In this paper, a comparative study based on Finite Element Method has been established in order to investigate the effect of bipolar plate materials stress and temperature distribution proton exchange membrane fuel cell stack under functioning conditions. The analysis is conducted for three materials: Graphite BP, stamped uncoated stainless steel SS316L, Niobium coated SS316L. ICR (Interfacial ...

Introduction: According to the cumulative evidence, genes encoding GABA receptors inhibit neurotransmitters in CNS and are intricately involved in the pathogenesis of mood disorders. Based on this hypothesis, these genes may be expressed in bipolar patients. As a result, we evaluated the gene expressions of GABA-β3 and HT1D receptors to assess their associations with bipolar mood disorder....

• good electrical conductivity (>100 S cm 1 bulk conductivity), • high thermal conductivity (>20 W cm ), • high chemical and corrosion resistance, • mechanical stability toward compression forces, • low permeability for hydrogen, • low-cost material being processable with mass production techniques, • low weight and volume, and • recyclable materials. Two different kinds of materials have been ...

the effect of a distributed patch mass on the natural frequency of vibration of a laminated rectangular plate with simply supported boundaries is investigated. the third order displacement field of a composite laminated rectangular plate is defined using the two variable refined plate theory. equations of motion of the plate are obtained with the help of calculus of variation. parametric study ...

objective: bipolar disorder is a severe mental disorder, and its prevalence is around 1% to 2%. despite a vast literature around bipolar disorder, the reasons of its nonadherence and rehospitalization is still obscure. several symptoms of bipolar disorder include changes in activity level, cognitive abilities, speech, and vegetative functions, such as sleep, sexual activity, as well as aggressi...

ôbjectives: non-adherence limits the effectiveness of medications among patients with bipolar disorder. many studies have investigated the predicting factors of non-adherence. this paper aims to present the pattern of adherence in patients with bipolar ï disorder (bïd). methods: seventy six patients with bïd enrolled in a prospective study. the medication possession ratio (mpr) was used to eval...

The mitotic spindle is required for chromosome congression and subsequent equal segregation of sister chromatids. These processes involve a complex network of signaling molecules located at the spindle. The endocytic protein, clathrin, has a "moonlighting" role during mitosis, whereby it stabilizes the mitotic spindle. The signaling pathways that clathrin participates in to achieve mitotic spin...
