The eruptions of Campi Flegrei (Southern Italy), one the most studied and dangerous active volcanic areas world, are fed by mildly potassic alkaline magmas, from shoshonite to trachyte phonotrachyte. Petrological investigations carried out in past decades on rocks provide crucial information for understanding differentiation processes its magmatic system. However, compositional features a palim...

The present article deals with the inter specific competition and intra-specific competition among predator populations of a prey-dependent three component food chain model consisting of two competitive predator sharing one prey species as their food. The behaviour of the system near the biologically feasible equilibria is thoroughly analyzed. Boundedness and dissipativeness of the system are e...

Fair division is a fundamental problem in economic theory and one of the oldest questions faced through the history of human society. The high level scenario is that of several participants having to divide a collection of resources such that everyone is satisfied with their allocation – e.g. two heirs dividing a car, house, and piece of land inherited. The literature on fair division was devel...

adsorbed natural gas has various advantages and is relatively more economical than liquefaction and compression. carbon nanotubes can be introduced as a new candidate for natural gas storage. in this study, adsorption of methane was firstly studied on the as-prepared multi-walled carbon nanotubes, and then chemical and physical treatment of mwcnts was performed to enhance the methane adsorption...

A reaction set of possible mineral weathering reactions is proposed to explain observed cation and silica export for the Emerald Lake watershed, a small Sierra Nevada, California catchment. The reaction set was calculated through a stoichiometric mole-balance method, using a multiyear record of stream flow and snowpack chemical analyses and site-specific mineral compositions. Reaction-set calcu...

The modified NRTL (m-NRTL) model is used to represent the excess Gibbs free energy of aqueous (alcohol + electrolyte) solutions. In this work, the m-NRTL model previously developed for representation of vapor-liquid equilibria for (polymer + salt + water) systems has been extended to represent liquid-liquid equilibria of (alcohol + salt + water) systems. The proposed extension is a modified of ...

We present Thermobar, a new open-source Python3 package for calculating pressures, temperatures, and melt compositions from mineral mineral-melt equilibrium. Thermobar allows users to perform calculations with >100 popular parametrizations involving liquid, olivine-liquid, olivine-spinel, pyroxene only, pyroxene-liquid, two pyroxene, feldspar-liquid, feldspar, amphibole amphibole-liquid, gar...
