introduction: the number of systematic reviews and meta-analyses published in iran has increased significantly in recent years. writing these articles based on internationally accepted guidelines is one of the most important factors effective on their structural quality. this study aimed to assess the abstract of iranian systematic reviews and meta-analyses indexed in scopus. methods: this stud...

the relative impacts of different types of land use on the surface water quality are yet to be ascertained and quantified. in this paper, the influence of different types of land use on surface water quality is investigated. rain events samples from different land use in the central plateau, iran, were analyzed for major ions. statistical analyses were employed to examine the statistical relati...

the wide availability of data on air pollutant emissions, the knowledge already achieved on theset of chemical and photochemical reactions in the troposphere, the ability to access real time weatherconditions at the local scale that determine the transport and transformation of gases and aerosol, now make it possible to obtain credible and reliable predictions, retrospective analyses and/or fut...

a methodology is presented in this paper to find optimal location and dosage of chlorine injection in water distribution networks. the objective is to minimize the chlorine consumption while keeping the residual chlorine at each node within the standard range. unfortunately because of wrong water quality management in water distribution networks in many parts of the world, many problems such...

objectives: there have been numerous attempts to construct non-monetary indices of social and economic satisfaction by combining in a single statistic a variety of different factors that are thought to influence human well-being. method: the concept of quality of life (qol) as an aggregate measure of people’s well-being in a certain country, region, or social stratum. the economist intelligence...
