Patient discussion about second

Q. second wind My cousin is an experienced aerobic for nearly 2 years. She does vigorous exercises. How a ''second wind'' affects her and what is it?

A. The term ‘second wind is mostly known to the people who are related to the fitness. No matter how fit you are, the first few minutes into vigorous exercise you'll feel out of breath, and your muscles may ache. Your body isn't able to transport oxygen to the active muscles quickly enough. As a result, your muscles burn carbohydrates an aerobically, causing an increase in lactic acid production. Gradually, your body makes the transition to aerobic metabolism and begins to burn nutrients (carbohydrates and fats) aerobically. This shift over to aerobic metabolism coincides with your getting ''back in stride'' (a.k.a. the ''second wind''). The more you train and the more fit you become, the sooner you will get your ''breath'' back and reach an aerobic steady state that you can maintain for a relatively extended duration.

Arc Second reported that the accuracy of its system depends largely on the accuracy of the means used to scale it.
That translates into 8 arc seconds for flatness, not very accurate for today's ever-tightening tolerances," says Hamar.
Ifadaptive telescopes with electrically deformable mirrors and artificial guide stars can work together to overcome the problems of atmospheric turbulence, resolution could improve to 1/10 of an arc second, Thompson says, the same resolution promised by the Hubble Space Telescope scheduled for launch in 1988.
Mounted to the gear reducer output shaft, they provide 0.27 arc second resolution -- an improvement over the 14 arc second resolution of the incremental encoders Toms previously used.
It shows hundreds of luminous blue stars packed into a region less than 5 arc seconds (4 light-years) across.
McCarthy does not rule out the possibility that VB 8B is not there at all, but says it is more likely that the object has moved to about 1/2 arc second from van Biesbroeck 8.

It holds that the angular resolution of images formed on photographic plates or electronic detectors should be typically about 1 arc second. For a large telescope costing millions of dollars, such an outcome is disappointing; a 6-inch backyard telescope can also achieve 1-arc-second resolution!
