WEPP (Water Erosion Prediction Project) is a stand-alone Windows application for predicting water erosion from overland flow on a hillslope. This application was developed by the National Soil Erosion Research Laboratory (NSERL). To make the WEPP application more accessible and easy to use, we created a web version of WEPP,...
Reinhabitation is an approach to building local cultures and economies within industrial society. The food system is a vital starting point. What are the principles of reinhabitory food systems? What are the possibilities for a locally adapted food system in the Marys River region of western Oregon? I describe past...
C. perfringens is a spore-forming, gram-positive, anaerobic pathogenic bacterium capable of causing a wide variety of diseases in both humans and animals. However, the two most common illnesses in humans are C. perfringens type A food poisoning (FP) and non-food-borne (NFB) gastrointestinal (GI) illnesses. Interestingly, these two major diseases are...
This thesis details investigations of marine cyanobacterial secondary metabolism, with emphasis on a strain of Phormidium sp. collected in Indonesia. These studies assessed the effects of nineteen putative elicitor compounds on the growth and metabolite production of five species of marine cyanobacteria, biosynthetic investigation of an intriguing secondary metabolite, phormidolide,...
Copper deficiency and Mo-induced Cu deficiency are nutrition
problems of ruminant livestock in the Burns and Klamath Falls area
of Oregon. Chemical analysis of plant and soil samples was used to
survey Cu and Mo levels in forage in these areas. The objectives
were to assess the possibility of animal...
Azaspiracid-1, a novel marine toxin that contains 9 rings and 20 stereogenic centers, has drawn considerable attention from synthetic groups worldwide due to its structural complexity, which includes a unique trioxabisspiroketal fused to a tetrahydrofuran ring (ABCD rings), a piperidine-tetrahydrofuran spiroaminal system fused to a 2,9-dioxabicyclo[3.3.1]nonane system (FGHI rings), a...

C assimilation, and growth
analysis were done on four cultivars of high yielding soft white
winter wheat (Triticum aestivum L. em Thell), Anza/Sturdy, Hill-

The implementation of advanced hybrid (Monte Carlo/Deterministic) transport methods for realistic test problems has been a challenge due to the overhead efforts associated with interfacing a solution generated by a deterministic solver with a Monte Carlo based radiation transport code. In this work, with the help of Transpire, Inc., a...
