Perhaps you should try some spelling variations:
"_ convolutional codes using projects" » "_ convolutional codes using project" (Expand search), "_ convolutional codes housing projects" (Expand search), "_ convolutional codes using projections" (Expand search), "_ convolutional code using projects" (Expand search), "_ convolutional nodes using projects" (Expand search), "_ convolutional modes using projects" (Expand search)
"advanced oxidation from python programming" » "advanced oxidation flow python programming" (Expand search), "advanced oxidation free python programming" (Expand search), "advanced oxidation iron python programming" (Expand search), "advanced oxidation from pathogen programming" (Expand search), "advanced oxidation from anthony programming" (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: (("_ convolutional codes using projects") OR ("advanced oxidation from python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ convolutional codes using projects\") OR (\"advanced oxidation from python programming\"))".
• Removing quotes may allow a broader search: (( _ convolutional codes using projects ) OR ( advanced oxidation from python programming )).
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional codes using projects") OR ("advanced oxidation from python programming"))*.
