In modern musicology, which studies various polyphonic traditions intensively, it would appear that there are no longer any unknown types of polyphony and undiscovered forms of notating music. The most exotic musical phenomena have been researched and transcribed, and a good many of them have been digitized. Still, one must recognize that the focus of these studies up until now has been predominantly on Western and Central European polyphonic schools, while one significant polyphonic tradition, namely, early Russian polyphony, which, moreover, occupied a fairly extensive historical period, is only now beginning to be investigated systematically. The purpose of this article is to introduce my project involving a critical edition of Russian neumatic polyphony. This edition is the culmination of my work on deciphering neumatic scores of the most festive type of early Russian polyphony—four-part Demestvenny singing (or Demestvo). The object of the present study is the Demestvenny All-Night Vigil recorded in a unique source—a ceremonial illuminated codex belonging to the 17th-century Choir of the Tsar’s and Patriarchal Singing Clerics, which is now kept in the British Library—Add. MS 30063. The edition is planned as part of the dissertation project “The All-Night Vigil in early Russian polyphony,” which I am preparing under the guidance of Professor Dr Christoph Flamm at the Musicology Seminar of the University of Heidelberg. Within its scope, the dissertation examines three types of early Russian polyphony using examples from the All-Night Vigil office. A comprehensive analysis of the hymns themselves will be included in the dissertation but remains outside the scope of this publication.

We consider the author's definition of the social success among adolescents with disabilities as an integrative personality quality. This integrative personality quality is considered taking into account the psychological and developmental challenges of this category of adolescents, reflecting the purposeful achievement of their goals and the ability to use the achieved result for further development, contributing to successful socialization in society based on productive interaction with others. The presented structure of social success is a unity of interrelated components: value-motivational, cognitive-active, personal-creative. The value-motivational component includes achievement motivation that promotes activity, overcoming risk factors and full-fledged socialization; value orientations that determine the moral character, character and direction of behavior of adolescents with disabilities; cognitive interest that helps to reveal abilities, develop imagination, imagination and creative activity. The cognitive-activity component includes theoretical knowledge in the field of personal success, knowledge of social norms and behavioral rules that help adolescents with disabilities to establish social contact and socially successful adaptation; mastering practical skills of conscious, independent activity; interpersonal relationships and social experience that expand social horizons for adaptation in society. The personal-creative component provides for communicative skills that ensure a successful existence in society and help to build full-fledged constructive relationships; creative self-presentation skills that are indicators of personal changes and achievements; project skills and creative self-development that contribute to a positive change in personal qualities and self-expression. The presented structure of social success of adolescents with disabilities is based on the leading ideas of personal-activity, environmental, inclusive and integrative approaches.

We consider the pedagogical conditions that contribute to social success formation among adolescents with disabilities in applied activities in the organization of additional education. The first condition is the involvement of adolescents with disabilities in socio-cultural practices in the process of implementing an additional general education program “Successes of Creativity” containing ele-ments of project activities. This contributes to the creation of a situation of success, the disclosure of the potential of the personality of an adolescent with disabilities through the understanding of their abilities, mastering applied activities. The second condition is the activation of the continuous devel-opment of motivation among teachers of additional education to work with adolescents with disabili-ties, providing pedagogical support and support for this category of adolescents. Pedagogical support is based not only on the programs design, but also on understanding the process of maintaining and functioning of adolescents with disabilities to reveal personality and personal potential as a compo-nent of success. The third condition is the organization of an educational community: a teacher of additional education – an adolescent with disabilities – a parent of an adolescent with disabilities and testing of variable work forms online and offline. The use of potential of family in the educational community (school, institutions of additional education) contributes to the social success of adoles-cents with disabilities, instilling confidence and stability, supporting progress in development. The fourth condition is the reflection on the personal and collective social success among adolescents with disabilities. Comprehension of one's own experience is in reflection, which manifests itself in creative applied activity through communication skills, self-improvement and self-development skills, self-presentation. The achieved personal reflection affects the result of group or collective reflection, and is collective in nature for all members of the group. Thus, the practical significance of the conducted research is determined by the opportunities that open up for teachers of additional education in work-ing with adolescents with disabilities, in the formation of social success in the process of practicing applied activities.

We consider current and insufficiently developed issue of social success of a special group of adolescent children with disabilities. Due to literature analysis, social success of adolescents with disabilities is an integrative personality quality, considering the psychological and pedagogical features of the development of this adolescents category, reflecting the purposeful achievement of their goals and the ability to use the achieved result for further development, contributing to successful socialization in society based on productive interaction with others. The factors contributing to the formation of social success of adolescents with disabilities that influence this process are: objective and subjective factors. The presented research results have scientific novelty and allow expanding the conceptual field of the theory of social education by clarifying the factors contributing to the formation of social success of adolescents with disabilities in the process of practicing applied activities. We determine the practical significance of the research and its results by the opportunities that open up for teachers of additional education in working with adolescents with disabilities and parents of this category of children, considering reasonable objective and subjective factors of social success formation among adolescents with disabilities in organizations of additional education.

Актуальность работы обусловлена возрастающим интересом к комплексной интерпретации данных нескольких методов при определении петрофизических и физико-химических свойств горных пород и внутрипластовых флюидов. Физикохимические свойства нефти определяются по данным комплекса методов диэлектрической спектроскопии, ЯМРрелаксометрии и геохимического анализа. Результаты этих методов дополняют друг друга, поскольку отличаются разной чувствительностью к определенным характеристикам породы и насыщающего ее флюида. Цель: совместная интерпретация данных методов диэлектрической спектроскопии и ЯМР-релаксометрии для определения группового состава и физико-химических свойств проб нефти, сопоставление с результатами геохимического анализа. Объекты: пробы нефти и конденсатов месторождений Восточной и Западной Сибири, характеризующиеся разными физикохимическими свойствами. Методы: лабораторные методы диэлектрической спектроскопии, направленной на определение комплексной диэлектрической проницаемости; ЯМР-релаксометрии, позволяющей оценить групповой состав исследуемого флюида; стандартные геохимические методы, включающие определение физико-химических свойств, фракционного и группового химического состава нефти. Результаты. Изучено 48 проб нефтей и конденсатов месторождений Восточной и Западной Сибири. Для 29 проб установлены значения: плотности при 20 °С, вязкости при 20 и 60 °С, содержания температурных фракций выше и ниже 200 °С, содержания метано-нафтеновых и нафтено-ароматических углеводородов, смол и асфальтенов. Экспериментально установлена зависимость диэлектрической проницаемости и времени поперечной релаксации от содержания разных групп углеводородных соединений, которая показала высокую чувствительность применяемых в работе методов к содержанию смолистоасфальтеновых соединений. Увеличение их доли в составе пробы нефти приводит к существенному уменьшению времен поперечной релаксации и значительному увеличению значений диэлектрической проницаемости. По ЯМР-данным был определен групповой состав проб нефти, который с точностью до 5 % при температуре 25 °С согласуется с результатами геохимического анализа. Поскольку времена поперечной релаксации ароматических соединений и насыщенных углеводородов сильно перекрываются, это не позволяет более детально установить граничные времена поперечной релаксации для каждой группы углеводородных соединений. The relevance of the research is caused by the increasing interest in an integrated interpretation of several methods data to determining the petrophysical and physical/chemical properties of rocks and intraformational fluids. The physical/chemical properties of oil are determined by a complex of data methods of dielectric spectroscopy, NMR relaxometry and geochemical analysis. The results of these methods are complemented each other, since they differ in different sensitivity to some characteristics of the rock and its saturating fluid. The main aim of the research is the sequential interpretation of dielectric spectroscopy and NMR relaxometry methods to determine the group composition and physical/chemical properties of oil samples, comparison of the obtained results with the results of geochemical analysis. Objects: oil and condensate samples from Eastern and Western Siberia deposits characterized by different physical/chemical properties. Methods: laboratory methods of dielectric spectroscopy aimed at determining the complex dielectric constant; NMR relaxometry which allows assessing the group analysis of studied fluid; standard geochemical methods including determination of physical/chemical properties, fractional and group chemical composition of oil. Results. 48 samples of oils and condensates from fields in Eastern and Western Siberia have been studied. The values were established for 29 samples: density at 20 °С, viscosity at 20 and 60 °С, content of temperature fractions above and below 200 °С, content of methanenaphthenic and naphthenic-aromatic hydrocarbons, resins and asphaltenes. The dependence of the dielectric constant and the transverse relaxation time on the content of different hydrocarbon compounds groups was experimentally established, which showed a high sensitivity of the methods used in this work to the content of resinous-asphaltene compounds. Increasing their proportion in the composition of an oil sample leads to a significant decrease in the transverse relaxation times and a significant increase in the values of the dielectric constant. The NMR data was used to determine the group composition of oil samples, which is consistent with the results of geochemical analysis with an accuracy of 5 % at a temperature of 25 °C. Since the transverse relaxation times of aromatic compounds and saturated hydrocarbons characterized by high overlap, this does not allow us to establish in more detail the boundary transverse relaxation times for each group of hydrocarbon compounds.
