The article focuses on the publications of Russian émigrés, published in the first ecclesiastical printing house in the Kingdom of Serbs, Croats and Slovenes, which opened in 1925 in the city of Niš. The article describes the history of its foundation, as well as the reorganization of its activities during the economic crisis of the first half of the 1930s, which opened another “Russian episode” (besides the foundation itself) in the history of Niš printing house. At that time the main role belonged to the two Russian refugees living in Niš - Artem Bellubekov, who was appointed to the position of the head of the printing house, and Nikolay Makarenko, who worked as the main binder and graphic artist. The article also contains a review of publications by two authors - Alexander Petrovich Kurachinov and Elisaveta Glukhovtsova, whose books were published in the printing house “Saint Emperor Constantin” in the city of Niš in the 1940s. The authors hope that this article will play an important role in informing contemporary researchers of the Russian émigré́ about the creative work of A.P. Kurachinov and E. Glukhovtsova, which so far has not come to the attention of scholars. The collected material can be useful for further study of the role of Russian emigration in southeastern Serbia and its impact on the cultural development of this region. The material can also contribute to a deeper understanding of the specifics of activities of representatives of émigré́ movement in this territory, which were free of influence of large emigrant centers. The authors of the paper also pay attention to the fate of the printing house of the Pochaev Lavra, which continued its existence in the structure of the printing house “Saint Emperor Constantin” of the city of Niš.

One of the most prominent cultural figures among Russian emigrants of the first half of the 20 th century living in Niš was Alexander Petrovich Kurchaninov -Russian Grandad Alexander (Grandpa Rus) as he called himself. As a working assis-

The paper presents and analyzes the efficiency of a solar plant for the production of thermal energy, ie the preparation of hot water (DHW) in the hospital in Subotica. At the analyzed facility, solar collectors provide the complete needs of the hospital for hot water from spring to autumn, while in the second part of the year, the required thermal energy is obtained from additional sources. The solar plant consists of 144 solar collectors, where the total gross area of the collector is 362.6 m 2 and the installed power of the plant is 253.8 kW. During the analyzed period from 2014 to 2017, a total of 558 MWh of thermal energy was produced, ie energy equivalent to 58,613.43 kg of fuel oil was saved. This thermal energy was used for the needs of the kitchen, laundry, central sterilization, heating of the operating room, and etc.

Since in the alternative history as a genre of literary fiction, the bifurcation point, namely the fantastic assumptions that at some of the turning points in history there was an alternative development of events, has a central role, this genre of literature has become quite useful in the analysis of the perception of national history through examination of the impact of certain events on the historical development of a given culture. In this paper, through the prism of the development of the genre of alternative history in Russian literary fiction, we look at historical events which stand out as central from the perspective of Russian authors, analyze the motives and the plot structure of these works, and propose a chronological classification of narrative worlds. The paper focuses on the most significant works of Russian literature of this genre, among which we have singled out the cycle of novels on alternative history of the Russian Middle Ages under the common title “Eurasian Symphony” (2000-2005) by Holm Van Zajchik, the short story “The Second Life of Napoleon” (1917), the novel “Pugachev the Victor” (1924) by Mikhail Pervukhin, the novel “The Island of Crimea” (1979) by Vasily Aksyonov, as well as the novels about the alternative history of the Second World War by Andrei Lazarchuk, Sergei Sinyakin and others.
