Es werden Wellen in einem quasi-neutralen Gas untersucht, das Ionen und Elektronen enthält und genügend kalt ist, so daß die thermischen Bewegungen vernachlässigt werden können. Außerdem werden Zusammenstöße zwischen den Teilchen vernachlässigt, jedoch nicht die Trägheitseffekte des elektrischen Stromes. Die nicht-linearen Gleichungen für unendlich ausgedehnte, ebene Kompressionswellen, die sic...

this paper presents a model of a catchment area in northwest of iran. the researchers have studied ajichai basin which is located in the east part of orumiyeh lake, located at the longitude of 47 52’ e to 45 32’ e and the latitude of 37 26’ n to 38 30’ n. the researchers have chosen the data from tabriz upper air station which is the only one in the area. the research data are seven instability...

The presence of chaotic transients in a nonlinear dynamo is investigated through numerical simulations the 3D magnetohydrodynamic equations. By using kinetic helicity flow as control parameter, hysteretic blowout bifurcation conjectured to be responsible for transition dynamo, leading sudden increase magnetic energy attractor. This high-energy hydromagnetic attractor suddenly destroyed boundary...
