The aim of the study was to find the optimum combination of materials and thicknesses to provide a tough, damage resistant multi-layer system with numerical methods to restore the damaged teeth. Extended Finite Element Method (XFEM) was used to assess the critical loads for the onset of damage modes such as radial cracks and plastic deformation in dental prostheses, which consist of a brittle o...

A bstract Coherence violation is an interesting and counter-intuitive phenomenon in QCD. We discuss the circumstances under which occurs observables sensitive to soft radiation arrive at conclusion that almost all such hadron colliders will violate coherence some degree. illustrate our discussion by considering gaps-between-jets observable, where super-leading, then we generalise other observab...

English has an important role as a global language, especially in the era of globalization. To master English, there are four types proficiency skills such listening, speaking, reading, and writing. Speaking is simplest form communication life. However, teaching techniques Indonesia used by teachers generally unattractive monotonous. Students only provided with textbooks conventional materials;...
