Ecosystems at Risk: The Contribution of Ecosystem Approaches to Fisheries to Identify Problems and Evaluate Potential Solutions

Creator:: Christensen, Villy, Villanueva, Maria Concepcion, and Aiken, Karl A.
Abstract:: The wide expanse of the sea, the inter-linkages among, and the productivity of its resources have until recently led most researchers to consider it unrealistic that humans could have more than local impact on marine ecosystems and their biodiversity. This perception is changing, however, as more evidence of the scale...

The biosynthesis of ethylene from methionine in Saccharomyces cerevisiae

Creator:: Jones, Paul Aikens
Abstract:: Methionine metabolism, leading to the biosynthesis of ethylene in Saccharomyces cerevisiae does not appear to involve S-adenosylmethionine (SAM) and aminocyclopropanecarboxylic acid (ACC), based on the lack of ethylene synthesis when both SAM and ACC were incubated in the presence and absence of cells. Thus, the mechanism leading to the formation...

Development and administration of a scale to measure the computer attitude of preservice and inservice teachers at the elementary school level

Creator:: Evans, Anantaporn Disatapundhu
Abstract:: The purpose of this study was to: (a) develop a comprehensive plan consisting of a series of logical steps based upon recommendations derived from psychometric, measurement, and research literature and utilize the plan to develop a Likert-type scale to provide valid and reliable measures of the attitude of preservice and...

The influence of program context intensity: an examination of television advertising during war news

Creator:: Aiken, K. Damon and Malkewitz, Keven
Abstract:: Advertisers often shy away from graphic, emotionally-charged programming under the assumption that the programming intensity will impair viewer recall, as well as negatively influence viewer perceptions. This paper empirically investigates this assumption and finds that advertisers are at least partially mistaken. We utilize war news programming as a fitting emotional...

Thermal hydraulic analysis of a U-tube steam generator in a pressurized water reactor

Creator:: Chadly, Peter Brent
Abstract:: A vital safety concern in the analysis of nuclear power reactors is the thermal hydraulic behavior of the reactor coolant system under steady state and transient conditions. The goal of this study has been to develop an appropriate model for the U-tube type steam generators in a typical pressurized water...

A RETRAN model for a hypothetical steam line break occurring at low power operation of the Trojan Nuclear Plant

Creator:: Jensen, Peter John
Abstract:: The goal of this study is the modeling of a postulated break of the steam line at the containment penetration of the Trojan Nuclear Plant which is owned and operated by Portland General Electric. To perform this modeling, the RETRAN computer code package was utilized. RETRAN is designed to provide...

Karl Popper's Organon and the world's fisheries; fish stock assessment as a pseudoscience, an inductivism that can bear no fruit

Creator:: Corkett, Christopher
Abstract:: If a scientist can predict the weather (poorly) Why cannot he predict fish yields (yet more poorly)? – a clerihew by Chris Corkett. Recent long term historical studies of commercial fisheries have pointed to a well established pattern of overfishing. Under the principle of transference – what is true in...

Development and implementation of an improved formulation of the momentum balance for a Once Through Steam Generator transient model

Creator:: Luo, Shyr Tung
Abstract:: A detailed formulation of the momentum equation including the Baroczy model for two phase friction is presented in this thesis. Numerical techniques for solving this equation along with the remainder of the describing equations are also presented. This model has been incorporated into an existing thermal hydraulic code for simulating...

The evaluation of the field vane shear strength analysis of the Glen Aiken creek embankment failure

Creator:: Clarke, James Dennis
Abstract:: A post-failure investigation of a highway embankment constructed over organic and sensitive subsoils was made with a series of field vane tests. The results indicated that the embankment was quite stable, and, therefore, the reliabilities of both the Φ = 0 slip-circle analysis and the field vane results seemed to...
