Talvez deva tentar algumas variações de ortografia:
computer programs » computer program (Expandir a busca)
canker pathogen » canine pathogen (Expandir a busca)
using coupling » running coupling (Expandir a busca), using competing (Expandir a busca), using coupled (Expandir a busca)
pathogen and » pathogens and (Expandir a busca), pathogenic and (Expandir a busca), pathogen in (Expandir a busca)
and computer » _ computer (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( canker pathogen and computer programs ) OR ( using coupling _ python programming ))~.
