objective: although the etiology of schizophrenia is unknown, it has a significant genetic component. ‎a number of studies have indicated that neuregulin-1 (nrg1) gene may play a role in the ‎pathogenesis of schizophrenia. in this study, we examined whether the rs2439272 of nrg1 ‎is associated with schizophrenia and its negative symptoms in an iranian population.‎ method: rs2439272 was genotype...

this paper investigates the lateral vibration of single-layered graphene sheets based on a new theory called doublet mechanics with a length scale parameter. after a brief reviewing of doublet mechanics fundamentals, a sixth order partial differential equation that governs the lateral vibration of single-layered graphene sheets is derived. using doublet mechanics, the relation between natural f...

Sulfate scale deposition (BaSO4, CaSO4, and SrSO4) is a common problem in oilfield operations around the world, which causes significant formation damage during production and injection activities. This paper presents the results of an experimental study on the permeability reduction of porous media due to sulfate scale deposition. A set of experiments were cond...
