Regular null curves in Regular null curves in L³ always have a time component parametrization. This fact puts the Frenet equations for regular null curves in L³ in a simple form. A fundamental existence and uniqueness theorem for regular null curves in L³ is proved, and applications to geometry are...
The Thomas Kay Woolen Mill operated between 1890 and 1962. The mill produced predominately woolen blankets and woolen fabrics for outerwear garments. Mission Mill Museum Association purchased the woolen mill after its closure in order to develop the property as a museum. The purpose of this study was to provide...

One-hundred and eighty-one adult female sweater purchasers were surveyed directly following the purchase of a sweater for personal use in the Portland, Oregon, metropolitan area. The sample consisted of 138 department store shoppers and 43 discount...
Models of ecosystem carbon (C) balance generally assume a strong relationship between net primary productivity (NPP), litter inputs, and soil C accumulation, but there is little direct evidence for such a coupled relationship. Using a unique 50-year detrital manipulation experiment in a in a mixed deciduous forest and restored prairie...
Four species of the sequestrate fungal genus Elaphomyces are reported from New Zealand: Elaphomyces bollardii sp. nov. associated with Leptospermum spp. and Kunzea ericoides, E. luteicrustus sp. nov. associated with Nothofagus menziesii, E. putridus sp. nov. associated with Nothofagus spp., and an unnamed species associated with Nothofagus spp.
Juvenile Oncorhynchus mykiss migrate extensively in freshwater during fall. We used individual tagging to study the spatial origin, influences, and outcomes of fall migration on fish that emigrated from summer rearing tributaries during fall (early-emigrants) and those that did not (late-emigrants) in the South Fork John Day River, Oregon. Fall...
Desert springs are sensitive aquatic ecosystems that pose unique challenges to natural resource managers and researchers. Among the most important of these is the need to accurately quantify population parameters for resident fish, particularly when the species are of special conservation concern. We evaluated the efficiency of baited minnow traps...
In This Side of Paradise, The Great Gatsby, and several of his short stories, F. Scott Fitzgerald questions the importance of wealth as a factor in supporting happiness and fostering the American Dream on an individual basis. With these texts, Fitzgerald acknowledges that wealth is a factor and, simultaneously, a...
