the present study was aimed to develop and validate a high performace liquid chromatography method for determination of thiocolchicoside and dexketoprofen trometamol in combined dosage form. the proposed hplc method utilizes an agilent eclipse c-8 column (5 µm, 250×4.6 mm) at ambient temperature. a 23 full factorial design was performed for optimization of mobile phase for separation of two dru...

recently full factorial design approach has been used to assess the recycling potential of a given waste. the objective of this study is to identify the significant factors and interactions involved in maximizing compressive strength of concrete when chromium waste is used as admixture. in this respect, experimental factors at two levels, which are admixture type (chromite/ chromite+ superplas...

One of the problems in removing pollutants from water  by photocatalytic methods is the separation of the catalyst from the solution. In this study, the catalyst stabilization method was used to solve this problem. Nano ZnFe2O4 supported on Copper Slag (CS) produced in this research is an environment-friendly, simple and cost-effective catalyst. ZnFe2O4</su...

The aim of this study is to manipulate musical cues systematically to determine the aspects of music that contribute to emotional expression, and whether these cues operate in additive or interactive fashion, and whether the cue levels can be characterized as linear or non-linear. An optimized factorial design was used with six primary musical cues (mode, tempo, dynamics, articulation, timbre, ...

1. In poultry investigations, the main interest is often to study the effects of many factors simultaneously. Two or three level factorial designs are the most commonly used for this type of investigation. However, it is often too costly to perform when number of factors increase. So a fractional factorial design, which is a subset or a fraction of a full factorial design, is an alternative. Th...

We give a combinatorial interpretation for the super Catalan number S(m,m + s) for s ≤ 3 using lattice paths and make an attempt at a combinatorial interpretation for s = 4. We also examine the integrality of some factorial ratios.
