Role of relative humidity in the survival of airborne Mycoplasma pneumoniae.
Aerosols of Mycoplasma pneumoniae were studied at several relative humidities at a controlled temperature of 27 C. Production of an experimentally reproducible aerosol required preatomization of the organism in its suspending fluid and was dependent on the type of fluid used in atomization as well as on the procedures used to produce an aerosol. The airborne particles studied were within the ra...
متن کاملColonization of tomatoes by Salmonella montevideo is affected by relative humidity and storage temperature.
The influences of the relative humidity (RH) and storage temperature on the colonization of tomato surfaces by Salmonella Montevideo were studied. Red, ripe tomatoes (Lycopersicon esculentum) were spot inoculated in three separate trials with 100 pl (approximately 10(6) CFU) of Salmonella Montevideo and stored for 90 min at 22 degrees C under 97% RH to facilitate attachment of cells to the blos...
متن کاملEffect of temperature on survival of airborne Mycoplasma pneumoniae.
Aerosols of Mycoplasma pneumoniae were prepared at each of eight relative humidities between 0 and 85% and at five separate temperatures between 10 and 43 C. Survival of these organisms was found to be a function of both relative humidity and temperature. However, the temperature response was mediated by humidity in that the effects of temperature could be observed only if some water vapor was ...

متن کاملEstimation of Evolution of Relative Humidity Distribution for Concrete Slabs
Realistic prediction of concrete shrinkage and creep requires the calculation of the distributions of relative humidity at various times. Although the distributions of the relative humidity can be computed by numerical methods from the differential equation for diffusion, simple prediction formulas can facilitate structural analysis. The purpose of this paper is to present a simple formula for ...
