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...

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...

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...

Environmental Regulations Reconsidered : Identifying Incentives and Barriers to Environmental Performance

Creator:

Craig, Kathleen D.

Abstract:

Attention has been drawn to the observation that environmental benefits under the current regulatory approaches are diminishing with respect to increased pollution control costs. Regulators have begun to appreciate that while environmental gains can still be achieved under the current command and control system, the most significant environmental gains have...

The effects of nail bending-yield stress and biological deterioration on the cyclic performance of shearwalls

Creator:

Anderson, Erin N.

Abstract:

Key parts of the lateral force resisting system in wood-frame buildings are the shearwafls and the connections. The connections in wooden buildings are the primary source of ductility and energy dissipation; these are essential properties when buildings are exposed to lateral forces, such as wind and earthquakes. Shearwall design is...

Biodegradation of methyl tert-butyl ether (MTBE) and its breakdown products by propane and iso-pentane grown Mycobacterium vaccae and Graphium sp. : cometabolism, inhibition, kinetics, and modeling

Creator:

Martínez-Prado, Maria Adriana

Abstract:

Mycobacterium vaccae JOB5 and Graphium sp. were studied to evaluate their ability to cometabolize methyl tert-butyl ether (MTBE) and its metabolites after growth on two different alkanes, propane and iso-pentane. Both cultures were capable of cometabolizing MTBE and the metabolites, tert-butyl formate (TBF) and tert-butyl alcohol (TBA). MTBE, TBF, and...

Changes in hyporheic exchange flow following experimental large wood removal in a second order, low gradient stream, Chichagof Island, AK

Creator:

La Nier, Justin

Abstract:

Hyporheic Exchange Flow (HEF) is driven by head gradients defined by the hydro-topography of the stream surface, which is controlled by the particular geomorphology of the stream. We quantified the impact of large wood, which typically exerts a strong control on stream morphology, on HEF in a second order, low...
