In this paper, the authors investigated the system of propellant supply to the combustion chamber (CC) of the first stages of a liquid-propellant rocket engine. Depending on the purpose of the rocket engine, either a turbo-pump system of fuel supply or a displacement system is used. The displacement system is used for low thrust and short-term engine operation, as well as for flights in outer space, so this scheme is not considered in this article. The turbopump system of fuel supply is more preferable for the first stages of launch vehicles (LV), as it can provide the necessary pump power to achieve the required engine thrust. However, TNA is a complex system with complicated manufacturing technology. In this regard, this paper proposes to replace the turbopump unit with an electric pump unit, which will greatly simplify the production, operation and circuit diagram of liquid rocket engines.

In the work a quantitative analysis of the photometry of the Gravitational Microlensing Phenomenon
(GMP) of a background star of the Milky Way by a Massive Dark Body (MDB), located on the
Solar System Periphery (SSP) are made in the case of five model bodies. The total luminous flux and
its magnification (A) are calculated. Formulas for the microlensing time (T0) and mass of microlens
are obtained. It is shown that in the case of the Nemesis/Tyuche models, the strong microlensing
for their registration are realized almost in the entire Space of Model Free Parameters (SMFP) and
optimal conditions of registration are achieved at the upper boundary of the Interval Possible Values of Heliocentric Distances (IPVHD). 

In this work, qualitative and quantitative assessments of the content of secondary metabolites of lichens of the following species were carried out for the first time: Cladonia fimbriata, Evernia mesomorpha, Hypogymnia physodes, Parmelia sulcata, Xanthoria parietina – by microcrystallization and spectrophotometric method, and also studied the dependence of the accumulation of lichen substances on the position in the relief and the type of community. In the thallomas of the studied species, 6 secondary metabolites were found: atranorine, divaricatic, salacinic, physodalic, fumarprotocetraric acids and parietin. The microcrystallization method showed that the predominant amount of lichen acids is formed in communities in the arena, and only fumarprotocetraric acid is found in greater quantities in floodplain oakwood. And the method of spectrophotometry showed that in the thallomas of Parmelia sulcata, Hypogymnia physodes and Evernia mesomorpha, the total content of lichen acids is higher in floodplain communities than in those in the arena, and in Xanthoria parietina and Cladonia fimbriata – on the contrary.

In this paper, the authors consider the problem of determining the gender of the author of an electronic message. To solve it, a computer program has been developed that, based on statistical methods, is able to determine the gender of the author of the text. A method for collecting and analyzing a large number of electronic messages is proposed to form a training sample of a text corpus in Russian. On its basis, a number of tests were carried out in order to find the most effective approach to training programs to determine the required information about the author of the message. In addition, the paper presents and analyzes the results of the experiments, as well as their analysis to further improve the accuracy of such programs.

This paper presents the development and description of automated system for analyzing the digital footprint of a VKontakte social network user.

In this paper, the author presents an attempt to create a general description of modern (1990 - present) foreign (primarily Anglo-Saxon) and domestic works on Anglo-French relations in the second half of the 16th century. The subject of the study will be the historiographic base on this issue. The literature under consideration will be analyzed in chronological order, which will make it possible to trace the change in trends, views, both in foreign historical science and in the domestic one. In more detail, in terms of highlighting chronological periods and methodological techniques, domestic historiography has been worked out, since fewer studies by foreign historians have been selected for consideration and almost all of them belong to the same chronological period.

This work examines the the poetics of spatial and temporal organization in the works on Christmas theme by European and Russian writers. The subject of the study is the chronotope of such Christmas stories by European authors as: 1) "A Christmas Carol in Prose" by Dickens, 2) "The Girl with Matches" by Andersen, 3) "The Nutcracker and the Mouse King" by Hoffmann. A group of works by Russian writers is represented by the following works: 1) "The Night before Christmas" by Gogol, 2) The chapter "Christmas" from the book "The Summer of the Lord" by Shmelev, 3) "The Beggar Boy at Christ’s Christmas tree" by Dostoevsky.

It was noticed that in the works of this orientation, there are often motifs of a magical journey, a Christmas miracle, the struggle of good and evil and home festive comfort. The Russian awareness of this religious holiday is also distinguished by the sacralization and Christianization of the space.

The article examines how the Russian-language adaptation of the cycle of fantasy novels created by K. S. Lewis was able to convey to the domestic reader the mythological images and motifs embedded in them by the author and how it transplanted the biblical meanings present in the original text. In the course of the work, the history of the creation of the cycle of stories "Chronicles of Narnia" was studied and the reasons why their publication in the USSR was impossible were described. The complexity of the transmission of individual moments of the text in Russian is analyzed and it is revealed that the untranslatable wordplay affects the perception of allusions by readers who do not speak English. Some examples show how the original text of the works is distorted during the Russian-language adaptation and how, despite the inaccuracies of the translation, the Russian-language edition copes with the task of reproducing the biblical meanings inherent in the works.

This article examines how trauma is manifested and verbalized in a work of fiction of the XXI century, i.e. how the "narrative of trauma" is created. The study fits into the paradigm of trauma studies; through the prism of the analysis of the perception of the body (physicality) by the characters of the novel, it is revealed which strategies the author chooses to represent a traumatic event. It is revealed that in the hero's mind, the mechanisms for facilitating the perception of difficult and unthinkable situations, phenomena and objects that cannot be directly embedded in the symbolic structure are the perception of traumatic events and images through simple and safe images, objectification of the traumatic abstract phenomenon and alienation from it, the description of the living as normal, the dead as going beyond the norm etc. In addition, this article reveals the features of the artistic world of Roman Z. Prilepin, related to the plot-forming event of the work, which is traumatic in the life of the hero.

The article is devoted to the analysis of the verbal and conceptual plans of aphorisms as a variety of small-format texts within the English fiction discourse. The empirical base includes 100 aphoristic texts written by classical authors. It is established that due to the extreme brevity of the verbal textual plan, the pragmatic potential of the aphorisms is realized primarily through expressive means and stylistic devices. Furthermore, a set of concepts verbalized in the aphorisms is identified. On the example of the concept “Human relations” the ways of its language representation are revealed and the typical features of conceptualization within the considered discourse are identified.
