Perhaps you should try some spelling variations:
decrease with » decreases with (Expand search), increase with (Expand search), decrease in (Expand search)
with decrease » with decreased (Expand search), with deceased (Expand search), with increase (Expand search)
decrease when » decrease the (Expand search), decreases wheat (Expand search), decrease their (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (Expand search)
when doing » when moving (Expand search), when being (Expand search), been doing (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 akt decrease with decrease ) OR ( decrease akt decrease when doing ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt decrease with decrease ) OR ( decrease akt decrease when doing ))*.
