A FREE FALL WATER SAMPLER BASED ON THE CHOPSTICK WATER SAMPLER BAG WILL BE DEVELOPED. THIS PORCUPINE SAMPLER WILL BE CAPABLE OF TAKING UP TO 36 THREE LITER WATER SAMPLES AT DEPTHS CONTROLLED FROM THE SURFACE, OR AT DEPTHS DETERMINED BY AN INTERNAL CONTROLLER. THE SAMPLE WILL BE OPTIMIZED FORMINIMUM TRAVEL TIME FROM THE SURFACE TO THE BOTTOM AND BACK SO THAT THE CURRENT FOUR HOUR ON STATION TIME FO ...

ACTIVATED CARBON IS FREQUENTLY USED TO ABSORB ORGANIC MATERIALS FROM AIR AND WATER IN MANY INDUSTRIAL OPERATIONS. IN PARTICULAR, ACTIVATED CARBON IS USED TO ABSORB VOLATILE ORGANICS FROM THE EXHAUST AIR IN THE PRINTING AND PAINTING INDUSTRIES. A NECESSARY PART OF SUCH OPERATIONS IS THE REGENERATION OF THE ACTIVATED CARBON WITH SIMULTANEOUS RECOVERY OF THE ORGANIC MATERIAL, WHICH IS GENERALLY VERY ...

IN MANY FLUID INJECTION PROCESSES USED FOR OIL RECOVERY, SUCH AS WATERFLOODING, THE INJECTED FLUIDS FLOW PREFERENTIALLY THROUGH THE ROCK ZONES OF HIGH FLOW CAPACITY (HIGH PERMEABILITY), BYPASSING OIL THAT IS PRESENT IN THE TIGHTER PARTS OF THE RESERVOIR ROCK. THIS MAY RESULT IN HIGH WATER-TO-OIL-PRODUCING RATIOS AND ABANDONMENT OF A PROJECT AT A RELATIVELY LOW VOLUMETRIC SWEEP EFFICIENCY. ONE APPR ...

THIS PROJECT IS TO DESIGN AND CONSTRUCT A MICROCOMPUTER-BASED INSTRUMENT FOR QUANTITATING SIZE DISTRIBUTIONS OF NUCLEIC ACIDS (DNA AND RNA) SEPARATED ACCORDING TO SIZE BY GEL ELECTROPHORESIS. THE STARTING POINT FOR ANALYSIS OF FLUORESCENCE-STAINED DNA IN GELS WILL BE THE IMAGE DIGITIZATION OF THE ENTIRE GEL ELECTROPHORETIC PATTERN (OR SPECIFIED PORTIONS OF IT) SO THAT THE RELATIVE INTENSITIES OF F ...
