there have been many productive methods developed so far for optimization of multiple response surface (mrs) problems. this paper tends to review the most seminal approaches in mrs and discuss the strength and weakness of each of the approaches through existing aspects in mrs. a numerical example is included to compare results by different methods. finally some of the prominent areas for future...

saturated fat consumption increases the risk of both coronary and cancer diseases. therefore, fat reduction in uf-feta cheese (≈ 45% fdm) is favorable but, unfortunately, it has some negative effects on the texture and sensory characteristics of the cheese. in this research, response surface methodology was employed to study the probably improving effects of wpc80 (0-20 gr kg-1), lecithin (0-2 ...

treated sea water is the most significant source of water and surfactant floods. the various chemicals employed in treatment plants should be compatible with surfactant systems. based on surface tension experiments, the activity of these chemicals is examined over a wide range of concentrations in different solutions, including distillated water, sea water by using three types of surfactant mix...

in some conditions, to avoid deterioration and field losses of soybean seeds (glycine max merr.) from weathering at end of the season, farmers start to harvest seeds with a high moisture content and so, careful post-harvest drying would be required to maintain the physiological quality of seeds. response surface methodology (rsm) was used to optimize the operating conditions of soybean seed dry...

objective(s): response surface methodology (rsm) by central composite design (ccd) was applied to statistically optimize the preparation of rutin-quercetin (ru-qr) dual drug loaded human hair keratin nanoparticles as well as evaluate the characteristics. materials and methods: the effects of three independent parameters, namely, temperature (x1:10-40 c), surfactant (x2: sds (1), sls (2), tween-...

inulin is widely used in functional foods throughout the world for its health-promoting and technological properties. helianthus tuberosus is cultivated widely in the northern part of iran. helianthus tuberosus can be a valuable source of inulin. to optimize conventional extraction of inulin, various combinations of time, temperature, and solvent: solid ratio, were used. in this research, a ser...

problematic dyes extensively used in different industries such as textile, paper, food, plasticsand cosmetics have undesirable environmental effects. white rot fungi demonstrating effective extracellularenzyme system, which is capable of degrading dyes and various xenobiotics. the aim of this study was tooptimize decolorization of reactive blue 19 (rb19) dye using phanerochaetechrysosporium. a ...

formaldehyde in small quantities is commonly analyzed by spectrophotometric methods. one of the most-commonly used spectrophotometric techniques for this purpose is based on the reaction with chromotropic acid. because of its simplicity, sensitivity, selectivity and its low cost, it is still widely used. investigations for replacing the concentrated sulfuric acid with other acids or using more ...

a box-behnken design with three replicates was used for preparation and evaluation of eudragit vancomycin (vcm) nanoparticles prepared by double emulsion. the purpose of this work was to optimize vcm nanoparticles to improve the physicochemical properties. nanoparticles were formed by using w1/o/w2 double-emulsion solvent evaporation method using eudragit rs as a retardant material. full factor...
