Perhaps you should try some spelling variations:
decrease looping » decrease flooding (Expand search), decrease lodging (Expand search), decrease owing (Expand search)
looping effect » looping effects (Expand search), flooding effect (Expand search), doping effect (Expand search)
decrease that » decrease the (Expand search), decrease at (Expand search), decrees that (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (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)

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

• Removing quotes may allow a broader search: (( decrease _ decrease that decrease ) OR ( decrease akt decrease looping effect ))~.
