An Empirical Study of Work-zone Safety and Mobility Using Surveys and Anonymous User Generated Trip Information

Creator:: Fiawoyife, Kenneth K.
Abstract:: The two primary considerations for highway work-zones are its effect on commuter mobility and worker safety which are often spoken of together. However, it must be noted that they often conflict with each other. For example, traffic control plans that reduce travel speed in work-zones improve both commuter and worker...

Interactions between microbial dynamics, water flow, and solute transport in unsaturated porous media

Creator:: Yarwood, Rockie R.
Abstract:: Bioremediation in the vadose zone is unpredictable because of poor understanding of factors influencing microbial growth in this environment. A lab-scale experimental system was developed to examine, noninvasively, interactions between microbial growth, water flow, and solute transport in unsaturated porous media. Measurements of microbial colonization, and its impact on hydrology,...

The identification and quantitation of complex polycyclic aromatic hydrocarbon mixtures in environmental samples using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry

Creator:: Manzano, Carlos A.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants and are mostly products of the incomplete combustion of organic material. PAHs are often found in environmental samples as a complex mixture of isomers. In addition, the same sources that produce complex PAH mixtures also produce other poorly characterized mixtures of organic compounds,...

The atmospheric chemistry of particulate-bound polycyclic aromatic hydrocarbons : concentration, prediction, laboratory studies, and mutagenicity

Creator:: Jariyasopit, Narumol
Abstract:: The trans-Pacific atmospheric transport of particulate matter (PM)-bound polycyclic aromatic hydrocarbons (PAHs) to remote sites in western North America has been well documented and has triggered research questions regarding to atmospheric transformation of PM-bound PAHs and the potential impacts on human health from their inhalation exposure. In this dissertation, field...

Immune responses of juvenile chinook salmon (Oncorhynchus tshawytscha) to p,p-̓DDE and tributyltin

Creator:: Misumi, Ichiro
Abstract:: In this thesis, we examined the effects of the exposures to anthropogenic pollutants on the fish, primarily juvenile chinook salmon, immune system using newly and recently developed immune assays. In addition, we developed a new assay for measuring immunocompetence of fish. In the first chapter, the Alamar Blue assay was...

Bulldozer blades and colliding submarine mountain chains : constraints on central Oregon convergent margin tectonics from magnetics and gravity

Creator:: Fleming, Sean W.
Abstract:: Magnetic and gravity modelling was completed along two E-W transects offshore central Oregon. These models indicate that the backstop-forming western edge of the Siletz terrane has a seaward dip of approximately 40° to 49° at 44°48'N, shallowing to ~28° at 44°1 1 'N. This is a well-determined result, given available...

Monitoring redox conditions with redox indicators during microbial reductive dechlorination in microcosms and bioaugmented columns

Creator:: Ruiz-Haas, Peter A.
Abstract:: New methods, sensors, and devices based on redox indicators were developed to monitor redox conditions in anoxic and anaerobic laboratory systems and the subsurface environment. The primary application was monitoring redox conditions during the dechlorination of tetrachioroethene (PCE) to ethene (ETH) in packed columns and microcosm bottles containing an enriched...

Trace analysis of halogenated polycyclic aromatic hydrocarbons from an electronic waste recycling area and Guangzhou, China

Creator:: Gonzales, Leah R.
Abstract:: Halogenated Polycyclic Aromatic Hydrocarbons (X-PAHs) are ubiquitous contaminants that are thought to be generated by processes such as chemical industries and incomplete combustion, including waste incineration and electronic waste (e-waste) burning. X-PAHs are a concern for environmental and human health because they are toxic, mutagenic, and are expected to be...

Current Drug Policies in the United States : Using Research to Inform Policy

Creator:: Beathard, Candice
Abstract:: Drug policies in the United States are rapidly changing at the state and national level paralleling a shift in drug culture from a societal perspective. This dissertation addresses current public health policy topics with a focus on three recent drug policies. As of 2015, medical cannabis is legal in 23...

Tandem mass spectrometric analysis of protein and peptide adducts of lipid peroxidation-derived aldehydes

Creator:: Wu, Jianyong
Abstract:: The adduction of proteins and other biomolecules by electrophilic lipid peroxidation products such as 4-hydroxy-2-nonenal (HNE), 4-oxo-2-nonenal (ONE), malondialdehyde (MDA) or acrolein (ACR) is thought to be an initiating and/or propagating factor in the pathophysiology of several diseases such as atherosclerosis, diabetes, Alzheimer's, Parkinson's and other age-related disorders. The identification...
