1 You have signs of infection, such as: 2  Increased pain, swelling, warmth, or redness around the bite. 3  Red streaks leading from the bite. 4  Pus draining from the bite.  A fever.
A negative index of refraction due to three-dimensional chirality is demonstrated for abilayered metamaterial based on pairs of mutually twisted planar metal patterns in parallel planes, which alsoshows negative electric and magnetic responses and exceptionally strong optical activity and circular dichro-ism.
With a refractive index of 2.65-2.69, moissanite exhibits more brilliance than diamond. And thanks to a dispersion that has 2.4 times the fire of diamond, moissanite bends light into mesmerizing rainbow flashes of fireâ¦ more than twice as much as diamond, ruby, emerald, or sapphire.
