transformed de » transformed _, transformed 1, transformed a
set transport » sea transport, heat transport, salt transport
policy across » policy actors, policies across, policy actions
wall flow » mail flow
agua a » agua la, agua e, agua 2
a set » _ set
acao » cacao, macao, cao

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( agua a set transport policy across ) OR ( agua wall flow transformed de acao ))~.
• Adding a wildcard symbol may retrieve word variants: (( agua a set transport policy across ) or ( agua wall flow transformed de acao ))*.
