Its clinical diagnosis involves poor attention, distractibility, difficulties to inhibit motor(More)
Cerebral ischemia due to low cerebral perfusion pressure (CPP) is the most important secondary effect of severe head injury. There is consensus regarding the maintenance of this pressure at levels above 70 mm Hg. One way to elevate CPP is by increasing mean arterial pressure (MAP). In this study, the authors attain this target by using adrenergic(More)
In terms of volume, transformers are the most important components of switch mode power supplies (SMPS). When moving towards higher frequencies in order to reduce the converter volume, the impact of high-frequency (HF) effects in the windings increases. This paper proposes a transformer design methodology that takes into account these HF effects in solid(More)
