Use of Hydroxyapatite Derived from Catfish Bones for Remediating Uranium Contaminated Groundwater
(2009-05-20)
Hydroxyapatite derived from catfish bones was used for removing uranium from contaminated groundwater. Literature review indicated that apatites from various sources of fish bones can be used for metal remediation. The ...
Experimental and Numerical Analysis of Groundwater-Surfacewater Interaction in Horizontal and Sloping Unconfined Aquifers.
(2009-07-15)
We investigated the interaction between the water moving from an unconfined aquifer and a surfacewater body. This interaction can occur during or after a rainfall event, which can cause the groundwater table to change. We ...
Erodibility Testing of Cohesive Soils
(2009-07-13)
The Erosion Function Apparatus (EFA) is used to measure erosion rates for cohesive soil samples subjected to water velocities tangent to the sample surface. EFA testing was performed on soil samples taken from three bridge ...
Mercury Immobilization by Subsurface Reactive Barriers
(2009-08-17)
Mercury contamination is becoming a prevalent problem for environmental engineers. Chlor-alkali plants and coal fire power plants are the main contributors to the spread of this neurotoxin into the environment. Mercury ...
Combined Flexural and Cable-like Behavior of Ductile Steel Beams
(2009-08-28)
In addressing the propensity of steel building structures to experience progressive collapse due to extreme loading conditions (e.g., blast), current design guidelines propose the use of a threat-independent approach that ...
Biodecolorization of Paper Mills Wastewater Using Anaerobic Composting
(2009-08-04)
This research studied the feasibility of using anaerobic composting for decolorizing effluents in the pulp and paper industry. While color is regarded as an aesthetic problem, there are several adverse effects associated ...
Evaluation of Semi-Adiabatic Calorimetry to Quantify Concrete Setting
(2009-12-14)
Although setting is routinely measured in practice, current methods for determining concrete setting have been criticized for being impractical, arbitrary, and lacking correlation to field data. In recent years attempts ...
