1. Robert Frank e a operação de montagem no campo do olhar
In the Polaroids series photographer Robert Frank creates performed situations and manipulates the two-dimensional surface in a post-production condition, building images with uncertain borders where emptiness, words, pictorial gestures, appropriations and acts are highlighted. Emerging through mounting resources, these procedures question certain intrinsic

2. CONTROLE POR APRENDIZADO DE SISTEMAS SERVO: HIDRÁULICOS DE ALTA FREQÜÊNCIA / LEARNING CONTROL OF HIGH FREQUENCY SERVO: HYDRAULIC SYSTEMS
Hydraulic systems are used where relatively high forces and torques are required, or when high response speeds are necessary. They are used in industrial systems, robotics, movement simulators, automated plants, ore exploration, presses, and especially in fatigue testing systems. Fatigue tests are usually performed on servo-hydraulic systems, in order to pre

3. Morphometric investigations in mitral stenosis using two dimensional echocardiography.
A method is proposed for comparing the orifice size and the morphology of stenotic mitral valves, removed intact at the time of replacement, with the preoperative two dimensional echocardiographic cross-sections. The excised mitral valve apparatus is suspended on a specially constructed mounting. To avoid shrinkage the orifice is stabilised with an airfilled

4. Mitral valve replacement in dogs using pig aortic valve heterografts
Mitral valve replacement using pig aortic valve heterografts has been performed in 27 dogs, siting the grafts in the `atrial position'. Buffered acid formaldehyde sterilization offered the advantages that it is simple and, by de-naturing the proteins of the graft, may minimize `rejection' phenomena. It may offer some self-sterilizing property to the graft wi
