active carbons were produced from bagasse, millet and sorghum straws by chemical activation with h3po4. carbon precursors with particle size of 1180 î¼m were used, in order to overcome difficulties caused by low density and high ash content. the influence of preparation conditions (temperature, residence time, and acid impregnation ratio) on the yield of the active carbons was examined. the imp...

a simple and reliable method for quick estimation of the dielectric constant of a binary solvent mixture is proposed. the validity of the proposed method has been tested for a broad range of binary solvent mixtures

This paper studies the application of principal component analysis, multiple polynomial regression, and artificial neural network ANN techniques to the quantitative analysis of binary mixture of dye solution. The binary mixtures of three textile dyes including blue, red and yellow colors were analyzed by PCA-Multiple polynomial Regression and PCA-Artificial Neural network PCA-ANN methods. The o...

the thermal diffusion factor, at, for a binary gas mixture is calculated on the basis of nonequilibrium thermodynamics. a new formula for at is derived and this factor is given for several paris of gases according to this formula.
