Abstract: A computer-implemented bone-implant system evaluation method for application of mesh-free analysis of a bone-implant system for evaluation of performance of a bone-implant system for an implant implanted within the bone structure at an anatomical site, said method comprising (i) receiving a set of bone structure data set, wherein set of bone structure data includes data indicative of the bone structure at an anatomical site; (ii) inputting an implant data set and inputting the position of the implant data set, wherein the implant is selected based upon the biomechanical requirements for the anatomical site and the position and of the implant data set is indicative of the position of the implant with respect to the anatomical site, wherein implant data set includes data representative of the geometry and materials properties of the implant; (iii) creating a bone-implant model, wherein said bone implant-model includes a mesh-free model of trabecular bone at the anatomical site wherein the bone-implant model is

Abstract: The present invention relates to a mop bucket (10) that comprises a floor (26) and side walls (22, 24) that project upwardly from the floor (26). The floor (26) and side walls (22,24) define an interior volume (28). The floor (26) opens into a cavity (32) that is provided in the interior volume (28). A wringer (50) can be suitably attached to the bucket (50) either within or above the interior volume (28). The cavity is suitably shaped to allow a wringer from a like mop bucket to be located in the cavity (32) when the like bucket is stacked on top of the mop bucket (10). This allows mop buckets to be easily stacked one on top of the other, in a space-efficient manner with the wringer attached.
