Perhaps you should try some spelling variations:
"radio science theories ii:, mathematics, physics and chemistry" » "radio science theory ii:, mathematics, physics and chemistry", "radio science three ii:, mathematics, physics and chemistry", "radio science theories 1:, mathematics, physics and chemistry", "radio science theories 2:, mathematics, physics and chemistry"
"radio science stories 2:, mathematics, physics and chemistry" » "radio science studies 2:, mathematics, physics and chemistry", "radio science stories _:, mathematics, physics and chemistry", "radio science stories a:, mathematics, physics and chemistry", "radio science stories c:, mathematics, physics and chemistry"
"radio science series 1:, mathematics, physics and chemistry" » "radio science services 1:, mathematics, physics and chemistry", "radio sciences serious 1:, mathematics, physics and chemistry", "radio science studies 1:, mathematics, physics and chemistry", "radio science series 3:, mathematics, physics and chemistry"
"radio science series 2:, mathematics, physics and chemistry" » "radio science services 2:, mathematics, physics and chemistry", "radio sciences serious 2:, mathematics, physics and chemistry", "radio science studies 2:, mathematics, physics and chemistry", "radio science series 3:, mathematics, physics and chemistry"

Try widening your search to All Fields.

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: (((("radio science series 1:, mathematics, physics and chemistry") OR ((("radio science series 2:, mathematics, physics and chemistry") OR ("radio science stories 2:, mathematics, physics and chemistry"))))) OR ("radio science theories ii:, mathematics, physics and chemistry")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"radio science series 1:, mathematics, physics and chemistry\") or (((\"radio science series 2:, mathematics, physics and chemistry\") OR (\"radio science stories 2:, mathematics, physics and chemistry\"))))) or (\"radio science theories ii:, mathematics, physics and chemistry\"))".
• Removing quotes may allow a broader search: (((( radio science series 1:, mathematics, physics and chemistry ) or ((( radio science series 2:, mathematics, physics and chemistry ) OR ( radio science stories 2:, mathematics, physics and chemistry ))))) or ( radio science theories ii:, mathematics, physics and chemistry )).
• Adding a wildcard symbol may retrieve word variants: (((("radio science series 1:, mathematics, physics and chemistry") or ((("radio science series 2:, mathematics, physics and chemistry") OR ("radio science stories 2:, mathematics, physics and chemistry"))))) or ("radio science theories ii:, mathematics, physics and chemistry"))*.
