The influence of induced host moisture stress on the growth and development of western spruce budworm and Armillaria ostoyae on grand fir seedlings

Creator:: Parks, Catherine G.
Abstract:: This greenhouse study evaluates the influence of separately and simultaneously imposed water stress, western spruce budworm (Choristorneura occidentalis Freeman) defoliation, and inoculation with the root pathogen, Armillaria ostoyae (Romagn.) Herink, on the growth and biochemical features of Abies .grandis (Dougl.) Lindi. Seedling biomass, plant moisture status, bud phenology, and allocation...

On the Structure of the Orbit Spaces of Almost Torus Manifolds with Non-negative Curvature

Creator:: Dong, Zheting
Abstract:: An almost torus manifold $M$ is a closed $(2n+1)$-dimensional orientable Riemannian manifold with an effective, isometric $n$-torus action such that the fixed point set $M^T$ is non-empty. Almost torus manifolds are analogues of torus manifolds in odd dimension and share many of the characteristics of torus manifolds. For example, both...

ALS-inhibitor resistant downy brome (Bromus tectorum L.) biotypes in Oregon : Mechanism of resistance, fitness, and competition

Creator:: Park, Kee-Woong
Abstract:: Understanding the mechanism of resistance, relative fitness and competitiveness of herbicide resistant biotypes is important to predict population dynamics and to establish resistance management strategies. This study was conducted to determine the level of resistance to acetolactate synthase (ALS) inhibitors and the mechanism of resistance of ALS-inhibitor resistant downy brome...

Assemblages and Adaptation: The Influence of Multispecies Social Networks on Small Farmers’ Perceptions of and Responses to Climate Change in Oregon

Creator:: Parks, Melissa
Abstract:: This study explores how multispecies social networks influence small farmers' perceptions of and responses to climate change across Oregon. Local food sovereignty and food system resilience depend on a robust local food system in which small farms play a critical role. To maintain their viability, small farmers must adapt to...

Spatial and inter-temporal price analysis : including risk perceptions and dynamic trade flow information

Creator:: Han, Shengfei
Abstract:: A regime-switching model for market integration study is extended to incorporate dynamic trade flow information and risk perceptions based on an expected utility framework. An application of the extended model to the US-China soybean markets analysis shows that: One, the positive arbitrage rent uncounted-for in the extended model has been...

A comparison of the effects between letter-grades and pass-fail grades on the attitudes and achievement of eleventh grade United States history students

Creator:: Pike, John Michaels
Abstract:: This study was designed to determine whether individual students at the eleventh grade level who were graded on a pass-fail basis in United States History would show any difference in academic achievement from those of a similar group marked by the traditional ABCD-F letter-grade method. In addition, the study was...

Probabilistic Tsunami Hazard and Damage Assessment of the Built Environment : Applied at Seaside, Oregon

Creator:: Park, Hyoungsu
Abstract:: Damage estimates to the built environment from tsunamis are important for disaster mitigation, including planning emergency response and recovery. This dissertation evaluates the damage states of buildings in a small urban coastal city, Seaside, Oregon, from tsunami hazards generated by a Cascadia Subduction Zone (CSZ) event. This study is separated...

Spatiotemporal Distributions of Bacteria in the Cheddar Production Environment

Creator:: Johnson, Jared D.
Abstract:: Given the many significant roles that bacteria play in modern food manufacturing, it is crucial that we have a fundamental understanding of how bacterial communities assemble and behave in the food manufacturing environment. The focus of this dissertation was to investigate both the spatial and temporal distributions of microbial communities...

Connections between combinatorics of permutations and algorithms and geometry

Creator:: Wills, Dean Connable
Abstract:: Geometric Problems become increasingly intractable and difficult to visualize as the number of dimensions increases beyond three. Inductions from lower dimensional spaces are possible yet often awkward. This thesis shows how elementary linear algebra, vector calculus, and combinatorics offer improved methods for calculating the dihedral angles of n-simplicies and proving...

Application of GNSS for Vertical Reference Determination

Creator:: Kim, Su-Kyung
Abstract:: Vertical datum is a reference system used for specifying the elevation of specific points on or near the Earth. Precise and accurate definition and realization of vertical references are, therefore, crucial to ensure consistency between height measurements. The vertical datums can be divided into two categories: 1) vertical geodetic datums...
