in this study, amine functionalized kit-6 silica mesoporous magnetite nanocomposite (nh2-mmnc) was synthesized by chemical methods and used as an efficient and recoverable adsorbent for removal of ponceau 4r, as a toxic dye, from aqueous solutions. the synthesized nanocomposites were characterized by xrd, ft-ir, bet and sem instruments. the effect of various experimental parameters on the dye r...

With the increasing demands of high surface irregularities and machining of composites, conventional machining processes are now being replaced by high speed Computer Numerical Control (CNC) machines. In this paper aluminium silicate made from alloying aluminium and silicon oxide made from rice husk are used. The machining of the alloy on CNC machine is carried out. In addition to speed, feed a...

The present paper envisages the multi-response optimization of certain process parameters like total sugars concentration, C/N ratio and incubation time on rhamnolipid yield, surface tension reduction, biomass formation and substrate utilization, in rhamnolipid production by a Pseudomonas aeruginosa mutant strain grown on clarified blackstrap molasses, under L9 orthogonal array in Taguchi desig...

In this study, effect of square cutout and beam widths on eigenvalue buckling analysis beams is evaluated using finite element Taguchi methods. ANSYS software used to perform the analyses were conducted L9 orthogonal array with three control factors. Each factor has levels. The first considered as position whereas second was assumed widths. influence levels cutouts responses determined signal-t...

Abstract—In this study, lipase production has been investigated using submerge fermentation by Aspergillus niger in Kilka fish oil as main substrate. The Taguchi method with an L9 orthogonal array design was used to investigate the effect of parameters and their levels on lipase productivity. The optimum conditions for Kilka fish oil concentration, incubation temperature and pH were obtained 3 ...

The effects of geometric parameters on the mixing performance of a staggered herringbone mixer (SHM) with patterned grooves are numerically investigated. Combining use of the software package CFD-ACE+ and the Taguchi method provides a powerful and systematic approach for research on microfluidics. An orthogonal array L9(3(4)) is established for parameters introduced by the groove geometry; in t...
