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...

Comparative study of chiral liquid crystalline (S)-(1)-4’-(1-methylheptylcarbonyl) biphenyl-4-yl 4-[4-(2,2,3,3,4,4,4-heptafluorobutoxy)butyl-1-oxy] benzoate (4HH) and (S)-4’-(1-methylheptyloxycarbonyl)biphenyl-4-yl 4-[4-(2,2,3,3,4,4,4-heptafluorobutoxy) butyl-1-oxy]-2,3-difluorobenzoate (4FF) is performed by complementary methods. For 4HH melting the low-temperature crystal phase subsequent col...

The basic electro-kinetic process is defined by forced/induced movement of target pollutants in soil/sand medium under applied electric field low strength between electrodes of opposite polarities. There are several specific mechanisms that contribute to this movement of pollutants. However, one study suggested that the most important ones are electro-osmosis, electro migration, and electrophor...

Though graphitic carbons are commercially available for various electrochemical processes, their performance is limited in terms of various electrochemical activities. Recent experiments on layered carbon materials, such as graphene, demonstrated an augmented performance of these systems in all electrochemical activities due to their unique electronic properties, enhanced surface area, structur...

BACKGROUND Annually, large quantities of dyes are produced and consumed in different industries. The discharge of highly colored textile effluents to the aquatic environments causes serious health problems in living organisms. This paper investigates the performance of each of the electro-oxidation and electro-reduction pathways in the removal of reactive red 120 (RR120) from synthetic textile ...
