Mechanical seals continue to be the predominant technology for shaft sealing in centrifugal pumps and other rotating equipment. While most mechanical seals are designed to operate on a liquid film, there are options for designing seal faces which function reliably while operating on a hydrodynamic gas film. In a dual pressurized seal (Arrangement 3), gas seals can provide unique benefits in ter...

With the fast development of Cyber-Physical Systems (CPS), security in these special application environments starts to attract more and more efforts. In this project, we form a team of researchers in information security, manufacturing, mechanical engineering, and education to jointly design a remotely accessible experiment platform for security education in advanced manufacturing systems (AMS...

The overarching goal of positive pressure mechanical ventilation is to provide adequate gas exchange support while not causing harm. Indeed, positive pressure mechanical ventilators are only support technologies, not therapeutic technologies. As such they cannot be expected to "cure" disease; they can only "buy time" for other therapies (including the patient's own defenses) to work.Conventiona...

This review addresses how the combination of physiology, medicine and engineering principles contributed to the development and advancement of mechanical ventilation, emphasising the most urgent needs for improvement and the most promising directions of future development. Several aspects of mechanical ventilation are introduced, highlighting on one side the importance of interdisciplinary rese...

BACKGROUD AND OBJECTIVES The high frequency oral oscillation therapy (HFOO) is carried through a plastic device which promotes the clearance of pulmonary sputum. This possesses a metallic sphere which, oscillates during the expiration, generating oscillatory positive expiratory pressure. The aim of this study was to verify the performance of the national device of HFOO (Shaker, NCS, São Paulo) ...

Although the number of users of home mechanical ventilation (HMV) is increasing, information regarding the users' perceptions of the impact of HMV on their lives is incomplete. We administered an open-ended questionnaire to 98 (48 male, 50 female) HMV users aged (mean +/- SD) 47.4 +/- 19.5 years with COPD (9%), thoracic restrictive disease (43%), and neuromuscular disease (48%). At the time of ...
