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)...
What does comida rica mean? In this thesis, I explore the meanings of comida rica, sana, and de nuestra tierra through the discourses, practices, and kitchen geographies in six urban, highland households in the Ecuadorean Andes. This research, as part of a larger investigation carried out by a team of...
Site 35JA42 represents the first protohistoric village
complex excavated in Southwest Oregon. Analyses of animal
bones recovered from the site offer the first significant
insights into human subsistence behaviors in this region.
Although the faunal assemblage is extremely fragmented,
detailed zooarchaeological analysis indicates that deer were
the primary meat resource...
The effects of zinc and phosphorus treatments on five different
plant species were investigated in a greenhouse experiment. A
second greenhouse experiment extended these investigations in sweet
corn over a broad range of phosphorus treatments with and without
adequate zinc nutrition to study phosphorus induced zinc deficiency.
The plant responses...
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...
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...
The effects of some soil- and foliar-borne biotic factors on
grain yield and the components of yield were evaluated using five
winter wheat varieties sown at two dates. Within each planting date,
varieties were grown under four different combinations of two soil
treatments (fumigation and nonfumigation) and two foliar treatments...
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...
Yeast culture supplementation has been used to improve the health and performance of dairy cows for the last 25 years. To evaluate the effect of a Saccharomyces cerevisiae fermentation product (Diamond V Original XP™) on the health and production of peripartal Holstein cows, two research studies were conducted.
The first...
A brief history of X-ray control methods is presented, and
the instrumentation requirements and physiological considerations
pertaining to an automatic X-ray control system are discussed.
The latter half of the thesis describes the design and operation
of a device which will permit medical radiographs to be taken
automatically and at...
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...
This study focused on the worldminded attitudes of
Japanese college students in Japan and in the United States.
The effects of studying abroad and the change in attitudes
between Japanese college male students and female students
were examined in terms of worldmindedness, which is defined
as a frame of reference,...
Thirty-four current worksite health promotion programs were
studied in order to obtain comprehensive information about various components
involved in the planning, implementation, and evaluation of existing
programs, and to acquire the necessary data to develop a theory and corresponding
hypotheses pertaining to successful worksite health promotion
programs. The case study...
The purpose of this study was to monitor coronary responses
occurring in the S-T segment of an electrocardiogram before, during
and after exercise following a "standard" carbohydrate-loading schedule with varied vitamin B-6 supplementation. The study was conducted
using four college-aged males who had been training a minimum of two
years...
The present research sought to investigate the relationship between an individual's word choice and their social well-being. In the present investigation, social well-being is a person's social health in relation to their social environment, social network, and ability to interact with others in a social context. This thesis was based...
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...
In 1986, researchers from Oregon State University, led by Dr. David Brauner, came to the small Catholic community of St. Paul, Oregon as part of ongoing research on the French-Canadian inhabitants of the Willamette Valley between 1829 and the mid-1860s. They were searching for the remains of the first Catholic...
This research is based on in-depth interviews with 20 women farmers and
ranchers from the state of Oregon. These women employ a variety of methods and
subscribe to a number of divergent philosophies regarding agricultural practices.
The intention of this study is to examine how women who are the primary...
