A measurement of strange baryon and antibaryon production in Pb-Pb collisions has been carried out by the NA57 experiment at the CERN SPS, with 40 and 158 A GeV/c beam momentum. Results on Λ, Ξ and Ω hyperon yields at mid-rapidity in the most central 53% of Pb-Pb collisions at 40 A GeV/c are presented and compared with those obtained at higher energy, in the same collision centrality range.The Λ and Ξ − yields per unit rapidity stay roughly constant while those of Ω − , Λ, Ξ + and Ω + increase when going to the higher SPS energy. Hyperon yields at the SPS are compared with those from the STAR experiment in √ s N N = 130 GeVAu-Au collisions at RHIC.

Rheumatology patients and professionals identified a relative lack of information for patients. There was wide interest in the provision of more information, with value placed on the provision of material in different languages, at an educational resource centre. This work has been used to develop the facilities currently offered at the Birmingham Arthritis Resource Centre. Further research is needed to investigate the effectiveness of the provision of good quality information to patients with arthritis.
