Magnetotellurics is used in two geologic settings on scales ranging from 1000-km tectonic structures to local features hundreds of meters wide. These areas are the Midcontinent Rift System (MRS) and its related mantle plume in the northern Midwestern United States and Newberry Volcano in central Oregon.
The MRS study uses...
The contamination of ground water resources represents a serious
problem and a prominent threat to the health of our society. This study
focuses on the leaching of inorganic anions as a function of agricultural
practices under natural field conditions. In order to enhance the
understanding of such leaching processes, this...
An accurate state estimation plays an essential role in power system operation and planning in energy management systems. However, existing multi-area state estimation researches have not focused on the importance of system clustering. The clustering mechanism divides or partitions a system according to user-defined criteria. Few published research works have...
This thesis analyzes the relationship between whiteness, womanhood, and the profession of student affairs using the method of autoethnography and the guiding question: How does my personal understanding of white womanhood affect my work and role as a student affairs practitioner? The researcher identifies three goals at the beginning of...

With the miniaturization of microelectronics and increase of processor speeds in the last few decades, thermal management is drastically affecting overall packaging and system capabilities. Due to the special needs introduced, research focusing on microscale cooling has increased. This study combines the positive characteristics of single- and two-phase flows in...
This thesis explores the experiences of ten asexual and aromantic college students at Oregon State University and the strategies they used to navigate their sexualized and romanticized campuses. The questions that guided this research were about belonging, resilience, kinship, and worldview. Did they feel they belonged to anyone or mattered...
It is hypothesized that increases in pressure drop due to vapor generation during boiling in microchannels can be reduced by extraction of vapor at its point of inception. Ultimately, this local vapor extraction decreases the pressure drop required to drive the flow through a fractal-like branching, microchannel flow network within...
Amines formed by biosynthesis in germinated barley have been
suggested as precursors for N-nitrosodimethylamine (NDMA) in barley
malt dried by direct-fired kilning. This hypothesis was verified by
germinating raw barley and exposing the resulting malt roots and
clean malt to nitrous acid. Quantitation of the NDMA formed indicated
that malt...
Four key aspects of the relationship between predatory hoverflies and the aphid pest Brevicoryne brassicae L. on broccoli were investigated in the Willamette Valley, Oregon USA: 1) the relationship between aphid density and hoverfly oviposition, 2) the larval voracity of key hoverfly species, 3) the preferences of hoverflies and broccoli...
