introduction: patient safety culture is an important part of improvement in the safety of health care. knowing its present status is required for development of safety culture. the present study aimed to evaluate the current status of patient safety culture in hospitals of three central provinces of iran. method: the present cross-sectional study was performed in teaching hospitals of tehran, a...

parameters such as future precipitation, temperature, snowfall, and runoff were modeled using precis regionalclimate modeling system in iran with the horizontal resolutions of 0.44×0.44°c in latitude and longitude under sresa2 and b2 scenarios. the dataset was based on hadam3p during the periods of 1961-1990 and 2071-2100. theoverall precipitation error of the model in the period of 1961-1990 w...

We studied the behavior of earthquake network using HEALPix spherical pixelization and square cells methods. In first method, geographical region is divided into isolatitude rhombic-spherical same areas method. second we equal cells. To construct a network, if an happens in cell, that cell will become node, two nodes be connected with edge for successive events. The built from Iran’s seismic da...

hyrcanian forests in northern slope of alborz support high bird richness and abundance same as central of europe. in this study, efficiency of different methods including fixed-width transect, variable-width transect, fixed-radius point count and variable circular plot samplings were compared in order to present the most reliable methods for surveying and monitoring of diurnal forest birds in f...

natural ecosystems provide many goods and services for human beings via their multiple functionalities. one of these important functions is the role of natural ecosystems in regulation of hydrologic cycle and increasing the infiltarion and retention of water in soil context and preventing from water runoff which may cause in unfavorable consequences like soil erosion and flooding. quantificatio...

Interferometric Synthetic Aperture Radar (InSAR) capability to detect slow deformation over terrain areas is limited by temporal decorrelation, geometric decorrelation and atmospheric artefacts. Multitemporal InSAR methods such as Persistent Scatterer (PS-InSAR) and Small Baseline Subset (SBAS) have been developed to deal with various aspects of decorrelation and atmospheric problems affecting ...
