MODERN HYDRAULIC-MECHANICAL TRANSMISSIONS IN TRACTORING

Mechanical reliability of AMS hydraulic penile prostheses.

The mechanical reliability of AMS hydraulic penile prostheses implanted in 203 patients from April 1985 to June 1995 were evaluated. AMS Hydroflex prosthesis showed the highest incidence of mechanical failure (18.8%; 6/32 patients) during a mean follow-up period of 94.5 (64-117) months. Mean functioning time of the prostheses until malfunction was 50 (0-100) months. Bilateral fractures at junct...

Mechanical and Control Design Issues in Hydraulic Compliance Control

To be able to define a high-fidelity compliance characteristic to a legged robot using only software, with no change in the hardware, is a feature that greatly enhances the robot’s versatility. We present mechanical and control design aspects that can increase the performance of a hydraulic compliance controller. We also discuss the limitations that the load characteristics can impose to it.

the tragedy of modern man in arthur millers world

what miller wants is a theatre of heightened consciousness. he speaks of two passions in a man, the passion to "feel" and the passion "know". he belives that we can have more of the latter. he says: drama is akin to the other inventions of man in that it ought to help us know more and not merely to spend our feelings. the writing of the crucible shows us that he is trying to give more heightene...

Modern non-invasive mechanical ventilation turns 25.

The history of non-invasive mechanical ventilation goes back more than 100 years, but it was not until 1987 when what we could call "modern" non-invasive mechanical ventilation was developed. The description of Delaubier and Rideau of a patient with Duchenne's disease who had been effectively ventilated through a nasal mask marked the start of a new era in the history of non-invasive mechanical...
