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...

Kenward-Roger approximate F test for fixed effects in mixed linear models

Creator:: Alnosaier, Waseem S.
Abstract:: For data following a balanced mixed Anova model, the standard Anova method typically leads to exact F tests of the usual hypotheses about fixed effects. However, for most unbalanced designs with most hypotheses, the Anova method does not produce exact tests, and approximate methods are needed. One approach to approximate...

Assemblages of groundfish caught using commercial fishing strategies off the coasts of Oregon and Washington from 1985-1987

Creator:: Rogers, Jean Beyer
Abstract:: The groundfish trawl fishery operating off the coasts of Oregon and Washington 1985-1987 caught six major assemblages of species which could be treated as units in developing mixed-species management plans. Eighty-one percent of the tows observed on commercial vessels were consistently placed in one of the assemblage designations using three...

Kinematics and Dynamics of a Model Eastern-boundary Poleward Undercurrent

Creator:: Duran, Rodrigo
Abstract:: A carefully calibrated primitive-equation model from 41°N to 48°N is used to study the poleward undercurrent off the US west coast. Chapter 2 describes poleward flow over the slope from Eulerian and Lagrangian perspectives. The model is robust, in the sense of several characteristics being qualitatively consistent with observational and...

Magmatic processes beneath mid-ocean ridges : insights from mineral and glass chemistry in plagioclase ultraphyric basalts

Creator:: Lange, Amy E.
Abstract:: Prior to eruption at mid-ocean ridges, melts must travel through >6 km of crust from their origin in the mantle. The final composition of the melts is dependent on both the melting conditions and magmatic processes within the crust. While mid-ocean ridge basalt (MORB) glasses are commonly used to infer...

Postsecondary student consumerism : a national Delphi forecast of developments and articulation of policy options

Creator:: Franks, Robert Grover
Abstract:: The purpose of this research, expressed in two coequal parts, was: to establish a forecast of developments and an articulation of policy options vis-a-vis postsecondary student consumerism; and to determine if interest groups of experts differed significantly in their evaluations of the aforementioned developments and policy options. The Delphi technique...

Sex-role identity differences as a function of place of residence of male college students

Creator:: Whipple, Edward George
Abstract:: The purpose of this investigation was to determine whether sex-role identification differences among college students were related to place of residence, and if so, whether certain factors affect these differences. Six hypotheses were developed. The study sought to ascertain if sex-role identification is related to certain dimensions of peer association...

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...
