Since the advent of theoretical materials science some 60 years ago, there has been a drive to predict and design new materials in silicio. Mathematical optimization procedures to determine phase stability can be generally applicable to complex ternary or higher-order materials systems where the phase diagrams of the binary constituents are sufficiently known. Here, we employ a simplex-optimiza...

Staphylococcus aureus is a normal bacteria flora in the oral cavity and often causes infections. Saffron (Crocus sativus L.) contains flavonoids that can inhibit growth of aureus. extract formulated into edible film preparations because it control drug release maintain active substances, especially antibacterial ones. This study aims to determine effect comparing PVA xanthan gum concentrations ...

Background: Antibacterial and antifungal activities of citronella grass extract are widely used, but there is no pleasant dosage form for patients who unable to swallow. Citronella (Cymbopogon nardus (L.) Rendle) lozenges were prepared with wet granulation method containing natural or synthetic polymer (PGA/PVP/gelatin) binders. Objective: This study aimed determine the most optimal lozenge for...

In the context of the teleparallel equivalent of general relativity, the Weitzenböck manifold is considered as the limit of a suitable sequence of discrete lattices composed of an increasing number of smaller an smaller simplices, where the interior of each simplex (Delaunay lattice) is assumed to be flat. The link lengths l between any pair of vertices serve as independent variables, so that t...

Rheological properties are very important parameters in the production of products with high-quality and desirable texture. So far, many attempts to produce low-calorie milk chocolate have not succeeded. Therefore, the present study aims to evaluate the effects of sugar substitutes on rheological characteristics of prebiotic milk chocolate using Simplex-lattice mixture design. For doing this, a...
