In our previous work, the effect of use of a water soluble CDI/NHS system as nontoxic cross-linking agent on fabrication of gelatin nanoparticles was investigated. In this research, the effect of variation in some synthetic parameters of gelatin nanoparticles cross-linked by CDI/NHS system such as type of gelatin and formulation of cross- linking agent on their size and distribution was examine...

Several indices have been used in the past for the assessment of the performance of water distribution systems. In this paper the performance of water distribution systems is evaluated using the resilience index and the failure index proposed by Todini (2000). The method is demonstrated through the analysis of a real world application, the water distribution system of the town of Sofades in Cen...

Abstract In this paper, information entropy was proposed to measure water quality reliability in a distribution system (WDS), which had been applied evaluate hydraulic the WDS. evaluation, residual chlorine is representative of quality, and first-order decay model usually adopted. The (R) based on (WQE) improved (Rd) (IWQE) were compared for three networks. method developed EPANET toolkit MATLA...

in order to investigate distribution status of heavy metals in cropping systems of water logging and dry farming, an experiment was conducted as split-plot arrangement based on randomized complete block design with three replications in research field of sari agricultural science and natural resources university. a paddy-soil considered for water logging system and the planted field with vegeta...

For any agency dealing with the design of the water distribution network, an economic design will be an objective. In this research, Central Force Optimization (CFO) and Differential Evolution (DE) algorithm were used to optimize Ismail Abad water Distribution network. Optimization of the network has been evaluated by developing an optimization model based on CFO and DE algorithm in MATLAB and ...

The present study encompasses a new method to simultaneous analysis, design and optimization of Water Distribution Systems (WDSs). In this method, analysis procedure is carried out using Charged System Search (CSS) optimization algorithm. Besides design and cost optimization of WDSs are performed simultaneous with analysis process using a new objective function in order to satisfying the analys...

background & aims of the study: corrosion and scaling play undesirable effects on transmission and distribution system of drinking water. the aim of this study was to assess the corrosion and scaling potential of drinking water resources in babol city. materials and methods: totally, 54 water samples were collected from 27 wells in spring and autumn. calciu m hardness, ph, total alkalinity, tot...

Introduction: Piped water systems are considered to be the gold standard for drinking water according to the Joint Water Monitoring Study. However, poor maintenance of distribution pipes, intermittency of water supply, and sewage water intrusion have contributed to a number of water-borne disease episodes in developed and developing countries. Methods: This study investigated the risk burden r...
