Query: On the Energy-Momentum Densities of the Cylindrically Symmetric
  Gravitational Waves   In this study, using Moller and Tolman prescriptions we calculate energy and
momentum densities for the general cylindrically symmetric spacetime metric. We
find that results are finite and well defined in these complexes. We also give
the results for some cylindrically symmetric spacetime models.
