Compactness versus interior-to-edge ratio; two approaches for habitat's ranking.

In landscape ecology spatial descriptors (or indices) can be used to characterize habitats. Some of these descriptors can be used for habitat's ranking; this ranking is very important for conservation purposes. We would like to show that two traditional descriptors, namely the compactness and interior-to-edge ratio can give contradictory results. Being the second one is a more relevant descriptor, we would like to propose to avoid the further use the compactness in habitat's ranking.

Stability limits in binary fluids mixtures.

The stability limits in binary fluid mixtures are investigated on the basis of the global phase diagram approach employing a model for the attracting hard-sphere fluid. In addition to the diffusion spinodals the mechanical spinodals are included. As a result one finds topologically different types of the diffusion spinodals while only one shape exists for the mechanical spinodals which are present in the region of liquid-vapor equilibria only. The diffusion spinodals represent the underlying properties of the phase behavior. The types of stable phase behavior therefore resemble that of the spinodal behavior. The different shapes of the spinodals can be important for nonequilibrium processes in nature and technology.
