Ejemplo del interés que Charles Darwin mostró por la Geología es que la primera ediciónde su viaje se publicó en 1839 como Diario de las investigaciones en Geología e Historia Natural de los distintos paises visitados por el Beagle. Ayuda a explicar su preocupacion, ademas de la elocuencia con que en America la naturaleza ofrece las manifestaciones de la historia geologica del planeta, el impacto que en el joven cientifico tuvo el ser testigo privilegiado de alguna de las mas dramaticas expresiones de la vitalidad de la tierra, entre ellas, las que llama escenas magnificas, como los volcanes en actividad y los efectos aterradores de un terremoto. Prueba de su pasion por la Geologia es el libro Observaciones geologicas en America del Sur. Junto con este, en esta edicion se reproducen cuatro articulos escritos por Darwin, o sobre la base de sus cartas y presentaciones, relacionados con la geologia de America, asi como las laminas, ilustraciones, graficos, esquemas y mapas que acompañan los escritos originales. Esta edicion permite, a la vez que recuperar una fuente fundamental para el estudio de la Historia Natural de America, conocer y valorar la practica geologica de un cientifico cuya obra biologica ha hecho olvidar que alguna vez fue tambien geologo. Y un gran geologo, tal como lo demuestra el estudio introductorio que acompaña el texto de Darwin.Edicion de Rafael Sagredo Baeza; introduccion de Rafael Sagredo Baeza y Francisco Herve Allamand; traduccion de Maria Teresa Escobar.

El lector encontrará en esta obra una descripción de los principios físico-químicos básicos que rigen las técnicas de análisis de contaminantes químicos. Las técnicas analíticas descritas son: métodos volumétricos, de espectroscopia atómica y molecular, de electroforesis capilar, de espectrometría de masas, y por supuesto, técnias cromatográficas en todas sus vertientes (de líquidos, gases, en capa fina, etc). El libro también contiene una imporatante sección dedicada a describir los procedimientos que deben aplicarse sobre la muestra objeto de análisis inmediatamente antes del análisis químico propiamente dicho.

En el año 1604 Kepler pudo contemplar con sus propios ojos la última supernova vista hasta el día de hoy, perteneciente a nuestra Galaxia. Rodolfo II insta a su Matemático Imperial a escribir sobre tan admirable fenomeno celeste y asi nace este magnifico libro, unico en muchos aspectos, que nos da a conocer, ademas de los hechos astronomicos del caso, el pensamiento y las opiniones de este pionero de la Astronomia moderna que, simultaneamente a la composicion de esta obra, descubria sus dos primeras leyes del movimiento planetario. Cuando todos los astrologos admiraban en el cielo nocturno el esperado Trigono Igneo, notable conjuncion de los planetas mayores, dispuestos en formacion triangular con los vertices orientados hacia las constelaciones de Aries, Leo y Sagitario, y que solo se presenta cada 800 años, alli, de la forma mas sorprendente se encendio, como presidiendolo todo, una nueva estrella (hoy la llamamos supernova), un astro refulgente, mas brillante que el resto. Han debido pasar mas de cuatrocientos años para que alguien se decidiera a acometer el trabajo, arduo y laborioso, de verter al idioma castellano esta obra salida de la pluma de Kepler. Esta magna tarea la ha realizado el Dr. D. Vidal Gonzalez Sanchez, historiador e investigador, autor de numerosas publicaciones, que traduce magistralmente y por vez primera del latin al español este libro haciendolo asi asequible a los 480 millones de hispanohablantes. Precede al texto un amplio estudio introductorio, por D. Nicolas Garcia Herrera. El Matematico y Astronomo Johannes Kepler, uno de los protagonistas imprescindibles de la Revolucion Cientifica del siglo XVII, es el primer cientifico que publica de forma explicita, precisamente en este libro, y en 1606, su aceptacion del sistema heliocentrico de Copernico (siete años antes de que lo hic

Tras la publicación de la Directiva 271/91 CEE en materia de depuración de aguas, una vez alcanzados unos mínimos en cuanto a exigencias de contaminación en los vertidos, el futuro hacia el que apunta la Directiva Marco del Agua es el de ir aun mas alla en cuanto a proteccion del entorno en materia de vertidos. Asi, la normativa en materia de nutrientes, cada vez mas exigente, las necesidades, normativa y oportunidad de la reutilizacion de aguas residuales, y la necesidad de ampliar muchas de las depuradoras existentes, hacen que en el momento actual en muchas ocasiones se requiera la implantacion de sistemas avanzados de tratamiento. En esta linea se presentan en este libro posibles sistemas de inertizacion biologica para la reutilizacion de aguas residuales que se estan utilizando en los actuales sistemas de desinfeccion en los tratamientos de aguas, asi como otros aspectos relacionados: legislacion, procesos avanzados, indicadores biologicos, limitacion de los distintos sistemas de desinfeccion, etc

La teoría de juegos analiza situaciones de decisión en las que los participantes interactúan. El resultado que obtiene cada agente depende tanto de sus propias acciones como de las decisiones de los demas, obligandoles, en ocasiones, a comportarse estrategicamente. La economia, la politica, las situaciones de conflicto y negociacion, el reparto de costes, entre otras, son areas en las que abundan este tipo de situaciones. Este libro, diseñado como soporte para un curso introductorio de teoria de juegos, recoge los conceptos e instrumentos basicos para analizar dichas situaciones interactivas. Ademas, sirve para tomar decisiones fundamentadas evitando las claramente incorrectas.

La colección Problemas útiles, aparece para tratar de cubrir la necesidad de libros que planteen problemas de examen o de dificultad similar, explicando al estudiante en detalle las trampas a las que suelen enfrentarse en un examen.
