Perhaps you should try some spelling variations:
u.s communications » 3.1 communications, les communications, nps communications
developpement la » developpement de, developpement et, developpement du
typologie de » typologie des, typologie der, typologien der
de variation » der variation, die variation, does variation
la afrique » l afrique, la fabrique, en afrique
does u.s » does 4.8
rc le » rh le
c le » c les, 1 le, 3 le

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: "typologie de variation _ does u.s communications ((rc le) OR (c le)) developpement la afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie de variation _ does u.s communications ((rc le) OR (c le)) developpement la afrique.*.
