Article A Novel Approach by Combining Fuzzy Ahp and a Simulation Model To Analyze Suitability of Ports for Offshore Wind Farms(int Soc offshore Polar Engineers, 2025) Ozturk, Samet; Karipoglu, Fatih; Efe, BurakThis study presents a comprehensive suitability analysis for assessing the serviceability of existing container ports for offshore wind farms (OWFs) in Turkey, utilizing a combination of fuzzy analytical hierarchy process with Arena simulation modeling. This study is the first comprehensive analysis of offshore wind port infrastructure that integrates a multi-criteria decision making process with an Arena simulation model tailored specifically for existing container ports. The results indicate that technical criteria are deemed most critical, carrying the highest weight (0.563), with expansion potential identified as the most impactful criterion within the technical category. In addition, the study employs the Arena simulation software to forecast the operational workload on the most suitable ports following potential OWF installations.Book Part Medical Geology Outreach: a Major Success Story From Turkey(Springer International Publishing, 2021) Baba,A.; Finkelman,R.B.It is incumbent upon medical geology practitioners to reach out to students, science faculties, decision makers, and the biomedical/public health communities to promote this emerging discipline. Perhaps the most successful of these efforts have taken place in Turkey where medical geology courses have been offered in four medical and ten engineering faculties. As a result of these outreach efforts by the Turkish medical geology community for the past decade, there has been robust interactions with scientists from many disciplines and collaborative research on groundwater quality, asbestos, radon, arsenic, mesothelioma, fluorosis, etc. © Springer Nature Switzerland AG 2021.Book Part Citation - Scopus: 8Secondary Metabolites From Turkish Astragalus Species(Springer International Publishing, 2019) Gülcemal,D.; Aslanipour,B.; Bedir,E.The genus Astragalus belonging to the Leguminosae family is a widely distributed plant throughout the temperate regions of the world. This plant species is used in various traditional and folklore medicines for the treatment of nephritis, diabetes, and uterine cancer and as antiperspirant, diuretic, and tonic. In Turkish folk medicine, the aqueous extracts of some Astragalus species are used to treat leukemia as well as for wound healing. The present chapter shall discuss about the secondary metabolites extracted from this plant species along with their uses in eradicating various ailments. © Springer Nature Switzerland AG 2019.Article Citation - WoS: 1Citation - Scopus: 5Exploring Student Information Management System Adoption Post Pandemic: Case of Turkish Higher Education(Elsevier Ltd, 2024) Daim,T.; Ozdemir Gungor,D.; Basoglu,N.; Yarga,A.; VanDerSchaaf,H.Many aspects of our lives have changed during the pandemic including the accelerated adoption of technologies. Education was one of the segments that was disrupted by the pandemic, therefore Student Information Systems became critical at that time. This paper explores the adoption of Student Information Management Systems in multiple Turkish universities. The research model was adopted from a study conducted in the US, which is based on the Unified Theory of Acceptance and Use of Technology. More than three hundred students from seventeen universities responded, and the results indicated key factors of adoption. Furthermore, differences with the case in the US were identified. © 2024 Elsevier LtdArticle 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.Article Citation - WoS: 7Citation - Scopus: 9Politics of Waiting for Transformation in Protracted Urban Renewal Projects in Turkey(Sage Publications Ltd, 2023) Ay, Deniz; Penpecioglu, MehmetThis paper explores the politics of 'waiting' as a mode of governance in large-scale urban redevelopment projects. In designated renewal areas, residents/landowners are often subject to several episodes of waiting: waiting for the public authority for information on redevelopment visions; waiting for the plans and projects to become public; waiting for the court ruling if they appeal the plans; waiting for demolition upon plan approvals; and, finally, waiting for the constructions to be completed. Given the complexity of actors and institutions involved in the waiting, it becomes a conflictual political process. This prolonged waiting leads to an ongoing temporariness and precarious spaces of urban renewal. The course of waiting affects the reorganization of the city space now and in the future. We analyze two protracted urban renewal projects from Turkey, Fikirtepe in Istanbul and Karabaglar in Izmir, to explore how residents' decade-long waiting for urban change are shaped and how these diverse waiting experiences lead to different outcomes for the progression of the state-imposed urban renewal agendas. While Karabaglar residents have unified around active bottom-up resistance from the beginning to challenge the project-based plans the central government imposed, Fikirtepe residents pursued individual-level negotiations with developers to maximize private returns following the zoning incentives the public authority gave. Despite the socio-spatial similarities between these designated urban renewal project sites, variances in residents' collective waiting strategies have led to different urban politics around project-based urban change.Article Citation - WoS: 17Citation - Scopus: 24A Gis-Based Fahp and Fedas Analysis Framework for Suitable Site Selection of a Hybrid Offshore Wind and Solar Power Plant(Elsevier B.V., 2023) Karipoğlu, Fatih; Ozturk, S.; Efe, B.This study presents a Geographic Information System (GIS) based suitable site selection methodology for a hybrid system that includes offshore wind and solar PV. The methodology utilizes open source databases about decision criteria and applies this data using GIS to determine suitable sites for offshore wind and solar PV systems. For the assessment of multi-criteria which affect the potential hybrid energy power plants and the determination of the best suitable areas, Fuzzy Analytical Hierarchy Process (FAHP) and Fuzzy Evaluation based on Distance Average Solution (FEDAS) are used in the study. Results show that technical criteria has the priority weight of 0.60 while the weight of social criteria is about 0.07. Among sub-criteria, the wind speed has the highest priority weight while distance to port and visibility are the highest criteria of priority weight under economic and social main criteria, respectively. Among the alternatives, Area 2 (A-2) is determined as the best alternative for hybrid offshore power plants in the study area. This proposed methodology can be utilized by decision-makers to determine the best suitable locations for hybrid offshore wind and solar PV systems at any location. This paper suggests a new approach integrating GIS, fuzzy setbased AHP and EDAS as a novelty. © 2023 International Energy InitiativeArticle Citation - Scopus: 1Revisiting the Turkish-Israeli Alliance of the 1990s(Routledge, 2023) Elhan, N.; Şirin, B.The Turkish-Israeli ‘honeymoon’ of the 1990s has been explained by different concepts such as alliance, strategic partnership, or cooperation and friendship, with these concepts often used interchangeably. As a corollary of the Turkish official narrative, which is based on a national security approach, certain explanations were offered in justification of the close relationship, including shared traditional democratic culture and secular character, as well as conducive international atmosphere. According to this construction, Turkey had no option but to align with Israel. On the other hand, while the ‘honeymoon’ was often seen as a foreign policy issue directly affected by the military bureaucracy, negative discourses against Israel in domestic politics, and institutional challenges in the Turkish state structure were often ignored. By way of filling this lacuna, the present article evaluates the impact of domestic factors, including the capital-owning class, lobbies, and institutional changes in the Turkish security apparatus on Turkish-Israeli relations. © 2023 Informa UK Limited, trading as Taylor & Francis Group.Article Mitotyping of Random Bred Cats and Pure Breed Cats (turkish Angora and Turkish Van) Using Non-Repetitive Mitochondrial Dna Control Region(Elsevier, 2024) Bilgen, Nuket; Guvendi, Mervenur; Sezgin, Efe; Can, Huseyin; Koseoglu, Ahmet Efe; Alak, Sedef Erkunt; Un, CemalThe Fertile Crescent appears to be the most plausible region where the domestication of cats commenced through a mutually beneficial relationship between wild cats and early agrarian societies. These domesticated cats then journeyed across the globe mirroring the paths of human migration. An examination of mitochondrial DNA (mtDNA) control region-based mitotyping suggested that a significant majority, exceeding 80%, of globally sampled random-bred and pure-bred cats could be categorized into 12 predominant mitotypes. However, the extent of mitotype diversity within random-bred cats from regions proximate to the Fertile Crescent remains inadequately explored. In light of this we aimed to investigate the mitotype diversity in random bred cats sampled from various regions across Turkey. Additionally, we sought to establish a comparison with the mito-type profiles of locally recognized pure breeds, namely the Turkish Angora and Turkish Van. To unravel their evolutionary narratives, we engaged in comprehensive population genetics analyses at both the individual and mitotype-based levels. Our study encompassed a sample size of 240 specimens, forming the basis for both mitotyping and population genetics scrutiny. Our analysis yielded the identification of nine 'universal' mitotypes (A-J), alongside an 'outlier' mitotype group I. Notably mitotypes A and D emerged as particularly prevalent in contrast to the lesser occurrence mitotypes C, G, and H. With the realm of random bred cats the structure of haplotypes exhibited remarkable diversity presenting distinctions from Turkish Angora and Van breeds. Nucleotide diversity was higher compared to previous reports from Turkey and was one of the highest among reported world cat population estimates. Intriguingly, our investigations did not unveil any pronounced instances of strong selection, population expansions or contractions within any specific population or mitotype. To conclude, our study represents a pioneering effort in uncovering the mitotype profiles and haplotype structures inherent to both random-bred and pure breed cats in Turkey. This endeavor not only broadens our understanding of the feline genetic landscape within the region but also lays the foundation for future inquiries into the evolutionary trajectories and genetic legacies of these feline populations.Article Citation - Scopus: 6Revealing the Climate-Responsive Strategies of Traditional Houses of Urla, İzmir(Sustainable Building Research Center, 2023) Avcı, A.B.; Beyhan, Ş.G.Vernacular houses possess significant climate-responsive properties due to the accumulated information from the trial-and-error method. Therefore, the traditional houses of a region can guide new buildings in terms of adaptation to the climate. The study focuses on the climate-responsive properties of vernacular houses of Urla, İzmir. The study aims to reveal the specific strategies of the traditional houses of Urla in response to the hot and humid Aegean climate. Relating to this purpose, Postane Street, which is among the significant historic streets of the town, is selected as the case area to evaluate the vernacular houses of Urla. The research method is based on the climate-responsive strategies determined from the literature review in the first part. These criteria include “orientation to the sun and wind, the effect of direct sunlight and shading strategy, building envelope and form, interior space organization, integration of greenery, building materials, and roof strategy”. Climate Consultant and Design Builder Software were used to prepare the psychrometric graph and shading regime visualizations. The study showed that the climate-responsive strategies of the street’s vernacular houses are shaped to avoid excessive heat gain in the climate of Urla. The research results are expected to guide sustainable design applications in the same area. © International Journal of Sustainable Building Technology and Urban Development.
