Two-dimensional, nonlinear, Hall-magnetohydrodynamical ~MHD! numerical simulations are used to investigate the scaling of the rate of forced magnetic reconnection in the so-called Taylor problem. In this problem, a small amplitude boundary perturbation is suddenly applied to a tearing stable, slab plasma equilibrium. The perturbation is such as to drive magnetic reconnection within the plasma. ...

2014 Electromagnetic plane wave momentum transfer to an inhomogeneous plasma slab has been evaluated for an arbitrary reflecting and absorbing plasma density profile based on Euler’s equation of motion but including a ponderomotive term. In the limit where the plasma density follows a step function, the Fresnel formulae for the coefficient of reflectivity have been obtained for both normal and ...

Vertical slab electrophoresis in polyacrylamide gels was used to monitor changes in lactate dehydrogenase (LDH) isozymes in plasma of white rats during bacterial infection and endotoxin poisoning. Peritoneal infection with Francisella tularensis and Salmonella typhimurium and administration of S. typhimurium endotoxin stimulated significant increases in plasma LDH-5. Rates of change in enzyme a...

We derive simple sets of equations to describe the microwave response of a thin film of magnetized hydrogen plasma in the presence of carbon nanotubes, which were grown by ironcatalyzed high-pressure disproportionation (HiPco). By considering the interference effects due to multiple reflections between thin plasma film interfaces, we present the effects of the continuously changing external mag...

We present new tomographic models of the Nazca slab under South America from 6°S to 32°S, and from 95 km to lower mantle (895 km) depths. By combining data from 14 separate networks in the central Andes, we use finite-frequency teleseismic P-wave tomography to image the Nazca slab from the upper mantle into the mantle transition zone (MTZ) and the uppermost lower mantle on a regional scale. Our...

We investigate momentum transport in the Hamiltonian electrostatic gyrokinetic formulation in Dubin D H E et al [1983 Phys. Fluids 26 3524]. We prove that the long wavelength electric field obtained from the gyrokinetic quasineutrality introduces a non-physical momentum source in the low flow ordering.

Observations show that small-amplitude prominence oscillations are usually damped after a few periods. This phenomenon has been theoretically investigated in terms of non-ideal magnetoacoustic waves, non-adiabatic effects being the best candidates to explain the damping in the case of slow modes. We study the attenuation of non-adiabatic magnetoacoustic waves in a slab prominence embedded in th...
