The Influence of Organic Metabolites Binding with Ferric Iron on Corrosion Mechanisms in Oil and Gas Production Water
(2018-05-11)
Corrosion of carbon steel is a potential hazard to oil and gas production infrastructure. The total annual cost of corrosion in the oil and gas production industry is estimated to be $1.372 billion in the USA (Simons, ...
Investigation of flexural behavior of reinforced concrete with 3D printed glass fiber reinforced polymer
(2022)
More than 40 years of Fiber Reinforced Polymers in Civil Engineering has shown the widespread use and advantages of these unique composites. FRP composites are high strength, lightweight, corrosion resistant materials that ...
Effect of Curing Temperature on Nanomodified Fiber-Reinforced Polymer Composites
(2023-12-15)
Dispersion of pristine and functionalized-COOH carbon nanotubes (CNTs) into the resin matrix used to develop fiber-reinforced polymer (FRP) composites is known to improve FRP properties such as shear strength, UV resistance, ...
Temporal and Spatial Variations in Sediment Trace Metal Concentrations in Streams, Rivers, and a Reservoir near a Derelict Lead-Zinc Mining District
(2021-05)
Historic lead and zinc mining in the Tri-State Mining District has ceased, but the legacy of
trace metal contamination (Cd, Cu, Ni, Pb, and Zn) throughout the region still exists. This thesis
focuses on stream sediments ...
Developing a Water Balance Model to Estimate Consumptive Use in the Southeast Watershed Planning Region of Oklahoma
(2020-05-08)
With the passage of the Water for 2060 Act, Oklahoma established a statewide goal of consuming no more freshwater in 2060 than was consumed in 2012. However, there currently does not exist a quantifiable method to estimate ...
The Role of Solar-Powered Float-Mix Aerators on Iron Retention in Passive Treatment Oxidation Ponds
(2019-12)
In passive treatment of net-alkaline mine drainage, oxidation ponds are typically the primary process unit designed to promote iron oxidation, hydrolysis, and precipitation. Iron oxidation kinetics can be accelerated by ...
Oklahoma Earthquakes and Their Effects on Highway Bridges
(2017-05-13)
Oklahoma is presently experiencing a higher rate of earthquake activity than historically
observed. Historical data on earthquake-induced damage to Oklahoma bridges is limited,
so the Oklahoma Department of Transportation ...
Laboratory Characterization of Foamed WMA Containing RAP
(2019-08-01)
For more than two decades, the asphalt paving industry has been using Reclaimed Asphalt Pavement (RAP) and various types of Warm Mix Asphalt (WMA) technologies in the production of asphalt mixes to reduce impact on the ...
The Performance of Cement-Limiting and High-Volume Recycled Material Mix Designs for Use in Concrete Pavements Through Laboratory and Field Implementation Testing
(2016-05)
Conventional methods of replacing roadways are beginning to negatively impact the environment. The continued use of high volumes of cement will continue to exacerbate the increasing levels of carbon dioxide. In addition ...
