Objective: Hot Melt Extrusion (HME) is one of the techniques for preparing a solid dispersion hydrophilic excipient known as no solvents practical method to increase solubility drugs. Apigenin (APG) has properties that thermal stable with melting point 345-350 °C but very low in water around 1,35 µg/ml. The polymer HME are Soluplus and Kollidon VA 64. study aims optimize kind formulae improve d...

hot spots are among the most serious operational issues in furnaces as they may result in the destruction of tubes. hence, it is essential to locate such hot spots precisely on the tube surfaces inside the industrial furnaces in order to secure a safe design and operation. in the current study, we have extended the model proposed by talmor in order to precisely locate the combustion hot spots o...

The work is devoted to a review of works published in recent years on the development chemical structure soluble and hot-melt copolyimides, including brief description their synthesis properties.

Various causes for mantle melting (decompression, heating or release of water) combined with current estimates of upper mantle temperatures and the state of stress in the lithosphere suggest that in many regions the asthenosphere might be partially molten, but melts may not always be able to rise to the surface. The governing equations describing melting, melt segregation, compaction and deplet...
