Article Elasto-Plastic Phase-Field Modeling of Fracture in FDM-Printed ABS Components: Numerical Implementation and Experimental Validation(Taylor and Francis Ltd., 2025) Dengiz, C.G.; Yorulmazlar, B.; Dorduncu, M.; Taşdemirci, A.This study presents a computational framework for predicting fracture behavior in 3D-printed acrylonitrile butadiene styrene (ABS) components using an elasto-plastic phase-field approach (PFA) implemented within the ABAQUS finite element environment. A user-defined element (UEL) subroutine is employed to solve the coupled displacement and damage equations through a staggered scheme. The model captures crack initiation and propagation under various stress states and specimen configurations, including pure shear, oblique shear, and tensile loading, without requiring predefined crack paths or remeshing. Numerical predictions are validated against experimental results, showing strong agreement in both force–displacement response and failure morphology. Parametric studies are conducted to assess the influence of mesh size, time increment, length scale parameter, and critical energy release rate on fracture response. The results demonstrate that while the peak reaction force is largely insensitive to these parameters, displacement at fracture and damage localization are significantly affected. The calibrated model successfully captures elasto-plastic fracture evolution in printed ABS specimens, confirming its robustness and generalizability. The proposed framework offers a reliable tool for failure analysis of polymer-based additively manufactured components and establishes a foundation for future extensions involving anisotropy, fatigue, and microstructural heterogeneity. © 2025 Taylor & Francis Group, LLC.Article Design Strategies to Optimize Polymeric Vectors for mRNA Delivery(Taylor and Francis Ltd., 2025) Turhan, Z.Y.; Savaş, M.; Alakbarov, A.; Bulmus, V.mRNA holds great promise for preventing and treating a variety of diseases, from infectious diseases to diverse cancers, owing to its transient expression, lack of genomic integration, and scalable production. Among non-viral vectors, polymeric carriers are attractive due to their synthetic versatility and stability, which allow for precise tuning for efficient mRNA delivery. Their scalability further supports the applicability of polymeric vectors. Studies have addressed the room for improvement in polymeric systems for mRNA delivery and have adapted varying approaches depending on the type of polymeric structure, including but not limited to PEGylation, hydrophobic modification, and incorporation of responsive or targeting moieties. This review summarizes advances in polymeric vectors for mRNA delivery and highlights how distinct structural modifications influence toxicity, mRNA transfection efficiency, biodistribution, intracellular trafficking and immune activation, providing a framework for the rational design of next-generation polymeric vectors that can fully realize the clinical potential of mRNA therapeutics. © 2025 Taylor & Francis Group, LLC.Article From Work to Leisure: ”Transforming Kitchen Spaces, Technologies, and Practices in Türkiye, 1930s-2020s.”(Taylor and Francis Ltd., 2025) Emgin, B.; Bektaş Ata, L.; Karaosmanoğlu, D.Kitchens are more than functional spaces; they reflect and shape cultural values, technologies, and ideals of modern life. Framing the kitchen as an orchestrating concept that brings together images, materials, and competencies, this article examines how idealized settings and tools have produced shifting narratives of modernity and redefined meanings, functions, and everyday practices in Türkiye from the 1930s to the present. It highlights the transformation of the kitchen from a moralizing space to one of entertainment and creativity across three eras: the ordered workshop of the 1930s, the cozy living room of the 1970s, and the technological hub of the 2000s. Drawing on archival research from a larger project on the social history of domestic technologies in Türkiye, the article analyzes newspapers, magazines, TV commercials, social media, and films to reveal how domestic ideals have been negotiated through kitchen spaces. © 2025 Informa UK Limited, trading as Taylor & Francis Group.Article Industrial History and Heritage of the Karaburun Mercury Mining District, Türkiye(Taylor and Francis Ltd., 2025) Yılmazer, Aslıhan; Gönülal, Yasemin Özcan; Yüceer, HülyaMining metallic resources has been important to technological advancement since prehistoric times and has contributed to the progress of civilisation. Mining heritage includes sites and structures related to mining that reveal historical and cultural insights. The remains of structures in the mercury mining district on the Karaburun peninsula of Izmir in Türkiye, which includes the Kalecik, Karareis and Dikencik mines, is one such site. Despite its abandonment and subsequent damage, research has highlighted the importance of the district during the late Ottoman empire and the early years of the Republic as a source of cinnabar, the most common source ore for refining elementary mercury. Comparable mines elsewhere have been transformed into heritage sites and tourist attractions, such as at Monte Amiata in Italy and Idrija in Slovenia. In view of the potential, this study aimed to establish the historical and industrial significance of the Karaburun mercury mining district through detailed research and site survey to form a robust base for a holistic conservation approach. © 2025 Elsevier B.V., All rights reserved.Article On-Site Measurements of Temperature and Humidity Conditions for the Comparison of Urban and Rural Sub-Spaces of Traditional Settlements: Historical City of Muğla, Turkey(Taylor and Francis Ltd., 2024) Timur,B.A.; Başaran,T.; İpekoğlu,B.One of the significant processes that ensures realistic determination of the energy needs of historical buildings is case-specific definition of their local microclimatic conditions. Accordingly, the aim of this study is to determine differences for the parameters of temperature and humidity in urban and rural sub-settlements of the historical city, Muğla/Turkey. Study method consists of on-site measurements of these variables in sub-settlements for comparisons. As a result, it was identified urban zone shows heat island characteristics with warmer, drier, and more stable conditions; while rural sub-settlement remains cooler, more humid, and more erratic. In parallel, calculated extents of these differences demonstrate the significance and necessity of on-site measurements and consequential microclimatic zoning of historical cities as conservation/planning tools for responding to the thermal needs of architectural heritage. A key application of these processes would be the establishment of local databases of case-specific weather data to be used in thermal simulation assessments. © 2023 Taylor & Francis.Conference Object Detection of Urban Change Using Remote Sensing and Gis: Izmir Case(Taylor and Francis Ltd., 2008) Tarhan, Çiğdem; Arkon, Cemal; Çelik, M.; Gümüştekin, Şevket; Tecim, V.This study is an example of how land use changes could be detected via high resolution remotely sensed data. In order to perform "change detection" IKONOS satellite images, belonging to 2001 and 2004, have been used. An automated Graphical User Interface (GUI) has been created for detection of environment. Different image enhancement techniques and a fuzzy inference system have been combined in the GUI. The detection results are classified according to some basic levels such as 20-50% and 70%. Additionally, four different change detection algorithms have been applied which are pixel-based, object based, feature based. These algorithms have been examined according to change detection levels with different image enhancement techniques. At the end of the study, the results have been compared.Conference Object Citation - Scopus: 5High Arsenic Levels in Water Resources Resulting From Alteration Zones: a Case Study From Biga Peninsula, Turkey(Taylor and Francis Ltd., 2010) Baba, Alper[No abstract available]Book Part Nucleic acid biochemistry: Food applications(Taylor and Francis Ltd., 2010) Kurnaz, Işıl A.; Ceylan, Çağatay[No abstract available]Book Part Teaching a Regional Landscape Project Studio in the Interdisciplinary Setting(Taylor and Francis Ltd., 2019) Kaplan, Adnan; Velibeyoğlu, KorayRegional and urban landscapes in the age of the Anthropocene need to support recognition of complex and dynamic ecosystems. Water-based regional context and its transformative power at regional and urban scales have been themed on landscape studios of some scholarly works such as G. M. Kondolf et al. and S. Nijhuis and D. Jauslin. The interdisciplinary ‘regional landscape project studio’ follows a didactic approach that combines regional planning and specific mode of regional and urban transformation thinking. The whole idea of the graduate studio is, therefore, to apply landscape infrastructure and the fourth nature into ‘the regional landscape-urban transformation’ equilibrium, as a novel way to healing our living environments. Landscape infrastructure is being explored in urban studies as a concept/reality that expands the traditional set of spatial planning and design strategies towards the multifunctional system. The association of hydrological pattern with natural and urban landscapes calls for site-specific design interventions in some critical cross-section.
