Query: Wiggly Strings in Linearized Brans-Dicke Gravity   The metric around a wiggly cosmic string is calculated in the linear
approximation of Brans-Dicke theory of gravitation. The equations of motion for
relativistic and non-relativistic particles in this metric are obtained.
  Light propagation is also studied and it is shown that photon trajectories
can be bounded.
