Talvez deva tentar algumas variações de ortografia:
efficient solution » efficient solutions (Expandir a busca), efficient production (Expandir a busca), efficient computation (Expandir a busca)
fetal processes » mental processes (Expandir a busca), legal processes (Expandir a busca), final processes (Expandir a busca)
decrease fetal » decrease fear (Expandir a busca), decrease renal (Expandir a busca), decrease total (Expandir a busca)
decrease with » decreases with (Expandir a busca), increase with (Expandir a busca), decrease in (Expandir a busca)
with decrease » with decreased (Expandir a busca), with decreases (Expandir a busca), with deceased (Expandir a busca)
non efficient » on efficient (Expandir a busca), an efficient (Expandir a busca), in efficient (Expandir a busca)
script non » script of (Expandir a busca), script in (Expandir a busca), scripts on (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease with decrease fetal processes ) OR ( python script non efficient solution ))~.
