Growth and characterization of zinc ferrite thin films for high frequency applications

Creator:: Hu, Jiqing
Abstract:: Ferrites have been used for various high frequency applications as bulk materials. These applications, however, are limited to large dimension devices. In this thesis, thin film ferrites were deposited from a low temperature solution-based deposition process that is suitable for micro-scale high frequency applications. The low temperature nature of this...

Quantities of prostaglandins in whole and extended bovine semen and their potential effect on fertility following insemination

Creator:: Jaeger, John Ralph
Abstract:: Our objectives were to determine 1) the concentration of prostaglandin F2α (PGF2α) in whole and extended bovine semen, 2) if concentrations of prostaglandins in extended bovine semen are correlated to fertility, and 3) if PGF2α administered at the time of artificial insemination would improve conception rate. Concentration of PGF2α tended...

Enhancing community college revenue sources by leveraging land resources

Creator:: Scott, Cheryl L.
Abstract:: Community colleges are experiencing a decline in state allocated funding. Traditionally, college administrators look for ways to cut expenditures and raise tuition and fees to make up for the shortfall. Using available land resources to generate a revenue stream may provide revenue for community colleges. The purpose of this study...

Expression and Function of Populus Homologs to TERMINAL FLOWER 1 Genes: Roles in Onset of Flowering and Shoot Phenology

Creator:: Mohamed, Rozi
Abstract:: We isolated and characterized the expression of two genes from Populus trichocarpa that are homologous to the TERMINAL FLOWER 1 (TFL1) gene from the model annual plant Arabidopsis. In Arabidopsis, overexpression of the TFL1 gene extends the vegetative growth phase, and the homozygous mutant tfl1 allele causes early flowering and...

Structure elucidation of bioactive natural products from Madagascar marine algae and cyanobacteria

Creator:: Andrianasolo, Eric Hajaniriana
Abstract:: This thesis is an investigation of the natural products deriving from marine algae and cyanobacteria and has resulted in the discovery of eleven new secondary metabolites. The structure elucidations of these new molecules were performed using a variety of spectroscopic techniques. Four new macrolides were isolated and characterized from the...

Heavy fermion effective mass in the superconducting vortex state

Creator:: Townsend, Emily A.
Abstract:: The extended-Lifshitz-Kosevitch formalism (ELK) unifies the treatment of the de Haas-van Alphen (dHvA) effect, allowing it to transcend its traditional roles of mapping Fermi surfaces and measuring effective masses. Here we exploit the capabilities of dHvA as a probe of many-body effects to examine heavy-fermion su- perconductivity. ELK successfully describes...

Biogeographic and experimental evidence for local scale dispersal limitation in central Panamanian forest birds

Creator:: Moore, Randall Phillips, 1965-
Abstract:: I examined the avian biogeography of the islands of Lago Gatun, Panama, in an effort to better understand the effects of forest fragmentation in this biodiverse region, and specifically to understand the importance of fragment isolation and the mechanism behind its effects on tropical bird distribution. I combined exhaustive surveys...

Spatial and temporal scales of genetic change in two overfished rockfishes

Creator:: Gomez-Uchida, Daniel
Abstract:: Pacific rockfishes (genus Sebastes) have attracted wide scientific and public interest from an evolutionary, fishery and conservation standpoints. This dissertation addresses several hypotheses involving spatial and temporal scales of genetic change in two overfished rockfishes, darkblotched (S. crameri) and canary rockfish (S. pinniger), using statistical analyses of genetic variation within...

Comparative foraging ecology of five species of Pacific seabirds : multi-scale analyses of marine habitat use

Creator:: Suryan, Robert
Abstract:: Seabirds are an integral component of marine ecosystems, however, because humans typically observe only snapshots of their lives at sea, our understanding of seabird foraging ecology is often limited. A more complete understanding of the ecological roles of seabirds and identification of critical foraging habitats requires the ability to follow...

The relationships between fluctuations in oceanographic conditions, forage fishes, predatory fishes, predator food habits, and juvenile salmonid marine survival off the Columbia River

Creator:: Emmett, Robert L.
Abstract:: Salmonid run sizes are strongly affected by their early marine stage. Fully understanding the life history of salmonids means understanding how they interact with their marine environment and with other fishes. Changes in the biological and physical environment off the Columbia River region affects the distribution and abundance of predatory...
