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 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 - WoS: 2Citation - Scopus: 1A Review of the Geothermal System Evolution and Distribution in the Central Anatolian Crystalline Complex (türkiye)(TUBITAK, 2023) Şener, M.F.; Öztürk, M.Z.; Baba, A.Türkiye is located in the Mediterranean sector of the Alpine–Himalayan tectonic belt and is among the foremost seven countries in the world having an abundance of geothermal resources. The Central Anatolian Crystalline Complex (CACC) is one of the most important geothermal regions in Türkiye. This study aims to evaluate the geothermal system of CACC using the geological, structural, and hydrogeochemical properties that were obtained from previous studies. The present study investigated and evaluated the hydrogeochemical and isotopic properties of 762 water samples belonging to 45 different localities from 41 scientific studies. The result shows that CACC has different heat sources and different hydrogeochemical processes. Major element chemistry of the water reveals that the geothermal fluids are mostly of the Ca-Mg-HCO3, Na-Cl-HCO3, and Ca-Cl water types. Silica geothermometers suggest that the reservoir temperature ranges from 48 to 180 °C. Based on the δ18O-δD relationship, water samples have a high-altitude meteoric origin. Stable isotopic data indicate that the geothermal fluids are formed by local recharge and deep circulation of meteoric waters. © TÜBİTAK.Conference Object Heat Load Factor for Geothermal District Heating System Design(National Technical University of Athens, 2006) Yıldırım, Nurdan; Gökçen, GüldenDesign of heating systems using conventional fuels is based on peak load which is calculated according to the coldest outdoor design temperature. But in geothermal district heating system design it is common practice to use a heat load factor between 0.6-0.7 since the resource is continues, cheap and system can be run for 24 hours a day. Heat load factor can be defined as a ratio of actual heat load to design heat load of the system. In this study, a geothermal district heating system is designed for Izmir Institute of Technology Campus, Izmir, Turkey and simulated for a heat load factor range of 0.5-1. For the Campus case, the heat load factor is determined as 0.53-0.0.67 based on indoor air temperature and operational cost.Article Citation - WoS: 1Citation - Scopus: 1The Current Status of Thrips Parasitoids Ceranisus (hymenoptera: Eulophidae) Species in Turkey Based on Morphology and 28s D2 Rdna(Türkiye Entomoloji Derneği, 2010) Doğanlar, Oğuzhan; Doğanlar, Mikdat; Frary, AnneThe aim of this study was to investigate genetic analysis of the species within genus Ceranisus (Hymenoptera: Eulophidae) that are interesting groups found in South Eastern Anatolia and Eastern parts of Mediterranean Region of Turkey and to compare with the other thrips-parasitoids between May 2006 and May 2007. Totally, 143 specimens (30 male: 113 female) belonging to Ceranisus genus were collected from 20 locations of 38 different localities in Hatay, Gaziantep, Adiyaman and Sanliurfa provinces. The population was divided into 13 groups based on morphologic characters. Phylogenetic relationships amongst Ceranisus species (Chalcidoidea: Eulophidae) were gathered from DNA sequence data. Fifteen species of thrips chalcid parasitoids were analyzed using one gene, D2 domain of the 28S ribosomal DNA. Among morphologically distinct 13 species/taxonomic groups, 3 of them identified as new species according to the genetical analysis. Four of the other species occurred in C. nr. lepidotus group while 5 of C. nr. bozovaensis consisted of two groups. To conclude 3 new species of Ceranisus and 3 different groups that may yield new species were determined in Turkish Ceranisus population.Article Helminth Parasites of European Glass Lizard, Pseudopus apodus (Pallas, 1775) (Squamata: Anguidae), Collected from Northern Turkey(Pleiades Publishing, 2025) Tok, Cemal Varol; Hayretdaǧ, Sibel; Dinçaslan, Yunus Emre; Düşen, Serdar
