Authors: Abd Kati Firas
Published: January 2024

Introduction: Heat cured resins are commonly utilized for construction of complete and partial dentures. Such materials have poor mechanical properties and may be exposed to fracture. The present study, therefore, was conducted to evaluate the impact of incorporating ZnO on acrylic resins’ surface hardness. Materials and Methods: Twenty specimens were constructed in total. The study composed of 2 major sets, and each set had ten specimens. The 1st set had 1% zinc oxide and the second group had no zinc oxide and considered as control. All samples were subjected to the hardness test three times and average reading was recorded for all specimens. Results: a significant decrease in the surface hardness of acrylic re sins following the incorporation of ZnO (control group: 12 7.62+2.53 g/mm2, zinc oxide group: 106.67+ 1.51). Conc lusions: The addition of zinc oxide at 1 % would decrease the surface hardness of acrylic resins.

Published: January 2024

The object of the study is families living in the Republic of Bashkortostan. The subject of the study is the resource capital of a family with children. One of the important areas of research is the consideration of a family with children in the aspect of a resource approach. The relevance of the study is determined by the need to monitor and assess the needs and access to social benefits and services of families and their members, which will determine some mechanisms for improving their socio-economic status, respectively, well–being and quality of life, and will also determine the characteristics and degree of influence of various types of its capital in family education. The paper uses statistical data analysis, secondary analysis of sociological research data on related issues. The actual basis of the study was the data obtained during the study of the living conditions of the population in 2022 in the Republic of Bashkortostan conducted by the state statistics bodies. The paper considers the current socio-economic status of families living in the region. The factors causing the risk of reducing the well-being of families with children are identified, the directions of their impact are determined. Based on the data presented, it is shown that the risk of a decrease in the material well-being of families with children in the region is primarily caused by factors such as having many children and living in rural areas. The paper shows that the financial capital of families with children for a significant part of them acts rather as a factor limiting development opportunities and access to social goods and services. The social capital of families can act as a compensating factor and even expand life opportunities, in particular, in the field of education. Some mechanisms of leveling the factors that reduce the well-being of families with children are indicated.
Folk arts and crafts of Ugra: problems of terminological interpretation
Authors: Moldanova Nadezhda Anatolyevna
Published: January 2024

The purpose of the study is to analyze the concepts of "folk arts and crafts" and their comparison with folk and decorative arts. The use of materials on the culture of the Ob Ugrians allows us to define the boundaries of these phenomena, which are interpreted differently in legal, educational and cultural contexts. The concepts of "folk arts and crafts" and "folk art" have similarities in that they both relate to traditional forms of culture that were created and passed down from generation to generation by the people. The concept of "decorative and applied art" includes various objects of art that are created for the purpose of decorating clothes, dishes, and interiors. The equivalence of these concepts lies in the fact that this activity of creating handmade products has unique artistic qualities. The materials for the study were the works of Soviet and Russian art historians and ethnographers. The author relies on the fundamental research of the art historian M.A. Nekrasova on the theory of folk art. Special attention is paid to the works of northern historians specializing in the traditional art of the Ob Ugrians. The article analyzes the conceptual framework in federal and regional legislation. Having studied various forms of artistic creativity – folk crafts and folk art, we have identified their specific features, which were formed under the influence of historical, socio-economic, cultural changes. Adherence to tradition is an important feature of the folk culture of the indigenous peoples of the North, which allows us to preserve its unique characteristics. Folk arts and crafts of the Ob Ugrians today continue to develop and adapt to modern realities, while maintaining their identity. Folk art and crafts have a special system of meanings, which are determined by their history, functioning, and specific expression, including in modern reality. The folk art of the Ob Ugrians has its own trajectory of development within the settlement of these peoples. At the same time, all traditional culture has deep roots in the ethnic environment and is transmitted through mechanisms related to ethnic identity and social translation.

Authors: Karimov Aibulat Galim'yanovich
Published: January 2024

The paper discusses theoretical, methodological and practical aspects of the diagnosis of social capital. The analysis of existing approaches to the study of social capital is carried out. The relevance of the consideration of social capital from the perspective of taking into account socio-cultural changes taking place in society is substantiated. A methodological tool for assessing social capital is proposed, characterized by the integrative nature of the use of statistical and sociological indicators. The list of the main diagnostic indicators of the social capital of the region is systematized and presented. Based on the analysis of the results of sociological research, an approximately equal level of closed and open social capital in the Republic of Bashkortostan was revealed, as well as a relatively low level of institutional trust. The necessity of strengthening social cohesion on the basis of increasing trust in interpersonal, intergroup relations, as well as in relations between society and state institutions is proved. The results of a sociological study conducted in 2021 were used as the methodological basis of the study. Institute of the History of Language and Literature of the UFIC RAS and the sociological survey of scientists of the Ufa Research Center of the RAS (Ufa, Republic of Bashkortostan) (2023) conducted with the direct participation of the author. The novelty lies in the fact that the methodological tools for assessing social capital are proposed, characterized by the integrative nature of the use of statistical and sociological indicators, which allows for the diagnosis of social capital at 3 levels: institutional, corporate and individual levels. The use of such tools will allow measuring the effects of social capital on socio-economic development, as well as identifying communities with high and low levels of social capital, identifying social groups that are in a vulnerable position with respect to social capital. Obtaining such data contributes to the development of systematic and targeted measures aimed at increasing the level of social capital and increasing the efficiency of its use. The low level of institutional trust is revealed, the need to increase the level of social cohesion as a basis for strengthening the relationship between society and state institutions is substantiated.
Etude Genre in the Works of Contemporary Pianists-Composers: Traditions and Innovation
Authors: Sycheva Natalia Nikolaevna
Published: January 2024

The article is devoted to the study of the etude genre, which in the work of domestic composers-pianists of the second half of the twentieth – early twenty-first centuries became an experiment and capture of a personal artistic picture of the world. The focus of the article is two opuses by contemporary pianist composers М. Kollontai and E. Chernov. As a result of the cycle of analysis of etudes op. 55 Kollontai, the author comes to the conclusion that this work continues the line of Liszt’s transcendentalism. Particular attention in this cycle is aimed at considering religious and spiritual themes expressed at the verbal level. The composer’s artistic comments on the etudes, the epigraph from the poems of the poet and Catholic priest Geselle, the afterword to the plays, explain and explore the conceptual field of the program composition, which embodied New Testament stories related to the way of the cross of Jesus Christ on earth. For the piano cycle – Nine etudes-pictures op. 11 by Chernov, nine etudes-pictures op. 39 Rachmaninoff. In the course of the analysis, it is noted that the cycle of etudes by Chernov is characterized by the following features: a concentric type of composition with an aspiration to the finale, the presence of a lyrical core, the development and interweaving of two psychological modes (lyrical and dramatic), which gives the cycle integrity and harmony, paired grouping of etudes according to the principle of contrast, the presence of leitmotifs, as well as leitgenres (nocturne and waltz) that permeate the piano cycle. The article emphasizes the idea that interest in such a genre of improvisational mix as «etude-fantasy» is found mainly in the legacy of virtuoso composers-pianists of the 19th-20th centuries, striving in their work to prolong romantic traditions.

Authors: Pokela Royce , Kumar Rajan , Vasile Joseph D , DeSpirito James
Published: January 2024

A combined experimental and numerical study was conducted on a generic projectile configuration with low-aspect-ratio fins. The main objectives of this study were to characterize the aerodynamic behavior and validate numerical simulations for a range of Mach numbers (0.4–4) to facilitate an understanding of major flow features such as forebody and fin-generated shock waves, crossflow shear layer vortex, and fin vortex interactions. Measurements included forces and moments, surface oil flow visualization, and high-speed shadowgraph imaging. Numerical simulations were performed using the CFD++ solver. The results showed an excellent match between the experimental and numerical force and moment data. Pressure contours obtained using numerical simulations were integrated to obtain the contributions of individual components toward the total normal force on the body. Flow visualization results show a few complex and interesting flow features, such as shear layer roll-up, crossflow and fin tip vortex interactions, and shock-wave–boundary-layer interactions. The effects of vortex strength and location were analyzed to determine their contributions to the overall forces on the model. The database generated will be very useful for further validation of the numerical tool and a better understanding of vortex-dominated supersonic flows.
Three-Dimensional Aeromechanical Analysis of Lift Offset Coaxial Rotors: A Helios Test Case
Authors: Patil Mrinalgouda , Datta Anubhav
Published: January 2024

Three-dimensional (3-D) solid finite element analysis (FEA) is used to model and study coaxial helicopter rotors. The 3-D FEA is coupled with a lifting line aerodynamic model with free wake to capture rotor-rotor interactions. Two open-access models are developed: one is the Metaltail (a hingeless coaxial rotorcraft), and the other is the coaxial rotor built from articulated UH-60A-like rotors. The former is the main focus of this work and is developed as an example case for the U.S. Army/DoD rotorcraft simulation software CREATETM–AV Helios, while the latter is merely for a regression test. The analysis is performed on a low-speed transition flight for which qualitative data are available for the Sikorsky S-97 Raider aircraft for comparison. Predictions of performance, airloads, vibratory loads, and 3-D stresses are discussed. In the absence of available geometry or property data of the S-97, this study is primarily meant to serve as a capability demonstration of 3-D rotor structural dynamic modeling for such rotors.
Modification of the Class-Shape-Transformation Parameterization Based on Radial Basis Functions
Authors: Du Bingchen , Lu Zhiliang , Guo Tongqing , Zhou Di , Li Qiaozhong
Published: January 2024

To improve the capacity for utilizing a higher number of design variables and handling complex geometries in the class-shape-transformation parameterization method, this paper introduces an alternative for the shape function that employs radial basis functions to interpolate the deformations of the control points throughout the entire shape function. Two representative airfoils are parameterized first, and the results indicate that the presented method can avoid the ill-conditioning problem encountered when using high-order Bernstein polynomials in the traditional method. Moreover, it is more effective in parameterizing complex geometries. A comprehensive test on a database containing 1433 airfoils reveals that the presented method can cover a larger design space with an increase in the number of design variables. The presented method is further employed and validated in two typical aerodynamic shape optimization tasks: an airfoil inverse design and a benchmark problem for drag minimization in transonic viscous flow. The results suggest that the presented method has potential advantages in gaining better optimized results when more design variables are employed.
Assessing the Impact of Metrics on the Choice of Prognostic Methodologies
Authors: Bieber Marie , Verhagen Wim J. C. , Santos Bruno F.
Published: January 2024

Over the past years, advanced prognostic models and approaches have been developed. Most existing approaches are tailored to one specific system and cannot adaptively be used on different systems. This can lead to years of research and expertise being put into implementing prognostic models without the capacity to predict system failures, either because of a lack of data or data quality or because failure behavior cannot be captured by data-driven models. In addition, prognostic models are often evaluated using metrics only related to the correctness of predictions, preventing meaningful evaluation of operational performance. This paper makes use of a framework that can automatically choose prognostic settings based on specific system data. It simultaneously optimizes the choice of methodologies using metrics that capture multiple aspects of prediction quality. We apply this framework to both a simulated data set and a real aircraft data set to characterize the impact of metrics on the choice of prognostic methodologies. The results show that the choice of optimization metric greatly impacts the output of the generic prognostic framework and the overall performance. In addition, a definition for data suitability is provided and assessed on the aircraft system data sets.

Origins of the cosmopolitan approach in philosophy
Authors: Koriakina A. A.
Published: January 2024

In the modern globalized world with an increasingly intense contact between cultures and nations, there is a need to develop new philosophical concepts that can unite and overcome differences between people of different cultures and nationalities. One such concept is the cosmopolitan approach, based on the idea of global citizenship and the unity of all people. The origins of the cosmopolitan approach can be found in the evolution of philosophy over the centuries. In different national and cultural traditions, ideas about the unity and interconnection of all living in the world were manifested. This article analyzes the ancient and enlightenment origins of the cosmopolitan approach in philosophy, their comparison, as well as the prospects for the cosmopolitan approach in modern philosophy. Various philosophical traditions are examined, their influence on the formation of cosmopolitan thought, as well as their relevance in the modern globalized world. Particular attention is paid to the ideological milestones in the development of the cosmopolitan approach and its role in overcoming differences between cultures and nations. It is noted that cosmopolitanism, both in Ancient Greece and during the Enlightenment, was an important philosophical and cultural movement that laid the foundations for thinking about universal citizenship and the common purpose of humanity, about the importance of universal values and human rights. It is concluded that the influence of ancient and Enlightenment cosmopolitanism on the cosmopolitanism of the 21st century is manifested in the general idea of the unity of the universe and universal moral principles, in the development of global consciousness, emphasis on reason and cooperation.

Published: January 2024

In this article, the authors examine the historical and current state of the languages of the nationalities of Vietnam, as well as the current situation in teaching foreign languages in the country. The history of the Vietnamese language begins from the 8th – 9th centuries and has undergone various changes. The researchers came to the conclusion that the Vietnamese language was formed from a mixture of many languages. The authors note that at the state level in Vietnam, much attention is paid to the problem of developing not only the state language, Vietnamese, but also to the problem of developing the languages of national minorities living both within the country and abroad. For this purpose, appropriate and effective policies are developed and decisions are taken accordingly. A consistent language policy at the present stage is developing in three directions: preserving the linguistic variety of the country, especially the languages of small nationalities; preserving the Vietnamese language in the country, as well as its promotion throughout the world; Learning foreign languages. Particular emphasis is placed on the analysis of the distribution and promotion of the Russian language in the state in the past and today, in general, and the teaching and learning of this language at the Hanoi University of Entrepreneurship and Technology, in particular. The development of specific projects for the dissemination of the Russian language and their implementation are gradually improving its current situation in Vietnam. The authors come to the conclusion that the language situation is constantly changing over time and this depends on a number of factors such as demography, linguocultural, socio-psychological development, etc.

The concept of «movement» in Evenki phraseology
Authors: Varlamov A. N.
Published: January 2024

The publication is devoted to the description of the concept of «movement» in the ethnic picture of the world that is reflected in Evenki phraseology. The relevance of the research is the decline in the functionality of the native language in the conditions of globalization and is determined by the insufficient knowledge of Evenki phraseology. The aim of the research is to demonstrate the potential of figurative speech and the correlation between language and ethnic worldview on the example of a linguistic concept. The basic concept of the Evenki worldview is considered through the prism of the mentality bearer of ethnic culture that is based on the ethnographic traditions of the nomadic way of life. The theoretical basis of the research are the studies devoted to the phraseology of the Russian language and interdisciplinary developments at the interface between linguistics and ethnography. The research material are studies on the language, ritual culture, folklore and literature of the Evenki. The analysis of the used material and cultural traditions indicates a close correlation between the composition of phraseological units and the economic and worldview traditions of the Evenki. Because of the research, the author concludes that the concept of «movement» is one of the basic symbols of the traditional Evenki worldview, formed in the process of historical adaptation of the cultural complex of a nomadic hunter in the conditions of the mountain taiga landscape. In the ethnic picture of the world, this concept is comprehended in connection with the process of human life and is embodied in a significant amount of phraseological units formed from verbs denoting various forms of movement. The most common phraseological units are formed from the verbs ngaenaemi – «to go» and girkumi – «to walk». In the Evenki language, the concept of «movement» is represented in the form of phraseological units with different meanings, among which the most common are phraseological units meaning «to live», «to overcome», «to achieve», «to catch up.» In the Evenki language picture of the world, movement is contrasted with the static condition of objects in the world. The phraseology of the Evenki language reflects the ethnographic, social, moral traditions of the ethnic society and the system of acquired knowledge. The prospects for further research on the topic are associated with attracting interest in the Evenki phraseology from specialists in linguoculturology.

Published: January 2024

Linguistics is one of the social sciences and studies the various characteristics and functions of language. Various features of the internal system of language are also studied in relation to linguistics. At the same time, linguistic knowledge develops and changes under the influence of external social phenomena. The authors of the article are convinced of this property of language by applying natural science teachings to the object. This can be argued as a conflictological aspect of linguistics. This means that the conflictological aspect can prove the relevance of the article. The purpose of the article is to differentiate the scientific conclusions of the first Kazakh linguists of a linguobiological nature. This goal requires the solution of at least two tasks: 1) introduces the first Kazakh linguists to the common Eurasian scientific environment and disseminates their scientific and pedagogical works; 2) obliges to solve general interscientific relations through the relations of man and language, language and biology, language and speech, language and thinking. The first scientific works of the first Kazakh scientists are considered as the methodology of the article. In particular, the scientific principles of A. Baitursynuly, K. Zhubanuly, S. Amanzholuly were in the spotlight. Given specific examples and facts related to Turkic languages (Kazakh, Chuvash, Yakut) were given. In addition, materials from the dictionary of the Kazakh literary language and information from Wikipedia provided a lot of methodological information. The article is based on the methods of historical comparison, scientific analysis, analysis and collection. The main results of the article are reflected in the connection between linguistics and natural science. Likewise, the problems of paleontology and pathopsycholinguistics, presented in a small volume, make researchers think and lead to the study of general scientific research in this direction.

The relevance of the study is determined by the growing interest of the scientific community in constructing typologies of linguistic features of the Korean language in its relation to the Altai language system. A review of research shows that to date, discussions regarding the place of the Korean language in the Altai language system continue, since there are no uniform criteria by which to describe the relationship of these two languages. The purpose of the article is to systematize the features that allow us to determine the place of the Korean language in the Altai language system. Objectives: provide an overview of studies of the Altai language system; consider arguments about the relationship between the Korean and Altai languages; consider criticism of the theory of kinship between the Korean and Altaic languages. Research methods: systematization, generalization, description, comparison, critical analysis. It has been established that even if we completely deny the family connection between the theory of the Altaic language family and the Korean language, it is still possible to establish a friendly connection between them, which can be taken as a research hypothesis. This is made possible by the fact that the common elements that have been clearly outlined so far exist, albeit in meager quantities. If these elements were not borrowed, it would be difficult to conclude that this is a coincidence. However, it does not seem convincing that the scant data is sufficient to prove the kinship of Koreans and Altai. In this situation, just as it is impossible to draw an unambiguous conclusion that the Korean language has a related relationship with the Altai language or the Altai language family, it is also impossible to conclude that there are no such relationships at all. It is true that the origins of the Korean language are still unclear. Since the existing theory of the Altaic language family and the theory of kinship with Korean were accepted almost without criticism, the counter-arguments against them can be equally strong. However, there are significant differences between these views. Some say this completely refutes conventional wisdom, while others say it is a hypothesis that has not yet been proven. The prospects for the study are seen in the systematization of linguistic typological features of the Korean language in its relation to the Altai language system.

Developing effective antibacterial solutions has become paramount in maintaining global health in this era of increasing bacterial threats and rampant antibiotic resistance. Traditional antibiotics have played a significant role in combating bacterial infections throughout history. However, the emergence of novel resistant strains necessitates constant innovation in antibacterial research. We have analyzed the data on antibacterials from the CAS Content CollectionTM, the largest human-curated collection of published scientific knowledge, proven valuable for quantitative analysis of global scientific knowledge. Our analysis focuses on mining the CAS Content Collection data for recent publications (since 2012). This article aims to explore the intricate landscape of antibacterial research while reviewing the advancement from traditional antibiotics to novel and emerging antibacterial strategies. By delving into the resistance mechanisms, this paper highlights the need to find alternate strategies to address the growing concern.

Recent decades have shown arising growth-on-demand of integrating the machine learning into all areas of chemistry and materials science. In this study, we consider one of the aspects of applying these technologies to gain advantage in the search for new knowledge extracted from experimental data obtained in ever-growing number of studies. The novelty detection approaches are aimed to identify the artefacts in these data that may be of importance in many direc- tions. The analysis of "outliers" in details of the synthesis in the research studies of garnet-structured solid electrolytes was chosen as the object of demonstration of one of the practical applications of this methodology. Particular attention was paid to the choice of precursors. The thermodynamic data such as the heat of formation from the pure oxides as well as the results of drop solution calorimetry for simple oxides were involved as the descriptors of the studied systems. The overall performance of novelty/outlier detection of all types of outliers was characterized for the data described varying the complexity of description using ROC-AUC statistics and was assessed to be 0.71 – 0.72 using the Area-Under-Curve statistics. It was found that all “outlier” compounds related to those as the result of using the rare precursors in synthesis were successfully identified. The complementary regression analysis was performed to elucidate the relationship between the data diversity and the complexity of data description.

The activation of alkyl hydroperoxides to generate radicals is a key step in the initiation of radical polymerisations in many industrial applications, not least protective coatings. Cobalt soaps are highly effective catalysts under ambient conditions but viable alternatives based on less scarce catalysts are desirable, with especially iron and manganese catalysts showing potential. Manganese complexes of the ligand N,N',N"-trimethyl-1,4,7-triazacyclononane (tmtacn) are long established as catalysts for organic oxidations with H2O2, however their reactivity with alkyl hydroperoxides is less studied especially in low- or apolar solvents. Here we show that this family of complexes can be employed as catalysts for the decomposition of alkyl hydroperoxides in apolar solvents such as styrene/methyl methacrylate mixtures and resins based on styrene/bisphenol-A based diglycidyl ether bismethacrylate (BADGE-MA). The progress of alkene polymerisation in crosslinking resins is followed by Raman spectroscopy to establish its dependence on the oxidation state of the manganese catalyst used, as gelation time and onset of autoacceleration are of particular interest for many applications. We show, through reaction progress monitoring with UV/vis absorption and Raman spectroscopy, that the stability of the manganese complexes in the resin mixtures has a substantial effect on curing progress and that the oxidation state of the resting state of the catalyst is most likely Mn(II), in contrast to reactions with H2O2 as oxidant in which the oxidation state of the resting state of catalyst is Mn(III). Manganese complexes of tmtacn are shown to be capable initiators of alkene radical polymerisations, and their rich coordination and redox chemistry means that resin curing kinetics can potentially be tuned more readily than with cobalt soaps.

This qualitative research study explores the impact of training and skill development policies and practices on employee performance in the context of private banking in Bangladesh. The study follows a qualitative research design, utilizing purposive sampling to select 50 employees from various job roles and experience levels across different private banks in the country. Data is collected through in-depth interviews, allowing for a comprehensive understanding of employees’ experiences and perspectives regarding the training programs they underwent within the last 12 months. The demographic profile of the respondents highlights the gender, age group, job roles, experience levels, and types of training attended, presenting a diverse representation of the private banking workforce in Bangladesh. The findings reveal that employees generally had positive experiences with the training and skill development initiatives, perceiving them as valuable opportunities for professional growth and enhancing job performance. Participants praised the relevance and diversity of training programs, as well as the supportive learning environment. However, the study also identifies areas for improvement, including the need for more specialized and ongoing training opportunities, clearer career progression pathways, and transparency in the selection criteria. The research underscores the significance of practical application and continuous reinforcement of learned skills to sustain positive impacts on job performance. This study provides valuable insights for private banks in Bangladesh to enhance the effectiveness of their training and skill development policies. By addressing the specific needs and preferences of their employees, banks can foster a highly skilled and motivated workforce, contributing to improved organizational performance and employee satisfaction.
