Perhaps you should try some spelling variations:
implantation technique » imputation techniques, floatation technique
inhalation technique » floatation technique, imputation techniques, inhaler technique
k implantation » _ implementation
co inhalation » _ inhalation
based co » based code, based no2, based two
based k » based _, based n, based 3d

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: (( learning-based co inhalation technique ) OR ( learning-based k implantation technique ))~.
• Adding a wildcard symbol may retrieve word variants: (( learning-based co inhalation technique ) or ( learning-based k implantation technique ))*.
