The dynamics of two counter-streaming electron-positron-ion unmagnetized plasma shells with zero net charge is analyzed in the context of magnetic field generation in GRB internal shocks due to the Weibel instability. The effects of large thermal motion of plasma particles, arbitrary mixture of plasma species and space charge effects are taken into account. We show that, although thermal effect...

1. Science Summary A large variety of astrophysical objects are sites of powerful particle acceleration and impulsive energy release. The Sun provides us with an excellent nearby opportunity to study the physical mechanisms that drive these processes. Rapid changes in the highly-stressed magnetic fields of solar flares lead to large-scale energy release of up to ~10 ergs per second. These explo...

Based on the important effect of catalysts plasma-catalytic system, CM/Z5 catalyst prepared by incipient-wetness impregnation method is used for non-thermal plasma catalysis toluene removal. The low-temperature produced dielectric barrier discharge. Toluene removal performance with single investigated variation in experimental parameters. Results indicate that increase discharge length, selecti...

The local measurement of the island width w, around the resonant surface, allowed a direct test of the extended Rutherford model [P. H. Rutherford, PPPL Report-2277 (1985)], describing the evolution of radiation-induced tearing modes prior to disruptions of tokamak plasmas. It is found that this model accounts very well for the observed exponential growth and supports radiation losses as being ...
