One of the key problems in the development of nanosatellites is to provide a given temperature range for the operation of the on-board computer. The constantly increasing information load leads to the need to use more advanced processors with high thermal design power (TDP). The indicated thermal regime of processors can be achieved using remote heat removal systems - miniature loop heat pipes. Using a model of nanosatellite as an example, a thermal control system with miniature loop heat pipes is designed. The simulation was carried out in the Siemens NX program in the elliptical and geostationary orbits of the Earth. The cooling schemes of the processor with a thermal power of 15 W using one and two loop heat pipes are considered. Calculations showed that the use of loop heat pipes can reduce the processor temperature to acceptable values. The anisotropy of the thermal conductivity coefficient in the reinforcement plane of the composite material of the nanosatellite case can have a significant effect on the temperature of the processor. This opens up prospects for the use of anisotropic composite materials to ensure the thermal regime of the nanosatellite.

The image of a falcon in “The Tale of Igor’s Campaign” and ancient Chinese literature is analyzed. The material for the study was the original text of “The Tale”, its translations and comments to them by Chinese literary scholars Wei Huangnu and Li Xiyin, as well as famous ancient Chinese works. One of the main motives of the artistic and pictorial ornithology of “The Tale” is examined in detail — the individual and personal images of the falcons-Russian princes, opposing the spontaneity, chaos of the bird flock as an enemy horde. In ancient Chinese literature, the ornithological figurative complex serves as a symbol, firstly, of elite divisions, strong troops; secondly, a person filled with high motives, both heroic and career ambitious; thirdly, the authority of the monarch or some other important person in power. The novelty of the research is seen in the fact that for the first time the mythologeme falcon of “The Tale” is considered in intertextual comparison with the works of ancient Chinese literature. It is concluded that the symbolic connotations of the falcon both in ancient Chinese literature and in “The Tale of Igor’s Campaign” are closely related to the real qualities of this bird’s behavior in its natural environment: bravery, courage, dexterity.

The article analyzes the image of the wolf in “The Song of Igor's Campaign” and ancient Chinese literature. In the motive complex of artistic animalism of “The Song” the wolf is represented semantically multivalued. He acts as a symbolic function of the forerunner of tragic events, poeticizes as a legendary mythological werewolf, and is also intensively used as a comparison-personification. In ancient Chinese literature the wolf in the vast majority of texts acts as a carrier of negative emotions. Its main metaphorical associations are alien invaders, rebels, sovereigns-tyrants. The image of the wolf is investigated according to the original text of “The Song” and the translations and commentaries of Chinese literary scholars Wei Huangnu and Li Xiyin.

The article explores the toponym “Kiev” as an universal center of the space - time organization of “The Song of Igor’s Campaign”. The capital city of Ancient Russia is mentioned in 10 episodes, in each of which it appears in the symbolic incarnation of a certain political slogan or poetic hyperbole. The study analyzes and compares the image of Kiev, displayed in the original text of “The Song”, its translations into Chinese, and commentaries by Wei Huangnu and Li Xiyin, who discovered the artistic value of the ancient Russian masterpiece to Chinese philologists and a wide circle of readers.

One of the key problems in the development of nanosatellites is to provide a given temperature range for the operation of electronic equipment, the heat transfer of which can be tens of watts. Thermoregulation systems traditional for large spacecraft are not suitable for nanosatellites due to limitations on their mass and size characteristics. The indicated thermal regime of nanosatellites can be achieved using remote heat removal systems - miniature loop heat pipes. In recent years, their mass production has been established in Russia, but they have not yet found wide application in nanosatellites. The aim of the paper is to substantiate the possibility of using miniature loop heat pipes to remove excess heat from the on-board computer processor to the carbon-plastic case of the nanosatellite. Parametric modeling of the influence of geometric dimensions and the values of the effective thermal conductivity coefficient of loop heat pipes on the processor temperature was carried out in the ANSYS program. Calculations showed that the use of contour heat pipes will reduce the processor temperature to acceptable values. The anisotropy of the thermal conductivity coefficient in the reinforcement plane of the composite material of the nanosatellite case can have a significant effect on the temperature of the processor. This opens up prospects for the use of anisotropic composite materials to ensure the thermal regime of the nanosatellite.

The article is devoted to the multimodal analysis of the representation of the national-cultural phenomenon “Confucianism” in the field of advertising in modern China on the examples of nationally-oriented advertising texts of different thematic varieties. The relevance of the work is due to the importance of preserving and continuing the heritage of Confucianism in modern Chinese society, especially in the media space. Particular attention is paid to the multimodal analysis of verbal and non-verbal means of expressing the key concept of Confucianism “five constancies of a righteous person” in Chinese nationally oriented advertising texts. It is shown that the concept of “five permanencies” as one of the important components of Confucianism gets its continuation in the field of advertising in modern China, develops in accordance with the social life of the Chinese people in the modern era. It has been established that the use of the Confucian idea of the five permanencies of a righteous person can be considered as one of the most important and effective ways to create advertising with the aim of influencing the target audience of the Chinese domestic market. The conclusions and results of the study allow us to get a general idea of the concept of the five constancies of Confucianism, as well as the practice of its application as methods of manipulating public consciousness in modern Chinese advertising, which is of great importance for sinological research in various scientific fields.
