Perhaps you should try some spelling variations:
irrigation equipments » irrigation equipment, irrigation requirements, irrigation requirement
equipments based » equipment based, requirements based, equipments valued
array profiling » array processing, microarray profiling
based excision » base excision, based exclusion, based decision
array probing » arrays probing, assay probing, array protein
array string » array strong, arrays strings, array sharing

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: "irrigation equipments based excision ((((array probing) OR (array string))) OR (array profiling))~".
• Adding a wildcard symbol may retrieve word variants: irrigation equipments based excision ((((array probing) OR (array string))) OR (array profiling))*.
