decayed changes » decades changes (Expand search), related changes (Expand search), decadal changes (Expand search)
dose processes » noise processes (Expand search), coke processes (Expand search), use processes (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: (( decayed changes decrease dose processes ) OR ( python AND iton python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decayed changes decrease dose processes ) OR ( python and iton python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decayed changes decrease dose processes ) OR ( python and iton python programming ))*.
