Studies on the biosynthesis of the streptolidine moiety of streptothricin F

Creator:: Wityak, John
Abstract:: The loss of all deuterium labels from previous feedings of [2-²H]-, [3,3-²H₂]-, and [2,3,3-²H₃]arginines had indicated the possible intermediacy of β-hydroxy- and β-ketoarginine (30 and 31, respectively) in the biosynthesis of the streptolidine portion of streptothricin F (la). In order to confirm or refute this evidence, D,L-[2,3,3,5,5-²H₅]- arginine (32) was...

Uranium mineralization of the metamorphic aureole of the Spirit pluton, Stevens County, Washington

Creator:: Mitchell, Terry Edward
Abstract:: Several uranium anomalies, with concentrations of U₃0₈ that average below 0.003 percent and reach maximums of 0.069 percent, are associated with black, fossiliferous, pyritic parts of the Ordovician Ledbetter Slate in northern Stevens County, Washington. The most uraniferous parts of the slate occur in small (average of 5 by 30...

Development and broad application of a mass spectrometry based metabolomics platform

Creator:: Kirkwood, Jay Steven
Abstract:: Metabolomics is a comprehensive analysis of small molecules, or metabolites, in a system. Metabolomics is a hypothesis-generating experiment and offers an unbiased analysis of cell metabolism that can aid in the understanding of fundamental biological processes. Metabolomics is widely and broadly applicable in the biological sciences and has been used...

Phyto-edaphic relationships and ecotypic development of Festuca idahoensis in eastern Oregon habitat types of Artemisia tridentata

Creator:: Doescher, Paul Steven
Abstract:: This research assessed certain specific plant-soil and community interrelationships in eastern Oregon habitat types dominated by subspecies of Artemisia tridentata. The first evaluation described plant-induced soil chemical patterns for Artemisia tridentata plant communities of high perennial grass-low shrub and low perennial grass-high shrub composition. Soil concentrations of total nitrogen, organic...

Optimal harvesting of continuous age structured populations

Creator:: Smith, Steven J.
Abstract:: We investigate the optimal harvesting strategies for McKendrick type population models. Models of this type endow the population with a continuous age structure. They consist of a partial differential equation with a boundary condition which involves an integral of the solution. We study two problems, the first concerns the yield...

Effect of defoliation treatments on forage quality, quantity, and species composition of a Lolium perenne (L.) - Trifolium subterraneum (L.) pasture

Creator:: Motazedian, Iraj
Abstract:: As part of investigations to adapt a suitable grazing system in western Oregon, this research was designed to monitor the effects of defoliation treatments on dry matter production, forage quality, regrowth after defoliation, and species composition of a Lolium perenne Trifolium subterraneum pasture for three consecutive growing seasons from 1980...

An observational study of the wind fields associated with GATE cloud clusters

Creator:: Tollerud, Edward I.
Abstract:: The wind and thermodynamic fields associated with eastern Atlantic cloud clusters are studied using radiosonde data from the Global Atmospheric Research Program Atlantic Tropical Experiment (GATE). These data are from the gridded set of winds prepared by Dr. Katsuyuki Ooyama (AOML-NOAA) and Dr. Jan-Hwa Chu (SSEC, University of Wisconsin, Madison)...

Describing the thermal regimes of two northeastern Oregon streams

Creator:: Raven, Sonja E.
Abstract:: Two tributaries of the south fork of the Burnt River, near Unity Oregon were studied during the summers of 2000 and 2001 to determine water heating and cooling patterns. Hourly temperature data were recorded for air, water, and soil parameters at four elevations 150m apart on Barney and Stevens Creeks....

Silvicultural impacts of sheep grazing in Oregon's Coast Range

Creator:: Leininger, Wayne C.
Abstract:: A three-year investigation was conducted during 1980-1982 to evaluate the potential of using herded sheep as a silvicultural tool to suppress brush in Douglas-fir (Pseudotsuga menziesii) plantations of Oregon's Coast Range. Sheep browsing of Douglas-fir was highest in May soon after bud break. Averaged over the 2 years of grazing,...
