Preparation and Characterization of Self-Assembled Thin Film of MPS-Capped ZnS Quantum Dots for Optical Applications

For this study, we prepared colloidal ZnS quantum dots using 3-mercaptopropyltrimethoxysilane (MPS) as the capping agent. Colloidal ZnS quantum dots were directly deposited on glass substrates by a spin coating process. Therefore, self-assembled films made of ZnS quantum dots in a SiO2 network were obtained using only one production step. The films were heat-treated at 100°, 125°, 150°, 175° and 200°C in an N2 atmosphere. The results showed that the dimension of quantum dots changed from 2.8 nm to 3.2 nm by heat treatment. The refractive index, extinction coefficient, thickness, and dielectric coefficient values of the films were calculated. The present study showed that size and the refractive indices of films can be controlled by the heat treatment. Therefore, such films can be a good candidate in optical filter applications

Traditional clothings of Greek Orthodox women immigrants who immigrated from Turkey to Greece at the “1923 Greek-Turkish population exchange”

Göç eylemleri ile topluluklar, yaşadıkları yerlerden yaşayacakları yeni yerlere ulaşırken sadece kendilerini değil, bu serüvende sahip oldukları kültürlerini de beraberlerinde götürerek, yeni bir etkileşim sürecinin hazırlayıcısı olurlar. Bu etkileşim sürecinde göçmenler ile yerel topluluklara ait olan kültürel değerlerin yeniden şekillenmesi durumu gündeme gelmektedir. Söz konusu durum, göç eylemlerinin toplulukların giyim-kuşam anlayışlarına ait etkisini doğrudan göstermekle birlikte, göçmen toplulukların sahip olduğu giysilere ilişkin kültürel değerlerin bir göstergesi olarak karşımıza çıkmaktadır. Bu araştırmada; Atina "National Historical Museum"da "1923 Türk-Yunan Nüfus Mübadelesi" döneminde Yunanistan'a göçen Ortodoks Rum kadın göçmenlerin giysilerine ait özelliklerin incelenmesi amaçlanmıştır. Türk ve Yunan topluluklar için önemli bir göç olayı olarak gösterilebilecek "1923 Türk-Yunan Nüfus Mübadelesi" öncesi dönemde, "Giresun (Kerasounta)", "Nevşehir (Neapolis)" ve "Kırklareli-Kavaklı (Saranta Eklesies-Kavakli)" bölgelerinde yaşamış olan Rum kadın göçmenlere ait giysiler; alanın gerektirdiği bir sistematikle; biçim, form, süsleme ve kuşanma biçimleri açısından ele alınmıştır. Giysi bütünlüğünü oluşturan giysi parçalarının biçimsel özelliklerinin grafik çizimleri yapılmış, bu özellikler ilgili literatür ve kaynak kişilerden edinilen bilgiler doğrultusunda tanımlanmıştır. Araştırma, Yunanistan'ın en önemli giysi arşivlerinden birine sahip olan "National Historical Museum" giysi koleksiyonu envanterindeki "1923 Türk-Yunan Nüfus Mübadelesi" ile Türkiye'den Yunanistan'a göç eden Ortodoks Rum kadın göçmenlerin geldikleri yerlerde kullandıkları giyim-kuşam özelliklerini içermesi, mevcut kültürel kimlikleri yansıtması ve belgelendirmesi açısından önem taşımaktadır. Ayrıca çalışma, maddi kültür miraslarının belgelenerek gelecek kuşaklara aktarılmasına katkı sağlamak ve bu konuda çalışma yapacak kişi ve kuruluşlara kaynak oluşturmak açısından da önemlidir.With immigrations, while communities are reaching to the new places where they have lived before, they carried their cultural values to their new settlements creating a new interaction process. In this interaction process, reshaping of cultural values of the immigrants and the local communities appear. The situation in question directly shows that immigrations effect clothing insights of the communites and it additionally emerges as an cultural indicator of the clothing that immigrant communities have. In this research, clothing features of Greek Orthodox women immigrants who immigrated from Turkey to Greece in the period of “1923 Greek-Turkish Population Exchange” which are being exibited at the “National Historical Museum” in Athens are aimed to be examined. Clothings of the Greek Orthodox women immigrants who lived in “Giresun (Kerasounta)”, “Nevşehir (Neapolis)” and “Kırklareli-Kavaklı (Saranta Eklesies-Kavakli)” regions before the “1923 Greek-Turkish Population Exchange” which is a very important immigration, were discussed in terms of form, ornamentation and dressing styles with the systematic requirements of the field.

Sonuç olarak nadir olarak rastlanan kranial torakal spondilozis deformans olgusunun klinik hekimliği yapan meslektaşlarımızla paylaşmanın klinik pratiğe katkı sağlayacağı düşünülmektedir.The material of this case report was consisted of a 5-years-old boxer male dog. In the anamnesis information obtained, it was learned that the patient was reluctant and felt pain while walking and going up and down the stairs, had incoordination disorder in the front extremities, and walked wobbly. In the clinical and orthopedic examination, no fracture or dislocation findings were found in the extremities. It was observed that he gave pain responses during the examination. In the thoracic LL, VD and abdominal LL radiographs of the patient, bone growths were detected between the vertebrae. Bone growths in the form of bridging were observed between the thoracic and lumbar T3-T4, T4-T5, T5-T6 and L2-L3, L4-L5, L6-L7 vertebrae. In the treatment, Prednol was administered at a dose of 2 mg/kg, IV on the first day and IM on the next two days. Every other day, B-complex vitamin support was provided and physical therapy was recommended. As a result, it is thought that sharing a rare case of cranial thoracic spondylosis deformans with our clinical colleagues will contribute to clinical practice

Pediatric Tracheotomy: A Relatively Rare Indication Limited to Pediatric Intensive Care Subjects?

Objective:To evaluate indications, underlying conditions and outcome in pediatric tracheotomy subjects.Methods:Between January 2004 and September 2013, pediatric subjects who underwent a tracheotomy operation were included for study. All subjects were under the age of 14. Subjects’ primary diseases, indication of tracheotomy, age, gender and type of complications were recorded.Results:Forty five subjects were identified. The mean age of subjects was 26.3 months (range between 2 to 140 months). Twenty one (46.6%) subjects were under the age of 1 year. In 34 (75.5%) out of 45 subjects, tracheotomy indication was prolonged intubation. In the remaining 11 (24.4%) subjects, tracheotomy indication was upper respiratory tract obstruction. Thirteen (n=13- 28.8%) out of 45 experienced early complications and 2 (n=2-4.5%) out of 45 subjects experienced late complications. One tracheotomy related death occurred in the immediate period. Eight (18.1%) of subjects died during the study period from underlying conditions. Decannulation was successfully performed in 13 (36.1%) subjects. In the remaining 23 (63.8%) subjects, decannulation could not be done.Conclusion:All tracheotomies in this report were performed on pediatric intensive care subjects on an elective basis. No tracheotomy was performed for acute upper airway obstruction. Even when planned and elective tracheotomy is performed it still has significant mortality and morbidity
