El objetivo de este trabajo es mostrar los por qué de la perspectiva que sobre el proceso de renovación urbana tienen los habitantes del barrio de la Boca. Esto guarda una especial relación con los mecanismos de preservación y transformación del patrimonio cultural barrial. Para ello, se analizarán las actitudes de estos tres grupos de dirigentes barriales: aquellos que lideran organizaciones sociales tradicionales del barrio, los referentes de comedores comunitarios, de reciente formación, y los líderes de organizaciones de perfil reivindicativo, surgidas en torno al tema de la vivienda y otros componentes del hábitat.______________________ABSTRACT:The aim of this paper is to show the reasons of the perspective of the inhabitants of “la Boca” district on the urban renewal process. This maintains a special relation with the mechanisms of preservation and transformation of the cultural heritage of the district. This is why the author analyses the activities of the following three local charity organisation leaders: those who lead the traditional social organisations of the district, the recently trained referents of the community dining halls and the leaders of protest organisations that developed around the subject of housing and other elements of the environment.

Un sito web che consente di scegliere dove e come installare un nuovo impianto da fonte rinnovabile e valutarequanto sarà redditizio in base alla risorsa naturale (sole o vento) effettivamente disponibile nella località desiderata.Il servizio si basa su uno storico di dati di irradianza e di intensità del vento, dedotti sia da osservazione satellitareche da rilevazione da centraline al suolo. A web site developed to allow users to choose where to place a new renewable energy plant It is here presented a web site developed to allow users to choose where to place a new renewable energy plant and to evaluate its profitability on the basis of the natural resource (sun or wind) actually available in a selected location. The service is based on historical data of sun irradiance and wind intensity, got from both satellite remote sensing and ground stations. It combines the satellite technology with the availability of environmental models for the ground solar radiation analysis and PV-modules models; therefore it allows the producibility analysis, the design and the on-line estimation of new plants, providing a detailed budget with economic and technical in-formation. Moreover is described a solar plant production monitoring system based on current satellite solar radiation data updated every few minutes. The full system has been de-veloped by means of both proprietary and free technologies such as Google Maps, Gdal libraries, PostgreSQL database and the Microsoft ASP.Net Framework.
