With recent advancements in material science, industrial operations are being conducted at higher and higher temperatures. This is apparent in the nuclear industry where a division of the field is working to develop the High Temperature Gas Reactor and the Very High Temperature Gas Reactor concurrently. Both of these facilities...
Three studies were conducted to characterize and present early-seral
competition between Douglas-fir seedlings and the surrounding vegetation
communities during Pacific Northwest forest establishment. The first experiment
served as the foundation for this dissertation and was designed to quantify tradeoffs
associated with delaying forest establishment activities by introducing a fallow year...
The objective of this research was to improve our understanding of how
changes in the environment affect ecological processes. Change detection is often
confounded by the large variation found in ecological data due to the difficulty of
finding replicates in nature. Intertidal communities were chosen for studies of biophysical
interactions...
Rapid discoloration and checking of wooden surfaces when exposed outdoors has caused wood to fall out of favor as an outdoor building material, especially in applications where appearance is important. The surface appearance of wood products exposed outdoors can be improved through the application of film forming coatings or by...
In summer 1992, I interned as a Technical Assistant with the Kosrae Bureau of
Planning and Statistics, Kosrae, Federated States of Micronesia (F.S.M). The University
of Oregon Micronesia Program sponsored the internship, which proved to be a unique
professional and cross-cultural experience. The internship, initiated by Mr. Gerson
Jackson, Director...
Four studies were conducted on late-summer diet quality and quantity of cattle (Bos taurus), mule deer (Odocoileus hemionus hemionus), and elk (Cervus elaphus) in response to prior grazing by cattle and elk on mixed-conifer rangelands and on related research techniques. In our first study we assessed a photographic technique to...
The main goal of the study was to investigate high school advanced placement
calculus teachers' subject matter and pedagogical perceptions by examining the following
questions: What are the teachers' perceptions of the concept of limit, the role of limits,
and the teaching of limits in calculus? Additionally, the sampling technique...
