The effect of an external magnetic field on a critical point for phase transitions in a dusty plasma is investigated. It is shown that the ambient magnetic field increases the effective hard core radius of dust particles, which, in turn, would affect a critical point in terms of the Coulomb coupling parameter and the ratio between the inter-dust grain spacing and the dusty plasma Debye radius. ...
A review is presented of recent experiments performed on the University of Iowa DC discharge dusty plasma device on various aspects of dust acoustic waves. A brief introduction to the physics of dusty plasmas and the dust acoustic wave is first presented. Three experiments are then described: (i) observation and interpretation of large amplitude (nonlinear) dust acoustic waves; (ii) evolution o...
dust pollution has become a serious environmental problem especially in recent decades. the present study aim was the investigation of the levels of pm10 concentration in kermanshah, western iran and also measured five important heavy metals (pb, cd, as, hg and cr) in some samples during 2005 to 2011.a total 2277 samples were collected from air pollution measurement station belonging to the dep...
If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generations of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis (or the atomic fact, or whatever you wish to call it) that all things are made of atoms—little particles that move around in perpetual motion, at...
