Abstract Introduction Group and save (G&S) testing is often performed prior to emergency appendicectomy. However, there are no standard national guidelines regarding the routine use of preoperative G&S. We a Trust Audit review need for G&S appendicectomy in order recommend new guidelines. Method Retrospective all patients that underwent at Chelsea Westminster Hospital between Octobe...

The ? system has been studied in the reaction ? p ! ? p at 18 GeV=c. A large asymmetry in the angular distribution is observed indicating interference between L-even and L-odd partial waves. The a 2 (1320) is observed in the

By the application of a linear mass spectrum to a composite system of both the pseudoscalar and scalar meson nonets, we find three relations for the masses of the scalar states which suggest the qq̄ assignment for the scalar meson nonet: a0(1320), K ∗ 0 (1430), f0(1500) and f ′ 0(980).
