Phase equilibrium in low-density polyethylene — Normal alkanes systems
The crystalline equilibrium diagrams were obtained for eigh LDPE—n-alkane systems with the cloud point method. A point of view was formulated in which there is a major difference between crystal separation in lowmolecular-weight systems and systems containing flexible macromolecules, and it derives from differences in the essence of the phase transitions that take place in these systems.
This book, which was first published in Russian in 2005, deals with the homogenization of partial differential equations (pdes) of elliptic and parabolic types. The authors study both boundary value problems posed in highly perforated domains or equations with rapidly oscillating coefficients. The standard theory of homogenization (periodic theory, uniformly elliptic oscillating coefficients) is supposed to be already known and the emphasis is put on nonstandard situations leading to multicomponent or nonlocal equations.
