THE CONTRACTOR SHALL DEVELOP A FUZZY SET METHODOLOGY FOR UNCERTAINTY ANALYSIS IN PROBABILISTIC SEISMIC SAFETY ASSESSMENT OF NUCLEAR POWER PLANTS. FUZZY SET LOGIC WILL BEUSED FOR COLLECTING, QUANTIFYING AND PROPAGATING SUBJECTIVE,ENGINEERING JUDGEMENT USED IN THE UNCERTAINTY ANALYSIS. IN PHASE I, FEASIBILITY OF THE PROPOSED APPROACH WILL BE DEMONSTRATED BY APPLYING IT TO SELECTED PARTS OF A PROBABI ...

The goal of this project is to develop a portable system for the real-time detection and quantification of adenovirus in wastewater. The system is based on a small, portable flow cytometer that was developed and is being marketed by Becton Dickinson Biosciences (BDB) under the trade name FACSCount¿ for use in selected medical and research applications. Unlike previous efforts to apply flow cytome ...

A novel, environmentally benign antimicrobial surface modification based on immobilized quaternary ammonium-functionalized dendrimers is proposed for the prevention of biofilm formation. Dendrimers are unique nanomaterials that have attracted attention as possible antimicrobial agents due to their compact structure, high local charge density of functional surface groups, unique carrier properties, ...

Dynaflow, Inc., proposes the development of a novel jet-induced cavitation process for the removal of various pollutants¿including pesticides from wastewater discharge¿ that would be economical, readily applicable to both large- and small-scale systems, and that does not produce potentially hazardous by-products of chlorination and ozonation. Ultrasonically induced cavitation is known to be capa ...

THIS PROPOSAL IS CONCERNED WITH THE ECONOMIC REMOVAL OF HYDROGEN SULFIDE, A TOXIC MATERIAL, FROM SOUR NATURAL GAS AND PETROLEUM PRODUCTS. THE CURRENT STATUS OF H2S PROCESSING IS REVIEWED. THE CHEMISTRY OF SULFUR AND SULFIDE IN AQUEOUS SOLUTIONS AND PRELIMINARY WORK ALREADY CARRIED OUT IN THE CONTINUOUS ELECTROLYSIS OF H2S TO YIELD HYDROGEN AND SULFUR ARE BRIEFLYDISCUSSED. THE ESTIMATED ECONOMIC GA ...

New environmental regulations have identified many of the currently used oxidizing agents employed for industrial waste control, disinfection, and wastewater treatment as a caveat that must be addressed. Ferrate has potential for becoming the alternative of choice because of its aggressive oxidation properties and its negligible impact on the environment. However, there has been little industrial ...
