OBJECTIVE Transposition of the great arteries is a common congenital heart disease. Arterial switch is the gold standard operation for this complex heart disease. Arterial switch operation in the presence of intramural coronary artery is surgically the most demanding even for the most experienced hands. We are presenting our experience with a modified technique for intramural coronary arteries ...

Migration of peritoneal catheter into the abdominal cavity is rare. We have discussed and presented the treatment options in two cases with accompanying literature. Abdominal migration of peritoneal catheter appears as a result of shunt fracture and disconnection. The complaints on presentation in the abdominal cavity migration of peritoneal catheter are due to shunt dysfunction and peritoneal ...

A 14 years old boy who had a ventriculo-peritoneal shunt since the age of 5 months, was hospitalized due to headaches, nausea, vomiting and abdominal distension. In abdominal CT and sonographic evaluation, pancreatic pseudocyst or mesentric cyst were suspected. Evaluation of the shunt by radionuclide, however, was diagnostic and revealed a pseudocyst at the peritoneal end of the shunt. Th...

Cells of Escherichia coli growing on sugars that result in catabolite repression or amino acids that feed into glycolysis undergo a metabolic switch associated with the production and utilization of acetate. As they divide exponentially, these cells excrete acetate via the phosphotransacetylase-acetate kinase pathway. As they begin the transition to stationary phase, they instead resorb acetate...

A stable, device specific, multiple energy domain and multi scale simulation tool for Radio Frequency (RF) MicroElectroMechanicalSystems (MEMS) devices is developed. A structured design methodology is adopted for design and optimization of RF MEMS shunt switch and MEMS inductor. The Computer Aided Design (CAD) tool incorporates physical parameters such as surface roughness. An electromechanical...

there are fewer problems encountered with optical voltage transducers in comparison with their inductive and capacitive counterparts. although capacitive and inductive transformers are used vastly for the purpose of measurement and protection in the networks, they cause problems such as core saturation and improper transient responses which decrease the accuracy of measurement and eficiency of ...

Radionuclide shuntography is a safe and simple method to determine shunt patency and analyze changes in CSF (Cerebro-Spinal-Fluid) flow. We present a case of complicated CSF shunt, in which radioisotopic scan correctly identified disconnection of the shunt tubing system localizing the site of extravasation accurately. The findings were confirmed by surgery performed for correction of the ...

The paper investigates the actuation mechanism in floating electrode MEMS capacitive switches. It demonstrated that in the pull-in state the device operation turns from voltage to current controlled actuation. The current arises from Poole-Frenkel mechanism in the dielectric film and FowlerNordheim in the bridge-floating electrode air gap. The pull-out voltage seems to arise from the abrupt dec...
