The simultaneous estimation of Atorvastatin Calcium (ATS) and Olmesartan Medoxomil (OLM) in bulk pharmaceutical dosage forms, a new, quick, cost-effective Reverse Phase High Performance Liquid Chromatography (RP-HPLC) method has been developed. experimental design was used to achieve multivariate optimization the RP-HPLC conditions. Three independent variables were create mathematical models: A...

The countersinking process is affected by many factors including the tools and workpiece parameters. Some forming phenomena such as knife-edge affect quality of countersunk hole. Up to now, kinds research rely mainly on experiments which lead poor difficult control this process. In paper, a proposed numerical optimization developed obtain normalized This approach based response surface method (...

xanthan gum is an extracellular polysaccharide produced by various xanthomonas species such as x. campestris . the objective of present study was to investigate the influence of different carbon and nitrogen sources on xanthan gum production by x. campestris . using an experimental response surface methodology (rsm) complemented with a central composite design (ccd), the impact of peptone, lact...

osmotic dehydration under discontinuous reduced pressure is one of the new methods of preparation fruits and vegetable processing with in view of good health. processing of foods at high temperatures used to cook them can cause the formation of carcinogenic substances like acrylamide, and this risk remains even if the trans-fat is removed. the low temperatures employed in this method resulted i...
