Integrazione scolastica e sociale dei disabili visivi

Il supporto dell’informatica non sostituisce la ricchezza della comunicazione interpersonale e la fatica di esplorare il mondo, ma integra e potenzia gli strumenti e le metodologie tradizionali

Innovazione tecnologica e promozione dell’apprendimento linguistico da parte di allievi ciechi e ipovedenti

The results of the COMENIUS - ELLVIS project contribute to promote and improve the access for people with visual impairments to language learning. As good learning material for visually impaired children is rare this innovative material opens up new possibilities for this target group and makes it possible for vi children to take part in lifelong learning. The project has been developed starting from the results achieved by the former project ALLVIP, in which DAA Germany has developed – together with a wide European partnership – a multimedia interface for interactive learning of languages (specifically English) by the identified target group. The course has successfully been tested by five training institutions for the blind and visually impaired people in Germany. The project ELLVIS aimed to amplify the innovative results of the former project by transferring the methodology and the new designed technology to the involved partner countries (Italy, France and Romania). Each partner has adapted, modified and integrated the software (audio files for lessons, grammar instructions, instructions for using the software) taking into account the different difficulties of learning English by the target group of each mother language. Four language schools and three institutions and their schools for blind and visually impaired people worked together to achieve the objectives, namely creating, testing, validation and dissemination of results

Pollutants abatement in aqueous solutions with geopolymer catalysts: A photo fenton case

: Environmental pollution is a serious threat to human health and the natural environment, and it has aroused widespread concern. One of the most effective processes in the removal of pollutants from wastewater is the Fenton reaction. This process is based on the production of highly reactive •OH radicals due to the rapid reaction between Iron ions and hydrogen peroxide under acidic conditions. The hydroxyl radical has a high oxidation potential of E°(•OH/H2O) = 2.8 V/SHE at acidic pH, so they are extremely reactive and non-selective oxidizing agent towards organic contaminants in wastewater. In order to avoid the drawbacks of a standard Fenton reaction, a photo Fenton reaction has been tested working at neutral pH in water in the removal of refractory pollutants. For the first time, a heterogeneous system was experimented, impregnating porous metakaolin-based geopolymers, obtained by using hydrogen peroxide and vegetable oil in different ratios, as foaming agents, with iron working as photocatalyst. The dirty wastewater as scrubber water (SCRW) and liquid fraction of digestate (LFD) were tested obtaining 40-90% abatement of Total Carbon Content
