The Other Side as a Rule Rather than an Exception
2015
Abstract Currently, intercultural and heterogeneous realities set the tone in 21st literary education. Therefore, the role of multicultural children's literature plays an essential role in order to reflect this intercultural diversity in Spanish classrooms. In this regard, The Other Side (2001) portrays an African American experience where interaction, communication and negotiation become crucial aspects for their protagonists. In this way, this picture book can be used not only to teach English as a foreign language in primary school, but also to show values like respect, tolerance and partnership.
Measurement of the top quark charge in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector
2013
A measurement of the top quark electric charge is carried out in the ATLAS experiment at the Large Hadron Collider using 2.05 fb[superscript −1] of data at a centre-of-mass energy of 7 TeV. In units of the elementary electric charge, the top quark charge is determined to be 0.64 ± 0.02 (stat.) ± 0.08 (syst.) from the charges of the top quark decay products in single lepton t[¯ over t] candidate events. This excludes models that propose a heavy quark of electric charge −4/3, instead of the Standard Model top quark, with a significance of more than 8σ.
Polyphenols Epigallocatechin Gallate and Resveratrol, and Polyphenol-Functionalized Nanoparticles Prevent Enterovirus Infection through Clustering an…
2021
To efficiently lower virus infectivity and combat virus epidemics or pandemics, it is important to discover broadly acting antivirals. Here, we investigated two naturally occurring polyphenols, Epigallocatechin gallate (EGCG) and Resveratrol (RES), and polyphenol-functionalized nanoparticles for their antiviral efficacy. Concentrations in the low micromolar range permanently inhibited the infectivity of high doses of enteroviruses (107 PFU/mL). Sucrose gradient separation of radiolabeled viruses, dynamic light scattering, transmission electron microscopic imaging and an in-house developed real-time fluorescence assay revealed that polyphenols prevented infection mainly through clustering of…
The Need to Approach the Management of the Tourist Destination by the Central and Local Public Authorities in Romania
2017
Abstract In the medium and long term, priorities in the development of tourism aim to develop a complex tourist offer, making the most of the natural and anthropogenic resources existing in connection with the preservation of the environment and the heritage. On the long run, it will contribute to raising the living standards of the population, especially social categories with lower chances of reintegration into the labour market (people made redundant in industry, elderly people etc.). Implementation of the strategy at regional level must be achieved through an active partnership between Romanian public authorities, economic agents and private investors, with the involvement of the federa…
Satisfacción de la mujer con los cuidados de salud recibidos durante el parto prematuro: adaptación y validación al castellano de la Preterm Birth Ex…
2020
Introducción Todas las mujeres tienen derecho a recibir una atención sanitaria de excelencia. Conocer la satisfacción maternal con los cuidados de salud recibidos durante el parto es un aspecto de gran relevancia para las madres, profesionales y gestores sanitarios, siendo un indicador de calidad asistencial. Existe una amplia variedad de instrumentos para medir la satisfacción maternal. Sin embargo, muchos difieren en contenido y calidad metodológica, evidenciando una dudosa utilidad, y la mayoría están dirigidos a mujeres sanas con embarazos de bajo riesgo obstétrico, ignorando la satisfacción en mujeres con bebés prematuros. Objetivos El objetivo general es analizar la satisfacción de la…
Diversification in evolutionary arenas - assessment and synthesis
2019
Abstract Understanding how and why rates of evolutionary diversification vary is a central issue in evolutionary biology and ecology. The concept of adaptive radiation has attracted much interest, but is metaphorical and verbal in nature, making it difficult to quantitatively compare different evolutionary lineages or geographic regions. In addition, the causes of evolutionary stasis are relatively neglected. Here we review the central concepts in the evolutionary diversification literature and bring these together by proposing a general framework for estimating rates of diversification and quantifying their underlying dynamics, which can be applied across clades and regions and across spat…
Three-dimensional core-collapse supernovae with complex magnetic structures: I. Explosion dynamics
2021
Magnetic fields can play a major role in the dynamics of outstanding explosions associated to violent events such as GRBs and hypernovae, since they provide a natural mechanism to harness the rotational energy of the central proto-neutron star and power relativistic jets through the stellar progenitor. As the structure of such fields is quite uncertain, most numerical models of MHD-driven core-collapse supernovae consider an aligned dipole as initial magnetic field, while the field's morphology can actually be much more complex. We present three-dimensional simulations of core-collapse supernovae with more realistic magnetic structures, such as quadrupolar fields and, for the first time, an…
The impact of non-dipolar magnetic fields in core-collapse supernovae
2019
The magnetic field is believed to play an important role in at least some core-collapse supernovae if its magnitude reaches $10^{15}\,\rm{G}$, which is a typical value for a magnetar. In the presence of fast rotation, such a strong magnetic field can drive powerful jet-like explosions if it has the large-scale coherence of a dipole. The topology of the magnetic field is, however, probably much more complex with strong multipolar and small-scale components and the consequences for the explosion are so far unclear. We investigate the effects of the magnetic field topology on the dynamics of core-collapse supernovae and the properties of forming proto-neutron star (PNS) by comparing pre-collap…
Collective participation for the sustainable redevelopment of degraded environments and urban public space
2022
The use of participatory processes as useful tools for the regeneration of the built environment is urgently topical, also in view of the inclusive forms of decision-making that have been introduced for years by ministerial and European standards. The research is part of a well-structured cultural and regulatory context characterised by new and interesting experiments in the field. Studying the participatory process as a useful strategy for conflict management and for the construction of new regenerative models in fact also implies a clarification of "what is meant by participation and the participatory project. At the same time, as widely testified to by the production of manuals in recent…
Transnational ties: Resource or stressor on Peruvian migrants' well‐being?
2020
This paper explores the role of types and the intensity of transnational ties for migrants' well‐being from a global perspective. Based on a literature review, two competing hypotheses are formulated—transnational resources versus transnational stress—according to which transnational ties have either a positive or a negative effect on migrants' well‐being. Drawing on data from a large‐scale survey of Peruvian migrants worldwide, this paper examines the strength and direction of the relationship between Peruvian migrants' transnational ties and poor well‐being, the latter measured as depression/loneliness as a principal concern. While the multivariate regression results do not support the tr…
