Church Slavonic Canon and its Interpretation during the Baroque Period: based on the Book “Runo orošennoe” by Dimitry Tuptalo, Metropolitan of Rostov
No full textThe present paper deals with the book by Dimitry Tuptalo, Metropolitan of Rostov, titled “Runo Orošennoe” compared with the earlier work of the same author “Chuda Presviatij i Preblagoslovennoj Devy Marii” (The Miracles of the Holiest an the Most Blessed Virgin Mary”) as well as with the contemporary West European religious literature in the aspects of structure, language and symbolic and metaphoric images. The conscious orientation of Dimitry on the Byzantine and Church Slavonic canon as well as its creative interpretation based in the baroque framework are stressed
OUTSTANDING RUSSIAN SCIENTISTS: DIMITRY AND ELENA WENTZEL
No full textThe paper presents the scientific biographies of two outstanding Soviet mathematicians and teachers Elena Sergeevna and Dimitry Alexandrovich Wentzel. The main attention is paid to the restoration of genuine events related to the scientific, pedagogical and social activities of these people. The paper extensively uses published materials, as well as oral memoirs of the participants of these events – friends and acquaintances of our heroes. Special attention is paid to the history and activities of the country’s largest military university – the Air Force Engineering Academy named after Zhukovsky (VVIA). Almost the whole life of the Wentzels was closely connected with the Academy. The life and customs of the Petersburg (Petrograd) University in the 1920s are described in detail, where E.S. Wentzel learned. The paper provides the information about many famous professors and teachers of both universities, reconstructs and analyzes the pedagogical activities of E.S. Wentzel in VVIA and MIIT (Moscow), her scientific and publishing activities in the field of probability theory and operations research. The author reconstructs and dwells on her literary activity under a pen name I. Grekova. As a writer, E.S. Wentzel contacted with the famous literary men (A.T. Tvardovsky, K.I. Chukovsky, A. Galich, etc.). The paper also describes the scientific activity of D.A. Wentzel in the field of ballistics, his contribution to publishing textbooks for military universities, his experience in training highly qualified personnel (candidates, doctors, academicians), his scientific and organizational activities (the creation of the Faculty of Armaments in the VVIA, the foundation of the Academy of Artillery Sciences of the USSR and others). The special aim of the paper was to recreate the human images of Elena and Dimitry Wentzel
“Through the Letter Sent with my Envoys to Kiev” St. Dimitry`s of Rostov Contacts with Kiev and Chernigov in 1701–1709
No full textThe article examines st. Dimitry’s of Rostov contacts with Kiev and Chernigov in 1701–1709. Dimitry’s correspondence is vast, but addressees of the most of the known letters are Dmitry’s Moscow friend and Great Russian hierarchs. Problem of st. Dimitry’s contacts with his Little Russian acquaintances still remain obscure. This article deals with the information of st. Dimitry of Rostov correspondence with addressees in Kiev and Chernigov and the circumstances of Dimitry’s visit to Chernigov in 1704. In time of his episcopal service st. Dimitry exchanged letters with Josaph Krokowski, archimandrit of Kievan Lauras and future metropolitan of Kiev. Letters were sent with agents of both hierarchs. This correspondence was devoted to the publication of the “Lives of the Saints” in the Lavra’s typography. There are no evedencies of st. Dimitry writing letteres to members of Chernigov clergy in 1701–1709, although st. John Maximovich archbishop of Chernigov sent his new books to Dimitry of Rostov. However in february of 1704st. Dmitry undertook a journey to Chernigov that left almost no traces in sources. The main evidence is record of Pachomios of Roman, a Moldavian ascetic, about himself meeting Rostov metropolitan in Chernigov in 1704. This trip was an exeptional event and could be connected with the demise of Parthenios Neboza, metropolitan of Holmogory, who died suddenly on 2 january 1704 in Yaroslavl. Author concludes that Dimitry of Rostov in 1701–1709 was not isolated from his old friends and mantained his ties with educated clergy of Little Russia during the years of his Episcopal service in Moscow and Rostov

No full textNo impacts of azoxystrobin-based fungicide on bumblebee colonies in dose-response experiment mimicking fungicide decline
No full textFungicides are often applied to flowering crops despite their potential to negatively affect bees. Azoxystrobin is a systemic fungicide that is applied to a wide variety of crops globally. Recent studies suggest that azoxystrobin can harm bees at field-realistic concentrations but effects were inconsistent between bee species, crops and studies. Contrary results may in part be due to subtle differences in exposure levels.To assess the potential impacts of the azoxystrobin-based fungicide Ortiva on the colony development of bumblebees (Bombus terrestris), we conducted a highly replicated dose-response experiment with a unique study design. Rather than individuals, 42 colonies with the possibility to forage freely were exposed to degrading rather than constant fungicide concentrations through syrup. One set of colonies received a field-typical sequence of doses and additional sets of colonies received either a multiple or a fraction of these doses (factors: 0, 0.5, 1, 2, 4, 8).Preliminary results show, however, no impact on colony growth even at high doses despite similar syrup consumption rates. Azoxystrobin may reduce pollen quality rather than affect bees directly as no effects were observed when exposure was exclusively through syrup while a previous semi-field experiment found negative effects on B. terrestris only when colonies were exposed through foraging on a high-quality pollen source. Alternatively, the absence of impacts in our study could be due to the potential disappearance of volatile co-formulants that were previously shown to harm bumblebees
