1-(2-Hydroxyethyl)-2-imidazolidinone as corrosion inhibitor of mild steel in 0.5 M HCl solution: thermodynamic, electrochemical and theoretical studies
(Journal of Adhesion Science and Technology, 2019) Keleşoğlu, Ayşen; Yıldız, Reşit; Dehri, İlyas; Yıldız, Reşit
The inhibition effect of 1-(2-Hydroxyethyl)-2-imidazolidinone (2-HEI) on mild steel (MS) corrosion in 0.5M HCl solution was investigated at different inhibitor concentration and temperature by electrochemical experiments, such as linear polarization resistance (LPR), electrochemical impedance spectroscopy (EIS), potentiodynamic polarization and quantum chemical calculations. The inhibitor adsorption process on mild steel in 0.5M HCl system was studied at different temperatures (20 C–50 C). Furthermore, the surface morphology of MS was also investigated with SEM in the absence and the presence of inhibitor. The adsorption of 1-(2-Hydroxyethyl)-2-imidazolidinone on MS surface is an exothermic process and this process obeys the Langmuir adsorption isotherm. The Quantum chemical findings are good agreed with the empirical data.

Ability, Examination and Inclusive Education: Stretching the Hard Lines of the Educational System
(2016) Sakız, Halis
The aim of this paper is to delve into the debate about the epistemological nature of ability and examination, which we have been continuously exposed to, but rarely scrutinized. In the paper, I refer to Turkey as a case and argue that the dominance of ability-based paradigm and its associated assessment and placement systems have created a new educational order which categorizes schools and students based on how they perform at a single point in time. What is more, I critically evaluate the construction of “abilities” and “disabilities” through the means employed in the education system, followed by a discussion of the examination culture as a product of an ability-based system. Finally, I propose inclusive education as a powerful means of transforming the education system to an equitable and educationally effective one in which all students are welcomed and provided with education of good quality that both enriches childhood and maximizes chances of leading a fulfilled adult life.
Abluted capitalism: Ali Shariati's critique of capitalism in his reading of Islamic Economy
(Sage, 2015) Şengül, Serdar
Islamic sociologist Ali Shariati is a leading figure of the reconstruction of religious thought in the Islamic world known especially for his anti-capitalist stance and leftist reading of Islamic history. In the philosophy of history that he developed, he classified religions as religions of tawheed (unicity of God) and religions of shirk (multiple gods). According to this new reading of history, the main struggle is not between religion and secularism but between religions of tawheed and of sheerk. The issue of the gaining and the distribution of the property is central to his classification. Shariati argued that followers of tawheed and of sheerk can be found in all religions including Islam. To support his argument Shariati explored how capitalistic understanding of Islam has been developed and legalised while anti-capitalist messages and orders of Islam were marginalised and illegalised just after the death of the Prophet Mohammed. He analysed the rivalry between his close companions over the content of a proper Islamic economic order and how this rivalry gave way to two contradicting understanding of Islam, marks of which can be seen today in the contemporary Muslim world. He coined the term abluted capitalism' to define the economic policies of Muslim sovereigns to make Islam compatible with capitalist economic principles.
The actual and the possible: modality and metaphysics in modern philosophy, edited by M. Sinclair, Oxford, Oxford University Press, 2017, 256 pp., £50.00, ISBN 9780198786436
(2018) Yirmibeş, Mert Can
This new collection comprises nine essays offering a wide array of views on modal metaphysics. One of the aims of the collection is to provide a recent survey of modal theories from the seventeenth century to the twentieth century. The book presents ‘analytic’ and ‘continental’ theories in modal metaphysics, with many diversely interpreted subjects, including the subjectivity and objectivity of modalities and the notion of possibility that was a focus of seventeenth- to twentieth-century modal metaphysics. The book provides interpretations of modal theories and responses to more contemporary issues, such as the (ir)reducibility of modal categories. The essays take diverse approaches, with some more exegetical and some engaging critically with the literature. Here I consider four essays within the volume that exemplify these approaches.
Adaptation and Future Expectations of Syrian Refugees Living in Mardin: Comparison Between 2014 and 2021
(2022) Apak, Hıdır
The aim of this study is to reveal the changes to the adaptation process for Syrian refugees over the years and to determine their future expectations. The study represents a quantitative research effort in which the survey model was used. In this study, the integration and future expectations of Syrian refugees were examined comparatively for two samples showing similar characteristics in two different time periods. The research is descriptive in order to understand and make sense of the change in Syrian refugees' adaptation, and their future expectations. The study sample consists of 178 Syrian refugees living in Mardin, Turkey since 2013. It was determined that the majority did not have difficulties adapting to Mardin, Turkey and there has been a negative change in their adaptation status over the years. The main result of the study with regard to future expectations is that the majority of the participants complained about the "uncertainty" they experienced, let alone drawing a positive picture of what kind of future awaits them. It has also been determined that this uncertainty has increased compared to 2014. The present study is valuable in that it reveals various results within a relational analysis model.
Adaptions in subsistence strategy to environment changes across the Younger Dryas-Early Holocene boundary at Kortiktepe, Southeastern Turkey
(Sage Journals, 2022) Sıddıq, Abu Bakar; Benz, Marion; Sıddıq, Abu Bakar; Özkaya, Vecihi
The site of Körtiktepe in southeastern Turkey is one of few sites in the Upper Mesopotamia basin that attests continuous, permanent occupation across the boundary from end of the colder, drier Younger Dryas (YD) into the comparatively wetter and warmer Early Holocene (EH). This allows for the study of the degree of environmental change experienced on a local level over this boundary as well as for the study of the adaptations that the occupants of the site undertook in response to these changes. The mammal assemblage of Körtiktepe remains relatively stable across the YD – EH transition with the main contributors to diet being mouflon (Ovis orientalis) and red deer (Cervus elaphus) in approximately the same quantities, although the contribution of aurochs (Bos primigenius) increases in the EH. The most significant changes can be seen in the shift in avifauna remains, with a sharp increase of waterbirds during the EH. It is proposed that these shifts reflect changes in the local environment with an increase in woodland cover as well as expansion of local waterways, which is generally consistent with previously published archaeobotanical studies. In terms of species exploited, mortality profiles as well as size distribution of mammals, a great deal of continuity is observed. This suggests that over this particular period the local impact of the beginning of the Early Holocene was not overly dramatic, allowing for cultural continuity of previously established subsistence strategies.

Adoption and abandon of camel culture in Southeast Anatolia
(Selçuk Efes Kent Belleği Yayınları, 2018) Sıddıq, Abu Bakar; Erdem, Çağdaş; Şanlı, Süleyman
Camels are exotic animals in Anatolia. Except the Palaeolithic site of Karain Cave, no pre-Bronze Age archaeological site reveals any camel remains so far in Anatolia. However, domestic camel became common and very significant in the Early Imperial as well as in the Roman and Byzantine Anatolia. Southeast Anatolian region, being the corridor between Anatolia and Mesopotamia, always played key roles since the early stage of the spread of camel culture in rest of Anatolia. Moreover, from the Bronze Age to nineteenth century onwards, camel pastoralism was very lucrative in Southeast Anatolia mainly because of trade, transport and warfare. While camel culture was gradually abandoned in rest of the Anatolia in the beginning of twentieth century, camels still remained as an important socio-cultural part of pastoral groups in Southeast Anatolia until last 30 years. In the light of archaeozoologic, ethnohistoric and ethnozoological data, this review is aimed to illustrate a glimpse of camel culture in Southeast Anatolia throughout different cultural periods in the region.
Adsorption and inhibition effect of 2,4-diamino-6-hydroxypyrimidine for mild steel corrosion in HCl medium: experimental and theoretical investigation
(SPRINGER HEIDELBERG, 2019) Yildiz, Resit; Yıldız, Reşit
2,4-Diamino-6-hydroxypyrimidine (2D6H) was examined as corrosion inhibitor of mild steel (MS) in 0.1M HCl using potentiodynamic measurements, linear polarization resistance (LPR), scanning electron microscopy, electrochemical experiments, and quantum chemical calculations. All measurements show that the corrosion inhibition effectiveness is forthright compared to the concentration of 2D6H ranging from 0.5 to 10.0mM. Adsorption of 2D6H on the MS surface in the presence of HCl is determined to obey Langmuir adsorption isotherm. The electronic features elucidated by quantum chemical calculations were associated with the experimental inhibition productivities. The mechanism of inhibition was revealed by E-pzc measurements.

AFLATOXIN M-1 IN TRADITIONAL HOMEMADE YOGHURTS MARKETED IN SOUTHEASTERN TURKEY
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2019) Gürbüz, Semra; Kılıç Altun, Serap
This study was performed to determine the presence and levels of aflatoxin M-1 (AFM(1)) in yoghurt produced by traditional methods in small scale enterprises in Mardin and Sanliurfa provinces located in Southeastern Turkey and to evaluate the yoghurt in terms of food safety. A total of 90 yoghurt samples, 42 from Mardin and 48 from $anhurfa were collected from small-scale retailers and tested for AFM(1) by enzyme-linked immunosorbent assay (ELISA). AFM(1) was detected in 34 (37.8 %) of 90 yoghurt samples at the levels ranging from 10 to 515 ng/kg. Five (11.9 %) samples (ranging from 10 to 515 ng/kg) from Mardin and 29 (60.4 %) samples (ranging from 10 to 101 ng/kg) from Sanliurfa were found to be contaminated with AFM(1). There was a statistically significant difference between the samples collected Mardin and Sanliurfa concerning the presence frequency of AFM(1) (p=0.000). The AFM(1) levels of 16 (17.8 %) positive yoghurt samples were higher than the legal limits. The results of this study have revealed that the traditionally produced homemade yoghurt is contaminated with AFM(1) and poses health risk for consumers.

(Springer Verlag, 2017) Kılıç Altun, S.; Gürbüz, S.; Ayağ, E.
This study was performed to determine aflatoxin M1 (AFM1) in human breast milk samples collected in Şanlıurfa, located in Southeastern region of Turkey, and to investigate a possible correlation between AFM1 occurrence (frequency and levels) and sampling seasons. Human breast milk samples collected in December 2014 and in June 2015 from a total of 74 nursing women, both outpatient and inpatient volunteers in hospitals located in Şanlıurfa, Turkey, were analyzed using competitive enzyme-linked immunosorbent assay (ELISA) for the presence of AFM1. AFM1 was detected in 66 (89.2%) out of 74 samples at an average concentration of 19.0 ± 13.0 ng/l (min.-max., 9.6–80 ng/l). There was a statistically significant difference between December and June concerning AFM1 levels (p < 0.05). Further detailed studies will be needed to determine the main sources of aflatoxins in food, to establish protection strategies against maternal and infant exposure to these mycotoxins. © 2016, Society for Mycotoxin Research and Springer-Verlag Berlin Heidelberg.

Aging and cardiac implantable electronic device complications: is the procedure safe in older patients?
(ELSEVIER, 2023) Günlü, Serhat; Aktan, Adem; Kılıç, Raif; Günlü, Serhat; Arslan, Bayram; Arpa, Abdulkadir; Güzel, Hamdullah; Tatlı, İsmail; Aydın, Saadet; Suzan, Veysel; Demir, Muhammed
Background In this study, we investigated whether there is a higher incidence of cardiac implantable electronic devices (CIED) procedures related complications in older (≥75 years) than in younger (<75 years) patients. Methods This retrospective cohort study enrolled patients who had undergone CIED procedures (de novo implantation, system upgrade, generator substitution, pocket revision or lead replacement) at two heart centers in Turkey between January 2011 and May 2023. The primary composite endpoint included clinically signifcant hematoma (CSH), pericardial efusion or tamponade, pneumothorax, and infection related to the device system. Secondary outcomes included each component of the composite end point. Results The overall sample included 1923 patients (1419<75 years and 504 aged≥75 years). There was no diference between the groups in terms of cumulative events defned as primary outcome (3.5% vs. 4.4%, p=0.393). Infection related to device system was signifcantly higher in the≥75 age group (1.8% vs. 3.4%, p=0.034). There was no signifcant diference between the groups in terms of clinically signifcant hematoma and pneumothorax (0.7% vs. 0.4%, p=0.451, 1.4% vs. 1.0%, p=0.477, respectively). In multivariate model analysis, no association was found between age≥75 years and infection related to the device system. Conclusion Infection rates were relatively higher in the patient group aged≥75 years. This patient group should be evaluated more carefully in terms of infection development before and after the procedure.

Ahmed Anzavur: Soldier, Governor, and Rebel. a Reevaluation of a Late Ottoman Military Man
(Oriental inst Czech Acad Sci, 2023) Yelbasi, Caner
Following the Russian conquest of the North Caucasus, many Muslims from the region were exiled to the Ottoman Empire from the 1860s onwards. They were settled in different parts of the empire from the Balkans to Anatolia to the Syria and Iraq vilayets. By following this policy, the Ottoman state ensured that many Circassians would become part of the Ottoman army, ruling elites, harems and agricultural workforce. Anzavur Ahmed's family was one of them. Although he did not graduate from military school, he participated in the army during the war in Libya (1911), the Balkan Wars (1912-1913), and the First World War (1914-1918). He was also appointed as the governor of Izmit (1920). Anzavur Ahmet is portrayed as a rebel by Turkish official historiography, but in reality, he was much more than that. He was an Ottoman Governor, and supported by Ottoman administrators such as Damad Ferid and Ali Kemal, who were against the Kuvayi Milliye because they believed that the empire would eventually emerge from the chaotic atmosphere of the post-First World War period and make an agreement with the British. This article argues that although Ahmed Anzavur has been labeled a rebel and a traitor according to the official historiography, it is difficult to use these labels given the circumstances of his time.
Ali Shariati
(Palgrave Macmillan, Cham, 2023) Ateş, Enes
This entry examines Ali Shariati’s ideas, which provide a modern interpretation of emancipatory and revolutionary Islam in the context of Shia thought. Shariati merged political, social, and intellectual activism. He not only addressed internal divisions within Shiite Islam but also established a socially just and left-leaning model for Muslims worldwide to advocate for an Islamic alternative to Western methods of thinking. Leaving aside the validity of ambiguous labels such as “Islamic Marxism” or “socialist Islam,” Shariati’s Islamic interpretation is rooted in a socialist philosophical and ethical framework. He drew upon Islamic history and the Islamic canon, modifying his interpretation of pretext (tradition, history, and institutional structures) and text (canon) to create a revolutionary con-text, a revolutionary interpretation of Islam. His criticism of capitalism, as a manifestation of his economic understanding, combined with his interpretation of religion on both concrete and abstract levels and took on an activist character. Shariati’s economic and philosophical defense of a populist and social justice line fills his unique value in the history of thought. In addition to the specific conditions of Iran, these aspects demonstrate the intellectual adventure of the world’s Muslims.
