The aim of this study was to analyse what factors affect Health-Related Quality of Life (HRQoL) in patients undergoing cholecystectomy, and to assess the feasibility of SF-36 as a HRQoL instrument in a patient register. METHODS The SF-36(More)
Let f k (n) be the maximal number of edges of a simple graph on n vertices without k connected subgraph. W. Mader started to investigate the order of magnitude of this function. The rst results on f k (n) are due to W. Mader who proved that (3k ? 4)=2(n ? (k ? 1)) f k (n) (1 + 1= p 2)(k ? 1)(n ? (k ? 1)), assuming that n is large enough. He also conjectured(More)
