gases transfer » mass transfer, based transfer, gas transfer
transfer 3 » transfer _, transfer 4, transfer a
areas own » areas can
fft 4 » fat 4, fft _, fit 4
aft 4 » act 4, art 4
3 ao » 3 a, 3 co, 3 do

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: (( areas own leadership transform ((fft 4) OR (aft 4)) ) OR ( guias _ gases transfer 3 ao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas own leadership transform ((fft 4) OR (aft 4)) ) or ( guias _ gases transfer 3 ao ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas own leadership transform ((fft 4) OR (aft 4)) ) or ( guias _ gases transfer 3 ao ))*.
