Shrinkage simplex-centroid designs for a quadratic mixture model
A simplex-centroid design for q mixture components comprises of all possible subsets of the q components, present in equal proportions. The design does not contain full mixture blends except the overall centroid. In real-life situations, all mixture blends comprise of at least a minimum proportion of each component. Here, we introduce simplex-centroid designs which contain complete blend...
متن کاملOptimization of Carboxymethyl-Xyloglucan-Based Tramadol Matrix Tablets Using Simplex Centroid Mixture Design
The aim was to determine the release-modifying effect of carboxymethyl xyloglucan for oral drug delivery. Sustained release matrix tablets of tramadol HCl were prepared by wet granulation method using carboxymethyl xyloglucan as matrix forming polymer. HPMC K100M was used in a small amount to control the burst effect which is most commonly seen with natural hydrophilic polymers. A simplex centr...
متن کاملApplication of simplex-centroid mixture design to optimize stabilizer combinations for ice cream manufacture.
This study aimed to obtain the optimum formulation for stabilizers in ice cream that could contest with blends presented nowadays. Thus, different mixtures of three stabilizers, i.e. basil seed gum, carboxymethyl cellulose, and guar gum, at two concentrations (0.15 % & 0.35 %) were studied using mixture design methodology. The influence of these mixtures on some properties of ice cream and the ...
متن کاملTraditional and Alternative Technologies for Arsenic Removal from Drinking Waters
Arsenic contamination in drinking waters has been a serious public health concern due to both carcinogenic and other health effects. The main sources of human exposure to arsenic are the drinking waters. Arsenic can cause chronic illness and death, even at low levels of arsenic concentration in drinking waters. There are many technologies available for removal of arsenic from contaminated drink...
متن کاملarsenic removal from synthetic water using activated carbon derived from walnut shell
increasing of fresh water consumption and consecutively drought periods caused reduction of renewable freshwater resources in recent years. one of the basic strategies to conquer this problem is using non-conventional water resources particularly reuse of polluted water. in this study, activated carbon derived from walnut shell was used as tertiary treatment. activated carbon powder was used in...
