Peripheral vision by a real time 3D system for analysing dynamic scenes

Many applications in robotics need enhanced vision systems able to give a reliable 3D information of the focused objects in a dynamic scene context . In this paper we propose a complete system (including the conception of sensors, their disposition and th e information processing) for observing a scene in a peripheral way, this means that it will cover 360° of angle, and for evaluatin g the observed objects' distances .De nombreuses applications en robotique exigent des systèmes de vision de plus en plus performants permettant de restituer l'espace 3D observé le plus fidèlement possible et dans un contexte de scène dynamique. Dans cette contribution on propose un système complet temps réel (comprenant la conception des capteurs, leur disposition, et le traitement informatique de l'information) visant à observer une scène de façon périphérique, c'est à dire couvrant 360° d'angle, et à évaluer les distances des objets observés

Modulation of mitochondrial F0F1 catalysis by boundary and bulk phase phospholipids.

The importance of boundary and bulk phase phospholipids was studied on a mitochondrial ATPase complex isolated by AH-Sepharose chromatography as described by Dreyfus et al (1984, Anal. Biochem. 142,215-220), this preparation was devoid of the adenine nucleotide carrier. The presence of isoelectric or acidic phospholipids during the purification in the column allows the exchange of tightly bound phospholipids up to 95%. ATP hydrolysis and oligomycin sensitivit
