Öğe Türü: Öğe , Historical Overview of Kalenderhane Mosque (4th-Century Church): Characterization of Its Frescoes Using a Multi-Analytical Approach(Romanian Inventors Forum, 2025) Ceran, İrem; Kaygısız, Ersin; Özbaş, FatihThis study aims to characterize the frescoes located in the basement of a historically significant building that was originally constructed as a church (Theotokos Kyriotissa) and is now functioning as a mosque (Kalenderhane). The research employs multiple analytical methods, including X-Ray Diffraction (XRD), Fourier-Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy with Energy Dispersive X-Ray Spectroscopy (SEM-EDS), to investigate the material composition and preservation state of the frescoes. The results indicate significant interactions between environmental factors and the preservation state of the frescoes, highlighting the importance of ongoing conservation efforts. This study contributes to a deeper understanding of the frescoes' historical context and their significance in the architectural heritage of the site. Additionally, it provides recommendations for future research and restoration practices aimed at preserving this invaluable cultural artifact.Öğe Türü: Öğe , Revisiting Trend Stability Using Mann-Kendall andWilcoxon Signed-Rank Tests Through Innovative Method Comparisons(MDPI, 2025) Kesgin, Remziye İlayda TanUnderstanding the persistence and stability of hydroclimatic trends is essential for climate adaptation and sustainable water resource management, particularly in Mediterranean regions characterized by irregular precipitation regimes. This study examines long-term rainfall variability (1974–2021) at six meteorological stations along the southern coasts of Türkiye using three complementary non-parametric techniques: the Mann-Kendall (MK) test, theWilcoxon Signed-Rank Test (WT), and the Innovative Trend Analysis (ITA). The three tests were applied with their respective methodological extensions to enhance sensitivity and better capture trend stability. Results show that while most stations exhibit generally stable rainfall regimes, period- and location-specific variations with non-monotonic or oscillatory tendencies are present, revealing patterns that standard trend tests often fail to detect. The WT method was more responsive to short-term fluctuations, whereas ITA and its three-dimensional version (3D-ITA) provided valuable insights into trend persistence and stability. Overall, the findings highlight that trend stability assessment enables the distinction between transient climate variability and sustained hydroclimatic change, offering a stronger scientific basis for adaptive water management and regional sustainability planning under climate uncertainty.Öğe Türü: Öğe , Abrank Surp Tavit Monastery: Documenting, Conserving, and Rehabilitating a Threatened Armenian Cultural Heritage Site in Eastern Anatolia(MDPI, 2026) Can, Ayşenur Yelda; Esmer, MineAbrank Surp Tavit Monastery, situated near Üçpınar Village in Erzincan’s Tercan district, Eastern Anatolia, Turkey, stands as a significant yet critically endangered example of Armenian monastic heritage. This article presents a comprehensive study based on original data from fieldwork and archival research, documenting the monastery’s complex history, intricate architectural fabric, current state of preservation, and proposing conservation strategies alongside a sustainable adaptive reuse plan. Combining terrestrial laser scanning and droneassisted photogrammetry, the research provides unprecedented detailed documentation of the partially standing cruciform church, chapel, khachkars (UNESCO-listed Armenian cross-stones), and ruined auxiliary structures. Historical analysis traces the site’s evolution from a pre-Christian religious center through its foundation (traditionally attributed to St. Gregory the Illuminator), 19th-century restoration, and subsequent abandonment. The monastery faces imminent loss due to structural instability, material decay, environmental factors, and human-induced damage like looting and vandalism. Emphasizing minimal intervention and material compatibility, the conservation proposal includes structural stabilization, material consolidation, and sensitive reintegration of lost elements. Crucially, the study advocates for adaptive reuse as a “Monument Museum” and open-air exhibition, respecting the site’s spiritual legacy while ensuring its preservation and accessibility. This work fills a critical gap in the conservation of Armenian heritage in Turkey and offers a model for safeguarding similar endangered sites.Öğe Türü: Öğe , Effect of Scanning Speed on Microstructure, Hardness, and Corrosion Behavior of Additively Manufactured 316L SS in a Chloride-Rich Environment(Springer Nature, 2025) Yılmaz, Halil; Tarakçı, Gürkan; Özer, Gökhan; Budak, Hasan Feyzi; Alkan, Bülent316L stainless steel is widely used in chemical processing, shipbuilding, medical implants, and nuclear components due to its excellent corrosion resistance and mechanical performance. In this study, selective laser melting (SLM) was employed to fabricate 316L stainless steel under various laser scanning speeds (600-1000 mm/s) to investigate the combined effects on microstructure, porosity, hardness, and corrosion behavior. Results show that higher scanning speeds promote microstructural refinement and increase hardness, reaching 372.4 HV for the AB1 condition, but also lead to increased porosity. Electrochemical tests in 3.5 wt.% NaCl solution revealed that corrosion resistance improves at lower scanning speeds, with the AB5 sample achieving a corrosion current density of 2.722 3 1028 A cm22 and a polarization resistance of 93.97 3 104 X cm2, outperforming even wrought 316L stainless steel. This study demonstrates that controlling scanning speed enables a balance between strength and corrosion resistance, providing valuable insights for additively manufactured 316L components in demanding industrial environments.Öğe Türü: Öğe , Development and Validation of the Post-Bereavement Growth Scale (PBGS): A Turkish Sample Study(Routledge, 2025) Kaya, Muhammet Enes; Kumova, FilizThe loss of a close one is commonly construed as a painful experience and addressed predominantly in terms of its pathological aspects. However bereaved individuals may also experience psychological growth following loss. The present study examined the experience of loss from a multidimensional perspective, developing the Post‑Bereavement Growth Scale (PBGS). Participants, 335 adults aged 18–65 who experienced the death of a close one between 3 and 24 months prior, answered the questions online. Additionally, as part of the validity analyses, they also completed measures of personal development and meaninglessness-emptiness. For reliability analyses, 30 participants completed the PBGS twice, 4 weeks apart. The psychometric evaluation of the PBGS yielded a 26‑item, five‑factor structure. Subscales were Functioning, Personal Resources, Relational Coping, Making Sense of Life, and Adaptation. The findings indicated that the PBGS possesses satisfactory validity and reliability.
