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 project objectives are to develop and evaluate a generic methodology foremission control of a wide variety of air toxic particulate using a revolutionarybreakthrough in filtration technology based on the recently developed BoundaryLayer Momentum Transfer (BLTM) concept. This novel filter is designed to augmentand substantially improve separate conventional toxic treatment/ reclamationmethodol ...

Industrial wastewater containing toxic waste compound and metal ions pose manyproblems of disposal. The most generally used method of removing metalcontaminants is lime treatment to precipitate metals as hydroxides. The metalis not normally recovered resulting in the need for sludge disposal. The costof sludge disposal plus fewer available disposal sites makes that methodincreasing less attract ...

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 ...

No one questions the philosophy that it is better to avoid industrial pollutionrather than to attempt the clean up of an environmentally abused site.Unfortunately, we are slow to learn this lesson and hazardous wastes become moreexotic and continue to increase. Causing 21 of the 28 EPA superfund sites in theSilicon Valley (Witkowski and Menon 1991), the semiconductor industry was, andcontinues to ...

RECENT ASSESSMENTS ESTIMATE U.S. CROP LOSSES FROM ELEVATED OZONE LEVEL AND OTHER OXIDANTS (SULFUR DIOXIDE, NITROGEN DIOXIDE) TO BE AS MUCH AS $5 BILLION ANNUALLY. ADDITIONALLY,SEVERE FOREST DAMAGE MAY RESULT FROMPOLLUTION-RELATED OXI- DANTS PARTICULARLY IN EUROPE WHERE THERE HAS BEEN A DRAMATICDECLINE IN FOREST ECOSYSTEMS OVER THE PAST SIX YEARS. THIS RESEARCH IS DIRECTED AT THE MITIGATION OF SUCH ...

IONICS RESEARCH INC. (IRI) HAS DETERMINED THAT UNCOATED CAPILLARY COLUMNS CAN BE USED TO CONCENTRATE ORGANICS FROM WATER. THE METHOD IS EXCEEDINGLY SIMPLE AND RAPID (10 MINUTES PER 100 ML), YET EFFECTIVE. IRI PLANS TO INVESTIGATE THE POTENTIAL OF THIS TECHNIQUE FOR THE DEVELOPMENT OF AN INSTRUMENT SUITABLE FOR THA NALYSIS OF ORGANICS AT THE PART-PER-TRILLION LEVEL IN WATER AND WASTEWATER. SUCH AN ...
