Genetic and phenotypic variation associated with the resistance gene SOD1 in Biomphalaria glabrata, an important intermediate host of Schistosomiasis

Creator:: Bonner, Kaitlin M.
Abstract:: Schistosomiasis afflicts 200 million people and is responsible for 200,000 deaths per year. The infection is caused by a digenean trematode in the genus Schistosoma. The parasite must cycle through both a vertebrate (human) and invertebrate (snail) host to complete the life cycle. My dissertation focuses on the genetic mechanisms...

Rearing density as a driver of adaptation to captivity and traits under selection by domestication in hatchery reared steelhead (Oncorhynchus mykiss)

Creator:: Thompson, Neil F.
Abstract:: Releasing hatchery reared salmon and steelhead to supplement threatened and endangered populations is a widely used conservation tool. One issue with this strategy is hatchery fish have lower reproductive fitness than wild fish when spawning in the wild. One of the drivers of fitness loss in steelhead is adaptation to...

Adaptive diversity and divergence at frog antimicrobial peptide loci

Creator:: Tennessen, Jacob A.
Abstract:: In this dissertation I study evolutionary patterns at genes encoding antimicrobial peptides (AMPs) in frogs. AMPs are short, amphipathic, cationic, secreted proteins that kill bacteria and other pathogens through a non-catalytic mechanism that involves binding to and disrupting the microbial cell membrane. In many animal taxa, positive selection is much...

Population genetics of ranid frogs : investigating effective population size and gene flow

Creator:: Phillipsen, Ivan C.
Abstract:: This dissertation focuses on the evolutionary forces of genetic drift and gene flow in frog populations. The balance of these two forces and the force of mutation largely determine the amount of neutral genetic variation within populations as well as the degree of genetic similarity among populations. The stochastic evolutionary...

Random dopants and low-frequency noise reduction in deep-submicron MOSFET technology

Creator:: Miller, Drake A.
Abstract:: The future of mixed-signal, memory, and microprocessor technologies are dependent on ever increasing analog and digital integration, higher cell densities, and demand for more processing power. As a result MOSFET device dimensions continue to shrink to meet these demands. A side effect of device scaling is increased variability at each...

Nitrogen use in container-grown woody ornamentals

Creator:: Sandrock, David Ray, 1971-
Abstract:: Lasting, effective solutions to nitrogen (N) loss from container nurseries must address layers of complexity ranging in scale from whole system nursery management to gene expression. Group-based On-site Active Learning (GOAL) was developed to aid nursery managers and related stakeholders (e.g. neighbors, policy makers, regulating agencies, researchers) in developing a...

Investigations of Black Leg and Light Leaf Spot on Brassicaceae Hosts in Oregon

Creator:: Claassen, Briana J.
Abstract:: The Pacific Northwest is an internationally important region for the production of Brassica seed and other seed crops including grass seed. Oregon lawmakers mandated research into the co-existence of canola (Brassica napus) with other Brassica production in the Willamette Valley and House Bill 2427 was signed into law in 2013,...

Exposure and health risk assessment for farmers occupationally exposed to chlorpyrifos in Sri Lanka and drinking water and house dust analysis for chlorpyrifos

Creator:: Aponso, G. Lalith M.
Abstract:: This study was designed to assess chiorpyrifos exposure of a group of farmers by determining internal dose associated with a given application of this insecticide. This involved the monitoring of urinary levels of 3,5,6 trichloro-2-pyridinol (TCP), the major metabolite of chlorpyrifos. Incidental exposure was evaluated by determining the levels of...

Optimizing performance/watt of embedded SIMD multiprocessors through a priori application guided power scheduling

Creator:: Albright, Ryan K.
Abstract:: A method for improving performance/watt of an embedded single-instruction multiple-data (SIMD) architecture using application-guided a priori scheduling of hardware resources is presented. A multi-core architectural simulator is adopted that accurately estimates power, performance, and utilization of various processor components (logic, interconnect and memory). A greedy search is then performed on...

Enhancement of the weed competitive ability of lowland rice (Oryza sativa L.) cultivars

Creator:: Ranasinghe, Lakshman L.
Abstract:: Most of the presently grown cultivars of rice (Oryza sativa L.) have poor competitive ability against weeds if compared with traditional cultivars. Therefore, effective weed control is an important but often costly and difficult management practice in rice crop production. If weed competitive ability of rice cultivars could be improved...
