The use of computational fluid dynamics in continuous operation industries have become more prominent recent times. Proposed system improvements through geometric changes or control strategies can be evaluated within a relatively shorter timeframe. Applications for discrete element methods (DEMs) real life simulations, however, require validated material-calibration-methods. In this paper, the ...

Extracellular matrix (ECM) components, such as chondroitin sulfate (CS) and tricalcium phosphate, serve as raw materials, and thus spatial patterning of these raw materials may be leveraged to mimic the smooth transition of physical, chemical, and mechanical properties at the bone-cartilage interface. We hypothesized that encapsulation of opposing gradients of these raw materials in high molecu...

identification, authentication and quality control are essential to ensure safety, therapeutic potency, efficacy and reproducible quality of herbal medicines. the aim of this study is to use taxonomic method for authentication of traditional herbal drugs which are commonly sold in herbal shops in iran. in this regard, twenty-seven cases of herbal drugs suspected to be adulterated were investiga...

M. Dudek, AGH University of Science and Technology, Krakow, Faculty of Management, Poland In the blast-furnace production, raw materials may account for approx. 50 % of the pig-iron manufacture costs. Therefore, any, even small, saving in the sphere of raw material purchasing will translate into the reduction in the cost of the pig-iron manufacture. The selection of appropriate supply sources a...
