GIS technology has reached a point where it can be utilized by nonprofessionals in a desktop environment. This paper reviews the implementation of a pilot project for developing a localized-natural resource GIS. The resulting GIS was custom designed to answer questions posed by fish and wildlife biologists who need to...
Metal oxide nanoparticles (MONPs) are manufactured at the greatest rate of any class of nanomaterial due to their wide variety of industrial, commercial, and environmental applications. The sustainable use of MONPs requires a balance of careful consideration of their potential negative environmental impacts with the effective exploitation of their unique...
Interest by public health organizations in scaling-up efficacious health interventions is increasing as the prevalence of arthritis increases and treatment becomes more costly. Although arthritis evidence-based interventions (EBIs) have been found efficacious in improving healthy behaviors and the ability to self-manage symptoms, little research has examined whether scaled-up delivery of...
The sinuous flight behavior of male Douglas-fir tussock
moths, Orgyia pseudotsugata, (McD.), is characterized by
positive anemotaxis and positive chemoklinotaxis and varies
depending on distance from the pheromone source, population
density, and time of day. Visual cues play a minor role
in close-range orientation to a pheromone source, but
males...
T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...
Major objectives of the study involved development of a laboratory
procedure to obtain mating, determining characteristics of female
sex attraction, and determination of the effects of temperature and
humidity on mating and fecundity. The second of two methods devised
to obtain mating, "the vertical airflow technique," was convenient to
employ...
Until recently, occurrence of milk fever (MF) has been attributed to prepartum calcium intake. However, researchers in Iowa have concluded that high prepartum dietary potassium (K) is the major cause of MF. Potassium concentrations have been increasing on manure fertilized soils over the last 20 years. Grasses grown on these...
Frequent 3D spatial mapping of estuaries is critical to understanding and modeling changes that can impact ecological health (e.g., water quality) and ecosystem services (e.g., aquaculture, nutrient cycling, and shoreline stabilization). However, obtaining accurate, repeat topobathymetric data for estuaries is a major challenge. Because shallow estuaries are typically not used...
Two studies were conducted to determine the in vitro metabolic and hormonal effects on glucose 6-phosphate dehydrogenase activity (G6PD) in bovine mammary explants. Study I was conducted to determine the effects of palmitoyl CoA (5 and 25 uM), acetate (1 and 10 mM), spermidine (0.4 mM) and putrescine (0.4 mM)...
The objectives of this thesis were to evaluate the responses of soil microbial communities to physical and chemical disturbances, and associate these responses with soil functional stability and changes in soil quality. The first study consisted of application of heat shocks (HS) to soils with contrasting land use history to...
The study established how community college leaders establish connections
with other community leaders. Connections that form broad and inclusive networks
can be used to develop positive social capital in communities. Results showed that
new community college leaders follow a pattern of community engagement
including the identification of other leaders, making...
Two concurrent studies were conducted to evaluate the effect
of selenium (Se) supplementation on beef cows. Trial 1 was designed
to evaluate the safety and efficacy of two intrareticular Se supplementation
delivery systems. Trial 2 was designed to evaluate the
transfer of Se across the placenta and through the colostrum...
The purpose of this dissertation was to increase our understanding of novice counselors as they initially treat adult survivors of childhood sexual abuse (ASCSA).
The researcher used the grounded theory approach, a qualitative method, in order to describe richly and sensitively the first interactions between counselors-in-training and ASCSA. Seven novice...
A seasonal hair-loss syndrome of native deer began to occur in the Pacific Northwest United States in the mid-1990s. Clinical manifestations of the disease typically include large numbers of chewing lice on Columbia Black-tailed deer (Odocoileus hemionus columbianus) and Columbia White-tailed deer (Odocoileus virginianus leucurus). Expenditure of energy responding to...
Includes 1922 Summer School Graduates.
In the following pages the information, so far as it has been possible to obtain it, is given in the following order for each alumnus: Name, year in which the degree was conferred, degree, course, present occupation, and present mailing address.
Septoria canker remains the most important disease of poplars in intensively managed forest plantations. Genetic resistance has long been considered the best way to manage for this disease. Transgenic resistance mediated by RNA silencing against pathogens and pests (HIGS: host-induced gene silencing) has shown promise in other pathosystems but has...
Anthropogenic induced climate change is predicted to alter distribution of existing plant populations. As plants migrate over space and time, populations often fragment and contract, affecting basic elements of population dynamics (e.g., population size, gene flow, genetic diversity, etc.). Little is known, however, how these impacts on plant species will...
Metabolic and performance parameters of beef calves were
compared between Se supplemented (Se) and control (C) dam
treatment groups from known Se deficient cattle. Four
trials were conducted at three locations involving 50,
36, 25 and 39 experimental dam/calf pairs. Se
supplementation was either two 30 gram oral boluses (90%...
This thesis is a rhetorical analysis of sexual harassment codes on college and
university campuses. The situational model proposed by Lloyd Bitzer is used to examine
representative artifacts from Rice University in Houston, Texas, and Oregon State
University in Corvallis, Oregon, so as to determine whether they operate as "fitting"...
New analytical methods and instrumentation were developed for the determination of dissolved oxygen (DO) at low concentrations in water. The methods were based on monitoring the absorbance increase due to the oxidation of reduced indigo carmine (IC) by oxygen in the sample in different types of spectrometer cells. Spectrophotometer cells...
Eight species of Lathvrus (Fabaceae, Faboideae) endemic to the
Pacific Coast of North America were the subject of a systematic
investigation. Taxa studied included Lathvrus vestitus, Nutt. ex T.
& G., L. laetif lorus Greene, L.. iepsonii Greene, £,. splendens
Kellogg, L. polvphvllus, Nutt. ex T. & G., L. holochlorus...
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...
Metal-oxo clusters can be described as soluble pieces of metal-oxide frameworks. Metal-oxo clusters are also the building blocks for the Metal-Organic Frameworks (MOFs) and coordination polymers. A better knowledge of metal-oxo clusters helps fundamentally understand geosciences, molecular engineering, catalysis, single-molecule magnetism, and MOFs for synthesis, design, and modification of these...
