In the article presented results of researches on the change of parameters of physical and chemical properties and nutrition elements in chernozem typical for influences minimizing soil cultivation and application of various fertilizer systems. Improvement of physical and chemical properties of chernozem typical under the influence of fertilization was established, although the introduction of straw, green manure and mineral fertilizers in the plow contributed not to a critical increase in hydrolytic acidity. The highest capacity of easily hydrolyzed nitrogen compounds, mobile phosphates and exchangeable potassium are obtained for the use of straw, green manure and mineral fertilizers. Methods of soil cultivation did not have a significant effect on the nitrogen regime of the soil. Minimization of cultivation is an effective way to improve the phosphorus and potassium regime of typical chernozem for growing crops.

В статье анализируется исторический нарратив Джоффри Китинга (1580-1644) «Основа знаний об Ирландии» как рефлексия по поводу британского композитарного проекта в Ирландии. В центре внимания образ власти, сконструированный не только на основании позаимствованного ирландского средневекового материала, но и современных Китингу представлений. Можно заключить, что нарратив Китинга вобрал в себя концепты власти, перешедшие в нетронутом виде из предшествующей ирландской традиции, а также анахронизмы, элементы современной Китингу реальности, наложенные на прошлое Ирландии.

The aim of the work was the development and testing of a method for determining the dynamic modulus of elasticity of running-in sealing gasket coatings for GTE turbines. Many contradictory requirements are put forward to these coatings, therefore, to satisfy them, it was proposed to apply coatings with variable properties at various stages of the life cycle of gas turbine engines. However, the development of new coatings requires a variety of mechanical tests, including to evaluate the dynamic modulus of elasticity. The porous structure and, accordingly, the low strength of the developed coatings do not allow the use of standard methods for the evaluation of mechanical properties, so there is a need to develop a special method for determining the elastic modulus. In the course of the study, the finite element method, statistical methods, experimental methods for determining the natural frequency of oscillations were applied. Investigations were carried out for running-in sealing coa...

The article is devoted to the examination of evidence about Schema-hieromonk Theodosius (Kharitonov; 1869–1937), in the period under consideration — Hieromonk Theo- fan, during his service as an inspector at the Vologda Theological Seminary (1897–1901). Sche- ma-hieromonk Theodosius, also called Karulsky (after the place of his exploits), was one of the most famous ascetics and confessors of Russian Athos in the early 20th century. Coming from peasants of Saratov province, he received higher spiritual education in Kazan Theological Academy and served first in the Tauride and then in Vologda Theological seminaries. After leaving the seminary, he spent the rest of life on Mount Athos, standing out for his meekness, prayerfulness and ascetic deeds even by the standards of the Holy Mountain. Father Theodosius was also distinguished by his theological knowledge, a really exceptional case with peasant pop- ulation of the Russian Athonite monasteries: he had to speak on all topical issues — the transi- tion to a new calendar, onomatodoxy, the “catechism” of Metropolitan Anthony (Khrapovitsky); his opinion was taken into account not only in Russian, but also in Greek monasteries. Prayer Diary and Biography of Fr. Theodosius were published in the 2000s. However, the bio graphers of the ascetic had very little information about his life before moving to Athos. This article summarizes a series of publications aimed at clarification of his biography during the Russian period. The immediate task of examining various contemporary testimonies re- quired significant preparatory work. The researcher managed to find the name of Inspector Theofan (Kharitonov) mentioned in individual publications, periodicals, archival documents and works of fiction of the early 20th century. For each source, it was necessary to establish the context of writing, nature of the evidence and extent of its reliability. For anonymous tes- timonies, it was important to identify the author, on the basis of which one can make judg- ments about his competence and the reliability of his words. Much of the preparatory work resulted in the specific studies. The performed work led to a reliable reconstruction of spiri- tual and moral character of the ascetic in his Vologda period. Comparing various testimonies, the researcher has identified how Hieromonk Theodosius was perceived by his contemporar- ies from different social and public circles. The evidence presented is also of interest as the factual illustrations of pedagogical approaches adopted in religious educational institutions at the turn of the 19th and 20th centuries.

To analyze the outcomes of surgical treatment of severe combined kyphosis secondary to myelocele. Material and Methods. Retrospective analysis of outcomes in six patients operated on for severe combined kyphosis secondary to myelocele was performed. Correction and posterior instrumented bicortical fixation (PIBF) with expandable systems (VEPTR, TSRH) by type of dynamic bracing were used in patients with mobile kyphosis less than 30°. Correcting vertebrotomy at the curve apex with PIBF was performed for rigid kyphosis greater than 30°. Patients with severe kyphosis and bed sores in the area of the curve apex underwent halo-pelvic external fixation for extrafocal deformity correction, stabilization and creating conditions for soft tissue healing before corrective vertebrotomy at the apex of kyphosis and PIBF. Results. The average correction was 71 %. In all children support function of the spine was restored, and functional class and physical status improved. Conclusion. The choice of technique in patients with spinal hernia sequelae and progressive kyphosis should be differentiated depending on the size and rigidity of kyphosis and trophic complications. Degree of correction should be sufficient to consider deformity as compensated one. This assumes corrected contour of the spine, restored its support ability, increased volume of the deformed thorax, and improved respiratory function.

The generalization and analysis of complex geological, geophysical, and archaeological materials has allowed us to clarify and significantly amend the notion concerning the coastal territory of Karantinnaia Bay of Tauric Chersonese in the Hellenistic Period. The information obtained allowed the ones to draw the conclusions about the sources of the city’s water supply, the relationship of the cultural layer with the geological structure of the deluvial and proluvial deposits of the ravine, and the features of the ancient landscape and the coastline of Karantinnaia Bay. The results of engineering-geological, hydrogeological, geophysical, and archaeological works in Chersonesan Ravine and the coastal territory of Chersonese conducted from 2021 to 2023 show that the water-bearing strata of the ravine in question were one of the water supply sources of Chersonese. The main stratum belongs to the fracture-karst type. Owing to its slight mineralization, the water was good for supply. This conclusion is confirmed by the results of archaeological excavations that discovered the “water supply inlet” of ancient Chersonese, consisting of numerous wells cut in the bedrock in the thalweg zone of the ravine. In the ancient city area, the ravine can be seen as an erosional incision of a paleo-valley filled with sands, which comprise the main water-bearing stratum of the coastal territory. The stratum has a hydraulic connection with the seawater of Karantinnaia Bay. The degree of the groundwater salinity in this stratum depends on the sea level. The location of the wells and public baths in the coastal area of the town indicates that the stratum (horizon) provided stock water, for the sea level in the ancient period was significantly lower than today. The sources of water supply in Chersonesan Ravine and the coastal territory of Karantinnaia Bay could be interpreted as one of the important city-forming factors in the Hellenistic Period of Chersonese. The geological section of the deluvial and proluvial deposits of Chersonesan Ravine is represented by a layer of loams forming a cultural layer shaped from the fourth century BC to the thirteenth century AD. The relationship of the cultural layer with the geological structure points to the fact that the accumulation of deluvial and proluvial deposits in the ravine was caused by the activities of Chersonesan inhabitants in the adjacent territories of the Gerakleiskii Peninsula. The structure of the geological and archaeological section confirms the presence of a seasonal water stream in Chersonesan Ravine, which carried proluvial deposits throughout the entire period when the city existed. The significant thickness of the loamy layer behind the proteichism, in contrast to the one observed in the peribolos, may appear in result of the ancient proteichism protecting the peribolos not only from enemies, but also from the flow of proluvial deposits going down from Chersonesan Ravine. Taking the absolute marks of the cultural layer bottom certified by the wells, a detailed map of the bottom relief of Karantin Bay coastal zone, the data obtained by the method of bottom electrotomography, and the established sea level at absolute marks of minus 3–4 m into account, we have determined the contours of the coastline of the bay in the early period of Chersonese
