Aerobic biotransformation of chlorinated aliphatic hydrocarbons by a benzyl alcohol grown mixed culture : cometabolism, mechanisms, kinetics and modeling

Creator:: Tejasen, Sarun
Abstract:: The aerobic transformation of TCE and cis-DCE by a tetrabutoxysilane-grown microorganism (Vancheeswaran et al., 1999) led to the investigation of novel substrates, including benzyl alcohol, for promoting cometabolism. The culture grew on carboxylic compounds and alcohols, but did not grow on formate, methanol, methane, propane, butane, ethylene, benzene, toluene, or...

Strain distribution in OSB and GWB in wood frame shear walls

Creator:: Sinha, Arijit
Abstract:: The overall goal of this study was to gain an insight into the load sharing aspect between oriented strand board (OSB) and gypsum wall board (GWB) in shear wall assembly during racking load. More specifically the objectives of the study were to: (1) evaluate qualitatively the load sharing between OSB...

Simple Moving Averages: A Ten-Year Test

Creator:: Wilder, Eric M.
Abstract:: The intent of this thesi s is to prove whether or not simple moving averages can be used to predict the future price performance of stocks and outperform the buy-and-hold method of investing in the stock market. The importance of this research is that if moving averages can predict future...

Modeling shallow-water hydrodynamics : rotations, rips, and rivers

Creator:: Long, Joseph W.
Abstract:: Hydrodynamic models are used as a diagnostic tool to understand the temporal variability of shallow-water processes that are difficult to completely resolve with traditional field measurements. For all simulations, modeled quantities are qualitatively or quantitatively compared with available measurements to gain confidence in conclusions derived from the modeled results. In...

Social capital in engineering education

Creator:: Brown, Shane
Abstract:: A theoretical argument is presented to suggest that engineering curriculum be designed to develop social capital. Additionally, the value of social capital in the retention of students in the College of Engineering, and the development, role, and value of social capital in an electrical engineering laboratory is evaluated. Data collected...

Numerical modeling of full-coupled fluid-structure interaction

Creator:: Yuk, Dongjun
Abstract:: A numerical model for the simulation of fully-coupled fluid-structure interaction is developed in this study. In modeling the fluid, the Reynolds Averaged Navier-Stokes equations are solved for an incompressible viscous fluid field and a k-ε model is employed for turbulence computations. Hydrodynamic forces obtained by the integration of the fluid...

The effects of land use on stream nitrate concentrations : from the catchment scale to the regional scale

Creator:: Poor, Cara J.
Abstract:: This work furthers the understanding of processes occurring in catchments that affect stream nitrate concentrations using two different approaches: a temporally intensive case study of three headwater catchments with varying land use (through storm event monitoring) and a spatially intensive study on the regional scale (through statistical modeling) of 1st-4th...

Reducing sediment production from forest roads during wet-weather use

Creator:: Toman, Elizabeth Myers
Abstract:: Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids. The goal of this work was to investigate turbid runoff during wet-weather...

Multi-metal equilibrium sorption and transport modeling for copper, chromium, and arsenic in an iron oxide-coated sand, synthetic groundwater system

Creator:: Osathaphan, Khemarath
Abstract:: The mixed metal compound, Chromated Copper Arsenate, or CCA, has been widely used as a wood preservative. The metal ions in CCA, CrO²⁻₄, Cu²⁺, and AsO³⁻₄, have been found in contaminated surface and subsurface soils and groundwater nearby some wood preservative facilities and nearby wood structures. Iron oxides are a...

Electron donor and chlorinated ethene effects on activity and community composition in anaerobic reductively dechlorinating consortia

Creator:: Sabalowsky, Andrew R.
Abstract:: This research focused on anaerobic transformation of trichloroethene (TCE), a groundwater contaminant. The mixed anaerobic Evanite culture (EV) was studied to determine community behavior and composition responses to different electron donors and chloroethene electron acceptors. The potential toxicity from high concentrations of TCE and its daughter product cis-1,2-dichloroethene (cDCE) was...
