Perhaps you should try some spelling variations:
"advanced computations and computation program" » "advanced computational and computation program" (Expand search), "advance computational and computation program" (Expand search), "advanced communications and computation program" (Expand search), "advanced computations and computational program" (Expand search), "advanced computations and computational programs" (Expand search), "advanced computations and compensation program" (Expand search), "advanced computation and computation program" (Expand search), "advanced computations in computation program" (Expand search), "advanced computations of computation program" (Expand search)
"advanced oxidation and computer program" » "advanced oxidation _ computer 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 and computer program") OR ("advanced computations and computation program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced oxidation and computer program\") OR (\"advanced computations and computation program\"))*".
• Removing quotes may allow a broader search: (( advanced oxidation and computer program ) OR ( advanced computations and computation program ))*.
