We report a 38-year-old male with a nonunion followed by plate breakage after volar plating of a distal radius osteotomy. Volar locking plates have added a new approach to the treatment of distal radius malunions, due to a lower morbidity of the surgical approach and the strength of the final construction, allowing early mobilization and return to function. Conclusion. Plate breakage is an unco...

This paper describes a two-dimensional computer simulation study of the impact induced breakage of brittle solid particles. The work started as an attempt to understand the effect of impact velocity on the induced breakage and in particular to explain why there is a shift in the slope of the size distribution at large impact velocities. The results indicate that the observed breakage pattern is...

in this study the wavelet neural network (wnn) and artificial neural network (ann) were used to simulate barley breakage percentage in combine harvester. the models have been trained using the same data conditions. air temperature, thresher cylinder speed, distance between thresher cylinder and concave (back and forth) and the percentage of barely moisture were as the input variables. the resul...

In multi-seam mining, the residual coal pillar (RCP) in upper gob has an important influence on layout of roadway lower seam. At present, few papers have studied characteristics surrounding rock gob-side entry driving (GED) with different widths under RCP. This research contributes to improving recovery rate extra-thick seam this condition. The main contents were as follows: (1) mechanical para...

Abstract: Discrete mathematical model was developed for analysis and design of the continuous grinding mill-classifier systems. In the model, the mixing of the material to be ground by the axial dispersion model, the breakage kinetics by the first order breakage law, and the classifier by a usual classification function are described. This model is the basic of computer simulation. Computer pro...
