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...
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...
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 (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...
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...
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...
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...
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...
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...
