    Ankara : The Department of International Relations of İhsan Doğramacı Bilkent University, 2010.Thesis (Master's) -- Bilkent University, 2010.Includes bibliographical references leaves 104-110.After almost a decade since the September 11 Attacks, in which its sanctuary in Afghanistan has been shattered and the vigilance against it has been strengthened, alQaeda still survives and poses a threat to both Middle Eastern and international security. This research attempts to explain the survival of al-Qaeda after 2001 with regard to its strategy. Therefore, the focus of the research is on the effects of alQaeda’s strategy on its survival. Keeping in mind the conventional approach that handles al-Qaeda as a religious terrorist group, this research attempts to have a broader outlook on al-Qaeda by dealing with it as a non-state armed group. In this way, this research handles the situation as an asymmetrical conflict between alQaeda and the U.S. and its allies. Within the asymmetrical conflict, the strategy that al-Qaeda has pursued involves an indirect approach that compensated for the disadvantages it faced. The results of the research could pave the way for further research on the course of al-Qaeda in the context of the changing security environment in the Middle East.Doğan, SercanM.S

    Aim: The purpose of this investigation was to present our institutional experience of 34 pediatric both bone forearm fractures treated with titanium elastic intramedullary nails. Methods: Thirty-four patients, who were treated with titanium elastic nail for both bone forearm fractures diagnosis between 2011 and 2016, were included in the study. Clinical and radiological evaluation of the patients was retrospectively analyzed. Results: Bone healing process was completed for all patients at a mean of 6.6 weeks. The implants were removed at a mean time of 9.7 months from the index operation. Complications, including skin infections at the entry side of the nail, were recorded in three (8.82%) patients. These three patients had type 1 open fracture according to the Gustilo-Anderson classification and were treated with first generation cephalosporins. In a subjective measure of outcome during follow-up, it was observed that 33 patients (97.06%) were very satisfied and one (2.94%) was satisfied; no patient reported being not satisfied. Conclusion: Since titanium elastic nailing is a safe and effective method of treatment with advantages of easy implantation and removal as well as excellent cosmetic and functional results, elastic stable intramedullary nailing is the first treatment option that should be considered in pediatric both bone forearm fractures

    Nineteen tosylated acyl hydrazone derivatives were synthesized, and their inhibitory activities against monoamine oxidases (MAOs), acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and β-secretase (BACE-1) were evaluated. Compound 3o was the most potent inhibitor of MAO-A, with an IC50 value of 1.54 µM, followed by 3a (IC50 = 3.35 µM). A structural comparison with 3a indicated that the 3-F group in 3o increased its inhibitory activity against MAO-A. Compound 3s was the most potent inhibitor of MAO-B, with an IC50 value of 3.64 µM, followed by 3t (IC50 = 5.69 µM). The MAO-B inhibitory activity increased in the order of 3- > 4- > 2-NO2 groups in 3s, 3t, and 3r, respectively. All the compounds weakly inhibited AChE and BChE, which retained >50% residual activity at 10 µM, except for 3a, which inhibited BChE with an IC50 value of 16.1 µM. Interestingly, 3e, 3f, and 3n inhibited BACE-1 with IC50 values of 8.63, 9.92, and 8.47 µM, respectively, which were lower than the IC50 of the quercetin reference. Compounds 3o and 3s were found to be reversible competitive inhibitors of MAO-A and MAO-B, respectively, with Ki values of 0.35 ± 0.074 and 1.97 ± 0.65 µM, respectively. Moreover, compounds 3e, 3f, and 3n were effective BACE-1 inhibitors. The lead molecules were further investigated by molecular docking studies to elucidate the binding interactions with the target enzymes

    In this study, melliferous plants that the honey bee (Apis mellifera L.) can benefit from among the taxa planted in Düzce University Ornamental and Medicinal Plants Botanical Garden, are presented. Among the 451 taxa planted in the botanical garden, those with these characteristics were determined by reviewing studies on the subject. Of the 165 taxa (36.58%) included in the honey plant class; 119 contain both nectar and pollen, 25 contain pollen, 13 contain nectar, 4 contain both pollen and insect secretion (IS) or sweet sap (SS), 2 contain pollen, nectar and IS or SS, 1 contain both nectar and SS, 1 contain only IS. In order to prevent the decrease in pollinator and pollinator insects, whose numbers are decreasing due to global climate change, a "Bee and Insect Hotel" was placed in the botanical garden. For this reason, the majority of the plants selected for planting were chosen from taxa with honey plant properties. The main purpose here is both to pollinate the plants in the botanical garden and to show and explain the effects of insect species on pollination through nature education

    Marka aşkı; tüketicilerin marka için hissettikleri bağlılığın derecesidir. Bu tez çalışmasında, marka aşkı ile marka sadakati arasındaki ilişki destinasyon pazarlaması kapsamında uygulamalı olarak incelenmiştir. Çalışmada öncelikle; destinasyon, destinasyon pazarlaması, marka aşkı ve marka sadakati konuları teorik olarak ele alınmıştır. Daha sonra literatür taraması kapsamında marka aşkı ve destinasyon marka sadakati değişkenleri ile ilgili çalışmalara ve ölçeklere yer verilmiştir. Tezin uygulama kısmında ise, farklı ülkelerden 302 katılımcı turiste İstanbul destinasyonu ile ilgili sorular içeren bir anket uygulanmıştır. Ankete katılan turistlerin İstanbul destinasyonuna yönelik marka aşkı ve marka sadakati algılamaları incelenerek, bu değişkenlerin demografik özelliklerine göre farklılaşıp farklılaşmadığı da analiz edilmiştir. Yapılan analizler neticesinde; cinsiyet ve medeni durum değişkenlerinin marka aşkı ve marka sadakati üzerinde anlamlı bir etkisi tespit edilmemiştir. Yaşa göre ise, marka aşkında anlamlı bir farklılık bulunurken, marka sadakatinde anlamlı bir farlılık bulunmamaktadır. Gelirin marka sadakatini etkilediği ama marka aşkını etkilemediği saptanmaktadır. Ayrıca, marka aşkı ile marka sadakati arasında yüksek bir ilişki olduğu da tespit edilmiştir.abstractBrand love, degree of a consumer loyalty. Consumer is loyal on pasionate way. In this thesis, it is being examined in the context of practical relationship between brand love and brand loyalty within the destination marketing.

    Introduction: The extension block pinning technique (EBPT) is a popular surgical treatment for mallet fractures; however, it has several drawbacks. The purpose of this randomized clinical trial was to compare EBPT to the pin orthosis-extension block pinning method (PO-EBPT) in the treatment of mallet fractures involving more than one-third of the joint surface but without primary joint dislocation. Materials and methods: Sixty-five patients with mallet fractures were randomized into two groups between June 2017 and January 2020: Group I (33 patients) was treated with EBPT and group II (32 patients) was treated with PO-EBPT. Five patients were lost to follow up due to lack of follow-up and death. There were no significant differences in the clinical and demographic characteristics of both groups. Patients were evaluated according to fracture union, extension lag, distal interphalangeal (DIP) joint range of motion, Crawford’s criteria, and complication rates. The patients were followed-up post-operatively at 2 weeks, 6 weeks, 3 months, 6 months, 1 year, and annually thereafter. Results: A total of 60 patients were randomized into two groups: one (30 patients) was treated with EBPT and the second (30 patients) with PO-EBPT. There were no significant differences between the two groups in terms of fracture union and active DIP joint flexion (P = 0.743 and P = 0.059, respectively). The mean extension lag of the DIP joint in the EBPT group was significantly greater than the PO-EBPT group (10° ± 9.47° vs. 4.17° ± 7.2°, P = 0.009). According to the Crawford criteria, the PO-EBPT group showed significantly better outcomes (P = 0.005). The complication rates were similar between groups (P = 0.45). Conclusion: In comparison to the EBPT technique, the group of patients operated with PO-EBPT had superior clinical outcomes and less loss of extension at the DIP joint according to the Crawford’s criteria
