Olga Lebedeva ( Madame Gülnar): A Russian Orientalist and Translator Enchants the Ottomans

Based on the studying of a number of archive and scientific literature sources, the article attempts a research of life and works of the first Russian female orientalist Olga Sergeevna Lebedeva. Under the pseudonym ‘Gülnar’, she was one of the first to introduce the Turkish reading public to the treasures of Russian literature, thus making an invaluable contribution to Turkish–Russian literary connections at the end of the nineteenth century. A special place in the article is devoted to Olga Lebedeva’s translations and literary critical studies in the Ottoman Empire in 1890s and also interrelationship between her and the prominent Ottoman writer and publisher Ahmet Mithat Efendi

In the Digital Training Camp: Taking traditional diplomacy into the digital age

Social media have permanently changed the area of foreign policy: transparency in political activity, interaction rather than mere information, and communication on an equal footing are but a few of the implications for a reconfiguration of international relations. Governmental actors are responding to these changes in the digital world. Thus, states such as the USA, Great Britain and Sweden have already defined communication via social networks as one of the core tasks of their foreign policy. They use cyberspace as a medium for conducting virtual diplomacy - and in this way, they try to bring their foreign policy into line with the changes in media

Biocompatibility and microstructural characterization of PVD coated and nitrogen implanted Co-Cr alloy

Thesis (Master)--Izmir Institute of Technology, Materials Science and Engineering, Izmir, 2004Includes bibliographical references (leaves: 80-83)Text in English; Abstract: Turkish and Englishxiii, 87 leavesIn this study, the effectiveness of nitrogen ion implanted and TiN coated layers on CoCrMo alloy (ISO 5832-12) in preventing metal ion release during in vitro exposure of these layers to simulated body fluid (SBF) was investigated. The experimental results clearly show higher levels of cobalt ion release from nitrogen implanted CoCrMo material surfaces into simulated body fluid as compared to the as-polished CoCrMo alloy. The results clearly indicate that nitrogen ion implantation used for modification of fcc CoCrMo alloy surfaces lead to the development of various near surface microstructures. Nitrogen ion implantation was carried out at 60 and 30 keV ion energies with the corresponding current densities of 0.1 and 0.2 mA/cm2, respectively, for the substrate temperatures of 100, 200 and 400 °C and implantation time of 30 minutes. Near surface crystal structures and phases, nitrogen ion implanted and TiN coated layer thicknesses were characterized by a combination of symmetric (.-2.) and grazing incidence x-ray diffraction (XRD and GIXRD) and cross-sectional scanning electron microscopy (SEM). Metal ion release into the simulated body fluid was analyzed by atomic absorption spectrometry (AAS) and inductively coupled plasma optical emission spectrometry (ICP-OES). The experimental XRD results clearly show the formation of a metastable, fcc, high-N phase (.N) in mainly fcc CoCrMo alloy for the ion beam conditions at 400 °C. The lower implantation temperatures, 100 and 200 °C, for both 60 and 30 keV ion energies, result in a nitride phase, (Co, Cr, Mo)2+xN. The cross sectional SEM results for the specimens implanted at the 60 and 30 keV ion energies at 400 °C reveal quite clearly the uniform nature of the .N layers. The .N layer thicknesses, based on the SEM data, were found to be 450 and 540 nm for the 60 and 30 keV implanted specimens, while the (Co, Cr, Mo)2+xN nitride layer has a thickness range from 150 to 250 nm for the 60 and 30 keV at 100 and 200 °C implantation conditions. The SEM results also indicate that the (Co, Cr, Mo)2+xN nitride and .N phase layers on the CoCrMo alloys have high etch resistance suggesting enhanced corrosion resistance for the N implanted specimens compared to the substrate material. The XRD and SEM results for the TiN coated (via PVD) specimens show that the fcc TiN coatings exhibit (111) preferred orientation and have a coating thickness of . 3 µm with a columnar type of growth mode. The experimental AAS results show that in vitro exposure of the N implanted layers result in higher levels of cobalt ion release into the SBF than the as-polished substrate CoCrMo alloy. This was attributed to the rougher surfaces of the N implanted specimens compared to that of the substrate material (i.e, rougher surface implying a larger area is available for metal ion release). It was also found that the specimens implanted at the lower substrate temperatures of 100 and 200 °C have lower levels of Co ion release compared to those specimens implanted at the substrate temperature of 400 °C. The limited dissolution of cobalt, in this case, was explained by the stronger bonds of metal-N in the nitride phase than those of .N phase. Furthermore, the AAS data indicate higher cobalt ion release rate for the N implanted specimens compared to the substrate alloy and suggest transport (diffusion) controlled dissolution reaction mechanism. The AAS results show no cobalt ions are released from the TiN coated specimens (i.e, the release levels were below the analytical detection limit of the AAS apparatus). This indicates that the TiN coated layer can be an effective barrier for reducing the metal ion release from the substrate alloy. The SEM/EDX study of the surface morphologies of the N implanted, TiN coated and as-polished CoCrMo alloy test specimens after the static immersion test clearly indicate calcium phosphate formation on the as-polished alloy, while there was almost no phosphate precipitates on the surface of N implanted and TiN coated specimens. While the experimental results show higher levels of cobalt ion release for the N implanted specimens compared to the substrate material, the overall release levels are found to be below toxic levels for the human body

Cynicism and organizational cynicism trends of academicians at Suleyman Demirel University Faculty of Economics and Administrative Sciences

Araştırmanın amacı Süleyman Demirel Üniversitesi İktisadi ve İdari Bilimler Fakültesi’nde görev yapan akademisyenlerin genel sinizm ve örgütsel sinizm eğilimlerini tespit etmektir. Bu amaçla genel sinizm eğilimi Wrightman (1992) tarafından, örgütsel sinizm ise Brandes (1997) tarafından geliştirilen ölçekler kullanılarak araştırılmıştır. Alan araştırması sonucunda elde edilen veriler frekans, faktör ve korelasyon analizinlerine tabi tutularak incelenmiş ve sonuçlar yorumlanmıştır.The aim of this study is to determine the cynicism and organizational cynicism trends of academicians at the Faculty of Economics and Administrative Sciences at Suleyman Demirel University. For this purpose, while the cynicism is analysed using the scale developed by Wrightman (1992), for the organizational cynicism, Brandes’s (1997) scale is prefered. The data obtained in this field study is processed and the results are interpreted through the frequency, factor and correlation analyses
