Química en infantil y primaria : una nueva mirada
Este libro muestra una selección de experiencias llevadas a cabo en diferentes escuelas de educación infantil y primaria para maestros interesados en fomentar en su alumnado conceptos químicos a partir de experiencias cotidianas que, a veces, no se analizan directamente desde esta perspectiva (la fiesta de la castañada, los caramelos que recogimos en una cabalgata, el mosto que nos llevamos de las colonias, el pan hecho y cocido en el horno de la escuela, los helados que hicimos sin congelador...) pero que demuestran cómo la química contribuye a comprender y gestionar con responsabilidad el mundo que compartimos.
Mechanisms and Phylogeny of Mineralization in Biological Systems
Various kinds of mineralization have been found in many biological systems. Investigations made at a microscopical level using various sophisticated analytical methods and using principles developed in different fields have clarified their mechanisms very much. Sometimes, very similar phenomena have been found in the mineralized tissues of completely different biological systems. Compilation and comparative investigations of such findings obtained from the many specimens systematically collected contribute a great deal to an understanding of the crucial mechanisms and significance of biominerali zation which originated in very primitive organisms and remain in advanced ones. Previously, the ...
Ground Improvement, Third Edition
When finding another location, redesigning a structure, or removing troublesome ground at a project site are not practical options, prevailing ground conditions must be addressed.

This third edition of Ground Improvement provides a comprehensive overview of the major ground improvement techniques in use worldwide today. Written by recognized experts who bring a wealth of knowledge and experience to bear on their contributions, the chapters are fully updated with recent developments inclu...

General Jacob Devers
A “solid and informative” biography of one of the overlooked heroes of the Second World War (Wall Street Journal). Of the leaders of the American Army in World War II, Jacob Devers is undoubtedly the “forgotten four-star.” Plucked from relative obscurity in the Canal Zone, Devers was one of four generals selected by General of the Army George Marshall in 1941 to assist him in preparing the Army for war. He quickly became known in Army circles for his “can do” attitude and remarkable ability to cut through red tape. Among other duties, he was instrumental in transforming Ft. Bragg, then a small Army post, into a major training facility. As head of the armored force, Devers contrib...
