This study was conducted to determine the role of thermal treatment on crystallinity and pore characteristics porous ceramic, which prepared from natural clay (NC) chitosan (CS) biopolymer using gel casting method. CS used as an environmentally friendly pore-forming agent. The applied temperature based analysis (TGA/DTA) results followed a sintering 900 1100 °C. showed that at temperatures 1000 °C, crystallinities ceramic decrease (from 76.06 74.06%) crystallite size decreases 35.71 34.47...

Abstract In constructing three-dimensional models, photogrammetry techniques, particularly close-range are growing and becoming an alternative, specifically for architectural historical site modeling. Because they less costly, simpler, quicker to complete while producing positive results, there is a great number of software. Still, it difficult determine which application provides the best measurement results because user expectations vary. It necessary conduct geometric precision...
