М.; Шок, К. П.; Dziadykevich, Yu.; Popovych, P.; Vitroviy, A.; Rozum, R.; Chorna, O.; Zakharchuk, О.; Galysh, N.; Tsidylo, Z.; Shok, K.В роботі висвітлено проблематику сумісності компонентів при створенні тугоплавких та міцних композитних матеріалів в цивільній інженерії. Проаналізовано праці провідних вітчизняних та зарубіжних вчених з даної проблематики. Виділено основні чинники, які впливають на сумісність компонентів при термодинамічних твердофазних процесах створення композитних матеріалів. Дано рекомендації щодо вибору металевої основи і зміцнючого оксиду із врахуванням споріднення до кисню металу основи і елемента, що утворює оксид. Досліджено твердофазну взаємодію і розчинність матеріалів при високих температурах. Наведено способи одержання композиційних матеріалів із використанням несумісних компонентів. The work highlights the problem of thermodynamic and kinetic compatibility of components in the creation of fire-resistant and strong composite materials in civil construction. The works of leading domestic and foreign scientists on this problem are analyzed. The kinetics of the interaction of temperature, pressure, structural features, the degree of compactness of the material and the external environment are considered. Areas of practical application of solid-phase reactions are indicated. Attention is paid to the protection of refractory materials from high-temperature gas corrosion. The compatibility of the boride coating with refractory metals was investigated. The interaction of titanium diboride with iron and its alloy was studied. It has been proven that iron alloys are promising for their use as a basis for composite materials. The laws of the compatibility process of components during the development and operation of high-temperature materials in civil engineering were studied. The main factors influencing the compatibility of components during thermodynamic solid-phase processes of creating composite materials are highlighted. Recommendations are given for the selection of the metal base and strengthening oxide, taking into account the affinity of the base metal and the oxide former for oxygen. The solid-phase interaction and solubility of materials at high temperatures were studied. Methods of obtaining composite materials using incompatible components are given.Item Дослідження безпеки дорожнього руху у м. Тернополі(ЦНТУ, 2023) Попович, П. В.; Розум, Р. І.; Мурований, І. С.; Буряк, М. В.; Березька, К. М.; Петринюк, Н. А.; Лоїк, І. О.; Popovych, P.; Rozum, R.; Murovanyi, I.; Buryak, М.; Berezka, K.; Petrynyuk, N.; Loik, I.Стаття присвячена проблемі дослідження проблематики безпеки дорожнього руху в місті Тернополі з структуруванням встановлених фактичних недоліків за основними показниками. У результаті проведеного аналізу руху транспортних потоків у ранковий період встановлено найбільш проблемні ділянки ВДМ. The article is devoted to the problem of researching road safety issues in the city of Ternopil with the structuring of established actual deficiencies according to the main indicators. As a result of the analysis of traffic flows in the morning period, the most problematic sections of the street and road network were identified. In general, it is observed that in the evening peak period, the speed of traffic flows on the street and road network is significantly lower than in the morning peak period. In order to analyze road traffic safety in the city of Ternopil, a cartographic method was used, which involves superimposing on the map data arrays regarding traffic accident statistics for 2018-2020. This approach makes it possible to determine the places of concentration of road accidents, however, during the analysis, it was found that road accidents in Ternopil mostly occur along the main streets without clearly defined places of concentration. In this regard, a conditional indicator of the danger of transport corridors of Ternopil was derived, which is determined by the ratio of the number of road accidents with victims to the total length of the street, which also allows analyzing the predominant location (clustering) of road accidents with victims in each district of the city. The current policy and practices of Ternopil in the field of road safety management need improvement. In the city, repair work is regularly carried out to maintain the roadway and technical equipment in proper condition, but the quality and volume of the work performed do not fully cover the need to ensure traffic safety and provide information to road users. In general, it can be stated that Ternopil is a city that is just starting proactive actions in the field of traffic safety ("starting city"). In this, it favorably differs from the vast majority of other regional centers, in which the problem of traffic safety is not even discussed so far, and consideration of this issue in terms of sustainable urban mobility of the Ternopil urban territorial community.Item Дослідження стану транспортної інфраструктури міста Тернополя(ЦНТУ, 2023) Попович, П. В.; Маяк, М. М.; Розум, Р. І.; Буряк, М. В.; Березька, К. М.; Коваль, Ю. Б.; Мишко, С. А.; Popovych, P.; Maiak, M.; Rozum, R.; Buryak, М.; Berezka, K.; Koval, Yu.; Myshko, S.Стаття присвячена проблемі дослідження стану транспортної інфраструктури міста Тернополя з метою подальшої розробки плану сталої міської мобільності для Тернопільської МТГ. Аналіз виділення фінансування та освоєння коштів показав, що протягом тривалого часу відбувається недофінансування робіт пов’язаних з транспортною інфраструктурою м. Тернополя. Фактичні показники освоєння фінансових ресурсів виділених з бюджету громади на покращення стану ВДМ за 2020 рік не досягли планових показників на 36,4%. Згідно з даними з бюджету громади на реалізацію заходів Програми розвитку велосипедної інфраструктури міста на 2020 рік передбачалося виділення 2000,0 тис. грн, проте, фактично заходи не профінансовано. The article is devoted to the problem of researching the state of the transport infrastructure of the city of Ternopil with the aim of further developing a sustainable urban mobility plan for the Ternopil urban territorial community. In order to meet the existing needs of passengers in quality transport service, it is necessary to provide a sufficient number of buses with a large and medium passenger capacity, however, in accordance with the principles of sustainable urban mobility, the priority of the community's transport policy should be environmentally friendly electric transport. In connection with the growing level of motorization of residents of the Ternopil urban territorial community and the correspondingly growing demand for the use of individual transport, the most difficult situation with an insufficient number of parking spaces is observed in the central part of the city, where the vast majority of objects of attraction for making trips are concentrated. Maintenance, repair and renewal of community transport infrastructure facilities is carried out by the relevant executive bodies of the TCC using the approach of annual planning of financing the necessary measures based on approved industry programs. Regardless of various sources of funding, such as the city budget, the state budget, investments, loans, funds of individuals and legal entities, the implementation of measures largely depends on the funds of the local budget. The analysis of the allocation of funding and the utilization of funds showed that for a long time there has been underfunding of works related to the transport infrastructure of the city of Ternopil. The actual indicators of utilization of financial resources allocated from the community budget for improving the condition of the street and road network for 2020 did not reach the planned indicators by 36,4%. According to the data from the community budget, 2000.000,0 UAH was supposed to be allocated for the implementation of the measures of the City Bicycle Infrastructure Development Program for 2020, however, in fact, the measures have not been financed.
