The organonickel complexes [Ni(Phbpy)X] (X = Br, OAc, CN) were obtained for the first time in a direct base-assisted arene C(sp2)–H cyclometalation reaction from the rather unreactive precursor materials NiX2 and HPhbpy (6-phenyl-2,2′-bipyridine) or from the versatile precursor [Ni(HPhbpy)Br2]2. Different from previously necessary C‒Br oxidative addition at Ni(0), an extended scan of reaction conditions allowed quantitative access to the title compound from Ni(II) on synthetically useful timescales through base-assisted C‒H activation in nonpolar media at elevated temperature. Optimisation of the reaction conditions (various bases, solvents, methods) identified 1:2 mixtures of acetate and carbonate as unrivalled synergetic base pairs in the optimum protocol that holds promise as a readily usable and easily tuneable access to a wide range of direct nickelation products. While for the base-assisted C‒H metalation of the noble metals Ru, Ir, Rh, or Pd, this acetate/carbonate method has been established for a few years, our study represents the leap into the world of the base metals of the 3d series.

Purpose. The aim of the study is to characterize the image of the snake as a chthonic creature in Khakass culture. Based on the goal, the following tasks were set: to analyze folklore and ethnographic information of these people and identify the key components of this mythological creature, to discover the semantic connections of its image with natural objects and elements, as well as with the idea of death. The work is based on the analysis of a wide range of sources. For the first time, it introduces field ethnographic and archival folklore materials, as well as author translations from Khakas into Russian of excerpts from heroic legends – alyptyg nymykhtar, proverbs and sayings related to the topic under consideration. Particular attention is paid to the lexical analysis of the myth-ritual complex related to the image of the snake. Results. As a result of the analysis, the following conclusions can be drawn: 1) the image of a snake was widespread in Khakass culture. This reptile was endowed with sacred attributes. In this connection, its image was widely used in language, folklore, and ritual practice; 2) the formation of characteristic features of the mythological image of this reptile was influenced by its biological nature, first of all, the morphology of its body, behavior, lifestyle, way of hunting, and, of course – the environment; 3) with all the variety of symbolic characteristics of this reptile, the key is its perception, as a chthonic creature. It was closely associated with the cult of natural objects, in particular with respect for the land. Its deep connection with the underworld is revealed; 4) in religious and mythological consciousness of the Khakass, this reptile acts as an inhabitant of the world of the dead, and is also a harbinger of death, and often its personification; 5) in mythological consciousness, the projection of its zoological features was expressed mainly in endowing its image with features such as agility, cunningness and greed, which was reflected in phraseological units.

For the first time in the Russian historical and philosophical literature, the monograph attempts to comprehensively consider the philosophical views of the great playwright and thinker. Shakespeare is presented as a philosopher who considered in his masterpieces the relation of man to the world through a series of"borderline situations". Shakespeare not only anticipated the existentialist philosophers, but also appeared in his work as the greatest philosopher-anthropologist. He reflects on the essence of nature, space and time only in close connection with thoughts about human life. For a wide range of readers interested in the history of philosophy and Shakespeare studies.

AbstractA case was reported of a fetus with the anomaly of limb body wall complex associated with placenta accreta. To date, only one account of this condition has been published in the world literature. Due to the low frequency of both complications, the hypothesis has been raised that this association may have happened not by mere coincidence, but rather by a possible common etiopathogenic mechanism. For the first time, a study proposes the existence of a possible etiopathogenic connection between the anomaly of limb body wall complex and hypoxic disorders caused by inadequate placentation in previous uterine scarring.

Abstract From the economical point of view, the genus Ganoderma is one of the most important groups of Basidiomycetes due to their medicinal effects and also because they cause decay in a very wide range of tree species all over the world. In this study new data of the Hungarian Ganoderma species are published and the specimens in accessible Hungarian herbarium collections are processed and revised. The article includes the nomenclatural status, the morphological characters, the host preference, frequencies and the details of the fungarium samples of six Ganoderma species (Ganoderma adspersum, G. applanatum, G. carnosum, G. cupreolaccatum, G. lucidum, G. resinaceum) as well. In total 215 Ganoderma specimens are examined and 10 hosts of the six native Ganoderma species new for Hungary are presented. The Hungarian locality and time of the collection of the only Ganoderma carnosum (IZ3122) specimen and two new localities of this rare species is published here for the first time.

Objective of the article: to consider sports neologisms as a means of objectifying the universal in the German language world picture. The introduction provides a definition of sports neologisms. This paper analyzes them based on data from the portal of the German language Institute in Mannheim www.owid.de. The novelty of the research is that for the first time the universal in the German language picture of the world is represented by sports neologisms that have great research potential and practical significance for a wide range of people interested in sports problems. The methodological basis of this research is primarily the cognitive approach as the main one and the semasiological approach as the accompanying one. The relevance of the research is due to the wide spread of sports in all countries of the world, which means the appearance in recent years of works that consider sports lexemes on the material of various languages. Results: the analysis of German sports neologisms showed that the vast majority of lexemes are words of English origin, which indicates the lexical way of combining different cultures. Sports neologisms that have emerged based on existing word-formation models in German or by reinterpreting existing lexemes also do not reflect the national mentality in the nominative system of the native language. Prospects for further study of German sports neologisms in various aspects: typological, metalanguage, and normative are offered.
