Impact of asset usage preferences on parallel replacement decisions

Creator:: Wagner, Tristan John
Abstract:: Data from a state department of transportation fleet shows that the usage of a typical asset decreases as it ages. One possible explanation for decreasing asset usage with age is operator preference for using the newest available asset. In this research the long-term cost and replacement implications of such a...

Contractile function and calpain activity in mouse skeletal muscle during hypoxia

Creator:: Hu, Hui
Abstract:: Calcium activated proteases, or calpains, are activated in cardiac muscles under conditions of ischemia/reperfusion and hypoxia. Their activity in skeletal muscle under similar conditions is poorly understood. We tested the hypothesis that hypoxia elevates calpain-mediated proteolysis in isolated glycolytic (extensor digitorum longus, EDL) and oxidative (soleus, SOL) mouse muscles studied...

Top-Down Effects of Wildlife and Bottom-Up Drivers of Soils and Productivity in Intensively Managed Forest Plantations in the Northern Oregon Coast Range

Creator:: Frey, David W.
Abstract:: In intensively managed forest plantations in the northern Oregon Coast Range, herbicides are often applied during site preparation and early stand regeneration to reduce competition for resources for planted conifer seedlings. In addition to reducing competition for crop trees, herbicide applications may affect soil processes including decomposition and nutrient cycling,...

Factors affecting coho salmon production in Oregon

Creator:: Scarnecchia, Dennis Leslie
Abstract:: Eight scale characters of known hatchery and wild coho salmon (Oncorhynchus kisutch) were compared, and a linear discriminant function was used to determine if hatchery and wild adult coho salmon could be correctly identified by their scales. Eighty-two percent of the hatchery and 89% of the wild fish were correctly...

Characterizing the Plant-Associated Symbionts, Rhodococcus and Agrobacterium

Creator:: Fuller, Skylar L.
Abstract:: Symbioses are a spectrum of interactions between organisms living in closeassociation. These intimate interactions range from mutualism, in which bothorganisms benefit, to parasitism, where one organism benefits at the expense ofthe other. Horizontal gene transfer is the acquisition of genes independent ofvertical transmission and demonstrably promotes the transition of bacteria...

Histological comparisons of needle tissues of four species of white pine infected by Cronartium ribicola

Creator:: Sweeney, Katarina
Abstract:: Hypersensitive response-like (HR-like) needle reactions to infection by the white pine blister rust pathogen, Cronartium ribicola, have been reported for several species of five needle pines native to western North America. The best-studied examples are in Pinus monticola and P. lambertiana. In these species a "needle spot" phenotype has been...

Effects of season and interval of prescribed burns on pyrogenic carbon cycling in ponderosa pine stands in Malheur National Forest

Creator:: Matosziuk, Lauren
Abstract:: In ponderosa pine (Pinus ponderosa) forests of the western United States, prescribed fires are used to reduce fuel loads and restore historical fire regimes. The season in which prescribed burns are performed and the interval between burns can have complex consequences for the ecosystem, including soil carbon cycling through the...

Response of Soil Temperature, Moisture, and Respiration Two Years Following Intensive Organic Matter and Compaction Manipulations in Oregon Cascade Forests

Creator:: Gallo, Adrian Carlos
Abstract:: Forest soils contain a substantial portion of global terrestrial carbon stores. Forest management can influence the soil carbon pool and how soil organic matter functions. The long-term productivity of forests is an ongoing goal where land managers utilize biomass and timber. A site-specific understanding of intensively managed forests can ensure...

Analytical determination of copper speciation in Oregon highway runoff

Creator:: Sprick, Matthew S.
Abstract:: Low concentrations of dissolved copper have been shown to adversely affect the olfactory system of endangered salmonids, impairing their ability to avoid predators and likely increasing predation. It is believed that only the free ionic (Cu2+ free) and weakly complexed forms are bioavailable to organisms; these forms typically account for...

Effect of intervention strategies on specific verbal feedback of volunteers and its secondary effect on qualitative motor performance

Creator:: Gately, Jeanne E.
Abstract:: The purpose of this study was twofold. First, to determine if planned interventions could increase untrained undergraduate students' use of positive and specific skill feedback while a teaching fundamental motor skill to children who are disabled. Second, to qualitatively assess the effect of specific verbal feedback on student motor performance....
