Buildings Damages After Elazig, Turkey Earthquake on January 24, 2020
(SPRINGER, 2021) Doğan, Gamze; Ecemiş, Ali Serdar; Korkmaz, Serra Zerrin; Arslan, Musa Hakan; Korkmaz, Hasan Hüsnü
A 6.8-magnitude earthquake that occurred on January 24, 2020, has been effective in Turkey's eastern regions. The earthquake, with recorded peak ground acceleration (PGA) value of 0.292 g, caused the destruction or heavy damage of buildings, especially in the city center of Elazig province. The purpose of this paper was to share the results of detailed investigation in the earthquake-stricken area. Additionally, the causes of damages and failures observed in the buildings were compared to those that had occurred in previous earthquakes in Turkey. In this study, the damages observed in especially RC buildings as well as in masonry and rural buildings were summarized, the lessons learned were evaluated, and the results were interpreted with reference to Turkish earthquake codes. In the study, it was particularly emphasized why the building stock underwent such damage even though the buildings were exposed to earthquake acceleration well below the design acceleration values.

Outdoor Thermal Comfort Conditions During Summer in a Cold Semi-Arid Climate. a Transversal Field Survey in Central Anatolia (turkey)
(PERGAMON-ELSEVIER SCIENCE LTD, 2019) Canan, Fatih; Golasi, Iacopo; Ciancio, Virgilio; Coppi, Massimo; Salata, Ferdinando
In the present study the outdoor thermal comfort conditions in Konya (Central Anatolia, Turkey) were examined during summer. This is why a transversal field survey was carried out and over 300 questionnaires were filled by randomly chosen participants. Moreover, environmental variables as air temperature, wind speed, relative humidity and globe temperature were constantly measured. This allowed to relate the thermal perception and preference votes given by the interviewees to the morphological and furniture characteristics of the surveyed sites. Then, taking into account at the same time all the obtained data, a regression line between the thermal perception votes and the corresponding PET (Physiological Equivalent Temperature) values was obtained and a neutral PET value of 26.8 degrees C was calculated. Based on a logistic curve model with the probit function, a preferred PET value of 19.2 degrees C was determined. On the other hand, the PET comfort range of (21.6)-(32.0) degrees C was obtained by considering, as thermal comfort interval, the range (- 0.5)-(+ 0.5) of the ASHRAE 7-point scale. Finally, two outdoor thermal comfort indexes were introduced. The first one, called Turkish Outdoor Comfort Index (FOCI), is able to predict the thermal perception of the considered population in hot conditions. In the second case, the Predicted Percentage of Dissatisfied (PPD) relation was modified based on the surveyed data and outdoor sites.

Outdoor Thermal Perception and Comfort Conditions in the Koppen-Geiger Climate Category Bsk. One-Year Field Survey and Measurement Campaign in Konya, Turkey
(ELSEVIER, 2020) Canan, Fatih; Golasi, Iacopo; Falasca, Serena; Salata, Ferdinando
This study presents an analysis of the thermo-hygrometric conditions in the city of Konya (Turkey). A one-year transversal field surveywas carried out in the Selcuk University campus and 2295 valid questionnaireswere collected. In each questionnaire, randomly selected interviewees provided personal information and judged their perception and thermal preference according to the ASHRAE 7-point and McIntyre scales, respectively. For each interviewee, a value of the Physiological Equivalent Temperature (PET) was calculated based on the values of operational variables obtained from the questionnaires and the environmental variablesmeasured during the survey. This allowed to calculate the seasonal preferred and neutral PETs and the annual PET comfort range. Also, the scale of the PET thermal perception was determined for the Konya population and, more generally, for the inhabitants of the BSk Koppen-Geiger climate zone. Statistical analyzes carried out in terms of Variance Inflationary Factor, multicollinearity assessment and Best Subsets Analysis led to the identification of the Turkish Outdoor Comfort Index, an empirical index able to predict the average value of the thermal perception of a large group of individuals living in the aforementioned climate zone. Moreover, the equations of the Predicted Percentage of Dissatisfied (PPD) were obtained for each season. (c) 2020 Elsevier B.V. All rights reserved.

Processing of Anode Slime With Deep Eutectic Solvents as a Green Leachant
(ELSEVIER, 2021) Topçu, Mehmet Ali; Kalem, Volkan; Rüşen, Aydın
This paper describes an efficient process of recovering valuable metals from a copper anode slime sample using green chemicals such as choline chloride (ChCl) based deep eutectic solvents (DESs). The leaching agents include ChCl-urea, ChCl-ethylene glycol, ChCl-urea-ethylene glycol and ChCl/urea-deionized water in a 1:2, 1:2, 1:0.5:1.5, and 1:1 ratio, respectively. Prior to leaching experiments, chemical and mineralogical characterization of copper anode slime was performed. Considerable amount of precious metals was detected in the copper anode slime by chemical analysis. The main phases of copper anode slime detected by XRD and SEM/EDX analysis were namely Cu2O, SnO2, and, PbSO4. After leaching experiments, 97% of copper was recovered from the copper anode slime using ChCl-urea under an optimum condition at 95 degrees C of reaction temperature, 4 h reaction duration and, 1/25 g/mL solid/liquid ratio. The results showed that 91% of silver was extracted from the anode slime under the optimum condition with ChCl-urea DES composition, 95 degrees C reaction temperature, 48 h reaction duration, and 1/10 solid/liquid ratio. Gold was not leachable in the experiment using ChCl based DES with hydrogen bonding reagents such as urea and ethylene glycol. Moreover, the results revealed that PbSO4 was very soluble in DES prepared by ChCl and urea.

Sustainability of Urban Regeneration in Turkey: Assessing the Performance of the North Ankara Urban Regeneration Project
(PERGAMON-ELSEVIER SCIENCE LTD, 2020) Korkmaz, Cansu; Balaban, Osman
The increasing environmental footprints of cities necessitated the integration sustainability principles into urban planning and development frameworks. The growing attention on urban sustainability also influenced the policy and the practice of urban regeneration. The quest for new methods for regenerating existing urban quarters in sustainable manners resulted in the concept of sustainable urban regeneration. The concept aims to develop urban regeneration projects in line with the three key pillars of sustainable development. Since the turn of the new millennium, urban regeneration initiatives in Turkish cities have gained a new momentum, mainly due to the increasing interest by public and private sectors. As expected, squatters constituted one of the main focuses of the recent initiatives for urban regeneration. Nevertheless, the Turkish experience of urban regeneration differs from the international experiences in terms of the motivation behind and the scope of the projects. Despite the growing link between sustainability and urban regeneration in international practices, sustainability has not yet been a major motivation for urban regeneration practices in Turkey. This research assesses the sustainability performance of one of the most prominent examples of squatter regeneration in Turkey, namely the North Ankara Urban Regeneration Project (NAURP). The project has been evaluated by means of an indicator-based methodology. The research indicates that the project's contribution to urban sustainability has been minimal and thus, further efforts are required to improve the sustainability performance of urban regeneration projects in Turkey. In the light of this finding, policy implications have been made to push sustainable urban regeneration agenda in Turkey.
