We present a low-pressure, automated, semi-continuous Gas-Particle Ion Chromatograph to measure soluble ionogenic gases and soluble ionic constituents of PM2.5. The system utilizes a short separation column, an isocratic carbonate eluent and post sup

Closure experiments were completed to compare measured and modeled aerosol optical properties and their dependence on controlled relative humidity (RH) and wavelength of light. NaCl, (NH4)2SO4, and NH4NO3 aerosol particles with approximate geometric

Atmospheric aerosol particles consisting of ammonium sulfate [(NH4)2SO4] or sodium chloride (NaCl) have reasonably well-defined hygroscopic properties compared to other materials in aerosol particles, such as organic material. The effect of internall

An experimental system to collect cloud condensation nuclei (CCN) onto filters in amounts sufficient for chemical analysis is described. This experimental apparatus is designed to process ambient air at a rate of more than 1 m3/min. Two identical sys

An effective information system is an essential prerequisite to delivering quality patient care at competitive costs. From scheduling and billing to complex treatment machine control and verification, the quality of the information system strongly af

Models of dust emissions by wind erosion (including winds associated with regional activity as well as dust devils) and vehicular disturbances of unpaved roads were developed, calibrated,and used to estimate alkaline dust emissions from elemental soi

This third progress report describes the status of our efforts to develop the instrumentation to collect cloud condensation nuclei (CCN) in amounts sufficient for chemical analysis. During the fall of 1992 we started collecting filter samples of CCN

Fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith), oviposition on paper towels treated with water extracts of corn leaves, FAW larvae, larval frass, and artificial diet was reduced significantly compared with towels treated only with the solve

The interaction of two growing droplets in a supersaturated atmosphere has been examined, and the temperature and vapor density profiles have been determined. It is found that the smaller droplet tends to “catch up” with the larger at a slower ra
