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...

Depth-dependence of surf zone eddies : a study at Duck, NC

Creator:: Aiken, Rebecca A.
Abstract:: Surf zone eddies (f < 0.01 Hz) are important in nearshore mixing, shoreline erosion, the distribution of pollutants, and ecological processes, such as offshore transport of larvae. Surf zone eddies have traditionally been treated as two-dimensional features with horizontal length scales larger than the local water depth. Studies by Lippmann...

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...

Karl Jordan : a life in systematics

Creator:: Johnson, Kristin Renee
Abstract:: Karl Jordan (1861-1959) was an extraordinarily productive entomologist who influenced the development of systematics, entomology, and naturalists' theoretical framework as well as their practice. He has been a figure in existing accounts of the naturalist tradition between 1890 and 1940 that have defended the relative contribution of naturalists to the...

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...

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...

Properties of hydrogels for immobilization of bacteria in a commercial microfluidic dioreactor

Creator:: Weymann, Davis
Abstract:: Current technological shortcomings limit the economic viability of capturing and utilizing small sources of methane. The development of a reactor to overcome these limitations would unlock economic opportunity and incentivize reduced methane emissions. A microfluidic bioreactor containing immobilized methanotrophs has the potential to overcome these limitations by profitably converting small...

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...
