Embedding of two de-Sitter branes in a generalized Randall Sundrum   scenario
  In this work it is studied a generalization of Randall Sundrum model. It is obtained new behaviors of {\it warp factor}, constraints in that the strong brane has tension of positive sign and, new relations between the coupling constants $\kappa_4$, $\kappa_5$ and between the Higgs and Planck masses.
