the surface water chemistry of thiruvananthapuram museum lake was carried out in the period of february 2013 to january 2014. correlation study of the parameters and overall ccme wqi (canadian council of ministers of the environment water quality index) was also prepared in the study for the lake water. the parameters analysed are cations such as ca2+, na+, mg2+ and k+ and the anions like po4-,...

The Chilia branch is the north of Danube River at Romania-Ukraine border in Delta; it a complex system with economic and ecological values. surface water quality major concern monitoring programs have been developed national international level. objective this study was to evaluate different sampling points from mouth discharge Black Sea. assessment done individual level taking into account nut...

Abstract The quality of the drinking water source reservoirs has always been a research hotspot. However, few have studies focused on over relatively long period with time series analysis. In this paper, based and hydrological data from 2010 to 2020, considering 8 parameters, CCME-WQI analysis was used explore interannual seasonal changes in Weishui Reservoir. Furthermore, main factors affectin...

The cytochrome c maturation protein CcmE is an essential membrane-anchored heme chaperone involved in the post-translational covalent attachment of heme to c-type cytochromes in Gram-negative bacteria such as Escherichia coli. Previous in vitro studies have shown that CcmE can bind heme both covalently (via a histidine residue) and non-covalently. In this work we present results on the latter f...

Biogenesis of c-type cytochromes in alpha- and gamma-proteobacteria requires the function of a set of orthologous genes (ccm genes) that encode specific maturation factors. The Escherichia coli CcmE protein is a periplasmic heme chaperone. The membrane protein CcmC is required for loading CcmE with heme. By expressing CcmE (CycJ) from Bradyrhizobium japonicum in E. coli we demonstrated that hem...

Present work is aimed at assessing Water Quality Index (WQI) for groundwater of Upper Pincha Basin, Chittoor District, Andhra Pradesh. This has been carried out by collecting groundwater samples and subjecting them to comprehensive physico-chemical analysis. Results obtained were compared with standard values recommended by WHO for drinking and public health. For computing WQI, eleven parameter...

The Water Quality Index (WQI) is an important parameter in describing the water resources' suitability for human uses and one of most effective methods quality indicative assessing utilization health ecosystems. WQI Canadian Council Ministers Environment (CCME) was used study to describe Shatt al-Arab Basrah Southern Iraq, its drinking use. data analyzing river samples were adopted from five st...

Groundwater pollution in karst areas is often the result of interaction hydrogeological characteristics and human activities. In this study, a chimeric evaluation system groundwater vulnerability load was constructed, contamination risk intuitively displayed using map. The study area located Qiannan, typical Southwest China. mainly calculated PLEIK model. Pollution source evaluated classificati...

Good, clean, healthy and safe water quality is very important for the survival of humans living creatures on earth. The application index (WQI) method at a certain location time can provide an assessment quality. This study took samples in middle zone Jambi Province which Regencies: Tebo, Bungo, Sarolangun Batanghari order to test using Potential Hydrogen (pH), temperature, Dissolved oxygen (DO...
