NIntegrate::slwcon: 
        Numerical integration converging too
          slowly; suspect one of the
          following: singularity, oscillatory
          integrand, or insufficient
          WorkingPrecision.

     NIntegrate::ncvb: 
        NIntegrate failed to converge to
          prescribed accuracy after 7
          recursive bisections in x near x = 
         0.0245437.
