Development of a colorimetric test kit to determine enzymatically produced pyruvic acid in sweet onions

Creator:: Merrill, Dawn C.
Abstract:: Sweet onions are valued for their unique flavor and praised for their health and dietary character. Onion sweetness is perceived as the degree of pungency decreases. Pungency can be quantitatively determined in onions by measuring enzymatically produced pyruvic acid. The onion industry quantifies a sweet onion as one having a...

The effects of thinning on forest-floor small mammals in the Coast Range of Oregon

Creator:: Larson, David J.
Abstract:: Thinning of young Douglas-fir forests has the potential to enhance structural diversity and improve habitat for wildlife. I examined the effects of thinning and thinning intensity on abundance and demographic characteristics of forest-floor small mammals in the Coast Range of Oregon 5 and 6 years after thinning had occurred. Thinning...

Characterization by optical methods of the heat denaturation of bovine serum albumin (BSA) as affected by protein concentration, pH, ionic strength and sugar concentration

Creator:: Kongraksawech, Teepakorn
Abstract:: The thermal denaturation of proteins has been extensively studied using several methods including differential scanning calorimetry (DSC). A custom-built optical system was used to study thermal effects on protein as an alternative method to DSC measurements. It was used to investigate the thermal stability of bovine serum albumin (BSA) with...

Foam enhancing properties of hop bitter acids and propylene glycol alginate

Creator:: Kunimune, Takeshi
Abstract:: The following two projects have been carried out to clarify the impact of these foam stabilizers, and to compare their foam stabilizing power to one another as well as the cling ability. The first project investigated the impacts of four commercially available hop- derived foam stabilizers; iso-alpha-acid (Iso), rho(dyhydro)-iso-alpha-acid (Rho),...

Essays on conservation policies and agricultural nonpoint source pollution control

Creator:: Tanaka, Katsuya
Abstract:: This dissertation consists of three papers on agricultural nonpoint source pollution and control. The first paper focuses primarily on agricultural land use changes under alternative conservation policies. The second and third papers address environmental implications of these policies and their cost effectiveness. In the first paper, the effect of alternative...

Effects of Medicinal Herbs on Contraction Rate of Cultured Cardiomyocyte. Possible Mechanisms Involved in the Chronotropic Effects of Hawthorn and Berberine in Neonatal Murine Cardiomyocyte

Creator:: Salehi, Satin
Abstract:: Herbs have been used for many centuries in diverse civilizations for the treatment of heart disease. Only a few natural supplements claim to have direct cardiovascular actions including hawthorn (Crataegus spp.) and berberine derived from the Berberidaceae family. Several different studies indicate important cardiovascular effects of hawthorn and berberine. For...

Dietary soy and green tea in the prevention of prostate cancer

Creator:: Hsu, Anna
Abstract:: Prostate cancer risk is significantly lower in Asian countries compared to the US, which has prompted interest in the chemo-preventative action of dietary components such as soy and green tea commonly found in Asian diets, such as soy and green tea. Studies have suggested that soy isoflavones and green tea...

Patterns of natural selection and demography in coastal Oregon coho salmon (Oncorhynchus kisutch) populations : evidence from neutral and olfactory receptor gene-linked markers

Creator:: Johnson, Marc Aaron
Abstract:: For Pacific salmon, the evolution of local adaptations depends upon the species' propensity to return, or "home", to natal streams at time of reproduction. Pacific salmon use olfactory cues to guide homing behavior, yet little is known about the genetics of olfaction in salmon. In this study, I use putatively...

Effects of thinning on forest-floor vertebrates and analysis of habitat associations along ecological gradients in Oregon coastal Douglas-fir forests

Creator:: Suzuki, Nobuya
Abstract:: Thinning has the potential to increase structural diversity of managed forests for wildlife. During 1994-1996, I conducted experimental and observational studies using pitfall trapping to assess short-term and potential long-term effects of thinning on abundance and reproduction of forest-floor vertebrates in Douglas-fir (Pseudotsuga menzeisii) forests of the Oregon Coast Range....

Synthesis of novel ambifunctional atropisomeric 2,2',6,6'-tetrasubstituted biphenyls and investigation of their properties and organocatalytic activity

Creator:: Sephton, Mark Alan
Abstract:: Ambifunctional axially chiral 2,2',6,6'-tetrasubstituted biphenyls containing nucleophilic (or basic) functional groups juxtaposed with hydrogen-bond donors were synthesized and their properties studied. Applications for the prepared biaryls as potential organocatalysts for enantioselective carbon-carbon bond forming reactions were examined. Processes investigated included: aldol, Michael, nitroaldol (Henry), and Baylis-Hillman reactions. The novel amidoamine...
