A catchment-scale assessment of stream temperature response to contemporary forest harvesting in the Oregon Coast Range

Creator:: Kevin Bladon, Nicholas Cook, Jeffery Light, and Catalina Segura
Abstract:: Historical forest harvesting practices were reviewed in the original Alsea Watershed Study where they found increased energy loading to the stream and produced higher stream temperatures. This was an important early research site that led to the development of contemporary forest management practices to protect water quality and fish habitat...

Studying the ancient parasitic cnidarian, Sphaerospora elegans, leads to better understanding of oligochaete diversity and myxozoan discovery

Creator:: Lehrburger, David J.
Abstract:: Myxozoans are microscopic parasites, related to corals and jellyfish. Most Myxozoa probably have two-host lifecycles that require a vertebrate (typically fish) and invertebrate (annelid or bryozoan). However no life cycle is known from the Sphaerospora lineage. I hypothesized that the life cycle of Sphaerospora elegans, a myxozoan parasite of three-spined...

The Processing and Microstructures of 309L Stainless Steel Clad onto Carbon Steel with Wire-fed Directed Energy Deposition

Creator:: Bozeman, Scott C.
Abstract:: Directed energy deposition and laser cladding technologies are suitable advanced manufacturing techniques for applying corrosion-resistant claddings to large carbon steel components. In this work, we clad 309L stainless steel wire onto carbon steel substrates and examine the effects of cladding parameters (laser power and travel speed) on metallurgical bonding, composition,...

Performance of Brettanomyces Yeast Strains in Primary and Secondary Beer Fermentations

Creator:: Humbert, Riley
Abstract:: Recently, there has been an expansion of large-scale studies looking at strain variation of Brettanomyces. These studies have found variation between strains in terms of utilization of maltose and production of volatile phenols. While there is research going into this subject, there is a gap in knowledge regarding the differences...

An Analysis of Post-Medieval Ceramics from the Pendle Hill Witches Archaeological Excavation

Creator:: Connolly, Madeleine E.
Abstract:: This analysis seeks to (1) establish a typology of the post-medieval ceramics from the Malkin Tower site, (2) determine vessel forms and extrapolate site function, and (3) establish a tentative chronology for the site. Over four hundred post-medieval ceramic artifacts from the Malkin Tower site were analysed via descriptive and...

Alsea Watershed Study 1959-1972

Creator:: Souder, Jon
Abstract:: To investigate the effects of logging, three small watersheds in the Alsea River basin on the west slope of the Oregon Coast Range were selected for study. This was an interdisciplinary investigation to evaluate the influence of specific logging methods on stream regimen and on aquatic resources. The study plan...

Just a tool after all? No evidence for tool-use effects on the body representation across virtual and real environments

Creator:: Bell, Joshua D.
Abstract:: While human tool-use proficiency helped define our history, the cognitive and perceptual mechanics of how humans use tools are not fully understood. This question is of great value to the design of hand-held tools and prosthetics. A prominent theory, tool embodiment, suggests that tool use is facilitated by a flexible...

Organic Pelletized Chicken Manure Application Rates and Effects on Novel Asian Vegetables in the Willamette Valley

Creator:: Velazquez, Hannah D.
Abstract:: Daikon, mizuna, mizspoona, and komatsuna are novel Asian vegetables for which a market exists in Oregon, especially in the organic sector. However, these crops are currently not grown widely in the area, despite the favorable growing environment of Oregon’s Willamette Valley. Little is known about the appropriate application level of...

Real-time Speech Workload Estimation

Creator:: Fortune, Julian D.
Abstract:: Demanding task environments (e.g., supervising a remotely piloted aircraft) require performing tasks quickly and accurately; however, periods of low and high operator workload can decrease task performance. Intelligent modulation of the system’s demands and interaction modality in response to changes in operator workload state may increase performance by avoiding undesirable...

Assessment of the causal linkages between forests and fish: implications for management and monitoring.

Creator:: Martens, Kyle D.
Abstract:: Understanding the causal links between riparian forests, streams, and salmonids is important to help understand the likely effects of forest management practices. Previous studies have identified three major causal pathways (Instream Cover, Light, and Hydrology) through which riparian forests influence streams, and ultimately stream fishes. To evaluate the potential importance...

A Comparative Study of Non-Normal Distributions in Continuous Dropout

Creator:: Guyer, Alexander D.
Abstract:: Recent studies have shown that novel continuous dropout methods can be viewed as a Bayesian interpretation of model parameters, though most such studies have shown results using normal distributions. As the posterior distributions over neural network nodes and parameters are intractable, given that they are a result of artificial construction...

High resolution lake sediment record reveals self-organized criticality in erosion processes regulated by internal feedbacks

Creator:: Colombaroli, D., Gavin, D. G., Morey, A. E., and Thorndycraft, V. R.
Abstract:: Reconstruction of high-frequency erosion variability beyond the instrumental record requires well-dated, high-resolution proxies from sediment archives. We used computed tomography (CT) scans of finely laminated silt layers from a lake-sediment record in southwest Oregon to quantify the magnitude of natural landscape erosion events over the last 2000years in order to...
