Experimental Study of the Settlement of Shallow Foundations
This article describes the main results obtained experimentally by the French Bridge and Road Research Laboratories on the settlement of shallow foundations under centered vertical loads....
Settlement Analysis for 450 Meter Tall KLCC Towers
The site evaluation and settlement analysis performed for the two tallest buildings in the world currently under construction, are described. The site evaluation resulted in shifting building...
Load Settlement curve Method for Spread Footings of Sand
A newly developed method is presented to predict the complete load settlement curve for square spread footings on sand loaded at their center with a vertical load and with an embedment...
Test and Prediction Results for Five Spread Footings on Sand
A separate volume summarizes this prediction symposium. It is available from ASCE in New York and is entitled as listed above. This prediction event took place during the conference and...
Subjective De-Biasing of Data Sets: A Bayesian Approach
In this paper, we examine the relevance of data sets (for instance, of past incidents) for risk management decisions when there are reasons to believe that all types of incidents have...
Treatment of Oil in Water Emulsions by Ceramic-Supported Polymeric Membranes
A novel membrane was developed by growing polymer chains from the surface of a porous ceramic support, resulting in a composite membrane which combines the mechanical properties of the...
Evaluating Activated Sludge Secondary Clarifier Performance: A Protocol
To establish a consistent methodology for evaluating secondary clarifier performance, the ASCE Clarifier Research Technical Committee prepared procedural guidelines in the form of a draft...
Evaluation of Fe oxide-coated GAC for removal and recovery of Cu(II) from water
A composite solid, prepared by precipitating an Fe oxide onto granular activated carbon (GAC), was evaluated as an adsorbent for the removal and recovery of Cu(II) from water. Relative...
Chelating Composite Membrane: Its Application in Selective Heavy-Metal Solid-Phase Separation
Selective removal of small amounts of heavy metals from the background of large amounts of innocuous sludge or slurry is a challenging separation problem. Conventional fixed-bed sorption...
Modeling of Chemical Inhibition of Nitrification
This work contains two quantitative structure-activity relationships (QSARs) modeling chemical inhibition of nitrification, one for heterocyclic compounds and one for acetylenic materials....
Assessing the Reliability of Low Pressure Membrane Systems for Microbial Removal
Low pressure membrane systems are used for microorganisms control in water treatment processes. In this article, the efficiency and reliability of this process is evaluated. Microorganism...
Colloidal Fouling of Reverse Osmosis Membranes
Experiments on the fouling of thin film composite and cellulose acetate reverse osmosis membranes by aluminum oxide colloids are reported. Fouling was significant at high ionic strengths,...
DBP and Hardness Control by Membrane Filtration
Ultra (UF) and nanofiltration (NF) were evaluated for removal of disinfection by-product (DBP) precursors and hardness from Rio Grande water in New Mexico and Texas. In order to compare...
Treatment of Drinking Water Containing Bromate and Bromide Ions
Granular activated carbon and reverse osmosis nanofiltration and hyperfiltration were examined for both bromate and bromide ion removal using surface treated water in New Jersey. Bromate...
Effects of Molecular Oxygen and pH on the Adsorption of Aniline to Activated Carbon
This paper examines the influence of molecular oxygen and pH on the adsorption of aniline to F-300 Calgon Carbon. Molecular oxygen increased the adsorptive capacity of GAC for anilines...
The Evaluation of Empty Bed Contact Time on the Biodegradation of Pentachlorophenol using an Anaerobic GAC Fluidized Bed
The objective of this research is to evaluate the effects of decreasing the empty-bed contact time (EBCT) on pentachlorophenol and its intermediates utilizing an anaerobic granular activated...
NCASI Experiment Related to Validation of Equilibrium Partitioning (EP) Theory
A review of NCASI's technical studies related to evaluating equilibrium partitioning (EP) theory as it is commonly applied in regulatory setting is presented. Although interim results...
Activated Carbon as a Catalyst for Polymerization of Phenolic Compounds
Previous studies by the principal investigator showed that the increase in the adsorptive capacity of activated carbon for phenolic compounds can be attributed to polymerization (oxidative...
Computation of a flood event using a two dimensional finite element model and its comparison to field data
This paper reports on an attempt to begin a rigorous field testing programme for two dimensional finite element flow models, examining the impacts of mesh resolution and numerical method...
Laboratory and Field Evaluation of Acoustic Velocity Meters
A project is currently underway to evaluate the performance of 27 acoustic flowmeters used at Hoover, Davis, and Parker Dams on the lower Colorado River. Field surveys and laboratory testing...
