Talvez deva tentar algumas variações de ortografia:
containing program » conditioning program (Expandir a busca), containing piroxicam (Expandir a busca), containing proximal (Expandir a busca)
boron complexes » iron complexes (Expandir a busca), ion complexes (Expandir a busca), bound complexes (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
using python » usando python (Expandir a busca), in python (Expandir a busca)
using using » housing using (Expandir a busca), aging using (Expandir a busca), ring using (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code boron complexes containing program ) OR ( using using python python programming ))~.
