I review recent estimates of the non-perturbative hadronic vacuum polarization contributions. Since these at present can only be evaluated in terms of experimental data of limited precision, the related uncertainties pose a serious limitation in our ability to make precise predictions. Besides e+e-

The authors' magnetic field density functional theory is extended to include electron spin-dependent interactions. Coupling the new theory with traditional spin density functional theory in the local limit yields a linear differential equation for the net spin density. The coefficients in the equat
The density dependence of J13c-n in 13CH4 has been accurately measured in a methane sample containing thenatural amotmt of ~3CH4. A linear increase of J~3c-n with increasing density has been found. The total variation over a density interval from 0-575 amagat is 0.24 Hz.
