Dear authors!

Starting from 2018, all published articles will be assigned a DOI (digital object identifier) - a digital object identifier that determines the permanent location of the object on the Internet, its name and metadata.

The presence of a DOI article is:

- standard adopted by all leading publishers of the world;

- a permanent path to the address of a particular article on the Internet;

- increasing the indexability and citation of the article;

- increase the credibility of the publication;

- automatic hit of the link to your article in the Web of Science, Scopus, EBSCO, DOAJ, etc. when quoting in the journal included in these databases, and getting your own citation index.

Please note that it is necessary to specify the DOI at every citation of your article. Also, the DOI indication is important for works to which it is assigned. You can check for DOIs at http://search.crossref.org/.
