The Influence of Chemical Short Range Order on Atomic Diffusion in Al-Ni Melts

We use inelastic neutron scattering and molecular dynamics (MD) simulation to investigate the chemical short range order (CSRO), visible through prepeaks in the structure factors, and its relation to self diffusion in Al-Ni melts. As a function of composition at 1795K Ni self diffusion coefficients from experiment and simulation exhibit a non-linear dependence with a pronounced increase on the Al-rich side. This comes along with a change in CSRO with increasing Al content that is related to a more dense packing of the atoms in Ni-rich Al-Ni systems.Comment: 11 pages, 4 figure

Medical genetic study of population in rural districts of Buryatia Republic

Medical-genetic study of the population of 5 rural districts of Buryatia Republic has been performed. The number of investigative population was 114,6 thousands people. The 23, 9 and 8 nosological forms of autosomal dominant, autosomal recessive and Xlinked diseases were revealed, respectively. The hereditary pathology spectrum and the features of prevalence in the studied population were described
