The journal applies the Creative Commons Attribution-NonCommercial 4.0 International License CC BY-NC to all articles. It means that all articles become freely accessible once published. This allows anyone to read, download, save, copy, print and distribute the paper in any medium or format, and remix, transform and build upon the paper for any purpose, including commercially, as long as the original authors and source are cited. In doing so, no permission is required from the authors or the publishers. For full details on Creative Commons licensing conditions check Creative Commons.
No transfer of copyright is necessary in order to publish a paper in the journal. The authors (or the holder of authors’ copyright) retain the full rights over their work without any restrictions.
If any illustration or table is reproduced from a journal article, permission should be obtained from the copyright holder. A suitable acknowledgement of any borrowed material should always be made.
For any reuse or redistribution of an article, users should also make clear the license terms under which the work was published.
