Authors: Rostaman Rostaman
Published: January 2025

The mushroom fly, or sciarid fly, Bradysia ocellaris Comstock, is a new pest species on the oyster mushroom in Indonesia. The insect pest could be controlled using insecticide treatments. However, information on insecticides that kill insects effectively was lacking. This research aimed to examine the usage of two insecticides for controlling sciarid larvae at the mushroom house. The parameter that was used was the emergence of adults. Several concentrations of cyromazine and cypermethrin were treated on sciarid larvae. The result showed that cyromazine was very effective in killing larvae of B. ocellaris. The number of emerging adults due to the insecticide was very low. I hope the cyromazine insecticide should be used to control sciarid flies in mushroom houses.

Published: January 2025

The aim of the study was to investigate the pattern of cognitive impairment and immune status of patients with MRI changes corresponding to CMA.

Material and methods. 65 patients with CMA according to the MRI criteria were examined. Depending on the degree of white matter hyperintensity (Fazekas scale), patients were divided into 2 groups: Group 1 — 40 patients with Fazekas stage 2; Group 2 — 25 patients with Fazekas stage 3. The control group consisted of 24 patients of the corresponding age category without MRI signs of CMA. Cognitive function was investigated using MoCA and additional tests to assess memory, executive function, attention, perception and praxis. Laboratory diagnostics included assessment of interleukin concentrations (IL), monocyte chemoattractant proteins (MCP-1/CCL2, MCP-2/CCL8, MCP-3/CCL-7, MCP-4/CCL13), macrophage inflammatory protein-1d (MIP-1d /CCL15), myeloid progenitor inhibitory factor — 1, (MPIF-1/CCL23) and tumor necrosis factor alpha (TNFα).

Results. Compared to the control group, patients in groups 1 and 2 showed more pronounced cognitive dysfunction, lacunar lesions, prevalence of hypertension and obesity, in the 2nd group of patients — prevalence of MRI — signs of CMA, decreased memory, perception and executive functions. Increased level of IL-16 in patients of both groups, higher concentrations of MCP-1/CCL2, MCP-2/CCL8, and MIP-1 d/CCL15, IL-6, IL-1b and TNFα were found in the 2nd group compared to the 1st and the control groups.

Conclusion. Progression of cerebral microangiopathy objectified by MRI data is accompanied by increasing cognitive deficit mainly in the mnestic and executive spheres. The results of the study allow us to consider increased IL-16 production as an indicator of CMA progression, and the expression of IL-1b, IL-6, TNFα, MCP-1/CCL2, MCP-2/ CCL8 and MIP-1d/CCL15 as biomarkers of athero- and angiogenesis in patients with severe cerebral microangiopathy.

Introduction. Neurophysiological methods, such as nerve conduction studies (NCS) and transcranial magnetic stimulation (TMS), as well as nerve ultrasound (US), can be used to examine patients with facial neuropathy. Currently, normative instrumental facial parameters exist only for adults and have not been studied in children. We have provided age-related reference values for NCS, TMS and nerve US of the facial nerve in healthy children.

Objective. The determination of age-specific neurophysiological and ultrasound parameters of the facial nerve in healthy children.

Material and methods. NCS, TMS, and nerve US were used to examine 65 children aged 5 to 18 without neurological symptoms. In addition, the results of facial NCS in healthy children under 5 (n = 24) were analyzed retrospectively. Statistical analysis was processed with an assessment of normality of distribution and the use of parametric or nonparametric tests.

Results. An age-related increase in the amplitude of M-wave was revealed for m. nasalis and m. orbicularis oculi, as well as in the amplitude, the latency and the area of motor evoked potentials (MEP) for m. frontalis, m. orbicularis, and m. nasalis. According to nerve US, there were no significant differences in diameter and depth of the facial nerve between children aged 5–12 and 12–18.

Conclusion. The obtained normative parameters for facial NCS, TMS, and nerve US in children of different age groups can be used in both everyday clinical and research practices.

Authors: Lia Riesta Dewi  , Azmi Polem  , Eki Furqon
Published: January 2025

Serang City has the authority to explore its revenue potential in various sectors to increase the Regional Original Income (PAD) in Serang City. PAD is a revenue receipt that exists in each region and is taken based on the statutory policies that have been set by the regional government, especially on regional taxes and regional levies. The fundamental change regarding sports venue levies between Law Number 1 of 2022 and Law Number 28 of 2009 lies in the scope of sports venues that can be subject to levies. Article 136 of Law Number 28 of 2009 states that only sports venues provided, owned, and/or managed by the regional government can be subject to levies. Article 88 of Law Number 1 of 2022 does not offer such limitations. This article aims to find out what the potential regional income is from the sports sector, especially in Serang City and what are the obstacles and barriers for the Serang City regional apparatus to obtain regional original income in the sports sector, using empirical legal research methods. The potential for local revenue owned by Serang City is one of them in the sports sector, in which the Serang City government has not been able to receive PAD. The obstacle that is of concern is the lack of entry of the new legal basis that is currently ratified by the central government regarding Sports as stated in Law Number 1 of 2022 concerning Financial Relations between the Central Government and Regional Governments, and Law Number 11 of 2022 concerning Sports into regional regulations, especially legal products belonging to the Serang City Regional Government

The purpose of this research is to find out more about land tenure without rights due to illegal acts. The research method used in this research is the empirical research method by taking a qualitative approach. The result of this research is that it is clear that both parties have agreed to exchange their land which has been outlined in the minutes. The agreement occurs when an agreement is reached between the parties making the agreement, so that the perpetrator's actions are included as unlawful acts. The elements that are fulfilled are the existence of an action that has been carried out by the perpetrator by continuing to control land that does not belong to him; the action must be against the law; and the action causes harm to the heirs. Furthermore, compensation for ownership of land rights due to unlawful acts must compensate the person whose fault caused the loss, either in the form of money or in the form of returning to the original state. The amount of compensation depends on the size of the claim filed by the injured party. The size of the compensation fee is measured by looking at the object of the dispute, the grace period, and the costs incurred in deliberation efforts. However, until now there is no good faith from the perpetrator to return or compensate for his actions

As a result, processes that typically require a whole laboratory can be integrated into a simple, micro-sized system. The Letter from Dr. Reverson F. Quero, Prof. José Alberto F. da Silva, and Prof. Dosil P. de Jesus shows how 3D printing has advanced the manufacturing of microfluidic devices.
As highlighted in the last BrJAC Editorial, the journal's impact factor increased from 0.7 to 1.1. This achievement not only reflects the publication of high-quality articles based on rigorous research methods but also considers the journal's growing visibility, which attracts more submissions worldwide. I am delighted to note that of the five Articles published in this issue, four come from abroad (two from India, one from Malaysia, and one from Morocco). These articles are based on thorough studies, utilizing a diverse range of techniques such as spectrophotometry, potentiometry, PCR analysis, scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction. This broad array of techniques clearly shows the increasing importance of analytical chemistry as a central science driving scientific advancements.
The growing interest of researchers worldwide in BrJAC demonstrates that our journal is an excellent vehicle for disseminating high-quality information across all aspects of analytical chemistry. I hope you enjoy this issue!
Factors Affecting Knowledge Transfer Interactions and Their Modelling in Higher Education (Based on a Hungarian Empirical Study)

Published: January 2025

There is no question that today's successful universities see themselves as bastions of knowledge trans-fer. The classic institutional role involves the transfer, development and preservation of knowledge. However, universities often fail to realise that several factors can influence the nature and frequency of knowledge transfer interactions between institutional citizens. The authors surveyed Hungary in 2021 and 2022 to analyse this, involving 552 students. The results show that students are more likely to seek professional help from teachers who provide them with up-to-date, practical knowledge. Furthermore, the authors present their own learning analytic model, using students' baseline data to predict the ex-tent to which students are willing to interact with instructors for knowledge transfer.
THE ROLE OF WOMEN IN MARITAL DYNAMICS: Hadis Interpretation of Amina Wadud’s Hermeneutic

Published: January 2025

Abstract: Misogynist views emerged from gender-insensitive reading of hadiths that talk about women, are often used as legitimacy in perpetuating injustice and even violence against women in the domestic sphere. The hadith misinterpreted as a justification for a husband's authority over his wife is the hadith regarding women's service to their husbands. In this regard, this article attempts to dig up in-depth information regarding the hadith, by taking a hermeneutic approach in re-understanding the hadith. This research aims to create a new meaning that is not misogynistic, by referring to the feminist hermeneutic method offered by Amina Wadud. This research uses library methods to explore relevant information through books and journals. The results of this research show that although the concept of submissive marriage was the social context in which this hadith was born, practically, the Prophet never showed an authoritative attitude towards his wife.

Keywords: Misogynist hadith, women's service, feminist hermeneutics, Amina Wadud, gender studies.

Исследована микроструктура покрытий, полученных методом холодного напыления на сталь Ст3 и алюминиевый сплав Д16АТ с применением нержавеющей и медной проволок соответственно. Для нанесения покрытий использовано новое разработанное устройство, отличающееся от существующих аналогов способом создания дополнительного слоя и массогабаритными характеристиками. Установлено, что толщина напыляемого слоя составляет 0,2 – 0,3 мм. Структура покрытия неоднородная, что обусловлено различием скоростей напыления мелкодисперсных компонентов, выдуваемых из сварочной дуги.

Published: January 2025

Изучены модельные сплавы на основе двойного сплава Ti – 10Al с добавками 1,2 % Mo, 1,3 % Nb, 3,2 % Sn, 4,3 % Zr. Определено влияние легирования на структуру, параметры решеток мартенсита, твердость по Роквеллу и контактный модуль упругости сплава в закаленном из b-области состоянии. Методом синхронного термического анализа установлена стадийность фазовых превращений (α′ → α + α2 + β, α2 → α, α + β → β) и развитие окисления в закаленных модельных сплавах при непрерывном нагреве до 1200 °C. Показано, что комплексное легирование сплава Ti – 10Al добавками Mo, Nb, Sn и Zr способствует: протеканию процессов распада α′-мартенсита при более высоких температурах; снижению температурного интервала α + β → β-превращения; сближению, вплоть до перекрытия, температурных интервалов α2 → α и α + β → β-превращений.
Current research status on multi-phase structure regulation in hot-work die steel via pre-martensitic phase transformation
Authors: Wang Zhenzhen Wang , Jiang Bin , Huang Zhimin
Published: January 2025

В обзоре обобщены современные достижения и основные методы регулирования многофазных структур в сталях, а также обсуждены потенциальные возможности применения для этой цели предмартенситного фазового превращения. Анализ факторов, влияющих на предмартенситное фазовое превращение, не только доказывает эффективность этого метода регулирования многофазной структуры, но и выявляет его существенные преимущества в улучшении микроструктуры и повышении механических свойств материала. Доказана роль такой технологии в ускорении превращения бейнита. Отдельно проанализирован синергетический эффект диффузии атомов углерода и движения дислокаций в процессе предмартенситного фазового превращения. Хотя управление многофазными структурами с помощью предмартенситного фазового превращения имеет большие перспективы, некоторые нерешенные проблемы в исследованиях все еще существуют. Обоснованы направления дальнейших исследований. Углубленное решение этих проблем имеет решающее значение не только для понимания сложности предмартенситного превращения, но и дает новые идеи для получения требуемой микроструктуры стали в промышленных приложениях.

Представлены результаты работы, выполненной методом корреляции цифровых изображений и состоящей из трех частей: I. Формирование зародыша полосы и очагов деформации. II. Деформация на площадке текучести. III. Потеря пластичности стали при деформационном старении. Все части отражают решение общей задачи: установить основные факторы на мезо/макроуровне, ответственные за снижение пластичности сталей с эффектом деформационного старения на площадке текучести, линейной и степенной стадиях, а также в целом при растяжении образцов до уровня предела прочности. В части I изучена эволюция структурно-деформационной картины на ниспадающей ветви зуба текучести и в начале площадки текучести. В части II приведены данные о ходе пластической деформации на площадке текучести. В части III описаны особенности деформации на линейной и степенной стадиях растяжения, а также проведен анализ результатов всей работы. В части I, приведенной в настоящем номере журнала, изучены механические свойства и характеристики деформации стали 08Г2Б, проявляющей различную величину эффекта деформационного старения после термической обработки по режимам: отжиг при 250 °C, 30 мин с охлаждением на воздухе и отжиг при 680 °C, 30 мин с охлаждением в воде. Показано, что, несмотря на значительно различающиеся прочностные и пластические свойства стали после разных режимов обработки, она деформируется на площадке текучести по одинаковому механизму Людерса. Механизм включает возникновение и рост зародышевых центров, зародышей полос локализованной деформации, их пересечение, а в середине образца — с образованием очаговых центров. Рассмотрены параметры, определяющие напряжение старта источников, испускающих дислокации плоских серий, которые формируют растущий зародыш полосы, что позволило объяснить влияние различных факторов на нижний и верхний пределы текучести в районе зуба. Проанализированы условия реализации полосового механизма деформации и его сочетание с рассредоточенной деформацией, при которой дислокации одновременно распространяются в различных системах скольжения.

Virtual reality (VR) has fundamentally changed how students interact with their subjects and learn because it offers an immersive learning environment. This qualitative study aims at exploring Omani English as a foreign language (EFL) teachers’ perceptions of using VR. It employed semi-structured interviews with 20 schoolteachers working in Al-Dhahira Educational Governorate in Oman, 10 females and 10 males. The findings revealed positive perceptions towards VR integration into education. However, the study found key challenges hindering the implementation of VR in education, including time constraints, technological barriers, financial concerns, the need for professional training, content creation challenges, and the necessity for students to acclimate to VR technology. Further, it showed that the primary concerns related to VR focus on cultural considerations, hacking, privacy, data security, and potential addiction. It also illustrated teachers’ main recommendations of providing sufficient infrastructure, institutional support, and continuous research on such technology. This research fills a gap in literature regarding the effective integration of VR into the Omani educational system. By tackling the specific challenges related to this context, it provides valuable implications and recommendations for Omani policymakers and educators to introduce VR for students in public schools in Oman.
