Perhaps you should try some spelling variations:
transform tvdft » transform fft, transform test
mass transfer » cash transfer, basin transfer, mass transport
transfer 3 » transfer _, transfer 4, transfer a
areas two » areas co
guias de » guide de, aguas de, guia do
3 do » _ do, 3 d, 1 do
lamperti » lampert, lamberti, lampietti

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 lamperti transform tvdft a ) OR ( ((guias de) OR (guia de)) mass transfer 3 do ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas two lamperti transform tvdft a ) or ( ((guias de) OR (guia de)) mass transfer 3 do ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas two lamperti transform tvdft a ) or ( ((guias de) OR (guia de)) mass transfer 3 do ))*.
