Addressing the relationship between Pseudoperonospora cubensis and P. humuli using phylogenetic analyses and host specificity assays

Creator:: Mitchell, Melanie N.
Abstract:: The two most economically important plant pathogens in the Pseudoperonospora (Peronosporaceae) genus are P. cubensis, causal agent of cucurbit downy mildew, and P. humuli, causal agent of hop downy mildew. These organisms have been shown to be very closely related phylogenetically and morphologically. In 2005, researchers in Korea proposed that...

Physical factors affecting the spatial distribution of infaunal bivalve assemblages and species along the continental shelf of the Pacific Northwest

Creator:: Labou, Stephanie Grace
Abstract:: The spatial distribution and abundance patterns of benthic infauna result from interactions with a host of environmental variables including sediment characteristics (percent silt-clay, grain size, total organic carbon), depth, temperature, and dissolved oxygen. This thesis focuses on the association of bivalve assemblages and species with potentially influential environmental variables along...

Using parasite community data and population genetics for assessing Pacific sardine (Sardinops sagax) population structure along the west coast of North America

Creator:: Baldwin, Rebecca E. B.
Abstract:: Pacific sardines (Sardinops sagax) are an economically and ecologically important forage fish which transfer energy from planktonic primary producers and secondary consumers to upper trophic predators. Previous genetics studies of Pacific sardine suggested a panmictic population with a shallow genetic structure. However, more than one subpopulation within the Central California...

Effect of pharmaceuticals and natural products on multidrug resistance mediatedtransport in Caco-2 and MDCKII-MDR1 drug transport models

Creator:: Fan, Ying
Abstract:: This thesis details my investigation of some pharmaceuticals and natural products on the transport of drugs which are substrates of P-glycoprotein (P-gp), such as cyclosporin A (CSA) and digoxin by using Caco-2 and MDCKII-MDR1 drug transport models. Three objectives were performed to address this goal. The first objective was to...

Normal acceleration characteristics of the leading vehicle in a queue at signalized intersections on arterial streets

Creator:: Zhu, Hong
Abstract:: Normal acceleration characteristics of passenger cars provide valuable information for various aspects of transportation engineering, including use in the geometric designs of intersections, freeway ramps, passing lanes, acceleration lanes, turning bays, or in the development of traffic simulation or fuel consumption models. However, the data used in previous studies are...

Using Oregon trawl logbooks to study spatial and temporal characteristics of commercial groundfish species associations

Creator:: Lee, Yong Woo
Abstract:: Species associations of fifteen major commercial groundfish species in the northeastern Pacific ocean and their spatial and temporal characteristics were studied using Oregon bottom trawl logbook data, 1987 to 1993. Screening procedures were used to remove questionable data from the original logbook files, which resulted in the exclusion of information...

Spawning, larval recruitment, and early life survival of Pacific lampreys in the South Fork Coquille River, Oregon

Creator:: Brumo, Abel F.
Abstract:: Recently, there has been concern over the decline of the Pacific lamprey, Lampetra tridentata, in the northwestern United States. However, effective management has been impeded by data gaps in basic biology, especially in the early life stages. Consequently, in 2004 and 2005 I examined reproductive ecology, larval recruitment, and lamprey...

Grazer-resource Behavior, Interactions, and Feedbacks Control Kelp-forest Dynamics and Stability

Creator:: Randell, Zachary H.
Abstract:: How the direct and indirect effects of species interactions cascade to affect community structure, functioning, and stability is a fundamental question in ecology. In temperate kelp forests, species interactions, in conjunction with environmental processes, produce rich spatiotemporal dynamics. Arguably the most dramatic of these are abrupt shifts in community state,...

Molecular fingerprinting, rDNA internal transcribed spacer sequence, and karyotype analysis of Ustilago hordei and related smut fungi

Creator:: Abdennadher, Mourad
Abstract:: Inbreeding of the avirulent physiologic race 8 strains of Ustilago hordei was purported to have increased its pathogenicity in a stepwise manner that led to a highly pathogenic race, designated race 14. The analysis of electrophoretic karyotypes and restriction fragment length polymorphism profiles detected with a telomere-specific probe (TelomereRFLP) in...

A novel self-sealing chewable sustained release tablet of acetaminophen ; Development and evaluation of novel itraconazole oral formulations ; A novel zero order release matrix tablet

Creator:: Rakkanka, Vipaporn
Abstract:: This thesis describes evaluation of a novel self-sealing chewable sustained release tablet that can maintain controlled release of drug regardless of compaction, crushing, or chewing. The new formulation contains polyethylene oxide which produces a sealant effect for cracks produced in the polymer coating during compaction. Dissolution studies were conducted and...
