Is It Time to Consider Science High School-Specific English? A Quantitative Case Study
No full textThe unique nature of each context has been recognized in applied linguistics to particularly address the specific needs of learners. This research aims to elucidate the specific requisites pertaining to English language skills within the cohort of high school science students. This quantitative study consists of 156 English as a foreign language students studying in high schools of science. The assembly of this study cohort was accomplished through the application of criterion sampling. Data pertinent to the study were gathered through a 28-item Likert-scale questionnaire. The analysis of the dataset was conducted employing descriptive statistical methods. Study results reveal that the majority of students at high schools of science desire to hone their speaking and reading skills to facilitate day-to-day interactions. However, a distinctive inclination surfaces in favour of scholarly and professional linguistic domains for the purpose of listening and writing. The findings underscore a compelling need for high school of science students to cultivate autonomy in their pursuit of EFL mastery, while engaging in collaborative endeavours with their peers. In light of the findings, the thoughtful restructuring of English language skill materials and activities is recommended. This restructuring should also be underpinned by a deliberate incorporation of the distinct requirements unique to high school science students. Pedagogical implications are discussed
Valorization of waste biomass derived activated carbon @expanded graphite for intensification of thermal characteristics of RT24 phase change material through shape-stabilization
No full textThe basic philosophy of this work is to create cleaner energy alternative materials for solar thermal energy storage applications. This experimental evaluation focuses on elevating the thermal characteristics of Rubitherm paraffin (RT24) by incorporating a hybrid matrix for shape stabilization. The hybrid matrix was fabricated by infusing expanded graphite (EG) (5 wt% and 10 wt%) into carbonized sugar beet pulp and vinasse wastes (BAC). The shape-stabilization of RT24 was carried out in vacuum to achieve uniform dissipation. The synthesized hybrid supporting matrices were adequately porous with highest BET surface area of 411.25 m2/g after adding EG(5 wt%) to BAC. According to TGA analysis BAC/RT24, BAC@5%EG/RT24(45 %) and BAC@10%EG/RT24 (60 %) were highly resistant to heat with corresponding mass loss of 39.4 %, 44.7 % and 59.8 % at around 280 degrees C. In accordance with XRD and FTIR analysis PCM composites have not displayed structural or chemical transformation due to the presence of EG or BAC. The melting and solidifying latent heat values of BAC@10% EG/RT24(60 %) were measured as 132.15 J/g and 129.42 J/g respectively. Also, BAC/RT24, BAC@5%EG/RT24 (45 %) and BAC@10%EG/RT24(60 %) have revealed high thermal reliability after performing 1000 thermal cycles with a variation of about 3 % in melting latent heat, thus signifying their adaptability into latent heat storage (LHS) systems. Thermal conductivity of the shape-stable BAC/RT24 composite was increased by 300 % compared to pure RT24 PCM as a result of adding 10 wt% EG to the composite. Especially BAC@10%EG/RT24 (60 %) composite can be utilized as cleaner energy alternative material for building solar thermal implementation because it had relatively higher LHS capacity and thermal conductivity value
Hardness and fatigue behavior of SiC, Al2O3, and blast furnace slag reinforced hybrid composites with Al6061 matrix
No full textThis study aims the use of blast furnace slag, produced as waste during the production of raw iron in blast furnaces, as a reinforcing element in the production of metal matrix composites. The Al6061 alloy, widely used in the automotive industry, was chosen as the matrix. SiC and Al2O3, two commercial ceramics frequently used in MMC production, were used as the second and third reinforcing elements in hybrid composite production, and their compatibility with blast furnace slag was investigated. Composites were produced using the stir-casting method with reinforcements sized between 22 and 59 mu m. Microstructure examinations revealed the presence of blast furnace slag within the internal structure, a homogeneous distribution of reinforcing elements, and the absence of agglomeration. Brinell hardness measurements determined that a 5 wt.% addition of blast furnace slag increased the hardness of the Al6061 alloy by 29.31 %. The greatest increase in hardness, 108.62 %, was observed in the hybrid composite containing 3 wt.% Al2O3, 3 wt.% SiC, and 5 wt.% BFS reinforcements. Fatigue life tests indicated that fatigue life improved with increasing reinforcement. The most significant enhancement in fatigue life, 625.28 %, was observed in the composite reinforced with 3 wt.% BFS, 5 wt.% Al2O3, and 5 wt.% SiC compared to the unreinforced alloy
Examination of ELT Lecturers' Digital Technology Integration Levels Via SAMR Model During Emergency Remote Education
No full textthe present study investigated the digital technology integration levels of the English Language Teaching lecturers during the COVID-19 pandemic emergency remote education conditions via SAMR Model. The study employed a correlational design by employing a Likert-type questionnaire with 243 English Language Teaching lecturers employed at 20 universities geographically dispersed into the seven districts of Turkey. Universities were selected by depending on the statistical data of the Nomenclature of Territorial Units for Statistics. The results showed that synchronous teaching platforms were mainly employed as overhead projectors, which underlined the dominant usage of Substitution level without lecturers' effective interferences to the activities. Transforming either the frame or content of the original materials was also promoted largely under the Modification level but placed after the Redefinition level, which is time and effort-demanding, and promoted densely after the Substitution level. The Augmentation level was the least promoted one since participants were of the opinion that increasing or decreasing the number of robotic activities is less useful than Modification and Redefinition level-appropriate practices. Apart from that, while participants' digital technology integration levels were found related to their gender, background education, and online teaching experiences; seniority and age were not found to be significant indicators of the participants' digital technology integration levels
The Effect of Early-Initiated Half-Swaddling and Kangaroo Care Practices on Maternal Sleep Quality and Postpartum Depression in Term Infants: A Randomized Controlled Trial
No full textThis study aimed to investigate the effects of half-swaddling and kangaroo care practices early initiated in mothers of term babies on maternal sleep quality and postpartum depression. This study was prospective, four-arm randomized controlled trial. This study was conducted in 136 mothers and term baby hospitalized in Trakya University Hospital between April 2023 and August 2024. Participants were randomly divided into four groups using computer program with 34 mothers in each group: control (A), half-swaddling (B), kangaroo care (C), half-swaddling, and kangaroo care (D). Starting, 1st, 2nd, 3rd, and 6th months, the data of all four groups were collected with the Questionnaire Form, Edinburgh Postpartum Depression Scale (EPDS), and Pittsburgh Sleep Quality Index (PSQI). Bonferroni and multiple linear regression (MLR) were used for advanced statistics. C and D groups had more positive effects on depression, while B and D groups had more positive effects on maternal sleep quality (p < 0.001). The combination of half-swaddling and kangaroo care practices early initiated in term babies has a significant effect on reducing the risk of postpartum depression, and half-swaddling practice has an important effect on improving maternal sleep quality.

Psychometric Properties of the Social Attribution Task and Its Relationship With Cognitive Functions
No full textObjective The Social Attribution Task-Multiple Choice (SAT-MC) battery is one of tests used to evaluate social cognitive capacity. This study aimed to examine the reliability and validity of the SAT-MC for the first time in healthy adults and in individuals diagnosed with schizophrenia, then to investigate the effect on SAT-MC performance of clinical variables in schizophrenia patients. Methods The study included 207 volunteers; 157 healthy adults, and 50 individuals diagnosed with schizophrenia. All the study participants were applied with the Raven Standard Progressive Matrices Test (RSPM), the Reading the Mind in the Eyes Test (RMET), and the Results The results of the analyses showed that the SAT-MC had content and criteria validity in both the individuals diagnosed with schizophrenia and in the healthy control group. Internal consistency of test was calculated as McDonald's omega coefficient 0.81, and the test-retest reliability was found to be 0.75. Hierarchical multivariate regression analysis showed a predictive effect of RSPM and RMET on the SAT points. Conclusion The results of this study demonstrated that SAT was valid and reliable in evaluating social attribution skills in both a healthy and a schizophrenia sample group. Social attribution skill was found to be related to the perceptual reasoning and abstract thinking skills of neurocognition. The social cognition dimension was determined to be related to the theory of mind skills. Insufficient social attribution skills, seen especially in schizophrenia patients, can lead to social withdrawal and isolation by disrupting interactions and relationships with others.

Enhanced Thermal Properties of Composite Phase Change Material by Polydopamine-Driven Cu Nanoparticles
No full textParaffin wax (PW) is a typical organic phase change material (PCM) with superior thermal storage performance. However, its poor thermal conductivity, liquid leakage, and inadequate solar absorption have limited its commercial application in thermal management and solar energy utilization. To address these limitations, polydopamine (PDA) was first employed to modify diatomite (DT) to enable uniform deposition of metal Cu nanoparticles on its surface to construct as a DT/PDA/Cu supporting material. Then, the obtained supporting material was used to encapsulate PCM, and the prepared shape-stabilized PCM (SSPCM) with 50 wt.% PW exhibited no leakage, a prominent solar-thermal conversion ability, and a high thermal conductivity. The PW/DT/PDA/Cu SSPCM demonstrated a thermal conductivity of 1.115 Wm-1K-1, which was up to 3.83 times larger than that of pure PW, and a pronounced photothermal conversion efficiency of 88.27%. The substantial performance enhancement can be attributed to the PDA modification-driven strong in situ and uniform deposition of Cu nanoparticles on the surface of DT. Furthermore, the SSPCM was also capable of generating a steady current of 39.3 mA. The study results provide an efficient method for the multiple energy conversion application of SSPCMs.Beijing Natural Science Foundation [L245004]; National Key R&D Program of China [2025YFE0110700]; National Natural Science and Foundation of China [52474445]; West Light Foundation of the Chinese Academy of Sciences; International Partnership Program of the Chinese Academy of Sciences [041GJHZ2024027MI]; Science and Technology Project of Hebei Education Department [ZD2022053]; Funding Projects that guide local for scientific and technological development of Hebei Provincial Department of Science and Technology [236Z4504G]; Post-graduate Innovation Fund Project of Hebei Province of China [CXZZSS2025105]; Kunlun Talents TalentsThis work is financially supported by the Beijing Natural Science Foundation (No. L245004), the National Key R&D Program of China (No. 2025YFE0110700), the National Natural Science and Foundation of China (52474445), the West Light Foundation of the Chinese Academy of Sciences, the International Partnership Program of the Chinese Academy of Sciences (No. 041GJHZ2024027MI), the Science and Technology Project of Hebei Education Department (ZD2022053), the Funding Projects that guide local for scientific and technological development of Hebei Provincial Department of Science and Technology (236Z4504G), the Post-graduate Innovation Fund Project of Hebei Province of China (CXZZSS2025105), and the Kunlun Talents Talents
The life, works, and sufi thought of sheikh Ali Samarqandi
No full textŞeyh Ali Semerkandî, yaşadığı ve uğradığı bölgelerde ihtiyaç duyulduğu ölçüde ilim ve irşat faaliyetleriyle çevresine rehberlik etmiş seçkin şahsiyetlerden biridir. Kimileri sadece kendi döneminde etkili olurken, bazı âlimler hem çağlarında hem de sonraki kuşaklarda değerli eserleri aracılığıyla yaşamaya devam etmişlerdir. Şeyh Ali Semerkandî de etkisini sadece kendi devriyle sınırlamayıp, gelecekteki nesillere de uzanan bir mürşid-i kâmil olarak öne çıkmıştır. Bu durum, onun kalplerde giderek daha fazla kabul görmesine yol açmıştır. Memleketinden başlayarak kutsal mekânlara uzanan bilgi ve maneviyat yolculuğu da bunda büyük rol oynamıştır. Tasavvufî eğitimini tamamladıktan sonra Anadolu'ya gelerek farklı bölgelerde irşat hizmetlerinde bulunması, sonraki devirlerde Şeyh Ali Semerkandî ile Şeyh Alâeddin Ali es-Semerkandî'nin aynı kişi olup olmadığı ve nereye defnedildiği konusundaki tartışmaları da beraberinde getirmiştir. Aynı şekilde bir kataloglama hatası, onun kaleme aldığı "Bahru'l-Ulûm fî Tefsîri'l-Kur'an" adlı eserle ilgili sahiplik tartışmalarının doğmasına sebep olmuştur. Bu çalışmada, Şeyh Ali Semerkandî'nin aslında Şeyh Alâeddin Ali es-Semerkandî ile özdeş olduğunu, bugün "Çamlıdere" adıyla bilinen ve resmî kayıtlarda "Yabanâbâd" olarak anılan bölgede medfun bulunduğunu ve "Bahru'l-Ulûm fî Tefsîri'l-Kur'an" adlı eserin müellifi olduğunu ortaya koyarak bu konudaki bilgi kirliliğini azaltmayı amaçladık.Sheikh Ali Samarqandi was a prominent figure who disseminated knowledge and spiritual guidance wherever needed. While some scholars remained influential only within the confines of their era, others left a lasting legacy through the works they produced. Sheikh Ali Samarqandi was among those whose intellectual and spiritual influence transcended his time, continuing to inspire successive generations. His profound dedication to pursuing knowledge and spirituality—from his birthplace to sacred lands—was pivotal in establishing his enduring presence in the collective memory of communities. After completing his spiritual training, he travelled to Anatolia, undertaking various guiding missions across different regions.Over time, debates emerged concerning the identity of Sheikh Ali Samarqandi, particularly regarding whether he was the same individual as Sheikh Alâeddin Ali as-Samarqandi and the exact location of his burial. Furthermore, confusion surrounding the authorship of his exegetical work Bahru'l-'Ulûm fî Tafs?r al-Qur'?n arose due to cataloguing inaccuracies. This study seeks to clarify that Sheikh Ali Samarqandi and Sheikh Alâeddin Ali as-Samarqandi are indeed the same person, that his burial place is located in the area historically known as Yabanâbâd (modern-day Çamlıdere), and that Bahru'l-'Ulûm fî Tafs?r al-Qur'?n is genuinely his work. In doing so, the study aims to resolve the ongoing ambiguities surrounding his identity and legacy
