Multimarket Contact, Competition, and Performance: An Application to Turkish Deposit Banks
Get PDFThe banking sector plays a pivotal role in financial markets, providing an ideal setting to examine multimarket contact (MMC)-a phenomenon where banks compete against the same rivals across multiple markets. This study investigates how MMC dynamics influence bank risk and performance, particularly in the context of technological advancements and the post-COVID-19 banking landscape. Using panel data from 17 deposit banks operating continuously in the Turkish banking system between 2012 and 2021, the study employs the Generalized Method of Moments (GMM) to analyze the effects of MMC. The findings indicate that MMC intensifies competition in the Turkish banking sector, leading to improved asset quality but negative impacts on profitability, overal performance, and bankruptcy risk. These results suggest that while broader market exposure enhances risk management and credit quality, heightened competition erodes profitability and financial stability. Given the increasing digitalization of banking services and the shift towards branchless banking, regulators and financial institutions should reconsider market expansion strategies, balancing competition with financial sustainability. This study contributes to the literature by offering empirical insights from an emerging market and highlighting the interplay between MMC, financial stability, and technological evolution in banking. The findings hold practical implications for policymakers, regulators, and financial institutions seeking to optimize competitive strategies while ensuring banking sector resilience

Araştırmanın materyalini Özel Edremit Hayvan Hastanesine ve Özel Trakya Hayvan Hastanesine memede kitle şikayeti ile getirilen 12 adet köpek oluşturdu. Olguların üçünün iyi huylu kitle, dokuzunun kötü huylu kitle olduğu tespit edildi. Kötü huylu kitlenin olduğu dokuz olgunun beşinde (%55,5) metastaz varlığının olmadığı buna karşın, dört olguda (%44,5) metastaz varlığının olduğu tespit edildi.
Sonuç olarak memede kitle şikayeti ile gelen hastalarda BT hem medikal hem de cerrahi tedavi için bir yol haritasının belirlenmesinde önem ve gereklilik oluşturmaktadır. Bilgisayarlı Tomografinin toraks ve abdomen bölgesinde farklı bulgular tespit etmesi ve bulguların tedavi sürecine olan etkileri de dikkate alındığında, hasta refahı açısından daha kaliteli ve daha başarılı bir tedavi sürecine etkisi olacağı sonucuna varılmıştır.Studies focusing on metastatic screening in canine mammary tumor cases are relatively limited. The aim of this study was to evaluate the data obtained from computed tomography (CT) scans and findings of 12 dogs diagnosed with mammary tumors.
The study material consisted of 12 dogs that were presented to Ozel Edremit Animal Hospital and Ozel Trakya Animal Hospital with complaints of mammary masses. It was determined that three of the cases had benign masses, while nine had malignant tumors. Among the nine malignant cases, no evidence of metastasis was found in five cases (55.5%), whereas metastasis was detected in four cases (44.5%).
In conclusion, CT imaging in patients presenting with mammary masses plays a crucial role in guiding both medical and surgical treatment planning. Considering that CT can reveal various findings in the thoracic and abdominal regions and that these findings significantly impact treatment decisions, it was concluded that CT contributes to a more effective and higher-quality treatment process in terms of patient welfare

No full textGeleneksel Anadolu kilim motifleri, toplumsal belleğin, kimliğin ve kültürel anlatımın önemli bir yansıtıcısı olmuştur. Ancak çağımızda gelişen teknolojiler ve küreselleşmenin etkisiyle görsel kültürdeki yerini zamanla kaybetmeye başlamıştır. Bu durum, kültürel sürekliliğin kesintiye uğramasına ve geleneksel simgelerin çağdaş sanat pratiklerinden dışlanmasına neden olmuştur. Söz konusu problem, yalnızca motiflerin estetik değerini değil, aynı zamanda taşıdıkları sembolik ve tarihsel anlamların da kaybolasına yol açmaktadır. Bu tez çalışasının amacı, Anadolu kilim motiflerinin kültürel ve simgesel değerini koruyarak, bu motiflerin çağdaş Türk sanatındaki temsillerini incelemek ve sayısal medya araçları ile nasıl yorumlanabileceğini ortaya koymaktır. Bu çalışmada geleneksel kilim sanatı ve hem Türkiye’de hem de dünyada çalışmalarında geleneksel sanatı kullanan sanatçıların eserleri amaçlı örneklem yöntemi ile belirlenmiş, tarihsel süreci, sembolik ve kültürel değerler bağlamında ele alınarak, analiz edilmeye çalışılmıştır. Bu bağlamda veri toplama yöntemleri, Feldman Yöntemi, Panofsky Yöntemi ve Kültürel Analiz Yöntemleri kullanılmıştır.Traditional Anatolian kilim motifs have been a significant site of collective memory, identity, and cultural expression. However, in our age, technology and globalization have begun to lose their place in visual culture. This has led to the disruption of cultural continuity and the exclusion of traditional symbols from contemporary artistic practices. This problem leads not only to the loss of the motifs' aesthetic value but also to the loss of their symbolic and everyday meanings. The aim of this thesis is to collect representations of Anatolian kilim motifs in contemporary Turkish art, while preserving their cultural and symbolic value, and to reveal how they can be interpreted through digital media. This successful traditional kilim art and the products of traditional artists from both Türkiye and the world are being identified and analyzed through purposeful intervals, addressing the formation of symbolic and cultural values. Data collection methods used include the Feldman Method, the Panofsky Method, and Cultural Analysis Methods

The Main Elements of Tatar Language Vocabulary Related to Posthumous Beliefs and Rituals
Get PDFThe issue of death as one of the transitional stages of human life has shaped the worldview of the Tatar people under various influences. Especially in the practices and rituals performed after death, the influences of ancient Turkish religion, various belief systems (shamanism, paganism, etc.), Islam and Christianity are seen together. This situation is also reflected in the vocabulary of Tatar language. In this study, the vocabulary based on posthumous beliefs and rituals in Tatar language is evaluated with a holistic approach based on the words and expressions identified in Tatar literary language and dialects. Words belonging to the Turkish language and Arabic, Persian, Russian quotations were examined and the effects of these religions or belief systems on the vocabulary of the Tatar language were analysed. The words and expressions examined within the scope of four basic sections determined by a thematic classification were handled by making use of numerical data
The impact of different material types on ergonomics in lower extremity exoskeleton construction
No full textThis study examines the effects of materials such as A Glass Fiber, Aluminum Alloy, Stainless Steel, S Glass Fiber, C Graphite, Hexcel, and Thornel on biomechanical performance in the design of lower extremity exoskeletons. Exoskeleton models created using Computer-Aided Modeling software were integrated into the AnyBody Modeling System and combined with a full-body human model to conduct walking simulations. In these simulations, femur and tibia segments were also incorporated into the model to analyze the impacts of the exoskeleton on human movement dynamics in detail. The results reveal that material selection significantly influences joint reaction forces and moments, ground reaction forces, and contact forces. Flexible materials were found to provide greater comfort to the user but demonstrated lower durability performance. Conversely, more durable materials improved overall efficiency by reducing load transfer. These findings emphasize that material selection in exoskeleton design plays a critical role not only in durability and performance but also in meeting ergonomic requirements. This research offers a valuable foundation for developing exoskeleton designs tailored to different user groups and highlights the need to customize material selection to optimize biomechanical performance. The study serves as a guide for enhancing the compatibility of exoskeletons with human movement dynamics and improving user comfort. © 202

Investigation of Wear Behaviour of Dublex-Coating Treated AISI 1040 Steel
No full textMaterial surfaces used in technological applications must be functional for desired performance. Nickel deposition is used extensively in industrial sectors due to its high corrosion resistance. This coating is one of the oldest surface protection methods used in the decorative applications of steels. However, wear properties of this coating are poor and this case restricts the use of Ni coating. With the development of engineering sciences in technology, the needs for materials with high corrosion and wear resistance are increasing. The demand for increased performance of industry has forced the use of duplex coated metals and duplex surface treatments applied on metals increasingly become widespread. One of these duplex surface treatments is Ni-B and Ni-Si-B coating systems. In these processes, boriding surface treatments, followed by Ni coating, were performed and multi-layer coatings were obtained. In this study, a duplex structure was obtained by box boronizing process on Ni coated by electrochemical method surfaces on AISI 1040 steel. The analyses of the formed layers were made using X-rays, optical and SEM (Scanning Electron Microscope) microscope. Boride layers were investigated in terms of friction, wear, and microhardness properties. The best wear properties were obtained for the sample borided at 900 degrees C for 6 h. Wear tests showed that boriding at 900 degrees C for 6 h and 900 degrees C for 6 h followed by Ni electroplating improved the wear resistance

Do Remittances Lead to Financial Instability? Evidence from Selected Asia-Pacific Countries
Get PDFThe Asia-Pacific region is among the top recipients of international remittances globaly. This study examines the impact of remittances on financial instability and investigates whether the causal relationship between remittances and financial instability is symmetric or asymmetric in selected remittance-dependent Asia-Pacific countries: Pakistan, the Philippines, and Sri Lanka. Using the frequency domain causality approach and monthly data (Pakistan: 2005m01-2023m08; the Philippines: 1998m10-2023m08; Sri Lanka: 2015m01-2022m12), the results reveal both symmetric and asymmetric unidirectional causality from remittances to financial instability in Sri Lanka. In Pakistan, symmetric and asymmetric causality is observed from financial instability to remittances. No significant symmetric or asymmetric causal relationship is found in the Philippines. These findings suggest that recognizing asymmetric effects is essential for designing targeted policy responses in remittance-dependent economies. In particular, strengthening formal remittance channels, enhancing financial sector resilience, and using foreign exchange interventions in crisis-prone contexts like Sri Lanka can help mitigate remittance-induced instability
