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...

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 possibility of international agreements concerning genetically modified organisms in the European Union

Creator:: Fairbrother, Jennifer R.
Abstract:: As genetically modified products come under greater production, tensions surrounding the potential benefits and harms of the technology have appeared in divergent policy between the European Union (EU) and certain member states. The purpose of this thesis is to consider whether some type of international law, also called an environmental...

Effects of phenytoin and carbamazepine on calcium transport in Caco-2 cells and pilot study to compare the role of the Chilean and United States pharmacist from the patient perspective

Creator:: von Borstel, Melinda
Abstract:: Adverse effects of anti-epileptic (AED) medications on bone density have been reported since the 1960s. Phenytoin and carbamazepine, two commonly prescribed AED, are frequently associated with osteomalacia including fractures and reduced bone formation. The mechanism by which AED induces bone loss is not fully explained. We sought to determine the...

Exploring phylogeny of Rhodococcus fascians isolates using 16S ribosomal DNA sequence analysis

Creator:: Sandberg, Eva Song
Abstract:: Rhodococcus fascians is a Gram-positive, pleiomorphic actinomycete that causes leafy gall formation in a wide range of plant hosts. This particular phytopathogen has been a focus of research at the Oregon State University Plant Clinic, a diagnostic laboratory. Phylogeny of R. fascians isolates obtained from Plant Clinic submissions was determined...

A genomic and proteomic characterization of the first cultured oligotrophic marine Gammaproteobacterium from the SAR92 clade

Creator:: Mellbye, Brett L.
Abstract:: High-throughput culturing (HTC) consisting of extinction culturing in autoclaved seawater has led to the isolation and characterization of many novel strains of oligotrophic marine bacteria. Strain HTCC 2207 was isolated from the Oregon coast by the HTC method. Phylogenetic analysis based on 16S rRNA gene sequence showed that this strain...

Location of the neutral axis in wood beams

Creator:: Holm, Sarah C.
Abstract:: It is commonly accepted that for the analysis of wood beams, the neutral axis coincides with the centroid of the beam. Although this assumption is used in analysis, wood is not an isotropic material, as it has different elastic properties in the tangential, radial and longitudinal directions, nor is it...

Discovery and identification of antibacterial agents for dental use

Creator:: Kirkpatrick, Adam G.
Abstract:: Dental disease is a very prevalent and costly disease in which the symptoms, not the disease, are currently being treated. The disease is caused by pathogenic oral bacteria, many of which are a part of the Mutans Streptococci. The objective of this thesis was to find a natural substance that...

Studying abroad and vocabulary use in impromptu essays

Creator:: Mitchell, Kathleen
Abstract:: Spending time in a German speaking country may aid in vocabulary acquisition and production. This study hypothesized a concrete link between written language use and experiences abroad. Intermediate German students’ vocabulary uses in impromptu essays were evaluated by counting the number of total word, unique words, and content words. This...

DNA UV damage-related control of ribonucleotide reductase : possible relationship to mutagenesis and the incidence of and attitudes toward skin cancer in several western nations

Creator:: Stenberg, John C.
Abstract:: Two strains of Escherichia coli were studied to determine the effect of constitutive expression of the SOS DNA damage repair response on the activity of ribonucleotide reductase. Activity of the reductase and cellular deoxynucleoside triphosphate (dNTP) pools were both determined before and after exposure of the cells to ultraviolet radiation....
