       h said-related nonlinear wave effects E. Mishin, Air Force Research Laboratory, Space vehicles Directorate, Hanscom AFB, MA, United States We present recent observations from the Cluster spacecraft that have shown that excitation of lower hybrid/fast magnetosonic waves plays the fundamental role in SAID Frontiers in Dusty Plasmas This chapter takes a look at a number of effects of the dust. Wave energy propagating at oblique angles to the magnetic field in an increasing density gradient can be very efficiently damped by resonance absorption processes in a dusty plasma. The chapter focuses on the time evolution of the pair correlation

Magnetic reconnection, the merging of oppositely directed magnetic fields that leads to field reconfiguration, plasma heating, jetting and acceleration, is one of the most celebrated processes in collisionless plasmas. It requires the violation of the frozen-in condition which ties gyrating charged particles to the magnetic field inhibiting ://

The model treats cosmic rays in a kinetic PIC way, while the ions and electrons of the thermal plasma are described through MHD equations.

This subject will be treated within the context of the expanding solar wind and the most meaningful advances in this research field will be reported emphasizing the results Hence if V is the volume of a mass M of liquid bounded by a surface whose area is S, the integral M = f f f pdx dydz, (I) where the integration is to be extended throughout the volume V, may be divided into two parts by considering separately the thin shell or skin extending from the outer surface to a depth within which the density and other properties of the liquid vary with the depth, and Simulations of Solar Wind Turbulence.

To simulate the evolution of turbulence in a spherically expanding solar wind, we have solved the inviscid MHD equations using a fourth-order flux corrected transport (FCT) algorithm [Boris and Book, ; DeVore, ; Zalesak, ].
