Remediation of atrazine in irrigation runoff by a constructed wetland

Creator:: Runes, Heather B.
Abstract:: Due to its frequent use in agriculture and its frequent detection in surface water, atrazine was chosen as a model compound to study the treatment capability of a surface flow wetland used to remediate irrigation runoff at a container nursery near Portland, Oregon. Further evaluation of treatment of atrazine was...

Hemoglobin adducts of the organophosphate insecticide azinphos-methyl

Creator:: Bailey, Bonnie J.
Abstract:: Reported here is an investigation to determine if azinphos-methyl (AZM), an organophosphate insecticide, adducts to hemoglobin, and if so, whether the hemoglobin adduct could be used as a quantitative marker of occupational AZM exposure. We hypothesized that AZM, or a metabolite of AZM, binds to hemoglobin in erythrocytes forming an...

The effect of esoterica on institutional goals as measured by the use of cherished terms in the pulpits of the Church of the Nazarene and church growth

Creator:: Parrott, Richard Leslie, 1952-
Abstract:: This is a psycho-socio-linguistic study of language as the primary tool of institutions such as education, government, and religion. These institutions have goals associated with identifying with, communicating with, and influencing individuals in the general public who are not Part of the group. A review of psycho-socio-linguistic theory suggests that...

A study of factors affecting child-centered teaching in elementary grades

Creator:: Hatch, Lynda Sylvia
Abstract:: Some elementary teachers want to be more child-centered in their teaching. They are trying to consider the needs of the students before the coverage of curriculum. Much of the inspiration for this educational approach has come from the British primary schools. The purpose of this study was to see if...

Resilience of large river basins : applying social-ecological systems theory, conflict management, and collaboration on the Mekong and Columbia Basins

Creator:: MacQuarrie, Patrick R.
Abstract:: River basins provide essential services for both humans and ecosystems. Understanding the connections between ecosystems and society and their function has been at the heart of resilience studies and has become an increasing important endeavor in research and practice. In this dissertation, I define basin resilience as a river basin...

A Multi-Tiered Approach Using Daphnia magna to Assess Chlorpyrifos Risk to Aquatic Receptors

Creator:: Maggio, Stephanie A.
Abstract:: Chlorpyrifos (CPF) is a widely used broad-spectrum organophosphate insecticide. Following exposures, CPF and its more toxic oxon metabolite (CPFO) elicit neurotoxic effects by inhibiting the activity of the acetylcholinesterase enzyme (AChE), resulting in altered fitness and death at high doses. Following exposure, organisms bioactivate CPF to CPFO through the Cytochrome...

Biochemical and physiological indicators of behavioral impairment in salmonids exposed to chlorpyrifos and copper

Creator:: Sandahl, Jason
Abstract:: The purpose of this work was to determine if environmentally-relevant concentrations of chlorpyrifos and copper, two commonly detected chemicals in Western surface waters, can negatively impact the biological health of salmonids. Both compounds are highly neurotoxic to fish, but each with distinct biological target sites and mechanisms of action. We...

Continuous monitoring and modeling to assess pesticide exposure in critical habitat for Pacific salmonids

Creator:: Janney, Philip K.
Abstract:: Pacific Northwest and California freshwater resources are key elements in the life history and ecology of Pacific salmon and steelhead listed as threatened or endangered under the Endangered Species Act. Risk to listed Pacific salmonid species can be assessed by evaluating the spatial and temporal co-occurrence of salmonid species at...

Small mammal and bird abundance in relation to post-fire habitat succession in mountain big sagebrush (Artemisia tridentata ssp. vaseyana) communities

Creator:: Holmes, Aaron L.
Abstract:: Fire is an important disturbance mechanism in big sagebrush (Artemisia tridentata) communities, yet little is known about wildlife population dynamics during post-fire habitat succession. I estimated the abundance of small mammals and birds in relation to fire history in mountain big sagebrush (A.t. spp. vaseyana) communities on the Sheldon National...
