Talvez deva tentar algumas variações de ortografia:
functional programs » functional problems (Expandir a busca), functional programming (Expandir a busca), educational programs (Expandir a busca)
method functional » method fractional (Expandir a busca), metodo functional (Expandir a busca), method function (Expandir a busca)
improve processes » improve process (Expandir a busca), improving processes (Expandir a busca), improvement processes (Expandir a busca)
decrease improve » decrease income (Expandir a busca), decrease pro (Expandir a busca), decrease sucrose (Expandir a busca)
decrease of » decrease in (Expandir a busca)
of decrease » or decrease (Expandir a busca), not decrease (Expandir a busca), to decrease (Expandir a busca)
python apac » python capaz (Expandir a busca), python api (Expandir a busca)
apac method » hplc method (Expandir a busca), abc method (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease of decrease improve processes ) OR ( python apac method functional programs ))~.
