Background: The prevalence of behavioral problems is significantly high in children with epilepsy compared to children with other chronic illnesses which do not affect the central nervous system. Attention Deficit Hyperactivity Disorder (ADHD) is a common comorbid disorder with epilepsy. Thus, children with epileptic seizure are in increased risk of cognitive disorders particularly attention pr...

Unsuccessful percutaneous mechanical thrombectomy in fibrin-rich high-risk pulmonary thromboembolism
BACKGROUND We report a case of unsuccessful percutaneous mechanical thrombectomy in treatment of a high-risk pulmonary embolism (PE). Pulmonary thromboemboli are commonly expected as a homogenous mass, rich with red blood cell content, which respond well to percutaneous mechanical thrombectomy (PMT). Catheter-based approach or surgical embolectomy are two treatment options that are usually cons...
In this note we examine the change of the PMT pulse gain as a function of DC background current using an active divider and compare its behavior to the one obtained using a passive network. We show that the present version of the active divider results in: 1) constant gain over a large background current (rendering possible to operate the FD under the presence of some backscattered moon light, ...
We have measured the performance, especially the timing properties, of micro-channel plate photo-multiplier tubes (MCP-PMTs) by irradiating with single photons with/without a magnetic field. A time resolution of s 1⁄4 30–35 ps was obtained for single photons under 1:5 T: With an MCP-PMT, a small time-of-flight counter, by means of Cherenkov light radiation instead of scintillation light has bee...
Falls during daily activities are often associated with injuries and physical disabilities, thereby affecting quality of life among elder adults. Balance control, which is crucial in avoiding falls, is composed of two elements: muscle strength and central nervous system (CNS) control. A number of studies have reported that reduced muscle strength raises the risk of falling. However, to date the...
Electrical energy is a necessity that needed by everyone. To ensure the reliability of electrical energy, equipment used must be regularly maintained. One maintenance carried out testing SF6 gas on power breaker (PMT). This test to determine quality which functions as an insulation medium for PMT. Because when there fault current or normal at time PMT cut off, arc will arise can damage itself. ...
