Conventionally, ferroelectricity has been observed in materials that are insulating or semiconducting rather than metallic, because conduction electrons in metals screen-out the static internal fields arising from the
dipole moment.
DFT method with Gaussian 09 program with the B3LYP functional and 6-31G(d,p) basis set was used for calculation of physical properties of compounds including stability, Gibbs free energy,
dipole moment in different solvents such as EtOH, MeOH and H2O [15].
The structure of this paper is as follows: the 3D VCKdV equation is derived in Section 2; in Section 3, the exact analytical solution of the equation is obtained; Section 4 is devoted to study atmospheric
dipole blocking by some arbitrary functions and parameters, and a comparison with the previous model and Urals
dipole blocking is made.
Liquid-Metal Pixelated
Dipole. The resonant frequency of a half-wavelength
dipole antenna depends on the electrical length of the
dipole arms.
The goal of this paper is to demonstrate the occurrence of multivortex structures in the superconducting sphere plus magnetic
dipole configuration, especially below and around the transition temperature.
As well as, in the previous article [1], the main attention is devoted to the behavior of the ratio of fields at the tip apex Et and at the surface [E.sub.s], calculated on the basis of the same simple
dipole model.
As is known, an electric
dipole ([micro]) is a vector which is characterized in the direction between two electrical charges, towards +q to -q and module given by the distance d between them [16,20]:
The analogues in the case of the
dipole model of magnetization are: [mathematical expression not reproducible] are the intensities, as well as the induction of the electric and magnetic fields; and; [mathematical expression not reproducible]; [[rho].sub.e] and [[rho].sub.m] are the volume densities of the polarization electric and fictitious magnetic charges; [[rho].sup.st.sub.e] and [[rho].sup.st.sub.m] are the volume densities of external [2] electric and fictitious magnetic charges; [[epsilon].sub.0] [??] [[mu].sub.0], [[epsilon].sub.0] is the electric constant; [mathematical expression not reproducible] are the moments of electric and magnetic
dipoles; [+ or -]q and [+ or -]m are the point electric and fictitious magnetic charges located in the
dipoles at distance l.
Because it repels rather than attracts, we call this region the
Dipole Repeller," study lead author Yehuda Hoffman from the Hebrew University in Jerusalem said in a (http://new.huji.ac.il/en/article/33403) statement .
ISLAMABAD -- As La Nina and Indian Ocean
Dipole (IOD) have subsided, another weather system will enter the country from the west bringing more rain and snowfall from Monday.
Finite element modeling (FEM) was used to study the AE type signals generated from internal
dipole sources in a 600 mm long by 8.5 mm polyvinyl chloride (PVC) rod.
