Scalar Field Entropy in Brane World Black Holes
  A semiclassical calculation of entropy of a scalar field in the background of a class of brane world black holes (BWBH) is carried out in the presence of a brick wall cutoff when the 5D-bulk induced \textquotedblleft tidal charge" has generic or extreme values.
