Phosphorus chemistry under aerobic and anaerobic conditions in model two-celled waste stabilization ponds.
(1980)
This study involved a laboratory examination of the phosphorus interactions between the sediment and water as they occur on a diurnal basis in a waste stabilization pond under summer conditions in the southcentral U.S. At ...
Iron and sulfur microbial processes applied to the biodegradation of organic contaminants in groundwater.
(1998)
This research emphasizes microbial/mineral interactions associated with Fe$\sp{3+}$ and SO$\sb4\sp{2-}$ reduction. Simplified methods are developed to evaluate Fe$\sp{3+}, $ Fe$\sp{2+}, $ and S mineral species. These ...
Synthesis and Characterization of Porous Hydroxyapatite Ceramics for Batch and Column Treatment of Fluoride-Impacted Ground Water
(2019-05-10)
Nearly 200 million people worldwide are exposed to drinking water with elevated levels of naturally occurring fluoride. The World Health Organization recommends a maximum fluoride concentration of 1.5 mg/L in drinking water ...
Performance and environmental impact assessment of agricultural waste-based sorbents for phosphorus recovery and reuse
(2023-05)
Phosphorus is an essential resource, yet global phosphorous reserves are limited, and increasing quantity of high-grade ore is being mined and turned into fertilizers to meet the increasing demand of food. However, since ...
Municipal, irrigational and industrial future water requirements in Saudi Arabia.
(1982)
The future water requirements were matched against the available water resources, and it was found that the limited ground water reserves must play a major role in order to meet the future water requirements. To reduce ...
Seismic Vulnerability of Residential Structures in Nicaragua
(2009)
In recent times, many parts of the world have seen a trend of increased construction with reinforced concrete and masonry block systems. These systems can provide excellent seismic resistance when they are designed by an ...
The use of fecal bacteria in the assessment of the environmental impact by concentrated animal feeding operations on water quality.
(2004)
Many sources of pollution, including agricultural, industrial, and urban sources, can increase a stream or lake's nutrient and bacterial concentrations. In order to improve water quality, these sources must be identified, ...
A SUGGESTED DESIGN APPROACH FOR BUILT-UP COLD-FORMED COLUMNS BASED ON RESEARCH USING NONLINEAR FINITE ELEMENT METHOD
(2011)
A deficiency of the 2007 AISI specification, Sections C4 and D1.2 for built-up, coldformed
Advances using the ADCIRC hydrodynamic model: Parameter estimation and aspects of coupled hydrologic-hydrodynamic flood inundation modeling
(2011)
The ADCIRC hydrodynamic model has been used extensively for coastal modeling applications over the last twenty years. Within the last decade, modeling of hurricane storm surge has become one of its principal applications. ...
