Understanding the Flow and Mixing Dynamics of Saline Water Discharged into Coastal Freshwater Aquifers
(2008-09-09)
Typically the origin of saltwater intrusion into coastal aquifers has been attributed to the reduction of freshwater flux (or head) in the aquifer. This intrusion is the most common natural source of saltwater contamination ...
Determination of Elastic Constants and Damage in Ceramic Matrix Composites Using Ultrasonic Wave Speed Measurements
(2008-09-09)
MATLAB programs were developed to compute the elastic constants and damage of ceramic matrix composites using ultrasonic wave speed measurements. The matrix of elastic stiffnesses, C, relates the material stresses and ...
Predicting Field Performance on the NCAT Pavement Test Track
(2008-09-09)
An experimental facility has been constructed near the campus of Auburn University for the purpose of conducting research to extend the life of flexible pavements. Experimental sections on the 2.8 kilometer Pavement Test ...
Evaluation of New Technologies for Use in Warm Mix Asphalt
(2008-09-09)
Several new processes have been developed with the goal of reducing the mixing and compaction temperatures of hot mix asphalt without sacrificing the quality of the resulting pavement. Three potential Warm Mix Asphalt ...
Removal of Copper(II) and Lead(II) from Soils by Poly(Amidoamine) Dendrimers and Reductive Immobilization of Chromium(VI) by Stabilized Zero-Valent Iron Nanoparticles
(2008-09-09)
This research investigated the feasibility of using poly(amidoamine) PAMAM dendrimers for removal of copper(II) and lead(II) from soils, and using a new class of stabilized zero-valent iron (ZVI) nanoparticles for reductive ...
Decreasing Lead Bioaccessibility In Soils With Phosphate Amendments
(2008-09-09)
Ingestion of Pb-contaminated soil has been proposed as a primary exposure pathway for elevated blood Pb levels in young children (Dudka and Miller, 1999). Children are often exposed to soils contaminated with toxic metals ...
Durability of Nitinol for Structural Applications
(2008-09-09)
Nitinol is a shape memory alloy that has recently been studied for its suitability as a material in energy dissipation devices in structures. The alloy has excellent structural capabilities in terms of strength and ...
Comparison of the Theory, Application, and Results of One- and Two-Dimensional Flow Models
(2008-09-09)
The accurate simulation of flooding is crucial in the design of safe, cost-effective hydraulic structures. Hydraulic engineers are faced with several difficult decisions that will determine the accuracy of any modeling ...
Hypothetical Analysis on Cost Effectiveness of Centerline Rumble Strips as a Crash Countermeasure
(2008-09-09)
Rural roads are mostly undivided highways with high speed, two-way traffic.
These factors coupled with inattentive driver behavior increase the risk of frontal and
sideswipe collisions. Widening of roads and installation ...
Documentation of the Rapid Replacement of Four GDOT Bridge Decks
(2008-09-09)
The Alabama Department of Transportation (ALDOT) has many interstate bridges near downtown Birmingham which have good substructures and superstructures, but suffer from significant deck cracking and deterioration. The ...
