The Sierra Nevada’s biological distinction and diversity are almost as legendary as its spectacular peaks and beautiful granite landscapes. The Sierra Nevada is recognized as a zoogeographic region on the basis of the coincidence of species ranges (for example, Udvardy 1969, 1975; Welsh 1994). Udvardy (1969) defined the Sierra Nevada bioregion as bounded by the Great Basin to the north and east...

Providing a minimum of theory, this review focuses on practical aspects analyzing the kinetics nonisothermal crystallization as measured with differential scanning calorimetry (DSC). It is noted that kinetic analysis dominated by approaches based Avrami and Arrhenius equations. Crystallization should not be considered synonymous model, whose applications are subject to very restrictive assumpti...

A class of self-similar sets of entangled quantum states is introduced, for which a recursive definition is provided. These sets, the “Bell gems,” are defined by the subsystem exchange symmetry characteristic of the Bell states. Each Bell gem is shown to be an orthonormal basis of maximally entangled elements.
