Measurements of Catalatic Reaction by an Electronic Manometer

Development of an electronic manometer for intrapleural pressure monitoring.

BACKGROUND Measurement of intrapleural pressure is useful during various pleural procedures. However, a pleural manometer is rarely available. OBJECTIVES The aim of this study was to (1) construct an electronic pleural manometer, (2) assess the accuracy of the measurements done with the new device, (3) calculate the costs of the manometer construction and (4) perform an initial evaluation of ...

An intracardiac manometer: its evaluation and application.

The miniature intracardiac manometer supplied a method for recording artefact-free pressure tracings from the heart and great vessels of man and the intact animal. This instrument has been applied to the procedure of cardiac catheterization. It has also been used to demonstrate that if motion artefacts can be minimized, the central pulse can be recorded with reasonable accuracy by means of mano...

an investigation into translation of cultural concepts by beginner and advance student using think – aloud protocols

this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...

Integrated Digital Manometer for Lumbar Puncture

Comparison measurements of low-pressure between a laser refractometer and ultrasonic manometer.

We have developed a new low-pressure sensor which is based on the measurement of (nitrogen) gas refractivity inside a Fabry-Perot cavity. We compare pressure determinations via this laser refractometer to that of well-established ultrasonic manometers throughout the range 100 Pa to 180 000 Pa. The refractometer demonstrates 10(-6) ⋅ p reproducibility for p > 100 Pa, and this precision outperfor...
