Talvez deva tentar algumas variações de ortografia:
decrease diffusion » decreases diffusion (Expandir a busca), sucrose diffusion (Expandir a busca)
diffusion problems » diffusion problem (Expandir a busca), diffusion process (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
and decrease » and decreases (Expandir a busca), and decreased (Expandir a busca), and increase (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
code python » codigo python (Expandir a busca), pacote python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code and decrease diffusion problems ) OR ( python code python python programming ))~.
