Identification of MHD compressible modes in interstellar plasma with
  synchrotron emission polarization
  We provide a procedure for identification of dominating compressible and
Alfvenic MHD modes or isotropic turbulence in synchrotron emission polarization
maps of Galactic objects. The results for the region of North Galactic Pole,
Orion molecular cloud complex and the star-forming complex Cygnus X are
presented.
