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", "sciences sociales", "science science"

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