Electrically conductive zirconia tungsten carbide composites are attractive materials for manufacturing precision components by electrical discharge machining due to their high strength, toughness and conductivity. In this study, nanocomposite ceramics with a ytterbia samaria co-stabilized 1.5Yb-1.5Sm-TZP matrix 24–32 vol.% dispersion were manufactured spark plasma sintering (SPS) at 1400 °C 15...

gas motion within the cylinder is one of the major factors that control the combustion process in spark ignition engine. it also has significant impact on heat transfer. both the bulk gas motion and the turbulence characteristics of the flow are important and governing the overall behavior of the flow. an arrangement for obtaining a stratified charge, using port injection, is proposed for a cur...

Introduction: One of the most important human senses is vision, which its loss is causing many primary and secondary complications for physical and psychological health such as difficulties in static and dynamic balance. This study aimed to compare the effect of 8 weeks of Spark and Frenkel exercises training on the static and dynamic balance in blind people. ...
