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...

Ghost factors of laboratory carbonate chemistry are haunting our experiments

Creator:: Galloway, A. W. E., von Dassow, G., Schram, J. B., Klinger, T., Hill, T. M., Lowe, A. T., Chan, F., Yoshioka, R. M., and Kroeker, K. J.
Abstract:: For many historical and contemporary experimental studies in marine biology, seawater carbonate chemistry remains a ghost factor, an uncontrolled, unmeasured, and often dynamic variable affecting experimental organisms or the treatments to which investigators subject them. We highlight how environmental variability, such as seasonal upwelling and biological respiration, drive variation in...

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...

Monitoring soil nitrate to estimate cover crop nitrogen contribution

Creator:: Andrews, Nicholas, Sullivan, Dan M., and Pool, Kristin
Abstract:: Organic vegetable growers rely on legume cover crops as an economical source of plant-available N. This research evaluated N contributions to summer vegetable crops by cover crops (CC) residues by monitoring soil nitrate (NO3-N) concentrations during the summer crop growing season. Replicated field plots were established with three CC mixes:...

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...

Assessing variation in coyote (Canis latrans) diet across three sagebrush steppe sites with different levels of juniper encroachment

Creator:: Kendall, Zachary D.
Abstract:: Juniper (Juniperus spp.) encroachment into the sagebrush steppe ecoregion is one of the main causes of sagebrush degradation and can alter the understory vegetative community by outcompeting native shrubs and grasses, which reduces the available forage and cover for small mammals. Coyotes (Canis latrans) are generalist, omnivorous predators in the...

Big fishery, big data, and little crabs: Using genomic methods to examine the seasonal recruitment patterns of early life stage Dungeness crab (Cancer magister) in the California Current Ecosystem

Creator:: Lee, Elizabeth M. J. and O'Malley, Kathleen G.
Abstract:: The California Current Ecosystem (CCE) is a dynamic marine ecosystem from which many socioeconomically important fisheries species are harvested. Here, a genotyping- by-sequencing (GBS) approach was used to examine genomic variation in an early life stage (megalopae) of the Dungeness crab (Cancer magister), which constitutes the most valuable single-species commercial...

Estimating option values and spillover damages for coastal protection : evidence from Oregon’s Planning Goal 18

Creator:: Dundas, Steven J. and Lewis, David J.
Abstract:: Estimating nonmarket benefits for erosion protection can help inform better decision making and policies for communities to adapt to climate change. We estimate private values for a coastal protection option in an empirical setting subject to irreversible loss from coastal erosion and a land-use policy that provides identifying variation in...
