Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

The majority of existing structures have welded joints. It is of considerable interest to determine the differences in acoustic emission for various types of welded joints and change of the properties of materials in operating structures, which have welded elements after long-term service, taking into account the time and probable violation of service conditions. The data of testing samples from such materials demonstrate the high sensitivity of acoustic emission method to welded joint type, and to changes of weld service properties. 9 Ref., 2 Tabl., 14 Fig.
