Talvez debería tentar con algunhas variantes ortográficas:
surface diffusion » state diffusion
information gis » information gain, information gaps, information grid
array string » array strong, arrays strings, array sharing
gis surface » gas surface, gibbs surface, axis surface
array using » arrays using

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: information gis surface diffusion ((((array using) OR (array string))) OR (array format))~.
• Adding a wildcard symbol may retrieve word variants: information gis surface diffusion ((((array using) or (array string))) or (array format))*.
