Vol. 10 No. 1 (2022)
The work on this issue was carried out at a difficult time, after Russia declared war to Ukraine, starting to invade the country by February 24. Part of our editorial staff, as well as Ukrainian authors whose articles are published in this issue, worked in conditions of constant alarms and threats of missile and air strikes, sounds of explosions and gunfire. The editors condemn Russian aggression of the Ukrainian people. They also thank all the researchers over the world, who express support to the Ukraine beyond the context of the Journal. More indirectly, indeed, the Russian violence is also against France, sister-country of Ukraine, and more generally against science and international cooperation.
