Perhaps you should try some spelling variations:
"appendix mathematics sciences" » "appendices mathematics sciences", "appendix mathematische sciences", "appendix mathmatical sciences", "appendix mathematics science", "appendix mathematic science", "appendix mathematics since"
"appendix mathematical sciences" » "appendix mathematics sciences", "appendix mathematical geosciencess", "appendix mathematical finances"
"appendix mathematical science" » "appendix mathematics science", "appendix mathematical geosciences", "appendix mathematical finance"

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: (((("appendix mathematical sciences") OR ("appendix mathematics sciences"))) OR ("appendix mathematical science"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"appendix mathematical sciences\") OR (\"appendix mathematics sciences\"))) or (\"appendix mathematical science\"))*".
• Removing quotes may allow a broader search: (((( appendix mathematical sciences ) OR ( appendix mathematics sciences ))) or ( appendix mathematical science ))*.
