Geometric methods are one of the most valuable tools for distillation process synthesis and design. The graphical representation of azeotropes, residue curves, distillation regions, and distillation boundaries provide designers with intuition, a wealth of knowledge about the entire composition space

## Abstract A global existence theorem is proved for the LandauβLifshitzβGilbert equations with biquadratic exchange coupling energy acting on the interfaces of a material composed by two ferromagnetic layers separated by a nonmagnetic one. This energy is not convex. The magnetization __M__ satisfi
An automated two-column ion-exchange system was developed to determine the speciation of chromium in water samples. The system is based on retention of cationic Cr(III) species by Chelex-100 resin and anionic Cr(VI) species by an anion resin. The chromium species retained by the resins are eluted se
