Flow channel design on bipolar plates has a direct effect on Proton Exchange Membrane (PEM) fuel cell performance. It has been found out that the flow field design has a deterministic role on the mass transport and water management, and therefore on the achieved power in PEM Fuel cells. This study concentrates on improvements in the fuel cell performance through optimization of channel dimensio...

Background and Purpose: Patients with Bipolar I Disorder recurrence experiences mood variation between manic and depression during the time. Hence, that is need to the longitudinal study on Bipolar Disorder patients. This study aims to evaluate the effective factors on Bipolar I Disorder frequent recurrence in 5 years longitudinal study using generalized estimation equations (GEE) m...

objective: several studies show co morbidity of anxiety disorders amongst patients with bipolar and unipolar disorders. it is associated with an intensification of symptoms, insufficient treatment response, non recovery, poor functional outcome and suicidality. the aim of this study was to show the frequency of anxiety disorders comorbidity and the relationship between comorbidity and suicide a...

introduction: substance abuse/dependency is one of the most important comorbidity in bipolar patients. therefore, recognizing the patterns of substance use is valuable in treatment and management of patients. this study was conducted to determine patterns of substance abuse among bipolar patients who were hospitalized in an educational hospital. methods : this was a descriptive-analytical study...

conclusions these findings support that the careful evaluation and prospective following of the psychopathology of children of parents with bipolar disorder are critical for early identification and treatment. results there were statistically significant differences between children of parents with and those without bipolar disorder regarding attention deficit hyperactivity disorder, opposition...

objective: bipolar i disorder is a common disorder with a complex etiology. a genetic approach is gaining increasing importance in this disorder. the dysbindin gene, located at 6p22.3 is considered a susceptibility gene for schizophrenia. certain genotypes of dysbindin are thought to be associated with other psychoses such as bipolar disorders. this study intends to assess the association in pr...

We disclose a novel high pressure design, non-destructive structural analysis and fabrication of bipolar plate composites (BPC) that are highly conductive yet mechanically flexible. Here we report the highest electrical conductivity 221 S cm?1 BPC by tailoring graphitic structure carbon nanomaterials their functional attributes through enhancement in-plane as well mechanical strength; another a...
