The Role of Self-efficacy in Foreign Language Acquisition
Authors: Cedzich Artur 
Published: December 2024

Abstract
The aim of this article is to investigate the impact of self-efficacy on Foreign Language Acquisition in secondary school students following a relatively recent shift of focus in the field, as the learner’s needs, efforts and capacities have been placed at the centre of the learning process. Hence the need to address the existing research gap by proving that self-efficacy may be viewed as a significant indicator of foreign language proficiency. Apart from presenting the theoretical background, the article also reveals the empirical findings of the research carried out in a higher secondary school on 78 participants (N = 78). The study suggests that highly efficacious students receive the highest English mean grade, that they are competent foreign language users and are confident about their skills, and approach the FL learning progress more consistently, not being discouraged by taking risks in the foreign language acquisition context and confronting situations which cannot be foreseen. In stark contrast are learners scoring low levels of self-efficacy who are more likely to engage in procrastination, have a lower mean of English grades and are not eager to participate actively in the foreign language acquisition classroom. The article concludes with a number of implications and recommendations which may be implemented in the future teaching methodology, particularly indicating other research directions.

Published: December 2024

Abstract
Virtual synchronous generators (VSGs) incorporate virtual resistance (VR) in inverter control as a damping mechanism for oscillations that appear around the synchronous frequency due to interactions between the inverter impedance and the line impedance while operating in low inertia grids. Damping is critical for synchronization stability in the small-signal and large-signal disturbance scenarios to suppress oscillations that threaten system stability. While VR enhances stability in the steady state, it is shown that its conventional application affects the transient stability of VSGs by reducing the angle overshoot range in the dynamic behaviour of the power angle δ, illustrated using the power-angle (P − δ) and frequency-angle (δ̇− δ) curves. In this article, a novel damping mechanism to improve the transient stability of VSGs using VR to enhance the power angle dynamics is proposed. By using the concept of virtual point of common coupling, the virtual power of the internal VSG is introduced in the active power feedback during a voltage sag, providing an equivalent damping effect proportional to the VR applied. In this way, the negative effects of VR on transient stability are averted while VR is used to improve the power angle dynamics of conventional VSG. Simulations of different transient stability scenarios are carried out in MATLAB/Simulink to verify the proposed method.

Abstract
This study investigates the field emission characteristics of coated and uncoated graphite fiber tips under high vacuum conditions in the pressure range of 10–6 Pa. A 2 M Sodium hydroxide (NaOH) solution was used in the electrochemical etching procedure to produce an uncoated etched graphite fiber emitter with a diameter of 436.5 nm. An epoxy coating 2301 dielectric material with a thickness of 61 ± 1 nm was used to coat the fiber tip. Field-emitter emission micrographs, current stability, and current-voltage (I-V) characteristics were recorded. Murphy’s Good plots were used to examine and analyse the I-V characteristics. An orthodoxy test was performed to evaluate the Murphy Good plots. In the reported results, at low applied voltages, the uncoated graphite fiber emitter passed orthodoxy tests, and generated a steady current with 0.03 µA uncertainty. However, the coated graphite fiber emitter showed an increase in the applied voltage and threshold voltages but had no impact on the sample emission characteristics.

Published: December 2024

Abstract
In order to further improve the accuracy of the online monitoring spectra of partial discharge in gas insulated switchgear, a partial discharge distributed monitoring system is studied, and distributed sensors are used to simultaneously obtain ultra-high frequency electromagnetic wave signals. Based on the accumulated partial discharge spectra of each sensor, the smooth decoherence noise recognition algorithm is proposed on a long-term cumulative spectral pattern, which is used to analyse the correlation between the spectra of each sensor. Furthermore, a method for determining whether partial discharge is an internal signal is proposed, and its effectiveness is verified by practice, the results confirmed that the algorithm can avoid the misjudgement of partial discharge results caused by distributed sensor interference.
Viscoelastic Models of Tissues. Mathematical Background and Hysteresis Loops
Authors: Minárová Mária , Tvrdá Kataŕına , Zajícová Soňa 
Published: December 2024

Abstract
Human, animal, and plant tissues are typically viscoelastic, meaning their mechanical response lies between purely viscous and purely elastic behaviour. These tissues exhibit both viscous and elastic properties, modeled using viscoelastic frameworks. The mechanical behaviour of viscoelastic materials is determined by the relationship between stress σ and strain ε, referred to as the constitutive equation. In viscoelastic models, both stress and strain are functions of time. These models are often constructed using parallel or serial combinations of elementary components: Hookean elastic elements (H)and Newtonian viscous elements (N). The configurations formed through these combinations yield specific geometric equations which, when combined with physical equations, determine the corresponding global constitutive relations.
This study presents an analysis and theoretical results related to an approximate viscoelastic model for aponeurosis, specifically represented by the Burgers model.

Published: December 2024

Background & objectives
Biobanks are crucial for biomedical research, enabling new treatments and medical advancements. The biobank at the Madras Diabetes Research Foundation (MDRF) aims to gather, process, store, and distribute biospecimens to assist scientific studies.

Methods
This article details the profile of two cohorts: the Indian Council of Medical Research–India Diabetes (ICMR–INDIAB) study and the Registry of people with diabetes in India with young age at onset (ICMR–YDR). The ICMR–INDIAB study is the largest epidemiological study on diabetes in India, encompassing a nationally representative sample of individuals aged 20 yr and older from urban and rural areas in every State across the country. The ICMR–YDR is the first national-level, multicentric clinic-based registry focusing on youth-onset diabetes in India, aiming to understand the disease patterns and variations in youth-onset diabetes across different country regions.

Results
Key operations at the MDRF biobank include collecting and processing samples, where serum and whole blood samples are aliquoted and transferred through a cold chain to the central laboratory, and then stored in Siruseri (29 km from the capital city of Chennai, Tamil Nadu). Samples are barcoded, linked to subject information, and stored in freezers or liquid nitrogen (LN2) vessels, with inventory tracked via software for easy retrieval. A register records access to the biobank, ensuring sample integrity and compliance with regulatory requirements. The biobank adheres to the ICMR’s National Ethical Guidelines for Biomedical and Health Research involving human participants.

Interpretation & conclusions
The biobank enables the analysis of biomarkers in stored samples, aiding in scientifically sound decisions, treating patients, and potentially curing diabetes.
Pons herniation after skull base chondrosarcoma surgery: A rare complication after transclival endoscopic endonasal approach
Authors: Almeida Lucas Costa , da Silva Alice Caroline Alves , de Almeida Matheus Assis , Gonçalves Paulo Eduardo , Oliveira Arthur Maynart Pereira 
Published: December 2024

Background:
Intracranial chondrosarcomas are malignant tumors that most commonly affect the clivus region. For tumors in this location, the extended endoscopic endonasal approach could offer an alternative route. We present a case of pons herniation after this technique.

Case Description:
A 55-year-old female presented with a 6-month history of difficulty walking. The neurological evaluation showed asymmetric tetra paresis and involvement of the IX cranial nerve on the right side. Imaging exams showed a lesion at the upper clivus, with a possible diagnosis of chondrosarcoma. An extended transclival approach with partial resection and a multilayer closure were performed. The patient had a slight immediate improvement in muscle strength, and she was discharged home 5 days after surgery. Four weeks later, she evolved with worsening strength on the left side. A new image examination revealed an atypical protrusion of the pontine tissue through the bone defect at the opening of the clivus; a surgical revision was proposed, but the patient chose conservative management.

Conclusion:
Pontine herniation is a rare complication with no defined cause. The use of a rigid material for closure could reduce the chances of this complication, but futher studies are necessary to reinforce that hypothesis.

К ВОПРОСУ О СОЦИАЛЬНОЙ СТРУКТУРЕ ЧЕЧЕНЦЕВ-ОКОЧАН ТЕРСКОГО ГОРОДА В XVII В. (ПО МАТЕРИАЛАМ ДОКУМЕНТА 1640 г.)
Authors: Т.М. МАГОМАДОВА 
Published: December 2024

В статье рассматривается начало феодализации горской знати, роли Терского города в социально-экономической жизни края. Поставлена задача раскрыть хотя бы в общих чертах, опираясь на «Роспись» и ряд других источников, социальный статус самой престижной части окочан, их довольно активную деятельность в жизни Терского города в сношениях с Москвой; показано, как русская администрация осуществляла свою политику, привлекая членов феодальных семей. Опираясь на один из документов 1640 г., в статье представлены два феодальных клана чеченской диаспоры (окочан) – мурзы Кохостровы и первостепенные уздени Алеевы. Документы свидетельствуют, что жизнь ококов, втянутых в ритм городской разносторонней и разноэтнической жизни, мало чем отличалась от жизни других жителей города Терки и его слободок. Терские окочане принимали самое непосредственное участие во всех важных событиях, происходивших в городе Терки.
The article discusses the beginning of the feudalization of the mountain nobility, the role of the Terek city in the socio-economic life of the region. The author sets the task of revealing at least in general terms, based on the «Painting» and a number of other sources, the social status of the most prestigious part of the okokans, their rather active work in the life of the Terek city in relations with Moscow; to show how the Russian administration carried out its policy, attracting members of feudal families. Based on one of the documents of 1640, the article presents two feudal clans of the Chechen diaspora (okokans) – the Murzas Kokhostrovs and the primary Uzdens Aleevs. The documents indicate that the life of the okuks, drawn into the rhythm of the city's diverse and multi-ethnic life, was not much different from the life of other residents of Terka and its settlements. The Terek okokans took the most direct part in all the important events that took place in the city of Terka.
АТАЛЫЧЕСКИЕ И РОДСТВЕННЫЕ СВЯЗИ ГИРЕЕВ И КАБАРДИНСКОЙ ЗНАТИ В ПРОСТРАНСТВЕ РУССКО-КРЫМСКО-КАБАРДИНСКИХ ОТНОШЕНИЙ (СЕРЕДИНА ХVIII В.)

Published: December 2024

Статья посвящена изучению аталыческих и родственных связей между кабардинской знатью и различными ветвями династии Гиреев. Актуальные вопросы изучения подобных традиционных связей представлены на фоне случая, связанного с пребыванием в Кабарде в конце 1740-х – начале 1750-х гг. двух сыновей султана Арслан-Гирея (в 1748–1755 гг. – правящего крымского хана). К решению данного непростого вопроса оказались причастны Россия, Крымское ханство и Османская империя, причем соответствующие практики заняли в общей сложности не менее пяти лет. Описанный в статье такой случай рассмотрен на фоне как противоречий среди кабардинских элит, так и изменившегося после 1739 г. международного статуса Кабарды. Приведены новые данные о матримониальных связях одной из ветвей ханской династии Гиреев (султана Бахты-Гирея и его детей) с кабардинской знатью. Они, в свою очередь, вписаны автором в пространство традиционных социокультурных практик кабардинской знати с Крымским ханством, выгодных обеим сторонам и актуальных еще для середины XVIII в.
The article is devoted to the study of Atalyk’s (artificial kinship) and family relations between the Kabardian nobility and various branches of the Girey dynasty. Current exploring problems of these traditional connections are presented at the context of a case associated with the staying in Kabarda in the late 1740s – early 1750s two sons of Sultan Arslan-Girey (ruling Crimean Khan in 1748–1755). Russia, the Crimean Khanate and the Ottoman Empire participated in solution of this difficult case, and the relevant processes during five years at least. This described case is considered the background of both contradictions among the Kabardian elites and the international status of Kabarda that changed after 1739. New data are given on the matrimonial relations of one of the branches of the Khan dynasty of Girays (Sultan Bakhty-Giray and his children) with the Kabardian nobility. They are inscribed by the author in the space of traditional socio-cultural practices of the Kabardian nobility with the Crimean Khanate, beneficial to both sides and relevant for the middle of the XVIII century.
