Perhaps you should try some spelling variations:
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), to decrease (Expand search)
dense methods » dense method (Expand search), defense methods (Expand search), dance methods (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt dense » and dense (Expand search), are dense (Expand search), hot dense (Expand search)
affect » affected (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 _ decrease rate decrease ) OR ( decrease akt dense methods affect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decrease rate decrease ) OR ( decrease akt dense methods affect ))*.
