Photobiological hydrogen production from the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in sol-gel processed silica

Creator:: Dickson, David J.
Abstract:: Photobiological hydrogen production from live cells of the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in silica gel was investigated. Hydrogen is a dense energy carrier with potential to reduce dependence on fossil fuels, provided a renewable and sustainable means of production can be achieved. Under certain conditions, Synechocystis sp. PCC...

Metabolic engineering of cyanobacteria to optimize photobiological hydrogen production

Creator:: Luterra, Markael
Abstract:: Photobiological hydrogen production -- the use of photosynthesis to split water into hydrogen and oxygen -- presents an opportunity for efficient and large-scale solar biofuel development. One of the major challenges in this area is competition for reductant between the hydrogen-evolving hydrogenase enzyme and other metabolic pathways. In this work...

Optimization of environmental conditions and electron flow for enhanced hydrogen production by cyanobacterial species Synechocystis sp. PCC 6803

Creator:: Burrows, Elizabeth H.
Abstract:: Many conditions affecting hydrogen (H₂) production by the cyanobacterium, Synechocystis sp. PCC 6803, were optimized to yield maximum H₂ accumulation. Biological H₂ production from photosynthetic species is a promising form of renewable energy since an abundant supply of sunlight hits the Earth every day, and photosynthetic bacteria can harness this...

A comparison of the relative effectiveness of teaching composition by closed-circuit television and by conventional classroom procedures

Creator:: Patty, Austin Horace
Abstract:: This study was designed to test the relative effectiveness of teaching Writing 111 at Oregon State University by closed-circuit television as compared with conventional classroom procedures; the hypothesis was that the students taught by television (the experimental group) would achieve as well as the students taught in conventional classrooms (the...

Biologically active cyclic depsipeptides from marine cyanobacteria

Creator:: Medina, Rebecca A.
Abstract:: This thesis describes the chemical investigation of marine cyanobacteria collected in Madagascar and Panama with an emphasis on the isolation and structure elucidation of medicinally relevant secondary metabolites. A collection of the marine cyanobacterium Lyngbya majuscula from the Radames Islands, Madagascar yielded two new cyclic depsipeptides, radamamides A and B,...

Climate Change Impacts to Estuarine Hydrodynamics: Tools, Methodologies, and Predictions

Creator:: Parker, Kai A.
Abstract:: Coastal communities in the U.S. Pacific Northwest (PNW) are rapidly engaging with the idea that hazards and environmental pressures are changing and may be characteristically different in the near future. This has led to a need for scientific knowledge and tools that can help coastal communities prepare and build resilience...

A causal study of attitudes toward intercollegiate athletics of Oregon State University undergraduate students in three academic majors

Creator:: Ruhl, Glenn David
Abstract:: The purpose of this study was to determine and explain attitudes toward intercollegiate athletics of undergraduate students in three academic majors attending Oregon State University. The attitudes of a proportionate random sample consisting of 215 students were measured according to their responses to thirty-two Likert scale items containing six sub-scale...

An assessment of needs and interests for multicredentialed allied health workers in rural Wisconsin hospitals

Creator:: Bauer, Annabel Bernice
Abstract:: The study examined multicredentialed allied health workers in rural Wisconsin hospitals. The objectives identified differences in perceptions between rural allied health employers and employees regarding (1) allied health personnel shortages; (2) interest for multicredentialed allied health workers; (3) the educational preparation of rural multicredentialed allied health workers, and (4) factors...
