Query: Domain Walls and the Creation of Strings   The phenomenon of creation of strings, occurring when particles pass through
a domain wall and related to the Hanany-Witten effect via dualities, is
discussed in ten and nine dimensions. We consider both the particle actions in
massive backgrounds as well as the 1/4-supersymmetric particle-string-domain
wall supergravity solutions and discuss their physical interpretation. In 10D
we discuss the D0-F1-D8 system in massive IIA theory while in 9D the
SL(2,R)-generalisation is constructed. It consists of (p,q)-particles,
(r,s)-strings and the double domain wall solution of the three different 9D
gauged supergravities where a subgroup of SL(2,R) is gauged.
