Turnover, Memory, Persistence: Four Decades of Ecological Community at Lost Valley

Creator:: Bruno, Mark P.
Abstract:: This study is an ethnographic investigation of residential turnover, organizational memory, and the persistence of Lost Valley, an Oregon ecovillage founded in 1989. Literature on organizational turnover, memory, and persistence is reviewed and integrated with scholarship on intentional communities and ecovillages, generating a theoretical framework for data collection and analysis....

Parameter Estimation within a Kinematic Magnetohydrodynamics Framework

Creator:: Rajbhandari, Evan, Gibson, Nathan L., and Woodside, C. Rigel
Abstract:: We discuss the well-posedness of the forward problem for the magnetohydrodynamic system with the inclusion of the ion-slip parameter. We also demonstrate the convergence of a parameter estimation scheme. Focusing on power-generation, we implement and the validate a numerical model with an engineering multi-physics software, COMSOL, using ideal-power equations. We...

Quantifying uncertainty with stochastic collocation in the kinematic magentohydrodynamic framework

Creator:: Rajbhandari, Evan, Gibson, Nathan L., and Woodside, C. Rigel
Abstract:: We discuss an efficient numerical method for the uncertain kinematic magnetohydrodynamic system. We include aleatoric uncertainty in the parameters, and then describe a stochastic collocation method to handle this randomness. Numerical demonstrations of this method are discussed. We find that the shape of the parameter distributions affect not only the...

Stochastic Collocation Error Analysis Within a Kinematic Magnetohydrodynamics Framework

Creator:: Rajbhandari, Evan, Gibson, Nathan L., and Woodside, C. Rigel
Abstract:: We explore one numerical method for dealing with uncertainty quantification, stochastic collocation. We adapt this method for the uncertain kinematic magnetohydrodynamic system. We then demonstrate well-posedness of the uncertain forward problem. We also describe the method in detail, and perform an error analysis of the method, describing the necessary assumptions...

Bacteriophages Significantly Reduce Mortality of Larval Pacific Oysters Crassostrea gigas from Infection by the Pathogenic Bacterium Vibrio coralliilyticus RE98

Creator:: Madison, David B.
Abstract:: Vibrio coralliilyticus (Vcor) is a bacterial pathogen that is well adapted to shellfish hatcheries and is very pathogenic to the larvae of the Pacific oyster Crassostrea gigas. Vcor has been associated with several large scale larval mortality events in the Pacific Northwest that interrupt the supply of seed oysters available...

Mitigation Banks in Washington State: Case Study of Developing the Schold Farm Mitigation Bank

Creator:: Dadisman, Jennifer
Abstract:: Wetland habitats are disappearing at an alarming rate and research is finding that establishment and creation of wetland habitat is generally unsuccessful. Typical mitigation strategies in the past have created multiple small isolated wetlands with little functioning habitat. Within Washington State, guidance and research recommends utilizing mitigation banks to compensate...

Phenotyping Degeneration of the Intervertebral Disc with Principal Component Analysis and K-Means Clustering

Creator:: Chen, Joseph
Abstract:: The human intervertebral disc (IVD) provides support for the vertebral bodies, allowing for movement and load bearing. The IVD can degenerate with age or injury, impeding function and causing chronic pain. Despite disc degeneration affecting over 90% of adults over age 50, and back pain being the leading global cause...

Development of a Novel Device to Measure the Viscosity of High Temperature Molten Salts

Creator:: Blyther, Joshua D.
Abstract:: This thesis presents a novel design for a rheometer style viscometer by implementing high temperature and inert atmospheric requirements on the device. The goals of this device are to measure the viscosity of high temperature molten salts, which are corrosive and extremely hydroscopic. It also aims to be able to...

Looking for Fish of the Right Age : Developing Predictive Modeling for Submerged Sites Using GIS, Salmon Genetics, and the Human Ecology of Salmon

Creator:: Krier, Jon C.
Abstract:: A major challenge to the study of the peopling of the Americas is that much of the Bering Land Bridge (Beringia), the geographic area that people migrating from Northeast Asia into North America would presumably have passed through, is now submerged due to sea-level rise since the last glacial maximum....

An Interdisciplinary-Botanical Perspective for Cultural Resource Management: A Definition and the Application of Culturally Significant Plants in Identification, Interpretation, and Evaluation for the National Register of Historic Places

Creator:: Burk, Rene F.
Abstract:: Cultivated plants are often living artifacts that can aid in evaluation of historic or cultural landscapes. However, a working definition for “culturally significant plant” is currently lacking in the guidance literature for the cultural resource management practitioners. Based on a review of the literature on cultivated plants as indicators of...
