Query: On the concave and convex solutions of mixed convection boundary layer
  approximation in a porous medium   In this paper we investigate the similarity solutions of a plane mixed
convection boundary layer flow near a semi-vertical plate, with a prescribed
power law function of the distance from the leading edge for the temperature,
that is embedded in a porous medium. We show the existence and uniqueness of
convex and concave solutions for positive values of the power law exponent.
