Because of the decline of the epidemiological situation in the Republic of North Ossetia-Alania, the Organizing and Program Committees were forced to make a decision to move the Conference to a web-hosted event. 

Thus, the Conference will take place in the same dates which were announced before (from 20 till 25 September, 2021) not in mixed but completely in online format via Zoom. The link for connection will be sent on September 19, 2021 to all registered participants.
