In this paper the motion of electron in a miniband of a semiconductor superlattice (SSL) under the influence of external electric and magnetic fields is investigated. The electric field is applied in a direction perpendicular to the layers of the semiconductor superlattice, and the magnetic field is applied in different direction Numerical calculations show conditions led to the possibility of ...
The produced electric and magnetic fields due to lightning strikes to mountainous ground are determined in this paper. For the sake of simplicity a cone-shaped ground with finite conductivity is assumed to represent a natural nonflat ground. By this assumption, we deal with an axillary symmetrical structure so we use the cylindrical 2D-FDTD to save the simulation memory and time, dramatically. ...
Objective- Although the promotional effects on bone healing of pulsed electromagnetic fields (PEMF)have been well demonstrated, the effects of static magnetic fields (SMF) remained unclear. In this study,effects of SMFs on clinical and biomechanical aspects of bone healing using a canine unstable osteotomygap model were investigated .Design- Prospective descriptive trial.Animals- Fifteen mongre...
Magnetic nanomaterials are making significant impact on improving the quality of human health that is tangible from a wide range of applications in various fields of medicine and biology. In recent years, nanoparticles successfully demonstrated outstanding applications due to having excellent magnetic properties of the iron oxide nanoparticles-based counterparts. Zero-valent iron nanoparticles ...
