Phosphorus physiology and environmental forcing of oceanic cyanobacteria, primarily Trichodesmium spp.

Creator:: White, Angelicque E.
Abstract:: The biological transformation of dinitrogen gas (N2) into combined forms(termed N2 fixation) by certain genera of oceanic cyanobacteria represents the largest incoming flux of nitrogen to the global ocean. As such, biological nitrogen fixation plays a significant role in the regulation of oceanic productivity and the export of carbon and...

Adapting computer science technologies to bridge critical gaps in proposed Tox21 risk assessment programs

Creator:: Larkin, Andrew
Abstract:: In 2004 the National Toxicology Program published an article describing their intent to pursue toxicology testing and risk assessment practices solely reliant on high throughput in vitro datasets and in silico modeling for dose-response assessments. Support and contributions form regulatory agencies and a significant portion of the life sciences community...

A conceptual model of women entrepreneurs in small businesses

Creator:: Putnam, Carol A.
Abstract:: Women entrepreneurs are an economic force within the American and Oregon economy. Women are starting businesses at two to five times the rate of men. There has been significant research detailing the demographics, barriers, and business management skills of women business owners. Yet, the research to date has been limited...

Spatial and temporal effects of atmospheric deposition, climate, and land management on forest nutrient cycling and biodiversity

Creator:: McDonnell, Todd C.
Abstract:: Emissions largely associated with the combustion of fossil fuels and agriculture has caused elevated atmospheric deposition of nitrogen (N) and sulfur (S) throughout much of the developed world. Increased atmospheric deposition of N and S can lead to soil and surface water acidification and affect forest soil nutrient supply. The...

Harlequin duck demography during winter in Prince William Sound, Alaska : effects of the Exxon Valdez oil spill

Creator:: Esler, Daniel
Abstract:: The 1989 Exxon Valdez oil spill was a major perturbation of nearshore habitats of Prince William Sound, a wintering area for harlequin ducks (Histrionicus histrionicus). This research was designed to evaluate harlequin duck population recovery from the oil spill from 1995 to 1998, using a demographic approach to assess both...

Studies on 1-deoxy-D-xylulose 5-phosphate reductoisomerase from Synechocystis sp. PCC6803 : characterization of mutants and inhibitors

Creator:: Fernandes, Roberta P. M.
Abstract:: In recent years, the methyl erythritol phosphate (MEP) pathway to isoprenoids has been the subject of intensive research. The interest is because isoprenoids have important roles in many cellular processes essential for the survival of several pathogenic organisms, making the inhibition of this pathway an attractive target for the drug...

Biochemical, molecular and physiological characterization of 1-butanol dehydrogenases of Pseudomonas butanovora in butane and 1-butanol metabolism

Creator:: Vangnai, Alisa S.
Abstract:: Butane-grown Pseudomonas butanovora oxidized butane by a soluble butane monooxygenase through the terminal pathway yielding 1 -butanol as the predominant product. Alcohol dehydrogenases (ADHs) involved in butane oxidation in P. butanovora were purified and characterized at the biochemical, genetic and physiological levels. Butane-grown P. butanovora expressed a type I soluble...

Culturing uncultured environmental microorganisms

Creator:: Connon, Stephanie A.
Abstract:: Research on natural environments, over the last decade, is replete with microbial diversity studies that used culture-independent approaches. The cloning and sequencing of the 16S rRNA genes has been the driving force in the expansion of awareness about the great diversity of previously undiscovered microorganisms. Well-known uncultured groups of microorganisms...
