The work is devoted to the structural characterization of carbon nanotubes by means of electronic combination scattering of light. Samples of double-walled carbon nanotubes with various electronic configurations of the layers have been synthesized, their study has been performed by means of high-resolution transmission electron microscopy, electron diffraction, Rayleigh spectroscopy, as well as spectroscopy of combination scattering of light. The structural characterization of the synthesized nanotubes has been carried out using electronic combination scattering of light, which can play the role of an additional criteria for nanotubes indexing, helping to clarify and verify the obtained results.

The work investigated the behavior of volumetric electrical conductivity (and its components) of various biological liquid media in order to determine the possibility of influencing the processes of life. In the frequency range 0-50 GHz, the following biological liquid media were studied: cold-pressed sunflower oil; sunflower oil obtained using heat treatment; fresh egg yolk and protein; Bacillus amyloliquifaciens bacteria; bacteria Escherichia coli MG1655 pXen-lux. The presence of fluctuations in the dielectric permittivity parameters, the unevenness of the frequency characteristics, in the range of 35-37 GHz, the “bursts” of values ​​characteristic of the resonance nature of this dependence were observed on the frequency characteristics of the loss angle tangents.

To date, the socio-economic situation in the country creates for the population quite significant obstacles in the implementation of tasks for the purchase of housing and other real estate through mortgage lending. However, when it comes to collecting the amounts owed on the loan, banks are faced with an analysis of the prospects for the sale of mortgaged property, as a result of which, in most cases, come to the conclusion that the original sale price of the mortgaged property with the realities of the market. In the article, the authors consider the judicial practice of determining the initial price of the mortgaged property and analyze the situation in which there is a need for judicial value examination, as well as give the main aspects of the methodology of this type of expertise. The purpose of the article is to form a clear idea of the reader about the process of resolving the dispute arising from the breach of obligations under the loan agreement.

An algorithm for determining the lower confidence limit (NDH) for the minimum value of the hardness of a set of machine parts by calculation is developed. For processing of statistical data of the hardness measurements used a three-parameter Weibull distribution is offered. The transition from sample data to population data is carried out by the graphical method. According to the algorithm, NDH was found for the minimum hardness value with confidence probabilities p=0.9; 0.92;0.93;0.94.

This article analyzes strategies to overcome the risks of a breakdown in the life of a young family. Based on the results of an empirical study conducted in the Rostov region, the authors of the article identify micro- and macro-strategies for overcoming the risks of destroying the life world of a young family within the framework of cognitive, value, and behavioral levels. The authors conclude that an important role in overcoming cognitive-value risks is given to microsocial strategies, where the family occupies key positions. Macro-social strategies are represented by the work of social institutions such as the state, the media, and education. According to the authors, the symbiosis of the selected strategies is the most effective for reducing the risks of the collapse of the life world of a young family.

The mining industry, as well as the socio-economic development of this sector, makes a significant contribution to the development of the economy of some low-and middle-income countries rich in non-fuel minerals, as evidenced by the modified mining contribution Index (IVGP-BP). 10 of the 20 countries in which the mining industry contributes the most (the highest GPI-BP) rose one or two positions higher, according to the world Bank's country classification, between 1999 and 2019. Based on detailed data from the mining sector, such as mining, exports, prices, rents for mineral resources, mineral exploration expenditures, and state budget revenues, the current situation for 2019 is analyzed, as well as trends regarding the contribution to the development of the socio-economic level of the mining industry for 1999-2019.

This work was carried out as part of research on the development of methods for the intelligent analysis of medical thermometric data. These methods are designed to create a consultative intelligent system for the diagnosis of breast cancer. We propose a new approach to the formation of a feature space based on microwave radiothermometry data that are designed to detect malignant tumors. In the process, about 200 new signs were obtained and tested. Based on them, we created an algorithm for the localization of tumors in the mammary gland. This algorithm is a weighted voting algorithm that is configured using a genetic algorithm. The resulting localization algorithm can achieve an accuracy over 70% in test samples.

The analysis of the use of a private car fleet owned by a large number of owners, which was previously in the hands of a single carrier, was performed. The results of the analysis showed that there are cases when the owners of rolling stock, regardless of the carrier's capabilities, send their empty cars in the opposite direction, which reduces the carrying capacity of the railway and leads to losses. To increase the interaction between the carrier and the operator, it is proposed to create a commercial dispatch circle as part of the traffic control center of the traffic management Directorate. The dispatcher of this division provides round-the-clock control over the progress of the operator's (customer's) cars on the road polygon in accordance with the application submitted by them, from the moment of receipt at the inter-road junctions to their arrival and submission for unloading on the way of General and non-public use of consignees at the destination station. The proposed measures help to increase the productivity of cars, reduce their working fleet, operating costs and the cost of transporting goods. The efficiency of the dispatch circle is determined.
