1. Control system for continuous positive airway pressure
INTRODUCTION: Continuous Positive Airway Pressure (CPAP) is a mode of non-invasive mechanical ventilation commonly used in neonatology. The incorporation of new therapeutic and technological advances may impact the survival of very low birth weight preterm infants. However, one of the difficulties faced is the high cost of this device and its numerous add-on

2. POSITION CONTROL OF A CARTESIAN ROBOT THROUGH ADAPTIVES TECHNIQUES / Controle de posição de um robô cartesiano por meio de técnicas adaptativas
Neste trabalho apresentam-se projetos de um controlador adaptativo preditivo e de um híbrido para um robô manipulador eletropneumático de três graus de liberdade (3 GDL) cartesiano. O robô manipulador é composto basicamente por três válvulas eletropneumáticas e por três cilindros pneumáticos, dois de 500mm formando o plano XZ e um de 400mm no eixo

3. SISTEMA DE REGULAGEM DO ESFORÃO DE CORTE EM CHAPAS METÃLICAS COM VARIAÃÃO DE ESPESSURAS / SYSTEM OF REGULATION OF THE CUT EFFORT IN METALLIC PLATES WITH VARIATION IN THICKNESSES
This work presents the project of a system that can be applied under a punching operation with different thickness metal plates and the pressure variation, knowing that is one of the most used process in the mechanical industry conformation, it reaches the most efficient results applied to the studied process. The main is to consider a electropneumatic syste

4. The interaction between noradrenaline activation and distension activation of the rabbit ear artery.
Excised, pressurized segments of the rabbit ear artery have been used to examine the interaction between the transmural pressure and constriction of arteries by extraluminal noradrenaline. The bath temperature was kept at 32-33 degrees C to suppress instability and spontaneity of constriction. Fast, reproducible jumps in pressure were obtained by using a mic
