Energetska varnost v času krize: študiji primera Bolgarije in Srbije
No full textThis thesis aims to assess the EU’s external energy policy and to what degree it has been embraced by small states during the energy crisis by posing the question, “How does European Union membership influence the external energy policy decisions of small states within the foreign policy dimension during energy security crises?”. To answer this, the research is taking Bulgaria and Serbia as case studies due to their similar population sizes, GDP, and energy consumptions. This research conceptualizes energy security and energy diplomacy to understand how diplomacy and energy dependencies are interrelated and how this relationship can be utilised as a tool in international relations. Through supporting the qualitative work on foreign policy analysis with the quantitative analysis of the energy industry structures and energy dependencies of Serbia and Bulgaria in a comparative manner, this research is conducting mixed research on the issue. The comparison of Bulgaria and Serbia enables the author to analyse and understand the role of EU membership
Assessment of mitogen-activated protein kinases as therapeutic targets for the treatment of babesiosis and theileriosis
No full textThe Piroplasmida order comprises parasitic protozoa including the Theileria and Babesia species that are transmitted by vector ticks and can cause severe diseases in domestic and wild animals. Because of limited therapies and available drug resistance, the discovery of new, effective, and safer drugs for veterinary use is important. Mitogen-activated protein kinases (MAPK) are a group of serine-threonine protein kinases found in diverse species, including animals and protozoa that conduct vital cellular functions. Therefore, they have been at the centre of drug design studies for many years. Computer-aided structure-based drug design is a fast and effective way in drug discovery efforts to identify candidate compounds. In this study, we conducted comparative sequence analysis of MAPK proteins from the Theileria (T. annulata, T. parva., T. orientalis, and T. equi) and Babesia species (B. bigemina, B. microti, and B. bovis). Three-dimensional protein structures from relevant species (T. annulata and B. bovis) were modelled and compounds were screened for interaction. Results showed that the inhibitors designed for human use could also be potent against Prioplasmida MAPKs. Furthermore, the structural differences between Prioplasmida and mammalian MAPKs could be a way for researchers to better instigate selective drug design
Recent and future innovations in the treatment of heart failure [Kalp yetersizliǧi tedavisinde yeni açılımlar: Şimdi ve gelecek]
No full textHeart failure is still an important public health problem despite important advances regarding its treatment. Several new treatment strategies are being investigated in order to contend with this disease. Strategies proved to be safe and effective in clinical trials are being adapted to clinical practice. In this review, we will first focus on most recent treatment strategies that are recommended to be used in clinical practice and then try to mention novel strategies which are still being explored in preclinical studies. © 2013 by AVES Yayincilik Ltd
Improving the surface quality of TI6al4v parts produced by Additive manufacturing with magneto electro polishing
No full textEklemeli İmalat teknolojisi, prototip üretiminin yanında düşük adetli fonksiyonel parçaların üretilebilmesi için en uygun yöntem olarak kabul edilmektedir. Eklemeli imalat ile geleneksel yöntemlerle üretilmesi mümkün olmayan veya karmaşık iç unsurları olan parçalar yapılabilmektedir. Polimer, seramik veya metal gibi çok değişken materyallerin kullanılabilmesi bu teknolojiye olan ilgiyi daha da artırmıştır. Bu çalışmada Eklemeli İmalat ile Ti6Al4V metal alaşımı kullanılarak üretilen deney parçalarının yüzey kalitesinin iyileştirilmesi hedeflenmiştir. Bu araştırmada uygulanan yöntem olan Elektro-Parlatma, anot katot ve elektrolit kullanımını içeren elektrokimyasal yüzey aşındırma işlemidir. Manyetik etki altında yapılan Elektroparlatma işlemi ise Magneto-Elektroparlatma (MEP) olarak tanımlanmıştır. Bu çalışmada mevcut araştırmalara katkı sağlamak için EP ve MEP deney düzenekleri hazırlanmış ve Ti6Al4V alaşımı ile üretilen parçalara bu işlemler uygulanmıştır. Standart EP ile MEP karşılaştırılarak MEP işleminin standart EP ye göre daha iyi sonuç verdiği yapılan ölçümlerle belirlenmiştir. Karmaşık geometriye sahip parçalara uygulanan MEP işleminin diğer fiziksel ve kimyasal yöntemlere kıyasla daha düzgün yüzey formu oluşturduğu gözlenmiştir.Additive Manufacturing technology is considered the most suitable method for producing lowvolume functional parts as well as prototype production. With additive manufacturing, parts
that cannot be produced using traditional methods or parts with complex internal elements can
be made. The ability to use very variable materials such as polymer, ceramic or metal has further
increased the interest in this technology. In this study, it was aimed to improve the surface
quality of test pieces produced using Ti6Al4V metal alloy with Additive Manufacturing.
Electropolishing, the method applied in this research, is an electrochemical surface etching
process that involves the use of anode, cathode and electrolyte. The electropolishing process
performed under magnetic influence is defined as Magneto-Electropolishing (MEP). In this
study, in order to contribute to existing research, EP and MEP experimental setups were
prepared and these processes were applied to parts produced with Ti6Al4V alloy. By comparing
standard EP with MEP, measurements have shown that the MEP process gives better results
than standard EP. It has been observed that the MEP process applied to parts with complex
geometry creates a smoother surface form compared to other physical and chemical methods
Review of Liquefaction Around Marine Structures by B. Mutlu Sumer
No full textOwing to the growth of activities in the marine environment, the phenomenon of fluid–soil structures around marine infrastructures has attracted great attention among coastal and geotechnical engineers. Seabed liquefaction is one of the key failure mechanisms around marine installations such as breakwaters, pipelines, platforms, and offshore wind turbine foundations. Therefore, evaluation of the seabed instability around marine structures is particularly important for engineers involved in the design of foundations of marine infrastructures.No Full Tex

MUTLU B.: Modeling and evaluating narrative gestures for humanlike robots
No full textAbstract—Gestures support and enrich speech across various forms of communication. Effective use of gestures by speakers improves not only the listeners ’ comprehension of the spoken material but also their perceptions of the speaker. How might robots use gestures to improve human-robot interaction? What gestures are most effective in achieving such improvements? This paper seeks answers to these questions by presenting a model of human gestures and a system-level evaluation of how robots might selectively use different types of gestures to improve interaction outcomes, such as user task performance and perceptions of the robot, in a narrative performance scenario. The results show that robot deictic gestures consistently predict users ’ information recall, that all types of gestures affect user perceptions of the robot’s performance as a narrator, and that males and females show significant differences in their responses to robot gestures. These results have strong implications for designing effective robot gestures that improve human-robot interaction. I
