Size reduction processes, which encompass crushing and grinding, represent a significant part of the capital as well operating cost in ore processing [...]

We report on three cases of subtrochanteric femoral fractures during trochanteric intramedullary nailing for the treatment of femoral shaft fractures. Trochanteric intramedullary nails, which have a proximal lateral bend, are specifically designed for trochanteric insertion. When combined with the modified insertion technique, trochanteric intramedullary nails reduce iatrogenic fracture comminu...

A coronal fracture of a femoral condyle (Hoffa fracture) is an unusual injury and there are only a handful of reports discussing it. We report a case of a 52-year-old worker who fell from a height, suffering lower limb injuries, including a Hoffa fracture with comminution, and had problems with malunion during the postoperative period. Clinicians should be aware that rehabilitation programmes n...

We reviewed 57 adult patients at an average of 37 months after early internal fixation for displaced fractures of the distal humerus. Two-thirds had intercondylar (Müller type C) fractures, and one-third had articular comminution (type C3). A chevron olecranon osteotomy was used, with early active movement after fixation. Results were good or excellent in 76% with an average range of movement o...

This paper describes the use of an evolutionary algorithm to solve an engineering design problem. The problem involves determining the geometry and operating settings for a crusher in a comminution circuit for ore processing. The intention is to provide a tool for consulting engineers that can be used to explore candidate designs for various scenarios. The algorithm has proved capable of derivi...
