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,...

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...

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...

Evaluation of education libraries for teacher education accreditation

Creator:: Knittel, Marjorie C.
Abstract:: The purpose of this investigation was to examine the literature in education and library science to determine why standards for education libraries have not been realized, in the light of the specific criteria for other areas of teacher education accreditation. Educators and librarians in favor of strict standards for education...

Techno-economic analysis of algal lipid fuels

Creator:: Xiang, Xuwen
Abstract:: A techno-economic analysis (TEA) was performed to evaluate the technology, cost, and resource use for algal biofuel production based on today’s economics and technology. The basic goal of this study is to develop a model to calculate the mass and energy balances and costs to produce 10 million gal of...

Monte Carlo derived absorbed fractions in a voxelized model of a rainbow trout

Creator:: Hess, Catherine A.
Abstract:: The International Commission on Radiological Protection (ICRP) has modeled twelve reference animals and plants (RAPs) with simple geometric shapes to be used when estimating radiation dose to non-human biota (NHB). In recent years, there has been interest in creating more realistic models in order to better understand the radiation interactions...

Improvements in the dosimetric models of selected benthic organisms

Creator:: Caffrey, Emily Amanda
Abstract:: The International Commission on Radiological Protection (ICRP) has modeled twelve reference animal and plant (RAP) species using simple geometric shapes in Monte–Carlo (MCNP) based simulations. The focus has now shifted to creating voxel phantoms of each RAP to advance the understanding of radiation interactions in nonhuman biota. The work contained...

The economic impacts of sagebrush steppe wildfires on an eastern Oregon ranch

Creator:: Maher, Anna T.
Abstract:: The relative success of restoration practices on cheatgrass infested sagebrush steppe lands in the Great Basin can affect the probability of crossing an ecological threshold and have economic effects on cattle ranches using federal rangelands. Cheatgrass invasion implies an increase in the risk of fire, which in turn increases the...

Analysis of Culturally Derived Speleothems by INAA and ICP-MS, a Multi-Analytical Approach

Creator:: Nation, Humberto E.
Abstract:: Over the last two decades, archaeologists have documented the widespread ancient Maya practice of collecting cave formations (speleothems) from ritually important caves and transporting them to their settlements. Little is known about their specific uses within settlements, but it is hypothesized that these objects convey a degree of sanctity from...

Local and Global Explanations for Deep Image Classification via Structured Attention Graphs

Creator:: Shitole, Vivswan
Abstract:: Attention maps are popular tools of explaining the decisions of convolutional neural net-works (CNNs) for image classification. Typically, for each image of interest, a single attention map is produced, which assigns weights to pixels based on their importance to the classification. We argue that a single attention map provides an...

Fisheries Connectivity Networks to Measure the Adaptive Capacity of Small-Scale Fisheries in the Baja California Peninsula, Mexico

Creator:: Nomura, Keiko
Abstract:: Small-scale fisheries around the world are increasingly facing pressures from a range of environmental, economic, and social sources. In order to sustain the societal benefits of small-scale fisheries, it is imperative to understand how fishing communities adapt to disturbances. Fishermen often catch multiple different species as an adaptation technique because...

Proposed minimum mesh size for managing the common Chilean hake fishery

Creator:: Pavez Carrera, Patricio B.
Abstract:: An analysis was conducted to estimate the minimum mesh size for managing the common Chilean hake (Merluccius gayi) fishery. Secondary objectives were to establish the selective relationship between mesh size and fish length, to examine growth patterns and related parameters, and to estimate the critical age (or optimum size) at...
