Himeradine A : synthetic efforts towards himeradine A and related natural products, a Michael reaction focused approach

Creator:: Collett, Nathan D.
Abstract:: Lycopodium alkaloids have generated enormous amounts of interest from the scientific community, both as synthetic targets and for their medicinal properties. Herein is described work towards a unifying approach to large segments of the Lycopodium family. An organocatalyzed intramolecular heteroatom Michael reaction method, for the construction of piperidine and piperizine...

Rearing density as a driver of adaptation to captivity and traits under selection by domestication in hatchery reared steelhead (Oncorhynchus mykiss)

Creator:: Thompson, Neil F.
Abstract:: Releasing hatchery reared salmon and steelhead to supplement threatened and endangered populations is a widely used conservation tool. One issue with this strategy is hatchery fish have lower reproductive fitness than wild fish when spawning in the wild. One of the drivers of fitness loss in steelhead is adaptation to...

Aqueous complexation of citric acid and DTPA with selected trivalent and tetravalent f-elements

Creator:: Brown, M. Alex
Abstract:: Carboxylic acids have played an important role in the field of actinide (An) and lanthanide (Ln) separations and the reprocessing of irradiated nuclear fuel. Recent bench-scale experiments have demonstrated that 3-carboxy-3-hydroxypentanedioic acid (citric acid) is a promising aqueous complexant that can effectively aid in the separation of transition metals from...

The GEK signatures of lowest mode internal waves

Creator:: Lipparelli, Michael Arthur
Abstract:: Present GEK (Geomagnetic Electrokinetograph) theory is extended to include internal waves of the lowest mode. The predicted towed electrode GEK signal is determined to second-order for long-crested internal waves in a finite but deep ocean. The analysis includes the determination of GEK signatures for small amplitude and finite amplitude interfacial...

Effects of ultraviolet-B radiation on marine phytoplankton

Creator:: Behrenfeld, Michael Joseph
Abstract:: Global increases in ultraviolet-B radiation (UVBR:290- 320 nm) resulting from decreases in stratospheric ozone concentration have the potential to alter marine primary production and affect global climate and marine trophic dynamics. Effects of UVBR on phytoplankton carbon fixation were determined from open ocean exposure studies conducted off the coast of...

Effect of iron redistribution in soils on cesium magnetometer surveys at the Oregon State University research dairy

Creator:: Rogers, Michael
Abstract:: Contamination events at Oak Creek, which runs through Oregon State University Research lands, prompted investigations into alternate transport mechanisms for moving liquid effluent from OSU Diary lands to Oak Creek. Magnetometer surveys conducted at the Diary identified magnetic signatures spatially associated with sub-surface locations of drain tiles, a 12-inch pipe,...

Computer simulation of phase transitions in zirconia

Creator:: Love, Michael J.
Abstract:: Experimental data on the structural phase changes in zirconia are summarized. The computational techniques of molecular dynamics are reviewed and equations of motion are formulated which allow the study of phase changes as a function of temperature and pressure. The molecular dynamics program NPT which was written for this purpose...

Conformation and reactivity studies of some bicyclo(3.3.1) nonane derivatives

Creator:: Sturmer, David Michael
Abstract:: New syntheses for 2-bicyclo(3.3.1)nonanone and 7-bicyclo-(3.3.1)nonen-2-one were developed. The saturated ketone was prepared from phenol and acrylonitrile via a novel intramolecular S[subscript N]2 cyclization process. A Friedel-Crafts cyclization of 3-(3-cyclohexenyl)propanoyl chloride permitted synthesis of the unsaturated ketone from 4-cyclohexene carboxaldehyde. The formation of the bicyclo(3.3.1)nonane rather than a bicyclo(3.2.2)nonane skeleton...

Thymidine kinase mRNA and protein levels during myogenic with drawal from the cell cycle : identification of an mRNA-independent regulatory mechanism

Creator:: Gross, Michael Karl
Abstract:: Replication associated protein and enzyme activity levels increase as cells enter S-phase of the cell cycle and diminish as cells leave S-phase. Accordingly, replication associated functions decrease as myoblasts withdraw from the cell cycle to terminally differentiate. In an effort to understand signals effecting growth associated expression of genes, the...

Natural history and ecology of larval Lost River suckers and larval shortnose suckers in the Williamson River-Upper Klamath Lake System

Creator:: Cooperman, Michael S.
Abstract:: We monitored larval Lost River and shortnose suckers from natal beds in the Williamson and Sprague rivers to nursery grounds in Upper Klamath Lake. Downstream movements occurred at night, in the middle of the channel, and on the falling limb of the hydrograph. Ages, sizes, and developmental stages of larvae...

On the evolution of correlated color traits in garter snakes

Creator:: Westphal, Michael F.
Abstract:: How complex traits evolve continues to be a major focus of evolutionary investigation. A current topic of debate is the hypothesis that the phenotypic integration of complex traits gives rise to evolutionary constraints. I studied two color traits in the common garter snake, Thamnophis sirtalis, that show a high level...

Characterizing drivers of microbial community structure and function in diverse marine sediments

Creator:: Graw, Michael F.
Abstract:: Marine sediments are one of the largest habitats for microbial life on earth. These microorganisms play critical roles in biogeochemical cycling both within the subsurface and between the sediment and water columns. However, microbial communities in sediments are highly heterogeneous and the factors defining microbial community structure and metabolic function...
