    Abstract:
    The article considers the current state of the water supply system of the Krasnodar Territory from the point of view of municipal infrastructure management, special attention is paid to the problem of network wear. Statistical data on the provision of the population with water, the scale and age of the network infrastructure, as well as the dynamics of reducing network wear over the last decade are presented. The main problems associated with high physical wear of water supply networks and its consequences for management were analysed: an increase in accidents, significant water losses, financial difficulties of enterprises and the need for large-scale modernisation. The measures taken by regional authorities to update networks (modernisation programs, investments, concession agreements and national projects) and management approaches to solving the identified problems are described. As a result, conclusions were formulated on the need for integrated planning, sufficient funding and st

    Author:
    Anna A. Saenko
    Work direction:
    Особенности сопровождения и поддержки семей, имеющих детей с отклонениями в здоровье, развитии и поведении
    Abstract:
    The article underlines the importance of the parental role in the development of speech and help children overcome difficulties in sound wear. The key factors of successful correction are continuous cooperation between parents and professionals, as well as the creation of a stimulating environment for the controlled and purposeful development of sound wear in children with intellectual impairment of light degree

    Глава 2. Наука
    Abstract:
    The article is devoted to the development of the direction of work on the creation of qualitatively new innovative solutions to ensure the reliability of connections of machine elements. The recommendations are based on the analysis of studies on wear process of the fixed joints of machine elements during microdisplacements in contact under the influence of vibration at high temperatures. It is established that physical and chemical processes occurring in the area of actual contact of the joint elements are varied and the effect of temperature on tribological characteristics of frictional contact is complex, since with an increase in temperature the reduction of worn-out volume can occur as well as increase of it. To predict the resistance of the contact to fretting, it is necessary to conduct a force analysis on the contact and determine the spectral composition of vibrations affecting the friction contact.

    Парадигмы современной науки
    Abstract:
    The problem of improving the reliability and service life of friction units operating in extreme operating conditions, especially at high temperatures, is mainly solved by the use of ceramic materials. The paper analyzes the tribotechnical properties of ceramic materials based on partially stabilized zirconium dioxide and formulates proposals for the optimal selection of friction pairs based on experimental data.
