May 22, 2020 - site maintenance:

the journal's site is in maintenance. We are upgrading the OJS (system that manages the journal) and several technical problems and bugs have appeared. In the meantime, the appearance of the site has changed and is minimal. It is however still possible to consult articles and precedently published issues.

It is also still possible in principle to submit articles, but we recommend you to postpone submissions on the site of the journal during the upgrading. Send us submission by e-mail (

Thank you for your patience.
