Predicting pore pressure response in in-situ liquefaction studies using controlled blasting

Creator:: Eller, James Michael
Abstract:: Originally used as a method to densify loose soils, controlled blasting has expanded its applicability to geotechnical engineering by becoming a research tool to physically generate liquefaction for full-scale in-situ tests, ranging from seismic performance of deep foundations to evaluating ground improvement techniques. Current methods used to design the blasting...

Structural investigations to understand the mechanisms of two proteins involved in sulfur chemistry : SsuE and cysteine dioxygenase

Creator:: Driggers, Camden McCullough
Abstract:: Sulfur is one of the six elements required during the early stages of the evolution of life, and enzymes involved in sulfur transfer and oxidation are increasingly being recognized as potential drug targets for antimicrobials as well as for therapies for cancer, neurodegenerative and inflammatory diseases. Bacteria are able to...

Early Selection for Improving Volume Growth in Coastal Douglas-fir Breeding Programs

Creator:: Ye, T. Z. and Jayawickrama, K. J. S.
Abstract:: Measurements on growth traits up to 41 years of age from 68 progeny sites in eight first-generation breeding zones of coastal Douglas-fir (Pseudotsuga menziesii [MIRB.] FRANCO var. menziesii) in the US Pacific Northwest were used to investigate age trends of genetic parameters and to determine optimum age of selection. Heritabilities...

Quantification of Copper Speciation in Pulp and Paper Wastewater and Implications for the Biotic Ligand Model

Creator:: Mitzel, Joseph M.
Abstract:: The purpose of this research was to measure the copper-binding behavior of Dissolved Organic Matter (DOM) contained in Pulp and Paper (P&P) wastewater effluent and evaluate the Biotic Ligand Model’s (BLM) ability to quantify copper speciation in P&P influenced waters. A copper ion selective electrode was used to measure copper...

Evaluating Biochar for the Sustainable Treatment of Heavy Metals in Stormwater: Characteristics, Mechanisms, and Barriers

Creator:: Burch, Sarah
Abstract:: Heavy metals, such as copper, zinc, and cadmium, are ubiquitous in stormwater and potentially toxic to aquatic organisms at low concentrations. Removal of heavy metals contamination by conventional treatment is expensive and does not always reduce metals concentrations low enough to ensure safety of all aquatic species. This research seeks...

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...

Quantification of C60 Particle Characteristics in Environmentally Relevant Aqueous Systems

Creator:: Adlong, Michelle R.
Abstract:: The production of the fullerene C60 and its emerging applications in consumer products imply its ultimate release to the environment. Due to the molecule’s relative novelty, the aqueous characteristics of C60 have not been fully assessed, though it may potentially harm human or ecological health. C60 is highly insoluble in...

Development of traceable metal oxide nanoparticles for examining environmental fate and transport

Creator:: Rowbotham, Brian
Abstract:: The fate and transport of engineered nanoparticles (ENPs) such as titanium dioxide (TiO₂) are of concern due to their increasing use in consumer products. Although analytical methods for detection and quantification of ENPs in environmental matrices are being developed, these methods are difficult, time consuming, and not easily validated for...

Interactions between natural organic matter and gold nanoparticles stabilized with different organic capping agents

Creator:: Stankus, Dylan Paul
Abstract:: The adsorption of natural organic matter (NOM) to the surfaces of natural colloids and engineered nanoparticles is known to strongly influence, and in some cases control, their surface properties and aggregation behavior. As a result, the understanding of nanoparticle fate, transport and toxicity in natural systems must include a fundamental...

Characterization of Biochar for Use in Treating Copper (II) Polluted Stormwater

Creator:: Gerould, Joy-Marie Danielle
Abstract:: Recent studies have discovered that salmon, specifically juvenile Coho Salmon, have their olfactory senses inhibited by the presence of low concentrations of copper concentrations at very low concentrations. Much of this copper is deposited on roadways by car brake pads during their use. The copper is carried with stormwater into...
