Site 35JA42 represents the first protohistoric village
complex excavated in Southwest Oregon. Analyses of animal
bones recovered from the site offer the first significant
insights into human subsistence behaviors in this region.
Although the faunal assemblage is extremely fragmented,
detailed zooarchaeological analysis indicates that deer were
the primary meat resource...
The effects of some soil- and foliar-borne biotic factors on
grain yield and the components of yield were evaluated using five
winter wheat varieties sown at two dates. Within each planting date,
varieties were grown under four different combinations of two soil
treatments (fumigation and nonfumigation) and two foliar treatments...
The two-parameter Weibull function was used to predict forest stand diameter distributions and growth. Diameter distribution models were developed for even-aged Douglas-fir stands, 20 to 40 years old, in Oregon and Washington. In order to test if the two-parameter Weibull function can adequately describe the diameter distributions of such stands,...
Significant post planting mortality of young conifer seedlings often occurs on drought prone sites because seedlings fail to either establish, or maintain favourable water relations. Survival is contingent upon growth which occurs when turgor pressure is above a threshold level. Since growth after planting is influenced by nursery cultural practices,...
An important task of a Variable Speed Generation (VSG)
system is the capability to maintain and control the terminal
voltage at some desired value as determined by the
reactive power dispatch strategy.The main objective is to
design a sub-optimal fixed-parameter controller in the
sense that constraints with respect to practical...
There have been many changes in American society since the 1960's dealing with civil rights and the labor force. These areas, in turn, have influenced and been influenced by changes in education such as Title IX and Title II. The purpose of this study was to investigate the sex-equity characteristics...
In this dissertation we consider the problem of
automating the design of access structures for relational
database systems. The main considerations are effective
and rigorous utilization of the users' usage patterns,
global treatment of the whole design and utilizing most of
the commonly known access structures.
We represent the usage...
Douglas-fir and western hemlock growth and stocking were examined on two neighboring clear-cut watersheds in the Western Cascades of Oregon and related to the intensity of burning and logging disturbance, habitat type, soil type, aspect and the influence of percent cover of both invading Ceanothus species and residual Acer circinatum....
A growing realization that wetlands are potentially
valuable resources has recently stimulated efforts towards
their protection. While a foundation for wetland management
exists, decision makers still lack adequate tools for addressing
issues of wetland preservation vs. development.
Wetland preservation values are often neglected in traditional
market analyses and in the...
