The performance of a combined vapor-compression cycle/ORC is evaluated using waste-heat from a diesel generator. A flat plate microchannel heat exchanger is employed to provide energy exchange between the diesel exhaust stream and an oil loop, which provides energy to a boiler. This study finds an increased diesel duty corresponds...
This study aimed to explore the relationship between grassroots activism, in the form of a plastic bag ban, and social capital. I postulated that grassroots activism would lead to higher levels of social capital. The data was collected through a survey distributed on community bulletin boards, an announcement at a...
The impacts of climate change are being observed worldwide. However, some regions and context specific situations make particular areas more vulnerable to the impacts than others. Alaska’s Kenai River Watershed (KRW) is on the front lines of climate change and may be especially vulnerable to the impacts due to distinct...
Understanding the relationship between motivation, academic achievement, and persistence may help higher education administrators develop plans for increasing student engagement and student success. Prior research on higher education indicated connections between motivation, academic achievement, and persistence, but there has been limited research that relates these concepts to the rural community...
The freshwater trematode Nanophyetus salmincola has been demonstrated to impair salmonid immune function and resistance to the marine pathogen Vibrio anguillarum, potentially resulting in ocean mortality. We examined whether infection by the parasite N. salmincola similarly increases mortality of juvenile Chinook Salmon Oncorhynchus tshawytscha when they are exposed to the...
Online courses and even degree programs are becoming a widespread phenomenon at universities across the United States. Research into the effectiveness of these courses is in the early stages. This qualitative study explored student perceptions of their online class experience using expectancy-value theory as a framework in an attempt to...
In recent years, our ecological knowledge of tropical dry forests has increased dramatically. However, whole components of the ecosystem, like lichenized fungi, remain mostly unknown. Crustose lichens in these forests are so abundant, that they are responsible for the characteristic appearance of a “white bark forest” during the dry season....
A tidally and cross-sectionally averaged model based on the temporal evolution of the quasi-steady Hansen and Rattray equations is applied to simulate the salinity distribution and vertical exchange flow along the Hudson River estuary. The model achieves high skill at hindcasting salinity and residual velocity variation during a 110-day period...
Lichen sensitivity to air quality has been recognized in Europe
for over 125 years: recently Federal agencies in this country have
begun using lichens as air quality bioindicators. This study presents
the results of three different approaches to air quality biomonitoring
using lichens: (1) a lichen community analysis, (2) an...
St. Lawrence Island, Alaska is home to two Formerly Used Defense Sites (FUDS) under remediation by the U.S. Army Corps of Engineers since 1985. After more than two decades the local residents continue to be concerned about inadequate site characterization and cleanup. During the summer of 2005, I collected ethnographic...
The pigeon guillemot (Cepphus columba) population in Prince William Sound has failed to recover from declines that occurred both before and after the Exxon Valdez Oil Spill (EVOS). Post-spill studies of pigeon guillemot breeding biology have identified three potential factors limiting recovery: (1) predation on eggs and nestlings; (2) declines...
Linear M-mode (1D) and later 2-dimensional (2D) measurements of the left atrium (LA) are commonly been used to assess LA size in veterinary studies despite the fact that studies in human subjects have shown that LA volume (LAV) more accurately reflects LA size than linear measurements due to the complex...
A microchannel heat exchanger was designed for diesel waste heat recovery and its performance was evaluated. The 21x15x8 cm unit was constructed from diffusion brazed stainless steel lamina and weighed 11 kg. Operating from a 13.4 kW generator with an exhaust temperature of 500 °C the unit delivered 11.1 kW...
Selenium deficiency in rats results in increased carbon metabolism,
approaching twice the rate of selenium supplemented animals
(normal). This is also reflected in a 50 percent increase in lysosomal
enzyme activity in tissues of selenium deficient animals.
Isolation of rat liver lysosomes shows a 17 percent increase in
membrane thickness...
The purpose of this investigation was to determine whether sex-role
identification differences among college students were related to place
of residence, and if so, whether certain factors affect these
differences. Six hypotheses were developed. The study sought to
ascertain if sex-role identification is related to certain dimensions of
peer association...
Wild fish populations are typically infected with a variety of micro- and macroparasites that may affect fitness and survival, however, there is little published information on parasite distribution in wild juvenile salmonids in three upper tributaries of the Willamette River, OR. The objectives of this survey were to document (1)...
Jalapeño peppers are usually consumed raw and fresh with minimal processing. They
contain antioxidants and bioactive compounds which are of human health benefits.
There have been an increasing number of reports of foodborne outbreaks attributed to
inaccessibility of sanitizers to Salmonella , E.coli and Listeria monocytogenes when
embedded in fruit...
This compilation of theses and dissertations (a part of the OSU Bibliographic Series) for the period 1970-1977 reflects this university's emphasis on research and graduate study. It may be viewed as an indicator of the contributions made to the state of Oregon through graduate study and research at Oregon State...
Oregon’s coast draws millions of visitors every year to witness the natural wonders of one the world’s most vibrant and publicly accessible areas where mountain forests meet sandy beaches and the sea. Communities along the Oregon coast are restricted to narrow stretches of developable land overlying sand deposits between the...
The black grass bug genus Irbisia Reuter was revised. Over 18,000
specimens were examined and information concerning the biology, host
plant and distributional relationships of the species was compiled.
In addition to external characters, the male claspers and vesica, and
the female dorsal libiate plate of the bursa copulatrix and...

The Steller Sea Lion Research Initiative was passed in 2001 to provide funding to help scientists determine causes and solutions for the population crash of Steller sea lions (Eumetopias jubatus). In response to need to understand population dynamics of Steller sea lions, NOAA Fisheries has spearheaded a large-scale, range-wide research...
These studies focused on maximizing the nutrition and safety of raw whole
muscle beef while minimizing quality and shelf-life alteration. The first study used
response surface methodology to predict fluid loss from injected beef strip loins and
steaks as influenced by levels of salt and sodium phosphates (SP) in the...
Rising energy demands and the continual push to find more energy efficient technologies have been the impetus for the investigation of waste heat recovery techniques. Diesel engine exhaust heat utilization has the potential to significantly reduce the consumption of fossil fuels and reduce the release of greenhouse gases, because diesel...
Although fish are a nutritious food source, they also are the main source of methylmercury exposure in U.S. populations. This research examined the risks from methylmercury and benefits from omega-3 fatty acids and selenium from fish consumption. The first study provided the first region-specific quantitative risk/benefit analysis for nine commonly...
Lichens play many important roles in subarctic terrestrial ecosystems by fixing nitrogen, colonizing rock and gravel, stabilizing otherwise bare soil, adding significantly to vegetation biodiversity and serving as the primary food for caribou in the winter. In these chapters, I analyzed lichen community and ecological trait structure along environmental gradients,...
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...
