Perhaps you should try some spelling variations:
sampling positions » standing positions (Expand search), making positions (Expand search), sampling location (Expand search)
peptone component » pheromone component (Expand search), ceraone components (Expand search), one component (Expand search)
component control » componente controle (Expand search), compliant control (Expand search), component context (Expand search)
positions python » pitons python (Expand search), positions without (Expand search), positions on (Expand search)
using sampling » using subsampling (Expand search), using saline (Expand search), sinus sampling (Expand search)
coded » codes (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( coded peptone component control program ) OR ( using sampling positions python programming ))~.
