Scale Up & Optimization of the Liquid Carbon Dioxide Extraction of Orange Oil with Dry Ice

Creator:: Fraser-Hevlin, Brenden C. S.
Abstract:: Essential oils have numerous chemical and therapeutic applications. Some oil extraction methods, including steam distillation, require a large energy input. An alternative technique with a lower energy demand is the extraction of oils using supercritical liquid carbon dioxide (CO2), which extracts essential oils with minimal environmental impact. While this often...

Restoration of Tillamook Bay : Project Planning

Creator:: Hevlin, William A.
Abstract:: The objective of this project is the production of a Tillamook Bay restoration plan which is designed to revitalize the bay's biological productivity and thereby stimulate economic opportunity in the region. A selected planning team will assess the cumulative impacts on the bay from accelerated sedimentation. The team will develop...

Investigating Transcriptional Control of Specialized Gene Expression in Plants

Creator:: Fraser, Valerie N.
Abstract:: Specialized or secondary metabolism is a collection of pathways and small molecules that, while beneficial to an organism, are not strictly necessary for survival. Plants use secondary metabolites to, among other things, attract pollinators, defend against biotic and abiotic stressors, and form symbioses. Natural products from plants have seen an...

A novel framework for uncertainty propagation in river systems based on performance graphs using two-dimensional hydrodynamic modeling

Creator:: Gifford-Miears, Christopher H.
Abstract:: This thesis presents a novel approach for propagation of uncertainty in river systems. Errors in data observations and predictions (e.g., stream inflows), in model parameters, and resulting from the discretization of continuous systems, all point to the need to accurately quantify the amount of uncertainty carried through the modeling process....

Foraging Niche Separation of Adélie (Pygoscelis adeliae) and Gentoo (P. papua) Penguins During the Breeding Season at Palmer Station, Antarctica

Creator:: Pickett, Erin
Abstract:: Climate-induced range overlap can result in novel interactions between similar species and potentially lead to competitive exclusion. The Western Antarctic Peninsula is one of the most rapidly warming regions on Earth and is experiencing a poleward climate migration. This transition from a polar to sub-polar environment has resulted in a...

Biosynthesis of blasticidin S : mechanistic and stereochemical investigations

Creator:: Prabhakaran, P. C.
Abstract:: Feeding of [3-¹³C, 2-¹⁵N]arginine, 38a, unequivocally established that the β- arginine moiety of blasticidin S, 1, was formed from α-arginine by an intramolecular migration of the α-amino group to the β- position. Further feedings using chirally deuteriated arginines 38e and 38f revealed that the aminomutase process occurred with inversion of...

Columbia River Estuary Marina Study

Creator:: Fraser, Michael B.
Abstract:: The goal of this report is to develop information to benefit the planning and operation of marinas within the CREST area, as well as to generate data for use by local Chambers of Commerce, planners, regulatory agencies, Port Authorities and private developers. It is, however, the commercial, charter and recreational...

A study of off-farm agricultural work experience programs in Oregon high schools

Creator:: Fraser, William Stewart
Abstract:: Funds alloted from the Vocational Education Act of 1963, Public Law 88-210, opened up an entirely new dimension in vocational agriculture programs throughout the nation. The new dimension is an amendment to the period beginning with the Smith-Hughes Act in 1917. Up to the time of the Vocational Education Act...

Studies on purification and characterization of an autolytic enzyme from cell walls of Bacillus subtilis

Creator:: Brown, Willie Claiborne
Abstract:: The purpose of this investigation was to purify and characterize the autolytic enzyme from cell walls of Bacillus subtilis 168. The crude enzyme was obtained by autolysis of purified cell walls in buffer at 37° C. Two purification methods were developed. The first involved fractional precipitation with ammonium sulfate. The...
