Isıl konforu ve enerji tasarrufunu artırmak için bina kabuğunda faz değiştiren malzeme ve ısı yalıtımının birleşik kullanımı
No full textThe combined use of phase change material (PCM) and thermal insulation (TI) is a crucial opportunity to enhance the thermal performance of buildings. This study aims to determine the optimum location and thickness of PCM and TI, as well as the melting temperature of PCM, in the exterior walls of an educational building located in five climate regions of Türkiye, and proposes a combination of PCM and TI techniques to reduce its cooling energy demand. Antalya, Istanbul, Ankara, Van, and Erzurum were selected to represent the various climatic regions of Türkiye. The simulation results revealed that the combined use of PCM and TI could effectively reduce the interior temperature (ITR) and provide better thermal comfort than incorporating PCM alone. The exterior wall type with PCM in the innermost layer and TI in the outermost layer was the most effective configuration for reducing the temperature fluctuations and cooling energy demand. The optimum melting temperature of the PCM was determined to be 27 ºC, ensuring a higher ITR and lower cooling energy consumption. The combined use of PCM (30 mm) and TI (10 mm), when properly selected according to local climatic conditions, can achieve considerable energy savings (9.12-19.95%).Faz değiştiren malzeme (PCM) ve termal yalıtımın (TI) birlikte kullanımı, binaların termal performansını artırmak için önemli bir fırsattır. Bu çalışma, Türkiye'nin beş iklim bölgesinde yer alan bir eğitim binasının dış duvarlarında PCM ve TI'nin optimum yerleşim ve kalınlığını ve PCM'nin erime sıcaklığını belirlemeyi amaçlamış ve PCM ve TI'nin birlikte kullanım teknikleriyle soğutma enerji talebinin azaltılmasını hedeflemiştir. Antalya, İstanbul, Ankara, Van ve Erzurum, Türkiye'nin çeşitli iklim bölgelerini temsil etmek üzere seçilmiştir. Simülasyon sonuçları, PCM ve TI'nin birlikte kullanımının iç sıcaklık düşüşü (ITR) sağladığını ve yalnızca PCM kullanımına kıyasla daha iyi termal konfor sunduğunu göstermiştir. PCM'nin en içte ve TI'nin en dışta yer aldığı dış duvar tipi, sıcaklık dalgalanmalarını ve soğutma enerji talebini azaltmak için en etkili yapılandırma olmuştur. PCM'nin optimum erime sıcaklığı 27 ºC olarak belirlenmiş, bu da daha fazla ITR ve daha az soğutma enerjisi tüketimi sağlamıştır. PCM (30 mm) ve TI (10 mm) birlikte kullanımı, yerel iklim koşullarına göre uygun şekilde seçildiğinde %9,12-19,95 arasında önemli enerji tasarrufu oranları elde edebilir

From opera to canvas: The philosophical foundations of the relationship between Wagner and Cezanne
No full textCézanne ve Wagner kendi dönemlerinde sert eleştirilere maruz kalmış ve alanlarına kattıkları yeniliklerin değeri ancak sonradan kavranabilmiş olan öncü sanatçılardır. Resim ve müzik gibi iki farklı sanat dalının kesişimi açısından ufuk açıcı bağlantılar keşfedebilmemize imkân veren eserleri, onların sadece akademik anlamda sanata yaptıkları katkılarla sınırlı kalmadıklarını, fakat aynı zamanda kendilerini filozoflara yaklaştıran felsefi tavrın izlerini de taşıdıklarını göstermektedir. Onların bu denli bir yaratıcılığın öncüsü olmalarının sebebi, eserlerinin ardında gizli olan metafizik, fenomenolojik ve varoluşsal unsurlardır. Yaşamın tüm kültürel, bilimsel ya da tarihsel kavrayışlarının sahip olduğu ussallığa öncel olan hakiki anlamını yansıtmayı hedefleyen bu iki sanatçıyı birbirlerine yakınlaştıran da bu arayışa uygun bir yöntem geliştirmek zorunda kalmış olmalarıdır. Bu çalışmanın amacı, Cézanne ve Wagner arasındaki benzerlikleri ortaya çıkararak Cézanne’ın Wagner’de bulduğu yöntemsel yenilikleri resimlerinde nasıl uyguladığını gösterebilmektir. Bu bağlamda öncelikle Cézanne’ın eserlerinin ardındaki felsefi amaca değinilerek, bu amacın eserlerinde nasıl somutlaştığı incelenecek ve sonrasında Wagner’in müzikteki devrimsel keşiflerinin felsefi alt yapısı ile Cézanne’ın yöntemindeki yeri aydınlatılmaya çalışılacaktır. Wagner’in disonans yapıya vurgusuyla tonalite karşısında atonaliteyi çağrıştıran ve alışılagelen armonik yapıyı yıkarak geleneksel diyatonik sistemin sonuna işaret eden müziğinin Cézanne üzerindeki etkisi ortaya konulacak ve böylelikle Cézanne’ın tablolarında Wagnerci modülasyon sisteminin resimdeki karşılığı olan bir renk modülasyonunun bulunduğu gösterilecektir.Cézanne and Wagner were pioneering artists who were subjected to harsh criticism in their time and the value of the innovations they brought to their fields was only understood later. Their works, which allow us to discover stimulating connections in terms of the intersection of two different branches of art such as painting and music, show that they are not only limited to their academic contributions to art, but also carry the traces of the philosophical attitude that brings them closer to philosophers. The reason of being the pioneers of such creativity is undoubtedly the metaphysical, phenomenological and existential points hidden behind their works. What brings these two artists, who aim to reflect the true meaning of life, which is prior to the rationality of all cultural, scientific or historical understandings, closer to each other is that they had to develop a method suitable for this search. The aim of this study is to reveal the similarities between Cézanne and Wagner and to show how Cézanne applied the methodological innovations he found in Wagner in his paintings. In this context, first of all, the philosophical purpose behind Cézanne’s works will be touched upon, how this purpose is embodied in his works will be examined, and afterwards, the place of the philosophical base of Wagner’s revolutionary discoveries in music and Cézanne’s method will be tried to be elucidated. The influence of Wagner’s music on Cézanne, which evokes atonality over tonality with its emphasis on dissonance structure and points to the end of the traditional diatonic system by destroying the usual harmonic structure, will be revealed and thus it will be shown that there is a color modulation in Cézanne’s paintings that is the equivalent of the Wagnerian modulation system
Enhanced vibration detection with rgo-doped pan/pvdf molecularly blended nanofibers: Preparation and characterization of the nanofibrous flexible piezoelectric vibration sensing elements
No full textIn this study, the reduction process of both GO and GO-doped nanofibers was carried out via the chemical reduction method by using L-ascorbic acid (LAA) and sodium borohydride (SB). GO and reduced graphene oxide (rGO) doped polyacrylonitrile (PAN), polyvinylidene fluoride (PVDF), and PAN/PVDF nanofiber surfaces were produced by the electrospinning method. Nanofiber-reinforced flexible piezoelectric vibration sensing elements with a polydimethylsiloxane (PDMS) matrix were produced from all sample combinations. Piezoelectric vibration sensing element analysis of each sample group was performed. It has been shown that reducing graphene oxide while inside nanofiber surfaces effectively increases the piezoelectric performance of the sensing element. It was observed that when PAN and PVDF were molecularly blended and used together in nanofibers, the output voltage increased significantly by supporting and strengthening each other's piezoelectric properties with the synergistic piezoelectric effect catalyzed by GO addition and a subsequent reduction process. This effect was highest with 1.98 V for the PAN/PVDF blend, where incorporated GO was reduced by 50 mM SB (PAN/PVDF/ GO)50SB. According to the Raman results, the lowest intensity ratio of the D and G band (ID/IG) among the sample group containing PAN/PVDF/GO was 0.992 for the (PAN/PVDF/GO)50SB sample. Correspondingly, the maximum reduction was also in this sample. XPS results showed that C/O ratios were 16.35 and 43.21, respectively, for PAN/PVDF/GO nanofibers that were reduced separately with LAA and SB. Thus, SB provided a better reduction in the removal of oxygen functional groups. The developed flexible piezoelectric vibration sensing element can be used for the detection of dynamic loads on frames of an aircraft or in developing wearable technologies for pilots

Clinical and molecular findings in actin-related inborn errors of immunity: the middle East and North Africa registry
No full textBackground The majority of monogenic inborn errors of immunity presenting as actinopathies were reported originally from the Middle East and North Africa (MENA) countries indicating a high prevalence of these entities in the region. However, their prognosis is unclear due to rarity and lack of comprehensive treatment outcomes.Methods We evaluated clinical, immunological, and genetic abnormalities associated with 15 genetic entities of actinopathies. Based on the function of mutant genes in actin-regulatory pathways, patients were classified into CDC42- and RAC2-related subcategories.Results A total of 503 individuals (29.5% females) from 17 countries were considered with a median age of 120 months. Although most patients presented initially with allergic phenotypes (37.7%), the most prevalent manifestations throughout the lifespan were infection in respiratory tracts (72.2%). Primary clinical diagnosis was mainly combined immunodeficiencies (48.3%) and the majority of cases were molecularly assigned to the CDC42 pathway (64.8%). The most common genetic defects were reported within the DOCK8 (n = 209) followed by the WAS (n = 94) and the CARMIL2 (n = 15) genes. Hematopoietic stem cell transplantation (HSCT) was conducted on 24.0% of patients, which significantly improved survival in patients with defects in WAS, DOCK8 and DOCK2. Overall mortality was 23.0%, mainly due to sepsis and malignancy.Conclusion Patients with defects in RAC2-associated regulators of actin usually present with late-onset symptoms due to normal immune profiles, but a higher rate of EBV and HPV infections, autoimmune cytopenia, asthma, and lymphoproliferation compared to defects in the CDC42 pathway. The severity of mutations in patients of the CDC42 group helps to estimate the prognosis of the disease and prioritization of HSCT
Ankylosing spondylitis and kinesiophobia
No full textBackground Ankylosing spondylitis (AS) is a chronic rheumatic disease that predominantly affects the axial skeleton, causing pain and functional impairment. Kinesiophobia, or fear of movement, is common in patients with chronic pain conditions and can significantly hinder treatment outcomes. This study aims to assess the level of kinesiophobia in AS patients and explore its relationship with demographic characteristics, disease duration, pain intensity, disease activity, and functional impairment. Methods This single-center study included 35 AS patients from July 2021 to July 2023. Patient demographics, disease duration, disease activity (BASDAI (Bath Ankylosing Spondylitis Disease Activity Index)), functionality (BASFI (Bath Ankylosing Spondylitis Functional Index)), pain intensity (VAS (Visual Analog Scale)), and kinesiophobia (TSK (Tampa Scale of Kinesiophobia)) were recorded and analyzed. Patients were categorized into low and high kinesiophobia groups based on TSK scores. Results Of the 35 AS patients, 15 (42.86%) had high kinesiophobia levels (TSK >= 37). Patients with high kinesiophobia had significantly higher BASDAI, BASFI, and VAS scores (p 0.05). Conclusion High levels of kinesiophobia in AS patients are associated with increased pain, disease activity, and functional impairment. Early interventions targeting kinesiophobia could improve treatment outcomes and patient functionality

No full textThis paper introduces an improved optimization algorithm based on migration patterns of greylag geese, known for their efficient flying formations. The Modified Greylag Goose Optimization Algorithm (MGGOA) is modified by augmenting the levy flight mechanism and artificial neural network (ANN) strategies. The algorithm is detailed, presenting mathematical formulations for both phases. Subsequently, the paper applies the MGGOA to various engineering optimization problems, including heat exchanger design, car side impact design, spring design optimization, disc clutch brake optimization, and structural optimization of an automobile component. Statistical comparisons with benchmark algorithms demonstrate the efficacy of MGGOA in finding optimal solutions for these design engineering problems
The phenomena of criticism in the mutawatir qiraat (the first four centuries of the hijri)
No full textThis dissertation provides an in-depth examination of the phenomenon of criticism in the field of qiraat that emerged during the first four Hijri centuries. The revelation of the Qur'an in seven aḥruf laid the foundation for the diversity of qiraat based on different dialects and modes of pronunciation. Over time, this diversity attracted the attention of scholars, leading to varying approaches regarding the acceptance or rejection of certain qiraat. This study meticulously analyzes the reasons behind the criticism of qiraat and the responses of scholars of recitation to these critiques. The research is structured into two main sections. The first section explores the lexical and terminological meanings of tenkit in the field of qiraat. It further examines the historical factors that influenced the emergence of qiraat criticism, including the issue of seven aḥruf, The Final Presentation, the compilation and transcription of the muṣḥaf, the criteria for the acceptance of a qiraat, and Ibn Mujahid's standardization of qiraat to seven canonical readings. Additionally, the views of prominent scholars involved in the critique of qiraat, such as Abu Amr al-Basri, Yahya b. Ziyad al-Farra, Abu Ubayd al-Qasim b. Sallam, and Ibn Jarir al-Tabari, are critically evaluated. The second section details how qiraat were criticized based on the reliability of their transmitters, their conformity to Arabic linguistic principles, and their consistency with the rasm of the Mushaf. The rawi’s retention ability, adherence to transmission discipline, compatibility of the qiraat with Arabic dialects, and their alignment with syntax and morphology rules are analyzed. Furthermore, critiques related to potential contradictions with the rasm of the muṣḥaf are discussed, along with the scholarly responses to these critiques. In conclusion, this study demonstrates that criticism of qiraat is not merely an academic debate but plays a crucial role in the preservation of the Qur'an. By providing a solid foundation for future research in the field of qiraat, this dissertation aims to make a significant contribution to the defense of the authenticity of the Qur'an and the validation of its qiraat.This dissertation provides an in-depth examination of the phenomenon of criticism in the field of qiraat that emerged during the first four Hijri centuries.

Predictive modeling and chemometric optimization in natural dyeing systems: An analytical case study of wool dyeing with Melissa officinalis l
No full textThis study introduces a robust chemometric framework that integrates predictive modeling and multi-criteria decision-making for the analytical assessment of natural dye systems. Using Melissa officinalis L. as a model extract, we demonstrate an eco-conscious dyeing application on wool yarns evaluated through objective colorimetric parameters. A total of 40 treatment combinations involving bio- and metal mordants were assessed. The Weighted Aggregated Sum Product Assessment (WASPAS) method was used to rank treatments based on L*, a*, and b* values, identifying the Cu-GA combination as optimal with a composite score of 1.71. To model dyeing behavior, we implemented a feedforward Artificial Neural Network (ANN) trained on 3720 K/S data points across treatment and wavelength conditions. The ANN achieved high predictive accuracy (R2 = 94.13-95.28; MSE = 1.37-1.95) using Levenberg-Marquardt backpropagation. This model enabled the interpolation of unmeasured color strength values, enhancing reproducibility and reducing experimental load. UV protection was also evaluated, with the Cu-GA treatment achieving a maximum UPF of 128.43. Enhanced wash, rub, and light fastness in Fe and Cu mordanted samples were explained via coordination bonding between dye chromophores and fiber. These results demonstrate how machine learning and decision science tools can generalize analytical predictions in dye systems. The integrated ANN-WASPAS framework offers a transferable analytical strategy applicable to broader natural product formulations, quality control, and sustainable materials research
