A boundary element formulation is presented for analysing the surface bone remodelling. The formulation is based on sensitivity analysis and utilises design parameters which are related to the shape of the bone. An application of the method to the modelling of bone ingrowth into a slot of an implant is presented.
In June 1866, Patrick Manson (1844-1922), newly qualified in medicine at Aberdeen University, arrived in Formosa (Taiwan) to begin a career in the service of the Chinese Imperial Maritime customs. His five years there, and subsequently at Amoy on the Chinese mainland, set in train a sequence of events that has been called 'the birth of the science of tropical medicine'. For it was there that Manson began his solitary painstaking studies of the filarial larvae of elephantiasis, and of mosquitoes transmitting filarial infections. It was there that he first realised and acknowledged his own shortcomings in diagnosing and treating the 'tropical diseases' affecting his Chinese patients. These shortcomings were shared by many British colleagues, sent to outposts of the Empire, with no formal knowledge of diseases of hot climates, which did not then form part of the curriculum in British medical schools.

The purpose of this study is to test the hypothesis that convenience for the physician plays a role in the rate of cesarean section performed because of dystocia. Three time periods were defined (night, 12 midnight to 7:59 AM; day, 8 AM to 5:59 PM; evening, 6 PM to 11:59 PM) based on the work commitments and daily routines of the obstetrician. Rates of cesarean section for dystocia were determined for each of the three time periods. An evening peak in the cesarean section rate is partially but not entirely explained by an evening increase in the proportion of patients in prolonged labor. When patients were stratified according to labor duration (less than 12, 12 to 15, and greater than 16 hours), a persistent evening excess in the rate of cesarean section for dystocia was observed for patients whose labor duration was less than 16 hours. Although this is interpreted as being consistent with the hypothesis of physician convenience, the magnitude of this effect on the overall rate of cesarean section for dystocia is small.
