Żelazo meteorytowe w starożytnym Egipcie przed okresem późnym

The aim of the article is to present an unusual raw material, which is the meteorite iron and its specific status in the culture of ancient Egypt. The presentation of this extraordinary material, highlighting the features allowing to recognize it, the interpretation of the artifacts made of it (taking into account the physicochemical analyzes), and the development of the results of experimental works recreating the methods of its processing allow us to obtain the necessary information about the delineation of meteorite iron metallurgy in ancient Egypt up to the beginning of the Late Period. An important source for achieving the article’s goal are also texts. Text analysis highlights the ambiguity of the terminology used to describe meteorite iron. By reviewing the contexts of its use, they allow us to enrich knowledge about its metallurgy and help to characterize the status of this metal in the consciousness of the Egyptians.

Histological Feature of Uterus and Uterine Tube During Late Period of Pregnancy in Rabbits

Current work was conducted to investigate the histological architecture of the uterine tube and uterus during the period of late pregnancy in rabbits. Twelve adult local breed rabbits were used. The samples from different parts of the uterine tube were prepared for histological study after staining with H&E, Masson’s trichrome and combine Alcian blue (pH2.5)-PAS. The pre ampulla was a narrow tube and its tunica mucosa had slightly long simple mucosal folds lined by pseudostratified columnar epithelium, the ampulla had a wide lumen and its tunica mucosa displayed several highly tall branched mucosal folds with few short simple folds while the isthmus was the narrowest region and its tunica mucosa displayed few of tall and short simple mucosal folds. The mucosa of three parts of the uterine tube was lined by pseudostratified columnar epithelium which is composed of three types of cells: mucous secretory cells, non-secretory cells and basal cells, the mucous secretory cells were the predominant type and revealed secretory activities. The lamina propria-submucosa of the uterine tube was composed of cellular connective tissue and tunica muscularis. The uterus had a very thick wall with well-recognized endometrium and myometrium, the endometrium was composed of many-branched and simple endometrial folds that were covered by multinucleated syncytial cells and simple cuboidal epithelial cells. Lamina propria was composed of loose connective tissue had scattered groups of well growing simple uterine glands that showed secretory activities. The current result showed that the uterus during the late period of pregnancy was differed from those of non-pregnant rabbits, while the uterine tube at late pregnancy has a structure that appeared prepared for the next physiological period.

Morphfological changes in the membranes of the trachea of guinea pigs in experimental ovalbumin-induced allergic inflammation of the airways.

Background. In recent years, there has been an increase in the number of allergic diseases of the respiratory organs, especially in children. The predictor of the further development of bronchial asthma is sensitizing at an early age to the allergens of chicken egg. The use of new knowledge about the allergenic components of the chicken egg will predict the risks and clinical features of the disease. Despite the importance, the problem of morphogenesis of allergic inflammation of the wall of the trachea is not sufficiently studied, so far many issues are not found in morphology and require further research. Objective.The aim of the study is to establish morphological changes in the tracheal membranes in experimental ovalbumin-induced allergic inflammation of the airways of guinea pigs. Methods. The thickness of tracheal wall of 48 male guinea pigs was investigated by histological, morphometric, statistical methods on the twenty-third, thirty-sixth, thirty-sixth and forty-fourth days after the initiation of the experimental ovalbumin-induced allergic inflammation of the airways. Results. We have found, that maximum statistically significant thickening is shown in the late period of tracheal mucosa in 2 times on the 44th day of observation and tracheal submucosa in the 3rd experimental group on the 36th day of observation (increasing coefficient 2) compared to the control. However, the thinning of tracheal submucosa is observed in the early period of the inflammatory process on the 23rd and 30th day of observation. It has been proved, that the allergic inflammation of the tissues of the trachea caused by the sensitization and allergization of ovalbumin leads to the change in the thickness of layers of trachea in the chronobiological aspect. Conclusion. On the 23rd and 30th days of the experiment, thinning of tracheal mucosais observed due to damage of epithelial cells. Thickening of tracheal mucosa and submucosa was found in the third and fourth groups of observation (late period of allergic inflammation) compared with animals of the intact group and the control group due to an increase in the area of loose connective tissue, which is a consequence of the continuation of the allergic inflammatory process in the trachea after the end of the experiment.

Une paratextualité émergente dans les tombes privées

In this paper, I investigate the speech captions (the so-called ‘Reden und Rufe’) in the private tombs from the Old Kingdom to the Late Period. I aim to show some of the ways used by the Egyptian scribes and/or artists to formally distinguish these speeches from other captions and inscriptions displayed in private tombs. After presenting the text- image interrelation and the most common speech caption layouts, I turn my attention to the form(s) of these captions and trace back the appearance of discursive marks in Old Kingdom mastaba as first evidence of paratextuality. I then offer a diachronic overview of the other paratextual means used to categorize a caption as a speech or a song: Dd-formulas, the parenthetic in indicating a direct quotation as well as the expression xn n wSb and xn n nhm.

Vascular-tissue relations in the lungs in experimental superinvasive opisthorchiasis

Structural changes in the lungs in superinvasive opisthorchiasis at various stages of invasion were studied. The morphology of permanent epithelial proliferation at the initial stage and their decrease in the late period were revealed. With the formation of granulomas in the interstitial tissue of the respiratory organs, with changes in the chronic period towards the formation of sclerotic foci. Key words: superinvasive opisthorchiasis (CO), metacercariae, acinus, terminal bronchioles (TB), cell infiltrates, pneumocytes.

Political Implications of Philosophical Parrhesia in Michel Foucault’s Late Lectures: Genealogy of Critique and Reality of Philosophy

The concept of parrhesia (free, true and courageous speech) is central to Michel Foucault’s last lecture courses. In this “late” period of his scientific career, the French philosopher started a thorough analysis of the ancient and early Christian sources with the aim to construct a detailed genealogy of the two phenomena that played a crucial role in the Western history — the genealogy of subjectivity and the genealogy of the “critical tradition” in philosophy. In order to analyze the latter, during the lecture course “The Government of Self and Others” (1982—1983), Foucault turned to the texts of Plato, which he considered foundational for the philosophical practices of veridiction in the West. The Platonic paradigm presents philosophy with a number of fundamental tasks, the main of which is the task of constantly testing the reality and seriousness — testing the words (logos) through the deeds and practices (ergon). Foucault postulates that in the modern philosophy this test invariably results in a certain attitude towards politics and power, which assumes rejection of the direct participation in political affairs, constant criticism of our mistakes and misconceptions, the search for and revelation of ways, in which we, as subjects, are able to change ourselves. In this article, the authors attempt to shed light on the genealogical significance of Foucault’s concept of parrhesia and its relationship to the modern philosophy; present the classification of parrhesia (on the basis of Foucault’s lectures) that allows to identify political and philosophical dimensions of this phenomenon and their different modalities, as well as review in a holistic way the Platonic philosophical parrhesia and consider the problem of its complex relationship with politics, which becomes especially acute when the “reality of philosophy” is being tested.

Zlata Tkach’s Concerto for Piano and Orchestra as a Culmination of the Composer Symphonic Thinking

The purpose of the article is to characterize Zlata Tkach’s Piano Concerto as the culminating composition in the genre of the composer’s symphonic music. The research methodology is based on the method of complex musicological analysis, due to which, the role of this work in the system of memorial genres of the author is determined, typical style features of her work late period are revealed, the thematic structure of the Concerto is characterized from the position of the manifestation of the principle of dialogicity and monothematism. The scientific novelty of the research is that for the first time, intonation processes in a Piano Concerto by Z. Tkach are systematically analyzed and the correlation of its traditional and innovative features is characterized. Being by genre attribution an opus with a pronounced desire to use modern means of expression, the concert is distinguished by the manifestation of the principle of microthematism and textural thematism. In the dramaturgical solution, the author conducts a constructive search in dynamic, timbre and rhythmic comparisons. At the same time, the intonational unity between the sections of the form, being the development of the romantic principle of poetry, is expressed in the form of monothematism. Conclusions. The creative method of Z. Tkach manifests itself in the synthesis of tradition and experiment. This is confirmed by the intonation-thematic structure of the Piano Concerto, in which the convergence of contrasting material contributes to the formation of an integral musical and dramatic concept. The motifs that form the basis of the monothematism complex establish intonation arches between the sections of a one-part composition, fastening them and subordinating them to a common plan. Important importance belongs to the opposition of the roles of the participants in the performance. Their dialogical activity is manifested in a peculiar way by the composer, primarily in the dialogue between the soloist and the orchestra: the interweaving of two contrasting figurative spheres is realized primarily in terms of content. The principle of monothematism is manifested especially vividly in the characterization of tragic reflections, painful reflections on the eternal conflict of the creative personality with the surrounding world, leading to a deep understanding of what exists. The other embodies the dynamism of life, dominating in the culmination of ‘action’, the accumulation of energy. Both the piano and the orchestra are equally involved in the development of both figurative principles. The resulting translational, purposeful movement towards the finale determines, along with the principle of monothematism, the integrity of the entire composition.

A New Interpretation of the Grid System Reform in the Late Period

This paper offers a new art-historical interpretation of the grid reform of anthropomorphic representations in Egypt around the mid-seventh century BC. The objective of this paper is two-fold. First, it will demonstrate the problems with previous interpretations, which depended, on the one hand, upon the written record of Diodorus Siculus regarding the Egyptian method of statue production, and upon comparative analyses of the two-dimensional representation of human figures on the other. Secondly, this paper is devoted to providing a new understanding of the art-historical context of the grid reform. This reform – in which Late Period Egyptians abandoned the tradition that had been utilised for nearly 1,800 years and created a completely new system by uniting the Egyptian metrological system and the traditional method of grid projection – less reflects improvement in the appearance of the image, and rather demonstrates a metaphysical development that had never been seen or experienced before.
