This paper investigates effects of different additives on morphology and subsequently, separation performance of asymmetric flat sheet Polyvinylidene fluoride (PVDF) membranes to separate CO2 using membrane contractor. Five different additives from different chemical families including Lithium chloride (salt), Polyethylene glycol 400 (polymer), glycerol (weak anti-solvents), methanol...

With the advancement of statistical theory and computing power, data sets are providing a greater amount of insight into the problems of today. Statisticians have an ever increasing number of tools to attack these problems, some of which can be implemented in the area of mixture modeling. There is a great deal of literature on mixture models and this work attempts to provide a general overview ...

desirability and good background of yogurt have led the manufacturers to use this product mostly for producing milk-based probiotic products. the aim of this study was to evalutate the effect of a mixture of prebiotics including oligofructose, lactulose, and inulin on physicochemical properties (ph value, acidity, and syneresis) of synbiotic yogurt containing lactobacillus casei. pasteurized mi...

Mixture experiments involve the mixing or blending of two or more ingredients to form an end product. Typically, the quality of the end product is a function of the relative proportions of the ingredients and other extraneous process factors such as heat or time. When some of the process variables are either uncontrollable or difficult to control (i.e., noise variables) the goal of a mixture ex...

nitration of potassium sulphamate was carried out using a mixture of sulphuric and nitric acid at -30 °c. the reaction time was optimized at the mole ratio of sulphuric to nitric acid of (1:3.5). the difference in product yield by changing the potassium to ammonium sulphamate was studied throughly. it was found that both the yield and purity of the product is better starting with potassium sulp...

impact of supply chain drivers on supply chain performance has no far been studied. in this research we want identifying supply chain drivers, classifying them and examining their relationship with iran's supply chain performance. this research has innovation in identifying and classifying drivers and examining relationship between drivers and supply chain performance we used bsc for assessing ...

We compare two probabilistic approaches to neural networks the first one based on the mixtures of product components and the second one using the mixtures of dependence-tree distributions. The product mixture models can be efficiently estimated from data by means of EM algorithm and have some practically important properties. However, in some cases the simplicity of product components could app...
