sentences:  Finally, we can define the basis representation of our solutions formula_34
  Note here, that formula_34 is not defined at the interface positions.Besides, prism bases are employed for planar-like structures, and are capable for 2-D/3-D hybridation.The conservation law is transformed into its weak form by multiplying with test functions, and integration over test intervals
  By using partial integration one is left with
  The fluxes at the interfaces are approximated by numerical fluxes formula_39 with
  where formula_41 denotes the left- and right-hand sided limits.
