The fir st term on the right-hand side of (26), representing spatial disper sion, leads to diffractional divergence in the absence of nonlinear terms. The fir st of these terms is exclusively responsible for instability in our canonical problem (see below). The belt of coniferous forest is dominated by evergreen pine, spruce, larch and fir trees. Normally the fir st term in this expression dominates. The answer to this question cannot be ascertained at fir st sight even on physical grounds. For higher flux densities, the fir st caviton depth again increases, leading to stronger mode conver sion processes. These results indicate a qualitative similarity between the results for the fir storder mode here and the simulations with periodic boundary conditions. This is the fir st step of our modeling mentioned in the above discussion. Let us define a continuous field r(r) with continuous fir st derivatives, which represents a virtual displacement of the fluid. The fir st is the increasing group velocity of the laser pulse and the other is the relativistic retur n currents. As a fir st approximation, the plasma jet can be treated as a quasi-stationary problem within the computational time-step of the combustion cycle. Since in (14) the momentum p corre+ sponds to the resonant particles, we can neglect the fir st term of (2). The fir st two express that total momentum and charge neutrality must be maintained, and therefore do not impose any new restrictions. Let us designate this magnetic shell as the plasmapause of the fir st type. For completeness, we fir st derive the equations gover ning the dynamical response of the density in the presence of a laser pulse as follows. The fir st term in (4) is due to the electron axial velocity; we call this term the axial velocity-induced self-magnetic field. The long-wavelength modes fir st seem to be damped; however, later they show an algebraic growth in time, before ultimately the exponential viscous damping wins. The fir st is considered in the plane of the magnetic field while the second is perpendicular to it. Consider fir st what happens in the inner region y < a containing the background shear velocity. The electron is fir st accelerated to vy 0.15c before it is detrapped. In this case we find exact solutions in terms of elliptic integrals of the fir st kind. Here the fir st term is a purely collective part. The general principles of transport in toroidal plasmas are fir st of all discussed. These examples are from corpora and from sources on the web.
