The identification of the flux for a system of conservation laws is studied from a numerical point of view, on the specific example of chromatography. Different strategies to compute the exact gradient of the discretized optimization problem are developed and compared. Numerical evidence of the convergence of the method is also given in the scalar and binary case. Finally a ternary mixture with...

The τ-boride Ni(23-x)Bi(x)B(6) [x = 2.44 (1)] adopts a ternary variant of the cubic Cr(23)C(6)-type structure, with Ni(8) cubes and Ni(12) cubocta-hedra arranged in a NaCl-type pattern. Two of the four independent metal sites (8c, 3m symmetry; 4a, mm symmetry) are occupied by a mixture of Ni and Bi atoms in a 0.106 (6):0.894 (6) and a 0.350 (7):0.650 (7) ratio, respectively.

In the present paper the heat exchange performance of a counter flow double-tube condenser for a ternary refrigerant mixture R407C, composed ofHFC32/HFC125/HFC134a, is calculated using a prediction method developed by the present authors. The axial distributions of vapor and liquid bulk mass fraction, temperature, heat flux, mass flux, etc., are obtained for both a smooth tube and a microfin tu...

Tripartite synergistic model of solid core technology, dual organic modifiers and combined mixture design was implemented to achieve assay related substances method by reverse phasehigh performance liquid chromatography with short run time, enhanced sensitivity improved resolution between multiple impurity peaks. pH mobile phase, ternary phase composition high column temperature are experimente...

Indomethacin (IND) is one of the supporting drug candidates for colonic targeting but it belongs to BCS class II category presenting a challenge in optimal at site. To overcome this challenge, we sought prepare pH-dependent soluble ternary solid dispersion (SD) IND improved solubility and dissolution rate colon without need coating. The current study focuses on preparation binary SDs API with s...

Biocompatible oil-in-water (o/w) micro-emulsions can be prospective drug delivery vehicles for their capability to solubilize lipophilic (oil soluble) drugs in the dispersed oil. Plant oils are considered suitable for such a purpose. In this study, we have attempted to examine the dispersion of corn, cottonseed, clove, orange and peppermint oils, as well as isopropyl myristate (IPM) in water co...
