background: although stabilization ponds and lagoons are suitable treatment processes due to simplicity of operation and low per capital costs, the effluents of these systems have too high of a total suspended solids concentration to be discharged into receiving waters. this problem is mainly caused by algae. in this study, an electro-coagulation reactor was examined to re­move algae from the f...

we explore electro-catalytic properties of a system consisting of platinum and palladium nanoparticles dispersed over a nanotubular self-organized tio2 matrix. these electrodes prepared by electroess and microemulsion of palladium and palladium nanoparticles on to tio2 nanotubes, respectively. titanium oxide nanotubes were fabricated by anodizing titanium foil in ethylene glycol (eg) fluoride-c...

Based on the optical characteristics of PLZT (Lead Lanthanum Zirconate Titanate) electro-optic ceramic, two kinds of electro-optical deflectors, triangular electrode structure and optical phased array technology, are studied in detail by using transverse electro-optic effect. Theoretically, the electro-optic deflection characteristics and mechanisms of the deflectors are analyzed; experimentall...

the electro-osmotic consolidation is a method to improve geotechnical properties of soft clayey soils. the feasibility of electro–osmotically induced consolidation can be examined through the soil coefficient of electro–osmotic permeability (ke) and the electro–osmotic coefficient of water transport (ki). using an electro-osmotic testing cell, ke and ki parameters were measured in urmia lake we...

Evaluation of the Academic Preparedness and Final Performance of Students of Electro-Techniques Field in Technical and Vocational Schools A.A. Khallaaghi, Ph.D. E. Ghaasemi Pooyaa, Ph.D. To determine the extent of the electro-techniques students' preparedness in order to assess their success in learning the practical skills and attitudes prescribed by the curriculum, a cluster sam...

Free vibration of a simply-supported magneto-electro-elastic doubly-curved nano-shell is studied based on the first-order shear deformation theory in the presence of the rotary inertia effect. To model the electric and magnetic behaviors of the nano-shell, Gauss’s laws for electrostatics and magneto statics are used. By using Navier’s method, the partial differential equations of motion are red...

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...

this study aimed to determine the relationship between suturing and electro-cautery methods of post-tonsillectomy homeostasis in imam khomeini hospital- kermanshah. an analytical study was performed on admitted patient's profiles from 2002-2004. data collection sheet was applied to extract all variables. descriptive and inferential statistics were used for data analysis. during that period 915 ...

OBJECTIVE Analysing the fundamental methodological aspects which should be considered when drawing up calibration procedure for electro-medical equipment, thereby permitting international standard-based accreditation of electro-medical metrology laboratories in Colombia. METHODS NTC-ISO-IEC 17025:2005 and GTC-51-based procedures for calibrating electro-medical equipment were implemented and t...
