Effect of speed adaptation on performance in a self-paced tracking task.

12 Ss were required to perform a self-paced tracking task designed to simulate 'hazardous' road conditions. Those 6 Ss who had previously been exposed to a simple, high-speed version of the task travelled faster and made more errors on the hazardous task than 6 control Ss who performed the hazardous task throughout the experiment. The findings supplement earlier studies of the effect of speed adaptation on the judgment of speed and suggest that, in addition to perceptual distortions, an acquired motivation for speed may be an important factor in the behaviour of drivers leaving high-speed roads.

Survival of airborne Pasteurella tularensis at different atmospheric temperatures.

The aerosol survival, recovery, and death rate of Pasteurella tularensis SCHU S5 disseminated in particle sizes of 1 to 5 mum were significantly affected by air temperature. The highest aerosol recovery of viable P. tularensis was observed within -7 and 3 C; the recovery decreased significantly below and above this temperature range. The death rate of airborne P. tularensis was not significantly influenced by an increase in temperature from -40 to 24 C. However, a progressive increase in atmospheric temperature from 24 to 35 C resulted in increased death rates; thus, a linear relationship appeared to be present between the temperature and death rates. At 49 C, the recoveries of viable airborne P. tularensis were significantly lower and the death rates were higher than at the other temperatures.

Effect of NO 2 on airborne Venezuelan equine encephalomyelitis virus.

Studies were conducted to determine the effect of nitrogen dioxide (NO(2)) on aerosol survival and biological decay rate of Venezulean equine encephalomyelitis (VEE) virus and spores of Bacillus subtilis var. niger. The NO(2) concentrations used in the experiments were 0.5, 5, and 10 ppm at 24 C and 85% RH. The survival of airborne VEE virus disseminated as particles 1 to 5 mum in diameter was significantly influenced by the presence of 5 ppm of NO(2). At this concentration, the biological decay rate increased threefold and the aerosol recovery and aerosol survival of the VEE virus were significantly lower than at 0.5 ppm or in the absence of NO(2). Airborne spores of B. subtilis were not significantly affected by as much as 10 ppm of NO(2).
