Talvez deva tentar algumas variações de ortografia:
models functioning » moral functioning (Expandir a busca), soil functioning (Expandir a busca), role functioning (Expandir a busca)
functioning levels » functional levels (Expandir a busca), functional level (Expandir a busca)
levels decrease » levels increase (Expandir a busca), leaves decrease (Expandir a busca), levels increased (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
code models » choke models (Expandir a busca), codon models (Expandir a busca), care models (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code models functioning levels decrease ) OR ( _ python python python programming ))~.
