Acquisition, storage and dissemination of socially dangerous information : theoretical and methodological issues of the legal prohibition

The research project is focused on the Russian and foreign practice of the legal prohibition of acquisition, storage and dissemination of socially dangerous information on the Internet. Other objects of studies include legal restrictions on freedom of the media in order to protect the constitutional order, the interests of the citizens and the security of the state.peer-reviewe

New findings of Stephanorhinus kirchbergensis in Siberia

New findings of Stephanorhinus kirchbergensis (Jäger, 1839) remains, obtained from the Asian part of Russia, are described. The material includes 39 specimens from 13 localities in West Siberia and East Siberia. It considerably expands the geographic distribution of this species of rhinoceros. A series of 11 mandibles from Siberia, including one juvenile individual with deciduous teeth, is described for the first time. We also present a large set of data on well-preserved postcranial remains. The morphology and sizes of mandibles, teeth, and postcranial remains of adult individuals of S. kirchbergensis from Siberia are similar to individuals of this species described from European localities. A series of upper teeth was subjected to mesowear analysis to assess the diet of S. kirchbergensis from West Siberia. The chemical composition (including stable isotopes) of the Siberian Stephanorhinus teeth is analyzed for the first time. Comparisons of Siberian S. kirchbergensis with European S. kirchbergensis and West Siberian Coelodonta antiquitatis broaden our understanding of the ecology, variability, and evolution of S. kirchbergensis under climatic changes in continental settings from the Middle to the Late Pleistocene. Despite small samples, we can suppose that S. kirchbergensis was widely distributed in Siberia

Wrong bonds in sputtered amorphous Ge2Sb2Te5Ge_2Sb_2Te_5

The structure of sputtered amorphous Ge(2)Sb(2)Te(5) was investigated by high energy x-ray diffraction, neutron diffraction and Ge-, Sb- and Te K-edge EXAFS measurements. The five datasets were modelled simultaneously in the framework of the reverse Monte Carlo simulation technique. It was found that apart from Te-Sb and Te-Ge bonds existing in the crystalline phases, Ge-Ge and Sb-Ge bonding is also significant in sputtered amorphous Ge(2)Sb(2)Te(5). According to our results, all components obey the '8-N' rule
