areas two » areas co
guias de » guia de, guide de, aguas de
de mass » de masse, de mais, de masa
atd a » add a, aid a, ahd a
a dot » _ dot
a do » _ do, a d, a co
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 atd a ) OR ( guias de mass transfer ((a do) OR (a dot)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas two lamperti transform atd a ) or ( guias de mass transfer ((a do) OR (a dot)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas two lamperti transform atd a ) or ( guias de mass transfer ((a do) OR (a dot)) ))*.
