Perhaps you should try some spelling variations:
work effectively » more effectively (Expand search), to effectively (Expand search), are effectively (Expand search)
decrease work » decrease or (Expand search), increase work (Expand search), decrease of (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
decrease toc » decrease of (Expand search), decreased to (Expand search), decrease on (Expand search)
toc decrease » to decrease (Expand search), not 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 the decrease and decrease ) OR ( decrease toc decrease work effectively ))~.
