Free-cutting steel gains specific working properties thanks to the high content of sulfur and phosphorus. These elements, especially sulfur, have a rather high tendency to segregation. Therefore, segregation defects in free-cutting steel continuously cast billets can be significantly developed. The aim of the work was to study the influence of the chemical composition of freecutting steel and casting technological parameters on the quality of the macrostructure of continuously cast billets. A metallographic assessment of the internal structure of cast metal made of free-cutting steel and data processing by application of correlation and regression analysis were the research methods. The array of production data of 43 heats of free-cutting steel of grade A12 was studied. Steel casting on a five-strand radial type continuous casting machine was carried out by various methods of metal pouring from tundish into the molds. Metal of 19 heats was poured with an open stream, and 24 heats – by a closed stream through submerged nozzles with a vertical hole. High-quality billets had a cross-sectional size of 150×150 mm. The macrostructure of high-quality square billets made of free-cutting steel of A12 grade is characterized by the presence of central porosity, axial segregation and peripheral point contamination, the degree of development of which was in the range from 1.5 to 2.0 points, segregation cracks and strips – about 1.0 points. In the course of casting with an open stream, almost all of these defects are more developed comparing with the casting by a closed stream. As a result of correlation and regression analysis, linear dependences of the development degree of segregation cracks and strips both axial and angular on the sulfur content in steel and on the ratio of manganese content to sulfur content were established. The degree of these defects development increases with growing of sulfur content in steel of A12 grade. These defects had especially strong development when sulfur content in steel was of more than 0.10%. To improve the quality of cast metal, it is necessary to have the ratio of the manganese content to the sulfur content in the metal more than eight.

The experience of clinical testing of the personal telemedicine system ‘Obereg’ for remote monitoring of patients at the intensive care units of leading Russian clinics is described. The high quality of communication with the remote receiving devices of doctors, the accuracy of measurements, resistance to interference from various hospital equipment and the absence of its own impact on such equipment were confirmed. There are significant advantages compared to stationary patient monitors, in particular, for intra and out-of-hospital transportation of patients.

The transthoracic echocardiography made by multifrequency probes with support of the mode of the second harmonic imaging, is a competitive method for visualization of the main coronary arteries and allows to estimate coronary blood flow with high quality. Of course, the method has considerable restrictions, most important of which is the low spatial resolution of a method, due to small acoustic window. Because of this the transthoracic visualization of coronary arteries perhaps will not become the leading method of anatomic reconstruction of separately taken coronary artery and especially all coronary arteries system. However uniqueness and indisputable advantage of this method is an opportunity to noninvasively estimate a coronary blood flow both once, and in dynamics.

Subject. This article deals with the issues of social justice and a high quality of life, creating favorable economic and social conditions. Objectives. The article aims to assess the rate and changes in poverty in Russia and the Republic of Bashkortostan and develop complementary measures to reduce it. Methods. For the study, I used the methods of logical, comparative, economic and statistical analyses, the results of sociological studies, and official statistics. Results. The article highlights additional measures to reduce poverty in the region, including the establishment of a minimum social standard of living in each particular region that determines the poverty rate. Conclusions. Various factors, such as economic sanctions, economic slowdowns, territorial and regional imbalances, lead to living standards decline and poverty rise.

The article is about the role of the family in the education and formation of children and, especially, in the life and development of autistic children. It describes the problems their family is facing and the need for counseling to parents with autistic children. The reaction to finding the diagnosis of autism varies from one family to another and may encounter a large variety: from disbelief, anger, guilt, helplessness, devastation, surprise, or even rejection of the child, to understanding and relief when finally the parents have an explanation for their child behaviors. Early intervention is important in psychological sustaining of the parent, as parent involvement in the recovery of the child with autism has a determinant role in his development and in ensuring a high quality of life of the child and the life of the hole family. The response to a child's autism diagnosis varies from one family to another. The family goes through a variety of disbelief, anger, guilt, helplessness, devastation, surprise, or even rejection of the child, to understanding and relief. Early intervention is very important in the psychological support of the parent. Because any change disturbs the family equilibrium. A diagnosis of autism changes not only the life of the diagnosed child, but also the life of family members. All the resources are focused on the need of the child. Although each parent is different, after diagnosing the child with autism, all parents are overwhelmed by confusion, shock and denial. Parents' feelings can be influenced by how their children's situation affects different aspects of life - it has an impact on service, on social life and all their personal life. If we look at the family as a system and when a disturbing factor appears, all parts of the system are affected. The involvement of parents in the recovery of the child with autism has a decisive role in its development and in ensuring a high quality of child's life and family life.

Food is often wasted due to real or perceived concerns about preservation and shelf life. Thus, precise, accurate and consumer-friendly methods of indicating whether food is safe for consumers are drawing great interest. The colorimetric sensing of biogenic amines released as food degrades is a potential way of determining the quality of the food. Herein, we report the use of genipin, a naturally occurring iridoid, as a dual colorimetric sensor for both oxygen and biogenic amines. Immobilization of genipin in edible calcium alginate beads demonstrates that it is a capable sensor for amine vapors and can be immobilized in a non-toxic, food-friendly matrix.

This study provides a retrospective analysis of work to ensure high quality of medical care in an unfavorable epidemic situation. The consequence of COVID-19 was the implementation of a program to prevent the spread of infection, the re-profiling of medical institu-tions, and the introduction of restrictive and anti-epidemic measures. The experience of our work has shown the effectiveness of changing the order of med-ical care, the organization of the functioning of de-partments and patient routing. The study reflects the measures implemented in the hospital departments, the Department of clinical and laboratory diagnostics, radiation diagnostics and pathology Department. To ensure the safety of patients, it was decided to place patients on a single bed according to the type of infec-tious boxes. The safety of employees was ensured by the use of personal protective equipment, minimiza-tion of contact time with patients, and preventive weekly examination of staff for SARS-CoV-2 infection. The organized and well-coordinated work of the en-tire staff of the institution made it possible to prevent the spread of COVID-19 among employees, to detect cases of infection in a timely manner, and to carry out appropriate isolation and monitoring measures. At the time of completion of infectious diseases departments, the mortality rate among patients was less than 9%. Our experience in reorganizing a multi-specialty facil-ity can be used in the future when working with pa-tients who have undergone COVID-19, as well as in the context of a worsening epidemic situation.
