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.
B is not a meso compound as while it does have two stereocenters and has an internal mirror plane that bisects the molecule. Its two opposing stereocenters have different attachments. E is not a meso compound as it does not have two stereocenters and has no internal mirror plane that bisects it.ne such quality is the internal mirror plane. All meso compounds have something called an internal mirror plane. This internal mirror plane is simply a line of symmetry that bisects (cuts in half) the molecule. Each half is a mirror image of the other half.
