The frequency of devastating disasters has increased in the United States due to the presence of climate change. Human subject research is often conducted in these post-disaster areas to gain valuable data and insights. In recent years, discourse regarding the ethical nature of research conduct in these exposure areas has...
Ocean Drifters are a low-cost and easy-to-use platform that are commonly used for studying ocean currents. With added interest in studying the ocean, emphasis has been taken to make it more accessible. A pilot course focused on introducing the topic of ocean sensing was announced. The HC 407 course will...
Small, private forestland owners own about 12% of Oregon’s forestland and have the unique ability to implement innovative forest management activities. In southwest Oregon, extreme ecological variability occurs over small spatial scales and requires fine-scale silvicultural treatments that match the precise ecological setting and management objectives of the forests in...
Mathematics outreach typically consists of community events that show the exciting applications of mathematics, particularly to K-12 students. The goal of mathematics outreach events is to increase student interest and involvement in mathematics-related activities. Students start to develop a stigma against mathematics by the end of elementary school. Outreach events...
Recent advances in robotics have led to interest in exploring soft robotic technologies as an engineering control for reducing the risk of radiation exposure for workers in the nuclear industry. These emerging “soft” technologies offer many advantages over traditional rigid robotic systems and can perform a wide range of tasks...
To investigate the viability of staging hydraulic air compressors (HACs), a model for HACs operating with a closed loop water cycle powered by a pump was made. This model was used to simulate how these HACs would respond to variable heights and mass flow ratios for both single-stage and multi-stage...
This thesis is in two sections. The first is, "Truths: Memoir & Poetry," and the second, “Larger Truths: Fiction & Poetry.” The entire thesis is drawn from my experiences in America as a Black woman. "Truths" contains the beginning of a memoir about growing up with a domineering matriarch, and...
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:...

This thesis explores the mechanical properties of hemp fiber reinforced polylactic acid (PLA) composites. Fused filament fabrication (FFF) was used to compare the performance of three different weight percentages of hemp fiber reinforced PLA against PLA and acrylonitrile butadiene styrene (ABS). It was found that as the weight percentage of...
