Applicability of multi-agent control for virtual inertia modes in a wind power plant
Authors: Astapov V. Yu.
Published: January 2024

This work presents a literature review devoted to increasing the efficiency and quality of managing wind power plants. The analysis focuses on mitigating the adverse effects of wind turbines on the power system and providing system services, such as primary frequency regulation. Nearly 150 scientific publications and reviews, selected from various scientific sources (such as IEEE, Web of Science and Scopus) by the keywords, including “wind power station”, “wind turbine”, “multi-agent control”, “virtual inertia”, “microgrid”, “virtual power plant”, and “frequency control”, were evaluated.

A systematic review methodology of specialised sources was applied, which offers a defined structure for this field of research by categorising articles. The study emphasises the urgency of developing technologies to increase the regulation capacity of a wind power plant, since the low inertia of renewable energy sources leads to a decrease in the stability of power systems, a significant proportion of which accounts for wind power plants. It follows from the literature review that one of the means to increase the stability of such power systems is the creation of virtual inertia for wind power plants. However, due to the limited capacity and control capabilities of each individual wind turbine, the efficiency of introduced virtual inertia may be insufficient, when implemented for individual units. Moreover, it is shown that uncoordinated control can affect the stability of the system. In this review, the specific sources considering coordinated multi-agent control of the virtual inertia for several wind turbines (wind power plants) were analysed. The review concludes that the proposed approach is currently understudied, while the outlined theses can be confirmed by developing the necessary algorithms and analysing the results.
Allocation of power losses and energy in the distribution network

Published: January 2024

The goal is to determine methods for calculating power losses in a three-phase four-wire low voltage distribution network using measurements of a balance smart meter and consumer smart meters, and to establish the factors influencing the power losses and their allocation among individual network wires, loads, and consumers. The study involved examining three methods for determining power losses for  current measurement snapshot. The first method suggests calculating losses as the difference between the power supplied to the network and the total power consumed. The second method calculates power losses using the contribution method. The third method, which in addition to measurement information requires knowledge of the topology and parameters of the network components, determines power losses based on the results of the state estimation method.  The research proposes an algorithm for transition from a four-wire distribution network modeling to a three-wire one. The algorithm allocates power losses of the neutral wire among the phase wires. The findings indicate that the negative losses in the network with unbalanced phase loads are caused by the presence at the nodes of the least loaded phase of higher voltage than the voltage at the power supply node. The reason for higher losses in phases with minimal load is the uneven allocation of loads in the phases. In addition, the study reveals that the power loss values obtained by the contribution method, i.e. directly from the measurements of smart meters, are closer to the losses determined from the readings of the balance meter and consumer meters, compared to the losses found from the state estimation results. The considered methods for calculation and allocation of power losses are illustrated by an example of a real-world distribution network equipped with smart meters.  The paper demonstrates the examples of allocating total power losses between phase wires and a neutral wire, among phase wires only, and between total loads at phase nodes and individual consumers in phases.
Comparison of methods for enhancing gold recovery from double refractory concentrates using the technology of autoclave oxidation
Authors: Petrov G. V. , Gordeev D. V. , Bekirova V. R.
Published: January 2024

The study aims to investigate the most efficient method for significant minimization of the impact of organic carbon on gold recovery from double refractory raw materials. We tested three double refractory gold-sulfide concentrates from different deposits with the content of gold from 23.5 to 40.9 g/t and total carbon from 1.2 to 9.5 wt %. Thermal treatment was carried out in a tubular rotary furnace that provided permanent temperature setting and rotation speed in the reactor. The initial concentrate was grinded as pulp in a Fritsch planetary mono mill Pulverisette 6. Autoclave oxidation was performed in Premex and Büchi titanium autoclaves. The technology of autoclave oxidation with the addition of a secondary oxidizer was found to be the most efficient, since it can increase gold recovery up to 97%. Another technology – hightemperature autoclave oxidation – also proved high performance; however, a significant increase in the residence time of the material in the autoclave (up to 120 min) at elevated temperatures is required to achieve this performance. According to the results, thermal treatment in general can provide a small increase in gold recovery (up to 4%). Due to this, it can be used as an additional processing with other methods analyzed in this article rather than as a self-sufficient technological solution. The studies revealed that the preliminary thermal treatment of concentrates entering autoclave oxidation shows a positive effect; high-temperature autoclave oxidation of concentrates with different carbon content provides high gold recovery for high-carbon concentrates; the use of a secondary oxidizer (in the form of nitric acid) also benefits the gold recovery. The high efficiency of the technology for concentrates with different carbon content allows us to recommend it for further research.

Published: January 2024

The Matsubara Green’s function formalism stands as a powerful technique for computing the thermodynamic characteristics of interacting quantum many-particle systems at finite temperatures. In this manuscript, our focus centers on introducing MatsubaraFunctions.jl, a Julia library that implements data structures for generalized n-point Green’s functions on Matsubara frequency grids. The package’s architecture prioritizes user-friendliness without compromising the development of efficient solvers for quantum field theories in equilibrium. Following a comprehensive introduction of the fundamental types, we delve into a thorough examination of key facets of the interface. This encompasses avenues for accessing Green’s functions, techniques for extrapolation and interpolation, as well as the incorporation of symmetries and a variety of parallelization strategies. Examples of increasing complexity serve to demonstrate the practical utility of the library, supplemented by discussions on strategies for sidestepping impediments to optimal performance.
From Vision Correction to Drug Delivery: Unraveling the Potential of Therapeutic Contact Lens
Authors: Saini Ankush , Sharma Mohit , Singh Indu , Swami Rajan
Published: January 2024

Contact lenses (CLs) have become an essential tool in ocular drug delivery, providing
effective treatment options for specific eye conditions. In recent advancements, Therapeutic CLs
(TCLs) have emerged as a promising approach for maintaining therapeutic drug concentrations on
the eye surface. TCLs offer unique attributes, including prolonged wear and a remarkable ability to
enhance the bioavailability of loaded medications by more than 50%, thus gaining widespread usage.
They have proven beneficial in pain management, medication administration, corneal healing, and
protection. To achieve sustained drug delivery from TCLs, researchers are exploring diverse systems,
such as polymeric nanoparticulate systems, lipidic systems, and the incorporation of agents like vitamin
E or rate-limiting polymers. However, despite breakthrough successes, certain challenges persist,
including ensuring drug stability during processing and manufacturing, controlling release kinetics,
and biomaterial interaction, reducing protein adhesion, and addressing drug release during packaging
and storage etc. While TCLs have shown overall success in treating corneal and ocular surface
disorders, careful consideration of potential issues and contraindications is vital. This review offers
an insightful perspective on the critical aspects that need to be addressed regarding TCLs, with a
specific emphasis on their advantages and limitations.

Identification of Breast Cancer Immune-related Prognostic Characteristics in Tumor Microenvironment
Authors: Tang Zhenning , Li Ling , Huang Xiaoying , Zhao Yinbing , Liu Qingyuan , Zhang Chaolin
Published: January 2024

Background:

Accumulated evidence suggest that tumor microenvironment (TME)
plays a crucial role in breast cancer (BRCA) progression and therapeutic effects.

Objective:

This study aimed to characterize immune-related BRCA subtypes in TME, and identify
genes with prognostic value.

Methods:

RNA sequencing profiles with corresponding clinical data from The Cancer Genome
Atlas (TCGA) database of BRCA patients were downloaded to evaluate immune infiltration
using the single-sample gene set enrichment (ssGAEA) algorithm. Further, BRCA was clustered
according to immune infiltration status by consensus clustering analysis. Using Venn
analysis, differentially expressed genes (DEGs) were overlapped to obtain candidate genes.
Kaplan–Meier (K-M) analysis was performed to identify prognostic genes, and the results were
verified in the GEO and METABRIC datasets. RT-qPCR was conducted to detect the mRNA
expression of prognostic genes.

Results:

In the TCGA database, 3 immune-related BRCA subtypes were identified [cluster1
(C1), cluster2 (C2), and cluster3 (C2)]. The C2 subtype had better overall survival (OS) compared
to the C1 subtype. Higher levels of immune markers and checkpoint protein were found
in the C2 subtype than in others. By combining DEGs between BRCA and normal tissues, with
the C1 and C2 subtypes associated with different OS, 25 BRCA candidate genes were identified.
Among these, 8 genes were identified as prognostic genes for BRCA. RT-qPCR showed
that the expressions of 2 genes were significantly elevated in BRCA tissues, while that of other
genes were decreased.

Conclusion:

Three BRCA subtypes were identified with the immune index, which may help
design advanced treatment of BRCA. The data code used for the analysis in this article was
available on GitHub (https://github.com/tangzhn/BRCA1.git).

Authors: Hu Jiali , Zeng Lei , Hu Ronghuan , Gong Dan , Liu Mengmeng , Ding Jianwu
Published: January 2024

Background:

Recent studies reported that terminal nucleotidyltransferase 5A
(TENT5A) is highly expressed in glioblastoma and associated with poor prognosis. In this
work, we aim to specify the expression level of TENT5A in different grades of glioma and explore
its role in glioma progression.

Methods:

GEPIA online tools were used to perform the bioinformatic analysis. qRT-PCR,
Western blot, and Immunohistochemistry were performed in glioma cells or tissues. Furthermore,
CCK8, colony formation, transwell, flow cytometry and scratch assays were performed.

Results:

TENT5A was highly expressed in glioma and its level was associated with the pathological
grade of glioma. Knockdown of TENT5A suppressed cell proliferation, colony formation
ability, cell invasion and migration. Overexpression of TENT5A was lethal to the glioma
cells.

Conclusion:

Our data showed that the expression of TENT5A is associated with the pathological
grade of glioma. Knockdown of TENT5A decreased the ability of proliferation, invasion and
migration of glioma cells. High levels of TENT5A in glioma cells are lethal. Therefore,
TENT5A could be a new target for glioma treatment.

background:

The prevalence of cancer is around the world and is identified as a multifarious ailment. Amongst the most common reasons of cancer in the world is oxidative stress, and this can be overcome by taking herbal plant wheatgrass in any form. As colloidal carriers with particle sizes of 50-1,000 nm, Solid Lipid Nanoparticles (SLNs) combine the benefits of liposomes, emulsions, and other colloidal systems to deliver drugs at their targets.

Aim and Objective:

The aim of the present work is to formulate wheatgrass extract-loaded solid lipid
nanoparticles using Box-Behnken design and to investigate the effect of formulation variables.

Methods:

Using the hot homogenisation method, the current work plan aimed to develop wheatgrassfilled
chitosan solid lipid nanoparticles by means of a Box-Behnken design. This study investigated
the effect of three formulation variables on particle size and entrapment efficiency, namely the sodium
alginate concentration, the chitosan concentration, and the sonication time. Extraction of wheatgrass
was done in a soxhlet extractor, using methanolic extract. Furthermore, the authors have examined
recent patents associated with wheatgrass to enhance their comprehension of this herbal plant.

Results:

The hot homogenisation technique was used to prepare Triticum aestivum extract loaded
with solid lipid nanoparticles (SLNs). For BBD, all formulations were analysed for particle size,
which ranged from 394.4 to 911.2 nm, and for polydispersity index, which ranged from 0.527 to 1.0.
Batch code BB SLN-8 was found to be the finest suitable because of a maximum loading capacity of
58.23 ±0.11 % (w/w), maximum entrapment efficiency of 55.12±0.17 % (w/w), and minimum particle
size of 394.4nm by using sodium alginate as a surface stabiliser at sonication time ~ 10 min and
having maximum percentage yield of 49.87%. During characterisation studies and MCF-6 cell line
studies, it was found that wheatgrass has antioxidant potential and is potent against breast cancer.

Venom Using Peptide Library
Authors: Rami Abbas , Behdani Mahdi , Kazemi-Lomedasht Fatemeh
Published: January 2024

Background:

Envenomation with Odontobuthus doriae scorpion results in pain at the bite
site, inflammation, necrosis, and neurotoxicity. Administration of anti-scorpion antiserum prepared
from immunized horses is the main therapy for envenomation. However, in some cases, anaphylactic
shock related to antiserum administration limits its use. Therefore, the identification of the venom
component and the development of a specific neutralizing agent is very important. Identification of
linear epitopes of O. doriae using a peptide-displayed phage library (Ph.D.TM -7) was the main aim
of the current study.

Methods:

Three rounds of biopanning were performed on immobilized immunoglobulins (IgGs) isolated from the sera of an immunized horse. The biopanning process was checked
by polyclonal phage enzyme-linked immunosorbent assay (ELISA). Forty blue phage colonies were
randomly selected from the third round of biopanning, amplified, DNA extracted and submitted for
sequencing.

Results:

Polyclonal phage ELISA results confirmed the progress of the biopanning process. The antigens involved in stimulating the horse's immune system were identified, namely sodium
channel toxin, potassium channel toxin, chloride channel toxin, cell protein, venom protein, and antimicrobial peptide.

Conclusion:

Identified epitopes promise further research to develop novel diagnostic or therapies against O. doriae envenomation.

The purpose of this study was to determine the effectiveness of using hybrid learning with augmented reality to improve the high-level thinking skills of junior high school students in the area of geometry. In addition, the effects of hybrid learning with augmented reality on students' motivation to study geometry are also examined. This research technique uses a sequential mixed methods approach, combining quantitative and qualitative methods in sequence. Quantitative approaches were used in the first phase to collect quantifiable data, and qualitative methods were used in the second phase to explore the results of the first phase. A two-group pretest-posttest design is the quantitative research method used. In order to establish an experimental class and a control class, the research sample was selected using the cluster random sampling method. In addition, while the control class uses hybrid learning without augmented reality, the experimental class takes advantage of it. Interviews and observation sheets are used in the qualitative design dimensions. The quantitative part of the data shows that students who receive hybrid learning with augmented reality have higher order thinking skills in terms of ideas in geometry than students who receive hybrid learning without augmented reality. The HOTS N-Gain scores from hybrid learning with augmented reality are 0.62, while the HOTS N-Gain scores from hybrid learning without augmented reality are 0.43, both of which support this conclusion. In addition, according to the findings in the qualitative dimension, students are more motivated and engaged in learning when using augmented reality applications than when they are not. These qualitative findings suggest that augmented reality software can be successfully used as a teaching tool for geometry topics.

This study aims to measure the preventive effect of the silver, Zn oxide nanoparticles, and Camellia sinensis L. (black tea) on liver toxicity caused by the paracetamol drug. The Nanomaterials, with a practical size range of 33–40nm, black tea was extracted by Soxhlet apparatus using methanol alcohol at a concentration (80%); design in this study, 60 adult male rats weighing between 195 and 330 g and aged 11 to 14 weeks were used. They were kept in a relatively regulated setting with a temperature of 25Co at the University of Karbala’s animal facility. They received food. There were eight rat group divisions. G1: just received saline solution (0,85%) as the control. G2: 250 milligrams of black tea and 250 milligrams of paracetamol per kilogram of body weight. G3: 400 milligrams of C. sinensis L. and 250 milligrams of paracetamol per kilogram of body weight. G4: injection of 0.3 milligrams of zinc nanoparticles and 250 milligrams of paracetamol per kilogram of body weight. G5: injection of 0.5 milligrams of zinc nanoparticles and 250 milligrams of paracetamol per kilogram of body weight. G6: injection of 0.3 milligrams of silver nanoparticles and 250 milligrams of paracetamol per kilogram of body G7: injection of 0.5 milligrams of silver nanoparticles and 250 milligrams of paracetamol per kilogram of body, G8: 250 milligrams of paracetamol per kilogram of body administered intravenously, the blood bled for 30 days after receiving all dosages orally once daily for 21 days. When rats were given injections of 0.5 mg of nanoparticles and when injections of 250 mg of a black tee., it was discovered that the concentration of Malondialdehyde MDA, Lipid Peroxidation LPO, Triacylglycerid, cholesterol levels, and glucose decreased significantly. In contrast, Glutathione peroxidase GPX and protein levels are increased considerably. This was due to the injections’ preventive and antioxidant action against the oxidative stress brought on by the paracetamol height dose.

The Effects of the Processing of Positive Memories Technique on Posttrauma Affect and Cognitions Among Survivors of Trauma: Protocol for a Daily Diary Study
Authors: Greene Talya , Contractor Ateka A , Dicker-Oren Sheila Daniela , Fentem Andrea , Sznitman Sharon R
Published: January 2024

Background

The Processing of Positive Memories Technique (PPMT) is a promising new treatment approach for posttraumatic stress disorder (PTSD), which involves detailed narration and processing of specific positive autobiographical memories. Indeed, preliminary case-series studies have found reductions in PTSD symptoms, negative affect, and negative cognitions among survivors of trauma who have received PPMT. However, PPMT’s effects have not been investigated at the daily level. In this study, we describe the protocol for a study that will examine the daily-level impacts of PPMT in a trauma-exposed, nonclinical community sample.

Objective

This study uses an innovative research protocol that combines case-series design and daily diary approaches to examine changes in daily affect, daily cognitions, and daily PTSD symptoms pre- and post-PPMT. We hypothesize that at the daily level, in comparison to their own pre-PPMT levels, following the PPMT intervention, participants will report (1) a lower count of endorsed daily PTSD symptoms, (2) increases in daily positive affect and decreases in daily negative affect, (3) increases in positive affect reactivity to daily positive events, and (4) decreases in daily posttrauma cognitions.

Methods

We are currently recruiting participants (target n=70) from a metroplex in the southwest United States. Following a screening survey, eligible participants complete a preintervention baseline survey, followed by 21 daily surveys in their natural environments. Then, they receive 4 PPMT sessions on a weekly basis. After the conclusion of the PPMT intervention, participants complete a postintervention outcome survey and 21 daily surveys. To compare daily affect, daily cognitions, and daily PTSD symptoms before and after PPMT, we will use the daily diary report data and conduct multilevel random intercepts and slopes linear regression models.

Results

Data collection was initiated in March 2022 and is expected to end by June 2024. As of November 28, 2023, a total of 515 participants had consented to the study in the screening phase. No analyses will be conducted until data collection has been completed.

Conclusions

Study findings could clarify whether deficits in positive autobiographical memory processes may also characterize PTSD alongside deficits in traumatic memory processes. Furthermore, PPMT could be an additional therapeutic tool for clinicians to help clients reduce posttraumatic distress in their everyday lives.

Indonesian Political Populism in the Agrarian Sector
Authors: Faiz Kasyfilham
Published: January 2024

This article seeks to understand the role of populist ideology in marginalizing the agrarian sector and the agrarian populism movement in Indonesia in the Reformation Era. Indonesia is an agricultural country, so such marginalization and the limited involvement of the agrarian movement is ironic. Development studies see the marginalization of the agrarian sector as a consequence of the reorientation of economic development towards the industrial and service sectors, mostly in urban areas. Studies like this often do not look at the political side of the marginalization. This study aims to fill this gap by analyzing the phenomenon in Indonesia utilizing Margaret Canovan’s populist approach. The findings show the influence of political populism on the marginalization of the agrarian sector in the reformation era in Indonesia. Pragmatic, populist leaders exploited ‘the people’ as a political rhetorical tool to gain power without touching the agricultural sector where ‘the people’ reside.

Effect of Fluraton and male cultivar on embryonic development of flowers of date palm (Phoenix dactylifera L.) C.V.‘Barhee
Authors: F. Al-Mahmoudi Sorour J. , H. Alnajjar Mohammed A. , F. Alpresem Wasen F.
Published: January 2024

This study explores the influence of Fluoraton treatment and male cultivar selection on the embryonic development of offshoot flowers in tissue-cultured date palms (Phoenix dactylifera L.), specifically focusing on the 'Barhee' cultivar. Female offshoots, derived from tissue culture, were subjected to inoculation with two male cultivars, namely Al-Ghanamy Al-Akhdar and a male-seed strain. Concurrently, Fluoraton treatment, administered at concentrations of 0, 0.3, and 0.6 g L-1, was applied to the female inflorescences. Microscopic examinations unveiled significant impacts on pollen tube development, fertilization, and embryonic sac growth. These findings offer valuable insights into optimizing the pollination process, ultimately leading to enhanced fruit production. The study underscores the significance of employing Fluoraton treatment and selectively choosing certain male cultivars over others for the pollination of female cultivars, given their pivotal role in expediting the early ripening of fruits. Notably, the male was utilized in the pollination process independently of the female variety, as no discernible differences were observed between the flowers of the two female cultivars. Keywords: Fluraton, male cultivar, embryonic development, flowers, date palm, Barhi.

Published: January 2024

The article examines the foreign policy strategies of the third President of the Republic of Cyprus, Georgios Vasiliou (1988-1993), through the prism of the anthropology of international relations. The main emphasis is on his attempts to resolve the Cyprus conflict and successfully integrate Cyprus into the EU. The analysis explores the interconnection of various factors in Cyprus’s foreign and domestic policies, which are related to the peculiarities of its political culture and internal party-political processes. The authors conclude that Vasiliou’s policy was largely shaped by the peculiarities of his personality, biography, education level, and overall political culture. The correctness of Cyprus’s European choice and Vasiliou’s leading role in this process is yet to be evaluated by future generations. It is this choice that allowed Cyprus to timely initiate the mechanisms of modernization, transforming it into a modern democratic and innovative state. The work incorporates littleknown biographical facts and materials from the Cyprian newspaper and personal interviews with the former president.

Today many young members of the Sindhi community are migrating from villages to cities in Pakistan, where the national language, Urdu and the co-official language, English, dominates. This study investigates the daily language patterns of transplanted Sindhi speakers and the impact of such patterns on their mother tongue. Furthermore, as these speakers frequently switch from one language to another due to exposure to multilingualism in urban settings, this study determines the dominant language being used by young Sindhis in their mixed discourse, compared to the discourse of older Sindhis. Reasons for adopting other languages in academic institutions and home-settings were also investigated. A qualitative case study was conducted to obtain detailed responses about the linguistic choices of twenty young Sindhi speakers. Two Sindhi families were also observed to study the language choices across generations in home-settings, and semi-structured interviews were conducted to determine reasons for the mixed languages which emerged. The data were analysed using frequency analysis for linguistic choices and thematic analysis of the daily life discourse. Results show that the young Sindhis in the city of Karachi are using dominant languages Urdu and English in their daily life and have higher proficiency in Urdu and English as compared to their mother tongue Sindhi. Moreover, there are several social, economic, and cultural reasons for switching from one language to another among the younger Sindhi generation, in contrast to the older Sindhi generation.

Text complexity impact on immediate recalls and range of metadiscourse markers remains a research niche due to the lack of multidisciplinary data necessary to shed light on the issue. The current study aims to identify effects of text complexity and Russian-English discourse differences on immediate text-based recalls relating to the amount and type of the information reproduced. For the research purposes we engaged 94 native Russian speakers as respondents in a text-retelling task to explore the amount of propositions recalled from an opinion article and the range of discourse markers employed. The reading text and text-based recalls were contrasted on informative and linguistic levels. The informative complexity of the reading text was evaluated on the basis of propositional analysis, and the linguistic complexity was carried out on the basis of descriptive parameters (word and sentence length, proportion of long words), readability index, word complexity and range of metadiscourse markers. The study revealed that the complexity level of the reading text is a strong predictor of propositional recall. The comparative analysis indicated a slight decrease in metrics of descriptive parameters. We also revealed that high ability readers make a choice in favor of superordinate propositions recalling about 60% of them and losing over 70% of the subordinate propositions. They also tend to shift the metadiscourse patterns of the original text from interactive to more logical ones by loosing hedges, emphatics and evidentials. The study furthers our understanding of cross-linguistic differences in the use of metadiscourse, its results will find application in discourse complexology and natural language processing.
Metaphoric gestures in simultaneous interpreting
Authors: Leonteva Anna V. , Cienki Alan , Agafonova Olga V.
Published: January 2024

The paper deals with the degree to which interpreters incorporate visible behaviors from the people they are interpreting into their own practice. Since metaphoric gestures objectify abstract concepts in visible form, it is worth exploring the degree to which interpreters replicate such gestures of those whose speech they are interpreting; this can indicate how much they are employing the original speakers’ mental imagery connected with those abstract concepts. This imagery for the source domain of the metaphor ranges from highly iconic (high metaphoric) to low in iconicity (low metaphoric). The hypothesis is that interpreters use low metaphoric gestures rather than high metaphoric ones, due to the discourse type (interpreted speech). We performed formal visual and semantic analyses of ten-minute videos of interpreting a scientific lecture for the general public on a psychological topic from English into Russian. First, we analyzed the functions of the gestures in the source videos to identify metaphorically used gestures (e.g., depicting abstract ideas); then we studied the functions of the interpreters’ gestures. The results indicate a predominance of low-level, schematic metaphoricity in the interpreters’ gestures (e.g., simple ontological metaphors, as if presenting ideas on the open hand). Such results might be explained by the time pressure which leads to a decrease in mental imagery of the interpreters. We see a difference between the known role of gestures when speakers are formulating their own ideas (in thinking for speaking) and their role in simultaneous interpreting (when speakers are rendering others’ ideas, rather than forming their own ones).
Studi terhadap Polemik antara Larangan dan Pembolehan Penulisan Hadis
Authors: Wahyudi Rizki Imam
Published: January 2024

Hadith, which is the second source of Islamic law, apart from functioning to explain the Qur'an, also serves to reinforce the laws of the Koran and serves to establish laws that are not found in the Koran. There are two contradictory hadiths related to the writing of hadith: the hadith which prohibits and the hadith which encourages the writing of hadith. The orders to pray, pay zakat, and perform Hajj are only mentioned in general. The Qur'an does not explain the number of cycles and the ways of performing the prayers, does not specify the nisabs of zakat, and also does not explain the ways of performing the pilgrimage. But all of that has been explained in detail and interpreted as broadly as possible by hadith. This research is a study that uses the literature review method which aims to discuss the polemic between the prohibition and permissibility of the use of hadith. Seeing the importance of the position of the hadith, this paper wants to discuss the condition of the hadith at the time of the Prophet and his companions, which is the most important phase of the history of hadith. This discussion includes the understanding of hadith and sunnah, how friends receive hadith from the Prophet, discussions about the prohibitions and recommendations for writing hadith, and the attitude of friends towards the transmission of hadith. The books used are the opinions of previous scholars and authors, and the journals used are sourced from updated journals.
Ikhtilaf Al-Hadits: Penyebab dan Pendekatan Penyelesaiannya
Authors: Ismail Nurjannah , Rahmah Yus Dhiya
Published: January 2024

Hadiths play a pivotal role in shaping norms and laws for the Muslim community in Islam, but they often give rise to controversies and differences in interpretation and application. This article aims to explore the phenomenon of Ikhtilaf Al-Hadith, which refers to the divergence in the understanding of Hadiths among Islamic scholars and its methods of resolution. Employing a literature analysis method, the author references pertinent sources for this study. The findings reveal that Ikhtilaf Al-Hadith can emerge due to various factors, including the content of the Hadith, the context of its delivery, methodology, and ideology. Resolution approaches include compromise, tarjih (selecting the stronger Hadith), or nasakh (abrogation of one Hadith in favor of another). Hence, a meticulous understanding and methodological approach are essential to maintain consistency in comprehending and applying Hadiths in Islam. Compromise, tarjih, and nasakh serve as methods for resolving discrepancies between Hadiths, and contextual and historical understanding is crucial in interpreting apparently contradictory Hadiths.

ABSTRAK

Hadits dalam Islam memiliki peran sentral dalam membentuk norma dan hukum bagi umat Islam, tetapi seringkali menimbulkan kontroversi dan perbedaan dalam pemahaman serta penerapannya. Artikel ini bertujuan untuk mengeksplorasi fenomena Ikhtilaf Al-Hadits, yang merujuk pada perbedaan pemahaman hadits di kalangan ulama Islam, serta metode penyelesaiannya. Dalam penelitian ini, penulis menggunakan metode analisis literatur dengan merujuk pada sumber-sumber yang relevan. Hasil kajian menunjukkan bahwa Ikhtilaf Al-Hadits dapat timbul akibat berbagai faktor, termasuk konten hadits, konteks penyampaian, metodologi, dan ideologi. Penyelesaiannya dapat dilakukan melalui kompromi, tarjih (menentukan hadits yang lebih kuat), atau nasakh (membatalkan salah satu hadits dan menerima yang lainnya). Oleh karena itu, pemahaman yang teliti dan pendekatan metodologis diperlukan untuk menjaga konsistensi dalam memahami dan menerapkan hadits dalam Islam. Kompromi, tarjih, dan nasakh adalah metode yang digunakan untuk menyelesaikan perbedaan antar hadits, dan pemahaman kontekstual serta historis juga penting dalam menafsirkan hadits yang mungkin tampak bertentangan.
