An overall systems design code was developed to model
an advanced in-core thermionic energy conversion based
nuclear reactor system for space applications at power
levels of 10 to 50 kWe. The purpose of this work was to
provide the overall shell for the systems code and to also
provide the...
The alien abduction phenomenon has garnered considerable media attention in the last fifteen years, including many representations in books, film, and television. An overview of significant abduction literature is presented. Contrasts and comparisons are noted between popular written accounts and both the visual representations they engender and reports outside the...
In recent years, several interrelated forces—prolonged drought, growing populations, height-ened environmental protections, sustained agricultural use, and hydrologic alterations due to climate change—have increased pressure on water users in the Western United States, where the agricultural sector accounts for up to 90% of total water withdrawals. Technology im-provements developed since the...
This thesis merges the fields of Ecology and Anthropology by applying Habitat Suitability Modeling to the relationship between people and plants in the Pacific Northwest. In it, I create and optimize two Maxent habitat suitability models for camas (Camassia spp.) in Oregon. The first model describes the physical environment of...
Energy issues are becoming one of the most pressing topics in today's political and cultural landscape, particularly in the midst of the climate crisis. Globally, a variety of renewable energy projects are under development to meet energy demand without continuing to overburden the natural environment of our planet, with profound...
Certain species of the orders Myxobacterales and Pseudo-monadales are well-known antagonists. Pseudomonas fluorescens
and Pseudomonas putida have been reported to produce bacteriostatic
and bactericidal substances. Among the myxobacteria there
are various species which are known for their ability to produce
lytic enzymes and antibiotics. Organisms from both of these groups...
Phaeocryptopus gaeumannii is a pathogenic fungus on Douglas-fir needles which has become a serious threat to timber production in the last decade along the Oregon coast This research was undertaken to describe the general biology and pathology of F. gaeumannii on Douglas-fir needles and how environmental variables affect fungal development....
The invasive annual grass ventenata (Ventenata dubia) has become an increasing problem within western rangelands. Forage quality of areas infested with ventenata is reduced as its high silica content makes it unpalatable to livestock and wildlife. In the following study, I examined whether significant presence of ventenata affects habitat use...
