β¦ Synopsis
The creep zone boundary has been somewhat arbitrarily defined by Riedel [1,2] as, by equating the equivalent creep strain to the equivalent elastic strain, c"=e o~ ! So the creep zone boundary r (0, t) can be approximated by using the HRR-creep strain field. This leads to

Variational calculus is used to derive an equation for the shape of the cross section of a human red blood cell, the objective being the maximization of the surface area/volume ratio. Comparison to previous work is presented.
This determination was facilitated by the fact that the lattice rotation in [II l] crystals was smltll making the surfrtce anrtlyeis simple. Furthermore, the measurements were made on the thick end of slightly tapered crystals where the Liiders front had terminated.
note on the shape of the red blood cell is revisited, utilizing variational calculus to to find an extremum for the surface area of such a cell, using the volume as a constraint. A fairly significant error in the value of the volume is corrected, and the note concludes with a discussion of measures
