Детальное изучение процесса изменения состава шахтных вод выполнено с помощью оригинальной технологии классификации многомерных наблюдений АГАТ-2. Обнаружено четыре главных направления изменения состава вод. После завершения ликвидации угольных шахт резко усилились процессы окисления и образования сульфатных вод первого направления, снизилось образование вод второго направления, полностью отсутствуют воды третьего направления, ослаблено четвертое направление. Происходит формирование мощных потоков загрязнения и возникает необходимость мероприятий по реабилитации окружающей среды в Восточном Донбассе. Выполнен пространственный анализ распределения состава шахтных вод на территории региона. A detailed study of the process of transformation of the whole mine water using computer technology classification of multivariate observations AGAT-2. Found the four main directions of changes in the composition of the waters. After completing the Elimination of coal mines have dramatically increased oxidation processes and formation of sulphate waters first destinations, decreased water education second, completely absent of water the third, diminished fourth direction. Is the formation of powerful streams of pollution and there is a need for environmental rehabilitation activities in the region of environment. Completed spatial analysis of distribution of composition of mine waters in the Eastern Donbass.

The regularities in forming chemical composition of mine and surface waters in the Eastern Donbass were studied using the techniques of statistical estimation of component concentration distributions, the methods of assessing environment pollution, and the digital computer technology on multidimensional classification observations AGAT-2. The article shows that the mine water in the Eastern Donbass is a powerful source of polluting environment, causing serious ecological damage to the territory. Coal mine water contain a lot of dissolved substances up to 413 thousand t/year, among which macro components and various metals forming a significant part. The mean concentrations of most components in mine water hundreds times exceed the maximum allowable concentrations (MACs), and they exceed the maximum concentrations in thousands times. The surface water quality was analyzed in the region proceeding from the results of testing small rivers and streams. Using classification technologies, five genetic variants of surface waters were identified by the macrocomponents. The first option characterizes the initial phase of surface water formation outside the pollution impact. Other options reflect the growing degree of water pollution in the region. The distribution of genetic water variants was shown throughout the region. The calculation of surface water pollution by 20 components revealed the cumulative indicator of pollution to be equal to 108 corresponding to the emergency crisis category. About 65% components exceed MAC. Surface water classes uniform in the content of 15 metals were distinguished using the digital computer technology AGAT-2. A cumulative indicator of pollution varies from 27 to 65, which corresponds to a tense and emergency crisis situations. Therefore, mine waters pollute significantly the surface waters in the Eastern Donbass. Conclusion is made about the need for rehabilitation measures in order to improve the quality of surface waters in the region.

The article presents the generalized results of chemical composition research of waters from Inhulets and Saksahan rivers on the territory adjacent to the Northern and Inhulets with pumping of underground waters (mine and quarry), which have an abnormal chemical composition, high mineralization and contain high concentrations of microcomponents. The following scheme of mine water utilization is used in the Kryvyi Rih iron ore basin: the mines of the northern part of Kryvbas discharge water into the tailings dam of Northern Iron Ore Dressing works (Northern GZK); mines of the southern part discharge mine waters into the storage pond of the Svistunov creek during the year, and in the winter its waters are discharged into the Inhulets River with subsequent washing of the river in the spring-summer period. Such treatment of mine and quarry waters has led to the formation of a hydrochemical anomaly on the territory of Northern GZK with the center in the tailings. The mineralization of water in the pond reaches 23 g / l (2020). There is a high content of microcomponents: lead, cadmium, vanadium, manganese, boron, bromine, nickel, mercury, thiocyanates. As a result, the mineralization of the Saksahan River water increases over time (up to 5.4 g / l), the content of microcomponents also increases and becomes quite high. Prolonged use of the Inhulets River for utilization of mine water from the Svistunov creek storage pond has led to a change in the type of water: instead of type II (river water), Inhulets water belongs to the type III (metamorphosed waters). There are no regularities in the change of chemical composition of water (hydrochemical regime) in Inhulets, which is a consequence of the introduction of the scheme "discharge – flushing" for the disposal of mine water. Among the microcomponents in the water of Inhulets there is an increased content of vanadium, boron and bromine (7–8 times), single excess of lead content. The analysis of equilibria in the carbonate-calcium system of the Inhulets and Saksahan rivers confirmed that the existing hydrochemical regime for the studied rivers is stationary, thus, the environmental measures implemented will not have rapid consequences.

The article raises the problem of classification of the concepts of computer science and informatics studied at secondary school. The efficiency of creation of techniques of training of pupils in these concepts depends on its solution. The author proposes to consider classifications of the concepts of school informatics from four positions: on the cross-subject basis, the content lines of the educational subject "Informatics", the logical and structural interrelations and interactions of the studied concepts, the etymology of foreign-language and translated words in the definition of the concepts of informatics. As a result of the first classification general and special concepts are allocated; the second classification — inter-content and intra-content concepts; the third classification — stable (steady), expanding, key and auxiliary concepts; the fourth classification — concepts-nouns, conceptsverbs, concepts-adjectives and concepts — combinations of parts of speech.

Date of «birth» of phytosociology (phytocenology) is considered to be 1910, when at the third International Botanical Congress in Brussels adopted the definition of plant association in the wording Including Flaó and K. Schröter (Flahault, Schröter, 1910; Alexandrov, 1969). The centenary of this momentous event in the history of phytocenology devoted to the 46th edition of the Yearbook «Braun-Blanquetia», which began to emerge in 1984 in Camerino (Italy) and it has a task to publish large geobotanical works. During the years of the publication of the Yearbook on its pages were published twice work of the Russian scientists — «The steppes of Mongolia» (Z. V. Karamysheva, V. N. Khramtsov. Vol. 17. 1995), and «Classification of continental hemiboreal forests of Northern Asia» (N. B. Ermakov in collaboration with English colleagues and J. Dring, J. Rodwell. Vol. 28. 2000).

In the first part of his article, the author examines the current state of the issue of secondary dementia and proves that a group of psychoses, known under the name secondary dementia, should be left in the classification of mental illnesses. The second part is devoted to the analysis of Krpelin's scholarship on dementia praecox, and the author fundamentally disagrees with many of the provisions of the latter. In the third part, the ethiology, clinical course and recognition of premature dementia are analyzed.

The aim of the study is to describe the titles of Latvian metal music albums, from the perspective of content, by identifying the common and distinctive character of the metallic music tradition, and perhaps even the local one. Of 241 album titles (data on Dec. 31, 2019), most are in English, some in French, Latin, Russian, some consisting of digits, and 69 titles in Latvian. These titles are the subject of the research. The main source is Encyclopaedia Metallum (www.metal-archives.com), which still does not reflect the current situation concerning Latvian metal music. Album titles in this study are viewed separately from album designs and song titles and are analysed from the perspective of content. The album title is an important part of the work that has been issued because it is an element that makes the audience/buyer pay attention to the album because it must not be forgotten that today the album is also an item that you want to sell. In general, it can be concluded that Latvian metal musicians, with their album titles in Latvian, are mostly following world trends, as evidenced by the integration in the researcher Deena Weinstein’s classification of Dionysian discourse and discourse on chaos. Most titles are more relevant to the discourse on chaos because the thematic circle of chaos is wider. Latvian mythology, along with history, is an up-to-date source for the creative work of bands that is responsible for the local feeling of the titles. A large enough number are titles that are difficult to fit in the Weinstein’s division and form the third group with philosophical titles and simply all sorts of titles. If the philosophical titles follow the world’s trends, the simple titles include the names of the events, tributes, and the titles of literary works, which give them a local character.

Folklore among the Au of Papua New Guinea takes three forms: Tipiitim Tipiir, tales told the ancestors by the spirits; Tipiitim Herwe, tales invented by the ancestors; and Him, tales invented by the older men. The first are basically etiological, the second provide emotional release and entertainment, and the third show attempts to cope with the cultural flux which followed the arrival of Europeans. Certain Scriptural parallels are explored, with their implications for crosscultural communication of the gospel.


The effect of various dosages of the extract of the thyme medicinal plant on the slaughter qualities and the chemical composition of the meat of broiler chickens has been studied. The preparation was obtained by the method of water-ethanol extraction followed by low-temperature drying at the Agroecologia research laboratory of the Kuzbass State Agricultural Academy. The scientific economic experiment with the duration of 40 days was performed with broiler chickens of the Hubbard ISA F 15 cross at the broiler farm. One reference and five experimental groups of day-old broiler chickens were formed, 37 chickens in each group. The chickens in the reference group received basic diet, while the broilers in the experimental groups additionally received thyme extract in the following daily dosages: the first — 2 mg/kg, the second — 4 mg/kg, the third — 6 mg/kg, the fourth — 8 mg/kg, and the fifth — 10 mg/kg of body weight. At the end of the studies, the positive effect of feeding thyme extract on the characteristics of anatomical dissection of broiler chickens' carcasses was found. In the third, the fourth, and the fifth experimental groups, no significant differences were found, compared to the reference group. By the results of dispersion analysis of the data, a significant effect of thyme extract on the contents of lysine, threonine, and methionine has been found by the amino acid composition of the meat of broiler chickens.
