Environmentally Friendly Pyrometallurgical Scheme for Vacuum Separation of Non-Ferrous Metals from Waste Products in Incineration Plants

Residues from the municipal solid waste processed in incineration plants in European countries are an important raw material to obtain valuable components, including non-ferrous metals. State and private companies specializing in the processing of waste incineration slag as products most often receive concentrates of non-ferrous metals, which, on average, contain, in mass. %: 20÷60 Cu; 10÷30 Zn; 5÷15 Pb; ~ 1 Al; ~ 1 Sn; ~ 1 Fe, up to 50 g/t Аu and up to 3,000 g/t Ag. Concentrates are sent for processing to smelters without taking the cost of zinc into account. The paper presents the study on the separation of metallic zinc into a separate product (zinc concentrate) from the collective concentrate of non-ferrous metals by a vacuum-thermal method, the safest from the environmental point of view. The study was performed with non-ferrous metal concentrate of +0.3-0.8 mm in size, containing wt. %: 68.07 - Cu; 12.4 - Zn; 14.78 - Pb; 0.99 - Al; 1.2 - Sn; 0.15 - Fe, up to 2.0 kg/t - Ag. The material was heat treated at 800÷900℃ with the residual pressure in the system of less than 0.13 kPa. Zinc concentrate was obtained, containing more than 96% of the main component. At the same time, the Cu content increased by 14.09% in the residue from the heat-vacuum treatment. Other metals (Pb, Al, Sn) including noble metals were also concentrated in the residue. The results of the study show that it is possible to separate zinc into a separate product from non-ferrous metal concentrates containing more than 10% Zn in the initial material by the proposed method.

Development and Conformity Assessment of ECG-Photometric Complex Software

Introduction. The article is devoted to the software "PulseWave", which is used as part of the ECG-photometric complex for research in medical institutions. For further implementation of the complex in medical practice, it is necessary to assess the compliance of this software in accordance with the requirements of the technical regulations for medical devices. There are two ways to perform software conformity assessment: as part of the ECG photometric complex or separately from it (stand alone). In this paper, the option of conducting a stand alone conformity assessment was chosen, i.e. as a separate product. This approach is the most promising, given the development of "cloud" storage and data processing environments and the need to introduce into medical practice of treatment and prevention facilities in Ukraine. The purpose of the article is to develop software and prepare it for conformity assessment in accordance with the requirements of the technical regulations for medical devices. Results. The authors consider the structure and principle of operation of the software "PulseWave" ECG-photometric complex. The main stages of the life cycle of this software according to international standards are given. A risk assessment report has been developed, which shows and evaluates the main errors that may occur in the work of the software; and ways to eliminate them. Conclusions. The software development, development of its life cycle and risk analysis provide an opportunity to start the procedure of assessing its compliance with the requirements of the technical regulations for medical devices in accordance with international standards. Keywords: software, conformity assessment, life cycle, application risks.

A gridded surface current product for the Gulf of Mexico from consolidated drifter measurements

A large set of historical surface drifter data from the Gulf of Mexico – 3770 trajectories spanning 28 years and more than a dozen data sources – are collected, uniformly processed and quality controlled, and assimilated into a spatially and temporally gridded dataset called GulfFlow. This dataset is available in two versions, with 1/4∘ or 1/12∘ spatial resolution respectively, both of which have overlapping monthly temporal bins with semimonthly spacing and which extend from the years 1992 through 2020. Together these form a significant resource for studying the circulation and variability in this important region. The uniformly processed historical drifter data from all publicly available sources, interpolated to hourly resolution, are also distributed in a separate product called GulfDriftersOpen. Forming a mean surface current map by directly bin-averaging the hourly drifter data is found to lead to severe artifacts, a consequence of the extremely inhomogeneous temporal distribution of the drifters. Averaging instead the already monthly-averaged data in GulfFlow avoids these problems, resulting in the highest-resolution map of the mean Gulf of Mexico surface currents yet produced. The consolidated drifter dataset is freely available at https://doi.org/10.5281/zenodo.3985916 (Lilly and Pérez-Brunius, 2021a), while the gridded products are available for noncommercial use only (for reasons discussed herein) at https://doi.org/10.5281/zenodo.3978793 (Lilly and Pérez-Brunius, 2021b).

Fintech Development: The Trends and Consequences for the Financial Services Market

The article is aimed at determining the consequences of digitalization and development of the fintech sector for the financial services market. According to the results of the analysis, a number of transformational trends for the financial services market are identified and characterized, among which the major ones: disintermediation in the financial services market – as a process of «cutting out» the classical financial institutions from the direct process of financial asset exchange; democratization of financial services processes – as a process of expanding the range of financial products; disaggregation of financial services – as a process of splitting financial services into separate financial products; increasing the inclusiveness of financial services, which provides better availability for different categories of customers; emergence of decentralized finances – as a concept and ecosystem of financial services, in which the provision of financial services and products is carried out directly without traditional financial intermediaries within the public open and decentralized blockchain network; development of automation and virtualization of financial services, which involves the widespread use of artificial intelligence technologies, algorithmic assessment of customer creditworthiness, autonomous risk management, automated trading on the exchange, the work of virtual assistants, robo-advisers and security systems against fraud; appearance of built-in financial products as part of services outside of the applications of financial institutions. The consequence of these trends is a reduction in the demand for financial services as a separate product of classical financial institutions; reducing the profits of traditional financial service providers; expansion of new business models of financial services provision in cooperation with technology companies; increasing the need to update the regulatory support of financial services processes, as well as the integration of mass financial products into the client offers of non-financial companies within a single ecosystem of products and services of a digital company.

FACTORS OF FORMATION AND DEVELOPMENT TRENDS OF THE LOCAL RUSSIAN MARKET OF ELECTRICAL PRODUCTS

The purpose of the research is to systematize the factors of formation of one of the directions of the market of industrial goods, namely, the market of electrical goods. Many works by both domestic and foreign authors, who present different points of view and approaches to the study of this phenomenon, are devoted to the functioning of local markets. The market of industrial goods and its component — the market of electrical goods-occupies its place among the local markets of the Russian Federation. Exterial and internal factors of this market formation are considered, and dominant factors are highlighted. External, uncontrolled factors have a significant impact on the formation and implementation of the strategy of enterprises participating in the local market. Internal, controlled factors, in turn, are divided into stable and changing. Internal factors allow local market participants to respond to external factors in a timely and adequate manner and minimize their negative impact. The current state of the Russian local market of electrical goods is characterized by the import dependence of some Russian manufacturers of electrical goods on separate product groups. The market is also characterized by growth, which is due to the strategic importance of this product for other sectors of the economy. Modern trends in the development of the market of electrical goods are identified and analyzed, including the analysis of the structure and volume of production of electrical products in the context of domestic production and import revenues for selected groups of goods. The structure and dynamics of export deliveries of electrical goods are also analyzed in the context of the selected groups of goods and recipient countries. Keywords: local market, electrical goods, demand, supply, import, export.

THEORETICAL AND METHODOLOGICAL ASPECTS OF UNDERSTANDING OF THE SYSTEM OBJECT IN DESIGN

The article is devoted to the analysis of the system object from the point of view of design from design, sociocultural and philosophical positions. The authors systematize the definitions of a system object of design proposed in the 1960–1980s by theorists and practitioners, art historians, cultural experts and philosophers from different countries, including Russia, which allows a comprehensive understanding of the phenomenon of design culture. This article is devoted to the characteristic properties of the system object in design. They were considered and analyzed on the example of the «Absheron» design-program when designing of agricultural village). This concept was developed at the All-Union Scientific Research Institute of Technical Aesthetics (VNIITE) in 1983. Using the same example, the features of the approach to designing a system object in design was observed not only as a separate product, but as a sociocultural situation that constantly changes at each design stage.
