The seismic vulnerability of sheet pile walls

Creator:: McCullough, Nason J.
Abstract:: The seismic performance of port structures has been well documented following recent earthquakes, and indicates that port structures are highly susceptible to earthquake-induced damages. These damages are primarily due to soil liquefaction and the associated ground failures. Sheet pile bulkheads provide vital intermodal and lifeline transportation links between water-side and...

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...

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...

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...

Analytical determination of copper speciation in Oregon highway runoff

Creator:: Sprick, Matthew S.
Abstract:: Low concentrations of dissolved copper have been shown to adversely affect the olfactory system of endangered salmonids, impairing their ability to avoid predators and likely increasing predation. It is believed that only the free ionic (Cu2+ free) and weakly complexed forms are bioavailable to organisms; these forms typically account for...

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...

Evaluation of Apatite II™ for removal of copper and zinc from highway stormwater runoff : laboratory and field experiments

Creator:: Provolt, Justin J.
Abstract:: Current best management practices (BMPs) for stormwater treatment are not able to adequately remove heavy metals to levels which do not adversely affect aquatic life. Copper is commonly found in highway stormwater runoff, with the primary source being brake pad wear. Copper is of particular concern due to inhibitory effects...

Heteroaggregation of gold nanoparticles with model colloids and the influence of environmental aqueous chemistry

Creator:: Pike, Daniel J.
Abstract:: Nanoparticles are becoming increasingly important in numerous technological fields but evidence shows that they can be toxic to many organisms. To predict their fate and transport in the environment, nanoparticle attachment to naturally occurring colloids must be examined. This study investigated citrate-capped gold nanoparticle (Cit-AuNP) heteroaggregation with two model colloids...
