Perhaps you should try some spelling variations:
decrease further » increase further (Expand search), disease further (Expand search), decrease the (Expand search)
observed objects » observed effects (Expand search), submerged objects (Expand search), buried objects (Expand search)
decrease loss » decrease costs (Expand search), decrease low (Expand search), decrease blood (Expand search)
loss decrease » loss decreases (Expand search), to decrease (Expand search), not decrease (Expand search)
case observed » cases observed (Expand search), are observed (Expand search), course observed (Expand search)
further case » another case (Expand search), further data (Expand search)
decrease on » decrease in (Expand search), decrease of (Expand search), decrease or (Expand search)
on decrease » on decreased (Expand search), of decrease (Expand search), or decrease (Expand search)

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

• Removing quotes may allow a broader search: (( decrease loss decrease on decrease ) OR ( decrease further case observed objects ))~.
