Perhaps you should try some spelling variations:
decrease processes » disease processes (Expand search), decay processes (Expand search)
decrease decrease » decrease release (Expand search), disease decreases (Expand search), decrease sucrose (Expand search)
integral programa » integrity program (Expand search)
perron integral » perron integrable (Expand search), error integral (Expand search), periodo integral (Expand search)
python using » python usando (Expand search), python coding (Expand search), action using (Expand search)
using perron » using error (Expand search), using personal (Expand search), using ferrous (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease NOT decrease decrease processes ) OR ( python using perron integral programa ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease NOT decrease decrease processes ) OR ( python using perron integral programa ))*.
