Süvari Tasvirli Anadolu Selçuklu Sikkeleri Üzerine Bir Değerlendirme: Bursa Arkeoloji Müzesi Örnekleri
No full textThe cavalry depiction was used by many societies for centuries for its symbolic narrative of power and authority. Due to their nomadic lifestyle and reverence for horsemanship, Turks were particularly drawn to portraying cavalry. This situation is also seen in the coins minted by the sultans and maliks in the Anatolian Seljuks period, when the struggle for the throne was intense. They wanted to convey their messages directly to their rivals by including the composition on the coins they minted. In our study, coins depicting cavalrymen minted during the Anatolian Seljuks period registered in the inventory of Bursa Archaeology Museum were examined and 37 coins were identified. One is made of silver, the others are made of copper. The dates 595 AH and 646 AH were detected on 4 of the coins. The inscription lines include the names of sultans and maliks Kilij Arslan II, Qutb al-Din Malik Shah, Muizz al-Din Kaiser Shah, Ghiyath al-Din Kaykhusraw I, Rukn al-Din Suleiman Shah II, Ala al-Din Kay-Qubad I and Rukn al-Din Qilij Arslan IV. The minting locations are Sivas and Malatya. The coins are decorated with figural, geometric, floral elements. The cavalryman depicted on all coins is in motion with his horse and holding a weapon in one hand. Our study aims at determining the place of this group in Turkish art with reference to Anatolian Seljuks coins depicting cavalrymen registered in the inventory of Bursa Archaeological Museum. © 2025 Elsevier B.V., All rights reserved

Integration of Conductive Additives to PLA-Based Biodegradable Composite Films to Improve Their Electrical, Mechanical, and Physical Characteristics
No full textIn this study, Oltu stone powder (OS) and Fe3O4/mica-based conductive pigment (CP) were compounded with polylactic acid (PLA) to develop bio-based conductive films. Four different concentrations of 1%, 10%, 20%, and 30% of powders were applied to determine their optimal concentration in the PLA matrix. The mechanical, thermomechanical, electrical conductivity, melt-flow, and morphological properties of composite films were reported using the tensile, hardness, and impact tests, dynamic mechanical analyses test, linear four-probe method, and atomic force microscopy (AFM), melt-flow index measurements, and scanning electron microscopy methodology, respectively. According to tensile test results, tensile strength and modulus characteristics of PLA decrease with additive integration. However, the elongation value of PLA declined as OS and CP loadings increased. The maximum tensile performance was attained for composites filled with 20% of both CP and OS. The unfilled PLA's Shore D value rose by including OS and CP. At the same loading levels, carbon-based OS produced comparatively higher hardness values than CP, which comprised iron oxide and alumina silicate. AFM analysis revealed that both CP and OS inclusions caused enhancements in surface roughness as their filling amounts increased. In summary, composite samples exhibiting a 20% loading ratio of both OS and CP showed significantly improved mechanical and thermomechanical performances compared to other composites. Composite films with 1% additives have the potential to be applied in electrostatic packing. Additionally, 3D-printed components can be fabricated using composites for applications where appropriate mechanical resistance and electrical conductivity specifications are required

Çalışmalardan elde edilen veriler “Comprehensive Meta-Analysis (CMA)” programı kullanılarak analiz edilmiştir. Araştırmada meta analiz kapsamına alınan çalışmaların heterojenliğinden dolayı rastgele etkiler modeliyle etki büyüklüğü hesaplanmıştır. Araştırmanın bulguları uyarlanabilir öğrenme ortamlarının akademik başarıya artı etki yaptığını göstermiştirThe primary aim of this study is to systematically compile experimental research examining the impact of adaptive learning environments on students' academic achievement and to synthesize the findings through a comprehensive analysis. To this end, a thorough literature search was conducted across multiple academic databases—including ERIC, Web of Science, ProQuest Dissertations and Theses, the Turkish National Thesis Center (YÖK Ulusal Tez Merkezi), and Google Scholar—using keywords such as adaptive learning environments, academic achievement, and personalized learning. As a result of this screening process, a total of 16 studies meeting the inclusion criteria were identified: 7 doctoral dissertations, 2 master's theses, and 7 peer-reviewed journal articles. For data analysis, the Comprehensive Meta-Analysis (CMA) software was employed, which is widely used to calculate overall effect sizes across multiple data sets in meta-analytical research. Given the heterogeneity among the included studies in terms of sample characteristics and implementation contexts, a random-effects model was adopted. This model accounts for potential variations across studies and allows for more generalizable conclusions. The findings indicate that adaptive learning environments have a statistically significant and positive impact on students' academic achievement. These results highlight the effectiveness of student-centered, flexible learning approaches that consider individual differences, thereby underscoring the pedagogical value of adaptive technologies in education

Design deficiencies, failure modes and recommendations for strengthening in reinforced concrete structures exposed to the February 6, 2023 Kahramanmaraş Earthquakes (Mw 7.7 and Mw 7.6)
No full textAfter two major earthquakes centred in Kahramanmara & scedil; on February 6, 2023, in T & uuml;rkiye, there was significant destruction of the building stock. More than fifty thousand people lost their lives, and many people lost their comfort of life even though they were rescued from the wreckage. Researchers have emphasized that this catastrophic consequence is generally caused by design and production errors and low material quality in almost all building types, especially reinforced concrete, steel, masonry, and prefabricated structures. Within the scope of this study, damage patterns and the design flaws of reinforced concrete structures in Malatya, which is one of the provinces affected by the Kahramanmara & scedil; earthquakes, were examined via a field study. During the fieldwork, it was determined that inadequate longitudinal reinforcement and stirrup reinforcement, in-depth reinforcement, and concrete quality, design errors in the column-beam junction area, ignoring the structure-soil interactions, short columns, torsional irregularity, and soft stories were the main factors that led reinforced concrete buildings to be heavily damaged or collapse. After the root causes of damage to reinforced concrete structures were examined, the measures and applications that should be taken to ensure that reinforced concrete structures can maintain their services in the event of earthquakes that are likely to occur in the future was discussed.Scientific and Technological Research Council of Turkiye (TUBIdot;TAK) [123D026]This study was supported by the Scientific and Technological Research Council of Turkiye (TUB & Idot;TAK), and the project number is 123D026
Optimizing solid solution and ? phase formation: Predictive criteria for Mo-containing high-entropy alloys
No full textThis study establishes a novel set of criteria for predicting the formation of single-phase solid solutions and sigma precipitates in Mo-containing high-entropy alloys (HEAs). Under both equilibrium and non-equilibrium conditions, the formation conditions for face-centered cubic (FCC), body-centered cubic (BCC) solid solutions and sigma phases were comprehensively assessed. These criteria greatly reduce experimental effort by offering a streamlined approach for creating high-performance Mo-containing HEAs and coatings. The criteria were established utilizing thermodynamic factors including mixing entropy (Delta S-mix), mixing enthalpy (Delta H-mix), atomic radius differential (delta), valence electron concentration (VEC), paired sigma-forming elements (PSFE), and average electron holes (N-a). Single-phase solid solutions are formed with the following thermodynamic parameters: 6.81 = 46 %, and 2.40 = 42, 1.73 = 66 %, 2.75 <= Na <= 3.02. These criteria advance the creation of high-performance materials by acting as useful recommendations for forecasting and designing Mo-containing HEAs.National Natural Science Foundation of China [51605230, 52371033]; Key Research and Development and Promotion Special Project (Scientific and Technological Research) in Henan Province, China [232102221022]; Nanyang City Basic and Frontier Technology Research Special Project, in Henan Province, China [23JCQY1001, 23JCQY2013]This work was financially supported by the National Natural Science Foundation of China (51605230, and 52371033), the Key Research and Development and Promotion Special Project (Scientific and Technological Research, No. 232102221022) in Henan Province, China, as well as the Nanyang City Basic and Frontier Technology Research Special Project (Nos. 23JCQY1001 and 23JCQY2013), in Henan Province, China
