Exercise-induced bronchospasm (EIB) happens when the airways in your lungs narrow when you exercise. This makes it hard to breathe. If you have EIB, it may be hard to exercise for more than 30 minutes at a time. EIB also is called exercise-induced bronchoconstriction. It is the same thing as exercise-induced asthma.
When traces on a circuit board need to connect to another layer, they typically end up on a pad and then through a via on that pad go to connect to another layer. An annular ring is the area on the pad that surrounds the via. An Annular Ring Width is the (diameter of the pad-diameter of the hole) / 2. (Tangency is the default option, and the DFM will check for 5 Mils minimum annular ring width). (NOTE: accepting Breakouts is typically NOT recommended!).
Introduction. Granuloma annulare is a long-lasting rash that looks like a ring of small red or skin-coloured bumps. The rash usually appears over the backs of your forearms, hands or feet.
