Creator:: Martens, Jacob L.
Abstract:: These essays are an attempt to rebuild memories that explore the nature of work and family. They explore how work knocks against the joints of the body and against the joints between family members, and, as time passes, how the next generation inherits the family line of work only to...

Inhibition of Organohalide-Respiring Bacteria by Carbon Tetrachloride and Chloroform

Creator:: Ehret, Emma L.
Abstract:: Despite decades of cleanup efforts, chlorinated solvents are some of the most common groundwater and subsurface contaminants of the industrialized world. These compounds include chlorinated ethenes (CEs) such as trichloroethene (TCE) and chlorinated methanes (CMs) such as carbon tetrachloride (CT). Dehalococcoides mccartyi belongs to a class of microorganisms called organohalide-respiring...

Experimental demonstration and modeling of aerobic cometabolism of 1,4-dioxane by isobutane-utilizing microorganisms in aquifer microcosms

Creator:: Rolston, Hannah M.
Abstract:: 1,4-dioxane, a probable human carcinogen at low (< 1ppb) concentrations, has emerged as a groundwater contaminant due to its historical use as a stabilizer for the chlorinated solvent 1,1,1-trichloroethane. Aerobic cometabolism, the use of a primary substrate to induce the production of microbial enzymes that fortuitously degrade other compounds, is...

Anaerobic Dehalogenation of Trichloroethene by Encapsulated Dehalococcoides mccartyi

Creator:: Lukens, Eileen P.
Abstract:: Chlorinated aliphatic hydrocarbons (CAHs) like trichloroethene (TCE) were mostly used to replace drying cleaning fluids which contained hydrocarbons like benzene, and were highly flammable. Through improper disposal, storage, and spills, TCE and its downstream products, like cis-dichloroethene (cDCE) and vinyl chloride (VC), leached into groundwater and threaten human and environmental...

Rhyolitic Melt Production in the Midst of a Continental Arc Flare-Up - The Heterogenous Caspana Ignimbrite of the Altiplano-Puna Volcanic Complex of the Central Andes

Creator:: Lewis, Charles T.
Abstract:: The ~5 km3, 4.54 to 4.09 Ma Caspana Ignimbrite of the Altiplano-Puna Volcanic Complex (APVC) of the Central Andes records the eruption of an andesite and two distinct rhyolitic magmas. It provides a unique opportunity to investigate the production of silicic magmas in a continental arc flare-up, where small volumes...

Kinetic analysis of the aerobic degradation of chlorinated ethenes by the mycobacterium ELW-1 and chlorinated ethanes and ethenes by rhodococcus rhodochrous ATCC® 21198™

Creator:: Rich, Stephanie L.
Abstract:: Bioremediation of chlorinated ethenes by the augmentation of contaminated soils with microorganisms is a proposed method of reducing contaminant concentrations in groundwater. To determine the viability of using ELW-1 or R. rhodochrous for groundwater remediation, kinetic analyses of transformation rates must be performed. The focus of this research was to...

Inhibition of the ammonia oxidizing bacteria Nitrosomonas europaea by the emerging contaminant triclosan

Creator:: Hughes, Jamie L.
Abstract:: Identifying the inhibition of ammonia oxidizing bacteria (AOB) by emerging organic contaminants is crucial due to the importance of AOB in wastewater treatment, the widespread use of antibacterial agents such as triclosan (TCS) in consumer products, and the sensitivity of N. europaea to inhibitors. Triclosan inhibition of nitrification by AOB...

Including Elementary Students in the Functional Behavior Assessment – Behavior Intervention Process

Creator:: Place, Samantha L.
Abstract:: The present study seeks to develop a functional behavior assessment interview (FBAI) that would allow elementary aged students to participate in the assessment process. In particular, the assessment will address if elementary students are able to accurately predict the causes of their problem behaviors and identify when they are likely...

The Empathetic Melancholy of Celluloid Decay

Creator:: Schuster, Andrea L.
Abstract:: As digital video pushes celluloid film further into obsolescence, many artists and viewers mourn the loss of what they consider a more organic medium. Photochemical film is subject to decay due to variables of care and the inevitability of time, and film’s embodied vulnerabilities are similar to those of the...

Characterization of ecosystem structure and function recovery within the NOAA MOC-P mitigation basin, Newport, Oregon

Creator:: Lewis, Nate S.
Abstract:: Seagrass ecosystems are considered some of the most productive coastal habitats in the world. One such seagrass within estuaries of the Pacific Northwest, Zostera marina (eelgrass), is recognized to be an ecosystem engineering species that provides many important ecosystem functions and services. In 2010, construction of the National Oceanic and...
