Máquina eléctrica es un dispositivo que transforma la energía eléctrica en energía mecánica, o bien, en energía eléctrica con características distintas, pasando esta energía por una etapa de almacenamiento en un campo magnético. Se clasifican en tres grandes grupos: generadores, motores y transformadores. El objetivo general del libro es proporcionar los conocimientos teórico prácticos para entender las máquinas eléctricas y sus técnicas de de control, de manera clara y objetiva.

South American camelids (Llamas, Alpacas, Vicuñas and Guanacos) are receiving increased interest not only in South America but also on a worldwide scale. They possess some unique features such as their fine fibre and healthy meat, and their high adaptivity to many climatic regions across the world. Apart from the important productive aspects, their physical attractiveness and friendly temperament also makes them popular as pet animals. There are still many gaps in the scientific literature with regard to South American camelids. In part, this gap can be diminished by this collection of...

Underground structures must be able to support static overburden loads, as well as to accommodate additional deformations imposed by seismic motions. It seems well established that the most critical demand to the structure is caused by shear waves traveling perpendicular to the tunnel axis, which cause distortions of the cross section (ovaling for a circular tunnel, and racking for a rectangular tunnel) that result in axial forces (thrusts) and bending moments. While all this has been well-studied for structures placed in linear-elastic ground under drained loading conditions, there is little ...
