Characterization of a Sporulation-Specific Kinase in Clostridium perfringens

Creator:: Danielson, Bryan
Abstract:: Clostridium perfringens type A isolates produce the spore-specific enterotoxin, CPE, upon sporulation in the gastrointestinal tract of humans and animals. Spo0A is a response regulator representing the major transcription factor for sporulation initiation in C. perfringens. In Bacillus subtilis, a multicomponent phosphorelay involving five histidine kinases (KinA-KinE), the intermediate response...

Effects of caustic addition on black liquor rheology and thermal characteristics

Creator:: Euhus, Daniel D.
Abstract:: An important by-product of the kraft pulping process, black liquor is currently used in most pulp mills to produce steam in a recovery boiler. Two important black liquor characteristics are viscosity and burning (firing) characteristics, which determine the operating efficiency of the recovery boiler. Kraft black liquor is a complicated...

The Distribution and Abundance of a Non-native Eelgrass, Zostera japonica, in Oregon Estuaries

Creator:: Dudoit, Chana Makale’a
Abstract:: Biological introductions may considerably alter the composition and community dynamics of invaded areas thereby changing many ecosystem processes including productivity, decomposition, nutrient cycling and hydrology. The effects on native species may be obscured by a lack of information on distribution and abundance patterns. The Japanese eelgrass, Zostera japonica, was introduced...

The effect of transverse shifts on the LIGO interferometer (simulation study)

Creator:: Fettig, Doug J.
Abstract:: The LIGO interferometers have reached their designed sensitivity level which is greater than any other interferometer ever built. At this point, it is important to have a proper understanding of small perturbations that might still exist (until now these issues did not come to the forefront because other more critical...

Beyond free will: an empirical case for a capacity model of human agency

Creator:: Helzer, Erik G.
Abstract:: Although the question of free will has persisted throughout the history of philosophy as an important metaphysical consideration, rarely does the inquiry include empirical evidence from other disciplines concerned with human behavior. In this interdisciplinary paper, I combine the wisdom of psychologists, metaphysicians, and philosophers of science to comment on...

Entrapment of Micro-Algae in Modified Alginate Beads for Oxygen and Nutrient Source

Creator:: Hughson, Jason D.
Abstract:: Presented here is an investigation and comparison of two entrapment methods of algae. Conventional calcium alginate bead entrapment is compared to a recently described modified bead entrapment method, utilizing poly(ethylene glycol) and calcium alginate, which results in void or capillary formation within the beads. It is shown that algal growth...

The People's band: U2 and international activism

Creator:: Peterson, Maxie Jean
Abstract:: The end of the Cold War brought about changes within international political relations that resulted in expanded interest in global civil society. Such developments, like globalization and democratization, have encouraged the growth of social and political organizations. Political scientists have found that these inter-governmental and non-governmental organizations have a significant...

The application of geographic information systems for delineation and classification of tidal wetlands for resource management of Oregon’s coastal watersheds

Creator:: Scranton, Russell W.
Abstract:: Resource managers of Oregon’s tidal wetlands require an improved GIS layer for management of existing tidal wetland habitat and areas considered for tidal wetland restoration. A reconnaissance project was initiated, such that interpretations of remote sensing data, the National Wetland Inventory, Oregon Estuary Plan Book and additional management tools were...

Biodiesel in Oregon : an agricultural perspective

Creator:: Lahmann, Emily Loren
Abstract:: Biodiesel is a renewable, non-toxic, and biodegradable diesel fuel made from agricultural feedstocks. With a vibrant agricultural industry, Oregon is positioned to play an important role in the future of this energy source. Limiting factors to widespread biodiesel production include low value of biodiesel feedstock crops, lack of infrastructure, lagging...
