Query: New conditional symmetries and exact solutions of reaction-diffusion
  systems with power diffusivities   A wide range of new Q-conditional symmetries for reaction-diffusion systems
with power diffusivities are constructed. The relevant non-Lie ansatze to
reduce the reaction-diffusion systems to ODE systems and examples of exact
solutions are obtained. The relation of the solutions obtained with the
development of spatially inhomogeneous structures is discussed.
