Investigation of Drag Coefficient and Virtual Mass Coefficient on Rising Ellipsoidal Bubbles

Creator:: Dueñas, Alexander M.
Abstract:: 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...

The Kalispel Tribe of Indian’s Contemporary Usage of Traditional Foodways

Creator:: Hilborn, Alexander M.
Abstract:: 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...

Membrane permeability properties of human granulocytes

Creator:: Vian, Alexander M.
Abstract:: 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...

Wind ramp prediction

Creator:: Alexander, Chianna M.
Abstract:: 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...

Proximity to multiple foraging habitats enhances seabirds’ resilience to local food shortages

Creator:: Paredes, Rosana, Harding, Ann M. A., Irons, David B., Roby, Daniel D., Suryan, Robert M., Orben, Rachael A., Renner, Heather, Young, Rebecca, and Kitaysky, Alexander
Abstract:: 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....

High-Flux Thermal Management With Supercritical Fluids

Creator:: Fronk, Brian M. and Rattner, Alexander S.
Abstract:: 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...

A high-resolution coupled ice-ocean model of winter circulation on the bering sea shelf. Part I: Ice model refinements and skill assessments

Creator:: Durski, Scott M. and Kurapov, Alexander L.
Abstract:: 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...

Foraging Responses of Black-Legged Kittiwakes to Prolonged Food-Shortages around Colonies on the Bering Sea Shelf

Creator:: Paredes, Rosana, Orben, Rachael A., Suryan, Robert M., Irons, David B., Roby, Daniel D., Harding, Ann M. A., Young, Rebecca C., Benoit-Bird, Kelly J., Ladd, Carol, Renner, Heather, Heppell, Scott, Phillips, Richard A., and Kitaysky, Alexander
Abstract:: We hypothesized that changes in southeastern Bering Sea foraging conditions for black-legged kittiwakes (Rissa tridactyla) have caused shifts in habitat use with direct implications for population trends. To test this, we compared at-sea distribution, breeding performance, and nutritional stress of kittiwakes in three years (2008–2010) at two sites in the...

Inhibition of pancreatic lipase by grape seed and tea extracts and their primary catechins in vitro

Creator:: Hess, Michelle M., Michels, Alexander J., and Frei, Balz
Abstract:: Inhibiting pancreatic lipase activity is an effective means of reducing fat absorption, which may have a role in combating obesity by limiting energy intake. The use of pharmaceutical lipase inhibitors has been limited due to the prevalence of undesirable side effects. Polyphenols represent an alternative strategy to inhibit digestive enzymes...

Recreational fisheries in the USA: economics, management strategies, and ecological threats

Creator:: Hughes, Robert M.
Abstract:: Recreational fishing has a long history in the USA, developing from the subsistence fisheries of Native Americans together with a partial subsistence fishery of later immigrants. Marine, diadromous, and aquatic taxa are targeted, including both vertebrates and macroinvertebrates. This paper defines recreational fishing, describes the main fishing techniques, identifies target...
