Economic tools for realization of methane production project on Kuzbass coal deposits
Environmental issues and, above all, issues related to the release of greenhouse gases into the atmosphere, such as coal bed methane, actualize the challenge of searching a variety of options for its disposal. The difference in the macroeconomic, industrial, geological and infrastructural features determine the need to choose the most cost-effective option for using of methane emitted from the coal deposits. Various economic ways to improve the profitability of production are viewed on the basis of the analysis of methane production project from Kuzbass coal deposits, Kemerovo region, Russia
Quantum-chemical study of electronically excited states of protolytic forms of vanillic acid
The paper describes an analysis of possible ways of deactivation of electronically excited states of 4-hydroxy- 3-methoxy-benzoic acid (vanillic acid) and its protolytic forms with the use of quantum-chemical methods INDO/S (intermediate neglect of differential overlap with a spectroscopic parameterization) and MEP (molecular electrostatic potential). The ratio of radiative and non-radiative deactivation channels of the electronic excitation energy is established. The rate constants of photophysical processes (internal and intercombination conversions) occurring after the absorption of light in these forms are evaluated.

The Model of Bioethics as "Semiotic Attractors" for Diagnosing Innovative Strategies of Training Specialists for NBICS-Technologies Niche
Authors interpret bioethicsβ models as a fixation of the new symbolism in which sociocultural systems expressed its response to impact of technologies standardizing the image of a human being. At the moment it is NBICS technologies that are responsible for this impact. Convergency of these technologiesβ goals makes education responsible for adjustments of the future states of culture formed by NBICS-technologies. The possibility of this adjustment provided by the fact that training of specialists for the NBICS-technologies niche as the primary resource of those technologies is processed in the space of educational systems. The article reveals the structure of this space; bioethicsβ models are distributed in the context of this structure and proofs produced for understanding the semiotic essence of the phenomenon of education. These conceptual suggestions shape the original method of semiotic diagnostics of innovative educational strategies based on interpretation of bioethicsβ symbolism as "semiotic attractors" of knowledge management related to convergent technologies
The analysis of toxic connections content in water by spectral methods
The current state of ecology means the strict observance of measures for the utilization of household and industrial wastes that is connected with very essential expenses of means and time. Thanks to spectroscopic devices usage the spectral methods allow to carry out the express quantitative and qualitative analysis in a workplace and field conditions. In a work the application of spectral methods by studying the degradation of toxic organic compounds after preliminary radiation of various sources is shown. Experimental data of optical density of water at various influences are given
