This study was carried out on Rosetta branch water and 3 drains (El-Rahawy, El-Soble El-Gezira) that discharging wastewater into it, to assess the Water Quality Index (WQI) of their waters. investigation performed during period starting from winter 2017 summer 2018. The mean annual averages WQI values were good poor for irrigation (up 55) very aquatic life 97) at stations exposed discharged bra...

The aim of this paper is to study the high order difference scheme for the solution of a fractional partial differential equation (PDE) in the electroanalytical chemistry. The space fractional derivative is described in the Riemann-Liouville sense. In the proposed scheme we discretize the space derivative with a fourth-order compact scheme and use the Grunwald- Letnikov discretization of the Ri...
