Current Penetration and Plasma Disruption

Comparison of current disruption and magnetic reconnection

We examine similarities and differences between the concepts of current disruption (CD) and magnetic reconnection (MR). Both concepts have been invoked to account for explosive phenomena that involve energy transformation from magnetic field to charged particles. Similarities of these two concepts include (1) the occurrence of breakdown in magnetic connectivity, (2) magnetic energy as the prima...

Clinical application of plasma derived medicines: current situation and future trend

Treatment of striae distensae combined enhanced penetration platelet-rich plasma and ultrasound after plasma fractional radiofrequency.

BACKGROUND Striae distensae (striae alba) is a challenging cosmetic problem for which various treatment modalities have been applied. However, the treatment of striae distensae has not been satisfactory. OBJECTIVES This study was done to evaluate the effectiveness and the safety of enhanced penetration of platelet rich plasma with ultrasound after plasma fractional radiofrequency for the trea...

Mechanisms of plasma disruption and runaway electron losses in tokamaks

Based on the analysis of data from the numerous dedicated experiments on plasma disruptions in the TEXTOR tokamak mechanisms of the formation of runaway electron beams and their losses are proposed. The plasma disruption is caused by strong stochastic magnetic field formed due to nonlinearly excited low-mode number MHD modes. It is hypothesized that the runaway electron beam is formed in the ce...

Vesicle accumulation and exocytosis at sites of plasma membrane disruption

Plasma membrane disruptions are resealed by an active molecular mechanism thought to be composed, in part, of kinesin, CaM kinase, snap-25, and synaptobrevin. We have used HRP to mark the cytoplasmic site of a mechanically induced plasma membrane disruption. Transmission electron microscopy revealed that vesicles of a variety of sizes rapidly (s) accumulate in large numbers within the cytoplasm...
