Dear colleagues! Defender of the Fatherland Day embodies the strength and power of the Russian state. Military service in Russia has always been especially respected as a matter of devoted, courageous and strong people who defended the freedom and independence of their native land at different times in our history. So, the day of February 23 has long gone beyond professional boundaries and has become truly popular - a holiday for every citizen of Russia, a special day for everyone who loves the country and respects its history. On this day, we honor real men, those who know how to be a support and protection, who multiply the wealth and glory of the country by their labor. With all my heart I would like to wish the male part of our large scientific team success in creative activities and professional achievements, fortitude, wisdom and audacity in solving scientific and other tasks, persistence and courage. Peace on you, goodness, warmth and festive mood! Acting director of FRS KSC SB RAS A.A.Shpedt
