On Ostrowski type inequalities for Stieltjes integrals with absolutely continuous integrands and integrators of bounded variation

Some Ostrowski type inequalities are given for the Stieltjes integral where the integrand is absolutely continuous while the integrator is of bounded variation. The case when |f′||f′| is convex is explored. Applications for the mid-point rule and a generalised trapezoid type rule are also presented.
