Standard electronic drum pads are equipped with one piezoelec­ tric sensor that converts stick strikes to electronic pulses which are measured and used to trigger pre-recorded samples or other sounds. Advanced models can measure the amplitude of this pulse and adjust the volume of the resultant sample or even select a different sample en­ tirely. The state of the art electronic drums are equipp...

BACKGROUND The aim of this study was to report the patients who were admitted to our hospital with upper extremity injuries due to threshing machine, to determine the most appropriate classification, to estimate the treatment modalities, and to discuss the prevention methods. METHODS Twenty-five patients who had suffered injuries sustained by a threshing machine were retrospectively investiga...

– Mixing of two fractions of a granular material in a slowly rotating two-dimensional drum is considered. The rotation is around the axis of the upright drum. The drum is filled partially, and mixing occurs only at a free surface of the material. We propose a simple theory of the mixing process which describes a real experiment surprisingly well. The dependence of the mixing time on the drum fi...

Significant increases in rice production can be obtained in sub-Saharan Africa (SSA) by increasing rice grain yield in existing production systems, expanding rice harvested area, and reducing harvest and postharvest losses. However, availability of labour at critical times is often a major constraint, and this situation is aggravated by the effects of the HIV/AIDS pandemic. Delays during harves...
