Realization of the set purpose involves the consistent solving of such tasks: by referring to the research literature, to outline the forms of transition to modern methodology; to explicate the main reasons for philosophy anthropologization by DesCartes; to analyze the role of art as the main form of expressing Descarte' worldview in the early writings; theoretical basis.
Abstract: Purpose of this work is to find the key to understanding the paradox of Descartes’ way of philosophizing during the recourse to the text of "early writings". Realization of the set purpose involves the consistent solving of such tasks: by referring to the research literature, to outline the forms of transition to modern methodology; to explicate the main reasons for philosophy anthropologization by Descartes; to analyze the role of art as the main form of expressing Descartes’ worldview in the "early writings". Theoretical basis. Studies by Descartes experts and the phenomenological tradition. Originality . The analysis of the "early writings" allows to determine the origins of the main doctrine of Descartes’ philosophizing. Its role is manifested in the course of clarifying the main motives of the anthropological approach of the French philosopher. That entails their rootedness in the Copernican-based scientific revolution of the New Age. A prerequisite for the authentic comprehension of the radical change carried out by Descartes is the attention to the paradigmatic significance of art, which is most fully asserted in the "early writings". It is substantiated that the appeal of young Descartes to the experience of art influences his understanding of science, as well as the awareness of human presence in the development of the scientific picture of the world and the distinction of the main components of human nature – mind and will. Conclusions . During the analysis of the contemporary literature devoted to Descartes, there is outlined the tendency to go beyond the notions of naivety and simplicity of his position, one of the manifestations of which is the increased attention to anthropology. The main motives for its actualization are rooted in the scientific revolution of the New Age, which are the form of completion of the radical worldview change initiated by Copernicus. It is about the vision of man as the main component of the universe, attention thereto in the search for the source point and the decisive authority for the world development, reflection of the thinker’s desire to build his own ethical doctrine based on human nature. While comprehending the "early wri-tings", the author focuses on the interpretation by young Descartes of art as a form of expression of truth, which enables the authentic comprehension of human nature. These ideas became the basis for the further work of the thinker, and today they open up new perspectives of exploring the anthropological foundation for later works.

TL;DR: In this paper, the authors examine the issues of multidisciplinary interaction in new scientific fields, which involve a wide variety of convergences no matter how strange at first glance they may seem, and conclude that new areas of neuroeconomics such as behavioral economics, behavioral finance, emotional economics, psychological economics, have become areas of economic theory that take into account the psychological characteristics of human perception and behavior in the process of economic activity.
Abstract: Introduction. The article is devoted to the issues of multidisciplinary interaction in new scientific fields, which involve a wide variety of convergences, no matter how strange at first glance they may seem. One of these phenomena is the interaction of psycholinguistics and neuroeconomics. The goal. The article examines the transition of modern science to multidisciplinary discourse, which makes it necessary to conceptualize and possibly operationalize methods of psycholinguistics. The conceptualization of new areas of neuroeconomics, in a psycholinguistic context, presupposes a certain mental experience that includes, in addition to the processes of creating new concepts and contextual economic knowledge, also defining the role of interests, intentions, emotions in human economic activity. Methods. Multivariate analysis, comparative analysis, extrapolation. Results. It is proved that in recent decades the development of new areas of economic science, namely those related to the development of neuroeconomics, has significantly expanded the field of psycholinguistics. The production of new paradigms of economic theory, the formation of the corresponding definitions, objects requires the design and definition of them both in form and in content. It considers the need for a theoretical and orderly definition of the functional meaning of the psycholinguistic context of new definitions, the result of which can be a conceptual system for communication between specialists in various fields of science at the level of their professional understanding. It seems that the central issues in the psycholinguistic discourse of neuroeconomics have become the relationship between economics, psychology, linguistics and psycholinguistics. Such connection is undoubtedly of a multidisciplinary nature, which contributes to the deepening of the relationship between scientific thought, culture and language and became the impetus for understanding the nature of human cognition at a higher, multidisciplinary level of development of science. This is a necessary component for understanding the meanings and structure of concepts, terms and definitions, as well as communications at a higher scientific level. Conclusions. It is concluded that new areas of neuroeconomics such as behavioral economics, behavioral finance, emotional economics, psychological economics, have become areas of economic theory that, explicitly or implicitly, take into account the psychological characteristics of human perception and behavior in the process of economic activity. These definitions catalyze the theoretical integration of various scientific fields, and, above all, psycholinguistic science.

TL;DR: In this article, a numerical model has been developed for the computer calculation of the biological wastewater treatment process in aerotanks, taking into account hydrodynamics, based on two-level mass conservation equations for the substrate and activated sludge and the velocity potential equation.
Abstract: Purpose. Efficiency determination of the aeration tank at the stage of design or reconstruction of bioreactors in which biological wastewater treatment is carried out requires the use of special mathematical models and calculation methods. The main purpose of the article is to develop CFD models for evaluating the operation efficiency of aeration tanks. Methodology. A numerical model has been developed for the computer calculation of the biological wastewater treatment process in aerotanks, taking into account hydrodynamics. The model is based on two-level mass conservation equations for the substrate and activated sludge and the velocity potential equation. The process of biological transformation of the substrate is calculated based on the Monod model. For the numerical integration of the mass transfer equations of activated sludge and substrate, the alternating-triangular difference splitting scheme is used. In this case, the basic equations are divided into two equations of a more simplified form. For the numerical integration of the equations for the velocity potential, it is split into two one-dimensional equations. Further, each equation is solved according to explicit scheme. For the numerical integration of equations that describe the process of substrate transformation based on the Monod model, the Euler method is used. Findings. The software implementation of the constructed numerical model has been carried out. The results of a computational experiment on the study of the wastewater treatment process in an aeration tank with plates are presented. This leads to the conclusion that the quality control of wastewater treatment in aeration tanks is possible with the help of plates. Originality. A multivariate CFD model has been developed, which makes it possible to quickly assess the efficiency of the aeration tank. A feature of the model is the ability to evaluate the operation of the aeration tank, taking into account its geometric shape and location of additional plates in the construction. Practical value. The constructed numerical model can be used during calculations in the case of designing aeration tanks, or in determining the efficiency of wastewater treatment under new operating conditions.

TL;DR: In this paper, the authors defined the technical limits of railway track (under reliability status) for the formation the regulatory framework for reliability and functional safety of the railway track in Ukraine.
Abstract: Purpose. The purpose of this research is to substantiate the technical limits of the railway track (under reliability status) for the formation the regulatory framework for reliability and functional safety of the railway track in Ukraine. Methodology. In order to achieve the goal of research analysis methods of the technical states of elements and trackforms that are typical of operation conditions of the railways in Ukraine were used. Findings . Technical states accordance of elements and trackforms to reliability status under existing regulations was defined. These conditions are based on the track assessments in accordance with the dimensional tape results. The status of each element of the track design affects its deformation work, but the rules are still absent that would connect state of track elements with the state of the track by estimation of the dimensional tape. The reasons on which the limits are not set were established. It was found out which researches are necessary to conduct for their installation. Originality. The classification of the reliability state of a railway track for permitted deviation at the track laying and maintenance was developed. The regulation importance the technical states of ballast section and subgrade for the developed classification was established. Practical value . Ukrzaliznytsia (UZ) is a founding member of the Council for Railway Transport of the Commonwealth. This body issued interstate standard State Standard 32192-2013 «Reliability of railway equipment. Basic concepts, terms and definitions». On this basis developed a new interstate standard «Security functional of railway equipment. Terms and definitions». At the same time UZ is a member of the cooperation of railways in International Union of Railway Transport where rules with reliable and safe operation of railways are established in all transport branches. This study will help implement these standards on the railways of Ukraine, improve the efficiency of the information in this sphere, providing mutual understanding and unity of presentation and perception of information, including contractual legal relations of economic agents with public authorities in international scientific and technical, trade and economic relations.
