Perhaps you should try some spelling variations:
data communication » data communications
les developpement » le developpement, des developpements, leur developpement
communication et » communication 3, communication 1, communication 2
developpement en » developpement et, developpement des, developpement de
de variation » der variation, die variation, does variation
typology de » typology _, typology 6, typology a
im does » im doner, jam does
m does » 2 does, 4 does, 1 does

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "typology de variation ((im does) OR (m does)) data communication et les developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology de variation ((im does) OR (m does)) data communication et les developpement en afrique.*.
