decrease walking » increase walking (Expand search), decrease during (Expand search), decrease lodging (Expand search)
decreased need » decreased feed (Expand search), decreased level (Expand search), decreased sleep (Expand search)

toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)
need objects » naked objects (Expand search), typed objects (Expand search), field objects (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 toc decrease rate decrease ) OR ( decrease walking decreased need objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease toc decrease rate decrease ) OR ( decrease walking decreased need objects ))*.
