«The era of «steel apples» and «green robots». Smartphone addiction: a medical problem, a cultural phenomenon, or a fiction media?»

Download an article

The article is devoted to the one of acute problems of society, that is smartphone addiction, because in recent decades, «smart» devices become ingrained in everyday lives of almost every person. The sphere of interest of many scientific studies is the study of «high-tech» addictions. One of the particular forms of this type of addictive disorder is smartphone addiction. Currently, there is an expansive increase in the prevalence of smartphones on various hardware and software platforms. The authors of the article wonder whether smartphone addiction can be a form of behavioral addiction or it can be considered a part of the «problematic» use by healthy people? To solve this problem, this review examines the correlation relationship between substantive and behavioral addictions based on existing criteria for diagnosing addictive disorders, and also outlines the socio-cultural boundaries of smartphones use.

«Antimicrobial properties of the peptide substance Bacillus Subtilis PSF-19»

Download an article

The subject of the study is a strain of Bacillus subtilis PSF-19 isolated by us from vegetable raw materials (Passiflora preparation), which is capable of producing antimicrobial substance (AMV) suppressing pathogenic bacteria. The article discusses the method and conditions of extraction from the culture fluid fraction of AMV, active against Listeria monocytogenes – one of the dangerous intestinal pathogens that infect food. Using biochemical methods and mass spectroscopy, the molecular weight and the peptide nature of the active fraction of AMV were determined. A fraction of AMV with a molecular weight of 3,4–3,6 kDa has bactericidal activity, which is destroyed by treatment with proteolytic enzymes, which allowed it to be attributed to the group of low-molecular antimicrobial peptides – bacteriocins. The studies allow to consider the strain Bacillus subtilis PSF-19 as a producer of bacteriocin, especially effective against pathogens of intestinal listeriosis. The establishment of the fact of destructibility of proteolytic enzymes, finding the conditions of microbiological synthesis of AMV, its isolation and accumulation for research, provide opportunities for practical use as a means for decontamination of the environment instead of traditional antibiotics.

«Bulk properties of multidimensional objects»

Download an article

For the purpose of learning multidimensional models, difficult for perception, representations and technology (device) of the description and measurement of volume and amount of the substance filling the volume of multidimensional objects are considered. Alternative options of multidimensional set of one-dimensional models and unified multidimensional model of three-dimensional objects are compared. The technology of measurement of multidimensional volume and amount of the substance that fills volume is shown. The authors came to the conclusion when transferring from a set of coordinate vectors of material points in complete spatial angle 4π steradian to multidimensional model of in pairs orthogonal vectors, calculation of volume of a multidimensional object significantly becomes simpler. The conclusion is that potentially infinite-dimensional model of an object represents the sphere in which balk of volume, the quantity and energy of the substance filling volume are entirely concentrated on its surface.

«Revisiting the friction of high entropy alloys and coatings»

Download an article

In this paper, the authors propose a new approach to the consideration of the friction phenomenon in HEAs and, in particular, dry friction. An equation is obtained that shows the nonlinear dependence of the friction coefficient on Gibbs energy G0, on temperature T, on the concentration of the number of electrons N and which allows predicting the formation of high entropy alloys and coatings.

«Bases of sustainable development and concept of green economy in practice of oil and gas companies in the XXI century»

Download an article

The practice of implementing the key principles of sustainable development and the green economy in the activities of modern oil and gas companies is considered in the article. The authors come to conclusion that the implementation and construction of policies focused on the modernized goals and objectives of the green economy, meeting modern challenges in development, can be a direction for the development and updating of strategies of oil and gas companies in Russia in the medium term.
