Establishment of an in vitro model to study persistence in Mycobacterium avium subspecies hominissuis

Creator:: Armstrong, Elyssa L.
Abstract:: Mycobacterium avium subspecies hominissuis (MAH) is the most common pathogen among non-tuberculous mycobacteria, causing disease in immunocompromised individuals. An intracellular bacterium, MAH resides within the phagosome, a vesicle formed by macrophages as they engulf invading pathogens. Here, a subpopulation of MAH regresses into a nonreplicative state called persistence, allowing them...

Forms of Life: Goethe’s Impact on Twentieth-Century Anglophone Botany and Morphology

Creator:: Hahn, Andre M.
Abstract:: This dissertation examines the impact of the German naturalist and literary figure Johann Wolfgang von Goethe’s ideas on twentieth century Anglophone plant morphology and biology. Goethe interpreted the organ forms of flowering plants as metamorphoses of each other. His literary, historical, and philosophical writings suggest themes of alienation from and...

Glyphosate-resistance in Italian ryegrass (Lolium multiflorum): evaluation and investigation of the mechanisms of resistance

Creator:: Perez-Jones, Alejandro
Abstract:: A suspected glyphosate-resistant Italian ryegrass (Lolium multiflorum) (OR) population was collected from a filbert (Corylus avellana L.) orchard near Portland, OR. Based on the dose-response experiments conducted in the greenhouse, it was found that the suspected glyphosate-resistant population was approximately fivefold more resistant to glyphosate than the susceptible (S) population....

Graphical models for multivariate spatial data

Creator:: Irvine, Kathryn M.
Abstract:: In this thesis we focus on a graphical model for multivariate spatially correlated data--isomorphic chain graphs (ICG; Gitelman and Herlihy, 2007). We feel ICG allow flexibility for modeling spatial correlation and are intuitively appealing because each model has an associated graph that visually represents a complex multivariate system. We examine...

Forest restoration and fuels reduction on non-industrial private land in northwestern California

Creator:: Latimer, Lisa Marie
Abstract:: This thesis explores the complexity of relationships between communities and the ecosystems in which they live through a focus on forest restoration and fuels reduction on private land. As a case study, research took place in the Klamath-Siskiyou region of rural Northern California, in Humboldt and Siskiyou counties. The research...

Beckett, Barthelme, and Vonnegut : finding hope in meaninglessness

Creator:: Britten, Alex M.
Abstract:: This thesis is a study of the shifting philosophical trends in the works of Samuel Beckett, Donald Barthelme, and Kurt Vonnegut as representations of a greater shift from modernism to postmodernism. I have chosen to explore Beckett's plays Waiting for Godot and Krapp's Last Tape, Barthelme's short stories "Nothing: A...

Evaluating microbial indicators of environmental condition in Oregon rivers

Creator:: Pennington, Alan Travis
Abstract:: Traditional public health bacterial indicators of water quality and the Biolog® system were evaluated to compare their response to other indicators of stream condition with the state of Oregon and between ecoregions (Coast Range, Willamette Valley, Cascades, and Eastern Oregon). Forty-three randomly selected Oregon rivers were sampled during the summer...

A computer-assisted qualitative data analysis framework for the engineering management domain

Creator:: Saeedi, Amirali
Abstract:: Qualitative data analysis (QDA) is a time consuming and, potentially unreliable research activity. In qualitative research, a number of tasks must be repeated for every new research case, even if each case is closely related or is in the same area of study. Existing QDA applications provide users with a...

An Integrated Approach to Gauge the Effects of Global Climate Change on Headwater Stream Ecosystems

Creator:: Bury, Gwendolynn W.
Abstract:: Climate change is predicted to affect ecosystems, including systems already stressed by human impacts. One ecosystem that is already highly impacted by human land use is the cold headwater stream system of the Pacific Northwest. One method of assessing the function of an ecosystem is by using an indicator species....

Tolerating processor-memory performance gap

Creator:: Lai, Shih-Chang
Abstract:: While the performance gap between microprocessors and main memory is ever increasing each year, cache memory has been a bridge to alleviate this discrepancy. In this thesis proposal, we introduce three techniques to tolerate this processor and memory speed imbalance. First, we propose the bloom filter scheme to identify which...
