This paper presents the micro-finishing of bevel gears by electrochemical-mechanical finishing (ECMF) process under different experimental conditions of current, rotating speed of workpiece and electrolyte concentration. These different experimental conditions are planned on the basis of box behnken design (BBD) design of experiments (DOE) technique of response surface methodology (RSM). An emp...

The natural coagulant Moringa oleifera (MO) is considered to be an efficient coagulant with some advantages over chemical coagulants. Fluoride removal, using MO seed extract was investigated. The influence of MO dosage, initial F concentration, and pH were determined and modeled using the Box-Behnken design response surface methodology. With a constant initial F concentration, it was found that...

Rhizomucor tauricus is used in the production of lipase, after several cycles it is disposed off as biological waste. A new biosorbent material fungus, Rhizomucor tauricus was immobilized, used as an adsorbent for removal of Nickel (II) and for optimization Box-Behnken design used by statistica 6.0. The time required to reach equilibrium was found to be 4 hours. The optimized concentration is 6...

In the present study, statistically based experimental design was applied for the optimization of bacteriocin production by Lactobacillus plantarum ATM11 isolated from goat slaughter house soil. Seven variables were chosen for Plackett-Burman design, in which three variables were screened as influencing factors: yeast extract, Tween 80 and K2HPO4. These three factors were subsequently optimized...
