X-ray computed tomography is a noninvasive imaging modality capable of reconstructing exact density values of 3D objects. Computed tomography machines are deployed across the world to provide doctors with an image that reveals more detail than a standard x-ray image. We investigate algorithms based on exact computed tomography reconstruction formulas...
The relative enrichment of skin sebaceous gland lipids with deuterium-labeled α-tocopherol was compared with plasma enrichment to evaluate the delivery of vitamin E to skin. For the first week of this study, each subject consumed a daily dose of deuterated vitamin E (150 mg of an equimolar mixture of RRR-α-[5-(C²H₃)]-(d₃)...
The marine climate of the Galapagos is spatially and seasonally
heterogeneous. A taxonomically comprehensive study of Galapagos zooplankton has
never been done. This study is an initial effort to establish the distribution and
community structure of zooplankton in the Archipelago. I collected zooplankton
samples by vertical tows over the Galapagos...
The primary objective of this thesis is to develop a process for fabricating integrated circuits based on thin-film transistors (TFTs) using zinc tin oxide (ZTO) as the channel layer. ZTO, in contrast to indium- or gallium-based amorphous oxide semiconductors (AOS), is perceived to be a more commercially viable AOS choice...
Zinc tin oxide (ZTO) films deposited by pulsed laser deposition (PLD) are
investigated as a channel layers for transparent thin-film transistors (TTFTs).
Films are deposited on glass for characterization, and transistor channel layers are
deposited onto aluminum oxide-titanium oxide/tin doped indium oxide/glass
substrates (ATO/ITO/glass) to produce TTFTs.
UV-visible spectroscopy on...
Acquired Immune Deficiency Syndrome (AIDS) has become the world's foremost health threat and is the number one killer in Zimbabwe. Acquired Immune Deficiency Syndrome impacts not only the individual who has AIDS, but on nuclear and extended families, and all aspects of society in Zimbabwe. Since studies have indicated that...
A zeolite packed biofilter was retrofitted to a confined swine feeding operation in Eastern Washington, and evaluated for its ability to reduce the malodors from fan exhaust drawn from an internal under-slat manure storage pit. Ammonia (NH₃) was used as the representative constituent of swine waste malodor due to its...
Today in the United States, herbal supplements are growing increasingly popular, however, little is known about the safety and efficacy of these products. This study contributes to the growing body of information about the prevalence of herbal supplement use among young adults (18 to 24 years) and the beliefs young...
You Stay Here is the beginning of a novel that centers on the notion of family, community, and the expectations that drive our interactions within these circles. The novel tells the story of brothers Mills and Nance O'Malley as they interact with their parents, Richard and Margaret. The brothers own...
The sagebrush steppe ecosystem of the northern Great Basin is severely degraded and continues to decline due in large part to the invasive, non-native annual grasses Bromus tectorum L. (cheatgrass) and Taeniatherum caput-medusae (L.) Nevski (medusahead). Restoration of invasive-dominated areas is difficult, but can be enhanced by adding a carbon...
Yeast mannoproteins released during the process of aging wine on the yeast lees have been reported to make important contributions to wine quality. However, few mannoproteins have been identified in wine and their lifespan during aging is unknown. As a first step towards better understanding the contributions of yeast mannoproteins...
Reported here is an investigation to determine the in vitro and in vivo metabolism
of xanthohumol (XN). XN is the major prenylated flavonoid of the female
inflorescences (cones) of the hop plant (Humulus lupulus). It is also a constituent of
beer, the major dietary source of prenylated flavonoids. Recent studies...
We have performed fluorescence extended X-ray absorption fine structure (EXAFS) measurements on the Cd K-edge of partial electrolyte (PE) treated Cu(In[subscript 0.7]Ga[subscript 0.3])Se₂ (CIGS) thin film samples using synchrotron X-ray radiation. This data was compared to the EXAFS spectra of CdSe and CdO standards. Cd local structure models were constructed...
Doris Lessing and Tsitsi Dangarembga write fiction set in Zimbabwe, the former Southern Rhodesia. Although Lessing grew up as a white settler and Dangarembga, a generation later, as part of the colonized African population, the women sometimes address similar issues. Both write of young girls trying to find a speaking...
This collection of personal essays, inspired by Richard Rodriguez's Hunger of Memory, raises questions about the separation that becomes apparent through writing, education, and transitions between class. The author uses her personal experience of writing in, and attending a private university to explore the interactions of class, literacy, and education....
Kate Chopin, author of the proto-feminist novel The Awakening, was also a prolific writer of short stories. Nineteen of her stories were originally published in Vogue magazine between 1893 and 1900. This study looks at six of these stories, "The Father of Desiree's Baby," "A Respectable Woman," "The Dream of...
The purpose of this study was to explore wedding dress styles represented in United States high fashion magazines during the World War II period. The objectives of the study were to: discover what wedding dress styles were proposed by high fashion magazines during the period 1935-45, determine if wedding dress...
The purpose of this study was to identify and describe the underlying mechanisms within community colleges that influence cross-functional collaboration. The study also explored the role of community college leadership in fostering internal collaboration. The following questions guided the research: (1) What does cross-functional collaboration look like at a community...
My thesis explains the several problems that arise when a person from a Western English speaking country goes to work as an English teacher at private institutes in South Korea. It is based on my own experiences when I worked as an English teacher at private institutes in South Korea...
With the arrival of European settlers to Western Oregon nearly 150 years ago came new methods of forest management. Early settlers' forest practices consisted of little more than harvesting what seemed an endless supply of timber. Forestry in the 20th century eventually incorporated such management concerns as re-forestation, biodiversity, wildlife...
