Coronary heart diseases: assessment of risk associated with work exposure to ultralow-frequency magnetic fields.

abstract：:The dielectric behavior of the aqueous solutions of three widely differing macromolecules has been investigated: myoglobin, polyvinylpyrrolidone (PVP), and human serum low-density lipoprotein (LDL). It was not possible to interpret unambiguously the dielectric properties of the PVP solution in terms of water structure...
