Authors: Uličná Miriam , Fekete Roman , Juriga Martin , Kabát Juraj , Peciar Peter , Peciar Marian
Published: May 2023

The extrusion process is very popular in industry. Nowadays, extrusion is also closely associated with the 3D printing process, but this article is focused on extrusion, as a process that is mainly associated with spheronization. The extrusion product is shaped in such a way that it is suitable for the ongoing spheronization process. With this two-step extrusion-spheronization (E–S) process, it is possible to create pellets with controlled high sphericity, which are desired in tablet and capsule production due to their easily characterized (and controlled) dosage profile and good flow properties. During extrusion, it is important to monitor several parameters. This post is dedicated to one of them and that is the length of the die and its effect on the extrusion pressure as well as the effect on the extrudate surface quality.
CONSIDERATIONS ON THE FUTURE OF FEMINISM WITHIN THE POSTCOLONIAL AND POSTCOMMUNIST FRAMEWORK
Authors: MARINESCU Roxana-Elisabeta
Published: May 2023

This article presents some ideas on the future of feminism starting from the postcolonial/ postcommunist framework, based on similarities in the decolonisation and respectively transition periods in what regards approaches to gender and feminist practices, with a special interest in India and Romania. Some of these refer to belonging to the neoliberal paradigm and necessity to disrupt it, by strengthening the bottom-up work of the nongovernmental organisations, encouraging alternative knowledge systems and giving a voice to so-far silent members of society and non-human others, while focusing on a feminist ethic of care and using the COVID-19 pandemic as an opportunity for change.
SHAKTI AND LAKSHMI PRINCIPLES. EMPOWERING WOMEN IN INDIAN TRADITION
Authors: DAVID Cleopatra
Published: May 2023

The Indian traditions offer a very specific place in the society to women, and the religious practices give them certain responsibilities. Religion and common life are practically inseparable and the role models offered by the Hindu pantheon and sacred texts are to be reflected in the day to day activity. Shakti is the wife of Lord Sadashiva and the Mother of the Universe, while Lakshmi is the wife of Lord Vishnu, whose main characteristic is to bring prosperity. This article is approaching the role women play from the position of the Hindu tradition, overviewing Puranic and epic texts.
THE WOMEN FROM ALAPSUR IN GÖRAN TUNSTRÖM’S TRAVEL MEMOIR: THE DYNAMICS OF A REVERSED ALTERITY TECHNIQUE
Authors: BOBOC Raluca
Published: May 2023

Part of a larger project interrogating the strategies of different 20th century Scandinavian writers of reaching themselves by exploring anthropologic and geographic alterity during their travels, my article looks into the way that Göran Tunström’s Indian explorations, evoked in his travelogue “India – a winter journey”2, function as a catalyst of his personal destiny, reverberating in a singular form of artistic assumption. His inspiring explorations, at the same time geographical and interior, can even invite a phenomenological approach to alterity awareness, in which the portrait of the women from Alapsur plays an interesting role in reversing the functions of exotism and otherness.

Published: May 2023

As a country that maintains a presidential system of government, it is essential to concentrate on creating the framework and structure of government. This is closely tied to the establishment, evolution, and dissolution of such institutions. As a consequence, the President and the DPR will be capable of determining responsive and constitutional legal politics. This legal policy study focuses on how the growth and regulation of state ministries and state institutions were connected to the constitutional system's establishment, modification, and dissolution. Second, how can legal politics address this in a manner that seems to be constitutional? The objective of this study is to assess the arrangements pertaining to the formation, alteration, and dissolution of ministries and state institutions under the constitutional system in order to define the ideal political legislation.This research uses normative legal research methods with descriptive research specifications and is analyzed through library research and data analysis methods using juridical-qualitative. The results of the research and discussion in this study include: First, the arrangements regarding the formation, modification, and dissolution of ministries and state institutions do not yet have a clear legal basis so that the President as the holder of power, is irregular in issuing his policies. Second, the legal politics that was initiated wanted the Government and the DPR to be more synergized in terms of drafting legal considerations and normalizing them based on statutory regulations and principles in a presidential system of government.
Studies of Art of the Russian North at the State Russian Museum (1940—1970)
Authors: Tuminskaya Olga A.
Published: May 2023

The article reflects the actions of the central bodies of the country, overseeing the art activities in the area of study, preservation, conservation, restoration and promotion of Russian medieval art in the 1940s—1970s as an indicative system of a comprehensive integration approach.

The relevance of the work is to activate information on the formation of the rhetoric of the scientific community of the 1960s on the problem of studying monuments of Karelia and the Russian North, unknown until the specified time or registered, but did not have the status of a protected monument. By the exhibition “The results of the expeditions of the museums of the RSFSR on identification and collecting works of the Old Russian art” (1966), the consolidation of museum forces and capabilities of the governing bodies for the study of works of art in the complex of restoration, protection, scientific, educational potential increased.

The purpose of the article is to show the result of joint efforts of representatives of the RSFSR cultural departments and members of the museum community in the study, preservation, replenishment and presentation to the public of a number of materials of the culture of the Russian North. The author considers the coordinated actions that led to a landmark event — the reveal of a gap in the national art studies and its filling by means of expeditions, conservation of art monuments on the ground, restoration work in workshops in Moscow and Leningrad, exhibition activities, scientific discussions, participation in conferences and congresses, publication activity.

The events successfully implemented in the designated thematic plan — the study of the culture of the Russian North, determined the vector of development of the study of the art of icon painting of Novgorod and Moscow lands in the 1970s and 1980s. The author notes, that in the subsequent period, such large-scale and fruitful events were not held. The close-knit work of the Ministry of Culture of the Russian Federation, several departments of the State Russian Museum, and other museums of our country lasted throughout the period of 1940s — 1970s. Thus, this example can be regarded as the only indicator of a large-scale project in the history of Russian art, including scientific research, expeditions, restoration, educational activities and conferences.
Moscow in the Works of the “Big Book” Winners: Location, Subject, Image
Authors: Babicheva Maya E.
Published: May 2023

The paper considers the contribution of the works-laureates of the national literary prize “Big Book” to the formation of the “Moscow text” in the domestic literature of the 21st century. The relevance of the topic is determined by the most important role of the “Moscow text” in Russian culture in general and in the modern literary process in particular. The novelty of the research is in the specific consideration view of this cultural phenomenon: through the identification of characteristic features of the “Moscow text” in the works marked by the “Big Book”. The author presents review of the works of laureates, where Moscow is mentioned: popular science publications and works of art (mostly large, in several cases — medium epic form). The author shows that the place and role of Moscow in the text are always individual, correlated with the artistic tasks of each author and his personal perception of the city. The review starts with the collection of essays by the Moscovite scholar R.E.Rakhmatullin, dedicated, by definition of the author himself, to the metaphysics of Moscow. Then the author considers the novels by A.A. Kabakov, V.A. Zolotukha and L.A. Yuzefovich. Each of them has created an expressive image of the Russian capital in different periods of its existence. In a number of the works considered, Moscow primarily acts as life environment of the central character: lifelong (in L.E. Ulitskaya) or corresponding to a certain, more often initial period of biography (in M.S. Stepnova, M.P. Shishkin, etc.). In all these cases, the place of residence affects the fate of the character and, in turn, is characterized by the events of the plot. In a separate block, the article highlights the novelized biographies of Moscow writers, in which the capital is depicted as the centre of the literary life of the country. The paper shows both the role of each named writer in Moscow literary life and the reflection of Moscow life in his work. The author considers the ways of creating the image of the capital: from the description of urban landscapes to the reproduction of the “Moscow spirit” itself.
Philosophical Connotations of the Visual Images of Demonstration Materials of the Witcher Game Series
Authors: Ovchinnikov Vladimir M.
Published: May 2023

The article considers a complex of philosophical connotations, imagery and mythologies demonstrated by promotional materials (trailers) of game projects of the Witcher series. Embodying the concept of myth-making in the space of audio-visualized arts of the information revolution era, they appear as a special form of visualized text and a way of expressing narratives.

Actualizing the problem of positioning promotional materials of game projects, the author focuses on the fact that the trailer and teaser of the game project, as a special cinematic tool (which is demonstrated in the article), have a broad imagery, bearing the “philosophy” of the project, which gives the game action meaningfulness and expediency.

The cinematic trailer, while maintaining its function of product positioning, is not only an independent work, but also a carrier of diverse and numerous archetypal constructions that form the mass consciousness (now once again tending to mythologization in the conditions of rejection of the classical postulates of rationalism). This, in turn, determines the design of the phenomenon of “new mythology”, which actively instrumentalizes “classical plots and imagery”, thereby demonstrating continuity in the spiritual development of human civilization.

Taking into account the fact that the trailer is a kind of quintessence of ideas that characterizes the basic features of a certain cluster of the mass culture information space, they can be interpreted as a techno-artistic phenomenon having a hybrid nature, demonstrating the transformation of cultural production within the framework of historical discourse. Thus, it demonstrates the process of transformation of the complex of stereotypical mental constructions of social organization, which, in the conditions of globalization, takes the form of an international category.

According to the author, this phenomenon manifests itself in a significant increase in the degree of mythologization of the modern multicultural tradition, which, in turn, leads to the formation of a new cultural paradigm based on the concept of providentialism. It, in turn, acts as a tool for analyzing the historical and cultural process based on the instrumentalization of previous experience, which is changing in the global discourse.

Published: May 2023

In this study, we show the possibilities of developing a method for manufacturing electrically conductive copper patterns of arbitrary topology on various dielectric substrates by laser-induced synthesis from deep eutectic solvents. The possibility of printing on the industrially demanded dielectrics is shown, e.g., on polyimide, fiberglass plastic, and polytetrafluoroethylene (PTFE) substrates. The geometric and electrical properties of the resulting structures, as well as their composition, have been studied. The influence of the substrate material is shown to be substantial for the effective rate of formation of structures and their final properties.
Comparison of Polarization Energies from B3LYP and MP2 Parameterizations: Spherical Benzene and Anthracene Clusters
Authors: Testoff Thomas , Wang Lichang
Published: May 2023

To characterize polarization energies of organic small molecule based materials induced by aggregation, electronic structure calculations including density function theory (DFT) method become intractable when the size of the aggregates increases. A practical solution is to develop force field based on electronic structure calculations and molecular dynamics simulations. In this work, we performed B3LYP and MP2 calculations of neutral, cationic, and anionic benzene and anthracene and used these results to derive the state specific atomic polarizabilities (SSAPs) then to calculate the atomic dipole moments using QTAIM for better parameterization of the isotropic atomic polarizability for ionic systems. Ren’s atomic multipole parameterization method was also compared to a less computationally intensive B3LYP result and a grid quadrature method for multipole analysis in GDMA. Our results show that the trend in cluster size is the same for both parameterization methods, however, the magnitude of the apparent polarization energy is different for the bulk with a negatively charged carrier. B3LYP produces results closer to the experimental values for the positively charged carrier. The intramolecular electrostatic interactions of the negative charge carrier are a major depolarizing force. This relationship is reversed in the positive charge carrier.

Repeated injury of the lung epithelium is proposed to be the main driver of idiopathic pulmonary fibrosis (IPF). However, available therapies do not specifically target the epithelium and human models of fibrotic epithelial damage with suitability for drug discovery are lacking. We developed a model of the aberrant epithelial reprogramming observed in IPF using alveolar organoids derived from human-induced pluripotent stem cells stimulated with a cocktail of pro-fibrotic and inflammatory cytokines. Deconvolution of RNA-seq data of alveolar organoids indicated that the fibrosis cocktail rapidly increased the proportion of transitional cell types including theKRT5−/KRT17+aberrant basaloid phenotype recently identified in the lungs of IPF patients. We found that epithelial reprogramming and extracellular matrix (ECM) production persisted after removal of the fibrosis cocktail. We evaluated the effect of the two clinically approved compounds for IPF, nintedanib and pirfenidone, and found that they reduced the expression of ECM and pro-fibrotic mediators but did not completely reverse epithelial reprogramming. Thus, our system recapitulates key aspects of IPF and is a promising system for drug discovery.

This quantitative study aims to identify the relationship and influence of two independent variables which are acceptance and experience with satisfaction of e-learning as the dependent variable among pre-service teachers in Malaysia. The Technology Acceptance Model and Gratification Model were used as the basis to develop the research framework. A total of 616 respondents were involved in this study which employed questionnaires as the instrument. The descriptive and inferential analysis were carried out using statistical technique such as Pearson correlation and multiple regression. The Pearson correlation analysis showed a significant positive correlation between acceptance (r=0.817, p<0.01) and experience (r=0.879, p<0.01) with satisfaction. Despite of both independent variables significantly influenced the dependent variable, regression analysis showed that experience had more influence (β=0.525, p<0.01) on satisfaction of e-learning compare to acceptance (β=0.200, p<0.01). A comprehensive understanding of this study can help the policy makers, administrators and lecturer to improve the level of acceptance and experience of the pre-service teachers in order to enhance the satisfaction of e-learning among them in this country.

Inclusive education is a fundamental human right. However, students with learning disabilities are sometimes excluded from physical education. Virtual Reality (VR) and Augmented Reality (AR) technology are the type of immersive learning that have provided better learning experiences. Personalized learning makes its way towards inclusion in the classroom due to its effectiveness in individualized learning materials by considering the students' different attributes. Thus, this study aims to redesign a personalized and immersive trainer application to facilitate the learning process for the students with learning disabilities (SLD) in physical education using an Artificial Intelligence (AI) algorithm and immersive technologies. This qualitative study assesses ten teachers and 30 students from a special needs school via observation and interviews to design a personalized, immersive physical education learning app. Experts’ views and secondary data are also used as supplementary material for the construction of the app. From the interviews and observations done with the students and teachers, it can be concluded that the SLD can learn visually with suitable guidance from the teacher and trainer. The end output of this study is the design of a Personalized Learning System (PLS) that hopefully can be beneficial for developer and educator that wanted to design a good PLS for SLD. Educators and developers can use the result to create a suitable customized app for students with disabilities in learning physical education.

Fabrication routine of piezoelectric micromachined ultrasonic transducer (pMUT) requires complex and repetitive processes which consumes a lot of time and very costly. Deposition of Polydimethylsiloxane (PDMS) as an adhesive layer on silicon substrate has been done using spin coating. The role of this bonding is to adhere the Lead Zirconate Titanate (PZT) wafer. Another layer of PDMS is deposited on top of the PZT to manipulate device’s performance and also acting as protection layer. The thickness of the PDMS is controlled by the amount of current applied to to D.C. motor. The current used in this study is 1.0 A, 1.2 A and 1.4 A. The performance characteristic of pMUT is done by analysis the electrical properties. High resolution images of surface topography produced by Scanning Electron Microscopy with Energy Dispersive X-ray spectroscopy (SEM/EDX) and Atomic Force Microscopy (AFM) showed that the surface of the PDMS coating was smooth. It is better for wetted/submerged underwater application that require minimum hydrophobic characteristics of the acoustic matching layer. The results clearly proved that this wafer bonding process can simplified the fabrication routine of Piezoelectric Micromachined Ultrasonic Transducer (pMUT) without compromising the performance of the device.

In this study, we aimed to explore the current status and trends of research on LCS by doing a bibliometric analysis. Data on LCS were retrieved from the Web of Science database and a bibliometric analysis was conducted to measure the impact of publications, authors, organizations, and countries. Different software packages, including BiblioAnalytics, Bibliomaster, MS Excel, MS Access, VOSviewer, Biblioshiny, Power BI, and an online visualization platform were used for analysis and visualization in the present study. A total of 96 publications were included in the present bibliometric analysis. Authors “Lebbe C”, “Lorillon G”, “Mourah S”, and “Tazi A” received the highest number of citations, and the journal “Histopathology” received the highest number of citations. The outstanding organization was the Mayo Clinic in the USA with the highest number of 5 publications and the highest number of 175 citations. Japan and the USA were the outstanding countries that contributed to the research on LCS. Current literature on LCS is minimal, which stresses the need for more research productivity, especially within areas regarding diagnosis and immunohistochemical staining with CD markers for this pathology.

This quantitative retrospective study examines a non-probable convenience sample of 104 in-service mathematics and science teachers with the aim to understand their changes in attitudes toward the integration and use of information and communications technology (ICT) as a result of the COVID-19 pandemic. Data included a self-report questionnaire. The results indicate an increase in teachers’ knowledge regarding the e-learning environments available at their schools. The teachers revealed that before the pandemic, they mostly used computer tools to support struggling students or carry out basic calculations. However, during, because they had to plan distance learning environments, they introduced adaptive pedagogical use of ICT tools for all their students. The findings reveal that most teachers experienced difficulties emanating from lack of preparation time, technological knowledge, and/or technical conditions, thus suggesting that policymakers must decide how to provide adequate knowledge and technical support to allow teachers to successfully integrate computerized technologies into their teaching.

Published: May 2023

The urgency of studying the issues of the development of the circular economy in the agro-industrial complex is caused by the demand for national and international food security, the importance of preserving the environment in conditions of irrational environmental management, the need to harmonise the economic, ecological and social spheres of human activity involved in the production, sale and consumption of agricultural products. The purpose of the study is to justify a comprehensive approach to the implementation of the circular economy model in the agro-industrial complex, in the context of ensuring food independence, economic security of the country and achieving the goals of sustainable development. In the course of the research the general scientific methods of analysis and synthesis, statistical methods (comparison, analysis of absolute and relative values) and graphical methods were used in the evaluation of indicators of organic waste management of agricultural production, methods of a systematic approach – to justify a set of priority measures in the process of implementation of the model of circular economy in the agro-industrial complex. The information base for the research: legislative and regulatory acts; official materials of the State Statistical Service of Ukraine, the Ministry of Agrarian Policy and Food of Ukraine. Based on the results of the research, a comprehensive approach to the implementation of the principles of circular economy in the agro-industrial complex was formed. The key factor is an effective public policy capable of ensuring high rates of development of innovative resource-saving technologies and the introduction of circular business models. State activity includes the development of tax, credit and pricing policies to stimulate the implementation of circular economy principles. It is important to develop and approve strategic plans, legislative and regulatory acts that regulate activities in the field of circular economy and are adapted to the standards and norms of the legislation of the European Union. The activities of agricultural enterprises should be directed towards cooperation with scientific and educational institutions in order to solve the problems of introducing innovations and improving the qualifications of employees, technical and technological modernisation, establishing partnership relations with investors, raw material suppliers and local self-government bodies. Ultimately, the implementation of these measures will contribute to the growth of the competitiveness of the domestic agricultural sector, the growth of investment attractiveness and the preservation of the environment.

Published: May 2023

The study of the effectiveness of economic diplomacy has become a popular topic in the field of international economic relations. Recent trends are confirmed by a large number of academic studies focusing on the evaluation of the performance of diplomatic and consular offices abroad. This paper represents a new attempt to empirically examine the effectiveness of economic diplomacy using the example of a transition country, based on the activities of Ukrainian foreign representations. Over the last decade, this Eastern European state has experienced significant economic turbulence, political instability and a shift in the vector of foreign economic policy, which is the main impetus for the re-evaluation of its economic diplomacy. Using recent data on export flows, the authors apply a gravity model of trade to assess the impact of economic diplomacy on export activity. The results suggest that embassies are a more relevant means of promoting export flows to low- and middle-income countries.

The subject of the study is a complex of theoretical and methodological provisions and practical recommendations on increasing the effectiveness of the formation and use of the potential of enterprise management strategies through the creation and implementation of organizational and economic principles to increase their investment attractiveness. Currently, there is no objective method of managing the investment potential of an enterprise, which is capable of reliably reflecting possible problems of functioning and risks of investing funds in the enterprise. Existing methods of managing the investment potential of a company consider either an insufficient number of factors necessary for evaluation, or an excessive number of factors to be evaluated, as a result of which it is quite difficult for the investor to isolate the necessary information and make the right decision. For such enterprises the increase of investment attractiveness is possible only by qualitative changes in the management and production system, in particular by reorientation of the production process to the needs of the market, which will improve the image of the enterprises on the market and create new or develop existing competitive advantages. Methodology. The theoretical and methodological basis of the article consists of general scientific methods: comparison, dialectical development of economic systems, methodology of normative-legal and information-analytical support of the functioning of enterprises, formation and use of the strategy of potential management of the enterprise, creation and implementation of organizational and economic principles to increase their investment attractiveness. The research was based on the synthesis of social science theories, organizational systems theory and corporate finance theory. According to the system approach, the potential of the enterprise was considered as the potential of the financial system of the enterprise. The purpose of the article is the development of theoretical, methodological provisions and practical recommendations for the creation and implementation of the strategy of managing the financial potential of the enterprise in order to increase the investment attractiveness of the enterprise. Conclusion. The research carried out in the article consists in modernization and optimization of the considered strategies of financial potential management of the enterprise in order to increase the investment attractiveness of the enterprise, identification of an evaluation method that would meet the needs of investors, taking into account the factors significant for the assessment of the investment attractiveness of the enterprise, capable to objectively characterize its advantages and disadvantages and investment risks for investors.
