Query: Large time behaviour for a nonlocal diffusion - convection equation
  related with the gas dynamics   In this paper we consider a model that involves nonlocal diffusion and a
classical convective term. Using a scaling argument and a new compactness
argument we obtain the first term in the asymptotic behavior of the solutions.
