Notes and Correspondence: Melting Point of Sodium Nitrate

Melting of sodium clusters

Thermal stability properties and the melting-like transition of NaN , N = 13-147, clusters are studied through microcanonical molecular dynamics simulations. The metallic bonding in the sodium clusters is mimicked by a many-body Gupta potential based on the second moment approximation of a tight-binding Hamiltonian. The characteristics of the solid-to-liquid transition in the sodium clusters ar...

JASs Correspondence & Notes

The knowledge of the evolution of the human genome is strictly dependent on the availability of appropriate genetic markers and their relative coverage of genetic variation which refine the phylogenetic reconstruction. While autosomal markers are particularly valuable for recognizing correspondence between genetic and geographic distances, markers on mitochondrial DNA (mtDNA) or Non Recombining...

JASs Correspondence & Notes

A lot of ink has been spilt in Paleoanthro-pology in discussing whether or not Neander-thals possessed complex language (which means " human language in the modern sense " , quoting Arbib, 2005, p. 21, that is, a representational and communicative system with hierarchical and recursive structure), given their phylogenetic closeness to modern humans. Recently, Frayer et al. (2010) (this journal,...

Investigation of Thermodynamic Properties of Heavy Metals from Melting and Critical Point Properties

A statistical mechanical based equation of state has been employed to calculate the liquid density of lead, mercury, bismuth and lead-bismuth and lead-lithium eutectic alloys.The equation is basically that of Song, Mason and Ihm [Ihm G, Song Y, Mason EA. J. Chem. Phys.1991; 94: 3839] which is modified by Ghatee and Boushehri. Three temperature dependent parameters are required to use this e...
