Recull d'experiències portades a terme en diferents escoles d'educació infantil i primària per a mestres interessats a fomentar en el seu alumnat conceptes químics a partir d'experiències quotidianes (la festa de la castanyada, els caramels, els gelats, el most).
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.

Mediterranean islands exhibit many similarities in their biotic ecological, physical and environmental characteristics. There are also many differences in terms of their human colonization and current anthropogenic pressures. This book addresses in three sections these characteristics and examines the major environmental changes that the islands experienced during the Quaternary period. The first section provides details on natural and cultural factors which have shaped island landscapes. It describes the environmental and cultural changes of the Holocene and their effects on biota, as well as on the current human pressures that are now threats to the sustainability of the island communities...
The 1960s were perhaps a decade of confusion, when scientists faced d- culties in dealing with imprecise information and complex dynamics. A new set theory and then an in?nite-valued logic of Lot? A. Zadeh were so c- fusing that they were called fuzzy set theory and fuzzy logic; a deterministic system found by E. N. Lorenz to have random behaviours was so unusual that it was lately named a chaotic system. Just like irrational and imaginary numbers, negative energy, anti-matter, etc., fuzzy logic and chaos were gr- ually and eventually accepted by many, if not all, scientists and engineers as fundamental concepts, theories, as well as technologies. In particular, fuzzy systems technology has ...
This title takes an interdisciplinary approach to the central role of solubility in pathological biomineralisation, ranging from traditional thermodynamics and kinetics to unusual concepts such as the PILP process. The scientific background and expertise of the contributors, ranges accordingly from solubility modelling and database development, renal stone and bone implant research, Mössbauer spectroscopy and structural chemistry to biochemistry and crystallisation. The chapters all have a quantitative, physico-chemical component rather than giving purely phenomenological descriptions. The contributors deal with aspects and concepts that have not previously been common in the study of pathological biomineralisation processes.
