Introduction In radiography, dose and image quality are dependent on radiographic parameters. The problem is caused from incorrect use of radiography equipment and from the radiation exposure to patients much more than required. Therefore, the aim of this study was to implement a quality-control program to detect changes in exposure parameters, which may affect diagnosis or patient radiation do...

In this work, a novel Silicon on Insulator (SOI) MOSFET is proposed and investigated. The drain and source electrode structures are optimized to enhance ON-current while global device temperature and hot carrier injection are decreased. In addition, to create an effective heat passage from channel to outside of the device, a silicon region has embedded in the buried oxide. In order to reduce th...

Introduction: In this study, we sought to illustrate our experience in urgent surgical management for embolized cardiac septal occlude devices resulting from trans-catheter closure of atrial septal defect and ventricular septal defect. Mathrials and Methods: We retrospectively reviewed four patients aged 2–10 years who underwent urgent surgery due to cardiac septal occluder embolization between...

In this article, we report the studies of various device architectures of organic lightemitting devices (OLEDs) incorporating highly efficient blue-emitting and ambipolar carriertransport ter(9,9-diarylfluorene)s, and their influences on device characteristics. The device structures investigated include single-layer devices and multilayer heterostructure devices employing the terfluorene as one...
