Today there is a growing research activity in order to investigate the possibility of using various waste or alternative materials in the cement and other industries. In this paper the possibility of using wood paulownia (lat. Paulownia elongata) as a completely new type of alternative fuel has been analyzed. Its applicability in cement industry in...

Water that is commonly used for drinking is groundwater, that appears on the surface of the Earth's crust as sources of different types and capacities, and in most cases that water is chemical, physical and bacteriological acceptable and suitable for use. In some cases, there is some blurring of water, that is the result of heavy rainfall or some h...

The results of the comparative prediction of thermodynamic properties for Ga-Zn-Sn system are presented in this paper. Two thermodynamic predicting models were used for the calculation – one symmetrical (Muggianu), one assymetrical (Toop) model and general solution model. The calculations were done for different sections in exa...
