Abstract The aim of this study is to determine the Caracosh (Al-Hamdannia district) groundwater water quality index (CCME WQI). This was calculated by taking samples and putting them into a thorough physicochemical examination. For calculating WQI, following 9 parameters have been considered: pH, TDS, T. Alkalinity, hardness, Ca, Mg, Chloride, Sulphate Nitrate. WQI for these ranges from 25.19 9...

When comparing the average citation impact of research groups, universities and countries, field normalisation reduces the influence of discipline and time. Confidence intervals for these indicators can help with attempts to infer whether differences between sets of publications are due to chance factors. Although both bootstrapping and formulae have been proposed for these, their accuracy is u...
