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

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: "(( learning-based no2 inhalation technique ) OR ( learning-based n floatation technique ))~".
• Adding a wildcard symbol may retrieve word variants: (( learning-based no2 inhalation technique ) OR ( learning-based n floatation technique ))*.
