On complete trapped submanifolds in globally hyperbolic spacetimes
(IOP Publishing, 2023)
The aim of this manuscript is to obtain rigidity and non-existence results for parabolic spacelike submanifolds with causal mean curvature vector field in orthogonally splitted spacetimes, and in particular, in globally ...
La formación agropecuaria en el nivel universitario en Argentina: su vinculación con los cambios en el sector tecnológico productivo en el marco del proceso de acreditación
(Universidad de Córdoba, UCOPress, 2023)
La agronomía es una ciencia que tiene como objetivo mejorar la calidad de las técnicas de producción, así como de los procesos de transformación de alimentos y productos agrícolas. La ingeniería agronómica ayuda a mejorar ...
Actitudes hacia las matemáticas en estudiantes de educación media en Colombia
(Universidad de Córdoba, UCOPress, 2023)
Socialmente, tanto la enseñanza como el aprendizaje y procesos de evaluación en matemáticas han sido relacionados directa y exclusivamente con un carácter selectivo y racional (Ávila Contreras y Díaz Moreno, 2019), sin ...
Layer-averaged approximation of Navier–Stokes system with complex rheologies
(EDP Sciences, 2023)
In this work, we present a family of layer-averaged models for the Navier–Stokes equations. For its derivation, we consider a layerwise linear vertical profile for the horizontal velocity component. As a particular case, ...
Multilayer models for hydrostatic Herschel-Bulkley viscoplastic flows
(Elsevier, 2023)
Starting from Navier-Stokes’ equation we derive two shallow water multilayer models for yield stress fluids, depending on the asymptotic analysis. One of them takes into account the normal stress contributions, making ...
Non-hydrostatic layer-averaged approximation of Euler system with enhanced dispersion properties
(Springer, 2023)
A new family of non-hydrostatic layer-averaged models for the non-stationary Euler equations is presented in this work, with improved dispersion relations. They are a generalisation of the layer-averaged models introduced ...
A general vertical decomposition of Euler equations: Multilayer-moment models
(Elsevier, 2023)
In this work, we present a general framework for vertical discretizations of Euler equations. It generalizes the usual moment and multilayer models and allows to obtain a family of multilayer-moment models. It considers a ...
Multilayer Shallow Model for Dry Granular Flows with a Weakly Non-hydrostatic Pressure
(Springer, 2023)
The multilayer model proposed in this paper is a generalization of the multilayer non-
hydrostatic model for shallow granular flows (Fernández-Nieto et al in Commun Math Sci
16(5):1169–1202, 2018. https://doi.org/10.43 ...
Language acculturation among the children of immigrants in Spain at the end of the prodigious decade of immigration
(Editorial Universidad de Alcalá, 2023)
In Spain, few studies have analyzed how children of immigrants
combine the acquisition of Spanish with the maintenance/acquisi-
tion of heritage languages. This paper moves into that direction by
exploiting data from a ...
