Demonstration of a permeable barrier technology for the in-situ bioremediation of pentachlorophenol contaminated groundwater

Creator:: Cole, Jason David
Abstract:: A pilot scale demonstration of a biological permeable barrier was conducted in a pentachlorophenol-contaminated aquifer at a wood preserving facility. A permeable reactor was constructed to fit within a large diameter well. Arranged in series, a cylindrical reactor 24" x 36" (0.61 x 0.91m) (diameter x height) was partitioned to...

Politicized Collective Illness Identity and Boundary-Spanning in Western Montanan Community Health Workers: An Ethnographic Study

Creator:: McQuillan, Kindra
Abstract:: Background: Against global health disparities and a shortfall of medical personnel, community health workers (CHWs) promise a solution based in lived experience and connection to the health system. To address global and upstream health determinants, CHW programs engage the perspectives of both the workers they employ and the communities they...

Exploring how Secondary Agriculture Teachers Reconcile the Competing Demands of the Profession

Creator:: Traini, Haley Q.
Abstract:: The purpose of this study was to explore the lived experiences of secondary agriculture teachers as they reconcile the competing demands of the profession in the social landscape of School-Based Agricultural Education. Previous literature about the agriculture teacher shortage problem revealed opportunities for research to utilize qualitative approaches and alternative...

Uranium and technetium bio-immobilization in intermediate-scale physical models of an in situ bio-barrier

Creator:: Michalsen, Mandy M.
Abstract:: Metal and hydrogen ion acidity and extreme nitrate concentrations typical of Department of Energy (DOE) legacy waste sites pose formidable challenges to successful implementation of in situ bio-immobilization. Intermediate-scale (~ 2.5 m), flow through models of an in situ bio-barrier were constructed to investigate U and Tc removal from groundwater...

Quantitative, multi-spectral, light-transmission imaging of colloid transport in porous media at the meso scale

Creator:: Kraft, Erika Lorna
Abstract:: Colloids, particles smaller than ten microns in diameter, are ubiquitous in the subsurface. Colloids have an effect on the transport of contaminants that bind to their surfaces, and can reduce the permeability of aquifer materials through deposition. Some microorganisms, including pathogens, are also transported in the subsurface as colloids. The...

The Influence of Entrepreneurs’ Physical and Cognitive Traits on Entrepreneurial Outcomes

Creator:: Farah, Nusrat
Abstract:: The dissertation examines the effect of two separate yet significant individual level factors—physical and cognitive traits—on entrepreneurial outcomes. The physical factor on which the dissertation focuses is the entrepreneur’s vocal cues and the cognitive traits that the dissertation investigates are the entrepreneur’s goal orientation and his/her ability to take perspectives....

Analysis of Carbon-14 Transport from a Contaminated Groundwater Source

Creator:: Napier, Jonathan Bamberger
Abstract:: Radioecology observes the movement of radioactive isotopes throughout the environment. For radioecology, locations of study are limited to areas accidentally contaminated from a number of sources. The Chalk River Laboratories of Atomic Energy of Canada Limited have stored low level waste since the mid 1940s. In certain instances, the wastes...

Reliability-based Serviceability Limit State Design Procedures for Shallow Foundations

Creator:: Huffman, Jonathan C.
Abstract:: Reliability-based geotechnical foundation design focusses on soil and structure analysis that meets necessary safety, performance and/or serviceability criteria, calibrated based on probabilistic analyses and an accepted level of risk. As the civil engineering community seeks to better harmonize geotechnical and structural design methodologies, reliability-based design is being incorporated more into...

Numerical simulation of anaerobic reductive dechlorination of CAHs in continuous flow systems

Creator:: Mustafa, Nizar Ahmad
Abstract:: Halogenated organic compounds have had widespread and massive applications in industry, agriculture, and private households, for example, as degreasing solvents, flame retardants and in polymer production. They are released to the environment through both anthropogenic and natural sources. The most common chlorinated solvents present as contaminants include tetrachloroethene (PCE, perchloroethene)...

Exploring the System-Based Influences on Professional Goals of Early Career Agriculture Teachers in California: A Phenomenological Approach

Creator:: Ermis, Grant L.
Abstract:: Agriculture teachers, in comparison to other high school teachers, work in more varied and demanding work environments (Terry & Briers, 2010; Torres, Ulmer, & Aschenbrener, 2008). The body of literature studying the impacts of more varied and demanding work environment on early career agriculture teachers (ECATs) is commonly limited to...
