Design and Analysis of Pelton Wheel Bucket

ABSTRACT Pelton turbines are hydraulic turbines which are widely used for large scale power generation. A micro hydelpelton turbine is miniature model of actual pelton turbine which can be used for small scale power generation. This type of turbines converts potential energy of water at height into kinetic energy by allowing the water to fall freely on the pelton runner. This water impact provi...

Full integration of energy conversion devices for compact power supply circuits is still encountering strong technological locks, especially to integrate passive inductive and capacitive components. The increasing working frequency of those devices, which already reaches 1 Megahertz, would enable the size reduction of passive components and then their integration. Nevertheless, losses, which hi...

Rhabdomyosarcome ou pseudotumeur inflammatoire

Il s’agit d’un enfant de 4 ans, sans ATCD pathologique particulier, qui présente depuis 2 mois une tuméfaction inflammatoire, douloureuse, rapidement progressive de l’œil gauche.
