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 ... -
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, ... -

Lifelong Learning: Use of Psychological Factors in the Greek Public Administration
(UIKTEN, 2023)The integration of occupational psychology principles into human resource management is considered appropriate to increase employee productivity and the effectiveness of public sector organizations. In Greece, the use of ... -
Matemática informal y sentido numérico en escolares de priemr ciclo de E. Primaria
(2012)Presentamos un avance de los resultados de una investigación sobre el sentido númerico en alumnos y alumnas de primero y segundo de Educación Primaria de la provincia de Córdoba. Se utilizó un test estandarizado y ... -
Mathematical practical sessions with manipulatives: Trainee teachers’ perceptions of their utility
(Education Association of South Africa, 2019)This study presents the perceptions of trainee teachers regarding the realisation of practical mathematical sessions to expand on the concepts that are taught in primary education using manipulatives. For a 4-month period, ... -
Mathematics in the Spanish press: a case study of the 18th century journal Semanario de Salamanca
(Springer, 2023)Old mathematics books and textbooks have always been sources of relevant information for researchers working on the history of mathematics and mathematics education. However, helpful information about this field can also ... -
MC64-ClustalWP2: A Highly-Parallel Hybrid Strategy to Align Multiple Sequences in Many-Core Architectures
(PLOS, 2014)We have developed the MC64-ClustalWP2 as a new implementation of the Clustal W algorithm, integrating a novel parallelization strategy and significantly increasing the performance when aligning long sequences in architectures ... -
MC64-Cluster: Many-Core CPU Cluster Architecture and Performance Analysis in B-Tree Searches
(2017)The MC64-Cluster computer platform was designed, based on many-core CPU microprocessors: Tile64. MC64-Cluster architecture was outlined in terms of both hardware and software, including commands available to manage jobs ... -
MC64: A web platform to test bioinformatics algorithms in a many-core architecture
(Springer Berlin / Heidelberg, 2011)New analytical methodologies, like the so-called "next-generation sequencing" (NGS), allow the sequencing of full genomes with high speed and reduced price. Yet, such technologies generate huge amounts of data that demand ... -
Measuring attitude towards mathematics using Likert scale surveys: The weighted average
(Public Library Of Science (PLOS), 2020)In the research on mathematics education, numerous Likert-type instruments estimating attitudes toward mathematics are sometimes composed of factors with a high correlation, which can make it difficult to assign the ... -
Mejora de la calidad proteica de dietas maiz-altramuz con aminoácidos sintéticos
(Universidad de Córdoba, Servicio de Publicaciones, 1990)Two experiments involving 696 broiler type chickens from 14 to 28 days of age were carried out to assess the optimun level for lysine, methionine and tryptophan to be added to diets maize-sweet lupin seed meal made ... -
Methodology for the Automatic Inventory of Olive Groves at the Plot and Polygon Level
(MDPI, 2022)The aim of this study was to develop and validate a methodology to carry out olive grove inventories based on open data sources and automatic photogrammetric and satellite image analysis techniques. To do so, tools and ... -
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 ... -
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 ... -
New Bounds for Three Outer-Independent Domination-Related Parameters in Cactus Graphs
(MDPI, 2024)Let G be a nontrivial connected graph. For a set D _ V(G), we define D = V(G) n D. The set D is a total outer-independent dominating set of G if jN(v) \ Dj _ 1 for every vertex v 2 V(G) and D is an independent set of G. ... -
New examples of static spacetimes admitting a unique standard decomposition
(SpringerLink, 2019)In this paper we introduce a new general approach for the study of spacetimes admitting a standard static splitting. This approach allows us to give an alternative proof for the uniqueness of splitting in the spatially ... -
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 ... -
