Self–similar and charged spheres in the diffusion approximation
We study spherical, charged and self–similar distributions of matter in the diffusion approximation. We propose a simple, dynamic but physically meaningful solution. For such a solution we obtain a model in which the distribution becomes static and changes to dust. The collapse is halted with damped mass oscillations about the absolute value of the total charge.
متن کاملSelf diffusion in mixtures of charged spheres
2014 We have used the Forced Rayleigh Scattering technique to measure the self diffusion constant of the two separate species of charged polystyrene spheres mixed in a strongly interacting suspension. For a few large spheres diffusing in a larger density of smaller spheres, we find that the diffusion constant is simply related by Stokes law to the total viscosity of the suspension. For the same...
متن کاملSelf–similar and Charged Radiating Spheres: an Anisotropic Approach
Considering charged fluid spheres as anisotropic sources and the diffusion limit as the transport mechanism, we suppose that the inner space– time admits self–similarity. Matching the interior solution with the Reissner– Nordström–Vaidya exterior one, we find an extremely compact and oscillatory final state with a redistribution of the electric charge function and non zero pressure profiles.
متن کاملthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
