Electromagnetic field and osteogenesis

Vojnosanitetski pregled, 2007
<zakljucak> Poslednjih 50 godina postignuti su odlicni rezultati primenom elektrobioloske stimulacije osteogeneze. Precizno objasnjenje mehanizma dejstva EMP jos uvek nije dato, sto je jedan od razloga razlicitih pristupa i rezultata lecenja prema iskustvima klinicara i eksperimentnih studija.

Platform Tolerant, High Encoding Capacity Dipole Array-Plate Chipless RFID Tags

IEEE Access, 2019
In this paper, we first carry out an in-depth review of the performance parameters of frequencydomain chipless RFID transponders in terms of their spatial density, spectral capacity, and comprehensive encoding capacity (bit/λ2/GHz) comprising both

The scalar complex potential and the Aharonov-Bohm effect

, 2010
The Aharonov-Bohm effect is traditionally attributed to the effect of the electromagnetic 4-potential $A$, even in regions where both the electric field $\mathbf{E}$ and the magnetic field $\mathbf{B}$ are zero. The AB effect reveals that multiple-valued

The $\nu \nu \gamma$ Amplitude in an External Homogeneous Electromagnetic Field

, 2000
Neutrino-photon interactions in the presence of an external homogeneous constant electromagnetic field are studied. The $\nu \nu \gamma $ amplitude is calculated in an electromagnetic field of the general type, when the two field invariants are nonzero ...

Including virtual photons in strong interactions [PDF]

, 2002
In the perturbative field-theoretical models we investigate the inclusion of the electromagnetic interactions into the purely strong theory that describes hadronic processes. In particular, we study the convention for splitting electromagnetic and strong

Electromagnetic field effects on $\Upsilon$-meson dissociation in PbPb collisions at LHC energies

, 2017
We investigate the effect of the electromagnetic field generated in relativistic heavy-ion collisions on the dissociation of $\Upsilon$ mesons. The electromagnetic field is calculated using a simple model which characterizes the emerging quark-gluon ...
