introduction : the aim of this study was to compare obsessive-compulsive disorder (ocd) comorbidity in early and late onset bipolar i disorder and to explore the pattern of obsessive symptoms in these two groups. methods : a total of 100 inpatients with early and late bipolar disorder were admitted in the child, adolescent and adult psychiatric ward. they were recruited to the study through con...

Introduction: Bipolar Spectrum Disorders include a variety of mood disorders from bipolar II disorder to conditions characterized by hyperthymic mood states. It has been suggested that psychosocial factors also play an important role in bipolar disorders, in this study we have used social network analysis in order to better understand the social positions of those affected by bipolar spectrum d...

background : lack of insight in patients with bipolar i disorder has been associated with poor course and clinical outcome and compromised therapeutic compliance. therefore, it is important to evaluate insight and use more specialized scales such as mood disorder insight scale (mdis) in these patients. our objective in this study was to assess validity and reliability of persian version of mdis...

natural vibration analysis of plates represents an important issue in engineering applications. in this paper, a new and simplify method for vibration analysis of circular and rectangular plates is presented. the design of an effective robust controller, which consistently attenuates transverse vibration of the plate caused by an external disturbance force, is given. the dynamics of the plate i...

The interpretation of the surface charge pattern spacers in gas-insulated transmission lines (GIL) is an interesting and important research topic, which requires a comprehensive understanding behaviors at physical interfaces. Here, we report charging phenomenon presence metal particles inside direct current (DC) GIL. spherical particle on spacer appears as dotted discontinuously distributed spo...

In this study, a C/TiC nanocomposite coating has been prepared by magnetron sputtering technology and vacuum heat treatment on titanium surface, which is used for bipolar plates (BPs) in proton exchange membrane fuel cell (PEMFC). This was characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), photoelectron spectroscopy (XPS), Raman spectroscopy, electrochemical testing inte...

The cells of many embryonic tissues actively narrow in one dimension (convergence) and lengthen in the perpendicular dimension (extension). Convergence and extension are ubiquitous and important tissue movements in metazoan morphogenesis. In vertebrates, the dorsal axial and paraxial mesodermal tissues, the notochordal and somitic mesoderm, converge and extend. In amphibians as well as a number...
