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.
The refractive index of zircon is over the limit of the standard gemological refractometer. Spectrum should show a distinct line at 653.5nm, but possibly up to 40 lines. Low type zircon's spectra might have fuzzy lines and not well defined. OTL RI reading, eye visable doubling and spectrum.
