scholarly journals Artifacts in metallography: dust.

The article discusses the identification of dust particles on the surface of metallographic samples. It is noted that the volume of literature on metallographic artifacts is very small one. This is due to the fact that the Russian – language literature of the metallographic direction was wtitten long ago when the structure was fixed using the photographic method on photographic plates or film. The complexity of the process and the lack of photographic materials excluded the generation of information about metallographic artifacts.Modern metallographic complexes capture structure images digitally. Therefore, in addition to images of the structure, it is possible to record sample preparation artifacts without restrictions. Dust particles on the surface of metallographic sections and their difference from non-metallic inclusions are illustrated. The use of dark-field illumination and polarized light to identify artifacts is considered. Some effects arising from metallographic etching are illustrated.

The proposed annual bibliography continues annotated lists of the Russian-language literature on glaciology that were regularly published in the past. It includes 277 references grouped into the atmospheric ice; 4) snow cover; 5) avalanches and glacial mudflows; 6) sea ice; 7) river and lake ice; 8) icings and ground ice; 9) the glaciers and ice caps; 10) palaeoglaciology. In addition to the works of the current year, some works of earlier years are added, that, for various reasons, were not included in previous bibliographies.

The article considers the main approaches to expanding international cultural and humanitarian cooperation, ensuring educational, scientific and informational interaction between the Russian Federation and European countries through international educational expeditions. These events were held in 9 European countries for leaders, teachers and learning organizations engaged in educational activities under the main and (or) additional general educational programs, media representatives of the countries running the events. The article was prepared on the results of work under the project Conducting international educational expeditions aimed at the Russian language, literature, culture and Russian education popularization, implemented by the LLC JV Sodruzhestvo with the support of the Ministry of Education of the Russian Federation. The article describes the formats of events proposed in the framework of the educational expeditions project, including the features of an integrated approach to their development and implementation, which allowed to ensure high interest of the target audience, easy and effective uptake of content presented for them.

Kurdish Studies, as an academic field, seems today to be dominated by English and Turkish-language literature. Little is known about the volume of literature that has been produced (and is available) in Russian, an important world language spoken across a vast geographic space in regions not far from Kurdish lands. In this review, we have explored this published literature by using searches in Google Scholar. We present the results of this inquiry, as a simple inventory which shall serve to acknowledge and highlight the Russian-language scholarship on the Kurds, Kurdish and Kurdistan. It shows that access to this scholarship is paramount if we want to arrive at a more global understanding of the issues related to the Kurds and Kurdish studies.

The study of acoustic signals from various representatives of insects, and in particular coleopterans, has a long history. In the Russian-language literature, systematic, faunistic and ecological studies on aquatic beetles, including those on the family Hydrophilidae, are widely known; however, studies on the bioacoustics of the coleopteran group are quite rare. The aim of our study was to study stress signals of two species of Hydrophilidae – Berosus frontifoveatus Kuwert, 1888 and Berosus spinosus Steven, 1808. The sounds of adults were recorded using a Behringer ECM8000 measuring condenser microphone. The sounds of B. spinosus males have a maximum frequency of occurrence in the range of 3729.31–4013.75 Hz, sounds of B. frontifoveatus is 4895.42–5842.76 Hz. The sounds of B. spinosus females have a maximum frequency of occurrence between 2585.98 and 2807.82 Hz. The sounds of B. frontifoveatus females have a maximum performance of the dominant frequency in the range of 2745.21–3476.23 Hz.

This article aims to determine the meaning of metaphor for revealing the metaphysical foundations of aesthetics, as well as to analyze the methods reflected in the philosophy of Kant, Husserl, Heidegger, Derrida, and Mamardashvili. Their works clarify the structure of the metaphysical metaphor and its aesthetic matrix. Since old times, the aesthetic thought viewed the concept of the language of metaphor with its dual ambiguity, various metaphorical figures as the structures internally connected with the categorical reflection on the system of art; and the metaphor itself was considered as the form of semantic perception and creation of the artistic landscape. Revealing the place of aesthetics within the structure of metaphysics, the author views the aesthetic role of the metaphorical within metaphysics, complexity of interrelation between the concept of metaphor and fundamental metaphysical category of existence. The world scientific literature features numerous works that view metaphor as a rhetorical figure. However, the research of metaphysical metaphor is rare. This article is first within the Russian-language literature to outline the approaches towards the aesthetic comprehension of metaphysical metaphor, as they are reflected in the philosophy of Heidegger and Derrida. They reveal intuition of the metaphor as metaphysics, describe the representation of metaphysical metaphor of light, interpret the transcendental ego as metaphor, and elucidate the concept of the substance of metaphor. Special attention is given to the aesthetic-metaphysical interpretations of metaphor in the modern Russian philosophy.

The optical effects which appeared on internal defects of optically transparent materials by use of various methods of optical staining, i. e. dark-field illumination and polarized light were researched. It was shown that methods of optical staining support to determine spherical defects under a surface of optically transparent materials. Formation of optical effects on materials defects in dark background are partially determined by design features of microscope objective and it was found out. It was defined that the investigation using polarized light the image formation of spherical defects occurs similar to uniaxial crystal.
