A Generalized Scheme for Creating Regge Calculus Models of General Relativity

Creator:: Hanson, Ben R.
Abstract:: Solutions to Einstein's equations are usually found by considering ideal, simplified models. However, if the real world always matched ideal physics models, then farmers would milk black and white spheres. To combat this, Regge calculus was developed as a numerical approximation scheme for general relativity. In Regge calculus curved manifolds...

Prevalence of Blastocystis in Shelter-Resident and Client-Owned Companion Animals in the US Pacific Northwest

Creator:: Ruaux, Craig G. and Stang, Bernadette V.
Abstract:: Domestic dogs and cats are commonly infected with a variety of protozoan enteric parasites, including Blastocystis spp. In addition, there is growing interest in Blastocystis as a potential enteric pathogen, and the possible role of domestic and in-contact animals as reservoirs for human infection. Domestic animals in shelter environments are...

Agronomic biosolids application rates for dryland wheat across a range of northwest climate zones

Creator:: Sullivan, Dan M., Bary, Andrew I., Cogger, Craig G., and Shearin, Todd E.
Abstract:: Predicting agronomic rates is important to derive optimum economic and environmental benefits from biosolids fertilizer applications. We conducted this research to 1) evaluate dryland wheat response to biosolids applications over a range of climate zones in the Pacific Northwest and 2) compare agronomic application rates predicted from yield curves with...

Field microplot estimates of soil N mineralization for manured and non-manured soils

Creator:: Sullivan, Dan M., Cogger, Craig G., Bary, Andrew I., and Myhre, Elizabeth
Abstract:: Credits for available N from past manure applications are often used in nutrient management planning. However, it is difficult to verify the accuracy of these credits. The major objective of this study was to estimate long-term effects of manure application on soil N mineralization. Specific objectives were to: 1) estimate...

Cold Seep Epifaunal Communities on the Hikurangi Margin, New Zealand: Composition, Succession, and Vulnerability to Human Activities

Creator:: Bowden, David A., Rowden, Ashley A., Thurber, Andrew R., Baco, Amy R., Levin, Lisa A., and Smith, Craig R.
Abstract:: Cold seep communities with distinctive chemoautotrophic fauna occur where hydrocarbon-rich fluids escape from the seabed. We describe community composition, population densities, spatial extent, and within-region variability of epifaunal communities at methane-rich cold seep sites on the Hikurangi Margin, New Zealand. Using data from towed camera transects, we match observations to...

Temperature Evolution of Nonreacting Spark Kernels at Sub-Atmospheric Pressures

Creator:: Caplan, Daniel L.
Abstract:: In the event of a mid-flight flameout of a gas turbine engine, reignition is paramount to occupant safety. Ignition at high altitude can be challenging, due in part to the potentially lower ambient pressures. An understanding of the effects of sub-atmospheric pressures on the temperature evolution of spark kernels is...

Tracking North Pacific Humpback Whales To Unravel Their Basin-Wide Movements

Creator:: Palacios, Daniel M., Mate, Bruce R., Baker, C. Scott, Hayslip, Craig E., Follett, Thomas M., Steel, Debbie, Lagerquist, Barbara A., Irvine, Ladd M., and Winsor, Martha H.
Abstract:: In 2014, Oregon State University (OSU) initiated a multi-year project to study humpback whale (Megaptera novaeangliae) migrations in the North Pacific Ocean using satellite tracking technology in combination with genetic and photo-identification (photo-ID) analyses. The study is highly relevant to management, given the need for new information arising from the...

Milk Production, Pasture Performance, and Environmental Sustainability of Specialized Pastures

Creator:: Wilson, Randi L.
Abstract:: This study investigated the effects of diversification strategy through the inclusion of forb and legume based pastures in the feedbase of dairy cows on annual forage production, botanical composition, spring milk yield, N partitioning and methane emissions from dairy cows in Western Oregon. Using a randomized complete block design, 3...

Diversity Literary Awards: A Tool for Assessing an Academic Library's Collection

Creator:: Kristick, Laurel L.
Abstract:: Diversity literary awards and other sources were used to create a list of high-quality titles written by and about underrepresented groups. This list was used to assess the diversity and inclusiveness of the library collections of a land-grant university. Gaps in the collection and acquisition processes were identified and will...

Competing tradeoffs between increasing marine mammal predation and fisheries harvest of Chinook salmon

Creator:: Chasco, Brandon E., Kaplan, Isaac C., Thomas, Austen C., Acevedo-Gutiérrez, Alejandro, Noren, Dawn P., Ford, Michael J., Hanson, M. Bradley, Scordino, Jonathan J., Jeffries, Steven J., Marshall, Kristin N., Shelton, Andrew O., Matkin, Craig, Burke, Brian J., and Ward, Eric J.
Abstract:: Many marine mammal predators, particularly pinnipeds, have increased in abundance in recent decades, generating new challenges for balancing human uses with recovery goals via ecosystem-based management. We used a spatio-temporal bioenergetics model of the Northeast Pacific Ocean to quantify how predation by three species of pinnipeds and killer whales (Orcinus...
