Since you have already posted a similar question on this newsgroup few 
days ago [1] and also you are asking the same ambiguous question on 
MathForum [2], it is hard to tell what kind of help you are seeking? 
(Note that comp.soft-sys.math.mathematica is a newsgroup dedicated to 
the computer algebra system (CAS) Mathematica.) So are you seeking help 

. Mathematica

. the concepts involved in fractional calculus

. some specificities of the function 1/log(x)


. What about the previous replies you got?

. Have you investigated them?

. Did you try anything by yourself?

. ...

At any rate, it would be useful to restate your query in a more precise 
way, to show your work and/or attempts, describe any difficulties faced, 
give relevant background information, ...
