Experimental study of the process of hydrogen production by methane pyrolysis in a molten tin layer

The article presents experimental studies on the methane pyrolysis process in a 30 cm layer of molten tin. The experiments were carried out on a specially made setup in the temperature range from 800 °С to 1000 °С, at a pressure of 4.5 atm, and with a gas flow rate of 3 l/h. The dependence of hydrogen concentration, methane, and its derivatives (ethane, ethylene, and acetylene) in the produced mixture of hydrocarbon gases has been obtained

Management of small agricultural cooperation and corporatization

The possibility of applying the principles of corporate governance in the practice of small agricultural businesses is considered. The authors believe that cooperative associations of small market participants can transform into corporate associations at a certain stage of development. The scientific novelty is represented by an improved economic mechanism of two-level cooperation of small agricultural enterprises with the financial participation of municipalities, regional and Federal authorities and the formation of their own cooperative Bank. The mechanism recommended by the authors is aimed at motivating small business participants to cooperate by the possibility of subsequent corporatization. The implementation of the cooperation development plan will require temporary exemption of its participants from the tax burden, while the state should practice joint construction of processing, logistics and other necessary facilities in the agricultural sector, with the subsequent transfer of its shares to consumer cooperatives of small businesses

Imbalance in estimates of the cost of the youth in the labor market of employers and job seekers as a factor of unsustainable socio-economic development

The authors’ research is devoted to the study of career expectations of young professionals entering the labor market in terms of the cost of their labor. The heads of enterprises and scientists are faced with the acute question of how to learn to understand the behavior of new actors in the labor market in order to effectively use their potential. The situation on the labor market in Russia remains unstable and variable. There is no balance between supply and demand for certain professions, in labor cost estimation, so it is difficult for a young specialist to find a job in their specialty. From the position of sustainable socio-economic development, management decisions should balance the needs of the future and the present in the labor market, which corresponds to the use of investments (investments in labor capital), in view of technological progress and ongoing institutional changes. The materials of the empirical base of the study are the results of monitoring resumes of applicants on the labor market in a number of labor-surplus and well-provided regions by gender and certain age groups, salary expectations depending on education, as well as by working conditions (salary) from employers indicated in vacancies according to the Scientific Research Center data in the field of career guidance and labor psychology

The goal setting of modern criminal proceedings subject to regulatory consolidation

The article deals with the correlation of some of the most significant categories of criminal procedure activity: “purpose”, “purpose” and “tasks”. The authors conclude that without goals and objectives, it is impossible to imagine any organized, well-coordinated and planned activities, especially those regulated by law. The goal organizes the participants in the criminal procedure activity, advises them about the result, while the tasks help them to exercise their powers. The unity of purpose and objectives, which forms the goal-setting of criminal proceedings, attaches cohesion and coherence to the actions of numerous subjects, i.e. builds a capable system. Therefore, any process, including law-making and law enforcement, can and should be characterized from the point of view of its purpose and objectives. This indicates the objective need to establish not only the purpose, but also the goal setting in the law. The attempt to concentrate the tasks of the criminal process solely on the protection of the rights and legitimate interests of the individual (Article 6 of the Code of Criminal Procedure) seems unproductive. This provision is true, but it is not sufficient, since it does not take into account the state tasks that are initially present in such branches of public law as criminal procedure law and the criminal proceedings regulated by it. The criminal process cannot fulfil its purpose without taking into account the tasks of criminal law. By implementing them, criminal law and criminal procedure protect, among other objects, the life, health, interests and freedoms of citizens, as well as public order, public security, the constitutional system of the state, peace and security of mankind

RCSED—A Value-added Reference Catalog of Spectral Energy Distributions of 800,299 Galaxies in 11 Ultraviolet, Optical, and Near-infrared Bands: Morphologies, Colors, Ionized Gas, and Stellar Population Properties

International audienceWe present RCSED, the value-added Reference Catalog of Spectral Energy Distributions of galaxies, which contains homogenized spectrophotometric data for 800,299 low- and intermediate-redshift galaxies (0.007< z< 0.6) selected from the Sloan Digital Sky Survey spectroscopic sample. Accessible from the Virtual Observatory (VO) and complemented with detailed information on galaxy properties obtained with state-of-the-art data analysis, RCSED enables direct studies of galaxy formation and evolution over the last 5 Gyr. We provide tabulated color transformations for galaxies of different morphologies and luminosities, and analytic expressions for the red sequence shape in different colors. RCSED comprises integrated k-corrected photometry in up to 11 ultraviolet, optical, and near-infrared bands published by the GALEX, SDSS, and UKIDSS wide-field imaging surveys; results of the stellar population fitting of SDSS spectra including best-fitting templates, velocity dispersions, parameterized star formation histories, and stellar metallicities computed for instantaneous starburst and exponentially declining star formation models; parametric and non-parametric emission line fluxes and profiles; and gas phase metallicities. We link RCSED to the Galaxy Zoo morphological classification and galaxy bulge disk decomposition results of Simard et al. We construct the color-magnitude, Faber-Jackson, and mass-metallicity relations; compare them with the literature; and discuss systematic errors of the galaxy properties presented in our catalog. RCSED is accessible from the project web site and via VO simple spectrum access and table access services using VO-compliant applications. We describe several examples of SQL queries to the database. Finally, we briefly discuss existing and future scientific applications of RCSED and prospective catalog extensions to higher redshifts and different wavelengths

Composition and Textural Characteristics of Char Powders Produced by Thermomechanical Processing of Sunflower Seed Husks

The paper presents the results of experimental studies on the production of fine char powder from sunflower seed husks by a novel method of thermomechanical treatment with pulsed shock waves and supersonic jets of the mixture of ultra-superheated (above 2000 °C) steam and carbon dioxide, as well as the results of examination of the produced char powder in terms of its chemical, phase, and granulometric composition and structural, morphological, and texture characteristics. The objective of the research is to explore the possibility of using the resulting char powder as a sorption-active material for organic substances. It is shown that the obtained char particles and their agglomerates have an average size of 20–30 nm and 12–24 µm, respectively, have the shape of disks and ellipsoids, consist mainly of amorphous carbon (up to 56 wt%) and oxygen (up to 42 wt%), and have a specific surface area of 1.1–1.7 m2/g. It is concluded that such a char powder can be used as an absorbent for organic substances when dried and deagglomerated
