Evaluation of Pacific Lamprey Entosphenus Tridentatus Anatomical Structures as Records of Age and Isotope Histories

Creator:: Pelekai, Keala N.
Abstract:: The anadromous Pacific Lamprey (Entosphenus tridentatus) is a biologically and culturally important species native to the North Pacific Ocean and its adjacent freshwater tributaries. Pacific Lamprey have experienced declines in abundance and distribution throughout their native range, highlighting a need for further research on the species to better inform conservation...

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...

Organic Pelletized Chicken Manure Application Rates and Effects on Novel Asian Vegetables in the Willamette Valley

Creator:: Velazquez, Hannah D.
Abstract:: Daikon, mizuna, mizspoona, and komatsuna are novel Asian vegetables for which a market exists in Oregon, especially in the organic sector. However, these crops are currently not grown widely in the area, despite the favorable growing environment of Oregon’s Willamette Valley. Little is known about the appropriate application level of...

CO₂ capture from wet flue gas using a water-stable and cost-effective metal-organic framework

Creator:: Loughran, Ryan P.
Abstract:: We report the use of MIL-120 as a water-stable and cost-effective metal-organic framework (MOF) for selectively capturing CO₂ from wet flue gas. Synthesized using inexpensive and environmentally benign reagents in water, MIL-120 possesses one-dimensional pores decorated with hydroxyl-bridged Al(III) ions and benzene rings with an interstitial spacing of 4.78 Å....

Elicitors: A Novel Tool for Controlling the Colorado Potato Beetle Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae)

Creator:: Butcher, Alexander M.
Abstract:: 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...

Grazing Effects on Fuels and Plant Community Characteristics across Three Community Types in Wyoming Big Sagebrush Steppe

Creator:: Thomas, Tyler W.
Abstract:: Livestock grazing is the prominent land use in Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) steppe and has been present since the late 1800’s. There have been calls to remove livestock grazing from rangelands as historic grazing practices resulted in the degradation of some...

The Effects of Structure and Volcanic Stratigraphy on Groundwater and Surface Water Flow: the Hat Creek basin Case Study, California, USA

Creator:: Marcelli, Marina F.
Abstract:: Hydrogeologic systems in the southern Cascade Range develop in volcanic rocks where volcanic morphology, stratigraphy, extensional structures and attendant basin geometry play a central role in groundwater-flow paths, groundwater/surface-water interactions, and spring discharge locations. High-volume springs (> 3 m3/s) flow from young (< 1 Ma) volcanic rocks in the Hat...

Synthesis and Characterization of an Ultrafine-Grained Aluminum-Copper System through High-Pressure Torsion

Creator:: Liang, Guangyuan
Abstract:: Aluminum and copper and their alloys have been widely used due to relatively high strength-to-weight ratios compared with conventional steels. Processing of these alloys is typically conducted at high temperatures over extended time periods. High-pressure torsion (HPT) is a promising processing technique for introducing significant grain refinement leading to excellent...

The Development of a Hybrid Particle-in-Cell Simulation Code in C++ for the Modeling of the SPT-70 Hall Thruster

Creator:: Myers, Conner J.
Abstract:: In order to support the growing satellite propulsion industry, a hybrid Particle-In-Cell (PIC) simulation with fluid treatment of electrons and neutral particles was developed to model the SPT-70 Hall thruster. The 2D, C++ code assumes azimuthal symmetry and a uniform magnetic field in the radial direction with the simulation domain...

Comparing Random and Nonrandom Spatial Patterns of Artifacts within Lithostratigraphic Unit 3 at Cooper’s Ferry, Idaho

Creator:: Gregory, Alex R.
Abstract:: Archaeological investigations at the Cooper's Ferry site in Western Idaho have recovered cultural remains dating to 16,000 years ago, suggesting the oldest human occupation recorded in North America. However, many archaeologists have argued the initial peopling of North America occurred no earlier than the opening of an ice-free corridor between...
