  Absorption problems of run-and-tumble particles, described by the
telegrapher's equation, are analyzed in one space dimension considering
partially reflecting boundaries. Exact expressions for the probability
distribution function in the Laplace domain and for the mean time to absorption
are given, discussing some interesting limits (Brownian and wave limit, large
volume limit) and different case studies (semi-infinite segment, equal and
symmetric boundaries, totally/partially reflecting boundaries).
