Contrary to an important explanatory principle of traditional dialectology, according to which (political) borders impede communication and thereby lead to the emergence of linguistic differences, I will argue that putative or factual linguistic differences are used for the social construction of (political) borders, and that existing (political) borders are symbolically reinforced by attractin...

I discuss the structure of current-induced bottom baryon to charm baryon transitions, and the structure of pion and photon transitions between heavy charm or bottom baryons in the Heavy Quark Symmetry limit as mQ → ∞. The emphasis is on the structural similarity of the Heavy Quark Symmetry predictions for the three types of transitions. The discussion involves the ground state s-wave heavy bary...

The characteristics and mechanisms of Pb sorption by biochars produced from sugarcane bagasse at 250, 400, 500, and 600 °C were examined. The Pb sorption isotherms, kinetics and desorption were investigated. All biochars were effective in Pb sorption and were well described by Langmuir isotherm model and pseudo-second-order kinetic model. The maximum sorption capacity decreased from 21 to 6.1 m...

SU(N) Yang-Mills theories, which are expected to describe the strong interaction in the case N = 3, are one of the most studied models in theoretical physics. While their asymptotic UV behavior is well under control thanks to asymptotic freedom, the need of non-perturbative techniques to describe the IR behavior has rapidly appeared to be mandatory. The reasons of this non-perturbativity of the...
