Management of maternal ventriculo-atrial shunt malfunction during pregnancy

Interdisciplinary Neurosurgery, 2016
Hydrocephalic females reaching childbearing age is increasing due to treatment advances. It has been suggested that ventriculo-atrial (VA) shunts be preferred over ventriculo-peritoneal (VP) shunts during pregnancy.

Thermal budget of superconducting digital circuits at sub-kelvin temperatures [PDF]

, 2005
Superconducting single-flux-quantum (SFQ) circuits have so far been developed and optimized for operation at or above helium temperatures. The SFQ approach, however, should also provide potentially viable and scalable control and read-out circuits for ...

Thermal behavior of parasitic resistances of polycrystalline silicon solar cells

Revue des Énergies Renouvelables, 2013
In this work, we investigate the influence of temperature on the series and shunt resistances of polycrystalline silicon solar cells and then to determine the specific expressions of both parasitic resistances as function of temperature.

Optimal sizing of C-type passive filters under non-sinusoidal conditions [PDF]

, 2014
In the literature, much attention has been focused on power system harmonics. One of its important effects is degradation of the load power factor. In this article, a C-type filter is used for reducing harmonic distortion, improving system performance ...
