Introduction: Due to water scarcity and increased water consumption during the past years, the importance of water in terms of transmission of diseases, as well as Iran's climate, groundwater aquifers are known as the most important resources of drinking water supply. Using the Water Quality Index (WQI) is considered as strong managerial tool for decision making in water resource management. Th...

We calculate the baryon asymmetry of the Universe which would arise during a first order electroweak phase transition due to minimal standard model processes. It agrees in sign and magnitude with the observed baryonic excess, for resonable KM parameters and mt in the expected range, and plausible values of bubble velocity and other high temperature effects. Research supported in part by NSF-PHY...

Karkheh river is located in southwestern of Iran. Industrial and agricultural activities around the river contaminate it through its path. Water quality modeling from upstream of Shoosh city to downstream was simulated by QUAL2K model. In this study, we investigated how best to manage the quality of Karkheh river to be done. Nine parameters including BOD, COD, DO, PH, turbidity, nitrate, phosph...

The Sinos River basin is located Northeast of the state of Rio Grande do Sul (29° 20’ to 30° 10’ S and 50° 15’ to 51° 20’ W), Southern Brazil, covering two geomorphologic provinces: the Southern plateau and central depression. It is part of the Guaíba basin and has an area of approximately 800 km, encompassing 32 municipalities. The objective of this study was to monitor water quality in the Si...

Genome-wide association studies (GWAS) facilitate largescale identification of genomic variants that are associated with complex traits. However, susceptibility loci identified by GWAS so far generally account for a limited fraction of the genotypic variation in patient populations. Predictive models based on identified loci also have modest success in risk assessment and therefore are of limit...

The primary task that is facing most developing countries the untreated disposal of wastewater into water bodies. In order to meet needs future generations, integrated resources should be managed within a sustainable method. This study illustrates assessment and judgment suitability Tigris River for drinking purposes using quality index (WQI) selection mostly significant WQ parameters affect de...

Abstract In this study, a customized WQI (Seoul water quality index, S-WQI) for urban rivers that can ultimately reflect their characteristics was developed by modifying and supplementing the existing Bascarόn calculation method through linkage with statistical methods such as factor analysis. We used data generated monthly at 17 monitoring networks (WQMNs) in Seoul 18 years, from 2002 to 2019....
