidal air bubbles of varying...
Native American traditional foodways serve as one of the most important resources for indigenous communities because these resources provide a variety of non-physical cultural assets and health benefits to Native groups through the medium of food. The demolition of North America’s foodways through colonization has had adverse effects on indigenous...
In the last decade, there has been renewed interest in the use of granulocyte transfusions to treat infections in individuals with compromised immune systems. However, granulocytes only remain functional for about a day after isolation and this short shelf life is a significant drawback. Cryopreservation would allow long term storage...
Indigenous knowledge (creation of human well-being with a modicum of Earth resources) in India was augmented in the twentieth century with new technologies. The new technologies have raised Indian well-being, but these
improvements has been insufficient to motivate Indians to choose families small enough to achieve human sustainability.

The number of wind turbines and wind farms in the Pacific Northwest has increased dramatically in the past six years, which represents a significant amount of electrical generation capacity connected to the public electric grid. However, the variable nature of wind sometimes introduces excessive power, or conversely shortages, in power...
A linearized baroclinic, spectral-in-time tidal inverse model has been developed for assimilation of surface currents from coast-based high-frequency (HF) radars. Representer functions obtained as a part of the generalized inverse solution show that for superinertial flows information from the surface velocity measurements propagates to depth along wave characteristics, allowing internal...
The Oregon Coastal Transition Zone (OCTZ) extends several hundred

Annual recruitment of the New Zealand longfin eel (Anguilla dieffenbachii) has decreased by around 75 percent since heavy levels of commercial fishing began in the early 1970s. Given the unsustainability of existing regulatory policy, a deterministic multiple-cohort bioeconomic model is developed and applied to this system to gain insight into...
As central-place foragers, seabirds from colonies located close to multiple and/or productive marine habitats might experience increased foraging opportunities and enhanced resilience to food shortages. We tested whether this hypothesis might explain divergent trends in 3 populations of black-legged kittiwakes Rissa tridactyla, a surface-feeding piscivore, in the eastern Bering Sea....
A novel thermal management approach is explored, which uses supercritical carbon dioxide (sCO2) as a working fluid to manage extreme heat fluxes in electronics cooling applications. In the pseudocritical region, sCO2 has extremely high volumetric thermal capacity, which can enable operation with low pumping requirements, and without the potential for...
The Bering Sea Shelf transitions from ice-free to mostly ice-covered and back again over each winter. Sea ice coverage and the timing of ice melt play a critical role in determining shelf structure and consequently ecosystem response during the spring transition and summer. In this study, a 2-km resolution ocean...
Improving the quality of education and encouraging students to stay in school is one possible strategy for reducing poverty and raising local well-being in rural areas. A potential obstacle to this strategy, however, is outmigration to metro areas due to the lack of demand for this better-educated rural workforce, and...
We hypothesized that changes in southeastern Bering Sea foraging conditions for black-legged kittiwakes (Rissa tridactyla)

The lakes, rivers and coastal waters of Oregon have long provided the state's residents
and visitors with unique recreational boating environs and opportunities. However, this popular
activity represents more than a form of recreation: boating is an important component of the
Oregon economy. Each year, boaters spend millions of dollars...
Microorganisms play key roles in ocean biogeochemistry. However, several
predominant groups of uncultured bacterioplankton thought to contribute to
important biogeochemical processes in the oceans are known primarily from gene
cloning studies. Although these studies have greatly expanded our view of
microbial diversity in the oceans, they are not quantitative and...
A computer model is developed to estimate the initial investment and annual operating costs of feedlot runoff control systems. Costs are estimated for complete control systems consisting of a retention pond, settling basin, clean water diversion-runoff collection structures, disposal site, and an irrigation system. The model requires design inputs and...

In endurance-trained men, an acute bout of exercise is shown to suppress post-exercise appetite, yet limited research has examined this response in women. The purpose of this study was to investigate the effect of exercise intensity on appetite and gut hormone responses in endurance-trained women. Highly-trained women (n = 15,...
Barotropic tidal currents flowing over rough topography may be slowed by two bottom boundary–related processes: tangential stress of the bottom boundary layer, which is generally well represented by a quadratic drag law, and normal stress from bottom pressure, known as form drag. Form drag is rarely estimated from oceanic observations...
Perdeutero-spiropentane (C₅D₈) has been synthesized and infrared and Raman spectra are reported for the first time. Wavenumber assignments are made for most of the fundamental vibrational modes.

Persistent, long‐lived, stationary sites of excessive mantle melting are called hotspots. Hotspots leave volcanic trails on lithospheric plates passing across them. The global constellation of fixed hotspots thus forms a convenient frame of reference for plate motions, through the orientations and age distributions of volcanic trails left by these melting...
Central place foragers, such as breeding seabirds, need to commute between their nests and foraging grounds, thus close proximity of the breeding colony to productive oceanographic features might be beneficial for seabird reproduction. We tested this hypothesis by investigating the at-sea foraging and breeding behavior of thick-billed murres (Uria lomvia)...
