Query: Asymptotically and non-asymptotically flat static black rings in charged
  dilaton gravity   We systematically derive the asymptotically flat five dimensional black rings
in EMd gravity by using the sigma model structure of the dimensionally reduced
field equations. New non-asymptotically flat EMd black ring solutions in five
dimensions are also constructed and their physical properties are analyzed.
