lateral and anterior displacements of mandible may cause malocclusion. the aim of this study was to determine the prevalence of these displacements in a population of 597 childrens age 12 in mashhad secondary schools. displacment of mandible was shown to be in 11.8 percent of the population (6.2 percent anterior and 5.6 percent lateral displacement).anterior displacement of mandible was diagnos...

Submerged granular flows through an orifice were investigated numerically in the context of sinkhole occurrences during a flood due to presence underground conduits. To account for fluid-solid interaction at pore-scale, we use numerical modelling that combines Discrete Element Method (DEM) solid particles with Lattice Boltzmann (LBM) fluid dynamics. The setup studied is submerged discharge from...
