Perhaps you should try some spelling variations:
"a regional consequences" » "a emotional consequences", "a legal consequences", "a global consequences"
"a medical consequences" » "a clinical consequences", "a physical consequences", "a social consequences"
"its regional convergence" » "its global convergence", "its region convergence"

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: (((("a regional consequences") OR ("a medical consequences"))) OR ("its regional convergence"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"a regional consequences\") OR (\"a medical consequences\"))) or (\"its regional convergence\"))*".
• Removing quotes may allow a broader search: (((( a regional consequences ) OR ( a medical consequences ))) or ( its regional convergence ))*.
