A Comparative Study Of Carbon Nanotubes And Granular Activated Carbon: Physicochemical Properties And Adsorption Capacities
(Civil & Environmental Engineering, 2014-09-17)
Adsorption technologies with activated carbon have proven their prominence in wide variety of industrial applications for the removal of pollutants from gaseous streams for generations. Nanoadsorbents due to their unique ...
Selective Catalytic Reduction Of Nitric Oxide Over Cerium-doped Activated Carbons
(Civil & Environmental Engineering, 2014-03-10)
Selective catalytic reduction (SCR) with ammonia for diesel engine NOx reduction using activated carbon (AC) was studied. Comparisons of unmodified and cerium-doped Granular Activated Carbon (GAC), Activated Carbon Fiber ...
Response Of Unsaturated Silty Sand Over A Wider Range Of Suction States Using A Novel Double-walled Triaxial Testing System
(Civil & Environmental Engineering, 2014-09-17)
In recent decades, the state-of-the-art of our understanding of unsaturated soil performance has been considerably enhanced by incorporating novel and advanced features to the conventional testing devices such as direct ...
Numerical Modeling Of Ground Movements Associated With Trenchless Box Jacking Technique
(Civil & Environmental Engineering, 2014-09-17)
The Trenchless Technology (TT) is defined as a family of methods used to install, renew, replace or renovate new pipe/box or existing pipe/box underground with little or no surface disruption. TT is divided into two main ...
Evaluation Of Surface Transportation Funding Alternatives Using Criteria System Established Through A Delphi Survey Of Texas Transportation Experts
(Civil & Environmental Engineering, 2014-03-12)
For more than a decade, transportation officials have been concerned that, at current levels, the fuel tax, the primary funding source of surface transportation in the United States, would not provide enough revenue to ...
Non-linear Finite Element-based Material Constitutive Law For Zero Slump Steel Fiber Reinforced Concrete Pipe Structures
(Civil & Environmental Engineering, 2014-03-12)
This study presents a comprehensive investigation of performance and behavior of steel-fiber reinforced concrete pipes (SFRCP). The main goal of this study is to develop the material constitutive model for steel fiber ...
Sustainable Slope Stabilization Using Recycled Plastic Pin In Texas
(Civil & Environmental Engineering, 2014-03-12)
Shallow slope failures are predominant in the North Texas area and pose significant maintenance problems for the Texas Department of Transportation (TxDOT). As a cost effective alternative, the Recycled Plastic Pin (RPP) ...
Spatial Variability Models And Prediction Analysis Of Soil Properties Using Geostatistics
(Civil & Environmental Engineering, 2014-12)
Soils are composed of solid, water and air phases whose characteristics are highly variable. The interactions of these phases in the soil matrix can lead to different types of topographical formations and characteristics. ...
Evaluation Of Lightweight Geofoam For Mitigating Bridge Approach Slab Settlements
(Civil & Environmental Engineering, 2014-12)
The bump at the end of a bridge infrastructure is one of the frequent problems found in Texas and other states. Transportation agencies spend millions of dollars annually to repair the bump problem. The major cause of the ...
Development Of Linear Regression Model For Predicting Water Quality Parameters From Anaerobic Treatment Of Vinasse
(Civil & Environmental Engineering, 2014-12)
One of the most prominent biofuels today is ethanol. The production of ethanol from biomass, whether from sugar crops, starch crops, dairy products, or cellulosic materials, results in the production of a high-strength ...
