THE REDUCED ENTRAINMENT PRECIPATATOR WILL HAVE IMPROVED COL-LECTION EFFICIENCY FOR DUSTS HAVING EITHER HIGH OR LOW ELEC-TRICAL RESISTIVITIES. THIS OBJECTIVE IS ACCOMPLISHED BY PRO-VIDING A POROUS, FABRIC COLLECTING SURFACE. A SMALL PORTION (TYPICALLY LESS THAN 20%) OF THE DIRTY GAS STREAM IS DRAWN THROUGH THE COLLECTED DUST CAKE AND THE POROUS COLLECTING PLATE BY A SEPARATE FAN. THIS SMALL FLOW TH ...

TWO APPROACHES WILL BE EXAMINED TO SIGNIFICANTLY IMPROVE THESENSITIVITY OF LAUNDRY MONITORS TO DETECT AND SPECIFY LOCATION OF HOT PARTICLES ON LAUNDERED GARMENTS. THESE PROPOSED TECNIQUES HAVE HIGH POTENTIAL FOR DETECTING BOTH LOW ENERGY BETA AND ALPHA PARTICLE RADIATION AS WELL AS IMPROVING SENSITIVITY BY REDUCING BACKGROUND COUNT RATE.

The use of enzyme-linked immunosorbent assay (ELISA) to detect contaminants such as solvents, fuels, and pesticides in soil and water samples is now well established. Although ELISA and related methods can facilitate analysis of samples, several washing and separation steps are involved that require 30 to 120 minutes per sample to reach equilibrium. Recently, near infrared fluorescence immunoassa ...

A number of industrial processes generate wastewater with mercury contamination. Existing cleanup processes have difficulties in achieving low mercury discharge limits, especially in the presence of competing metal ions already below their discharge limits. Commercial ion exchange media are not selective for mercury, so other metal ions compete with mercury for binding sites. Consequently, excess ...

BACTERIA INDUCE MANY OF THE PROBLEMS ASSOCIATED WITH PUBLIC PROBLEMS ASSOCIATED WITH WATER BORNE PATHOGENS. IN ADDITIONTASTE, ODOR, COLOR AND TURBIDITY PROBLEMS ARE SOMETIMES CAUSED BY BACTERIAL, FOULING AND CORROSION ARE ALSO CAUSED BY BACTERIA. FOULED WATER SYSTEM COMPONENTS PROMOTE DEVELOPMENT OF PROTECTED OR SHIELDED CONSORTIA OF BACTERIA WHICH DECREASES THE EFFGECTIVENESS OF CHLORINE (OR OTHE ...
