En el present projecte final de carrera s’han dissenyat i pressupostat les instal·lacions de fontaneria, energia solar i gas natural per abastir d’aigua les dependències d’un hotel. L’hotel es troba situat a municipi de Platja d’Aro, a la província de Girona. La seva categoria és de quatre estrelles i això comporta un nivell alt de qualitat en els serveis oferts, en aquest cas el subministrament d’aigua freda i aigua calenta sanitària (ACS) als seus clients

The identification of compositional changes in fumarolic gases of active and quiescent volcanoes is one of the most important targets in monitoring programs. From a general point of view, many systematic (often cyclic) and random processes control the chemistry of gas discharges, making difficult to produce a convincing mathematical-statistical modelling. Changes in the chemical composition of volcanic gases sampled at Vulcano Island (Aeolian Arc, Sicily, Italy) from eight different fumaroles located in the northern sector of the summit crater (La Fossa) have been analysed by considering their dependence from time in the period 2000-2007. Each intermediate chemical composition has been considered as potentially derived from the contribution of the two temporal extremes represented by the 2000 and 2007 samples, respectively, by using inverse modelling methodologies for compositional data. Data pertaining to fumaroles F5 and F27, located on the rim and in the inner part of La Fossa crater, respectively, have been used to achieve the proposed aim. The statistical approach has allowed us to highlight the presence of random and not random fluctuations, features useful to understand how the volcanic system works, opening new perspectives in sampling strategies and in the evaluation of the natural risk related to a quiescent volcano

La propuesta de modelo de formación del profesorado que seguidamente va a ser descrita1, basada en los nuevos planteamientos educativos referidos y diseñada en atención específica a la realidad de la Comunidad Autónoma andaluza -si bien generalizable en muchos aspectos a otras- y para la etapa concreta de Educación Primaria, ofrece pautas de actuación para el ámbito de conocimiento concreto de las ciencias experimentales, o lo que es lo mismo, para el relativo al del conocimiento del medio natural
