A fiber positioner robot for the Gran Telescopio Canarias [PDF]

SPIE Proceedings, 2010
Fiber-fed spectrographs dedicated to observing massive portions of the sky are increasingly being more demanded within the astronomical community. For all the fiber-fed instruments, the primordial and common problem is the positioning of the fiber ends, which must match the position of the objects of a target field on the sky.

Increased PIO2 at exhaustion in hypoxia enhances muscle activation and swiftly relieves fatigue: a placebo or a PIO2 dependent effect?

Frontiers in Physiology, 2016
To determine the level of hypoxia from which muscle activation (MA) is reduced during incremental exercise to exhaustion (IE), and the role played by PIO2 in this process, ten volunteers (21±2 years) performed four IE in severe acute hypoxia (SAH) (PIO2 ...
