Muchas personas, cada día más, se interesan por los temas concernientes al firmamento, a ese cielo estrellado que podemos ver en una noche oscura y a los fenómenos que en él ocurren. El mundo de la Astronomía es tan amplio, abarca tantos aspectos interrelacionados, que parece conveniente tener a mano un compendio de los conocimientos existentes al respecto, aunque de forma precisa pero sucinta, de fácil lectura y asequible a aquéllos que quieran iniciarse en este fascinante Universo que nos rodea. Más de 100 imágenes a color complementarias al texto, ayudarán sin duda, al lector, a...

Este pequeño volumen procura subrayar la importancia del desarrollo infantil. El mismo, comprende las primeras etapas que van de los 0 a los 6 años. Pone el acento en los diversos y muy estimulantes entornos que vive y presencia el bebé. Intenta, con la debida humildad, mostrar la trascendencia de este gran periodo.

This thesis (written in Spanish) presents the analysis, design and implementation of a four-quadrant power supply with high-frequency isolation, which is expected to be used to feed the low-energy correction magnet of a particle accelerator. In particle accelerator applications the magnetic field during beam acceleration may be either positive or negative, and true bipolar power converters are needed. The selected bipolar topology consists of a bidirectional three-phase to single-phase reduced matrix converter (RMC) with power factor correction and a bidirectional active rectifier. Main...

Behind the appearance of an innovative vaccine there is a history of determination and struggle, of breaking established models, and of overcoming the mistrust that generates a new theory. In this book we are going to learn about those stories, the stories of great scientists who fought to prove new theories and are now behind vaccines that save or will save millions of lives. We will experience with them the moment when they discovered that they had defeated a virus. We will travel inside the infectious agents to learn about their ability to gain ground in humans, the biological tools they...
