Query: Pair of associated Schouten-van Kampen connections adapted to an almost
  paracontact almost paracomplex Riemannian structure   There are introduced and studied a pair of associated Schouten-van Kampen
affine connections adapted to the paracontact distribution and an almost
paracontact almost paracomplex Riemannian structure generated by the pair of
associated metrics and their Levi-Civita connections. By means of the
constructed non-symmetric connections, the basic classes of the manifolds with
the considered structure are characterized. Curvature properties of the studied
connections are obtained. A family of examples on a Lie group is constructed.
