Talvez deva tentar algumas variações de ortografia:
sampling density » sampling intensity (Expandir a busca), sampling design (Expandir a busca), stocking density (Expandir a busca)
coding decrease » loading decreased (Expandir a busca), craving decrease (Expandir a busca), toxin decrease (Expandir a busca)
density python » density method (Expandir a busca)
python coding » action coding (Expandir a busca), python code (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( sampling density python coding decrease ) OR ( _ python python python programming ))~.
