Introduction: Monitoring and controlling water resources and using health risk assessment approaches for water pollutants are essential for health promotion programs. This study aims to determine the water quality status and its spatiotemporal variation across the Kan River Basin, explore the interrelationship between surface and groundwater quality indices, and assess the nitrate health risk i...

multivariate process capability indices (mpci) show how well a manufacturing process can meet specifica-tion limits when quality characteristics enclose a relative correlation. process capability is an important and commonly used metric for assessing and improving the quality of a production process. when quality charac-teristics of a product are correlated then an attractive comes close to mpc...

Background: Iran is located within the dry and semi dry regions, thus almost 90% of the required water is secured via the use of groundwater. Owing to the increasing pollution of water resources, this study was performed to evaluate water quality pollution indices for heavy metals (As, Zn, Pb and Cu) contamination monitoring in Toyserkan Plain during spring and summer in 2012. Methods: A tot...

application of ethephon is an effective way in increase of grape fruits quality. in this study the effect of preharvest application of ethephon solution at four levels (0, 150, 250 and 300 mg/l)and application time at two levels (10-20% and 50-70% of berry coloring), were evaluated on quality indices of ghizil uzum grape cultivar at harvest time. evaluated indices were soluble solids content, t...

objectives this study aims to detect the effect of selected aerobic exercises on sleep quality in non-athlete middle-aged women. materials and methods fifteen non-athlete middle-aged women participated in this study, all of them suffered from insomnia. pittsburgh questionnaire was used for determining sleep quality in this sample. four indices including sleep duration, sleep disturbance, sleep ...

The paper is devoted to solution of some problems in nuclear power station generating unit intellectual control systems using genetic algorithms on the basis of control system model development, optimizations methods of their direct quality indices and improved integral quadratic estimates. Some mathematical vector models were obtained for control system multicriterion quality indices with due ...
