Considering the importance of this subject, the aim of this study was to investigate the incidence and trend of accidents and injuries in Kurdistan Province. Methods: This cross-sectional study was conducted in Kurdistan Province, between 2010 and 2014. Data were...
Introduction Hysterectomy has been one of the most common surgical procedures in women Finland. We studied population-based trends hysterectomy and its indications from 1986 to 2017. Material methods A retrospective cohort was created Care Register for Health by identifying who had a 2017 calculating number Digital Population Data Services Agency. estimated incidence period age as well indicati...
The current discrepancy between the Hubble constant, H 0 , derived from local distance ladder and cosmic microwave background is one of most crucial issues in cosmology, as it may possibly indicate unknown systematics or new physics. Here, we present a novel non-parametric method to estimate constant function redshift. We establish independent estimates evolution by diagonalizing covariance mat...
In this research study the daily and annually trends of precipitation in the central Kavir basin of Iran during 1951- 2007. The pixel data of daily precipitation from APHRODITE’s data base with a spatial resolution of 0.25˚ have been used. The Mann-Kendall (MK) nonparametric test has been used for determining the precipitation trend in this area. The trends have been tested in 3 levels 90...
background & aim: the aim of the study was to define the epidemiological characteristics of most important infectious diseases in iran in recent decades. methods & materials: this was a situation trend analysis of infectious diseases (vector and water borne disease, and food borne diseases) in recent decades based on data availability. three significance levels were used for mann-kendall test (...
shift changes and heterogeneity analyses of hydro-climatic variables is very important in water resources planning and management. in order to shift changes and heterogeneity analyses of tmin and tmax, precipitation and discharge, 2, 7 and 7 stations was used over the 40 years (1972-2011), respectively. the results of annual tmin and tmax series showed that both of two stations had the signific...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
weather condition is one of the much effective factors in the principle of architecture and urbanization. so in this research long-term trend of effective climate elements in architecture of darab city including mean of minimum temperature, temperature mean, mean of maximum temperature, minimum relative humidity, maximum relative humidity, relative humidity mean, wind speed and sun hours in mon...
