In this research, the properties and characteristics of Biglar refractories bauxite mines have compared with two types of industrial China's and Iranian (Doplan super) refractory grade bauxite in order to use in refractory industries. At first, physical, chemical and thermal properties, phase and microstructural characteristics have been measured and sintered samples of Biglar Bauxite at differ...

Frozen green beans (Phaseolus vulgaris, L.) thermal conductivity (k) and heat capacity (Cp) were determined experimentally by a one dimensional finite difference (transient method) and differential scanning calorimetry, respectively. Thermal properties were also estimated by the inverse problem methodology (IPM). Heat capacity and thermal conductivity behaviour with temperature were modelled by...
