Two objectives of this research were to identify fungi which are
mycorrhizal with western hemlock and to examine the ecology of hemlock
mycorrhizal fungi indigenous to outplanting sites. Another objective
was to evaluate the effectiveness of mycorrhizal inoculation in
improving the performance of outplanted hemlock seedlings.

A self-powered neutron detector (SPND) is a device that, coupled with a current meter, provides a readout proportional to neutron population. This thesis discusses the design parameters of an array of such devices, their characteristics, and the use of these devices as a self-powered neutron spectrometer (SPNS) to provide information...
After traveling to Africa and experiencing the struggles and confusion of interacting with a new culture, I saw the need for some sort of orientation device that would adequately prepare first timers, but also not be too lengthy and daunting for a person that will only be spending a few...
Phylogenetic analyses based on nLSU and ITS sequence data indicate that the sequestrate genus Gigasperma is polyphyletic. Gigasperma cryptica, which is known only from New Zealand, has affinities with the Cortinariaceae whereas G. americanum and two additional undescribed taxa from western North America are derived from Lepiota within the Agaricaceae....
This thesis explores trends and perceptions surrounding nonmedical use of prescription stimulants by university students throughout the United States. Furthermore, this study evaluated how universities in Oregon have responded to increased rates of nonmedical prescription stimulant use on campuses across the country. The following research questions are addressed: 1) What...
Methamphetamine has flooded the media for the past two decades however, this
drug has impacted the nation for many decades prior. Since its synthesis in 1893,
methamphetamine has appealed to various aspects of society including soldiers,
housewives, college students, businessmen, truck drivers, drugged crazed hippies, and
athletes. The extensive effects,...
Supervised exercise interventions can elicit numerous positive health outcomes in
breast cancer survivors. However, to maintain these benefits, exercise needs to
continue long after the supervised program. This may be difficult, as in this
transitional period (i.e., time period immediately following a supervised exercise
program), breast cancer survivors are in...
Design is a process of decision making. Organizations that are dedicated to systematic support of the design process tend to have higher profit margins. Further, studies of system development have shown that early-stage design mistakes have a large impact on incurred costs. Therefore, it is critical to identify methods to...
Two experiments were conducted to study the effects of
melengestrol acetate (MGA) on inhibition of estrus, post-treatment
conception rates in heifers and rats, and MGA given during gestation
on the reproductive performance in rats. MGA was administered
orally to Holstein heifers and by subcutaneous injection to Sprague-
Dawley rats.

Understanding the frequency, magnitude, and nature of explosive volcanic eruptions is essential for hazard planning and risk mitigation. Terrestrial stratigraphic tephra records can be patchy and incomplete due to subsequent erosion and burial processes. In contrast, the marine sedimentary record commonly preserves a more complete historical record of volcanic activity...
