Introduction: Ambient temperature is considered as a factor affecting on the body's metabolism, So that increase or decrease ambient temperature to the range thermoneutral zone (TNZ) (This temperature is 20.3°C to 23°C for covered people) lead to body metabolic changes, and maybe effective on the increase or reduce the prevalence of obesity. Our aim of this study was to review ...
Objective: To conduct a systematic review about the use of virtual reality (VR) for evaluation, treatment and/or rehabilitation of patients with schizophrenia, focused on: areas, fields and objectives; methodological issues; features of the VR used; viability and efficiency of this resource. Methods: Searches were performed about schizophrenia and virtual reality in PsycINFO, Academic Search Co...
Background and Objective: The Hospital expenditures and the growing the elderly population had an important role in increasing the health system expenditures. The purpose of this study was to determine the cost pattern of health services in Iranian elderly people. Materials and Methods: All descriptive and analytic studies done regarding the cost-benefit model of health services in the elderly...
We survey both academic and proprietary models to examine how macroeconomic and systematic risk effects are incorporated into measures of credit risk exposure. Many models consider the correlation between the probability of default (PD) and cyclical factors. Few models adjust loss rates (loss given default) to reflect cyclical effects. We find that the possibility of systematic correlation betw...
Self-calibration techniques for analyzing cluster counts rely on using the abundance and the clustering amplitude of clusters to simultaneously constrain cosmological parameters and the relation between halo mass and its observable mass tracer. It was recently discovered that the clustering amplitude of halos depends not only on halo mass, but also on various secondary variables such as halo fo...
A new 7-beam 6−7 GHz receiver has been built to survey the Galaxy and the Magellanic Clouds for newly forming high-mass stars that are pinpointed by strong methanol maser emission at 6668 MHz. The receiver was jointly constructed by Jodrell Bank Observatory (JBO) and the Australia Telescope National Facility (ATNF) and allows simultaneous coverage at 6668 and 6035 MHz. It was successfully commi...

Virtual reality technology enables people to become immersed in a computer-simulated, three-dimensional environment. This article provides a comprehensive review of controlled research on the effectiveness of virtual reality (VR) distraction for reducing pain. To be included in the review, studies were required to use a between-subjects or mixed model design in which VR distraction was compared...
Background and Objectives: Iran has carried out a series of surveys based on the Global school-based student health survey (GSHS) referred to as the CASPIAN. The aim of this paper was to compare the methodology and tools of CASPIAN surveys and to propose recommendations and suggestions for future implementations. Methods: The data of this systematic review study were gathered from the World...
