Coarse Particles and Dust Storm Mortality In a paper titled "Episodes of High Coarse Partide Concentrations Are Not Associated with Increased Mortality," Schwartz et al. (1) concluded that "coarse particles from windblown dust are not associated with mortality risk." The authors seem to have overlooked the medical literature on the health effects of the historic U.S. dust storms of the dust bow...

A surprising observation in dusty plasma experiments is that the dust thermal energy density, P_{d}∝n_{d}T_{d}, is typically much greater than n_{d}T_{n} (where n_{d} and T_{d} are the dust density and temperature, and T_{n} is the neutral temperature), even though the dust particles would be expected to be in thermal equilibrium with the neutrals. We show here, theoretically and experimentally...

The results of experimental studies of organic dust detonation in the presence of chemically inert particles are presented. Tests were carried out using a vertical detonation tube, and direct streak pictures showing the flame acceleration and pressure and temperature records were obtained. Flax dust, dispersed in an oxygen atmosphere, was used as the fuel, and two kinds of quartz sand were intr...

Micron size dust particles influence on nonlocal properties of complex gas discharge plasma are simulated. Plasma is described within limits of diffusion approximation, combined with OML approximation for dust component. The current-voltage characteristics as the easy-to-observe measure of dust influence on the total amount of charged particles, as well as the radial distributions of plasma com...

This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract Heterogeneous processes on dust particles are important for understanding the chemistry and radiative balance of the atmosphere. This paper investigates an intense Asian dust storm episode observed at Mount Heng (1250...

In this paper, the influence of dust particles on the plasma losses in a complex plasma afterglow is studied. It is shown that the dust particles can drastically shorten the plasma loss time by absorption-recombination onto their surfaces. The dust particle absorption frequency increases with the dust density but the dependence is not linear for high dust density. Finally, the possible use of d...

Dust particle growth instability and residual dust charges in a rf discharge have been studied. Dust particles were grown by sputtering of a polymer material previously deposited on the electrodes. We show that two regimes of the dust particle growth instability exist and are characterized by their frequencies. An empirical explanation based on the assumption of different dust particle growth r...
