Perhaps you should try some spelling variations:
layered transform » lamperti transform, wavelet transform, leaders transform
gas transport » mass transport, bus transport, car transport
two layered » two layer
transport 2 » transport _, transport a, transport 4
areas two » areas co
guias de » guia de, guide de, aguas de
de gas » de gaos, die gas, de gaz
set a » set _
get a » get _
2 co » _ co, a co, 2 c

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 two layered transform ((set a) OR (get a)) ) OR ( guias de gas transport 2 co ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas two layered transform ((set a) OR (get a)) ) or ( guias de gas transport 2 co ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas two layered transform ((set a) OR (get a)) ) or ( guias de gas transport 2 co ))*.
