Öğe Nonisocyanate polyurethane/silica hybrid coatings via a sol-gel route(Wiley-Hindawi, 2012) Hosgor, Z.; Kayaman-Apohan, N.; Karatas, S.; Gungor, A.; Menceloglu, Y.Polyurethane/silica hybrids by a nonisocyanate route were prepared by reacting cyclic carbonate-modified bis(4-glycidyloxy phenyl)phenyl phosphine oxide (BGPPO), and poly(propyleneglycol)diglycidyl ether (PPG-DGE) with hexamethylene diamine. The incorporation of silica was achieved via a solgel method. The effect of silica and phosphine oxide moiety on polyurethane coating properties was studied by physical, mechanical, and thermal tests. Modulus and hardness of the coatings were enhanced by increasing the amount of silica and phosphine oxide based resin. The improvement in flame retardancy and thermal stability of nanocomposites was proved with increased char yield values and decomposition temperatures in thermogravimetric analyses.

DOI 10.1002/adv.20262Öğe Traumatic rupture of giant pulmonary hydatid cyst in a child(Medcom Ltd, 2010) Karamustafaoglu, Y. Altemur; Gungor, A.Introduction: Trauma as a cause of hydatid cyst rupture leads to various clinical conditions, especially in children. Current literatures regarding the clinical presentation and management of such patients are rare. Case report: A 14-year-old child was admitted with chest pain and dyspnoea due to blunt thoracic trauma after falling off a bicycle. Chest computed tomography showed right hydropneumothorax and cystic cavity. After chest tube insertion, massive air leak was observed from the tube. Cystotomy and capitonnage were performed on the right lower lobe via a posterolateral thoracotomy. He was discharged from the hospital in good condition. Conclusion: Ruptured hydatid cysts into the pleura are difficult to diagnose radiologically. It can be misdiagnosed radiologically as empyema or hydrothorax. In undetermined cases, all the findings may be suggestive but not diagnostic. Operation must be performed early for exploration when the condition is suspected. High complication rate has been found in children who were operated late. (Hong Kong j.emerg.med. 2010;17:381-383)
