Sistemas migratorios contemporáneos: organización y propiedades emergentes
Authors: Bologna Eduardo
Published: December 2024

En primer lugar, el trabajO discute la adecuación del uso del término "transnacionalismo" para describir las formas que coman algunas corrientes migratorias contemporáneas. ¡Se trata efectivamente de nuevas organizaciones socialessurgidas como resultado de los cambios en el contexto en que suceden las migraciones?; la globalización de los intercambios materiales y simbólicos de las últimas décadas ¿contribuyó a crear las condiciones para que los desplazamientos de población se generalicen?, o bien los flujos migratorios que presenciamos en la actualidad son equivalentes a los que sucedieron hasta la mitad del siglo :xx y lo que ha cambiado son sus consecuencias y nuestros medios para observarlos. En segundo lugar, se considera que las corrientes migratorias cambian a lo largo del tiempo,tanto en sus determinantes como sus características,volviéndose progresivamente más estables como organizaciones sociales espacialmente extendidas. En esta dirección, el trabajo propone un modelo descriptivo que busca dar cuenta de la complejidad del fenómeno. Tal modelo,construido desde una perspectiva sistémica, muestra los elementos que constituyen los flujos migratorios, su diversidad de formas y sus interacciones. A modo de ejemplo, se hace referencia a una propiedad emergente de los flujos: la circulación de remesas entre hogares migrantes, y se señalan los interrogantes que plantea esta particular forma de transferencia financiera internacional.
Do Facial Masks Impact Infants’ Joint Attention? A Within-Participant Laboratory Study
Authors: Wermelinger Stephanie , Mörsdorf Lea , Daum Moritz M. , Baldenweg Charlotte
Published: December 2024

During the COVID-19 pandemic, children were repeatedly confronted with people wearing facial masks. Little is known, however, about how this affected young children’s interactions with their caregivers. This preregistered experimental within-participants study explored whether facial masks influence young children’s initiation and response to joint attention. Using two structured tasks and one free-play task, we measured joint attention episodes in interactions of 12- to 15-month-old Swiss infants with one of their caregivers during the pandemic. In one experimental condition, the caregivers wore a facial mask; in the other, they did not. The results show no significant differences in infants’ joint attention between the two conditions. Infants may have interacted with their caregivers wearing facial masks enough previously not to be influenced by masks; alternatively, even with a partially covered face, a person provides enough information via eyes and other body parts that help infants to guide their attention.
The Influence of Social Media Platforms and Advertisements on Consumer Purchasing Behavior: A Study of Demographic Variations in Nepalese Youth
Authors: Chaudhary Huma Kumari
Published: December 2024

Background: The growing influence of social media platforms on consumer behavior, particularly in developing countries like Nepal, has been a subject of increasing interest. As social media usage rises, the impact of advertisements on purchasing decisions becomes a critical area of exploration, especially among the youth. This study seeks to understand how demographic factors, including age and gender, affect social media usage patterns and the influence of advertisements on purchasing behaviors.
Objective: The primary objective of this research is to examine the relationship between social media usage and consumer purchasing decisions, with a focus on the demographic characteristics of age and gender among Nepalese youth.
Methods: A cross-sectional survey was conducted with 123 respondents from different age groups, ranging from 16 to above 35 years. Descriptive data analysis was employed to assess demographic distributions and social media usage patterns, while a Chi-Square test was used to analyze the influence of gender on purchasing behavior due to social media advertisements. Respondents were asked about their preferred social media platforms, purchasing behaviors, and their views on the influence of social media advertisements.
Findings: The results revealed that Instagram is the most popular social media platform across all age groups, with a notable gender difference in platform preferences. Social media advertisements were found to influence purchasing behavior, with a majority of respondents either agreeing or being uncertain about their impact. The Chi-Square test showed no significant relationship between gender and the influence of social media advertisements on purchasing decisions. The majority of participants, particularly those aged 16-25, indicated that they were influenced by social media ads in their purchasing choices.
Conclusion: This study highlights the substantial impact of social media advertisements on the purchasing decisions of Nepalese youth, particularly among those aged 16-25. Gender did not appear to significantly influence the effectiveness of these advertisements. The findings suggest that social media platforms, especially Instagram and Facebook, play a crucial role in shaping consumer behavior, and advertisers should focus on these platforms to target younger audiences.
Novelty: This study provides valuable insights into the specific impact of social media advertisements on consumer behavior in Nepal, a developing market, and explores the role of demographic factors in shaping these behaviors.
Looks, personality, and everything in between: Understanding sexually attractive characteristics among cisgender and gender diverse individuals
Authors: Star Rebecca , Mulroy Maeve , Hunker Kate , Martínez Lizeth , Pukall Caroline
Published: December 2024

Sexual arousal, or feeling “turned on,” is experienced by many, yet an endless variety of factors influence how this response is manifested. Literature on the topic of sexually arousing partner characteristics is limited and focuses on primarily majority samples. The present mixed-methods study sought to answer the overarching question of what partner characteristics are considered sexually arousing by a diverse sample. Participants ( N = 344) were recruited through social media to complete open-ended questions inquiring about partner-related aspects of what turns them on sexually in the following domains: physical characteristics, personality traits, and nature of connection. Thematic analysis revealed nine themes and 28 subthemes overall, with few differences in frequency of endorsement between cisgender men and women or between gender diverse and cisgender participants. Quantitative analyses indicated differences in preferences for physical, though not for personality or connection characteristics among cisgender men and women and gender-diverse individuals. Results suggest broad conceptualizations of turn-ons, paving the way for future comprehensive perspectives inclusive of diverse samples.
The use of sexual humor in romantic relationships: Description, valence and association with sexual satisfaction
Authors: Lomore Christine D. , Weaver Angela D. , Lavoie Claire E.
Published: December 2024

Research shows that humour is related to relationship satisfaction, but little is known about couples’ use of sexual humour. The current study examined sexual humour use and its associations with relational humour, relationship satisfaction, and sexual satisfaction. Participants (adults in a romantic relationship of at least 4 months; N = 196) completed online measures of the frequency, nature, and perceptions of sexual humour use, relational humour use, relationship satisfaction, and sexual satisfaction, and they described an example of sexual humour their partner had used. Participants indicated that sexual humour was used at least occasionally with their partner. Examples of sexual humour suggest several common forms (e.g., inside jokes/rituals, physical humour, smoothing over awkward moments). Most participants perceived positive consequences of sexual humour, including increased comfort, fun, and closeness. More frequent use of positive relational humour (by self and partner) was associated with more frequent and more positively valenced sexual humour, whereas more frequent negative relational humour use by partner predicted lower relationship and sexual satisfaction. Finally, more positively valenced sexual humour predicted sexual satisfaction over and above relationship satisfaction and relational humour. Relationship and sexual humour are related to both relationship and sexual satisfaction. Sexual humour may help mitigate discomfort with potentially awkward situations and facilitate individual comfort as well as connection with a partner. The unique contribution of sexual humour to sexual satisfaction suggests it may play a modest but distinctive role in sexual well-being. Implications and future directions are discussed.
«WE ALREADY NEED TO RUN A MARATHON»: AN ANALYSIS OF SOCIAL WORK TRAINING EXPERIENCES DURING WARTIME
Authors: Baidarova Olha , Semigina Tetyana
Published: December 2024

The article presents the findings from a study on the training experience of the international NGO «International Leadership and Development Center» (ILDC) during full-scale war, specifically focusing on training activities for social workers and volunteers. The phenomenological approach (8 in-depth interviews were conducted) reveals various aspects, such as the impact of war on the mental well-being of both trainers and participants, and how stress factors, constant exposure to danger, and the chaotic environment influence the training process. The adaptation of training programs and trainers’ strategies to the new war-induced realities is explored.Key challenges faced by practitioners were identified, including an overwhelming increase in the number of clients alongside the expansion of client categories. New, unfamiliar groups appeared, such as military personnel and their families, wives and mothers of prisoners of war, freed captives and their relatives, women affected by conflict-related sexual violence, families of the deceased. The trainers and practitioners found themselves in a dual position, being both helpers and those affected by war. This created a need for professional support, especially in maintaining professional boundaries and avoiding secondary trauma.Another challenge was the need for social workers and volunteers to acquire new skills and competencies under stressful conditions – initially acute stress, followed by prolonged stress – which also impacted their cognitive abilities. The study highlighted that training must focus on maintaining the professional identity of social workers and adapt both its content and format to include a trauma-sensitive approach.The article concludes with specific recommendations for trainers and organizers of training programs during crises, suggesting strategies that could enhance the effectiveness of training in wartime conditions. It emphasizes the importance of trauma-awareness in designing training materials and the need for ongoing psychological support for practitioners, helping them navigate their dual roles.

Published: December 2024

Objectives: This study aimed to determine the perceptions of EFL teachers' challenges. In addition, this study investigated potential solutions to mitigate the challenges experienced by EFL teachers. Methods: This research took a qualitative design and, through a purposive sampling method, selected a total of six EFL teachers from three different private universities at a tertiary level. This study collected data through an in-depth interview. Interviews were then coded and analyzed based on thematic analysis in order to identify repeated patterns and insights for a comprehensive exploration of experiences and perspectives among participants. Findings: Most of the EFL teachers in Bangladesh do not consider AI-enhanced e-assessment an effective tool to assess students, and they are skeptical about its efficiency. They prefer pen-and-paper assessment to e-assessment. Infrastructural issues, lack of IT knowledge, lack of training in AI enhanced e-assessment, being unable to prevent e-cheating, plagiarism, and health hazards were some of the major challenges while conducting AI-enhanced e-assessment. Research implications: The study strongly underlines the demand for infrastructure development, rigorous training in using artificial intelligence tools, and effective policy measures to offset e-cheating and plagiarism.

Development and Evaluation of Anti-Acne Topical Gel Formulation Enriched with Herbal Extracts
Authors: Shende Madhukar , Khatri Ravi
Published: December 2024

Aim: This study aims to formulate and evaluate herbal gel preparations incorporating various extracts (aqueous, methanol, ethyl acetate, and petroleum ether) of Bougainvillea glabra to explore their potential as alternative treatments for acne, addressing the increasing resistance associated with conventional antimicrobial agents. Methodology: The herbal gel formulations (F1-F4) were prepared using Bougainvillea glabra extracts and subjected to a comprehensive evaluation, including physical characteristics, washability, skin irritation potential, spreadability, pH, viscosity, extrudability, swelling index, and accelerated stability, using standard protocols. Antibacterial efficacy was assessed by determining the minimum inhibitory concentration (MIC) against Escherichia coli and Bacillus subtilis, and the results were compared with a marketed herbal product and the standard drug Clindamycin. Results: Among the formulations, F2 exhibited optimal properties across the evaluated parameters. The extraction yield of Bougainvillea glabra was 11.21%. Antibacterial testing revealed that the aqueous extract exhibited minimal activity, while the methanol and ethyl acetate extracts showed moderate activity. The petroleum ether extract demonstrated the highest antibacterial efficacy among the extracts but remained less effective than Clindamycin. Formulations (F1-F4) mirrored the trends observed with the extracts but showed reduced antibacterial activity compared to the marketed herbal product. Conclusion: The herbal gel formulations containing Bougainvillea glabra extracts offer a potential alternative for acne treatment, with F2 showing the most promising results. While the petroleum ether extract demonstrated notable antibacterial activity, further optimization and in vivo studies are warranted to enhance their therapeutic potential and compare their efficacy with established products.
Vertical Mobility in Russian Politics
Authors: Kryshtanovskaya Olga V. , Lavrov Ivan A.
Published: December 2024

The article is devoted to the comprehension of the current vertical mobility channels in Russian politics. Not only the stability, functioning and development of the political system, but also the maintenance of the legitimacy of the ruling class depend on their parameters and efficiency. Based on long-term monitoring of the political elite recruitment, we analyzed the educational and professional experience of the current establishment members, as well as their geographical mobility. Total number of the studied group as of 01.01.2024 amounted to 885 people. The best prospects for an upward career trajectory are given to people born in Moscow, less often in St. Petersburg. People who grew up in the regions, to increase their chances, must move to 5 hub cities, from which their opportunities to enter the elite sharply increase. Our analysis of educational mobility also shows overconcentration: three universities prevail in the rating of elite universities – Lomonosov Moscow State University, St. Petersburg State University and MGIMO University. Professional upward flows are also characterized by low throughput: political career is promoted by three spheres of activity – housing, utilities and construction, finance and law. Overconcentration of upward mobility flows leads to negative consequences: the political system is perceived by citizens as unfair; the elite is largely delegitimized. This situation also hinders the development of meritocratic mechanisms selecting personnel for the establishment. To optimize the selection process, it is necessary to strengthen competition in selection, which will improve the quality of incorporated personnel and increase the ability of the system to withstand threats and challenges.
The Implications of Open Science Development: Risks of Increasing Inequality in Global Scientific Communication
Authors: Karikh Roman D.
Published: December 2024

The concept of open science, which is primarily a fight for free access to scientific knowledge, continues to gain support in the world. One of the goals of the concept is to solve the problems of developing countries and reduce inequality. This essay questions the feasibility of this goal. Presenting science as a world-system, the author describes its current structure in the format of academic colonialism, where the countries of the global North, located in the center of the world-system, dominate the countries of the global South, located closer to the periphery. The consequence of this model is epistemic injustice, which can be corrected in the context of open science. However, modern neoliberal trends in the form of platform capitalism do not allow us to cope with this problem within the framework of the concept in its current form, but only increase the risks of growing. The essay proposes possible solutions for the implementation of open science in Russia in an inclusive form based on the concept of bibliodiversity.

Artificial intelligence, augmented, virtual and mixed reality technologies in the educational process: development prospects in Ukraine
Authors: Fedorenko O.G. , Chala O.O.
Published: December 2024

The key areas and tasks of the development of artificial intelligence technologies are analyzed, in particular in the educational process, where the main goal is to train qualified personnel. In the context of general secondary education, the importance of developing students' digital literacy, integrating digital tools into the educational process, and training teachers to implement artificial intelligence technologies is highlighted.
The possibilities of using AI technologies in secondary education institutions are considered. Among them are the individualization of learning, automation of administrative and educational processes, the use of distance platforms, gamification of learning, as well as the introduction of virtual mentors, chatbots, VR, MR and AR technologies. Such tools not only increase the efficiency of the educational process, but also contribute to the formation of skills of the future. In particular, students develop social skills, the ability to interact with intelligent systems, master the basics of programming, machine learning principles, critical thinking and creativity.
In conditions of martial law, special attention is paid to the creation of interactive learning environments using artificial intelligence. They allow students to learn the material even with damaged infrastructure of educational institutions. Thus, the introduction of artificial intelligence technologies into education not only contributes to the modernization of the educational process, but also ensures the flexibility and resilience of the education system in the face of modern challenges.
Die Klassen in der Klasse. Zum Verhältnis von Materialismus und Intersektionalität in der qualitativen Sozialforschung
Authors: Kalkstein Fiona
Published: December 2024

Wer aktuell qualitativ forschen und dabei Klasse als analytische Kategorie berücksichtigen möchte, steht häufig schon wegen der nicht eindeutig bestimmten Verwendung des Begriffs vor vielen offenen Fragen: Klasse scheint relevant und Erfahrungen ihr entlang strukturiert, aber Klasse(n) – welche existieren, wie wirken sie, wo beginnen und wo enden sie? Der vorliegende Beitrag argumentiert, dass Klasse so schwer bestimmbar ist, da sie zwar wie andere Diskriminierungsformen auf verschiedenen Ebenen wirkt, aber im Gegensatz zu diesen unmittelbarer an ökonomische gesellschaftliche Struktur im Kapitalismus gebunden ist. Und dennoch ist Klasse nur intersektional adäquat abzubilden. Das materialistisch-intersektionale Mehrebenenmodell von Winker und Degele (2009) wird deswegen einerseits als Möglichkeit vorgestellt, Klasse auf den Ebenen der Struktur, der Repräsentation und des Subjekts analytisch zu durchdringen, anderseits wird auf die Leerstellen des Ansatzes eingegangen. Die Autorin argumentiert, dass ein materialistischer Subjekt- und Gesellschaftsbegriff den Schlüssel liefert, um die analytische Kategorie Klasse in der qualitativen Sozialforschung zu interpretieren. Abschließend werden die theoretischen Darstellungen forschungspraktisch konkretisiert und die Möglichkeiten ihrer Umsetzung anhand der Ansätze von Winker und Degele und der kritisch-psychologischen Subjektwissenschaft diskutiert.
Lehrer:innen und die Shoah – Gefühlserbschaften, Narrative und Vermittlungsanliegen
Authors: Lorenz-Sinai Friederike
Published: December 2024

Emotionale Bezüge und Geschichtsbewusstsein zur Shoah vermitteln sich zwischen den Generationen weiter und werden fortlaufend aktualisiert in institutionellen und diskursiven Kontexten der Gegenwartsgesellschaft. Bislang sind die intergenerationale Weitergabe von Narrationen und Gefühlserbschaften zur Shoah in Deutschland empirisch gezeigt, aber kaum in Bezug auf Pädagog:innen und ihre Vermittlungsrolle untersucht worden. Die im Artikel vorgestellte Studie erkundet diesen Zusammenhang anhand von Interviews und Gruppendiskussionen, die mit Lehrer:innen aus west- und ostdeutschen Bundesländern im Rahmen einer ethnografisch begleiteten Weiterbildung in einer Gedenkstätte in Israel geführt wurden. Rekonstruiert werden biografische Bezüge, Gefühlserbschaften und Narrationen von Lehrer:innen sowie ihre Vermittlungsanliegen für den Unterricht mit heutigen Schüler:innen. Die Befunde zeigen, wie Lehrer:innen nach eigenen Erzählungen, emotionalen Verbindungen zur Geschichte und Handlungsfähigkeit suchen und sich dabei in der Dissonanz zwischen der öffentlichen Erinnerungskultur und innerfamilialer (Nicht-)Verarbeitung der Shoah bewegen.

Kemampuan Kayu Secang (Caesalpinia sappan L.) dalam Menurunkan Bakteri Coliform pada Air Minum sebagai Upaya Penanggulangan Kasus Diare
Authors: Kasim Khiki Purnawati , Stientje Stientje , Haerani Haerani
Published: December 2024

Diare telah menjadi masalah kesehatan global akibat kurangnya akses ke air bersih dan aman. Menurut Organisasi Kesehatan Dunia (WHO), diare menyebabkan lebih dari 500.000 kematian anak-anak setiap tahun, terutama di negara-negara dengan akses sanitasi dan layanan kesehatan yang terbatas. Maka perlu adanya antisipasi melalui beberapa langkah yang kongkrit salah satunya dengan memanfaatkan sumber daya alam yang bermanfaat sebagai anti mikroba seperti kayu secang. Tujuan penelitian untuk mengetahui kemampuan kayu secang (Caesalpinia sappan L.) dalam menurunkan bakteri Coliform pada air minum sebagai upaya penanganan kasus diare dengan metode penelitian eksperimen quasi skala laboratorium dengan menggunakan 1 gr kayu secang dalam 1 liter air minum  selama 12 jam dengan variasi sampel yaitu air minum yang dimasak, air minum isi ulang dari 5 sumber, dan kontrol di analisa menggunakan uji Wilcoxon untuk  distribusi data tidak normal. Hasil penelitian menunjukkan bahwa penambahan kayu secang pada air minum yang dimasak dan air minum isi ulang dapat membunuh bakteri Coliform 100% yakni dari 240CFU/100 ml menjadi 0CFU/100ml dan uji statistik menunjukkan ada perbedaan signifikan (p value = 0,025) kemampuan kayu secang dalam menurunkan Coliform. Untuk kontrol tidak ada  perbedaan yang signifikan (p value = 1,000).  Penambahan kayu secang pada air minum yang dimasak dan air minum isi ulang mampu menurunkan bakteri coliform sesuai dengan syarat permenkes RI No. 2 Tahun 2023, sehingga disarankan kepada masyarakat untuk memanfaatkan kayu secang pada air minum sebagai upaya pencegahan diare.

Published: December 2024

Kesadahan air disebabkan oleh adanya logam-logam atau kation bervalensi dua, seperti kalsium (Ca) dan magnesium (Mg). Salah satu cara efektif untuk menurunkan kadar kesadahan adalah dengan memanfaatkan serbuk eceng gondok. Pada penelitian ini, serbuk eceng gondok diaktivasi menggunakan asam nitrat (HNO3) dan asam klorida (HCl). Eceng gondok mengandung gugus fungsi yang berperan sebagai gugus aktif dalam proses adsorpsi, sehingga mampu menangkap kation-kation penyebab kesadahan. Penelitian ini bersifat eksperimental dengan tujuan untuk menguji efektivitas penurunan kesadahan air menggunakan serbuk eceng gondok yang diaktivasi dengan HNO3 dan HCl dalam sistem kantong celup. Hasil penelitian menunjukkan bahwa serbuk eceng gondok yang diaktivasi dengan asam nitrat mampu menurunkan kadar kesadahan air dengan penurunan rata-rata sebesar 499,6 mg/l. Sementara itu, serbuk eceng gondok yang diaktivasi dengan asam klorida menurunkan kadar kesadahan air dengan rata-rata penurunan sebesar 451,3 mg/l. Kombinasi aktivasi asam nitrat dan asam klorida memberikan hasil penurunan rata-rata sebesar 510,05 mg/l. Kesimpulan dari penelitian ini adalah bahwa serbuk eceng gondok yang diaktivasi dengan asam klorida secara individu lebih efektif dibandingkan dengan aktivasi kombinasi asam nitrat dan asam klorida dalam menurunkan kesadahan air. Bagi masyarakat yang menghadapi masalah kesadahan pada air bersih, penggunaan serbuk eceng gondok yang teraktivasi dapat menjadi solusi alternatif yang menjanjikan. Potensi eceng gondok sebagai agen penurun kesadahan memberikan peluang baru dalam upaya penyediaan air bersih yang lebih terjangkau dan ramah lingkungan

This paper addresses the challenge of fine-grained alignment in Vision-and-Language Navigation (VLN) tasks, where robots navigate realistic 3D environments based on natural language instructions. Current approaches use contrastive learning to align language with visual trajectory sequences. Nevertheless, they encounter difficulties with fine-grained vision negatives. To enhance cross-modal embeddings, we introduce a novel Bayesian Optimization-based adversarial optimization framework for creating fine-grained contrastive vision samples. To validate the proposed methodology, we conduct a series of experiments to assess the effectiveness of the enriched embeddings on fine-grained vision negatives. We conduct experiments on two common VLN benchmarks R2R and REVERIE, experiments on the them demonstrate that these embeddings benefit navigation, and can lead to a promising performance enhancement.

On the Fractional Dynamics of Kinks in sine-Gordon Models

Published: December 2024

In the present work we explore the dynamics of single kinks, kink-anti-kink pairs and bound states in the prototypical fractional Klein-Gordon example of the sine-Gordon equation. In particular, we modify the order \(\beta\) of the temporal derivative to that of a Caputo fractional type and find that, for \(1 < \beta < 2\), this imposes a dissipative dynamical behavior on the coherent structures. We also examine the variation of a fractional Riesz order \(\alpha\) on the spatial derivative. Here, depending on whether this order is below or above the harmonic value \(\alpha = 2\), we find, respectively, monotonically attracting kinks, or non-monotonic and potentially attracting or repelling kinks, with a saddle equilibrium separating the two. Finally, we also explore the interplay of the two derivatives, when both Caputo temporal and Riesz spatial derivatives are involved.

Permasalahan dalam tesis ini, mengenai putusan risalah lelang oleh Pengadilan dapat digunakan sebagai dasar balik nama sertipikat di Kantor Badan Pertanahan Nasional/Agraria dan Tata Ruang dan upaya hukum penyelesaian pembatalan risalah lelang terhadap PTUN di Kantor BPN/ATR. Tesis ini, menggunakan metode penelitian hukum normatif dengan menganalisis data sekunder untuk mendapatkan hasil dan kesimpulan tentang putusan risalah lelang oleh Pengadilan dapat digunakan sebagai dasar balik nama sertipikat di Kantor BPN/ATR merupakan bentuk kepastian dan perlindungan hukum bagi pemenang lelang. Akan tetapi faktanya tidak dapat dibalik nama dikarenakan objek lelang telah diblokir oleh pihak pemenang lelang yang baru dengan objek lelang yang sama. Hal ini, berdasarkan gugatan pembatalan risalah lelang oleh pemenang lelang baru dengan bukti risalah lelang yang dikeluarkan oleh pihak KPKNL. Upaya hukum penyelesaian pembatalan risalah lelang terhadap PTUN di Kantor BPN/ATR merupakan bentuk perlindungan hukum bagi pemenang lama yang beritikad baik. Apabila, gugatan ke PTUN terhadap pembatalan risalah lelang ditolak atau tidak dikabulkan maka upaya hukum selanjutnya mengajukan gugatan PMH penerbitan risalah lelang baru oleh pemenang lelang baru ke Pengadilan Negeri.

Published: December 2024

Electromechanical processes in systems with frequency converters and electric machines, which are characterized by fluctuations in machine speeds, currents and voltages, are considered. In drives with rectifiers, capacitor filters, transistor inverters and asynchronous motors in some cases there are fluctuations of filter voltages and motor speeds, leading to emergency shutdown. In systems with thyristor frequency inverters with a DC link and synchronous machines at the start-up of machines in the zones of artificial commutation there are fluctuations of rotation frequencies and currents, which can also lead to emergency shutdown. A control algorithm based on the use of oscillations of constant capacitor voltages in transistor drives or excitation voltages of synchronous machines and the effect of these oscillations on the frequency of inverter control pulses is proposed.
