Query: Weak Lensing, Shear and the Cosmic Virial Theorem in a Model with a
  Scale-Dependent Gravitational Coupling   It is argued that, in models where the gravitational coupling is
scale-dependent, predictions concerning weak gravitational lensing and shear
are essentially similar to the ones derived from General Relativity. This is
consistent with recent negative results of observations of the MS1224, CL2218
and A1689 systems aimimg to infer from those methods the presence of dark
matter. It is shown, however, that the situation is quite different when an
analysis based on the Cosmic Virial Theorem is concerned.
