BACKGROUND To evaluate internal fixation by intramedullary Kirschner wires as a surgical technique in the treatment of femoral shaft fractures in children by a prospective study. METHODS 17 femoral shaft fractures at various levels in 16 children aged 2-15 years were treated by closed intramedullary Kirschner wiring under image intensifier control between May 2000 and October 2003. No externa...

The quest to replace toxic chemicals in the nearest future is revolutionizing corrosion inhibitor research world by turning its attention plant biomaterials. Herein, we report inhibiting potential of butanolic extract date palm leaves (BUT) on API 5L X60 carbon steel 15 wt.% HCl solution. mass loss, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), linear (LPR), ...

BACKGROUND Image intensifiers have become popular due to the concept of minimally invasive surgeries leading to decreasing invasiveness, decreased operative time, and less morbidity. The drawback, however, is an increased risk of radiation exposure to surgeon, patient and theatre staff. These exposures have been of concern due to their potential ability to produce biological effects. The presen...

Introduction: Previously we have published data showing how clinician awareness surrounding radiation doses from common diagnostic modalities is poor. Evidence suggests that radiation exposure, from diagnostic and interventional procedures is placing patients at a small but significant increased risk of malignancy. As the usage of radiation in endourological surgery increases, urologists need t...

The fusion and enhancement of multiband nighttime imagery for surveillance and navigation has been the subject of extensive research for over two decades. Despite the ongoing efforts in this area there is still only a small number of static multiband test images available for the development and evaluation of new image fusion and enhancement methods. Moreover, dynamic multiband imagery is also ...

the present study explored the intensity level of authorial voice in relation to the quality of argumentative writing. 42 undergraduate learners of english as a foreign language (36 girls and 6 boys) spent 45 minutes to individually complete in-class position-taking writing tasks for three weeks. their overall academic writing quality scores assigned based on portfolio assessment were studied i...

A large number of investigations into the radiation doses from x-ray guided interventional cardiology procedures in children have been carried out in recent years. A review was conducted of these studies, gathering data on kerma area product (P KA), fluoroscopic screening time (FT), air kerma, and estimates of effective dose and organ doses. The majority of studies focus on P KA and FT with no ...

Alkali antimonide photocathodes are a strong contender for the cathode of choice for next-generation photon sources such as LCLS II or the XFEL. These materials have already found extensive use in photodetectors and image intensifiers. However, only recently have modern synchrotron techniques enabled a systematic study of the formation chemistry of these materials. Such analysis has led to the ...

Vacuum based devices, such as Photo Multiplier Tubes (PMT) and Micro Channel Plates (MCP), have been for many years the sensors of choice for most applications calling for photon counting and timing (Renker, 2004). While providing very good sensitivity, noise and timing characteristics, these photodetectors feature a number of disadvantages: they are bulky, fragile, and sensitive to magnetic fi...
