Modeling Large Wood Impacts on Stream Hydrodynamics and Juvenile Salmon Habitat

Creator:: Bair, Russell
Abstract:: Large wood (LW) pieces are recognized as an important habitat component for salmon freshwater habitat. As such, they are often used in stream habitat restoration practices despite a lack of knowledge about their impacts on spatial and temporal hydraulic characteristics relevant to fish habitat. In this thesis we present results...

Influence of certain chemicals on the sensitivity of rat embryos to X-irradiation

Creator:: Loawhakasetr, Pathom
Abstract:: The effect of 2-aminoethyl-2-thiopseudourea[superscript .]Br[superscript .]HBr (AET), 2-mercaptoethylamine[superscript .]HC1 (MEA) and trisodium calcium chelate of diethylenetriaminepentaacetic acid (CaNa₃DTPA) on the radiosensitivity of rat fetus was investigated. A total of 1256 fetuses were critically examined. Exposure of rats to 200 r whole-body X-irradiation at 9.5 days of gestation resulted in a...

Liming requirement of selected Willamette Valley soils

Creator:: Peterson, Paul William
Abstract:: There are two major problems associated with soil acidity and lime response investigations: A. Determining how much lime (100% "available" CaCO₃ equivalent) is required to raise a soil pH (or degree of acidity) from its existing level to a specified level - presumably where need for lime is eliminated. B....

Methane emissions from typical manure management systems

Creator:: Steed, John Arthur
Abstract:: Methane is the most abundant organic chemical in the earth's atmosphere. Its abundance in the atmosphere is increasing with time and has reached levels not seen in recent geological history. The methane is produced both naturally, and anthropogenically. One of the sources of anthropogenic methane is manure from domesticated animals....

Prevalence and association of depressive symptoms with physical disability and long-term care use among older American Indians

Creator:: Schure, Marc B.
Abstract:: Health officials have recently been sounding the alarm that depression will soon surpass many of the major medical conditions in causing disability among adults. Recent demographic and health trends are generating public health concern about depression. First, the prevalence of chronic conditions has dramatically increased over the last several generations....

The Hanford Laboratories and the growth of environmental research in the Pacific Northwest, 1943 to 1965

Creator:: Ellis, D. Erik
Abstract:: The scientific endeavors that took place at Hanford Engineer Works, beginning in World War II and continuing thereafter, are often overlooked in the literature on the Manhattan Project, the Atomic Energy Commission, and in regional histories. To historians of science, Hanford is described as an industrial facility that illustrates the...

Groundwater Flooding and Guerrilla Trenches : a Participatory Approach for Flood Control

Creator:: Kemper, Joseph B.
Abstract:: Residents in South Falls City, a small town in the foothills of Oregon's Coast Range, battle intense flooding during the rainy season. Disagreements about surface water management pit neighbor against neighbor, but preliminary evidence suggests that groundwater flooding is an underlying cause. OSU researchers pair the emerging literature on groundwater...

A novel mechanism of chemoprevention by sulforaphane : inhibition of histone deacetylase

Creator:: Myzak, Melinda C.
Abstract:: Targeting the epigenome, including the use of histone deacetylase (HDAC) inhibitors, is a novel strategy for cancer chemoprevention. Sulforaphane (SFN), a compound found at high levels in broccoli and broccoli sprouts, is a potent inducer of Phase 2 detoxification enzymes and inhibits tumorigenesis in animal models. SFN also has a...

Sediment transport modeling and implications for benthic primary producers in Oak Creek, OR

Creator:: Katz, Scott B.
Abstract:: The spatial and temporal variability of sediment transport processes in Oak Creek, OR was investigated and used to explore two study questions: 1) How do sediment transport processes influence benthic algal communities?, and 2) Can fluvial-hydraulic models make accurate predictions of bed load transport rates? Our study was conducted in...
