Perhaps you should try some spelling variations:
integration theories » integration theorems, integrationstheorie 2, integration theory
integration efforts » international efforts, conservation efforts
case integration » care integration, scale integration, based integration
supply grid » supply crowd, supply great, support grid
supply case » supply cost, supply chain, supply curve

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 grid integration efforts. ) OR ( supply case integration theories. ))~".
• Adding a wildcard symbol may retrieve word variants: (( supply grid integration efforts. ) OR ( supply case integration theories. ))*.
