The figure shows a dislocation loop (shown by the solid circle), whose Burgers vector is b (shown by the horizontal arrow inside the dislocation loop). Identify the nature of the dislocation segment at locations p, q and r.
The dash-dot lines show the horizontal and vertical diameters of the loop, and the arrow along the dislocation loop indicates the line vector.
