Okno Magazine (Russian: Журнал "Окно", literally "Window") is one of the Russia's leading literary magazines, which was founded in 1923 in Paris by Mikhail Zetlin, the Russian émigré writer.
 Three paper-based issues were published in 1923 and in 1924.
 In 2007 Okno was re-established as a web-only magazine of poetry in Russian.
 It publishes Russian poetry, including prose poems and visual texts, translations of poetry from other languages into Russian, as well as literary heritage and essays/articles on poetry.
 Since autumn 2010 "Okno" has also been publishing fiction, e.g. novellas, short stories and fragments of novels.
 The magazine is currently edited by Anatoly Kudryavitsky, a distant relative of Mikhail Zetlin, and has some well-established poets, e.g. Konstantin Kedrov, Sergey Biryukov and Elena Katsuba, on the editorial board.
 Dmitri Bavilsky, the prominent Russian novelist and critic, joined the editorial team as the fiction editor in summer 2010.
Lutsk Gymnasium #  21 after Mikhail Kravchuk  is an elementary (grades 1-4), middle (grades 5-9) and high (grades 10-11) school with the specialization in some subjects, determined yearly according to the students' and parents' wishes, recommendations of senior teachers and a stuff phycologist.
Mikhail Borisovich Kogan (Russian: Михаил Борисович Коган ; September 5, 1893 in Zhitomir, Russian Empire – November 26, 1951 in Moscow, USSR) was a well-known doctor, a head of the therapy department of 2nd Moscow Medical Institute.
 He treated well-known people as Samuel Marshak, Martiros Saryan, Dmitri Shostakovich, Vyacheslav Molotov and others.
Dmitri Victorovich Anosov (Russian: Дми́трий Ви́кторович Ано́сов ; November 30, 1936 – August 5, 2014) was a Soviet and Russian mathematician, known for his contributions to dynamical systems theory.
François Labourie (born 15 December 1960) is a French mathematician who has made various contributions to geometry, including pseudoholomorphic curves, Anosov diffeomorphism, and convex geometry.
 In a series of papers with Yves Benoist and Patrick Foulon, he solved a conjecture on Anosov's flows in compact contact manifolds.
Mikhail Kravchuk (Belarusian: Мiхаiл Краўчук ; Russian: Михаил Кравчук ; born 19 September 1991) is a Belarusian professional football player currently playing for Luch Minsk.
Mykhailo Pylypovych Kravchuk, also Krawtchouk (Ukrainian: Миха́йло Пили́пович Кравчу́к ) (September 27, 1892 – March 9, 1942), was a Soviet Ukrainian mathematician who, despite his early death, was the author of around 180 articles on mathematics.
Mieczyslaw Weinberg composed his Requiem Op. 96 between 1965 and 1967.
 Like other Soviet Requiems such as Dmitri Kabalevsky's it does not set to music the Roman Rite liturgy, but secular poems by Mikhail Dudin, Munetoshi Fukugawa, Federico García Lorca, Dmitri Kedrin and Sara Teasdale.
 The use of anti-war texts links this work to Benjamin Britten's War Requiem, which Weinberg knew well.
Mikhail Kukushkin successfully defended his title, defeating Konstantin Kravchuk in the final 6–3, 6–7(3), 6–3.
