Studies of the processes of natural renewal of Crimean pine, carried out during 2018–2019, on the mountain ranges of the Yalta Mountain Forest Reserve allowed us to establish a number of the following features. The surge of renewal is transient in time and the basis of the coenopopulations of undergrowth at the object of research is made up of plants that appeared in the first two post-fire years. Individuals that appeared in subsequent years occupy vacant places in the conditions of existing renewal niches, complementing the structure of the age spectra of pine undergrowth, emphasizing the asymmetry of the spectral distribution series. On the one hand, the spatial structure of undergrowth coenopopulations is a representation of the “matrix” of forest fire, on the other hand, it is determined by the structure of pine trees’ fruiting. The monotonous decrease in the density of the population field of undergrowth, due to the remoteness of the walls of the mother plantings and the specifics of seed dispersal, is supplemented by the alternation of undergrowth biogroups of increased density. The presence of areas of increased density against the background of constantly decreasing density of plants with a distance from the walls of the mother plant is predetermined by the influence of testes and seed curtains preserved during the fire. At each specific point in the renewal space, the structure of the process or its shape will be determined by the influence of external environmental and internal endogenous factors due to the biogroup effect of plant groupings. Polyvariance of the spatio-age structure of the undergrowth in the gorelnik space is the result of autoregulation of the cenopopulation structure in accordance with the capacity of the existing renewal niches.

Рассматриваются древние и средневековые письменные источни- ки, в которых отражаются взаимоотношения народов Кавказа, а именно грузин и осетин, с одной стороны, осетин и абхазов – с другой. За многие века в их отно- шениях были периоды не только дружбы и взаимопонимания, но также времена- ми напряженность в силу различных объективных и субъективных причин. Автор пытается анализировать их с учетом возможностей журнальной статьи. The article considers ancient and medieval written sources, which refl ect the relationship between the peoples of the Caucasus, namely the Georgians and Ossetians, on the one hand, and the Ossetians and Abkhazians, on the other. For many centuries, in their relationship there were periods of not only friendship and mutual understanding, but also at times tension due to various objective and subjective reasons. The author tries to analyze them taking into account the possibilities of the journal article.

AbstractThe effects of the addition of mixed cations, i.e. Na+/Cs+, Ba2+/Cs+, and Ba2+/Zn2+, to the acid form sulfonated styrene copolymers on their dynamic mechanical properties and morphology were investigated. It was found that the matrix glass transition temperatures did not change with the ratio of the one cation to the other. As expected, however, the ratio of one cation to the other in the mixed cations affected cluster glass transition temperatures significantly. It was also found that the activation energies for the glass transitions for the matrix phase remained constant, while those for the cluster phase changed with the ratio of the two cations. In addition, the position of the SAXS peak was found to be affected by the type of cations. From the results obtained above, the decrease in the cluster Tg with increasing the amount of cesium and zinc cations in Na/Cs, Ba/ Cs, and Ba/Zn mixtures, were explained on the basis of the considerations of the size, charge, and type of cations, which alter the degree of clustering as well as ion-hopping mechanism.

This article describes a direct approach for computing scalar and matrix kernels, respectively for the unitary ensembles on the one hand and the orthogonal and symplectic ensembles on the other hand, leading to correlation functions and gap probabilities. In the classical orthogonal polynomials (Hermite, Laguerre, and Jacobi), the matrix kernels for the orthogonal and symplectic ensemble are expressed in terms of the scalar kernel for the unitary case, using the relation between the classical orthogonal polynomials going with the unitary ensembles and the skew-orthogonal polynomials going with the orthogonal and symplectic ensembles. The article states the fundamental theorem relating the orthonormal and skew-orthonormal polynomials that enter into the Christoffel-Darboux kernels

This paper is an exploration of similarities and differences concerning absolute constructions in French, German and Norwegian. In the first part, I have examined a more general question raised by these constructions: the connections between these types of absolute constructions and the matrix subject. I have shown that the means by which the absolute constructions are related to the subject can be morphosyntactic, semantic and pragmatic. The second part contains a purely contrastive analysis. Two issues have been examined: on the one hand, the absolute constructions and their congruent and non-congruent correspondences, on the other, the use of determiners. Essentially, French is different from the two Germanic languages, but similarities also exist between French and German, which are the center of a European Sprachbund.

Throughout the entire literary oeuvre of Miroslav Krleža we are faced with a great number of credible descriptions, describing real historic events, or real artists and artworks belonging to the rich resources of European art history. By applying a cryptographic method of incorporating descriptions into his texts, Krleža on the one hand hid his sources, while on the other also revealed them. He hid them in the tissue of fictional texts, and unmasked them using a key work only those familiar with the source could identify. We term this method the use of “belletristic cryptograms”, and can further categorise it into thematic subgroups of concealed artwork descriptions, naming this whole method the use of hidden ekphrasis. The choice of artworks Krleža describes in his work is comprehensive, diverse and each described differently. Since we are dealing with literary texts, descriptions are often used in the function of a wide array of interpretative strategies of depiction; in some aspects, they are used as a mere glimpse into a piece of art with the goal of visually associating, evoking or minutely symbolizing the incorporeal frame of an artist’s mind or of the wider social context. In other aspects, the artworks are richly and meticulously presented with regard to their importance and credibility as they, according to Krleža, possess an “ethical intelligence” and “ethical conscience”. Only Krleža’s prose is researched here, and this is done on two levels. We take a look at examples where real art is incorporated into fictional texts in order to determine the significance and meaning of a certain dialogue, mise-en-scène or situation. This is most commonly found in the author’s plays, novels and novellas. On the other hand, we can trace a completely opposite method by which artworks enter these texts, where, due to their historic determination and already established worth/status, they thus re-enter reality, as seen from the perspective of Krleža’s life and work, so as to yet again test art history’s credibility through the matrix of contemporaneity. This approach is most often found in Krleža’s essays, critiques and diary entries.

In the first decades of the XIX century. the territory of the Russian Empire from Western Europe is beginning to penetrate chiliastic ideas. The term "chiliism" refers to the well-known doctrine of the millennial kingdom of Icyca Christ on earth, dating to the first centuries of Christianity. The ideas of chilias became especially popular during the reign of Alexander I, who himself was sympathetic to the mystical-chiliatic teachings. Chilias in the Russian Empire spread in two ways. On the one hand, chiliastic ideas penetrated with the works of German mystics of the late eighteenth - early twentieth centuries. On the other hand, in anticipation of the fast approaching of the millennial kingdom of Christ, the German cultists of the Hiliists moved large parties across southern Russia to the Caucasus, thereby facilitating the spread of their ideas. The religious formations of the Orthodox sectarianism of the chiliastic-eschatological orientation are represented by the Jehovah-Hlinists ("Right Brotherhood"), the Ioannites, and the Malavans.

The purpose of this article is to introduce Czech immigrants’ dialects still spoken in several villages in Krasnodar Krai, Adygea and Omsk Oblast of Russia. These dialects appeared as a result of different waves of Czech rural migration in the latter half of the 19th and at the start of the 20th century respectively. The author analyzes the main features of the named varieties, focusing on those that indicate the dialects’ origin, on the one hand, and those that have been affected by their long-term contact with the dominant Russian language, on the other.

Stiegler argued in Cinematic Time and the Question of Malaise (the third volume of Technics and Time) that we must refer to archi-cinema just as Derrida spoke of archi-writing. In this article he proposes that in principle the dream is the primordial form of this archi-cinema. The archi-cinema of consciousness, of which dreams would be the matrix as archi-cinema of the unconscious, is the projection resulting from the play between what Husserl called, on the one hand, primary and secondary retentions, and what Stiegler, on the other hand, calls tertiary retentions, which are the hypomnesic traces (that is, the mnemo-technical traces) of conscious and unconscious life. There is archi-cinema to the extent that for any noetic act – for example, in an act of perception – consciousness projects its object. This projection is a montage, of which tertiary (hypomnesic) retentions form the fabric, as well as constituting both the supports and the cutting room. This indicates that archi-cinema has a history, a history conditioned by the history of tertiary retentions. It also means that there is an organology of dreams.

Автор ставил перед собой троякую задачу. Во-первых, определить реальный информационный потенциал европейских сочинений XVIII века как источника исторических знаний о Кавказе. Во-вторых, привлечь внимание исследователей к изучению соотношения между источниковедческой и историографической ценностью этой литературы в контексте процесса зарождения научного кавказоведения. В-третьих, выявить роль приходящих политико-идеологических факторов, обусловленных геополитическими интересами западных государств и их специфическим (так сказать, ориенталистским) восприятием Востока вообще и Кавказа в частности. Авторские выводы требуют дальнейшей проверки с целью подтверждения одних идей, корректировки других и критического переосмысления третьих. The threefold task the author had in mind implies the following. First, to assess informative value of the 18th century European sketches on the Caucasus as a source of the appropriate knowledge. Second, to redirect scholarly attention towards searching for distinct lines between murky facts and their interpretation, oftentimes arbitrary, uncritical, and even openly biased. It would help to reveal what might be called a scientific trend in Western «historiography» on the region`s past. Third, to expose the role of the incoming political and ideological factors determined by geostrategic interests of the concerned States on the one hand and by its largely prejudiced, as it were, orientalistic perception of the East on the other. While the author found his general approach promising he hesitates to claim that all of his conclusions are flawless. Some of them need further arguments either pro or contra to deservedly place the subject in question in a wider context of history.


Mites of the family Erythraeidae Robineau-Desvoidy, 1828 are distributed worldwide and have been reported as natural enemies of sucking pests. Adults and deutonymphs are predators; larvae of most species are ectoparasites of different arthropods. They can be harmful to beekeeping. Some species cause dermatitis in humans. Erythraeidae of the Caucasus are poorly studied. This article is the first report on mites of the genus Erythraeus Latreille, 1806 of the family Erythraeidae living in Azerbaijan. An annotated list of five species of mites of this genus collected in the Greater Caucasus is provided: Erythraeus phalangoides (De Geer, 1778), E. regalis (C.L.Koch, 1837), E. gorcensis Gabrys, 2016, E. opilionoides (C.L.Koch, 1837), E. adpendiculatus (Schrank, 1781). All of them are recorded from Azerbaijan for the first time. An identification key to imago of the Erythraeus species is given. The original photographs of imago were taken to clarify the determination. Mites were collected in three landscape zones: semi-desert (4 species), mountain-steppe (2 species) and mountain-forest (2 species). The Absheron Peninsula (semi-desert) is studied best; four Erythraeus species were found there. Most of the species were collected in artificial forests with a predominance of Eldar pine (4 species, 12 individuals). In other biotopes, mites of the genus Erythraeus are rare: 2 species (3 individuals) were found in broad-leaved forests of the low mountains, 1 species (1 individual) in a forb steppe, 1 species (1 individual) in an arid open woodland consisted of weeping pear trees, 1 species (1 individual) in a garden. Only four individuals of E. regalis were recorded on plants. The other mites were collected under stones, which will make it possible to attribute them to herpetobionts, and E. regalis to herpeto-hortobionts. Out of 18 individuals found, 17 were adult, and one larva of E. regalis was removed from spittlebug on a blackberry. The most common Erythraeidae genus in the Greater Caucasus is Abrolophus Berlese, 1891 (39 individuals belonging to eight species were collected). This is the only genus of the family Erythraeidae, found in four landscape zones, from semi-desert to subalpine. The genus Erythraeus was not found in the subalpine zone.
