A brief review of the theory contributions presented in the EC-18 Workshop is given. The covered spectrum of topics is quite broad including the electron cyclotron wave propagation physics as well the results of numerical modelling of transport and current drive.

I survey the parameter space of NAHE-based free fermionic heterotic string models. First, I discuss flat directions of the low energy effective field theories and show that D-flat directions need not be isomorphic to gauge invariant superpotential terms. Next, I review recent studies of three generation SU(3)C × SU(2)L × U(1)Y , SU(3)C ×SU(2)L ×SU(2)R ×U(1)B−L, SU(4)C × SU(2)L ×U(1)Y ′ , and fl...

background existence of fluoride in drinking water above the permissible level causes human skeletal fluorosis. objectives electrocoagulation by iron and aluminum electrodes was proposed for removing fluoride from drinking water. materials and methods effects of different operating conditions such as treatment time, initial ph, applied voltage, type and number of electrodes, the spaces between ...

in the present study, the treatment of tannery wastewater was performed by electrocoagulationmethod (ec) using aluminium and steel electrodes. response surface methodology (rsm) with three factors; current density (i), electrolysis time (t) and ph, with each factor at five levels, was used to optimize the factors for higher chemical oxygen demand (cod) and total suspended solids (tss) removal. ...

the performance of a plug flow electrocoagulation reactor for the treatment of cattle abattoir(slaughterhouse) wastewater was investigated. a cylindrical iron reactor was operated as a cathode at arecycling batch mode while three iron rods located at the center of the reactor were used as an anode. theeffects of different parameters, including the current density, the supporting electrolyte dos...

Abstract The current work investigated the efficacy of hybrid treatment process electrocoagulation and adsorption in removing hydroxyzine (HDZ) from polluted aqueous solutions. Response surface methodology (RSM) was used to optimize operating parameters based on sub-category central composite design (CCD). significance variables, interactions, quadratic effects through analysis variance (ANOVA)...

The characteristics of restaurant wastewater were investigated. High oil and grease contents were detected. Electrocoagulation was used to treat this type of wastewater. Different electrode materials and operational conditions were examined. Aluminum was preferred to iron. Charge loading was found to be the only variable that affected the treatment efficiency significantly. The optimum charge l...

OBJECTIVE To present our experience of endoscopic electrocoagulation of sphenopalatine artery for persistent posterior epistaxis despite conservative measures. METHODS Seven endoscopic electrocoagulation of sphenopalatine artery was done for four patients from early 2001 till the present for recalcitrant epistaxis despite conservative treatment. The basic principle of this surgical method is ...
