Perhaps you should try some spelling variations:
"based mathematical geosciencess" » "based mathematical geosciences", "based mathematical geoscience", "based mathematical biosciences"
"based mathematical science" » "based mathematics science", "based mathematical geosciences", "based mathematical finance"
"basic mathematical science" » "basic mathematics science", "basic mathematical geosciences", "basic mathematical finance"
"based mathematical sciences" » "based mathematics sciences", "based mathematical geosciencess", "based mathematical finances"

Try widening your search to All Fields.

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