Effects of Subsampling Trees and Imputation Methods on the Accuracy of Height-to-Crown-Base Predictions for Douglas-fir in Southwest Oregon

Creator:: Allensworth, Elijah J.
Abstract:: Accurate estimates of height-to-crown-base (HTCB) are essential for the reliable projections of stand structure over time required for sustainable forest management. Yet, HTCB often measured alongside total height (HT) for only for a subsample of trees in traditional stand-based inventories and must be imputed for all others. We compared the...

Check Characterization in Maple Plywood

Creator:: Wilson, Elijah J.
Abstract:: Small hairline cracks called checks in the decorative face veneer of hardwood plywood are a costly problem for the hardwood plywood industry. Hardwood plywood describes any plywood sheet with a hardwood face veneer glued onto a core substrate. Checks form due to differential shrinkage stresses. Not all hardwood plywood panels...

Class Number One Problems

Creator:: Bunnell, Elijah
Abstract:: In this paper we examine some of the developments concerning the Gauss class number problems and build a solid understanding of the class number. First we will develop some background knowledge necessary to understand the problem, specifically the theory of quadratic forms and quadratic fields and how the class number...

Compulsory Sexuality and Amatonormativity in Higher Education : A Photovoice Study with Asexual and Aromantic Students

Creator:: Stucki, Elijah G.
Abstract:: This thesis explores the experiences of ten asexual and aromantic college students at Oregon State University and the strategies they used to navigate their sexualized and romanticized campuses. The questions that guided this research were about belonging, resilience, kinship, and worldview. Did they feel they belonged to anyone or mattered...

The effects of tillage and irrigation on sweet corn (Zea mays L.) development, yield, and water use

Creator:: Petersen, Kerry L.
Abstract:: 'Jubilee' sweet corn was grown under conventional tillage and strip tillage in 1982 and under conventional tillage, strip tillage and no-till culture in 1983. Effects on soil temperature, stand establishment, plant development parameters, overall yield, yield components, and water use efficiency were measured. In 1982, conventional tillage appeared to have...

A vector electrocardioscope system for clinical studies

Creator:: Petersen, Walter Anton
Abstract:: This paper discussed the human electrocardiogram, the instrumentation used to graphically record it, and the design and performance of a specialized system for vector cardiography: the Vector Electrocardioscope (VECS) System. The introduction reviews in considerable detail the pertinent known physiology of the heart, especially the electrophysiology responsible for the genesis...

Density Functional Theory Investigation of CH Coupling and CH Hydrogenation Reactions on Different Cobalt Surface Facets and Fischer-Tropsch Temperature Swing Reactor Optimization

Creator:: Petersen, Dennis F.
Abstract:: Fischer-Tropsh Synthesis is a chemical process that converts CO and H₂ (syngas) into long stable hydrocarbon chains to use as fuel. This process suffers from large product distribution that requires expensive post processing. In this study, the reaction mechanism of hydrocarbon chain growth on Co is investigated on different surface...

Linking greater sage-grouse habitat use and suitability across spatiotemporal scales in central Oregon

Creator:: Freese, Mark T.
Abstract:: Greater Sage-grouse (Centrocercus urophasianus) habitat research has historically focused on fine-scale (0.007 - 0.032 ha) vegetation structure and composition immediately surrounding sites selected by birds. However, little work has evaluated vegetation attributes important for Greater Sage-grouse at a landscape-scale or identified landscape attributes that influence habitat use patterns. Habitat use...
