Query: Energy losses of Q-balls in Matter, Earth and Detectors   We present a sudy of the interactions of Q-balls with matter, and their
energy losses in the earth, for a large range of velocities. These calculations
are used to computethe fractional geometrical acceptance of underground
detectors. Furthermore we computed the light yield in liquidscintillators, the
ionization in streamer tubes and the Restricted Energy Loss in nuclear track
detectors.
