El folklore como forma de identidad cultural y recurso en las aulas de música de Primaria

Actualmente, el folklore es un género musical poco usado en educación y que parece no estar de moda. Sin embargo, el folklore, y no solo el musical, es parte de nuestra vida: gracias a él podemos conocer nuestras raíces y, además, es una seña de identidad cultural. Por ello, consideramos que trabajar con este género en la escuela, y más concretamente como recurso en el aula de Educación Musical de Primaria, puede ser muy beneficioso por ser una fuente de conocimiento para nuestro alumnado, a través de la que desarrollar multitud de habilidades.Grado en Educación Primari

pH-triggered removal of nitrogenous organic micropollutants from water by using metal-organic polyhedra

Altres ajuts: this work funded by the CERCA Programme/Generalitat de Catalunya and through a fellowship (LCF/BQ/PR20/11770011) from the "la Caixa" Foundation (ID 100010434). L.H.L. acknowledges the support from the Spanish State Research Agency (PRE2019-088056).Water pollution threatens human and environmental health worldwide. Thus, there is a pressing need for new approaches to water purification. Herein, we report a novel supramolecular strategy based on the use of a metal-organic polyhedron (MOP) as a capture agent to remove nitrogenous organic micropollutants from water, even at very low concentrations (ppm), based exclusively on coordination chemistry at the external surface of the MOP. Specifically, we exploit the exohedral coordination positions of Rh-MOP to coordinatively sequester pollutants bearing N-donor atoms in aqueous solution, and then harness their exposed surface carboxyl groups to control their aqueous solubility through acid/base reactions. We validated this approach for removal of benzotriazole, benzothiazole, isoquinoline, and 1-napthylamine from water

Early Miocene dispersal of the lizard Varanus into Europe : reassessment of vertebral material from Spain

Iberovaranus Hoffstetter, 1969 was erected as a monotypic genus of varanine varanid lizard on the basis of a single trunk vertebra from the Miocene of Spain. Thanks to the study of the holotype, as well as of a still undescribed cervical vertebra from the same locality, we show that the vertebral morphology of Iberovaranus is contained within the known variability of Varanus. Therefore, Iberovaranus Hoffstetter, 1969 is considered a subjective junior synonym of Varanus Merrem, 1820, and the species Iberovaranus catalaunicus Hoffstetter, 1969 should be considered a nomen dubium

Electrical monitoring of infection biomarkers in chronic wounds using nanochannels

Chronic wounds represent an important healthcare challenge in developed countries, being wound infection a serious complication with significant impact on patients’ life conditions. However, there is a lack of methods allowing an early diagnosis of infection and a right decision making for a correct treatment. In this context, we propose a novel methodology for the electrical monitoring of infection biomarkers in chronic wound exudates, using nanoporous alumina membranes. Lysozyme, an enzyme produced by the human immune system indicating wound infection, is selected as a model compound to prove the concept. Peptidoglycan, a component of the bacterial layer and the native substrate of lysozyme, is immobilized on the inner walls of the nanochannels, blocking them both sterically and electrostatically. The steric blocking is dependent on the pore size (20 - 100 nm) and the peptidoglycan concentration, whereas the electrostatic blocking depends on the pH. The proposed analytical method is based on the electrical monitoring of the steric/electrostatic nanochannels unblocking upon the specific degradation of peptidoglycan by lysozyme, allowing to detect the infection biomarker at 280 ng/mL levels, which are below those expected in wounds. The low protein adsorption rate and thus outstanding filtering properties of the nanoporous alumina membranes allowed us to discriminate wound exudates from patients with both sterile and infected ulcers without any sample pre-treatment usually indispensable in most diagnostic devices for analysis of physiological fluids. Although size and charge effects in nanochannels have been previously approached for biosensing purposes, as far as we know, the use of nanoporous membranes for monitoring enzymatic cleavage processes, leading to analytical systems for the specific detection of the enzymes has not been deeply explored so far. Compared with previously reported methods, our methodology presents the advantages of no need of neither bioreceptors (antibodies or aptamers) nor competitive assays, low matrix effects and quantitative and rapid analysis at the point-of-care, being also of potential application for the determination of other protease biomarkers.Peer ReviewedPostprint (published version

Final testing, pre-launch activities, launch and post-launch analysis of a sounding rocket made by students in Spain

This paper summarizes the final launch preparation tests, the operations before, during, and after the launch, and the results of the launch of a supersonic sounding rocket developed by university students in Spain with the collaboration of INTA (National Institute of Aerospace Technology). The students are part of the Cosmic Research association, based at the Polytechnic University of Catalonia ESEIAAT, and the rocket is called Bondar. INTA is a Public Research Organization under the Spanish Ministry of Defense dedicated to scientific research and development of systems and prototypes in the fields of aeronautics, space, hydrodynamics, security, and defense. The staff of the El Arenosillo Experimentation Center (CEDEA) collaborated in the Bondar mission with their knowledge and launch capabilities. The launch of the rocket took place on the 30 th of November of 2021. Two students from BiSky, a rocketry team from the University of the Basque Country, also participated in this project, specifically in the development of the on-board and ground-based avionics subsystems. The paper presents information on the mission systems, the operations before, during, and after the countdown to the launch, the documentation required by INTA-CEDEA for the launch, and the results of said launch. In short, the systems developed by Cosmic Research for the launch are: the rocket, the launch pad, the rocket transport box, the flight simulator, and the ground-based rocket tracking station. The documentation required by INTA includes: a detailed description of the systems, a ground risk assessment, a flight risk assessment, structural analysis, aerodynamic analysis, and a list of countdown operations. Launch post-analysis activities evaluate the performance of systems and operations during the most critical phase of the mission. The Bondar Mission, due to its technical and operational complexity, was the most ambitious project ever developed by students in Spain in the field of rocketry. After a successful launch, Bondar became the highest-flying Spanish student-made rocket, with its apogee around 8 km AGL (Above Ground Level

(Bio)Functionalisation of Metal-Organic Polyhedra by Using Click Chemistry

The surface chemistry of Metal-Organic Polyhedra (MOPs) is crucial to their physicochemical properties because it governs how they interact with external substances such as solvents, synthetic organic molecules, metal ions, and even biomolecules. Consequently, the advancement of synthetic methods that facilitate the incorporation of diverse functional groups onto MOP surfaces will significantly broaden the range of properties and potential applications for MOPs. This study describes the use of copper(I)-catalysed, azide-alkyne cycloaddition (CuAAC) click reactions to post-synthetically modify the surface of alkyne-functionalised cuboctahedral MOPs. To this end, a novel Rh(II)-based MOP with 24 available surface alkyne groups was synthesised. Each of the 24 alkyne groups on the surface of the "clickable" Rh-MOP can react with azide-containing molecules at room temperature, without compromising the integrity of the MOP. The wide substrate catalogue and orthogonal nature of CuAAC click chemistry was exploited to densely functionalise MOPs with diverse functional groups, including polymers, carboxylic and phosphonic acids, and even biotin moieties, which retained their recognition capabilities once anchored onto the surface of the MOP

Physical characterization of long-lasting hybrid eruptions: the 2021 tajogaite eruption of Cumbre Vieja (La Palma, Canary Islands)

Long-lasting, hybrid eruptions can be of complex description and classification, especially when associated with multiple eruptive styles and multiple products. The 2021 Tajogaite eruption of La Palma, Canary Islands, was associated with a magma-gas decoupled system that resulted in the simultaneous emission of lava flows and tephra plumes from various vents. Even though the tephra blanket (∼2 × 107 m3) represents only 7%–16% of the total erupted volume, it provides fundamental insights into the overall eruptive dynamics. Tephra was mostly dispersed NE-SW due to a complex regional and local wind patterns and was subdivided into 3 units and 11 layers that well correlate at different distances from the vent and with both tremor data and lava emission rate. While plume height varied at the temporal scale of a few hours, the average mass eruption rate associated with the tephra blanket of the different units remained relatively constant (∼3–4 × 103 kg s−1). In contrast, the emission rate of lava largely increased after the first week and remained higher than the overall emission of tephra throughout the whole eruption (average value of ∼6 × 104 kg s−1). Based on a detailed characterization of the tephra blanket in combination with atmospheric wind, tremor, and lava emission trend, we demonstrate the need of (a) multidisciplinary strategies for the description of hybrid eruptions that account for both the duration of individual phases and the quantification of the mass of multiple products, and of (b) dedicated ash dispersal forecasting strategies that account for the frequent variations of eruptive and atmospheric conditions.Research activities were supported by Swiss National Science Foundation (Grant 200020_188757) and by the projects (a) VOLRISKMAC (MAC/3.5b/124) and (b) VOLRISKMAC II (MAC2/3.5b/328), financed by the Program INTERREG VA Spain-Portugal MAC 2014–2020 of the European Commission; (c) Cumbre Vieja Emergencia, financed by the Science and Innovation Ministry, Spanish Government; and (d) Tfassistance, financed by the Cabildo Insular de Tenerife.
