Azo dyes are widely used in textile industries. Removal of the color from textile waste water is a striking issue. To curb this issue, biological treatment can be employed rather than physicochemical processes. In this work, Bacillus subtilis is used to degrade the reactive dye – RED M5B. It is found that decolorization was due the action of enzyme peroxidase produced by the organisms during it...

In this paper, we present our vision for a framework to facilitate computationally-based aerospace vehicle design by improving the quality of the response surfaces that can be developed for a given cost. The response surfaces are developed using computational fluid dynamics (CFD) techniques of varying fidelity. We propose to improve the quality of a given response surface by exploiting the rela...

For decades, difference scores have been widely used in studies of congruence in organizational research. Although methodological problems with difference scores are well known, few viable alternatives have been proposed. One alternative involves the use of polynomial regression equations, which permit direct tests of the relationships difference scores are intended to represent. Unfortunately,...

Ultrasonic technology and response surface methodology (RSM) wereused for optimization of extraction of condensed tannins from the leaf, acron, gland and gall of oak. Three independent variables such as solvent percentage (%), temperature (°C) and time (min) were studied. Effect of methanol concentration was found to be significant on all responses. Optimal ultrasonicassisted extraction (UAE) c...

The ultrasound-assisted (UA) soybean oil methanolysis using KOH as a catalyst was studied at different reaction conditions in a microreactor. Box–Behnken experimental design, with three variables, was performed and the effects of three reaction variables i.e. reaction temperature, catalyst concentration and the methanol-to-oil molar ratio on fatty acid methyl ester (FAME) yield were evaluated b...

background and objectives: psychrotrophic bacteria can produce enzymes at low temperatures; this provides a wide biotechnological potential, and offers numerous economical advantages over the use of mesophilic bacteria. in this study, extracellular protease production by psychrotrophic rheinheimera sp. (km459533) was optimized by the response surface methodology. materials and methods: the cult...

This article presents an algorithm for constructing orthogonal Latin hypercubes, given a fixed sample size, in more dimensions than previous approaches. In addition, we detail a method that dramatically improves the space-filling properties of the resultant Latin hypercubes at the expense of inducing small correlations between the columns in the design matrix. Although the designs are applicabl...

Amine is one of candidate solvents that can be used for CO2 recovery from the flue gas by conventional chemical absorption/desorption process. In this work, we analyzed the impact of different amine absorbents and their concentrations, the absorber and stripper column heights and the operating conditions on the cost of CO2 recovery plant for post-combustion CO2 removal. For each amine solvent, ...

This paper presents results obtained from simulating a service system with process oriented simulation methodology. To make the service system responsive and efficient, the SCOR modeling idea is incorporated to build the simulation model. Awesim is a process oriented simulation modeling methodology and so is the Supply Chain Operations Reference (SCOR), developed by supply chain council. A dent...
