Physiological and biochemical characteristics of two cultivars of tall fescue (Festuca arundinacea Schreb.) under different environmental conditions

Creator:: Fino, Antonio Carlos
Abstract:: Two cultivars of tall fescue (Festuca arundinacea Schreb.) with contrasting growth habits were studied under field and growth chamber conditions. Fawn, an established cultivar since 1964, and TFM, an experimental line, were observed to grow better during spring and fall months respectively, in the field. Different temperature regimes of 10/4,...

Decomposing Revenue Efficiency in Fisheries

Creator:: Alvarez, Antonio and Arias, Carlos
Abstract:: The estimation of production frontiers using revenue as the dependent variable is very common in fisheries research since in multi-species fisheries boats catch several species and their output must be aggregated somehow. The objective of this paper is to decompose revenue efficiency into two components, one due to quantities and...

Rapid endangered species assessment : a novel approach to improve extinction risk assessments in poorly known species

Creator:: Bianchi, Carlos A.
Abstract:: The number of endangered species is rapidly increasing while paucity of adequate information and resources delays establishment of conservation actions. The IUCN’s listing system is insufficient to determine conservation priorities and many species lack information even to be evaluated (i.e., “data deficient”). Here I proposed and tested the Rapid Endangered...

Survival Assessment, Inactivation Kinetics Models, and Farm-to-Table Quantitative Risk Analysis of Food Pathogens

Creator:: Deng, Kai
Abstract:: About 48 million cases of Foodborne illnesses (FBIs) are estimated to occur every year in the US. These are diseases caused by contamination of foods with bacteria, viruses, protozoa, parasites and toxic chemicals. Clostridium difficile infections (CDIs) are an important health-care and community associated problem. Since C. difficile spores have...

Impact of parameter variability on the food process engineering calculations required for safety, quality and shelf-life estimations

Creator:: Chotyakul, Nattaporn
Abstract:: Quantitative procedures were developed to determine the effect of variability in the model parameters required for the estimation of microbial shelflife and thermal processing time. Monte Carlo simulations combined with these predictive models were implemented in Microsoft Excel™. In the first study, predictive models were used for shelf-life predictions based...

Effect of molecular conformation on the surface properties of polyelectrolyte solutions : xanthan gum model studies

Creator:: Young, San Land
Abstract:: A commercially important polyelectrolyte, xanthan, was chosen for a systematic analysis of the relationship between molecular conformation and surface properties. In the first study the effects of ionic strength, xanthan concentration and temperature on the xanthan molecular conformation were investigated by potentiometric titration. The effects of the same factors and...

Reasons Behind the Low Enrollment of Women in Computer Science

Creator:: Schneider, Ashley R.
Abstract:: Over the past few decades, the ratio of women to men in many traditionally maledominated fields has become much more equal. However, in science, technology, engineering, and math (STEM) fields the ratio has not improved at the same rate. In computer science the ratio is still very uneven. Today women...

A comparison of psychological characteristics of standout police officers and Oregon Police Academy trainees

Creator:: Stevenson, Carl W.
Abstract:: Police officers are frequently viewed as being unable to perform the duties assigned to them by society. Criticism has focused on inappropriate reaction to social unrest and an inability to control crime. Improving the selection process of police officers has been proposed as an appropriate means of improving police officer...

Long-term Effects of Vegetation Management on Biomass Stock and Aboveground Net Primary Productivity of Four Coniferous Species in the PNW

Creator:: Flamenco, Herman N., Jr.
Abstract:: Forest vegetation management (FVM) is an important component of reforestation in the Pacific Northwest (PNW). Several studies have demonstrated the benefits of vegetation management on planted conifer growth and survival. However, few reports have been published on the long-term effects of FVM treatments on total ecosystem biomass accumulation and aboveground...

An Investigation of the Effects of Merge Conflicts on Collaborative Software Development

Creator:: Brindescu, Caius
Abstract:: Merge conflicts have long plagued software development. With larger and more dispersed teams comes greater risk of developers working on the same code at the same time. While merge conflicts are known to be painful, their exact impact on software is still largely unknown. Are merge conflicts an isolated problem,...

Monte Carlo analysis of the product handling and high-pressure treatment effects on the Vibrio vulnificus risk to raw oysters consumers

Creator:: Serment-Moreno, Vinicio, Deng, Kai, Wu, Xulei, Su, Yi-Cheng, Fuentes, Claudio, Torres, J. Antonio, and Welti-Chanes, Jorge
Abstract:: A Monte Carlo procedure considering the variability in oyster handling from harvest to raw consumption estimated reductions in the number of Vibrio vulnificus induced septicemia cases achieved by high-pressure processing (HPP). The calculations yielded pathogen load distributions in raw oysters from harvest to consumption. In the warm season, 2-6 min...
