Low stiffness of the machine could be improved by polymer concrete pouring into cavities of cast-iron structural parts. More perspective design pattern is to embrace machine LBS by concrete envelopes, inserted one-inside-other. It should provide outer ...2023-01-24 -
Разнопрочная дорожная одежда
(БНТУ, 2022)The article discusses the road characteristics of roads, the strength of which varies along the width of the carriageway. This stability makes it possible to identify the impact of the traffic structure. These include the occurrence of traffic load and the occurrence of water-thermal factors. The design methods that exist today do not fully take into account these factors. This ...2023-01-24 -
Методика расчета устойчивости проходческого комбайна стреловидного типа
(БНТУ, 2022)The condition of balancing state of a tunneling machine of a swept type under the action of external forces on the cutter and friction forces between the tracks and the working soil is considered.2023-01-24 -
Разработка прототипа приложения для улучшения экологии города
(БНТУ, 2022)The problem of ecology is a top question in the 21st century. The planet itself is suffering from the impacts of human activity. We’ve noticed that lots of people would like to contribute to the fight against climate change, deforestation, soil depletion, etc., and an app to help them out in this task turned out to be a reasonable solution.2023-01-24 -
Получение оксидных покрытий на поверхности вентильных металлов с применением высокочастотного импульсного микродугового оксидирования
(БНТУ, 2022)The disadvantages of traditional methods of microarc oxidation are the long processing time (up to 120 min) for the formation of oxide layers of the required thickness with the required properties and, accordingly, high energy costs. Such a long duration of the traditional MAO process is due to the fact that the thickness of the formed oxide layer is determined by the number of ...2023-01-24 -
Роль гипербарической оксигенации в оптимизации костного ремоделирования у пациентов с переломами костей голени
(БНТУ, 2022)The effect of hyperbaric oxygenation in patients with complex segmental fractures of the lower leg bones was studied. The results obtained indicate the optimization of bone remodeling with the predominance of bone-forming processes in it, as a result of which the time of fusion was reduced.2023-01-24 -
