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...
This data set includes the calibrated predictions of Depth, Elevation, Water Surface Elevation, Shear Stress, Vorticity, and Froude Number for three reaches in the Mill Creek watershed, a tributary of the Siletz River, Oregon. The predictions are for bankfull flow before and after the addition of Large Wood using Nays2DH,...
In the Colorado Rocky Mountains, the association of high topography and low seismic
velocity in the underlying mantle suggests that recent changes in lithospheric buoyancy may have
been associated with surface uplift of the range. This paper examines the relationships among
late Cenozoic fluvial incision, channel steepness, and mantle velocity...
Neisseria gonorrhoeae is an exquisitely adapted, strictly human pathogen and the causative agent of the sexually transmitted infection gonorrhea. This ancient human disease remains a serious problem, occurring at high incidence globally and having a major impact on reproductive and neonatal health. N. gonorrhoeae is rapidly evolving into a superbug...
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...
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 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....
This index provides access to infonnation about women in 102 books and journals. The information contained in each entry is only as good as the original and the quality varies considerably. Much of this infonnation has not before been easily accesible in this form. My hope is that this index...
Expanding efforts to develop preventive gonorrhea vaccines is critical because of the dire possibility of untreatable gonococcal infections. Reverse vaccinology, which includes genome and proteome mining, has proven very successful in the discovery of vaccine candidates against many pathogenic bacteria. However, progress with this approach for a gonorrhea vaccine remains...
Low-tech habitat restoration techniques, including Stage 0 treatments, are increasingly applied but often lack robust evaluation of their effects. In 2018, one kilometer of the South Fork McKenzie (SFMK) River, OR was modified to the Stage 0 condition for the benefit of ESA-listed Chinook by raising the incised channel to...
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....
Wet meadow ecosystems are a useful natural laboratory in which to explore feedbacks between biogenic and geologic controls on valley bottom landforms. Characterized by flat valley floors flanked by higher-gradient hillslopes, these meadows are singular both in that they represent depositional features in what is primarily an erosional environment, and...
Oregon Biography Index is intended to serve primarily as a starting point in locating biographies of Oregonians. We have indexed 47 historical volumes which are either entirely devoted to biographies or have large self-contained biographical sections. The profiles in the books vary widely in accuracy and detail. Birth dates of...
Co-teaching and collaboration are an increasingly popular service model for English as a second language (ESL). In this model, the language specialist, sometimes called the ESL teacher, works together with a content teacher, each using their respective expertise to meet the needs of students who are identified as English learners...
Shallow subsurface flow and surface runoff are spatially and temporally variable in forested environments. The location and timing of this runoff depends on both site characteristics (e.g., vegetation, soil texture, geology, and topography) and on time-varying conditions (e.g., soil water content, precipitation type, duration, magnitude, and intensity). Forest management activities...
Neisseria gonorrhoeae is the sexually transmitted pathogen responsible for millions of cases of gonorrhea worldwide each year. Rapidly-spreading antibiotic resistance is diminishing the ability to effectively treat a disease with significant consequences to female and male reproductive health, as well as to neonatal well-being. A protective vaccine has the potential...
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...
M. avium subsp. hominissuis (MAH) and M. abscessus subsp. abscessus (MAB) both belong to the clinically important non-tuberculous mycobacterial (NTM) group that infect immunocompromised patients with AIDS and individuals with underlining lung conditions such as bronchiectasis or cystic fibrosis. The main challenge of treating MAH and MAB patients is an...
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...
Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. For these reasons, the Guin Library...
Most energy policies that are implemented in the United States dictate how energy is produced, distributed, and consumed, but policies generally neglect to fully investigate how these decisions impact population health. Individuals who live near energy sector components are often different to those that reside further away and change over...
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...
The topics in this dissertation center on the snow processes that dominate mountain environments in the Western U.S. and Alaska, particularly in locations lacking long-term observational datasets or locales that are difficult to access in-person. Some are currently glacierized or have been glaciated in the recent past. Each of the...
Radiation exposure to the brain can occur from a variety of events, including space missions, nuclear accidents, and clinical treatments. The effects of high dose radiation are well studied, but those of lower dosage are more elusive. Decline of memory and cognition is observed in patients exposed to low dose...
Families and early care and education (ECE) programs are two important contexts in which young children develop (Bronfenbrenner & Morris, 2006). Nearly half of all preschoolers are cared for in nonrelative care (e.g. child care center, preschool, Head Start, teacher’s home; Laughlin, 2013), and ECE programs have the potential to...
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...
