This investigation was carried out within the Parane sedimentary basin and neighbourhood in Brazil and involved the sampling of different water types with the purpose of evaluating its quality. Several methods were utilized ...

We study the N-component (2+1)-dimensional Gross-Neveu model bounded between two parallel planes separated by a distance L at finite temperature (T). We obtain a closed expression for the large-N effective coupling constant ...

En el Perú, la disponibilidad de información sobre indicadores macroeconómicos es a nivel agregado nacional, la información a nivel subnacional es escasa y muchas veces rezagada. Este trabajo presenta un modelo econométrico ...

This paper analyses the process of regional economic convergence in Ecuador from 2007 to 2014, using parametric and non-parametric models. Applying a broad range of methods allows deriving complex empirical findings about ...

We study the N-component (2+1)-dimensional Gross–Neveu model bounded between two parallel planes separated by a distance L at finite temperature T. From the four-point function, we obtain a closed expression for the large-N ...

We analyze the effect of the antineutrino mass over the β −-decay rates calculated within the scheme of the Gross Theory of Beta Decay (GTBD). We give a non null value to the mass of the antineutrino participating in β ...
