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!).
Annular Tear Overview. An annular tear â also known as an annular fissure â is a rupture or opening in the annulus fibrosus, the tough outer layer of the cushioning discs that sit between the bones in the spine.When the gel-like substance inside the disc leaks out, it can come in contact with spinal nerves and trigger pain.n annular tear can occur in the cervical spine, creating neck pain, and in the lumbar spine, creating pain or other sensations that may radiate down a single leg or both legs. The pain is often grows worse during lifting or bending motions, sneezing, coughing, sitting and standing.
