Authors: Santanna Ekaterina A.
Published: January 2024

This research examined the ethical implications of using Telegram chats in college education, focusing on the Social Penetration Theory (SPT) to understand its impact on interpersonal relationships. The study aims to identify ethical dilemmas faced by lecturers and chat administrators. Data was collected from the Creative Industry Faculty in Novosibirsk, Russia, using hermeneutic phenomenological interviewing between February and April 2023. The sample includes six female lecturers (age M=35, SD=15) and three chat administrators (two female, one male; age M=20, SD=2), who provided written consent and used pseudonyms. The findings of this research revealed ethical concerns such as students seeking attention and engaging in provocative behavior through jokes and intolerant remarks. Students also desired more informal communication with lecturers, crossing boundaries by sharing personal problems and engaging in discussions involving partying, smoking, and alcohol use. These behaviors presented ethical dilemmas for lecturers and chat administrators, including decisions about sharing received information and addressing online behavior offline. The study highlights the need for ethical regulations in online college communication. Limitations include the small sample size, and future research should include more diverse groups of lecturers and officials from various college departments.

Published: January 2024

The limited quota and short time for the Hajj pilgrimage have resulted in quite long waiting lists. Many prospective regular Hajj pilgrims tend to choose other options, namely Hajj Plus or Umrah. The purchase decision of prospective Hajj Plus or Umrah pilgrims is influenced by several factors, one of which is word of mouth (WOM). This research uses a quantitative approach with a type of causality research. The sample was determined using an accidental sampling technique with a sample size of 100 respondents. The data analysis method uses simple linear regression. The research results show that word of mouth influences purchasing decisions. If pilgrims who have used Umrah and Hajj plus services increasingly provide recommendations through word of mouth, the confidence of prospective pilgrims in deciding to purchase Umrah and Hajj plus service products at PT Ebad Al Rahman Wisata Jember Regency will increase.

Research has been conducted on reducing the levels of free fatty acids in used cooking oil using activated carbon derived from teak sawdust doped with TiO2. The used cooking oil employed in this study underwent five frying cycles. The activated carbon was derived from teak sawdust and activated using a 10% ZnCl2 solution. The activated carbon was tested for moisture and ash content. The activated carbon was doped with TiO2 in various mass ratios, specifically 3:100, 6:100, 9:100, and 12:100, using solid-state synthesis at a temperature of 500 Â°C. The doped carbon was subjected to XRD analysis. The purified used cooking oil was tested for free fatty acid levels and clarity using UV-vis spectroscopy. The moisture content of the activated carbon was found to be 3.60%, while the ash content was 1.95%. XRD analysis revealed that the crystal size of the activated carbon was 38.9 nm, which decreased to 27.2 nm after TiO2 doping. Free fatty acid levels decreased from 1.18% to 0.29% in the free fatty acid content test. In the UV-vis measurement, the absorbance value for used cooking oil was higher at 4.5734, while purified oil had an absorbance value of 4.1985. The research results indicated that the best mass ratio of activated carbon to TiO2 was 9:100. The use of TiO2 doped activated carbon as an adsorbent effectively reduced the levels of free fatty acids in used cooking oil.

Rotor blade tip leakage loss influences turbine stage efficiency. A parametric optimization method based on five design variables combined with Non-Linear Programming by Quadratic Lagrangian to optimize the turbine efficiency estimated from computational fluid dynamics analysis has been used to obtain estimates of the optimal cavity depth and split rib location within the tip cavity, which appears to improve the stage efficiency by 1.5%. Besides the design point, the influence of the optimized tip cavity shape impacts the performance of the rotor at different rotational speeds and pressure ratios. In this study, by comparing different tip cavity shapes, it is shown that a dual-cavity shape on the rotor blade tip with a stream-direction split rib can effectively control the air flow bending angle inside the tip clearance and improve the aerodynamic performance. The compressible unsteady Reynolds-averaged Navier–Stokes model is used to verify the adaptability of the optimized tip cavity shape to periodic wake disturbances, and the results demonstrate that the time-averaged estimate of the efficiency can be improved by 1.3% compared to that of the flat rotor tip.

Batteries are the lynchpin of electric vertical takeoff and landing (eVTOL) aircraft, and the high discharge rates pose a critical challenge to the battery thermal management system (BTMS). This work presents a channeled liquid cooling technology-based BTMS for eVTOL aircraft. During the flight, the heat generated from the batteries is partly extracted by circulating liquid coolant within a wavy channel (WC) attached firmly to the battery cells. The heat is then transported into a plate-fin compact heat exchanger (HEX), where all the heat is dissipated into the atmosphere. We report sensitivity analyses of the HEX model to shed light on the impact of the relevant design parameters on the BTMS size, weight, and power. We also examine critical parameters of the coupled WC-HEX BTMS in a one-dimensional off-design analysis. We demonstrate that the liquid cooling system can maintain the battery operating temperature within acceptable levels with a mass of less than 20% of the battery pack mass. Battery degradation using the liquid cooling system is reduced by over three times compared to an air-cooled system for both tilt-wing and lift+cruise eVTOL aircraft.
Numerical simulation of wave propagation through a spherical particle within the framework of generalised Lorenz-Mie theory

Published: January 2024

Holography has been widely used for measuring and visualising transients in multiphase flows. Earlier, one of the drawbacks of this approach was the need to register on various photosensitive elements and its subsequent transfer to digital format and restoration. With the development of digital technologies, direct registration of interference patterns (holographic images) into a CCD matrix became possible. However, even in digital holography there are a number of problems that need to be solved. These problems pertain to recovery algorithms, efficient data processing and resolution, among others. Currently, the numerical implementation of the restoration and processing of holographic images can be done within the framework of classical diffraction theory or with the help of generalised Lorenz-Mie theory. The first implies an indirect solution of Maxwell's equations, i.e., application of the Huygens-Fresnel principle. The second approach involves a direct solution of Maxwell's equations for the holographic problem. In the framework of this work, a numerical simulation of holographic imaging of fields from spherical particles based on the generalised Lorenz-Mie theory is proposed. Within the framework of this work, a numerical implementation of modelling of holographic images of a homogeneous sphere based on the generalised Lorenz-Mie theory is presented. The implementation code in the python programming language is presented. The results of the study demonstrate the possibility of effective use of digital holography for visualisation and analysis of spherical objects.
Morphometric parameters of R. Dikuscha berries and the content of biologically active substances in relation to the place of growth
Authors: Kolesova L. A. , Solovyeva M. I.
Published: January 2024

Antioxidants in plants have specific organ and tissue tropisms and different points of application. The physiological realisation of antioxidant effects is closely related to the chemical and spatial structure of their molecule: each functional group within the molecule has a specific molecular target - a kind of “point of activity”. This approach opens up the prospect of developing new, more effective antioxidants [1]. Black-fruited berries are an excellent source of the pigments anthocyanidins - polyphenolic compounds with unique antioxidant activity - ascorbic acid and other essential vitamins. Dark berry seeds are rich in unsaturated fatty acids. At the same time, berries have a unique composition of micro- and macroelements such as potassium, magnesium, zinc, manganese and copper, which are active participants in the redox reactions of the body and ensure the work of all links of the antioxidant defence of the body [2]. Among all dark berries, the fruits of black currants and their relatives have not only a higher content of ascorbic acid and a rich mineral composition, but also the densest skin, which accumulates the most promising antioxidant group of polyphenols - anthocyanidins. Such a combination on the principle of synergism represents the prospect of high efficiency of antioxidant action of the phytocomplex. The aim of the research was to determine the content of biologically active substances in the fruits of the wild currant Ribes dikuscha Fisch. Furthermore, the morphometric parameters of R. dikuscha fruits were described as a function of growing location. In this research, for the first time the content of biologically active substances with antioxidant properties in the fruits of Ribes dikuscha Fisch. was studied; also, a comparative analysis of biologically active substances and morphometric parameters of the R. dikuscha fruits depending on growing places was conducted. It was concluded that there was a negative correlation between the size of the fruits and the total content of low-molecular antioxidants in the berries; on the contrary, there was a positive correlation between the thickness of the outer skin of the fruits and the quantitative content of polyphenolic compounds in Ribes dikuscha Fisch.
The motif of returning home in the lyric poetry of Nikolay Rubtsov and Leonid Zavalnyuk
Authors: Gavrilenko V. D.
Published: January 2024

The article is devoted to the study of the motif of returning to one’s homeland in the poetry of Nikolay Rubtsov and Leonid Zavalnyuk. The biographical research method makes it possible to identify the reasons that make the motif of returning to one’s homeland one of the key motifs in the poetry of Rubtsov and Zavalnyuk. The childhood of the poets, the early lost of mothers, the war years, both being orphans with living fathers, and being forced to leave their homes for many years. A comparative typological analysis allows us to identify the commonality in the revelation of this motif: the return to the homeland as a return to the idyllic world of lost childhood. Moreover, in the poems of both poets the image of their small homeland is presented in two time dimensions: past and present. Using the technique of contrast, the authors show the radical changes in the native space, the inability to accept the changes that have occurred. A comparison of the motif of returning to home reveals not only the similarities, but also the differences in the worldview of the two poets. Turning to the image of a small homeland, Rubtsov continues Yesenin’s traditions, his attention is directed to the Russian village, rural nature, the motif of the death of the traditional way of life. For Zavalnyuk, the motif of returning to his homeland takes on a new meaning: returning to his true self, restoring his own integrity, accepting himself. The analysis of poetic texts is based on the works of A. N. Veselovsky, B. M. Gasparov, M. L. Gasparov, N. D. Tamarchenko, V. I. Tyupa. The results of the study can be applied when studying the history of Russian literature and literary local history at universities and schools.
Communicative accentuation in Buryat emotive constructions
Authors: Darzhaeva N. B.
Published: January 2024

The article examines Buryat emotive constructions from the point of view of the communicative identification of participants in an emotive situation. The relevance of the study lies in the current general interest of linguists currently in the problem of the verbalisation of emotions. The novelty of the work lies in the application of an additional, communicative aspect to the study of the means of verbalising emotiveness in the Buryat language. The aim of the study is to identify the connection between the syntactic and communicative structure of a sentence, or more precisely, between the syntactic position and the communicative emphasis. Methods of linguistic observation, introspection, description, methods of differential and component analysis have been used. It has been shown that a shift in the speaker's focus from one participant to another, or to the emotion itself, is reflected in the syntactic structure of the sentence. The position of the subject is communicatively highlighted and significant in the structure of the sentence. The communicative emphasis of the subject in the Buryat language is also determined by the strict order of words in the sentence (the subject is always the topic). In the course of studying Buryat emotive constructions as speech acts, the author identified three types of constructions with communicative emphasis of the participants in an emotive situation in the subject position. These are constructions with a communicative emphasis: 1) on the Experiencer, 2) on the Stimulus, 3) on the Emotion itself. It is noted that the Stimulus can be presented both in expanded form (subordinate clauses) and in collapsed form (nominal groups). The research material was modern texts of literary works by Buryat authors, published in the electronic Buryat corpus. A survey of native speakers was also conducted in order to confirm or refute doubtful cases of communicative emphasis.
Linguistic features of spontaneous speech of the Anabar Dolgans (On the material of the expedition work)
Authors: Ivanov V. V. , Malysheva N. V.
Published: January 2024

The current functioning of the Yakut language and the languages spoken by the indigenous peoples in the North of the Republic of Sakha (Yakutia) is under extensive scrutiny from various researchers. This interest stems from the fact that numerous languages of the northern and arctic territories are on the verge of becoming extinct owing to the impact of several anthropogenic factors. The article aims to identify linguistic characteristics of live speech amongst residents of the Yuryung-Khainsky Rural Okrug of the Anabarsky District. These speech patterns were recorded during the 2021 fieldwork conducted as part of the “Preservation of linguistic and cultural diversity and sustainable development of the Arctic and Subarctic of the Russian Federation” project (Agreement № 075-15-2021-616 from 07.06.2021). The spontaneous speech of five respondents, residents of the study area, was analysed. When analysing the empirical data, a range of methodologies was employed, including sociolinguistic and descriptive methods, as well as structural, quantitative and statistical analysis. Upon analysing the linguistic material, it has been determined that the language of the Anabar Dolgans is comprised mainly of words of Yakut origin. Additionally, the respondents also utilise Dolgan vocabulary and words of foreign origin, such as Russisms and Evenkisms. Despite the influence of various languages, several words used by Anabar Dolgan speakers have retained their original semantic meaning, identical to those in the Yakut language. However, the extensive usage of Russian in educational, administrative, and industrial domains has resulted in a high level of incorporation of Russisms in respondents' speech, without proper adaptation to Yakut and Dolgan language norms. The Anabar Dolgan language presents an excellent illustration of linguistic synthesis and cultural convergence among northern peoples and holds significant linguistic and cultural value. Ongoing linguistic transformations occurring within the Yuryung-Khainsky Rural Okrug pose a distinctive situation that calls for in-depth examination of the language through theoretical and empirical approaches.
Experimental Study On The Use Of Strapping Band Variation As A Substitute For Steel Reinforcement In The Manufacture Of Precast Foundation For Coastal Construction
Authors: Sitohang Maria Septhree Winna , Elvira Elvira , Supriyadi Asep
Published: January 2024

A solid foundation is a concrete mix using steel reinforcement, but the reinforcement has the disadvantage of being corrosive when used in coastal areas. Therefore, this research uses strapping bands as a substitute for steel reinforcement. This research is focused on the manufacture of mortar plates for lightweight construction, especially in foundation parts such as footing foundations.  This research used 5 (five) variations of slab mixture including, variation A1 which is mortar slab without additional strapping band, variation B1 which is mortar slab with additional 3 pieces of strapping band as thick as 1 layer on each top and bottom layer, so on up to variation B4 as thick as 4 layers. The results of the mortar plate bending test obtained the value of the bending moment of variations A1, B1, B2, B3, and B4 are 0.148 kN.m; 0.183 kN.m; 0.222 kN.m; 0.278 kN.m; 0.325 kN.m. Then the maximum bending moment value is averaged in the variation that uses a 4-layer thick strapping band. From this research it can be concluded that to get a high bending moment value, the more strapping bands are used.
