Sentence examples for pumping mechanism from inspiring English sources

The most notable differences between the HeartMate II and the HVAD™ are its smaller size, centrifugal as opposed to axial pumping mechanism, and its lack of mechanical bearings.

Chemist John Pojman of Louisiana State University in Baton Rouge adds that such roving droplets "might be useful as a pumping mechanism for microfluidics, converting chemical energy to mechanical motion in small devices," such as the microfluidic labs-on-a-chip many researchers are developing as diagnostic machines.

A pumping mechanism, driven by enzymes within the red cell, maintains its sodium and potassium concentrations.

However, I am not blind to the controversies — that is, when the pumping mechanism is working properly and I'm not blind for other reasons.

Such structures have the advantage of a protected internal location, but this requires some sort of pumping mechanism to move the external gas-containing medium in and out.

The branchiomeric muscles in cyclostomes are represented by a sheet of constrictors that compresses the gill pouches and helps the pumping mechanism draw water through the pharynx to the gills.

This may imply that early proton release is not essential for a proton-pumping mechanism in general.

ND4 is part of the first respiratory complex, NADH-quinone reductase, which is also involved in electron transport, and it has been suggested to form part of the proton-pumping mechanism (Efremov et al. 2010; Efremov and Sazanov 2011).

However, on the basis of the redox-dependent proton-pumping mechanism proposed for complex I [ 1, 3], the Na+ movement through the enzyme antiporter-like subunits is likely to operate via a different route for which the details are still not known.

A comparison of the primary sequences of pR and bR at first glance seems as to preclude fast H+ release as part of the proton-pumping mechanism of pR due to the absence of residues analogous to Glu194 and Glu 204 of bR.
