New detrital mica ages from the Umpqua Group of the Oregon Coast Range provide constraints on models of Eocene sedimentation. Based on sandstone petrography, previous studies assert that the Klamath Mountains to the south are the most likely source region for Umpqua Group sedimentary provenance. However, the presence of Late...
Inner shelf hypoxia has occurred along the Oregon coast between the latitudes 44ºN
and 45ºN since 2002 with increasing duration and intensity, posing a threat to marine
life. The objective of this research was to determine whether variation in respiration
rate explains spatial and temporal variation in hypoxia. Dissolved oxygen...
Ocean acidification (OA) has emerged as an important focus of research and policy in this decade. Ocean acidification specifically refers to changes in the inorganic carbon system in the ocean resulting from its absorption of human-released CO₂ from the atmosphere. Anthropogenic atmospheric CO₂ levels are rapidly increasing; much of this...
The severity of carbonate chemistry changes from ocean acidification is predicted to increase greatly in the coming decades, with serious consequences for marine species- especially those reliant on calcium carbonate for structure and function (Fabry et al. 2008). The Northern California Current Ecosystem off the coast of US West Coast...
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 present research was an exploratory study which investigated the marketing practices of textile-related, home-based business owners. Questionnaires were mailed to 204 textile-related, home-based businesses throughout the continental United States. The final response rate was 42 percent with 86 useable questionnaires. A five-point semantic differential scale was used to measure...
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...
An interior design project was completed by the researcher on the
campus of Oregon State University. The purpose of the project was to
participate in, direct and record the design process of an interior design project
with an emphasis on the use of graphic communication methods.
A chronology detailed the...
The present study examined the influence of country-of- origin on the apparel purchase decision. 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...
A survey of major bean (Phaseolus vulgaris) breeding programs and
seed producing areas in Idaho, Washington, and Oregon was conducted to
determine the occurrence of cucumber mosaic virus (CMV), recently reported
to be seedborne in beans. Some 259 plants, sampled from breeding
lines of diverse germplasm, were found by enzyme-linked...
