•In consequence of these features the axial pump has a distinct advantage for variable-speed services.
•The spark was preferred to the arc on account of (or because of, or owing to) its ease of control.
•As a consequence (or result) of its change in speed, a light ray passing obliquely from a vacuum to a material medium is refracted.
•The body loses heat by radiation.
•The hole density fluctuation is small by virtue of the condition ((())" 1).
