Perhaps you should try some spelling variations:
"advanced computation in computer program" » "advanced computations in computer program" (Expand search), "advanced computational in computer program" (Expand search), "advance computational in computer program" (Expand search), "advanced computation and computer program" (Expand search), "advanced computation of computer program" (Expand search), "advanced imputation in computer program" (Expand search), "advanced computation _ computer program" (Expand search)
"advanced oxidation in computational program" » "advanced oxidation and computational program" (Expand search), "advanced oxidation _ computational program" (Expand search), "advanced oxidation of computational program" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("advanced oxidation in computational program") OR ("advanced computation in computer program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced oxidation in computational program\") OR (\"advanced computation in computer program\"))".
• Removing quotes may allow a broader search: (( advanced oxidation in computational program ) OR ( advanced computation in computer program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced oxidation in computational program") OR ("advanced computation in computer program"))*.
