The Role of Ascorbic Acid, β-Cyclodextrins, and Alternative Substrates in Dictating Rates of Polyphenol Oxidase-Catalyzed Browning in Potato-Based Reaction Mixtures

Creator:: Jiang, Shu
Abstract:: Enzymatic browning is a consequence of a series of reactions initiated by polyphenol oxidase (PPO)-catalyzed quinone formation. Unwanted browning negatively affects food quality and lowers consumer acceptability. Thus, there is general interest in strategies to control enzymatic browning. Cyclodextrins are cyclic glucan oligosaccharides that form inclusion complexes with a number...

Genetic and phenotypic variation associated with the resistance gene SOD1 in Biomphalaria glabrata, an important intermediate host of Schistosomiasis

Creator:: Bonner, Kaitlin M.
Abstract:: Schistosomiasis afflicts 200 million people and is responsible for 200,000 deaths per year. The infection is caused by a digenean trematode in the genus Schistosoma. The parasite must cycle through both a vertebrate (human) and invertebrate (snail) host to complete the life cycle. My dissertation focuses on the genetic mechanisms...

Investigating Demographic and Evolutionary Factors Important for Fish Reintroduction

Creator:: Sard, Nicholas M.
Abstract:: Reintroduction programs are used to re-establish species back into their historical habitat. Most reintroduction programs have failed and few papers have evaluated factors that may be important to Pacific salmon. The 158 meter tall Cougar Dam has blocked Chinook salmon (Oncorhynchus tshawytscha) from accessing 40 kilometers of historical spawning and...

Foraging ecology of pollinators in the early stages of secondary succession in the western hemlock (Tsuga heteropohylla (Raf.) Sarg.) zone of the Oregon Coast Range

Creator:: Burikam, Intawat
Abstract:: The early stages of secondary succession of the McDonald and Paul Dunn State Forests, Corvallis, Oregon, were grouped into three stages; herb, herb-shrub, and shrub, based on vegetation types. Flowers of herbaceous species and residual shrubs dominated in the early years after clear-cutting. Woody plants became increasing abundant in the...

Riverscape genetics of Oncorhynchus tshawytscha (Chinook salmon) in Siletz River, OR

Creator:: Davis, Chanté D.
Abstract:: Traditional analysis in population genetics evaluates differences among groups of individuals and, in some cases, considers the effects of distance or potential barriers to gene flow. However, many forces may shape genetic variation of organisms in riverine systems. Similarly complex research linking habitat heterogeneity and configuration to genetic structure has...

Development and experimental evaluation of branch-and-bound algorithms for determining optimum static job-shop production schedules

Creator:: Ramalingam, P. Rama, 1941-
Abstract:: Branch-and-Bound algorithms are developed to optimally schedule static single- and multi-stage job-shop productions. The 'corollary' of the study is to experimentally verify the effectiveness of branch-and-bound algorithms to overcome the "curse of dimensionality" due to the combinatorial nature of job-shop scheduling problems. The static scheduling problem contemplated in this dissertation...
