Integrating solute transport, metabolism and processing in stream ecosystems

Creator:: González Pinzón, Ricardo A.
Abstract:: After three decades of active research coupling hydrology and stream ecology, the connection among solute transport, metabolism and processing is still unresolved. These knowledge gaps obscure the functioning of stream ecosystems and how those ecosystems interact with other landscape processes. We must resolve these challenges to wisely manage water resources,...

Experimental Investigations of the Unsteady Aerodynamics of Oscillating Airfoils Operating in the Energy Harvesting Regime

Creator:: Siala, Firas F.
Abstract:: The rising global trend to reduce dependence on fossil fuels has provided significant motivation toward the development of alternative energy conversion methods and new technologies to improve their efficiency. Recently, oscillating energy harvesters have shown promise as highly efficient and scalable turbines, which can be implemented in areas where traditional...

The Impact of Disturbance on Carbon Stores and Dynamics in Forests of Coastal Alaska

Creator:: Yatskov, Mikhail A.
Abstract:: Changes in climate caused by increased concentrations of carbon dioxide (CO₂) in the Earth’s atmosphere have led land and ocean surface temperatures to increase by 0.85°C and sea level to increase by 19 cm relative to preindustrial times. Global climate change will lead to further alterations in mean temperature and...

Chronic exposure of rodents to indole-3-carbinol and 3,3'-diindolylmethane : implications for drug metabolism, chemoprevention and human health

Creator:: Leibelt, Dustin A.
Abstract:: Indole-3-carbinol (I3C) is a naturally occurring plant alkaloid, found in significant concentrations in cruciferous vegetables such as broccoli and Brussels sprouts. I3C is an unstable compound that undergoes rapid oligomerization in an acidic environment to form higher order condensation products (I3C-ACPs), such as 3-3'-diindolylmethane (DIM). Both I3C and DIM are...

Using stable isotopes and visual gut examination to determine the diet composition of Pterostichus melanarius (Coleoptera: Carabidae) in western Oregon vegetable row crops

Creator:: Moulton, Laurel A.
Abstract:: The omnivorous ground beetle, Pterostichus melanarius Illager (Coleoptera: Carabidae), is a ubiquitous inhabitant of western Oregon crop land. Because it is often the most abundant ground beetle, and attains densities that could lead to serious impacts on its prey sources, I sought to understand the overall diet composition, and specifically...

Deep Perception Without a Camera: Enabling 3D Reconstruction and Object Recognition using Lidar and Sonar Sensing

Creator:: DeBortoli, Robert A.
Abstract:: Deep learning has recently revolutionized robot perception in many canonical robotic applications, such as autonomous driving. However, a similar transformation has yet to occur in more harsh environments including underwater and underground. This is due in part to the difficulty in deploying robots in these environments, which lack large real...

Deep learning for robotic exploration

Creator:: Caley, Jeffrey A.
Abstract:: Emerging applications for robotic data collection include ocean monitoring, emergency response and urban search and rescue. At the core of these applications is a robot's ability to make informed decisions on incomplete data. This dissertation addresses this problem by developing novel techniques for modeling and estimating structured environments using deep...

Applications of Holographic Optical Tweezers: Multiplexed Fluorescence Spectroscopy and the Micromechanics of Type-I Collagen

Creator:: Cibula, Matthew A.
Abstract:: The development and some applications of holographic optical tweezers (HOT) are presented. Our HOT system uses a spatial light modulator (SLM) to control the location and properties of the optical trap. We have developed a method for optimizing the diffraction efficiency of a SLM that can be applied in situ...

Critical factors affecting the meaningful assessment of student learning outcomes : A Delphi study of the opinions of community college personnel

Creator:: Somerville, Jerry A.
Abstract:: The two-fold purpose of this study was to identify critically important factors that affect the meaningful assessment of student learning outcomes and study why they were critically important. A three-round Delphi process was used in both a pilot project and in a full study to solicit the opinions of individuals...

Is Your Community College Technology Ready? An Assessment Instrument to Promote Technology Adoption

Creator:: Boehme, Laura A.
Abstract:: Background: Calls by presidents and legislators to raise the U.S. college graduation rate to 60% by 2025 have required educational institutions to find ways to increase accessibility and quality while simultaneously reducing costs (Bautsch, 2018; Smith, 2017). Private foundations such as the Bill and Melinda Gates Foundation are getting involved...
