Title: The role of order and disorder in thermal and material sciences, Part 1. Heat and society Abstract The notion of heat is thoroughly analyzed and its historical links are searched particularly with relation to both the Greek philosophy (Milesians, Pythagoreans, atomists, etc.) and in the present day thermal physics... |

Title: Activity measurement of solid Cu-In alloys by EMF method with solid electrolyte Abstract The thermodynamic activity of indium in the solid Cu-In alloys was obtained from the emf measurement of cell: In,In2O3|ZrO2(+11mol%CaO)|Cu-In,In2O3 for 16 alloys in the temperature range 773 to 900K. Activity changes with... |

Title: The influence of the rate of selenium crystallization from aqueous solutions on its morphology Abstract Selenium crystallization process from aqueous solutions was investigated at constant temperature of 357 K. Two different reducers were used, namely dissolved NaHSO3 and gaseous SO2. Experiments were conducted for solutions with... |

Title: Modelling of mulite solid-solutions in the system Al2O3-SiO2 Abstract A model for the mullite formation from kaolinites and the solid-solution range of mullite in the Al2O3-SiO2 system has been evaluated. This rather complicated model implies that both octahedral and tetrahedral coordinated Al3+ -ions as well as... |

Title: The efect of room tempearture pre-ageing on tensile and electrical properties of thermomechanicaly treated Al-Mg-Si alloy Abstract A commercial Al - 0.62%Mg – 0.57%Si was thermomecanically treated (TMT). The TMT process included solution treatment, room temperature preageing, drawing (e=95%) and final ageing. The experimental data were proceeded... |

Title: DTA and TGA study of MeSO4 (Me=Fe,Co,Ni) dissociation in the presence of coke Abstract MeSO4 (Me = Fe, Co, Ni) dissociation is investigated in order to estimate the effect of temperature, time and presence of coke as reducer on the degree and mechanism of dissociation. It is proved that the presence of... |
