The partial and integral enthalpies of mixing of liquid ternary Ni-Sn-Zn alloys were determined. The system was investigated along two sections xNi/xSn ≈ 1:9, xNi/xSn ≈ 1:6 at 1073 K and along two sections xSn/xZn ≈ 9:1, xSn/xZn ≈ 4:1 at 873 K. The integral enthalpy of mixing at each temperature is described using the Redlich-Kister-Muggianu model for substitutional ternary solutions. In additi...

underground dams have recently been considered as hydrological structures for the development of water resources, especially in the dry regions of iran. in this investigation along with the basic studies and the aquifer flow modeling, the probable hydrogeological effects of an underground dam are investigated. the proposed place for the ganjeh underground dam is chehel-khaneh aquifer located in...
