Query: Pressure-temperature phase diagrams of selenium and sulfur in terms of
  Patashinski model   The pressure - temperature phase diagrams of Se and S are calculated. Both
melting and polymorphous phase transition are described in the frames of
statistical Patashinski model. The results are in good agreement with
experimental data of Brazhkin et. al.
