Hello,
I would like to know if it is ok to use the word "upon" in a thesis statemen due that I have always seen "effect on" instead. i.e.
LINEAR SHRINKAGE EFFECTS UPON A SANDY LOAM SAVANNA SOIL PHYSICAL CHARACTERISTICS
LINEAR SHRINKAGE EFFECTS ON A SANDY LOAM SAVANNA SOIL PHYSICAL CHARACTERISTICS
Which one is correct?
Thank you in advance
