Recitation Methodologies, Emrullah Tuncel (Istanbul: Marmara Universitesi Vakfi Yay., 2023)
Full text linkKur’an, Cebrail (a.s.) vasıtasıyla Hz. Peygamber’e (sav) tenzil olunan, tevatür ile nakledilen ve tilaveti ile ibadet olunan mûciz bir kelamdır. Usul kitaplarında aktarılan bu tanıma göre Kur’an’ı okumak ibadet olarak telakki edilmiş ve onu okuyanların sevap elde edeceği belirtilmiştir. Her hususta güzel bir örneklik teşkil eden Hz. Peygamber (sav) de, ümmetinin en faziletli amelinin Kur’an okumak olduğunu vurgulamış ve Kur’an’ın, kendisini okuyanlara kıyamet gününde şefaat edeceğini bildirmiştir. Zikredilen nebevî müjdeler, Müslümanları, ilâhî kelamı okumaya teşvik etmiş ve tarihin her döneminde Müslümanlar Kur’an ile hemhâl olma gayreti içerisinde olmuşlardır. Bu çaba ve gayret, Kur’an’a dair ilimlerin de ön plana çıkmasına vesile olmuş ve bu bağlamda Kur’an’ı usûlüne uygun ve doğru bir şekilde okumayı temin eden Tecvîd ilmine ayrı bir önem atfedilmiştir. Tecvîd ilmi ilk dönemlerde şifâhi olarak nakledilirken hicri 4. Asır ile birlikte ilk Tecvîd eserleri kaleme alınmaya başlanmıştır. Ağırlıklı olarak harflerin mahreç ve sıfatlarının izah edildiği söz konusu eserlerde temas edilen mevzulardan birisi de tilâvet çeşitleridir. Kıraat uleması, Kur’an ve sünnete muvâfık bir tilâvetin paradigmalarını serdetmişler ve bu suretle hatalı okuyuş usûllerinin önüne geçmeyi murad etmişlerdir. Doç. Dr. Emrullah Tuncel tarafından kaleme alınan Kıraat/Tilâvet Usûlleri isimli eser de, tecvîd eserlerinde zikredilen tilâvet tarzlarını altı ayrı başlık altında ele almış ve sahih bir tilâvetin çerçevesini çizmeye çalışmıştır. Bu bağlamda söz konusu tarzlar objektif bir tutum ile incelenmiş ve karar kısmında mutedil bir yaklaşım sergilenmiştir. Eserde, kişinin hocasından öğrenmiş olduğu Kur’an kıraatinin ne oranda makbul olduğu tartışmaya açılmış ve bununla beraber Kur’an tedrisatında müşâfehe metodunun tek başına yeterli olmayacağı ifade edilmiştir. Ayrıca şu ana kadar uygulanagelen kıraatin gözden geçirilerek sahih ve nitelikli bir Kur’an tilâvetine ulaşmak amaçlanmıştır.The Quran was sent to the Prophet through Gabriel (a.s.). It is a miraculous word that was revealed to the Prophet (pbuh), transmitted through tawatur, and worshiped by its recitation. According to this definition given in the Usul books, reading the Quran is considered as worship and it is stated that those who read it will receive rewards. Hz. who sets a good example in every respect. The Prophet (pbuh) also emphasized that the most virtuous deed of his ummah was to read the Quran and stated that the Quran would intercede for those who read it on the Day of Judgment. The mentioned prophetic good news encouraged Muslims to read the divine word, and in every period of history, Muslims have strived to become familiar with the Quran. This effort and diligence has led to the sciences related to the Quran coming to the fore, and in this context, a special importance has been attributed to the science of Tajwid, which ensures the proper and correct reading of the Quran. While the science of Tajwid was conveyed orally in the early periods, the first Tajwid works began to be written in the 4th century Hijri. One of the topics touched upon in these works, where the origin and adjectives of letters are mainly explained, is the types of recitation. Recitation scholars have presented the paradigms of recitation in accordance with the Quran and the Sunnah, and in this way, they have aimed to prevent erroneous recitation methods. Assoc. Dr. The work titled Recitation/Tilâvet Usûlleri, written by Emrullah Tuncel, discussed the recitation styles mentioned in tajwid works under six different headings and tried to draw the framework of an authentic recitation. In this context, the styles in question were examined with an objective attitude and a moderate approach was taken in the decision part. In the work, it is discussed how acceptable the Quranic recitation that a person has learned from his teacher is, and it is stated that the mushafehe method alone will not be sufficient in teaching the Qur'an. In addition, it is aimed to reach an authentic and qualified Qur'an recitation by reviewing the recitation practiced so far
Girth and groomed radius of jets recoiling against isolated photons in lead-lead and proton-proton collisions at √snn=5.02 tev
No full textThis Letter presents the first measurements of the groomed jet radius R-g and the jet girth g in events with an isolated photon recoiling against a jet in lead-lead (PbPb) and proton-proton (pp) collisions at the LHC at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The observables R-g and g provide a quantitative measure of how narrow or broad a jet is. The analysis uses PbPb and pp data samples with integrated luminosities of 1.7 nb(-1) and 301 pb(-1), respectively, collected with the CMS experiment in 2018 and 2017. Events are required to have a photon with transverse momentum p(T)(gamma) > 100 GeV and at least one jet back-to-back in azimuth with respect to the photon and with transverse momentum p(T)(jet) such that p(T)(jet)/p(T)(gamma) > 0.4. The measured R-g and g distributions are unfolded to the particle level, which facilitates the comparison between the PbPb and pp results and with theoretical predictions. It is found that jets with p(T)(jet)/p(T)(gamma) > 0.8, i.e., those that closely balance the photon p(T)(gamma), are narrower in PbPb than in pp collisions. Relaxing the selection to include jets with p(T)(jet)/p(T)(gamma) > 0.4 reduces the narrowing of the angular structure of jets in PbPb relative to the pp reference. This shows that selection bias effects associated with jet energy loss play an important role in the interpretation of jet substructure measurements
Struggling to exist between ethics and cronyism: the dilemma of unappointed doctoral graduate academics
No full textThe active involvement and inclusion of young scholars within established higher education systems are crucial for cultivating dynamism, fostering innovation, and ensuring the long-term sustainability of educational institutions. However, while some academic communities effectively harness the potential of young scholars, optimizing the benefits of their contributions, others fail to do so, leading to underutilized potential. This disparity warrants extensive research and examination. Cronyism, defined as the preferential treatment of certain groups through informal networks, undermines meritocracy and creates systemic inequalities in academic appointments and promotions. In T & uuml;rkiye, this issue is particularly significant due to the centralized structure of higher education and the influence of political and personal networks on academic decision-making.This research investigates the correlation between specific academic challenges such as limited access to resources, lack of mentorship, and inequitable opportunities, and the occurrence of cronyism, as well as explores the connection between cronyism and the career stagnation, job dissatisfaction, and psychological stress experienced by young academics. A qualitative research method was employed, and data were collected through interviews with 10 participants who were not appointed despite their success. The findings suggest that governmental interference in university administrations and policies threatens academic integrity and the protection of academic principles. Specifically, the study highlights that political appointments, biased funding allocation, restrictions on academic freedom, curricular interventions, and the manipulation of admission processes undermine academic integrity and principles. This study emphasizes the urgent need for transparent, merit-based appointment systems to address the detrimental effects of cronyism and foster a culture of academic ethics and fairness

No full textThis article addresses a key theory-practice gap in physical education teacher education (PETE) programs that can lead to the inadequate preparation of teachers for the realities they will face in schools. To improve the relevance of traditional PETE programs, the essential elements of implementing practice-based teacher education pedagogies are presented. The article provides readers with pedagogies that focus on the authentic practices in teacher education designed to train preservice teachers to learn from their teaching, as well as to understand the nuances of teaching in varied contexts
Rational design of ZnO/SrTiO3 S-scheme heterojunction for photo-enhanced piezocatalytic hydrogen production
No full textPhotopiezocatalysis have been frequently investigated for hydrogen evolution reactions in recent years. Herein, ZnO, SrTiO3 and ZnO/SrTiO3 S-scheme heterojunction were investigated for photo/piezocatalytic hydrogen production. Piezocatalytic hydrogen production under ultrasonic vibration by using ZnO, SrTiO3 and ZnO/SrTiO3 was obtained as 270 µmol g-1h?1, 200 µmol g-1h?1 and 1265 µmol g-1h?1, respectively. In addition, ZnO/SrTiO3 S-scheme heterojunction showed 2200 µmol g-1h?1 photopiezocatalytic hydrogen production under simultaneous exposure to white LED light and ultrasonic sound. ZnO/SrTiO3 heterojunction displayed significantly higher hydrogen production rate due to the decreased charge recombination, increased charge transfer with strong piezoelectric polarization and internal electrical field. The piezoelectric effect of ZnO/SrTiO3 heterojunction is also confirmed by piezoresponse force microscope technique with butterfly and phase hysteresis loops. Also, piezoelectric coefficient of ZnO/SrTiO3 found about 2-folds higher than those of their pristine forms. Electron transfer and reaction mechanism of ZnO/SrTiO3 and activity differences are confirmed by advanced optical and electrochemical techniques such as diffuse reflectance spectroscopy, electronic impedance spectroscopy, Mott-Schottky calculation and chronoamperometry. The whole electrochemical measurements have been performed with or without mechanical stress and light irradiation, which signify their band bending properties, electron transfer mechanism and catalytic activities. © 2024Selçuk Üniversitesi, S
A case-control study on sh2b1 gene variants in obesity and obstructive sleep apnea severity: genetic risk factors in the leptin signaling pathway
No full textBackground: Obstructive sleep apnea (OSA) is a common sleep disorder, frequently observed in obese individuals, with shared mechanisms involving leptin and its receptor, which regulate appetite and energy expenditure. SH2B1 is a key enhancer of signaling in the leptin receptor pathway. This study aimed to investigate the association between SH2B1 variants and OSA.
Research design and methods: This case-control study included 160 male patients with OSA and 76 healthy controls, stratified into subgroups based on BMI (≤25 kg/m2 and ≥ 30 kg/m2). Polysomnography and anthropometric measurements were performed, and genotyping of three SH2B1 variants (rs7498665, rs4788102, and rs7359397) was conducted.
Results: Mutant genotypes of all three SH2B1 variants were significantly associated with higher BMI. Additionally, normal genotypes of rs4788102 and rs7359397 were associated with higher apnea-hypopnea index (AHI) values, indicating a potential risk for OSA.
Conclusion: The findings suggest that while SH2B1 variants are strongly associated with BMI, specific normal genotypes may independently contribute to OSA risk by increasing AHI values
Specific and low-level detection of Hg2+ and CN- in aqueous solution by a new fluorescent probe: Its real sample applications including cell, soil, water, and food
No full textMercury (Hg) is one of the most hazardous heavy metals, posing a severe threat to human health. In response to this, we report a new fluorescence probe (HBT-PA) for Hg2+ detection that exhibits strong excited-state intramolecular proton transfer (ESIPT) and intramolecular charge transfer (ICT). HBT-PA exhibits an excellent "turnon" fluorescence response with high selectivity for Hg2+ ions and negative solvatochromism in many solvent environments. HBT-PA has excellent water solubility, rapid response (10 s), large Stokes shift (203 nm), and high selectivity and sensitivity for Hg2+ over other tested metal ions in water (with 0.01 % DMSO). The probe can detect Hg2+ within the micromolar range (0-50 mu M) and has a detection limit of 86 nM. In the presence of CN-, the fluorescence of a solution of [HTB-PA+ Hg2+] was quenched. Thus, the complex could be used to identify trace levels of CN- in water (with 0.01 % DMSO). The probe can be used to visualize Hg2+ ions in food, soil, and water. Moreover, it has been successfully used to develop smartphone applications, cotton swab, and polysulfone capsule kits for Hg2+ detection. Additionally, it has been effectively applied to the visualization of Hg2+ ions in living cells with low cytotoxicity and excellent biocompatibility
Hexadecimal permutation and 2D cumulative diffusion image encryption using hyperchaotic sinusoidal exponential memristive system
Full text linkThe performance of chaos-based image encryption (IE) highly depends upon chaotic system's complexity and diversity; and IE algorithm's permutation and diffusion strategies. Existing chaotic systems often face limitations in achieving sufficient complexity and dynamical richness, limiting their effectiveness in high unpredictability. To overcome these limitations, a novel hyperchaotic 2D sinusoidal exponential memristive system (2D-SEMS) is designed and validated through a hardware circuit. Additionally, a novel hexadecimal permutation and two dimensional (2D) cumulative diffusion IE (Hp2DCd-IE) is contrived using the 2D-SEMS. The 2D-SEMS is built upon two introduced designs of simplified exponential discrete memristors (SEDMs), forming the basis of its dynamic and chaotic framework. The 2D-SEMS validated by comparison with existing maps through an evaluation in terms of Lyapunov exponents (LE1, LE2), sample entropy (SE), correlation dimension (CD), and Kolmogorov entropy, and (KE), which are measured on average as 4.2889, 0.0250, 1.3204, 1.7599, and 1.6428. The Hp2DCd-IE is corroborated across wide range of cryptanalysis by comparing with the existing IE algorithms. The results demonstrate that the Hp2DCd-IE has high shuffling and manipulating performance thanks to complexity and diversity of the 2D-SEMS.

Zero Waste Applications For the Apple Processing Wastes: Recovery of Valuable Compounds by Supercritical CO2 and Wastewater Treatment by Advanced Oxidation
Full text linkThis study has focused on the characterization, recovery and treatment of apple processing wastes, which are important in terms of sustainability and circular economy. Apple processing wastewater (AW) was noted for its acidity (pH 4.2), high chemical oxygen demand (COD) (114 g/L), total solids (TS; 13.5 %) and oil/grease content (16.5 g/L), as well as the presence of valuable fatty acids and phenolics. Total phenolic content (TPC), total flavonoids content (TFC) and antioxidant activity were determined in the wastewater as 1660 mg GAE/L, 421 mg QE/L and 2.1 mM TE, respectively. The extraction of phenolic compounds from AW and apple pomace (AP) using supercritical carbon dioxide (SC–CO2) extraction was investigated as a first step. The results indicate that SC–CO2 extraction is effective in recovering phenolic compounds from apple processing wastes. The extraction yields for AW and AP using SC–CO2 reached up to 76 % and 43 % of the extractable oils, respectively. Recovery efficiencies of the TPC were observed to be up to 3.8 % for AW and 11.4 % for AP. Furthermore, the phenolic and fatty acid profiles of extracts were also evaluated, indicating the recovery of valuable compounds such as quercetin, catechin, procyanidin B2, ?–6 and ?–9 fatty acids. In terms of wastewater treatment, the use of ozone oxidation (OO) and supercritical water oxidation (SCWO) for the removal of COD, suspended solids (SS), TPC and toxicity from AW were also investigated. The OO exhibited relatively low COD removal efficiency, while SCWO demonstrated high efficiency ranging from 84 % to 99.8 %. This study has revealed that while SCWO effectively removes COD, TPC, SS and color from fruit processing wastewater, OO demonstrates greater effectiveness in reducing toxicity in the Vibrio fischeri test. © 2024 The Institution of Chemical EngineersMüberra Nur Kılıçarslan; Türkiye Bilimsel ve Teknolojik Araştırma Kurumu, TÜBİTAK, (120Y351); Türkiye Bilimsel ve Teknolojik Araştırma Kurumu, TÜBİTAK; KTUN, (222301003
The use of artificial intelligence and its ethical dimensions in public service provision
No full textThe development in the field of science and technology has continued uninterruptedly since the existence of humanity. However, the last few centuries have witnessed a much greater acceleration in this regard. Especially in recent times, the development of information technology has become very dizzying. We are witnessing a period in which, in addition to the many physical tasks and operations that humans can perform, issues such as decision-making and process management can be performed by machines instead of humans. With this new understanding of information technology called artificial intelligence, it has reached a point where machines can do much better than humans, much faster and almost error-free compared to humans. Machines that can think and make the right decisions according to the circumstances have become an important part of human life. Naturally, public administrations have started to benefit from these developments in large numbers and diversity. Many public services have started to be provided by machines or robots operating with artificial intelligence. However, this indispensable level of artificial intelligence machines in human life has brought along some important problems that cannot be kept out of sight. The issue of ethics, which is one of these important problems faced in the provision of public services, constitutes the field of investigation of this study. In this context, the main ethical problems arising in the provision of public services are discussed, and some suggestions are made. © 2025 Nova Science Publishers, Inc. All rights reserved
