Perhaps you should try some spelling variations:
"supply rates international efforts." » "supply rates international airports.", "supply rates international energy.", "supply rates international airport.", "supply rate international efforts.", "supply states international efforts.", "supply prices international efforts.", "supply water international efforts."
"supply curve integration schemes." » "supply curve irrigation schemes.", "supply curve integration some.", "supply curve integration theories.", "supply care integration schemes.", "supply fare integration schemes.", "supply use integration schemes."

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: "((\"supply rates international efforts.\") OR (\"supply curve integration schemes.\"))~".
• Removing quotes may allow a broader search: (( supply rates international efforts. ) OR ( supply curve integration schemes. ))~.
• Adding a wildcard symbol may retrieve word variants: (("supply rates international efforts.") OR ("supply curve integration schemes."))*.
