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.

Abstract
Toxicity of welding aerosol significantly affects the choice of the type of electrodes for arc welding. Modern research methods allow determining the content of divalent and trivalent manganese particles in the solid component of welding aerosol. Studies were carried out to determine the ability of detecting the presence of ions in the most toxic tetravalent manganese in the solid component of welding aerosol. The possibility of using the method of RFS analysis for fixing manganese ions in the Mn4+ state in welding aerosols is shown. 9 Ref., 3 Tables, 2 Figures.
