The viscosity is maximal when the vector of velocity is orthogonal to the vector of electricfield, and minimal when these vectors are parallel. The electricfield which accompanies the time change in the axial magnetic field also decreases from the outside to the inside. This means that a cross-field electricfield is produced by the dynamo effect of the cross-field particle drift or acceleration due to electrostatic waves. The amplification factor for the longitudinal electricfield is given and analyzed, as well as the transmission and reflection coefficients. The electricfield is disturbed and turbulent, which confine electrons at the tip. This depletion creates a negative electricfield, which decelerates the ions. However, in a void the comparatively higher ionization rate leads to an electricfield that is directed outward from the void center. This dip develops in a region where the ions experience rapid acceleration due to an abrupt increase in the electricfield. Further, we find that some particles in another positron bunch are accelerated by the parallel electricfield. The energetic electrons launched into vacuum made static longitudinal electricfield and the electricfield accelerated protons into vacuum. When the laser pulse propagates in plasmas, its transverse electricfield is converted into the longitudinal field of the plasma wave, which accelerates the particles. In conjunction with a strong longitudinal electricfield component, a natural acceleration channel has been demonstrated to exist for a laser beam in a vacuum. This cage can then be tracked or manipulated further downstream in the analysis using an electricfield. The particles can be moved by an alternating gas or liquid flow, as in chromatography, or by an alternating electricfield, as in electrophoresis. Both the magnetic and the electricfield are localized in a narrow domain elongated in the transverse direction. The probe reduces the local radial electricfield so that the beam magnetic force predominates. The electricfield with the inaccurate quasi phase matching would not change significantly because of the low conversion efficiency. Moreover, it also reduces the electricfield on electrodes and in gaps, which is preferable for electrical insulation. This dependence shows that the external electricfield intensity applied in our experiment does not affect the scaling low. In principle, an iteration procedure may be applied to evaluate the induced electricfield self-consistently. Consequently, the arginines are carried through the membrane electricfield, resulting in a conformational change which couples channel opening to membrane voltage. This term increases anomalously when the pump-wave amplitude tends to the threshold strength of the electricfield. The threshold of density which is used for electricfield calculation is increased by a factor of 10 from the original threshold. Note that the effect of any non-zero streaming is to introduce a dipole into the electricfield, far from the grain. The electron pressure tensor term also strongly violates the electron frozen-in condition and generates the reconnection electricfield at the reconnection point. Equations (12)-(15) represent the important conserved quantities of mass, momentum, the y component of the electricfield and entropy. It is possible to include the effect of a radial electricfield in this type of modelling. The presence of a radial electricfield has consequences for both the ripple loss mechanisms. To resonate with the oscillating electricfield in the interaction region, it must bear the same or be near the frequency of the electricfield. If this electricfield is weak, it causes conventional electric drift, but a strong enough electricfield results in free acceleration of the particle. The positive space charge of the ion layer near the cathode will shield the electricfield. Positrons are reflected along the magnetic field by the wave electricfield. Further, when an ion beam propagates obliquely to the external magnetic field, an induced electricfield has a component along the magnetic field. The quasistatic time variation of the electricfield amplitude makes it possible to use the 'direct initiation' mechanism to describe instability development. At this stage, it is not yet necessary to assume that the electricfield varies slowly in space. The presence of a strongly sheared electricfield also has some consequences for the kinetic equation. Control astrocytes were not exposed to an electricfield but, otherwise, they were treated identically. Plus (+) and minus(-) signs indicate the direction of the electricfield vector. Such type of charge separation would generate the electricfield inside the target. Ionization of atoms in an alternating electricfield. The driving electricfield imposed at the upstream boundary carries the plasma towards the current sheet and compresses it. It can be conjectured that in this case the electricfield is too weak to prevent breakthrough caused by the hydrodynamic dipole. Phase-space holes also have less spectacular observational counterparts, but equally important consequences on the development of the electricfield in the plasma. The corresponding charge separation also creates an electricfield which can accelerate ions to high energy. This large cloud extension increases the electricfield because the ion acceleration potential results applied to a lower target-electron cloud distance. The electricfield is generated in order to satisfy the current neutrality. The outgoing electrons experience strong electricfield produced by the separation between the slow moving heavy ions and the forward moving electrons. The transverse electricfield is maximum at r s0#2. The zero electricfield regulates injection of electrons abundantly available at the cathode surface, essentially controlling the diode current. Because the strong laser electricfield component is in the transverse direction, it may drive electrons from the laser center. We represent the electricfield as the sum of the incident and the reflected radiation. Effective electricfield, charge and potential can then be defined. Figure 1 shows the electricfield convergence processes. The electricfield goes to zero in the plasma and increases linearly near the wall. In this paper, we calculate the resulting electricfield explicitly. The result is used to determine the ratio of the harmonic component to the fundamental component for each part of the wave electricfield. The wave electricfield also consists of a steady-state part and an unstable part. Also, the poloidal electricfield can then be obtained from (13). As a consequence, a dissipative electricfield is generated that makes the current sheet locally unstable. Therefore, (2) cannot describe the screening of the static electricfield in this plasma. The induced electricfield turns the current away from the plate thereby reducing the normal component of current to zero a t the nonconducting surface. When the gel is subject to an electricfield (electrophoresis), the segments in the digest move down the gel, separating according to size. In this case, one observes a transverse bending of the density spikes by the electricfield lying in the simulation plane. This generation of electricfield by fast electrons has been considered by a number of authors. In three dimensions, we would expect a lower fast electron current density and hence a lower electricfield. This acts to deflect the electrons into the region of higher electricfield, increasing the field generation. The electricfield is decreased in the channel, and it is enhanced near the anode. It was shown that a nonuniformity of the electricfield forces the discharge to contract to the region of the increased electricfield. This force generates the radial space-charge electricfield, which points away from the laser propagation axis. Furthermore, we assume constant temperatures and a constant parallel electricfield across the discharge. We have in this paper shown how the parallel electricfield is built up on auroral field lines. Dynamics of a relativistic charged particle in a constant homogeneous magnetic field and a transverse homogeneous rotating electricfield. The equations for the electricfield and the velocity and pressure of the fluid are not coupled. The non-uniform electricfield induces the charge on the surface of the dust particle. In all practical cases an electricfield is used and it is often found that a critical field exists below which no distortion occurs. In reality, then, we expect a competition between this stabilising diffusion, and the steepening effect due to the electricfield. The apparent viscosity (the resistance to flow) in the direction orthogonal to the direction of the electricfield abruptly increases. The charged mobile liquid a t the interface moves in response to the applied electricfield. A further immobilization step, using gels or cross-linking agents, ensures that cells stay in place once the electricfield has been switched off. The ver tical scale gives the reflected electricfield in arbitrary units. The sharp edge of the nozzle makes the electricfield highest at the cathode. Inside the density cavity, a quasi-static electricfield is sustained by the small residual charge separation. A general expression for the spatiotemporal electricfield of the transition radiation is derived, and closed-form solutions for several special cases are given.
