The effect of wine matrix on the analysis of volatile sulfur compounds by solid-phase microextraction-GC-PFPD

Creator:: Davis, Peter M.
Abstract:: Constituents of the wine matrix, including ethanol, affect adsorption of sulfur volatiles on solid-phase microextraction (SPME) fibers, which can impact sensitivity and accuracy of volatile sulfur analysis in wine. Several common wine sulfur volatiles, including hydrogen sulfide (H2S), methanethiol (MeSH), dimethyl sulfide (DMS), dimethyl disulfide (DMDS), dimethyl trisulfide (DMTS), diethyl...

Estimating the value of irrigation water transferred to instream flow : A case study of Umatilla County, Oregon

Creator:: Ugrinska, Monika P.
Abstract:: Agricultural water supplies are becoming increasingly uncertain in the western United States due to elevated demands from competing water users, environmental restrictions on surface water withdrawals as a result of the establishment of the Endangered Species Act in 1973, and potential climatic changes. Since many rural communities in the West...

Supplemental feeding influences reproductive success of the Hawaiian goose (Branta sandvicensis) at Haleakala National Park, Maui, Hawai'i

Creator:: Tamayose, Joy
Abstract:: Low reproductive success has been typical of high elevation populations of the Hawaiian goose (Branta sandvicensis) or nēnē. Researchers identified predation and inadequate nutrition as limiting factors. Reproductive success remained low in most years despite on-going predator control programs. I used a supplemental feeding program over two breeding seasons in...

Assessing cumulative influences of watershed-scale landuses on reed canarygrass (Phalaris arundinacea L.) abundance

Creator:: Inahara, Satomi
Abstract:: The West Eugene Wetlands, Eugene, Oregon, which provide habitat for number of endemic and endangered plant species, are currently threatened by a Reed canarygrass (Phalaris arundinacea L.) invasion. This study addresses the hypothesis that Phalaris spread can be explained in part by using watershed-scale landuse patterns as surrogates of the...

Introgression between jointed goatgrass (Aegilops cylindrica) and wheat (Triticum aestivum)

Creator:: Snyder, Jeremy R.
Abstract:: Hybrids between wheat and jointed goatgrass have long been presumed to be sterile; however, seed were found on hybrid plants in 1990. Field studies were conducted in 1995 and repeated in 1996. One to ten hybrid plants were planted in variable populations of wheat and jointed goatgrass to determine the...

Development of organocatalyzed, intramolecular heteroatom Michael addition and application towards alkaloid synthesis

Creator:: Carlson, Erik
Abstract:: Effective methods for the enantiopure formation of substituted piperidine rings are significantly important due to their presence in alkaloid products. A valuable method to form these ring systems would be via an intramolecular heteroatom Michael addition from the corresponding enone or enal. Described herein is a methodolgy that has been...

Evaluation of straw wattle placement and surficial slope stability

Creator:: Rikli, Anthony M.
Abstract:: Straw wattles are common erosion control devices used to trap sediment. This thesis studies the relationship of straw wattles on slope stability through a case study demonstrating their use on steep slopes (1.5H:1V) for the US20 highway realignment project. Several surficial slope failures have occurred on these fill slopes, often...

A dataflow mechanism for supporting query optimization

Creator:: Kalvin, Patricia M.
Abstract:: The objective of this thesis is to develop a tool which can be used to implement query processing algorithms produced by a query optimizer. The tool should have the following properties: (1) it should support a description of the query solution in a dataflow-like language, (2) it should support data...

Pollination and pollinators of pumpkin and squash (Cucurbita maxima Duchesne) grown for seed production in the Willamette Valley of western Oregon

Creator:: Gavilánez-Slone, Jenny M.
Abstract:: 'Golden Delicious' winter squash (GDWS), Cucurbita maxima Duchesne, provides significant amounts of pollen (24 mg) and nectar (236 μl), but with a low reward of 14% nectar sugar. The quantity of nectar produced per GDWS flower differed between sites and floral sex. The GDWS male flowers had 25% higher sugar...
