Form perception with the tongue was studied with a 49-point electrotactile array. Five sighted adult human subjects (3M/2F) each received 4 blocks of 12 tactile patterns, approximations of circles, squares, and vertex-up equilateral triangles, sized to 4x4, 5x5, 6x6, and 7x7 electrode arrays. Perception with electrical stimulation of the tongue is better(More)
The starvation-survival of Escherichia coli in seawater was assessed by plate and epifluorescence counts, 3H-label decrease, cellular DNA concentrations, and metabolic activities. These assays were performed on two types of populations, adapted and non-adapted to seawater. The number of viable cells in the adapted population remained constant throughout(More)
The mortality ofEscherichia coli in seawater was assessed by viable counts, electron transport system activity, and cellular3H-labelling. Filtration was used to assess the grazing mortality. Cellular radiolabelling and electron transport system activity were useful methods for assessingE. coli survival in seawater. The decrease in the3H-label as a method to(More)
As an approach for assessing the dynamics of bacterial population in seawater, the survival of five isolated marine bacteria strains was assessed by the disappearance of radioactivity in the cold trichloroacetic acid (TCA)-insoluble fraction from a previously3H-labeled culture. Metabolic activity during survival experiments was assessed by the measurement(More)
Four self-conjugative plasmids conferring mercury resistance were exogenously isolated from coastal Mediterranean sea water. All the plasmids isolated (93.2, 73.1, 65.2 and 221 kb) showed narrow-spectrum mercury resistance, and no UV resistance; three of them conferred cadmium resistance (Cdr 1.5 mM) and two of them encoded streptomycin resistance (50(More)
