  We present results of time evolution of oblique MHD plane shocks including
diffusive cosmic ray acceleration with backreaction on the plasma flows. The
simulations include self-consistent effects of finite Alfven wave propagation
and dissipation. From the computed cosmic ray particle phase space
distributions we calculate expected leptonic and hadronic emissions resulting
from interactions between the cosmic rays, magnetic fields, the thermal
particle population and relevant astrophysical photon fields.
