The aim of this study was to prepare orally disintegrating tablets (ODTs) containingdexamethasone (DEX) by direct compression method with sufficient hardness and rapiddisintegration time. In order to save time, money, and human resources in designing andimprovement of formulation, the statistical software Design Expert is used. Box–Behnkenresponse surface methodology was applied to evaluate and...

since the analysis of complex services systems by using mathematical modeling techniques, with considering the random patterns prevailing in them, is so difficult or probably impossible, improvement guidelines are often followed based on the experts' experiences using qualitative methods. in the present paper, by employing a discrete event computer simulation methodology, criminal trial sy...

Honing is a process for finishing surfaces to obtain smooth surface. This process is used for final polish of inner parts such as engines cylinders. Optimizing this process has always been a big challenge for mass production of cylinder blocks of internal combustion engines. Honing process has some variable parameters, thus to get their optimum rates the automobile cylinders were tested. In thi...

The research investigates synthesized Nano-structured PbO2 using ball milling. The structure and morphology of the samples were determined in the process of milling by means of XRD and SEM. The size of particles was estimated through DLS analysis. The TEM image of the synthesized powder verifies the achievement of Nano dimensions. Design and analyses of the results using Taguchi methodology rev...

A well-designed and constructed experiment will be robust under questioning, and will focus criticism on conclusions [1], rather than potential experimental errors [2]. A sound experimental design should follow the established scientific protocols and generate good statistical data [3]. As an example, experiments on an industrial scale can cost millions of dollars. Repeating the experiment beca...
