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...
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...
A recombinant inbred line (RIL) mapping population developed from a cross between winter wheat (Triticum aestivum L.)
cultivars Coda and Brundage was evaluated for reaction to stripe rust (caused by Puccinia striiformis f. sp. tritici). Two
hundred and sixty eight RIL from the population were evaluated in replicated field trials...

Cytokinins are a group of plant hormones mediating cell division and
differentiation. Zeatin is a naturally occurring and highly active cytokinin that is rapidly
metabolized in Phaseolus seeds. The metabolites and enzymes mediating the conversion
have been studied extensively. Zeatin metabolic enzymes may be utilized in studying the
regulation of...
In the United States, rates of youth vaping are alarmingly high. In 2018, the U.S Surgeon General declared youth vaping as an epidemic (Truth Initiative, 2019a). However, LGBTQ+ youth are disproportionately affected. In 2017, current e-cigarette usage in youth was 13.2% among heterosexuals, but was 17.5% in LGBTQ+ youth (CDC,...
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...
Two studies were initiated in June of 1981 in order to gain greater understanding of the growth and fruiting habits of field grown strawberries in Oregon's Willamette Valley.
Yield component analysis of 'Benton', Oregon's leading cultivar and an advanced breeding selection, 'OR-US 4356' was conducted during the first (1981) and...
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...
