stoichiometric tetragonal bal-xsrxtio3 (x = 0.23) nanopowders were prepared by stearic acid gel(sag) method using barium stearate, strontium stearate, tetrabutyl titanate as ba, sr, ti sourcesand stearic acid as complexing reagent. thermal analysis including differential thermogravimetric(dtg) and tg, fourier transform infrared spectrometry (ftir), x-ray diffraction (xrd) andtransmission electr...

Massively-parallel, distributed-memory algorithms for the Lagrangian particle hydrodynamic method (Samulyak et al., 2018) have been developed, verified, and implemented. The key component of parallel is a management module that includes construction octree databases, dynamic adaptation refinement octrees, migration between subdomains. based on p4est (parallel forest k-trees) library. massively-...

This study is aimed at investigating the excavation damage characteristics of surrounding rock in Jinping deeply buried marble tunnels, China. According to acoustic detection results tunnel cross-sections under condition boring machine (TBM) obtained on site, PFC microscopic parameters Types II/III were simulated and calibrated through PFC2D program. In doing so, deeply-buried sections diversio...

‎the problem of two-phase mhd boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. the effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. the governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...
