Abstract:
Effective daylighting can substantially reduce the energy use and greenhouse gas emissions of commercial buildings. Daylight is also healthy for building occupants, and contributes to occupant satisfaction. When productivity improvements are considered, effective daylighting is also highly attractive financially. However, successful daylighting of sub-tropical buildings is a very difficult task, due to high direct irradiances and excessive solar shading. A device was created that combined effective solar shading and efficient daylight redirection. The micro-light guiding shade panel ach

Abstract:
L'objectif de cette thèse est de tirer parti d'une illumination totalement ou partiellement contrôlée pour enrichir l'acquisition vidéo de contenus tel que la reconstruction de la forme et de l'apparence. Aujourd'hui de nombreux travaux ont tenté d'atteindre cet objectif. Certains utilisent une illumination contrôlée et séquentielle pour obtenir des reconstructions de haute qualité de la forme et de la réflectance. En revanche, ces méthodes requièrent des dispositifs coûteuses et/ou ne fonctionnent pas en temps réel. Dans cette thèse, nous visions un système d'acquisition à bas coût, rapide et

Abstract:
La fosforilazione reversibile di proteine tilacoidali negli organismi fotosintetici è un meccanismo per far fronte a condizioni di luce variabili. Nelle monocotiledoni, contrariamente a quanto avviene nelle dicotiledoni, è stato dimostrato che la fosforilazione dell’antenna minore CP29, in seguito ad esposizione ad alte intensità luminose, induce un incremento in NPQ e diminuisce la produzione di specie reattive dell’ossigeno (ROS). La chinasi del complesso di antenne maggiori (LHCII), denominata STN7, e la relativa fosfatasi TAP38/PPH1, non partecipano in questo meccanismo, come in precedenza
