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...

Previous research has shown an ‘interindividual-intergroup discontinuity effect’: intergroup interactions generally lead to less cooperative outcomes than interindividual interactions. We replicated the discontinuity effect in the deterministic prisoner’s dilemma, but we found that groups were more cooperative than individuals in a stochastic version of the game. Three major factors, greed, fea...

We investigate the asymptotic behavior, as ε tends to 0+, of the transverse displacement of a Kirchhoff-Love plate composed of two domains Ωε ∪ Ω − ε , contained in the (x1, x2)-coordinate plane and depending on ε in the following way. The first domain Ωε is a thin strip with vanishing height hε (in direction x2), as ε tends to 0+. The second one Ωε is a comb with fine teeth, having small cross...
