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 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...
The free-radical theory of aging proposes that intracellular accumulation of oxidative damage caused by
reactive oxygen species (ROS) is responsible for the process of senescence. ROS are produced during
normal aerobic metabolism and have been shown to cause numerous cellular and sub-cellular defects
that lead to termination of the cell...
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...
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...
In order to combine my passion for creativity, my love for children, and my engineering background, I decided to create a very personalized thesis project. Princess Catie Goes to College is a children’s book about a young girl whose older sister leaves for college. I chose to write about this...
This thesis consists of an autoethnography of a sexual assault survivor written using poems, journal entries, annotations, photographs and song lyrics. The ethnography is a chronological record of feelings the author experienced during the day prior to the attack and emotions she navigated during the year and a half after...
Creating an untraditional more personalized thesis allowed me to combine my
passion for children, travel, language, and books all into one. Hans the Adventurer is
a children’s book about a young German boy who loves to go on adventures.
However Han’s has to go on the adventure alone when his...
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...
Woody riparian vegetation is an essential component of riparian ecosystems, responsible in part for the maintenance of functional ecological processes. The plant community composition and distribution provide an indication of the underlying mosaic of environmental attributes and processes. Restoration and management of riparian communities have been hindered by the lack...
There are a number of wood properties which affect the quality of forest products such as lumber and pulp. Of these, wood density is considered by some to be the single most important physical characteristic because it is an excellent predictor of strength, stiffness, hardness, and paper-making capacities. Accurately assessing...
Light-frame construction practices and materials have changed greatly
over the past 100 years. Contemporary research has focused on modern construction; thus, we know a great deal about the behavior of modern lightframe buildings under lateral forces. However, there are many light-frame buildings that were built prior to the introduction of...
The perception of the self as a sexual being is challenged by the
experience of pregnancy. Included in the experience of pregnancy are
issues with perceptions of the self, body image, transition into
motherhood, and reconciliation of the self as a sexual being during
pregnancy. Through a review of the...
This study sought to conduct an in depth analysis of women’s first sexual experiences looking for factors contributing to the experience and the emotional outcomes of first intercourse. Fourteen heterosexual, female, college students were interviewed about their first sexual experience and sexual background using a semi-structured interview format. The narratives...
Women in Transition: The Mexican Family, Migration, and the Mothers of Casa de los Angeles is broken into three parts: methodology, history of migration and gender roles, and in Mexico, the examination of interviews from mothers in San Miguel de Allende. Methodology explores the various ways historian collect oral histories....
