المراجعات المبكرة للجامع الصحيح للبخاري: الترمذي ومصطلحه "حسن صحيح" أنموذجا
Authors: Sarmını Mohamad Anas
Published: December 2024

تدَّعي الدراسة بأن منزلة صحيح البخاري جاءت تدريجيا بعد طول مراجعة لعدالة رواته وصحة مروياته، وتدعي بأن الترمذي في جامعه قد مثَّل إحدى المراجعات المبكرة لأحكام شيخه البخاري، وذلك باعتباره أخرج الكثير من أحاديث الصحيح في جامعه ثم حكم عليها بغير الصحة. اختارت الدراسة ميدانا لها الأحاديث التي حكم عليها الترمذي بحسن صحيح وكانت مما أخرجه البخاري، فبحثت أولا في دلالات هذا المصطلح وذهبتْ إلى أنه يدلُّ على رتبة تقع في أدنى مراتب الصحيح وهو دون الصحيح المطلق، وبيَّنت أن مردَّ ذلك هو إلى اختلاف مؤثر طرأ في إسناد الحديث أو متنه. اتخذت الدراسة من هذا الاصطلاح مدخلا لفهم أسباب نزول الترمذي بتلك الأحاديث عن رتبة الصحة، ومن ثمَّ قارنت بين إسناد الترمذي وإسناد البخاري للتأكد من كون العلة المذكورة قائمة فيهما وليست مختصة بإسناد الترمذي. كما أنها اتخذت من أبواب الطهارة في جمع الترمذي ميدانا تطبيقيا لتتبع هذه الأحاديث. وأثبتت الدراسة أن الترمذي كان محدثا ناقدا مستقلا باختياراته، وأنَّه أخضع عددا من أحاديث الصحيح للمراجعة، وبيَّن فيها رأيه بكل صدق ودقة، ولم تُعن الدراسة بالموازنة اختيار البخاري والترمذي وإنما عُنيت بإثبات تلك المراجعة، وبأن منزلة البخاري قد ثبتت موضوعيا ومع طول الزمن والمدارسة.تدَّعي الدراسة بأن منزلة صحيح البخاري جاءت تدريجيا بعد طول مراجعة لعدالة رواته وصحة مروياته، وتدعي بأن الترمذي في جامعه قد مثَّل إحدى المراجعات المبكرة لأحكام شيخه البخاري، وذلك باعتباره أخرج الكثير من أحاديث الصحيح في جامعه ثم حكم عليها بغير الصحة. اختارت الدراسة ميدانا لها الأحاديث التي حكم عليها الترمذي بحسن صحيح وكانت مما أخرجه البخاري، فبحثت أولا في دلالات هذا المصطلح وذهبتْ إلى أنه يدلُّ على رتبة تقع في أدنى مراتب الصحيح وهو دون الصحيح المطلق، وبيَّنت أن مردَّ ذلك هو إلى اختلاف مؤثر طرأ في إسناد الحديث أو متنه. اتخذت الدراسة من هذا الاصطلاح مدخلا لفهم أسباب نزول الترمذي بتلك الأحاديث عن رتبة الصحة، ومن ثمَّ قارنت بين إسناد الترمذي وإسناد البخاري للتأكد من كون العلة المذكورة قائمة فيهما وليست مختصة بإسناد الترمذي. كما أنها اتخذت من أبواب الطهارة في جمع الترمذي ميدانا تطبيقيا لتتبع هذه الأحاديث. وأثبتت الدراسة أن الترمذي كان محدثا ناقدا مستقلا باختياراته، وأنَّه أخضع عددا من أحاديث الصحيح للمراجعة، وبيَّن فيها رأيه بكل صدق ودقة، ولم تُعن الدراسة بالموازنة اختيار البخاري والترمذي وإنما عُنيت بإثبات تلك المراجعة، وبأن منزلة البخاري قد ثبتت موضوعيا ومع طول الزمن والمدارسة.

Authors: Loghmani Alireza , Kamalpour Mohammad , Amrollahi-Sharifabadi Mohammad , Tapehbour Mohammad Bahrami
Published: December 2024

Background & Objectives: The present study investigates the therapeutic potential of betaine-conjugated gold nanoparticles (AuNPs) in treating inflammation induced by heatstroke. While heatstroke is characterized by elevated body temperature and severe inflammation, which can lead to organ dysfunction, conventional treatments, such as cooling and supportive care have not been successful in preventing long-term damage. AuNPs function as targeted carriers for the delivery of bioactive agents, such as betaine, to inflamed tissues. Using a murine model of heatstroke, we assessed the effects of AuNPs, betaine, and their combination on inflammation markers and cellular stress.
Materials & Methods: The experimental animals were divided into groups receiving different treatments, and various outcomes, including cytokine levels (TNF-α, IL-6, IL- 10), heat shock protein (HSP70) expression, and splenocyte proliferation, were measured.
Results: The findings revealed that the combination of AuNPs and betaine significantly decreased the levels of pro-inflammatory cytokines (TNF-α and IL-6) while increasing those of the anti-inflammatory cytokine IL-10. Furthermore, the therapy reduced HSP70 expression, indicating lowered cellular stress in the AuNP-betaine group. Moreover, treatment with AuNP-betaine significantly enhanced lymphocyte proliferation, suggesting improved immune function under heatstroke conditions.
Conclusion: Our findings highlight the promise of betaine-conjugated AuNPs as an innovative therapeutic approach in reducing inflammation and oxidative stress associated with heatstroke. The synergistic effects of nanotechnology and bioactive substances in modulating inflammatory pathways can be a promising strategy for managing heat-related inflammatory conditions.

Authors: N Mahdavi , M Shafiee-Motlagh , Z Cheraghi , H Jafari-Mansoorian , V Ramazani Doroh , L Tapak , M Afshari , A Doosti-Irani
Published: December 2024

Introduction: Workload and job satisfaction are among the most influential factors affecting job performance. Therefore, this study aims to assess the cognitive workload and job satisfaction and their impact on the quality of education faculty members provide.
Method: This study was conducted among 34 faculty members through a census. The NASA-TLX tool was used to assess cognitive workload, and a job satisfaction scale was employed to evaluate job satisfaction. Moreover, the training quality score was considered a criterion for assessing the educational performance of the participants. To determine the role of explanatory variables on the level of mental workload, multiple linear regression was used at a 95% confidence level.
Result: The mean cognitive workload of faculty members was 52.94 ± 24.48. Efficiency and time demand scored the highest and lowest among the subscales of workload, respectively. Job satisfaction was 56.85 ± 27.61, with satisfaction with the department head and colleagues ranking highest and satisfaction with salary being the lowest in job satisfaction. The cognitive workload had a non-significant relationship with job satisfaction (P = 0.08, r = 0.56). However, the relationship between teaching quality and both cognitive workload and job satisfaction was not statistically significant.
Conclusion: No significant relationship was observed between cognitive workload, job satisfaction, and teaching quality scores. However, it is recommended that measures be taken to improve the quality of work life for faculty members to enhance the quality of education they provide.

Authors: M Seif , M Amouamouha , A Sharifi
Published: December 2024

Introduction: Education in medical sciences is one of the most basic structures of societies, the most desirable outcome of which is improving the health level of individual members of society. Therefore, the current study was conducted to review the plan of integrating medical education with the service delivery system in Iran from an educational perspective.
Method: This was a scoping review study. Data were collected using keywords in Magiran, ISC, SID, Pubmed, Scopus, Web of Science and Google Scholar databases in the period from 2001 to 2024. Screening and selection of documents was done according to Prisma instructions.
Results: In the initial search, 180 articles were found, with 19 included in the study. The results showed that the growth of the workforce, socialization of education, progress in the field of medicine, and increase in research rank are the strong points of this project. However, more attention is paid to the issue of treatment than education, conflict of interests, and low quality of services in hospitals. Education and lack of research funds are among the existing matters.
Conclusion: The integration of medical education with healthcare services has successfully achieved its primary goals. Nevertheless, it seems that medical education in universities has been under the shadow of the debate on health provision and medical services, and education and research have benefited less from the positive effects of integration.

Duloxetine for Postoperative Pain in Orthopedic Surgeries: A Review Article
Authors: Nankali Alireza , Sabouri Maryam , Gholamshahi Hediye
Published: December 2024

Postoperative pain plays a key role in patients’ satisfaction. Since opioids may cause dependence and have a high abuse rate, non- opioid drugs such as duloxetine are being investigated for their effect in this matter. This review investigated the pharmacokinetics and the effects of duloxetine on postoperative pain after orthopedic surgeries. Duloxetine is a dual serotonin and norepinephrine reuptake inhibitor that causes a synergistic effect and can help manage postoperative pain. For this cause, it is prescribed as 60 mg per day. There have been studies in recent years proving its effectiveness both in total hip and knee arthroplasties and elective surgeries. The collective data show that duloxetine can be used for postoperative pain management, and with minimal side effects, it can lower opioid usage and dependence. However, considering duloxetine side effects including gastrointestinal (GI) disturbances (nausea, constipation), dry mouth, and loss of appetite, and the limitations of current literature, further studies need to be conducted.
Interlanguage Pragmatic Competence Test for EFL Learners’ Request Speech Act: A Systematic Review
Authors: Ariani Musli
Published: December 2024

This paper intends to provide a range of possibilities for testing learners’ interlanguage pragmatic competence of request speech acts. A request speech act has scarcely been understood in the context of the sequences of talk that involve the pre-request, the request, and the post-request stages. Request speech acts unfold over multiple turns in conversation and are co-constructed by the interlocutors engaged in the conversation. Previous studies have provided robust sources for assessing learners’ request abilities. Some assessment tools such as the discourse completion test, both oral (ODCT) and written discourse completion test (WDCT), and role play (RP) are among the most popular tools generally used to test learners’ comprehension and production of English requests. While these tools suggest a promising outlook of learners’ interlanguage pragmatic competence, their lack of authenticity remains questionable, except for role plays based on carefully planned scenarios of learners’ daily experiences and interests. Current development of interlanguage measures has taken advantage of technology such as the use of role-play computer-based tasks (RPCBT), role-play virtual reality tasks (RPVRT), and computer-animated production tasks (CAPT). Hence, it is likely that an interactive form of assessment device that can unfold every move and act of learners’ performance during interaction may become a better alternative to resolve the problems of testing learners’ interlanguage pragmatic competence covering knowledge, comprehension, and production of pragmalinguistic and sociopragmatic abilities. However, the use of ODCT or WDCT, despite the drawbacks, remains a reasonable choice for eliciting learners’ off-line knowledge of normative conventions of pragmatic language use.

Published: December 2024

This study aims to analyze how the Village Unit Cooperative (KUD) Mino Saroyo in Cilacap Regency, Central Java Province in developing strong institutions to provide solutions for poverty reduction in the Coastal Area of Cilacap Regency. This research uses qualitative research methods, this research challenge Scoot's institutional theory (2008) which reveals that there are three pillars in institutional capacity building, including coastal community institutions, namely the Regulative pillar, Normative pillar and Cultural-Cognitive pillar. The results showed that KUD Mino Saroyo is an independent cooperative with many business units with turnover reaching tens of billions. KUD Mino Saroyo is an example of a cooperative with innovation in managing business units to successfully obtain large profits and help reduce poverty in the coastal region of Cilacap. Suggestions of this study, required the management of business units by personal competent per the field of business units. The theoretical implication is that there needs to be an additional competency factor in Merilee S. Grindle's theory. In determining the leader, the Normative aspect in Scott's theory needs to be differentiated in a society that still tends to choose leaders based on image and not based on competence. The election of the highest leader remains by the voting community per the values and norms believed by the community, but for the lower leaders who need special competence, for example to lead a cooperative business unit. The values and norms are not submitted to the voting community, but are determined by a competent and authorized institution, which is then appointed and appointed by the highest leader.

The Ordering Distribution and Competing Motivation of Evidential and Logical Causal Clauses in English and Chinese
Authors: Fu Wanying
Published: December 2024

The ordering distribution of causal adverbial clauses in English and Chinese differs due to distinct factors, with English clauses tending to appear finally and Chinese clauses initially. This study aims to analyze the ordering distribution of logical and evidential causal clauses in English and Chinese using Diessel's competing motivation model, investigating the interplay of semantic forces, syntactic processing, and discourse pragmatics. A corpus-based analysis was conducted on 800 sentences from the British National Corpus and the Lancaster Corpus of Mandarin Chinese, focusing on four causal subordinators in each language. The results reveal a clear cross-linguistic distinction: In Chinese, evidential causal clauses occur initially at 82.5%, driven by iconicity and discourse coherence, while logical causal clauses show a lower initial occurrence rate of 67.3%. Conversely, English causal clauses tend to occur in final positions, with evidential clauses at 91.66% and logical clauses at 84.2%, due to the relative semantic independence, functioning as independent processing units. The ordering distribution reflects competing motivations: Chinese prioritizes iconicity and discourse coherence, while English emphasizes syntactic independence and processing ease. The study provides new insights into the interaction of semantic, syntactic, and pragmatic forces in shaping clause positioning across languages.

ZnAl2O4@ZnO an effective, heterogeneous catalyst for the synthesis of β-enaminones and β-enaminoesters
Authors: Anouar Harrad, Mohamed , Semane Adnan , Badereddine Mohammed , Tounsi Abdessamad
Published: December 2024

Using ZnAl2O4@ZnO as a catalyst, an environmentally friendly and very effective method has been developed to selectively add a ring to 1,3-dicarbonyl compounds and aromatic, aliphatic primary amines. A wide variety of bis(β-enaminones) and bis(β-enaminoesters) can be synthesized using this highly versatile method, which provides good yields. This procedure can be carried out at room temperature, which is environmentally advantageous as it utilizes ZnAl2O4@ZnO as a heterogeneous, recyclable and stable catalyst under free solvent conditions. A co-precipitation reaction at constant pH was used to prepare this catalyst, and spectral analysis (X-ray diffraction, FTIR) and morphological characterization techniques (SEM, EDX) confirmed its morphological structure.

The current study aims to maximize the recovery of antioxidant phenolics from Algerian Trifolium tomentosum L. using an innovative green process: ultrasonic assisted extraction (UAE). Firstly, four different solvents were used: 50% acetone, 50% ethanol, 50% methanol, and 100% ethyl acetate, as well as four different extraction methods: maceration, refluxed extraction, Soxhlet extraction, and UAE. The classification of the best solvent (50% ethanol) and most effective extraction method (UAE) on the basis of quantified total phenolic content (TPC) led to the second part, which focused on optimizing the UAE using response surface methodology (RSM) and a Box Behnken design (BBD). Algerian Trifolium tomentosum L. extract demonstrated intriguing total phenolic and flavonoid contents (TPC and TFC) greater than 30 mg GAE/g DW and 6 mg QE/g DW, respectively, and potential total antioxidant capacity (TAC), closer to 20 mg AAE/g DW, under the optimal conditions with 70% ethanol concentration, an extraction time of 30.45 minutes, and an extraction temperature of 75°C. Based on these findings, Algerian Trifolium tomentosum L. optimized extract can be used as a green natural ingredient in cosmetic formulations as well as a food preservative.
Chemical perspective on radionuclide emissions as atmospheric contaminants from nuclear reactors
Authors: Travin Sergey , Duca Gheorghe , Gromov Oleg
Published: December 2024

This study investigates the radionuclide emissions from nuclear power plants (NPPs), focusing on the gas-aerosol emissions from reactors such as VVER-440. The radionuclide composition of these emissions is analysed to determine the biological hazards they pose, particularly focusing on isotopes such as tritium and radiocarbon. The research highlights the patterns of radionuclide accumulation in fuel assemblies using "rank-size" coordinates, which provide a more visual and informative method compared to traditional atomic weight dependency analyses. The study introduces the Zipf-Mandelbrot type rank distributions and proposes that the emissions can be effectively monitored by measuring only a few key radionuclides, thereby simplifying the process. This method is validated across different reactor types, indicating its broad applicability. The research underscores the potential of using these patterns for more efficient regulation and control of radionuclide emissions from NPPs.

Published: December 2024

The efficiency of removal of glycerol, soaps, and unconverted acylglycerols by repeated washing with water, alcohol removal by distillation, distillation of esters, and using of sorbents, as well as a combination of these techniques, was evaluated. The use of a number of commercially available sorbents (Magnesol, talc, and coal) and ion exchange resins (KU-2-8, Purolite СТ275) was investigated. Glycerol and soap were found to be effectively removed with all tested materials except talc, while Magnesol and Purolite also effectively removed monoacylglycerols. However, none of the materials tested was able to withdraw diacylglycerols. A three-stage purification of esters was proposed. The latter includes the alcohol removal by distillation, which contributes to the additional settling of pollutants, vacuum distillation, and final use of sorbents (Purolite). The utilization of the indicated stages allows obtaining a product that meets the quality indicators of EN 14214. The proposed approaches will be valuable in the engineering of industrial technology for obtaining fuel-grade ethyl esters.

This study is primarily focused on evaluating the chemical composition of natural water in the locality of Cișmea, situated in the Orhei district, at the coordinates 47°24’56.0"N 28°45’05.9"E. The study includes an ad-hoc analysis of two types of water: surface water and underground water. General parameters were evaluated, such as pH, conductivity, hardness, chloride and sulphate content, as well as the content of certain chemical elements. The study results highlights significant deviations from the maximum admissible concentrations (MAC) for a series of indicators, such as As, Pb, Cd, Na, and B. The determined concentrations of these elements exceed the limits allowed by the legislation of Republic of Moldova and European Union: for As by 1.7–1.9 times; Cd by 3.4–3.5 times; Pb by 1.2–2.3 times; Na by 1.2–4.0 times and B by 1.6–3.3 times. Deviations of conductivity and sulphate parameters indicate the presence of a high level of dissolved solids in the groundwater of the locality’s wells and springs. The study also signalled the presence of significant concentrations of some heavy elements, such as Ba, Tl and Bi, which are not regulated by current legislation.

Published: December 2024

The aim of this study was to determine the physicochemical indicators and antioxidant activity from the unripe apples obtained after the agricultural thinning operation. Apples of the Coredana, Golden Rezistent, Reglindis and Rewena varieties harvested in 2020 were studied. Physicochemical indicators were analysed. The quantitative and qualitative determination of organic acids was carried out by the HPLC method, and of carbohydrates by capillary electrophoresis. Determination of antioxidant activity and total polyphenols content was evaluated by spectrophotometric methods. The highest amount of organic acids was obtained in the 45th days after full bloom (DAFB) of harvest, the predominant being malic acid with a value between 15.09±0.02 and 21.64±0.01 g/100g dry weight (DW). Sugars had the highest value in 97th DAFB, fructose being the main one (67.79±0.11 – 75.73±0.10 g/L). Total phenolic content and antioxidant activity showed maximum values at the beginning of fruit harvesting, having 916.67±0.17 – 1316.13±0.21 mg GAE/100g DW and ascorbic acid equivalent antioxidant capacity of 16.94±0.12 – 23.51±0.2 mg AAE/100g DW, respectively. It was concluded that thinned unripe apples represent a natural source of organic acids and carbohydrates, significant amounts of phenolic compounds with antioxidant properties. The study provides information on unripe apples that can be processed and optimally used for food purposes.

Authors: Agunov Aleksandr , Ivanov Denis
Published: December 2024

Purpose: to conduct an analysis aimed at identifying the shortcomings of the existing calculation methodology for catenary overhead catenaries of electrified railways under extreme temperature conditions. To demonstrate the need to implement modern calculation methods based on mathematical modeling using computer-aided design tools. Methods: development of a FEM model using the ANSYS Workbench software package, which allows determining the tension of the overhead catenary supporting cable taking into account heating from the flowing current under heavy-haul traffic conditions. Comparison of calculation results using the existing methodology and the developed FEM model. Results: the analysis showed that the current approach does not take into account important physical factors, which can lead to potential errors both in the design and operation of the overhead catenary. The results of the electrothermal-mechanical calculation using the developed FEM model reveal inconsistencies in determining the heating temperature and tension of the overhead catenary supporting cable, which indicates the need to revise the key parameters used in the existing calculation methodology. Practical significance: the difference in the calculation results shows the importance of implementing modern methods for determining the parameters required for design and operation and confirms the relevance of the study, especially in the conditions of organizing heavy-haul train traffic. The FEM models used in the study have a wide calculation functionality and the ability to specify various boundary conditions, such as ambient air temperature, current applied to the contact network wires, and wire tension. These models can be effectively used in design and scientific activities by specialists in various fields.
