A metal-dielectric interface is usually modeled by a zero-width layer, where dielectric permittivity suffers discontinuity jump. In reality, there narrow transition region, which includes an epsilon-near-zero (ENZ) layer. We show that due to continuous function the dispersion of surface plasmon modified. The energy radiates through ENZ giving rise additional radiative losses. Direct evidence ef...

Quasi-saddles or inherent saddles of the potential energy surface, U , of a liquid are defined as configurations which correspond to absolute minima of the pseudo-potential surface, W = |∇U |, as identified by a multi-dimensional minimisation procedure. The sensitivity of statistical properties of inherent saddles to the convergence criteria of the minimisation procedure is investigated using, ...

We investigate the problem of designing metamaterial structures which operate at very low frequencies. As an example, we consider the case of a DC magnetic cloak, which requires a variable, anisotropic magnetic permeability with both paramagnetic and diamagnetic components. We show that a structure based on superconducting components is the key to diamagnetism at low frequencies, and present a ...

This research was designed to study the effect of bitter almond oil on the healing of open skin wounds in rats. Thirty female adult rats were randomly divided into experimental (n=15) and control (n=15) groups. Under general anesthesia and sterile conditions, one quadrangular (surface area=22 mm) full thickness skin wound was made on the dorsum of each rat. The day of surgery was considered as ...

zirconium dioxide, commonly known as zirconia, is an interesting material and is receiving growing attention due to its excellent mechanical properties. the solid was characterized for surface area measurements, scanningelectron microscopy (sem), energy dispersive x-ray diffractometry (edx) and potentiometric titrations. surface titrations were carried out at the temperature range 303 to 323k i...

one of the difficulties in using absolute altitudes is the separation between the mean open sealevel and geoid. theoretically, geoid is the base level in absolute altitudes, but practically, the mean open sealevel is used as a base level for absolute altitudes. the difference between these two levels is called as the seasurface topography. in this research, it is dealt the mean sea level modeli...
