The Reflection of The Juristic Identities of Tahavî And Cessâs In The Comments of Ahkam In The Context of Hajj Worship
Full text linkAhkâmü’l-Kur’ân türü eserler ibâdât, muâmelât ve ukûbât/ceza hukuku ile ilgili (ahkâm) ayetlerinin tefsirine dair yazılan eserlerdir. Çalışmada makalenin hacmi de dikkate alınarak Hanefi doktrini bağlamında Tahâvî ve Cessâs’ın Ahkâmü’l-Kur’ân tefsirleri ile başta aynı müellifler olmak üzere diğer bazı Hanefi füru-i fıkıh eserlerinde hac ibadetinin ele alınış biçimleri incelenmektedir. Çalışmanın amacı; fıkıhçı kimliği ile tanınan müelliflerin tefsir eserlerinde “hac ibadeti” bağlamında fıkhi konulara ne ölçüde yer verdiği, ilgili konunun fıkıh ile tefsir (Ahkâmü’l-Kur’ân) eserlerinde işlenen benzer ve farklı yönleri ve füru-i fıkıh eserlerinin muhtevalarının gelişim seyrini tespit etmektir. Bu bağlamda Ahkâmü’l-Kur’ân ile füru-i fıkıh eserlerinde ele alınan meselelerin farklı bakış açıları ile değerlendirilmesinde müelliflerin ilmi yetkinliklerinin etkili olduğu görülmektedir. Füru-i fıkıh literatürünün muhtevasının gelişmesinde ise müelliflerin ilmi birikimlerinin yanı sıra yaşadıkları dönemde ortaya çıkan yeni sorunlar ve sorulan yeni fıkhi soruların etkili olduğu söylenebilir. Nitekim ele alınan ahkâm tefsirleri ile fıkıh eserleri süreç içerisinde olgunlaşmış, bir dönemde ilgili literatürde ele alınan bazı konular süreç içerisinde ihtiyaca göre ya geliştirilmiş veya kapsam dışında tutulabilmiştir. Son olarak çalışma ile Tahâvî ve Cessâs’ın ahkâm tefsirlerinde akli ve nakli delillerle fıkhi analizlerde bulundukları ve hac ibadeti ile ilgili bazı konuların ahkâm tefsirlerine nazaran fıkıh eserlerinde daha yüzeysel işlendiği tespit edilmiştir.Ahkâmü'l-Kur'an type works are written on the interpretation of the verses (ahkam) related to worship, transactions and ukûbât/criminal law. In the study, taking into account the volume of the article, the ways in which the pilgrimage is discussed in the Ahkâmü'l-Qur'an commentary of Tahâvî and Cessâs and in some other Hanafi füru-i fiqh works, especially by the same authors, are examined in the context of Hanafi doctrine. The purpose of the study; The aim is to determine the extent to which authors known as fiqh scholars include fiqh subjects in the context of "pilgrimage" in their exegetical works, the similar and different aspects of the relevant subject covered in fiqh and exegesis (Ahkam al-Qur'an) works, and the course of development of the contents of the fiqh works. . In this context, it is seen that the scientific competencies of the authors are effective in evaluating the issues discussed in Ahkam al-Qur'an and Füru-i Fiqh works from different perspectives. It can be said that the development of the content of the Füru-i Fiqh literature was influenced by the scientific knowledge of the authors as well as the new problems that arose in the period in which they lived and the new fiqh questions asked. As a matter of fact, the discussed tafsirs of judgments and works of fiqh have matured in the process, and some subjects covered in the relevant literature in a period have either been developed or excluded from the scope according to the need in the process. Finally, it has been determined in the study that Tahavi and Cessâs made fiqh analyzes with rational and transmitted evidence in their commentaries on the rules, and that some issues related to the pilgrimage were treated more superficially in their works on fiqh compared to the commentaries on the rules
Investigation of microstructure, hardness, corrosion and machinability properties of commercially pure aluminum alloyed with rare-earth elements
Full text linkIn this study, three different rare-earth elements, namely gadolinium (Gd), yttrium (Y) and neodymium (Nd), were added to commercially produced Al99.8 aluminum at various weight ratios (0.1%, 0.2% and 0.3%). Since rare-earth elements were added as a magnesium-based master alloy, commercial Al99.8 alloy containing 0.7 wt% Mg was also cast in the experimental study to investigate the effect of magnesium added to the alloy. The effects of rare-earth elements added to commercially pure Al99.8 aluminum on the microstructure, hardness and electrochemical corrosion behavior in 3.5% NaCl environment in the casting position of the alloys were investigated. In addition, the samples of the alloys were drilled with a spindle speed of 4000 rpm and a feed rate of 200 mm/min and the effects of rare-earth elements on thrust force, burr and surface morphology were investigated. It was observed that intermetallic compounds containing these elements were formed in the microstructures of the casting alloys to which rare-earth elements were added, the microstructure generally became thinner depending on the added ratios, the grain structure changed from columnar to equiaxed and microsegregation was eliminated compared to the alloy containing Mg. In electrochemical corrosion tests, the worst corrosion resistance was found in the alloy containing Mg, while the Icor values indicating the corrosion rate were found to increase with the addition of Gd, Y and Nd, respectively, compared to the Al99.8 sample. Scanning electron microscope examinations of corroded surfaces showed that the alloys started to dissolve from the intermetallic compound and matrix interface. While the corrosion mechanism was seen to be pitting corrosion in the alloy containing Mg, the mechanism was found to be microgalvanic corrosion in the alloys containing rare-earth elements. When the samples containing rare-earth elements were drilled, less thrust force was generated compared to Al99.8 aluminum. The highest amount of burr was generated in the Al99.8 sample. In addition, better surface quality was obtained when the samples were drilled by adding rare-earth elements

The data were collected with the CMS detector and correspond to an integrated luminosity of (Formula presented). The observations are found to be in agreement with the expectation from standard model processes. Limits at 95% confidence level are set on the product of the (Formula presented) production cross section and its branching fraction to tau lepton pairs for a range of (Formula presented) boson masses. For a narrow resonance in the sequential standard model scenario, a (Formula presented) boson with a mass below 3.5 TeV is excluded. This is the most stringent limit to date from this type of search. © 2025 CERN, for the CMS Collaboration
The performance of Ag2S/X (X: Co and Ni) nanocrystals as counter electrodes in dye-sensitized solar cells
Full text linkIn the present study, Silver sulfide (Ag2S)-based nanocrystals (NCs) were synthesized by employing a facile hot injection method. These NCs are utilized as counter electrodes on dye-sensitized solar cells (DSSCs), representing a smart approach that utilizes these NCs as catalysts instead of platinum (Pt) for the first time. The study provides a comparative analysis of the performance of Ag2S-based counter electrodes (CEs) in DSSCs technologies the traditionally compared Pt-based electrodes under identical conditions. The findings showed that the Ag2S-based DSSCs exhibited a power conversion efficiency (ƞ) that was approximately 5.2 % higher than that of the platinum-based DSSCs. Consequently, the results of this study demonstrate that Ag2S-based NCs possess the potential to function as novel counter electrode materials for low-cost, Pt-free solar cells. Moreover, the results of this study bear considerable implications for the development of cost-effective and sustainable solar energy solutions. The advent of Ag2S-based NCs signifies a significant milestone in the quest for sustainable and efficient energy solutions. This study also invites further exploration into other potential material combinations and synthesis methods that could enhance the properties and performance of DSSCs
Analysis of anthropometric measurements in u-15 female weightlifters using kinect camera and comparison with traditional methods
Full text linkAnthropometric measurements are important in a wide range of areas, from athlete selection to performance analysis and medical exercise applications. With its portable and cost-effective structure, Microsoft Kinect offers significant advantages in measuring human movements and provides valuable data in the fields of sports science and medicine. The aim of this study is to compare certain anthropometric measurements of adolescent female weightlifters in the U-15 age category with Kinect V2 and traditional methods. Twelve athletes who won medals in international weightlifting championships were included in the study. Anthropometric evaluations of each athlete were performed using Kinect V2 and the traditional method. Differences between measurements were analyzed with Bland–Altman plots and Pearson correlation coefficients. Kinect was found to exhibit less variability and higher coherency in measurements of humerus, forearm, trochanter-tibiale laterale, tibial lengths, and shoulder width. It has been observed that the traditional method provides more coherence results in hand length measurements. Kinect was found to exhibit less variability and higher coherency in measurements of forearm, trochanter-tibiale laterale, tibial lengths, and shoulder width, indicating its potential as a reliable tool for these parameters. Notably, Kinect demonstrated high reliability for tibial length (ICC 0.918) and moderate reliability for trochanter-tibiale laterale (ICC 0.737), showing its effectiveness in these measurements. Additionally, Kinect exhibited lower variation and higher coherency in most measurements compared to manual methods, supporting its consistency and repeatability in anthropometric assessments. These results indicate that Kinect may be a suitable tool for some measurements but that traditional methods may be preferable for hand length measurements. These findings suggest that Kinect can be used effectively for certain anthropometric measurements in sports and medical science
Gelişmekte olan ülkelerde ekonomik büyüme ve finansal gelişme: canning ve pedroni'nin panel nedensellik analizi ile ampirik bir araştırma
No full textThis study aims to investigate the causal relationship between financial development (FD) and economic growth (EG) from 1990 to 2022. 45 developing countries and the approach recommended by Canning and Pedroni (2008) has been applied to determine this link. Based on the result of Unit Roots tests, the variables are first-order integrated. The cointegration connection indicates that, despite ongoing external shocks, the time series are linked in a long-term equilibrium. For the whole panel, the causality results show a long-run, unidirectional causal relationship. The long-run causal link from EG to FD is not supported by panel causality data. Examining group averages, there is no long-term causal relationship from FD to EG or EG to FD. The results demonstrate the validity of the supply-leading viewpoint and demonstrate that financial market reforms, financial market liberalization policies, and improved financial intermediation services all have a favorable impact on EG in the economies under discussion.Bu çalışma, 1990-2022 dönemi için finansal gelişme (FD) ile ekonomik büyüme (EG) arasındaki uzun vadeli nedensel bağlantıyı incelemektedir. Bu çalışmada 45 gelişmekte olan ülke için finansal gelişme (FD) ile ekonomik büyüme (EG) arasındaki ilişki Canning ve Pedroni (2008) panel nedensellik testi ile incelenmiştir. Birim Kök testleri sonucuna göre değişkenler birinci dereceden eşbütünleşiktir. Eşbütünleşme bağlantısı, devam eden dış şoklara rağmen zaman serilerinin uzun vadeli bir dengede bağlantılı olduğunu göstermektedir. Panelin tamamı için nedensellik sonuçları uzun vadeli, tek yönlü bir nedensellik göstermektedir. EG'den FD'ye uzun vadeli nedensellik bağlantısı panel nedensellik verileri tarafından desteklenmemektedir. Grup ortalamalarına bakıldığında FD'den EG'ye veya EG'den FD'ye uzun dönemli bir nedensellik ilişkisi bulunmamaktadır. Sonuçlar, arz odaklı bakış açısının geçerliliğini ortaya koymakta ve finansal piyasa reformlarının, finansal piyasa liberalizasyon politikalarının ve iyileştirilmiş finansal aracılık hizmetlerinin tamamının, tartışılan ekonomilerde EG üzerinde olumlu bir etkiye sahip olduğunu göstermektedir
Improving machinability of Ni-based Monel 400 superalloy: a novel thermal-assisted drilling method based induction heating
Full text linkNickel-based superalloys are classified as hard-to-cut materials due to their low thermal conductivity, high strain hardening, and hot hardness. Consequently, the machinability of these materials, which are utilised in a variety of high-tech industries, remains the subject of ongoing investigation. Different methodologies have been proposed for this purpose; however, thermally assisted machining is considered to be one of the most significant methods employed to enhance the machinability of difficult-to-cut materials. This approach is based on the principle of reducing material strength and providing an easier cutting process. In the present study, the thermal-assisted drilling machinability of Monel 400 Ni alloy was investigated using an induction heating method, and the effects of this process on the workpiece were analysed comprehensively. The findings demonstrated that thermal-assisted drilling at moderate temperature (300 °C) ensures a considerable enhancement in machinability, providing a 19% reduction in force and 31% reduction in torque on average and a decrease in burr formation and tool wear, without inducing substantial alterations in the material’s internal structure. However, whilst the process at elevated temperatures (600 °C) enhances machinability by reducing thrust force and torque by approximately 51%, substantial alterations in the material microstructure and a reduction in hardness and yield strength of approximately 9% are observed post-processing

Investigation of the mediating role of life satisfaction in the effect 5 od 6 of emotional labor on work-life balance
Full text linkPurpose: The aim of the research is to test the mediating effect of life satisfaction (LS) on the impact of emotional labor (EL) on work-life balance (WLB). Methodology: The research tested the mediating effect of LS on the impact of EL efforts of taxi drivers on WLB. The quantitative research used a questionnaire-based methodology to collect research data. Results: A positive and weak relationship has been determined between EL and LS. Additionally, the results also show a similar relationship between LS and WLB. However, no statistically significant relationship was found between EL and WLB. In addition, the impact of EL on LS and the impact of LS on WLB have also been determined. In a model without LS, it was observed that EL did not have a significant effect on WLB. Conclusion: Research findings are limited only to the perceptions of taxi drivers in a city. To generalize the results, the research model could be repeated in different cities and sectors for comparative analysis. Measures can be taken to improve employees' life satisfaction. Thus, the EL efforts of employees will not be in vain, supporting them in maintaining and improving their WLB
Involvement of mirnas in the cluster of metabolic factors of mets: Nutrition-genome-mets axis
Full text linkMicroRNAs (miRNAs) are key regulators of gene expression and play essential roles in physiological processes such as cell proliferation, apoptosis, and metabolism. They have emerged as promising biomarkers for the early diagnosis, prognosis, and treatment of Metabolic Syndrome (MetS). In recent years, exosome-derived miRNAs, known as “xeno-miRNAs”, which are derived from food, as well as circulating miRNAs, have emerged as areas of intense research due to their potential effects on metabolic disorders. miRNAs influence fasting blood glucose and insulin resistance through mechanisms such as β-cell differentiation, insulin gene transcription, and PI3K–AKT pathway activation. Additionally, miRNAs play important roles in regulating MetS components, as follows: obesity through adipogenesis and lipogenesis; hypertension through regulation of the renin–angiotensin system and vascular tone; and dyslipidemia by modulating lipid metabolism. Emerging evidence suggests that nutrients such as polyphenols and specific dietary patterns can alter miRNA expression, potentially impacting metabolic health. Understanding the interactions between diet and miRNA regulation offers novel insights into the prevention and treatment of MetS. This review explores the mechanisms by which miRNAs influence MetS components, and highlights the growing potential of nutrient-regulated miRNAs as therapeutic targets within the framework of precision nutrition and personalized metabolic disease management
