Engineered Treatment of As-Laden Regeneration Brine from Ion Exchange Processes
(2006-05-15)
Arsenic (As) contamination of drinking water sources has been one of the most challenging global environmental issues. In the United States, the newly revised maximum contaminant level (MCL) of 10 µg/L requires thousands ...
Evaluation of the Maturity Method to Estimate Concrete Strength in Field Applications
(2006-05-15)
Estimating the strength of concrete is essential to contractors and engineers to allow concrete construction operations to proceed safely and expediently. The maturity method is a technique that allows the in-place concrete ...
Hypothetical Analysis on Cost Effectiveness of Centerline Rumble Strips as a Crash Countermeasure
(2006-05-15)
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
(2006-05-15)
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 ...
Determining the Optimum Compaction Level for Designing Stone Matrix Asphalt Mixtures
(2006-05-15)
As Stone matrix asphalt (SMA) becomes more widely used in the United States, there is a need to further refine its mix design procedure. Some states have found that 100 gyrations with the Superpave Gyratory Compactor (SGC) ...
Verification of the Superpave Gyratory Ndesign Compaction Levels
(2006-05-15)
The original Superpave Ndesign table contained 28 levels based on a limited laboratory experiment. This was later consolidated to 4 levels based on the sensitivity of mixture volumetric properties to Ndesign; however, ...
Tris(1,3-Dihydroxy-2-propyl)amine, A Planar Trialkylamine: Synthesis, Structure, and Properties. A Potential Precursor to Hypervalent Nitrogen
(2006-05-15)
The hindered amine tris(1,3-dihydroxy-2-propyl)amine, 36, is a potential precursor to possible examples of nitrogen hypervalency. There are no simple, effective, and general methods to synthesize hindered tertiary amines. ...
Compaction of Switchgrass for Value Added Utilization
(2006-05-15)
There are increasing concerns about energy prices, availability and utilization in the world. This has led to many governmental and privately sponsored studies and research on the potential of renewable energy from biomass. ...
Variation in populational size and composition within two summer colonies of endangered gray bats (Myotis grisescens)
(2006-05-15)
For >30 years, the endangered gray bat (Myotis grisescens) has been a priority in conservation efforts in the southeastern United States. As part of these conservation efforts, the Alabama Department of Conservation and ...
Analysis of p62-UBA interacting proteins
(2006-05-15)
Sequestosome 1/p62 interacts with and traffics K63-polyubiquitinated proteins through its ubiquitin associating domain (UBA). Herein we demonstrate that the hyperaccumulation of K63-polyubiquitinated proteins occurs in the ...
The Chinese Consumers' Changing Value System, Consumption Values and Modern Consumption Behavior
(2005-08-15)
China is traditionally regarded as a collectivistic society, in which the linkage between individuals is close and strong; people treasure tradition, benevolence, and conformity. However, as a result of economic growth ...
Coefficient Space Properties and a Schur Algebra Generalization
(2005-12-15)
Let K be an infinite field and Gamma = GL_(n)(K). If we linearly extend the natural action of Gamma on the set E of n-dimensional column vectors over K to the group algebra KGamma, then E becomes a KGamma-module. We then ...
An Evaluation of Nursery Techniques and Feed Management During Culture of Marine Shrimp Litopenaeus vannamei
(2005-12-15)
The use of indoor shrimp nurseries is often encouraged, especially prior to intensive and super-intensive shrimp culture. Potential benefits in subsequent grow out include; better control of stock inventory, better ...
The effects of herbivory on plant mating systems
(2005-12-15)
Inbreeding is common in many plant species. Inbreeding reduces heterozygosity and increases the expression of recessive deleterious alleles that cause inbreeding depression. The level or intensity of inbreeding depression ...
Process-Variation-Resistant Dynamic Power Optimization for VLSI Circuits
(2006-05-15)
Power dissipation is an increasingly critical issue in modern VLSI design and testing. Previously, linear programming (LP) based methods have been proposed for optimization of circuits for low power dissipation. However, ...
Numerical Modeling of Nasal Cavities and Air Flow Simulation
(2006-05-15)
Computational fluid dynamics (CFD) has many applications in biomedical engineering, such as simulating air dynamics in nasal cavities and lungs, blood flow in vessels, and blood flow in hearts. To perform CFD simulations, ...
A Technique for the Measurement of Relative Velocity between Parallel Plate Electrodes in Micromachined Structures
(2006-05-15)
Numerous applications exist for microstructures that contain two parallel oriented electrodes that experience relative motion. It is often desirable to measure the relative velocity between the two electrodes and then ...
Analysis of DC Power Systems Containing Induction Motor-Drive Loads
(2006-05-15)
The development of an analytical method used for conducting a power flow analysis on a DC power system containing multiple motor-drive loads is presented. The method is fast, simplistic, easy to implement, and produces ...
Packaging of Silicon Carbide High Temperature, High Power Devices - Processes and Materials
