The Genomic Capabilities of Microbial Communities Track Seasonal Variation in Arctic Lagoons

Creator:: Baker, Kristina D.
Abstract:: The lagoons spanning Alaska’s Beaufort Sea coast provide a unique habitat for arctic wildlife. These lagoons and the food webs they support face extreme seasonality with nine months of ice cover followed by a spring thaw that pulses a large amount of freshwater and nutrients into the lagoons. Bacteria link...

A comparative study of lowpass continuous-time delta-sigma modulators with pulse-shaped DACs

Creator:: Fang, Jie
Abstract:: Recently, continuous-time ΔΣ modulators are appearing increasingly often in both the literature and the marketplace due to their features of inherent antialiasing and relaxed requirements for opamp and so on. However, several nonideal factors such as clock jitter, excess loop delay, inter-symbol interference and so on, degrade the SNR performance...

Microbial Electrolysis Cells for the Production of Hydrogen Gas : Evaluation of Internal Resistance and Design for Scale-Up

Creator:: Miller, Andrew G.
Abstract:: Modification of microbial electrolysis cells (MECs) by altering the sizes of the anode and the cathode, or their interaction with the liquid stream affects the performance of the MEC, but it remains difficult to quantify how much each change will contribute to the overall performance. Through this study, a method...

Structure-Property Relationships of Supported Palladium and Rhenium Oxide for the Alkane Rearrangement of Hydrocarbons and Deconstruction of Polyethylene via Tandem Dehydrogenation and Olefin Metathesis

Creator:: Moore, Selena C.
Abstract:: The rapid accumulation of plastic waste in landfill, waterways and oceans is becoming a critical problem, one that current recycling technologies are not capable of solving. Recent proposed approaches in the depolymerization of waste plastics employ an Olefin-Intermediate Process (OIP), where feedstocks like polyolefin plastics are ‘activated,’ producing an olefin...

Underneath Our Feet: A Critical Discourse Analysis of an Underground Museum Tour

Creator:: Sokoloski, Taryn Leigh
Abstract:: This study explores an underground museum located in Pendleton, Oregon. Using the method of Critical Discourse Analysis, I identify the ways Whiteness and Chinese as “the Other” are visually and verbally depicted. This study uses a qualitative approach to identify the ways both groups are presented on the tour. The...

Influence of Processing Parameters on the Inactivation of Salmonella spp. During the Cooking Step of Jerky Production Using a Commercial-Scale Dehydrator

Creator:: Minarsich, Joey
Abstract:: United States Department of Agriculture-Food Safety and Inspection Service (USDA-FSIS) guidelines for beef jerky processing support producers' ability to satisfy the performance standard requirements for achieving a 5-log reduction in Salmonella and E. coli O157:H7. The first compliance guide for jerky processors was created in response to several Salmonella outbreaks...

Multidisciplinary Approach to Evaluate the Effect of Plant Growth Promoting Rhizobacteria (PGPR) on Soil Microbiota and Quality of Strawberries

Creator:: Nam, Jun Haeng
Abstract:: Oregon strawberries are known for their high quality, intense flavor, sweetness, and rich red color. With optimal weather conditions, including rainy and mild seasons, Oregon has one of the best strawberry farming environments. Amongst the factors for a suitable strawberry farming environment, soil significantly influences strawberry growth and quality. The...

Evaluating the Sustainability of an Advanced Biofuel Using Attributional and Consequential Life Cycle Assessments

Creator:: McDaniel, Allexander M.
Abstract:: Attributional and consequential life cycle assessments are useful in evaluating the environmental impacts of a process, product, or decision. Both types of life cycle assessments differ however in their scope and their ability to answer specific questions. In order to fully understand and compare the environmental impacts of a sugarcane...

The effects of engineered coatings and natural organic matter on nanoparticle aggregation

Creator:: McDowell, Shannon A.
Abstract:: In order to better predict the aggregation state of nanomaterials, the factors that influence aggregation must be understood. The combined effects of natural and engineered coatings have been shown to factor into nanoparticle aggregation behavior in preliminary research. In this study, aggregation behaviors of gold nanoparticles with two different engineered...

Synthesis and characterization of zero valent iron nanoparticles

Creator:: Coussens, Nathaniel J.
Abstract:: Synthetic methods for the preparation of magnetic nanocomposites with improved high frequency (into the GHz range) performance over conventional magnetic materials were examined. The most successful work involved synthesis of nanocrystalline zero valent iron particles (nc-Fe) through a reverse micelle method. Here, aqueous Fe(II) solution micelles formed using cetyl trimethylammonium...
