Study of the ground water quality in Hodeidah is an essential ingredient for a healthypopulation. In this research, study of drinking water samples for eight water sources wells in theQuti field has been achieved. The purpose was to a certain the quality of water from thesesources, the physical properties such as pH, electrical conductivity (EC) and total dissolvedsolids (TDS), showed the varia...

This article deals with the determination of temperature distribution, displacement and thermal stresses of a rectangular plate having nonhomogeneous material properties with internal heat generation. The plate is subjected to sectional heating. All the material properties except Poisson’s ratio and density are assumed to be given by a simple power law along x direction. Solution of the two-dim...

Microbial desalination cells (MDCs) hold great promise for drinking water production because of potential energy savings during the desalination process. In this study, we developed a continuously operated MDC--upflow microbial desalination cell (UMDC) for the purpose of salt removal. During the 4-month operation, the UMDC constantly removed salts and generated bio-electricity. At a hydraulic r...

the taguchi method was applied as an experimental design to determine optimum conditions for colour removal from azo dyes solutions containing remazol yellow g by electrocoagulation (ec) using iron and steel electrodes as anode and cathode, respectively. an orthogonal array (oa9) experimental design that allows to investigation the simultaneous variations of four parameters (initial remazol ye...

The present paper sought to assess some physico-chemical parameters above permissible guidelines of irrigation water standard, the study was carried during establishment Ecotourism Park. field survey design used and it accompanied by laboratory tests analyze levels in both seasons (dry season wet seasons) for bodies as well groundwater. physical chemical analysed were Sodium Adsorption Ratio (S...

groundwater makes up an important part of global freshwater resources, though it is often threatened by overuse of natural resources along with abundant production of wastes in modern society. this study aims to investigate the removal of three heavy metals including nickel, cadmium, and lead from groundwater via electrocoagulation, a suitable method for treatment of water-soluble compounds, de...

This study aims to analyze the chemical composition of Lioua’s groundwater in order determine geological processes influencing and origin its elements. Therefore, chemometrics techniques, such as multivariate statistical analysis (MSA) time series methods (TSM) are used. Indeed, MSA includes a component (PCA) cluster (CA), while autocorrelation (AA), supplemented by simple spectral density (SDA...

For many years it has been commonly accepted that electroconvection (EC) as primary instability in nematic liquid crystals for the "classical" planar geometry requires a positive anisotropy of the electric conductivity, sigma(a), and a slightly negative dielectric anisotropy, epsilon(a). This firm belief was supported by many experimental and theoretical studies. Recent experiments, which have ...
