Introduction: In the first part of this talk, we present an algorithm for the numerical treatment of twopressure, two velocity continuum models for heterogeneous, immiscible mixtures [1]. This algorithm has been employed in a numerical study of unsteady shear flows of fluid-saturated granular materials, as predicted by the continuum model of [2]. A representative sample of these results are pre...

We study a free interface problem of finding the optimal energy configuration for mixtures of two conducting materials with an additional perimeter penalization of the interface. We employ the regularity theory of linear elliptic equations to give a short proof of a partial regularity proved by Fan Hua Lin in [8], and to study the possible shapes of conical sets which are critical points.

This study evaluates the short-term resilient behaviour of cold in-place recycled (CIR) asphalt mixtures with bitumen emulsion when they are more similar to non-cohesive granular materials than conventional hot mixtures. Gyratory compacted CIR specimens were manufactured using different proportions bituminous and water, dynamic triaxial tests conducted at curing times. The moduli obtained exper...

In this study, mechanochemcical process(MCP) is applied to synthesize ultrafine TaC powders. In this research, nano powder composite TaC-TaB2 was produced using mixtures of tantalum carbide and boron carbide as raw materials via mechanochemical process. The phase formation characterization during process was utilized by X-ray diffractometry (XRD). The morphology of synthesized powder was studie...

Objective(s) The purpose of the present study was to use the solid dispersion (SD) technique to improve the dissolution rates of indomethacin (IMC). Materials and Methods IMC solid dispersions in PVP K30 and isomalt (GALEN IQ 990) were prepared using the solvent evaporation technique and a hot melt method in weight ratios of 2, 10 and 30% (IMC:PVP). Solid dispersions and physical mixtures we...
