Talvez deva tentar algumas variações de ortografia:
they processes » the processes (Expandir a busca), theory processes (Expandir a busca), these processes (Expandir a busca)
diseases they » diseases the (Expandir a busca), diseases their (Expandir a busca), diseases that (Expandir a busca)
python redes » python regius (Expandir a busca), python code (Expandir a busca)
piton python » pitons python (Expandir a busca), in python (Expandir a busca), with python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease of diseases they processes ) OR ( python redes piton python programming ))~.
