Perhaps you should try some spelling variations:
"teaching computational using diffusion program" » "using computational using diffusion program" (Expand search), "teaching educational using diffusion program" (Expand search), "applying computational using diffusion program" (Expand search), "teaching computation using diffusion program" (Expand search), "teaching computations using diffusion program" (Expand search), "teaching computacional usinas diffusion program" (Expand search), "teaching computational using diffusion problem" (Expand search), "teaching computational using diffusion problems" (Expand search), "teaching computational using diffusion process" (Expand search)
"using modis python python programming" » "using modis pythons python programming" (Expand search), "using modis piton python programming" (Expand search), "using modis pitons python programming" (Expand search), "using codigos python python programming" (Expand search), "using codigo python python programming" (Expand search), "using modulo python python programming" (Expand search), "using mobile python python programming" (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"teaching computational using diffusion program\") OR (\"using modis python python programming\"))~".
• Removing quotes may allow a broader search: (( teaching computational using diffusion program ) OR ( using modis python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("teaching computational using diffusion program") OR ("using modis python python programming"))*.
