With great sadness and regret that we received the news of the death of Professor Volodymyr V. Panasyuk.
We had a long-term, deep friendship with Professor Volodymyr V. Panasyuk. He was a mentor to many of our actions, and above all, a kind and devoted friend, thanks to whom we learned not only about the achievements of the Karpenko Physico-Mechanical Institute of the National Academy of Sciences of Ukraine, but also about his beautiful homeland.
