BT2014634 Art. Réparation de molasse par une pierre artificielle
- Write a review
Résumé
Des pierres artificielles produites à partir de poudre de pierre et de résine acrylique ont été utilisées lors de la restauration de léglise catholique Notre-Dame de Vevey (Suisse) pour le reprofilage de molasse, un grès largement utilisé dans les monuments suisses. Une campagne de mesure sur ce site a débuté en juillet 2013 pour quantifier les conditions environnementales auxquelles sont exposées les pierres artificielles et naturelles. Des mesures de température et dhumidité relative sont effectuées depuis la surface jusquà une profondeur de 6.7 cm dans le mur, sur une façade ouest exposée à des cycles de mouillage et séchage. Les quantités de pluie battante, ruisselante et absorbée dans la pierre sont également mesurées. Cette communication présente le dispositif de mesure utilisé et les premiers résultats obtenus pendant les mois dété et dhiver 2013. Leur implication en termes de durabilité dans les pierres naturelle et artificielle est considérée.

Past ten years, literature is an increasing number of works trying to identify the different levers to operate to encourage innovation within companies. In continuation of this work focused on the emergence of a "culture of innovation," the state of the art made in this article allows us to bring about a feeling of "psychological safety" is the only means that:
- Members of the organization are not paralyzed by fear of failure and continue to offer bold initiatives,
- These players learn from the mistakes that will inevitably be committed during the innovation process and are able to no longer reproduce. We suggest, as such, some lines of thought to create a culture of "room for error" in organizations, starting with the consolidation of the reward and sanction systems by the inclination of the direction to "Legends" failures. We stress however that this may be possible in the context of American culture is not necessarily in that of French culture.
