The plots were oriented perpendicular to the drainage channel so that one half of each plot faced north and the other faced south. We also restrict our attention to propagation perpendicular to the magnetic field. The fir st is considered in the plane of the magnetic field while the second is perpendicular to it. In the presence of external magnetic field, the electron and the ions cannot move freely in the direction perpendicular to the lines of forces. In astrophysics, ring-type distributions can be found, for example, at quasi-perpendicular shocks [6]. Here this applies to the two directions that span the perpendicular subspace. Clearly, the data shows that the transition-dipole moments of these two transitions are perpendicular with respect to each other. Relativistic effects are known to be important in magnetized thermal plasmas near perpendicular propagation, even when they would otherwise be considered weak. The motion of the electrons takes place in a plane perpendicular to the cylinder axis. If the guess is a vertex then the planes are the ones that contain this vertex and are perpendicular to one of the edges. On the other hand, vector u2 describes a direction perpendicular to u1 that is used by the robot to avoid obstacles. In these simulations, the coordinate of particle motion was chosen to be perpendicular to the flat surface of the electrode. In this paper, the steady periodic electrostatic wave in a weak perpendicular magnetic field is considered within the framework of kinetic theory. Figure 5 depicts the initial and final ion core distribution function, showing significant energization in the perpendicular plane for both types of simulation. In this section, we consider the parallel motion (15) and the coupling between the parallel and perpendicular modes. The direction of observation was perpendicular to the axis of the injected beam. The low-frequency magnetic fluctuations induce motion of ions in the direction perpendicular to the ambient magnetic field. In a two-dimensional case a planar body can only move on a plane and rotate around the axis perpendicular to the plane. A problem with this slicing perpendicular to the nominal trajectory is that the nominal trajectory is not known (yet). The polarization vector of the massive transverse photon hence is perpendicular to the propagation direction, an expected result. The important feature of this model is to introduce the polytropic laws for the pressure components parallel and perpendicular to the magnetic field. The propagating wave packets assume a conical shape where the parallel group velocity is more than the perpendicular one. In a stationary plasma, gyrophase organization may drive unstable waves parallel as well as perpendicular to the background magnetic field. Besides the parallel wave propagation, our study also includes perpendicular wave propagation. Assuming a non-relativistic three species electron-positron-ion plasma, the counterstreaming instability is investigated for waves propagating parallel and perpendicular to a homogeneous background magnetic field. Another parameter is the maximum value of the perpendicular magnetic field component. In this case, the field has only a radial component at = 0, so that field and flow are initially perpendicular. We have also defined v and v to be the velocity components parallel and perpendicular to the ambient magnetic field. We investigate particle acceleration by strong lower-hybrid turbulence produced by the relaxation of an energetic perpendicular ion ring distribution. We find that there is only one mode of propagation in the perpendicular case that also exists for the parallel-propagation case. The polytropic laws are considered for the pressure components in directions parallel and perpendicular to the magnetic field. Seedling performance was measured on two (5-m wide) perpendicular transects through the extended gap area. Structures such as myelin sheaths, axonal membranes, and micro-filaments cause the water diffusion to be slower perpendicular to axons than parallel to them. The direction of the minimum axis is the radial line perpendicular to the strike of the foliation. One is polarized in the plane of the paper of figure 8, the other perpendicular to with respect to the plane of the this. Only for relatively strong horizontal gradients were instabilities perpendicular to these preferred. Again, the magnitude of the pressure is proportional to the perpendicular distance from the surface to the curve. Ideal pure shear is characterized by a stretching eigenvector parallel to the shear zone boundaries, and a perpendicular shortening eigenvector. If found so, the robot's orientation is directed along the line perpendicular to the intersecting edge in outward direction of the object (envelope). A flexible jointed link is attached to its rotational joint moving perpendicular to the horizontal plane, and its other joints are fixed. The tack-welded reinforcement had a known size and orientation perpendicular to the weld seam but had an unknown absolute position measured in the weld direction. By means of a perpendicular hung from the center between the two nails, this will be divided into equal parts. The first plane was perpendicular to the last extraction grid and the second was parallel to it. The primary entrained shocklet should be well resolved in experiment because it is perpendicular to the z-axis. The pole of the first of these - actually the middle sphere in the complete model - is perpendicular to a plane that bisects the zodiacal belt. I define this transition region by the perpendicular gradient of crab burrows that ranges from 0 to 1 m-2. The string was positioned perpendicular to the declivity, which is the usual direction of the prevailing wind. To test this assumption, a t-test was run on the perpendicular distances taken for visually located birds. We can also solve equation ei ej = 0 for to get a generator with the directions of two lines from different sets which are perpendicular. Now consider a case where r is given along with w, a vector perpendicular to the cylinder axis. The plots below 2600 m had to be placed at some distance from the perpendicular line due to topography. Three transects perpendicular to forest edges were established at three study sites, and six plots per transect were located 0-300 m from edges. The horizontal axis is cor tical distance perpendicular to the stripes; the ver tical axis is eccentricity. The latter situation would invoke a strong magnetic pressure gradient, leading to a pinch effect perpendicular to the external magnetic field lines. The perpendicular and parallel motions of electrons play equally important roles in the nonlinear interaction. The surfaces of the microbioids and background are not planar or perpendicular to the beam. The microscope perpendicular to the micropipette monitors the movement of the bead towards or away from the glass substrate on the microscope stage. All b-strands from a given molecule lie approximately in the same plane perpendicular to the long axis of the fibrils. Then we obtain the magnetic field effects on the plasma discharge instabilities for the perpendicular propagation case in the following cases. We see that, for large wavenumbers, the maximum instability occurs for larger wavevectors perpendicular to the pump wavevector. The width of a quasi-perpendicular collisionless shock front is smaller than the convective ion gyroradius so that ions become demagnetized in the ramp. The one limiting feature of such a model is that any perpendicular scale lengths must be larger than the average ion g yroradius. At quasi-perpendicular shocks, counter-streaming ion flows and ring distributions are also formed. Furthermore, it is not possible to have a magnetic field component perpendicular to the current sheet. To describe this effect, one should take into account the perturbed perpendicular electric field. The interaction between the rotating disk and the magnetic field produces bipolar jets perpendicular to the disk. Here 'numerical diffusion' means the numerically induced contribution of (very large) parallel transport to transport in the perpendicular direction. The lower panels indicate that both parallel and perpendicular electric fields contribute to the energy multiplication. The main effect is that the mean magnetic field renders the turbulence quasi-bidimensional with a nonlinear transfer essentially perpendicular to its direction. The thermal conductivity in the direction of the magnetic field strongly dominates the thermal conductivity in the directions perpendicular to the magnetic field. The magnetic field of the same strength is thus assumed to be perpendicular to the flow velocity. Without loss of generality, we assume that the plasma flow velocity v is perpendicular to the shock interface. The contact sur face has "roughness", and the direction of the gravitational field being constant or pulsed is perpendicular to the sur face. Subsequently, the plasma expands perpendicular to the target surface onto the target as well as outward. The top views in (a) and (b) are oriented perpendicular to the helical axis and the bottom views are along the helical axis. When the magnetic field is perpendicular to the surface, surface waves with higher phase velocities are possible. Acceleration of particles by plasma propagating perpendicular to the magnetic field is of fundamental importance in laboratory space and astrophysical plasmas. They can be applied to the investigation of the relativistic perpendicular particle acceleration that may possibly occur in space plasmas.
