Perhaps you should try some spelling variations:
decrease buried » decrease burden (Expand search), decrease during (Expand search), decrease observed (Expand search)
decrease their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
their decrease » the decrease (Expand search), their disease (Expand search), the decreased (Expand search)
buried object » buried objects (Expand search), based object (Expand search), marked object (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 their decrease akt decrease ) OR ( decrease akt decrease buried object ))~.
