The dilute Fermi gas at unitarity is scale invariant and its bulk viscosity vanishes. We compute, in the high temperature limit, the leading contribution to the bulk viscosity when the scattering length is not infinite. A measure of scale breaking is provided by the ratio (P-2πħ/3ε)/P, where P is the pressure and E is the energy density. At high temperature this ratio scales as zλ/a, where z is...

A singularity on the negative fugacity axis of the hard-square lattice gas is investigated in terms of numerical diagonalization of transfer matrices. The location of the singular point z− c and the critical exponent ν are accurately determined by the phenomenological renormalization technique as −0.11933888188(1) and 0.416667(1), respectively. It is also found that the central charge c and the...

An overview is presented of the possibilities of applying multimedia compartmental evaluative models, and in particular the fugacity approach, to predict the environmental distribution and fate of organic chemicals. The use of this predictive approach for the evaluation of exposure to pollutants in the aquatic system is described, with reference to different environments or discharge patterns (...

Many statistical mechanics problems can be framed in terms of random curves; we consider a class of three-dimensional loop models that are prototypes for such ensembles. The models show transitions between phases with infinite loops and short-loop phases. We map them to CP(n-1) sigma models, where n is the loop fugacity. Using Monte Carlo simulations, we find continuous transitions for n=1, 2, ...

The Arvaneh volcanic cone at eastern part of the Sahand volcanic complex is located on SW of Bostanabad city. This cone having lava composition as dacite, dacitic andesite and rhyodacite, is formed eletted to young volcanic activity of the Sahand volcanism. Having various colours and textures form dominant composition of the lavas in the Petrographycally phenocrysts are plagioclase+hornblende+b...

Jebale-Barez plutonic complex is composed of granitoid intrusive bodies and is located in the east- northeast Jiroft, southeastern Kerman Province. The plutonic complex is composed of granodiorite, quartzdiorite and granite - alkaligranite. The Plutonic rocks are mainly composed of plagioclase, alkali-feldspar, biotite, amphibole and quartz. Based on microprobe analysis, plagioclase composition...

The Mishu garnitoidic complex is cropped out in NW of Mishu mountains, in southwest of Marand, northwest Iran (East Azarbaidjan) which is intruded into Kahar Formation. Based on petrographic studies, this pluton is composed of intermediate rocks including granodiorite, quartzmonzodiorite and diorite. Plutonic rocks are mainly composed of quartz, plagioclase, orthoclase, biotite, amphibole and p...

Self avoiding random surfaces on a cubic lattice are studied by extensive Monte Carlo sampling The surfaces have empty boundary and the topology of a sphere An oct tree data structure allows to obtain good statistics for surfaces whose plaquette number is almost an order of magnitude greater than in previous investigations Maximum likelihood determinations of the critical plaquette fugacity and...

Strangeness production in heavy ion collisions at relativistic energies provides one of the key information about the reaction mechanism and could indicate the onset of new phenomena. The attempts to describe the measured particle ratios including strange hadrons at AGS and SPS and recently also at RHIC using a strangeness fugacity are very successful [1, 2, 3, 4, 5]. However, the usual grand-c...
