Perhaps you should try some spelling variations:
terrestrial applications » potential applications, industrial application
industrial applications » industry applications
terrestrial pollution » industrial pollution
terrestrial relations » terrestrial vegetation, industrial relations, terrestrial radio

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: ((((terrestrial pollution) OR (terrestrial relations))) OR (((terrestrial applications) OR (industrial applications)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((terrestrial pollution) OR (terrestrial relations))) or (((terrestrial applications) or (industrial applications))))".
• Adding a wildcard symbol may retrieve word variants: ((((terrestrial pollution) OR (terrestrial relations))) or (((terrestrial applications) or (industrial applications))))*.
