The basic objective of this thesis was to estimate the
economic effects of yield grade standards for carcass beef
on the various market sectors of the Canadian beef industry.
The adoption of the standards was expected to enhance
consumer demand, improve efficiency within the processing
and marketing services sectors, and...
By examining the combined written, ethnographic and physical evidence of a surviving
steam-powered sawmill in the Douglas-fir region of the Pacific Northwest, this thesis
seeks to supply new insights into the operation and adaptability of antiquated machinery
during a period of rapid social and technological change and to develop a...
The term "cowboy" was closely bound to American image long before the
1990s. Rodeo claimed the image of the cowboy from the earliest contests to the
latest and pledged itself to patriotism almost as early. This historical study was
conducted viewing rodeo as a subculture and relating women's role in...
Diclofop (2- [4 -(2, 4-dichlorophenoxy)phenoxy] propanoic
acid), formulated as the methyl ester, selectively kills
barnyardgrass [Echinochloa crus -galli (L.) Beauv.] in several
crops when applied postemergence. Studies were conducted
to determine the effect of soil moisture, barnyardgrass age, and site of exposure on control of barnyardgrass with diclofop. Soil moisture...
The purpose of this annotated bibliography is to guide middle school and high school students into critical thinking about environmental issues. Through keen observation of their bioregion and through an integration of interdisciplinary literature which focuses on Oregon writers, students will be challenged to think, write, and discuss current issues...
The increased use of outdoor recreation as a part of the
American way of life has focused attention on the diminishing ratio

Oregon, where the demand is greatest, there is still ample undeveloped
land for recreation use. There exists, therefore...
Approximately 200 raw prunes were harvested from each of five Italian prune trees near Corvallis every three days for nine consecutive harvest dates. Forty individual fruit from each tree were drawn at random and subjected to a series of fresh fruit quality tests.

In recent years, studies dealing with temperature regulation,
temperature sensitivity, and physiological responses to temperature
in lizards and other reptiles have increased tremendously. It is
notable that snakes have been largely ignored in such studies. This
no doubt is due to their less direct relationship to ancestral endotherms.
However, problems...
Biology of Scaptomyza apicalis Hardy (Diptera: Drosophilidae) was studied in
relation to its host, meadowfoam, Limnanthes alba, a recent oil seed crop grown in the
Willamette Valley, Oregon. Populations of flies and larvae were monitored weekly over
three consecutive crop-years beginning in 1996. Yellow sticky traps gave relative
population estimates...
