Talvez deva tentar algumas variações de ortografia:
modeling vpython » modeling method (Expandir a busca)
coffee progress » coffee progenies (Expandir a busca), coffee producers (Expandir a busca)
during modeling » using modeling (Expandir a busca), drying modeling (Expandir a busca), drying modelling (Expandir a busca)
vpython python » python python (Expandir a busca), pythons python (Expandir a busca), piton python (Expandir a busca)
imputation in » mutation in (Expandir a busca), imputation of (Expandir a busca), implantation in (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( AND imputation in coffee progress ) OR ( during modeling vpython python programming ))*.
