Fundamental and practical aspects of therapeutic uses of pulsed electromagnetic fields (PEMFs)
free download

The beneficial therapeutic effects of selected low-energy, time-varying magnetic fields ,
called PEMFs, have been documented with increasing frequency since 1973. Initially, this
form of athermal energy was used mainly as a salvage for patients with long-standing

Bohrens decomposition is extremely useful for investigating scattering by bounded chiral
volumes, but a systematic study of electromagnetic wave propagation characteristics in
chiral media requires knowledge of the infinite medium Greens function, which is, of course

Representation of electromagnetic fields over arbitrary surfaces by a finite and nonredundant number of samples

(EM) field, radiated or scattered by bounded sources, can be accurately represented over a
substantially arbitrary surface by a finite number of samples even when the observation
domain is unbounded. The number of required samples is nonredundant and essentially

The exposure to extremely low frequency electromagnetic field (ELF-MF, frequencies less
than 200-300 Hz) can alter the transcription and translation of genes, influence the cell
proliferation rate and affect enzyme activities. Moreover, the hypothesis that ELFMF

Electromagnetic fields and electromagnetic radiation as non-invasive external stimulants for seeds (selected methods and responses)
