The unequivocal global warming has an explicit impact on the natural water cycle and resultantly leads to increasing occurrence of extreme weather events which in turn bring challenges unavoidable destruction urban supply system. As such, diversifying sources is a key solution building resilience An atmospheric harvesting can capture out air provide point-of-use source directly. Currently, seri...
Abstract Background and Objective: Quality control of drinking water is important for maintaining health and safety of consumers, and the first step is to study the water quality variables. This study aimed to evaluate the chemical and physical indicators, water quality variables and qualitative classification of drinking water stations and water sources in Boroujerd. Material and Methods...
Background and Objectives: Heavy metals enter water supply sources in different ways such as natural or artificial and when they enter the food chain and accumulate in tissues, they cause harmful effects on human health. Therefore, the aim of this study was to determine the concentration of heavy metals in drinking water sources in Karaj and compare it with national standards. Materials and Me...
We report the results of a search for 22GHz water maser emission in IRAS-bright galaxies, using the 100-m Effelsberg telescope. In particular, we present the details of four new maser detections (IC 342, NGC 2146, NGC 3556, and Arp 299) and follow-up interferometric studies. A comparison between water maser detection rates derived in the present study and those in previous similar surveys is al...
Background: Natural disasters are out of human control, often leading to loss of life and property, and particularly affecting public health. Natural disasters influence human lives in different ways. They may have severe, obvious, or hidden consequences. Therefore, the present study aimed at examining the environmental health condition of the cities affected by 2017 earthquake in Kermanshah Pr...
Water is an essential component of human living and crucial in metabolism, substrate transport across membranes, cellular homeostasis, temperature regulation, circulatory function. Access to quality water a critical concern any society. However, shortage remains the central problem many households universe, prompting people depend on sources that are considered unhealthy for consumption. The pr...
Water requirements in many large water supply systems are provided by mixing water withdrawal from surface and underground resources with different quantity and quality.Water supply from underground sources requires energy consumption and surface water resources are limited and unstable.The aim of this research is managing optimal supply of required water of system with minimum energy cost and ...
