Abstract Background and objectives: Halo interference around antibiogram disc is one of the problems seen in Agar media. This study aimed at applying graded plate method to reduce this problem. Material and Methods: Forty-eight millimeter plates, before putting disc, were graded and the location of discs was determined. Instead of full disc, we used half-disc and then compared the haloe interfe...
A validation study in order to evaluate the efficiency of the inductively coupled plasma optical emission spectrometry (ICP-OES) in the analysis of minor elements (Manganese, Chromium, Copper, Iron and Titanium) in aluminium alloys was carried out. Aluminium casting samples were obtained from addition to aluminium baths of compressed powder compacts of each alloying element and aluminium (minit...
DRI production in tunnel furnaces sometimes encounters an incomplete degree of reduction. A model is required to tackle heterogeneous reaction rates, crucible heat transfer, and oxide morphology. Herein, a three-phase proposed based on mass conservation kinetics, describe the reduction hematite magnetite crucibles. The was implemented via Fortran program using finite volume discretization, resu...
