Vertically heated natural convection loop model
Authors: Bulatović Goran , Blunár Tadeáš , Bokes Peter 
Published: December 2024

Abstract
We present a comprehensive analytical model for laminar flow in a vertically heated rectangular convection loop, with applications to oil cooling in transformer systems. Starting from an integral equation, we apply a quasi-one-dimensional approach to derive equations for both loop velocities and temperature distributions. In this model, we account for temperature-dependent dynamic viscosity and introduce cooling at the loop top and in the fin. The analytical predictions are rigorously validated against finite volume method (FVM) simulations across different geometries and heat flux conditions, demonstrating strong agreement within a 2% discrepancy range for most parameters. This model provides a viable analytical alternative to computationally intensive simulations, offering insights into natural convection dynamics within closed-loop configurations.
Battery-less grid-forming type converter in an isolated AC microgrid
Authors: Teran Raul , Perez Javier , Beristain Jose , Valle Obed 
Published: December 2024

Abstract
Typically, in electrical microgrids (MG), the grid-forming type converter (GFRTC) includes a battery pack at its DC bus; thus, the GFRTC is modelled as a voltage source. In contrast with papers reported in recent literature, where the GFRTC with a battery pack is seen as a voltage source, this work proposes a GFRTC which can be used without a battery pack; with this, the GFRTC operates as a smart load to form the voltage at the point of common coupling (PCC); this is possible, as long as the smart load is supported by a grid-following type converter (GFLTC). This battery-less GFRTC proposal ensures a suitable operation of the isolated MG under linear and nonlinear load conditions. Also, this work proposes a control strategy for both GFRTC and GFLTC with a photovoltaic array. The test results showed that the control proposal allows to form a correct PCC voltage, ensuring a suitable operation of the isolated MG; this while the battery pack is: connected, disconnected, and reconnected to the GFRTC DC bus. This GFRTC proposal is very attractive for isolated MGs where the GFRTC battery pack must be replaced or reconfigured because of new demand profiles, without interrupting the isolated MG operation.

Abstract

Aim. The present paper aims to explore the challenges faced by employment agencies when recruiting Ukrainian refugee-background nurses (UKR-N) during the Ukrainian war refugee crisis in Poland, after the outbreak of war in February 2022.

Material and methods. Data were collected through semi-structured, in-depth interviews conducted in Poland with two representatives of one recruitment agency between May and July 2023. There were two female participants, one of Polish origin and one of Ukrainian origin. The data were analyzed using inductive thematic analysis. The ATLAS.ti 8 software was used for data management.

Results. Two themes were identifi ed: 1. Business-as-usual factors determining the eff ectiveness of international nurse recruitment and 2. Issues specifi c to the recruitment of Ukrainian refugee nurses. These two themes were further subdivided into six subthemes.

Conclusions. Recruitment agencies have an obligation to adopt a comprehensive approach to the recruitment of this group of applicants. In addition, the inappropriate recruitment of refugee-background nurses by recruitment agencies (RAs), which may lead to abuse and exploitation, violates fundamental human rights, and should be universally condemned and strongly discouraged.
Efficacy of Surgically Extracted Sperm in Assisted Reproductive Technology
Authors: Chadha Arzoo , Bakshi Rita 
Published: December 2024

Objectives
The objective of this study is to evaluate and compare the efficacy of various sperm extraction techniques used in Assisted Reproductive Technology (ART), focusing on sperm retrieval rates, fertilization rates, and clinical outcomes in patients undergoing fertility treatments.

Material and Methods
This retrospective observational study was conducted at RISAA IVF, Green Park, New Delhi, from January 2023 to January 2024. The study included male participants diagnosed with azoospermia, who underwent ART procedures such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). Sperm extraction techniques evaluated include percutaneous epididymal sperm aspiration (PESA), testicular sperm aspiration (TESA), and microdissection testicular sperm extraction (micro-TESE). Data were collected from electronic medical records, laboratory reports, and patient charts, focusing on demographic data, sperm retrieval rates, and clinical outcomes. Statistical analysis was performed using SPSS software, with significance set at P < 0.05.

Results
Surgical sperm retrieval was performed on 11 azoospermic patients. Viable sperm was successfully retrieved using PESA in 18.1% of the patients, while TESA and micro-TESE yielded successful retrievals in 63.6% and 18.1% of the cases, respectively. The overall pregnancy rate achieved through these procedures was 63.6%. No significant difference in pregnancy rates was observed between the different sperm retrieval techniques (P > 0.05).

Conclusion
The study highlights that PESA, TESA, and micro-TESE are effective sperm extraction techniques for azoospermic patients undergoing ART. The success in sperm retrieval and subsequent pregnancy outcomes underscores the importance of selecting the appropriate method based on individual patient conditions. These findings contribute to the evidence base for optimizing fertility treatments in patients with severe male factor infertility.
СТАНОВЛЕНИЕ (СОВЕТСКОЙ МОДЕЛИ) ОБРАЗОВАНИЯ В ЧЕЧЕНСКОЙ АВТОНОМНОЙ ОБЛАСТИ В 1920-е гг.

В статье рассматривается образование в Чеченской автономной области в 1920-е гг. Проблема ликвидации отсталости «национальных окраин» предусматривала образование на родном языке. Известно, что в 20-х гг. ХХ в. количество религиозных школ в Чечне превышало число светских школ и преподавали там одни и те же учителя. Борьба с арабизацией образования заставила Наркомпрос Горской АССР вернуться к выработке новой графической основы, применимой к языкам северокавказских народов. В Чеченской автономной области подготовке местных кадров придавали большое значение, лучших выпускников новых советских школ направляли в различные вузы и на рабфаки. Показано, что при строительстве школьного образования в ЧАО остро стояли проблемы подготовки учительских кадров, нехватки учителей, помещений, оборудования, учебников, отсутствия одежды и обуви у учащихся. Обучать горцев грамоте на их родном языке было важно и потому, что предстоял перевод всего делопроизводства в национальных областях на местные языки. Развитие социалистического строительства и связанные с этим задачи по подготовке кадров требовали скорейшего проведения всеобщего обязательного начального обучения. Введение всеобуча было сопряжено со строительством новых школ, увеличением числа учителей и повышением их квалификации, значительными капиталовложениями.
The article examines education in the Chechen Autonomous Region in the 1920s. The problem of eliminating the backwardness of the "national outskirts" provided for education in the native language. It is known that in the 20s of the twentieth century, the number of religious schools in Chechnya exceeded the number of secular schools and the same teachers taught there. The struggle against the Arabization of education forced the People's Commissariat of Education of the Mountainous ASSR to return to the development of a new graphical framework applicable to the languages of the North Caucasian peoples. In the Chechen Autonomous Region, great importance was attached to the training of local personnel, and the best graduates of the new Soviet schools were sent to various universities and labor departments. It is shown that the training of teachers, the lack of teachers, premises, equipment, textbooks, and often students could not attend school due to lack of clothes and shoes were acute during the construction of school education in the CHAO. It was also important to teach the highlanders to read and write in their native language because all office work had to be translated into national languages
КУЛЬТ ВОДЫ У НАРОДОВ ДАГЕСТАНА: ОТРАЖЕНИЕ В ФОЛЬКЛОРЕ, РИТУАЛЬНО-ОБРЯДОВЫХ КОМПЛЕКСАХ И РЕЛИГИОЗНЫХ ВЕРОВАНИЯХ

Published: December 2024

Статья посвящена представлениям народов Дагестана о воде в XIX – начале XX в. Богарное земледелие, напрямую зависимое от осадков, на большей части территории Дагестана и, соответственно, повышенный спрос на воду в период выполнения сельскохозяйственных работ вынуждали жителей горного края рационально расходовать имеющиеся водные ресурсы, бережно относиться к источникам воды. Почитание стихии воды народами Дагестана переросло в ее обожествление и олицетворение в мифологическом образе Матери воды. Целью данной работы является показать сквозь призму фольклора, обрядовых действий и религиозных верований отношение народов Дагестана к воде. Для достижения поставленной цели использованы труды по этнографии Дагестана и полевой материал авторов. В рамках исследования рассмотрены различные фольклорные жанры, комплекс ритуально-обрядовых действий и религиозных верований, связанных с водой. Исследование показало, что почитание воды и возведение её в ранг культа превратило отдаленные водные источники в места поклонения и проведения молебных мероприятий о ниспослании дождя. Вера в целебные и очистительные силы воды помогала при родах, «снятии» сглаза, выполнении магических ритуалов, а страх перед водной стихией породил различные запреты и веру в существование демонических духов, связанных с водой. Статья является обобщающим исследованием, основанным на авторских полевых материалах и литературе по данной проблеме.
The article is devoted to the ideas of the peoples of Dagestan about water in the XIX – early XX century. Rain-fed agriculture, directly dependent on precipitation, in most of the territory of Dagestan and, accordingly, increased demand for water during the period of agricultural work, forced residents of the mountainous region to rationally use available water resources and take care of water sources. The veneration of the element of water by the peoples of Dagestan has grown into its deification and personification in the mythological image of the Mother of Water. The purpose of this work is to show through the prism of folklore, ritual actions and religious beliefs the attitude of the peoples of Dagestan to water. To achieve this goal, the works on the ethnography of Dagestan and the field material of the authors were used. The study examines various folklore genres, a complex of ritual and ceremonial actions and religious beliefs related to water. The study showed that the veneration of water and its elevation to the rank of a cult turned remote water sources into places of worship and prayer events for the sending of rain. Belief in the healing and purifying powers of water helped with childbirth, "removing" the evil eye, performing magical rituals, and fear of the water element gave rise to various prohibitions and belief in the existence of demonic spirits associated with water. The article is a generalizing study based on the author's field materials and literature on this issue.
Alfabetización digital en la dimensión didáctica de la práctica docente, elementos para su análisis
Authors: George Reyes Carlos Enrique 
Published: December 2024

El concepto de alfabetización digital se ha delimitado tradicionalmente a aspectos técnicos relacionados con el uso de las TIC, lo anterior, si bien ha contribuido a generar procesos de formación en los que los docentes incrementan su conocimiento acerca de la utilización de dispositivos electrónicos y software, ha evitado aportar una noción holística respecto al manejo eficiente de estas herramientas en los procesos de lectura y escritura afines con la enseñanza y el aprendizaje. Este artículo hace una revisión teórica del tema estableciendo un vínculo con la dimensión didáctica de la práctica docente propuesta por Fierro, Fortoul y Rosas (2000) y retomado en el contexto de las tecnologías por George y Veytia, 2018). Con ello, se hace una propuesta que permite profundizar en la importancia de transformar el concepto para llevarlo al campo de lo que se hace con las tecnologías en el aula y lo que esto representa para la construcción de productos relacionados con la lecto-escritura actual.

Urticaria aguda
Authors: Maldonado Domínguez Edwin Daniel , Muñoz Estrada Víctor Fernando 
Published: December 2024

Background: Urticaria is characterized by the transient appearance of hives, angioedema, or both. Acute urticaria lasts less than 6 weeks. The origin is idiopathic in more than 50% of cases, and the most frequent triggers are infectious processes, drugs and foods.
Objective: Describe the origin, pathophysiology and treatment of patients with acute urticaria.
Methods: A bibliographic search of articles was carried out in PubMed, where the Mesh terms: “Urticaria”, “Angioedema” and “Antihistamines” were included and those with information related to acute urticaria were chosen, among those published from 2014 to 2023. In addition, the inclusion of some publications from previous years was considered, due to their relevance for this review.
Results: The initial search returned 135 articles, but only 104 were used for the final manuscript.
Conclusions: Acute urticaria is one of the most frequent reasons for consultation in the Allergology and Dermatology emergency services. Although there are multiple etiological factors, most cases are idiopathic, so it should not be overdiagnosed as an allergic reaction.
Keywords: Urticaria; Angioedema; Histamine Antagonists
CEILE: A Corpus of Free Indirect Style in Spanish—Structure, Development and Practical Application
Authors: Noelia Estévez-Rionegro  
Published: December 2024

Free indirect style is grammatically defined as a type of discourse typically used in literary texts which combines features of both direct and indirect style. Deictic elements corresponding to the narrator and to the characters overlap in free indirect style, with no specification as to whether the transcribed words refer to the former or the latter. Its unique aspects have caused some specialists to raise controversial issues in terms of characterising this structure. Part of the limitations of previous studies stem from the fact that they have been based on examples taken from specific works and authors, while more objective results could have been obtained if the principles of corpus linguistics had been relied upon, as the methodology allows research hypotheses to be based on meaningful samples of real language. However, the annotation of the existing language corpora for the study of the Spanish language prevents researchers from automatically retrieving samples of free indirect style. In order to bridge this gap, has been created a specific corpus of free indirect style called CEILE: Corpus de Estilo Indirecto Libre en Español (Corpus of Free Indirect Style in Spanish). CEILE has undergone three stages of development before reaching its current online version. This article describes how it has evolved over time, shows some possible uses and provides initial results obtained from its implementation, which significantly facilitates the analysis of this grammatical structure and its study in contrast to other reported speech procedures.
An Explicatory Overview of Human Communication and Sign Species
Authors: Bakil Ali Alwalss  
Published: December 2024

This paper is a descriptive, theoretical review of the relationship between human communication and sign species. This explicatory review attempts to look at communication from a semiotic perspective. Communication is perceived in this context as the interaction among individuals or groups; it can be verbal (spoken and/or written) or nonverbal (natural and/or artificial). The tremendous use of signs keeps the flow of delivering and receiving messages going. Admittedly, the natural omnipresence of signs and their artificial abundance block us from admiring their importance in directing our actions or shaping and re-shaping our schemata. One can think of how a driver’s performance would be affected when driving on an asphalted street and on a stony track. Apart from concentrating on the road (and driving) in both instances, the driver would certainly look for artificial signs more in the former, and for natural obstacles in the latter. Therefore, this paper explores the roles of signs in such conditions. First, it provides a brief account of the nature of communication and its rudimentary components: sender, receiver, code, message, medium, context, feedback, and interference. Second, verbal and nonverbal communication modes are discussed to form two main divisions of this article. These subsections draw an outline of the general frame of communication. The goal behind this is to lay the background for understanding the role of the numerous signs in delivering and receiving messages. After that, these are followed by an independent section on sign species and their types, viz.: symbols, icons, indexes, signals, symptoms, names, and numbers. The use of colours and emojis, as forms of informative communication, are reviewed as well. Finally, the last section discusses a few general features relevant to communication and signs. The importance of studying intercultural communication is briefly explored at the end of this overview.

Religion and Development in Postcolonial Tanzania: Contested and Negotiated Terrain (1961–2022)
Authors: Nyanto Salvatory S. 
Published: December 2024

Abstract
In the 1960s, when Tanzania embarked on people-centered development initiatives under ujamaa, leaders of the newly independent government warned all religious organizations that they should not mix religion with politics to build a secular state. Accordingly, ujamaa grew into what critics described as anti-religious, and public discussion of ujamaa in religious terms was forbidden. Yet government leaders used religious meetings as integral podia to clarify policy statements and to seek Muslim and Christian support for its socialist programs. The place of religion in development gained momentum after the decline of ujamaa as people sought alternative paths to the predicaments of the economic crisis. This article weaves through Tanzania’s postcolonial experience to show the place of religion in shaping development imperatives. It attempts to show how religion became a contested and negotiated terrain in the development discourses and more especially the rise of Pentecostalism as new contested terrain. Ultimately, the article seeks to demonstrate that an understanding of religion and development ought to consider the social context shaping the country’s development path.
BETROTHAL AND GENERAL DAMAGES FOR HUMILIATION: AN APPRAISAL ON HARMONISATION OF SHARI’AH AND CIVIL LAW
Authors: Azizah binti Mohd  , Nadhilah A. Kadir  , Badruddin Hj Ibrahim  
Published: December 2024

Betrothal is an agreement or a promise to marry. The Shari’ah and civil law recognise betrothal as a significant plan before and towards a marriage contract. Both laws also agree that in the event of a breach of betrothal, the party in default is liable to certain damages and compensation. Nevertheless, there are different principles as regards general damages for humiliation or embarrassment. This paper deals with betrothal and the legal effect of a breach of betrothal under the Shari’ah and civil law. The research is qualitative, adopting library research and content analysis. The research seeks to study the position of betrothal generally under both the Shari’ah and civil law and the effect of a breach of betrothal on the parties who are at fault. This paper further examines items claimable as compensation under both laws including general damages for humiliation. The paper further analyses certain points of laws on damages in breach of betrothal under both laws that are in harmony and differing. Finally, the paper highlights the possibility of harmonisation between the Shari’ah and civil law particularly on general damages of humiliation.
