Perhaps you should try some spelling variations:
friction decrease » fraction decreases (Expand search), action decreases (Expand search), abortion decrease (Expand search)
decrease friction » decrease predation (Expand search), decreased production (Expand search), decreased functional (Expand search)
decrease life » decrease liver (Expand search), increase life (Expand search), decreases liver (Expand search)
life increase » life increases (Expand search), the increase (Expand search), rate increase (Expand search)
of processing » and processing (Expand search), of process (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)

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 life increase of processing ) OR ( decrease friction decrease AND decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease life increase of processing ) OR ( decrease friction decrease and decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease life increase of processing ) OR ( decrease friction decrease and decrease ))*.
