In previous research in Europe, asulam (methyl sulfanilylcarbamate)
was found to be a potentially useful herbicide for controlling
broadleaf dock Rumex obtusifolius L. ) in permanent pastures.
Asulam was also reported to have a low margin of safety when used
on common pasture species. Field studies were conducted in western...
The intention of this undergraduate research project was to design and build a fully functional high-vacuum chamber testing environment for use in the development of ion propulsion engines. This project was conducted in an effort to aid ongoing projects between the Deep Space Propulsion Group (DSPG) at Oregon State University...
Eliminating physical activity disparities among ethnic minorities in the U.S. is important. Cultural differences have been found to be plausible contributing factors associated with such disparities. Therefore it is important to investigate and understand the mechanisms by which diverse aspects of cultural experiences affect physical activity participation among ethnic minorities,...

A life course perspective provide a meta-theoretical framework to understand human development. This perspective is characterized by studying the changing lives within the changing environment (George, 2004). Building upon the literature in the psychosocial paradigm and ecological models, Manuscript 1 discusses the uniqueness and the practical importance of a life...

Through this dissertation, the quality of freely available physical activity promotion web articles that lay adults would likely locate online was critically appraised and theoretically analyzed. Three broad categories were considered. They were 1) message consistency with national health guidelines for physical activity; 2) suitability for health-related communication; and 3)...
A quantal response model, more general than the usual logistic
model, is introduced. This model takes into account sources of
variability, or experimental error, other than that arising from variability
in response between individual organisms (or other objects on
test). It is assumed that this extra source of variation is...
Power planning efforts in Oregon require accurate information
about hydroelectric potential. Potential uses for Geographic Information
Systems (GISs) are being investigated by three Oregon planning agencies.
This paper presents a method in which a 616 is used to help identify and
reduce uncertainty in previous hydroelectric inventories. Uncertainty with
respect...
The grid geometry plays a vital role in the performance of gridded ion thrusters. It can dramatically impact the erosion rate and thrust. Designers push the limits of electric in-space propulsion by optimizing grid parameters through simulation. At the same time, computational models of plasma physics are intensive. A baseline...
An expedient approach to the synthesis of a wide range of highly programmable biaryl templates has been accomplished. Utilizing the Diels-Alder [4+2] cycloaddition, a wide range of tri- and tetra-ortho-substituted biaryls have been synthesized in only three to four steps from commercially available materials. We have successfully synthesized entire classes...
A recipe as a piece of text can tell a variety of stories as well as any other. Using a feminist rhetorical analysis, I read my grandmother’s personal recipe journal to show that her writings contain valuable information about women’s lives in twentieth century Poland. Through the close examination of...
