Perhaps you should try some spelling variations:
decreases during » decrease during (Expand search), increases during (Expand search), decreases lung (Expand search)
owing decreases » logging decreases (Expand search), ageing decreases (Expand search), taping decreases (Expand search)
decrease owing » decrease lodging (Expand search), decrease during (Expand search), decrease in (Expand search)
during object » using object (Expand search), moving object (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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease AND decrease on decrease ) OR ( decrease owing decreases during object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND decrease on decrease ) OR ( decrease owing decreases during object ))*.
