into single-walled (SWCNTs) and multi-walled (MWCNTs) carbon nanotubes. A typical thermal conductivity change in oil based nanofluids containing carbon nanotube is portrayed by CHOI et al [1]. XUE [2] proposed a model in light of Maxwell speculation for transport properties of CNTs-based composites. Heat transfer of liquid suspensions of multi-walled carbon nanotubes is analyzed by DING et al [3......
of calcium lignosulfonate. Under optimal conditions, the leaching rates of Cu, Ni and Fe are 87.6%, 87.6% and 90.3%, respectively. The grade of PGMs enriched in the flotation concentrate is 420 g/t... to over 2000 g/t PGMs, can be used as metallurgy materials directly. For low-grade platinum group concentrates, PGMs are usually recovered as byproducts of other metals such as Cu or Ni. Currently......

the permanent displacement of the slope during the earthquake. Furthermore, using dynamic analyses based on the finite-element (FE) or finite-difference (FD) numerical methods [7, 8] can obtain the stress... displacement of slope based on Newmark method bridges the gap between the simplified pseudo- static method and complicated stress-deformation analysis. The Newmark method simplifies the failure of slopes......
