The Spacetimes under consideration are geodesically incomplete and the coupling between the dilaton and gravity diverges at the horizon, so we have a ''singularity without singularity''. Wavefunctions, energy spectrum and electromagnetic radiation are evaluated for charged particles captured by minholes. In some cases the electromagnetic radiation for electrons and protons proves to be comparable with Hawking's radiation for Schwarzschild's miniholes of the same mass. This made to search similar stars in another galaxies. Some of them having apparent superluminal velocities were called micro-quasars, by an analogy with quasars.
Jets are accretion disk descendant.
On other hand, they may be important in excretion of angular moment of accretion disks. Indeed, most part of observed jets are transient and belong to the transient stars. In quiescent these jets are not visible or are very weak. This suggests great number jets under level of detection. This may have implication for future search of jets.
