Perhaps you should try some spelling variations:
during depressed » during depressive (Expand search), during repressive (Expand search), feeling depressed (Expand search)
rotating objects » cutting objects (Expand search), counting objects (Expand search), rotating jets (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)
decrease or » decrease of (Expand search), decrease pro (Expand search), decrease toc (Expand search)
or decrease » of decrease (Expand search), not decrease (Expand search), _ decrease (Expand search)

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease to decrease OR decrease ) OR ( decrease during depressed rotating objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease to decrease or decrease ) OR ( decrease during depressed rotating objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease to decrease or decrease ) OR ( decrease during depressed rotating objects ))*.
