Assessment of Bioenhanced Back Diffusion and Reductive Dehalogenase Gene Abundance in an Aquifer Cell Packed with Heterogenous Soils 

Cothran, Spencer (2023-04-26)
Remediation of chlorinated ethenes can be challenging at complex contaminated sites with low permeability soils acting as secondary source zones due to back diffusion of adsorbed contaminant mass. To better understand how ...

Assessment of Geochemical Reactivity in Geologic CO2 Utilization and Storage Systems 

Iloejesi, Chidera (2022-08-08)
Increasing atmospheric carbon dioxide concentration is a consequence of increasing energy consumption. As a result, developing ways to manage excess CO2 emissions has become a vital concern to avert the exacerbating effects ...

BEHAVIOR AND CAPACITY OF THERMALLY RESTRAINED MOMENT FRAME MEMBERS DURING COMPARTMENT FIRE 

Chinivar, Supriya Nagraj (2021-07-27)
In the event of a fire hazard, structural resistance depends on the ability to resist a comprehensive set of load combinations comprising the gravity loads and the thermally induced fire loads without undergoing failure. ...

Biotransformation of Perfluorooctane Sulfonamide (FOSA), 8:2 Fluorotelomer Alcohol (8:2 FTOH), and 6:2 Fluorotelomer Sulfonate (6:2 FTS) in Aqueous Film-Forming Foam (AFFF)-Impacted Soils under Oxic and Anoxic Conditions 

Yan, Pengfei (2022-12-05)  ETD File Embargoed
The use of aqueous film-forming foams (AFFFs) for fire suppression over decades has resulted in contamination of numerous sites by per- and polyfluoroalkyl substances (PFAS). However, the environmental fate and transformation ...

Comparison of Vegetation Types for Prevention of Erosion and Shallow Slope Failure Along Roadways 

Asima, Homayra (2022-08-03)
Shallow slope failures due to erosion are common occurrences along roadways in Alabama due to the prevalence of high intensity rainfall in the region. The use of vegetative covers is a reasonable solution to stabilize newly ...

Component Level Testing of a Large Area Maintenance Shelter 

Koontz, Lloyd (2023-08-04)  ETD File Embargoed
Large Area Maintenance Shelters (LAMS) are used by the United States military as temporary shelters for equipment and maintenance. After several LAMS structurally failed in wind speeds within the design parameters, the Air ...

A ‘Concentrate-&-Degrade’ Technique for Cost Effective Adsorption and Degradation of Per-and Polyfluoroalkyl Substances in Water 

ZHU, YANGMO (2022-07-25)
The overarching goal of this research is to develop and test a new class of carbon-photocatalyst composites for enhanced adsorption and destruction of per- and polyfluoroalkyl substances (PFAS) in water and field water. ...

A ‘Concentrate-&-Degrade’ Technology for Cost-Effective Adsorption and Photodegradation of Per-and Polyfluoroalkyl Substances in Municipal Landfill Leachate 

Zulfeqar, Najibullah (2022-11-29)
Per-and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been widely used in industry and daily consumer products. Due to the wide application of these products and their recalcitrant nature ...

A Conceptual Model of Design-Build 

Fuller, Ashley (2023-04-03)  ETD File Embargoed
Design-build is a project delivery method with roots in the ancient concept of the “master builder” where responsibility for both design and construction reside in one person. Despite the dominance of design-bid-build in ...

Construction and Calibration of Large-Scale Rainfall Simulators 

Etheridge, Jacob (2023-04-24)
Large-scale rainfall simulation offers valuable insight into the effectiveness of erosion control practice. While small and intermediate-scale apparatuses can analyze the effects of splash and sheet erosion on a slope, ...

A Critical Opportunity: Lead in Drinking Water at Child Care Facilities 

Stanbrough, Elizabeth (2021-01-19)
There is no safe level of lead exposure. As exposure from point sources like lead paint have been reduced through legislation, non-point sources such as drinking water have become a greater proportional source of total ...

Design and Performance of Open-Graded Friction Course Mixtures Containing Epoxy Asphalt 

Anand, Anurag (2021-11-30)
Open-Graded Friction Course (OGFC) is a type of pavement primarily composed of coarse aggregates and high asphalt content. Higher permeability, better friction resistance, improved visibility, reduced pavement noise, and ...
