On the Role of Electric Charge and Cosmological Constant in Structure
  Scalars
  The physical meaning of structure scalars is analyzed for charged dissipative
spherical fluids and for neutral dust in the presence of cosmological constant.
The role played by such factors in the structure scalars is clearly brought out
and physical consequences are discussed. Particular attention needs to be paid
to the changes introduced by the above mentioned factors in the inhomogeneity
factor and the evolution of the expansion scalar and the shear tensor.
