Improving part load efficiency of screw air compressors

Creator:: Maxwell, Jonathan B.
Abstract:: Air compressor systems are inefficient energy transfer devices even under the best of conditions, at full load. When only part load is required, efficiency drops further. This thesis attempts to improve part load efficiency of twin rotor screw air compressors in three ways. First, a guidebook was written to help...

Water movement in the stem xylem in relation to xylem specific conductivity in four hardwood species

Creator:: Fallas-Cedeño, Lottie
Abstract:: In deciduous species, water exits stems mainly through leaf traces attached to the outer growth ring and yet we know that water ascends throughout the entire cross-section of the sapwood. There is an increasing amount of information on sap flow and sapwood hydraulic properties from separate studies, but little information...

Impact of tropical instability waves on nutrient and chlorophyll distributions in the equatorial Pacific

Creator:: Evans, William Wiley
Abstract:: Tropical instability waves (TIWs) are prominent seasonal features in both the equatorial Pacific and Atlantic Oceans. This work quantifies their role in modulating the distributions of nutrients and phytoplankton biomass. Using an eight year record of biannual ship observations along the Tropical Atmosphere Ocean (TAO) buoy array, cruise sections crossing...

Analysis of carbon dioxide levels in a mechanically ventilated college classroom

Creator:: Silva, Andrew P.
Abstract:: Poor air quality can result in reduced productivity and higher absenteeism in students, fatigue, eye, nose and throat irritation and reduced comfort. The Occupational Safety and Health Administration (OSHA) estimates that 2 million education employees work in areas with poor indoor air quality. The measurement of carbon dioxide often is...

The teacher efficacy of early career agriculture teachers in five western states

Creator:: McKim, Aaron J.
Abstract:: The purpose of this study was to investigate the relationships between three teacher development experiences and early career agriculture teachers' efficacy. Additionally this study sought to define the relationship between five teacher efficacy constructs and career commitment among early career agriculture teachers in five western states. A census of all...

Overexpression of the GROWTH REGULATING FACTOR 4-GRF-INTERACTING FACTOR 1 Transcription Factor Chimera Modifies Transformation and Regeneration Efficiency in Populus and Eucalyptus

Creator:: Ryan, Nathaniel W.
Abstract:: Transformation is a major bottleneck for genetic engineering and gene editing in forest tree species. This includes most genotypes of Populus and Eucalyptus, which are some of the world’s most widely-cultivated genera of plantation forest trees. To provide new tools for transformation, I tested the transcription factor-protein chimera consisting of...

Brown on the inside : multiracial individuals and white privilege

Creator:: Quihuiz, Shannon D.
Abstract:: Biracial and Multiracial people are one of the fastest growing racial groups in the United States. Individuals with a mixed identity have the ability to choose endless racial/ethnic designations that best exemplify their racial/ethnic social identity. However, people who are racially/ethnically mixed may receive criticism if their proclaimed identity does...

Seasonal estimates of nitrogen fixation by Alnus rubra and Ceanothus species in western Oregon forest ecosystems

Creator:: Kim, Dong Yeob
Abstract:: Two case studies of 5 ecosystems were used to examine the nitrogen fixation rate of red alder (Alnus rubra Bong.), varnishleaf (Ceanothus velutinus var. laevigatus (Hook.) T. & G.), deerbrush (C. i ntegerrimus H. & A.), and snowbrush (C. velutinus var. velutinus Dougl. Ex Hook). The first case study assayed...

Utilizing cooperative fisheries research to monitor and understand harmful algal blooms along the Oregon coast

Creator:: Gilliland, Raquel C.
Abstract:: Harmful algal blooms (HABs) are a problem for coastal communities, the fishing industry, and coastal organisms. Pseudo-nitzschia spp. is a regularly occurring diatom in Oregon’s coastal waters. At times, Pseudo-nitzschia spp. can facultatively produce domoic acid, a neurotoxin that can bioaccumulate in the food chain. While regular shore-based sampling provides...
