A brief analysis of the literature indicates that this problem remains poorly understood. At the same time, modern historiography, including local historiography, actively studies various forms of relations between the government and the population. According to the researchers, the \"discussion\" of various draft laws and decrees, the \"introduction\" of their own proposals and comments to them were among the forms of \"dialogue\" of citizens with the authorities at that time. The work uses messages published in the republican newspaper \"Soviet Bashkiria\"; unpublished letters from readers received by the editorial office of the central publication \"Rural Life\"; citizens' proposals recorded in the party documents of the Bashkir regional Committee of the CPSU. The use of several types of sources allows you to achieve a certain degree of objectivity, however, they do not represent the full picture. The specific proposals made by citizens allow us to find out the level of socio-political activity, the development of public interests and preferences of the population of the republic during this period. In the discussion of the draft law, the population of Bashkiria was less active compared to neighboring regions. It is concluded that the proposals made were sometimes quite contradictory. On the one hand, some of them concerned the further improvement of social protection, social status, remuneration of collective farmers and pensioners, on the other, they demanded stricter Soviet legislation in the field of personal subsidiary farming, labor discipline. Thus, there were proposals on the need to include all collective farmers in trade union organizations, increase pensions, etc. Citizens were concerned about the lack of collective farm democracy, some advocated greater restriction of personal subsidiary farms. However, in general, the proposals made by the commission were not taken into account. The significance of the amendments to the draft law is that they indicate an increasingly increasing political activity of the population, including rural ones, and their interest in the political and socio-economic events of the era.","PeriodicalId":220280,"journal":{"name":"Izvestia Ufimskogo Nauchnogo Tsentra RAN","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124784744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ukrainians are the largest group of Protestants in the studied regions, having a \"foreign\" origin. The materials are presented in comparison with data on the general sample of believers. It was found that the systems of identities in the representatives of both control groups are similar; the most important are religious and family identities, the last place in terms of importance is occupied by ethnic identity. At the same time, the results of the research showed that for Ukrainian respondents, religious and family identities are of greater importance, while civil and ethnic identities are of less importance, compared to respondents from the general sample. The greater commitment of Ukrainians to biblical values may be due to the fact that evangelical Christianity historically has more rooted traditions in Ukraine than in Russia; believers who were born and lived for some time on the territory of Ukraine realize evangelical paradigms more fully in their lives.","PeriodicalId":220280,"journal":{"name":"Izvestia Ufimskogo Nauchnogo Tsentra RAN","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121627345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the promising directions of biotechnological assessment of the resistance of existing and newly created genotypes of cereals to this abiotic stress factor for breeding purposes is the use of embryo culture in vitro, when embryos of the particular stage of development are used as explants. Especially promising is the in vitro cultivation of immature embryos that are at the critical stage of autonomy. Such embryo does not depend on the physiological factors of the maternal individual and is able to independently give rise to a full-fledged regenerant under adequate in vitro conditions. At the same time, to identify the stage of autonomy, complex cytophysiological studies of the embryo in the dynamics of development from the zygote to the mature structure are necessary. Embryonic analysis is also necessary during evaluation of the obtained regenerants in the laboratory ex vitro and especially in the field in vivo conditions. The review article, using the example of spring soft wheat, presents some results of comprehensive investigation by the researchers of the plant physiology laboratory UIB UFRC RAS on the use of cytophysiological data to identify the critical stage of embryo autonomy, as well as on the application of the obtained results in the elaboration of biotechnology of embryo culture in vitro. Together with the researchers of the laboratory of breeding and seed production of spring wheat of the RIAS UFRC RAS, the prospects of using culture in vitro of immature autonomous embryos in the creation of drought-resistant hybrid wheat lines are shown.

The purpose of the article is to identify ethnographic materials about the Russian population, which over the past centuries formed the demographic majority and largely determined the ethnic processes in the region. The method of research is a historical and comparative analysis of information about the Russian population of the past centuries with the field materials of the author of the article collected in recent decades. It is revealed that the materials of V.S. Russian Russians of the Zlatoust district of Ufa province, immigrants from Kungursky district of Perm province, that is, representatives of the North Russian ethno-cultural tradition. M.V. Kolesnikov in the late 1880s described the customs and customs of the Russian population of Belebeyevsky and Ufa counties, whose ethnic culture formed by the fusion of traditions of immigrants from different provinces of Russia, especially the Central Russian strip, and interaction with local peoples. Priest K. Yevlantiev in 1878 described the economic activities of the Belebeyevsky district, and the priest M.V. Burdukov in 1905 - the Menzelinsky district of the Ufa province. Their materials allow us to study the process of adaptation of the Russian population to local conditions. Since the 1840s, the newspaper has published information about folk and religious holidays held in villages and cities, where representatives of different ethnic groups, estates, confessions gathered. In the 1860s - 1870s, R.G. Ignatiev presented information about the days of Semik, Trinity, Annunciation, St. George's Day, which were special for the peasants of the Ufa province. Thus, the newspaper's materials provide a variety of information on the ethnic history, economic activity, material and spiritual culture of the Russian population of different counties, their regional features in chronological frames from the 1840s to 1905, ethnocultural processes in the region.

Combined pollution has a more pronounced adverse effect on plants and soil biocenosis than each pollutant alone and leads to a very rapid loss of soil fertility. The aim of this work was to screen for new strains of hydrocarbon-oxidizing microorganisms resistant to elevated concentrations of sodium chloride and heavy metals. Isolation of strains of microorganisms from samples of technogenically contaminated soils from the territory of the Republic of Bashkortostan was carried out by the method of enrichment cultures on a liquid mineral medium of Raymond with oil. The hydrocarbon-oxidizing activity of the isolates was determined by the degree of destruction of the aliphatic oil fraction by the gas chromatographic method after extraction with hexane. The resistance of strains to the presence of sodium chloride and heavy metals (Zn, Co, Cd, Cu, Pb, Ni) was established by their growth on meat-peptone agar with various concentrations of NaCl or salts of these metals. Of the 14 isolated strains, 6 were selected, most actively growing on a solid medium with oil. The highest abundance and the most significant hydrocarbon-oxidizing activity during cultivation in a liquid medium with oil was found in strain 22 (the degree of oil biodegradation was 93.0%). All microorganisms were halotolerant and grew at 5 and 7% sodium chloride in the medium, but cultures 11 and 41, which withstood a NaCl concentration of 10%, turned out to be the most resistant to salinity. Strains 33.1 and 33.2 had the highest resistance to the action of metals. Lead and zinc were the least toxic to microorganisms. The results obtained should be considered preliminary, and the isolates themselves need further research with a view to their possible application in ecobiotechnology.","PeriodicalId":220280,"journal":{"name":"Izvestia Ufimskogo Nauchnogo Tsentra RAN","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115281182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
