    "abstract": "Starting from relativistic quantum field theories, describing interacting\nnucleons and pions coupled to the dynamical electromagnetic field, the pion\ndegrees of freedom are eliminated by means of functional integration. Apart\nfrom taking into account some operators perturbatively in $e$, e.g. the vacuum\npolarization, this procedure is exact, giving effective theories for nucleons\nand photons. The subsequent nonrelativistic reduction yields the corresponding\nnonrelativistic quantum field theory. The latter is unique, irrespective of the\nprecize form of the original nucleon-pion interaction. Nucleonic potentials and\nelectromagnetic interactions are mutually consistent. Local gauge invariance is\nsatisfied at any stage of the formal developments.",
