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.
A parallelogram isnât a rhombus, itâs the other way around. Yes, a parallelogram is always a rhombus. No a parallelogram is not always a rhombus. The best way to prove this would be to plot 4 points on a cartesian plain such as A (0,4) B (3,0) C (9,1) D (6,5) find the slope of ab and compare to cd. Then find slope of bc and compare to ad. You find that they are parallel. But to be a rhombus the diagonals have to be perpendicular aka slopes are negative reciprocals of one another. So find slope of bd and ac and compare. Do all this work and will realize itâs a parallelogram and not a rhombus as ac and bd are not negative reciprocals. Cartesian plane*.
