Perhaps you should try some spelling variations:
gases transfer » mass transfer, based transfer, gas transfer
we transform » can transform
_ transform » _ transfer, _ transforming
transfer 3 » transfer _, transfer 4, transfer a
agus very » age very
force net » force et, force beth, force de
f gases » _ gases
3 co » _ co, a co, 2 co

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: (( agus very ((we transform) OR (_ transform)) force net ) OR ( guia f gases transfer 3 co ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agus very ((we transform) OR (_ transform)) force net ) or ( guia f gases transfer 3 co ))~".
• Adding a wildcard symbol may retrieve word variants: (( agus very ((we transform) OR (_ transform)) force net ) or ( guia f gases transfer 3 co ))*.
