Science learning for blind people is limited. For a variety of reasons there is a very low emphasis on science learning for such users, especially those from deprived communities. We have designed, implemented and evaluated the usability of AudioNature, an audio-based interface implemented for pocketPC devices to assist with science learning in users with(More)

Este estudio consistió en diseñar, desarrollar y evaluar ConceptGame, un videojuego para generar aprendizaje a través de la cons-trucción de representaciones conceptuales de una disciplina, utilizando la técnica de los mapas conceptuales. Para entender cómo los aprendices percibían e interactuaban con el videojuego, se realizaron pruebas preliminares de(More)
Extracellular matrix (ECM) is a rich network of proteins and proteoglycans that has proved to be very useful in tissue regeneration. Porcine ECM has been proposed as a biological scaffold, and urinary bladder matrix (UBM) has demonstrated superior biological properties; however, its use in human treatment requires ensuring that it is DNA free.
