Hi all,

Could somebody share some examples to differentiate between the use of these words in the context of scientific writing. It would be great if you could kindly list the rules.

Foe example,
1. the information was obtained by /via/through biometric analysis.

2. T cells act by / through/ via secretion of cytokines ( simply stated some chemicals ).

3. Blood samples were collected through / by/ via venepuncture.

Also, is there any difference in thier use in different regions ?

Any information on resources for scientific writing specially grammatical correction is highly appreciated.

Hoping to hear frofm you soon.
