The Middle–Lower Yangtze River Metallogenic Belt is an important copper and iron polymetallic metallogenic belt in China. Today’s economic development inseparable from the support of metal mineral resources. With continuous exploitation shallow easily identifiable mines China, prospecting work deep hidden very important. Mineral prospectivity modeling (MPM) means to improve efficiency explorati...

As part of the European-Peruvian ION4RAW project (Horizon 2020 framework programme European Commission), which aims at developing mineral-processing technology to recover selected by-products (e.g., Te, Bi, Co, Re, Mo, Pt, Sb, Ge, Se, In) from primary Cu-Ag-Au deposits, we assessed a geographical inventory elements. However, not all elements economic interest today have been systematically assa...

The new epoch of the 21th century develops new globally interrelated and interacting high-tech and cyberspace based civilizations and rapid transitions and other interactions between old and new models of life, orientation and behavior. Bio-logy and socio-logy describe bios as interrelated interactions of living beings and biotopes, natural, cultural, technical. The concept of bio-ethics in the...

The paper describes a new dynamic protocol for managing replicated data. Like the existing dynamic schemes, our protocol involves reconfiguring the system dynamically to reflect failures and repairs as they occur, so that the data may be kept available for user operations even if only one replica of the data remains accessible. However, in the existing schemes, it is required for the correctnes...

We investigate the dependence of the epoch of reionization on the properties of cosmological perturbations, in the context of cosmologies permitted by WMAP. We compute the redshift of reionization using a simple model based on the Press–Schechter approximation. For a power-law initial spectrum we estimate that reionization is likely to occur at a redshift zreion = 17+10 −7 , consistent with the...
