Text recycling

4.1. The submitted article (excluding the bibliography) should not have more than 15 percent of recycled text (text used in other publications of the author).
4.2. The journal allows text recycling only for including necessary definitions, formulating base principles etc for reading the article without additional sources. This case of text recycling is not self-plagiarism.
4.3. If authors consider necessary for reader to study some materials on similar subject or not included in the article, they can make the bibliography sufficiently complete to find these materials.
