  H. Freeze-up and break-up of river ice (maps 14 & 15)
  Freeze-up lines (isopectics) and break-up lines (isotacs) are shown for the first and fifteenth day of each applicable month during an average season.

• 1970, Swedish Wildlife, Svenska jägareförbundet, page 267:

  [...] easterly migration [probably of the common goldeneye], though now and then interrupted by a cold relapse, is followed by a slower and more gradual northward migration at right angles to the isopectics and thus determined by the temperature and the breaking up of ice further northwards.

  The photostability of chlorine-containing drugs is well-documented. For this reason, the photostability of complexed roflumilast was studied. Figure 5A,B shows the effect of the complexation on the consecutive absorbance signal. [...] Moreover, at around 240 nm, an apparent isopectic point was observed, suggesting a destructive reaction is occurring.
