The explosive growth of science and medicine in recent times has raised a host of ethical issues. This book reviews major advances in biology and medicine and explores their ethical implications. Organized by stage of human life--from birth to death--it guides the reader through the critical issues that face our technologically advanced society. Each section contains a sketch of the scientific research in a particular field and then discusses the issues that challenge our ethical and moral principles, social frameworks, and public policies. A world-class group of contributors from biology,...

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...

Max Born afirmó que, aunque Albert Einstein no hubiera escrito una sola línea sobre relatividad, habría sido igualmente uno de los científicos más grandes de todos los tiempos. Este libro, escrito de forma accesible por uno de los especialistas más reconocidos en el campo, explora de forma accesible la cuantía y envergadura de las contribuciones científicas de un Einstein no relativista —un Einstein, por tanto, casi "desconocido"— en terrenos como las fuerzas moleculares, la termoestadística, el efecto fotoeléctrico, el movimiento browniano, la opalescencia, los cuantos de...
