Simlifying Sqrt[x^2] type args.

Hello,

I am curious if there is a way to do symbolics in mathematica
where objects like 

Sqrt[k^2 r^2 Sin[theta]^2] 

are set to

k r Sin[theta]

..

I am doing a long calculation and objects as the above
occur in many places, usualy as arguments to BesselJ 
functions, and it would be nice to have mathematica 
resolve these for me, it would even be nicer if it could
be done globaly for all calculations withing the notbook.

thanks,

-Jaime
