Perhaps you should try some spelling variations:
"scientific activities" » "scientific activity", "specific activities", "scientific articles"
"scientific societies" » "scientific society", "scientific studies"
"science societies" » "science society", "science science"
"sciences sociales" » "sciences social", "science social"

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: (((("scientific societies") OR ((("science societies") OR ("sciences sociales"))))) OR ("scientific activities")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"scientific societies\") or (((\"science societies\") OR (\"sciences sociales\"))))) or (\"scientific activities\"))".
• Removing quotes may allow a broader search: (((( scientific societies ) or ((( science societies ) OR ( sciences sociales ))))) or ( scientific activities )).
• Adding a wildcard symbol may retrieve word variants: (((("scientific societies") or ((("science societies") OR ("sciences sociales"))))) or ("scientific activities"))*.
