How I could impose some restrictions on levels of factors in Response surface methodology in design of experiment?

As I have 4 factors in an experiment with three levels I need to determine the levels by myself not by alpha method in central composition method. Forexample I need to have x=0.2,0.25,0.33 or...

Why in most od studies regarding nanoparticle transport, the tracer or nanparticle solutions are appiled in large pulses around several porevolumes?

What would be wrong if only small pulse of solution is injected to soil column? The less chemical is used and less contaminated outlet will be collected too. Moreover, if short pulse is applied,...
