The settlement history of a remote area in the Coast Range of Oregon, from the 1870s to the 1930s, is examined through factors that may have influenced the success or failure, and length of residence of the homesteaders and later residents. Despite the rugged and isolated location, a small community...
The settlement history of a remote area in the Coast Range of Oregon, from the 1870s to the 1930s, is examined through factors that may have influenced the success or failure, and length of residence of the homesteaders and later residents. Despite the rugged and isolated location, a small community...
This qualitative thesis explored the experiences of self-identified Master-level graduate students who worked four or more years in higher education before enrolling into a student affairs graduate program. The researcher utilized a sample of six semi-structured student interviews along with a review of relevant literature. The data analysis yielded five...
The effects of natural preconditioning (source wood), wood species, and previous
exposure of wood to two types of fungi on the feeding rates and protozoa survival in the
Pacific dampwood termite Zootermopsis angusticollis (Isoptera: Termospidae) were
examined under laboratory conditions. Termites were exposed to four wood species that
had been...
The release of marine debris into the oceans and seas is a global issue of growing concern. These materials are harmful to marine environments and can also transport non-native species to novel habitats. Non-native species floating on marine litter is one of the lesser known impacts associated with marine debris....
The objective of this study was to evaluate the use of aerial photos as a substitute for multiple-year pre-removal field data to assess the downstream channel changes associated with a small dam removal. The Brownsville Dam, a 2.1 m tall concrete dam on the Calapooia River, Oregon, was removed in...
This thesis presents two related studies on the methodology for creating, and
subsequently analyzing, an inverse food web model of an intertidal seagrass bed. The first study (Chapter 2) describes, for the first time in the literature, a method for incorporating isotopic information gained from Bayesian mixing models into an...
Past research and industrial sources have implied that preheating Douglas-fir Pseudotsuga menziesii (Mirb.) Franco prior to peeling veneer was economically feasible. To test this, the effect of treatment temperature on veneer yield and thickness variation for three diameter classes of low grade Douglas-fir logs was studied and related to the...
Thirty bone-in hams from market weight hogs were used
in this study, three groups of 10 each. One group was
brine-cured, frozen and stored (F/S) at -20°C for 90 days
prior to heat processing and smoking. A second group was
similarly cured and frozen, not stored (F/NS), but thawed
immediately,...
