This paper describes a trial of the Canterbury GP After-Hours Service (CGPAHS), a GP staffed after-hours service within the Canterbury Hospital Emergency Department. It was decided not to continue the service beyond the twelve-month trial phase because the opportunity cost to do this was greater than existing alternative services. The efficiency of the service might have been improved had great...

Using a numerical implementation of the ADHMN construction, we compute the fields and energy densities of a charge three monopole with tetrahedral symmetry and a charge four monopole with octahedral symmetry. We then construct a one parameter family of spectral curves and Nahm data which represent charge four monopoles with tetrahedral symmetry, which includes the monopole with octahedral symme...
