introduction: limited data are available on the effectiveness of antidepressants in the treatment of functional gastrointestinal disorders in children. we evaluated the effectiveness of citalopram in the treatment of childhood functional abdominal pain (fap).   material and methods: children with fap (n=115, aged 6-18 years) received either citalopram 20 mg/day or placebo for 4 weeks. treatment...

Tension Pneumothorax Tension pneumothorax occurs when a one-way valve develops in the injured lung and allows entry of air into the pleural space during inspiration without being able to escape during expiration. Tension physiology occurs when the increased intrathoracic pressure (15 to 20 mm Hg) limits the return of venous blood flow from the body to the right heart and compresses the great ve...

In this paper, we present a low power high temperature 80C51 microcontroller. The low power optimizations are applied at gate and architectural level, by using extensive clock and data gating, and by completely redesigning the micro-architecture. We also present original clock gating techniques: pre-computed clock gating. To validate these techniques, extensive comparisons with other realizatio...
