Assessing IAQ in existing residential buildings within a performance-based regulatory framework through a predictive model
No full textAt the Eduardo Torroja Institute for Construction Sciences (IETcc), which is a research institution belonging to the Spanish National Research Council (CSIC), studies are being conducted to correlate the outcomes of real CO2 measurements in rooms where the occupants have been able to behave freely with factors such as the season of the year, the surface area of the dwelling, the permeability, or the number of occupants. The a priori intention is not to ascertain how occupants behave, but rather to ascertain the final effect and other factors may have on IAQ. These relationships are proving to be significant enough to develop predictive statistical models with high predictive capability. The current approach is to use parameters that are easily obtainable on a large scale, such as floor area, year of construction, etc., in order to avoid factors that require field measurements such as permeability.
The objective of these models is to provide useful insights that could inform the development of IAQ regulations, guidelines or building renovation plans. These insights could be used to:
- assess the potential IAQ in a given neighbourhood based on its building typology and construction characteristics;
- identify building typologies that are more prone to IAQ problems;
- evaluate the differences in occupant behaviour according to geographical location, climate, socio-economic level, etc.Peer reviewe
Arte en expansión. Puentes de la creación española contemporánea
No full text"Arte en expansión. Puentes de la creación española contemporánea" plantea una aproximación al arte español de los siglos XX y XXI, sus protagonistas y su proyección, desde la reflexión sobre el desbordamiento de la disciplina histórico-artística y el cuestionamiento de los relatos heredados. Un análisis conjunto, en definitiva, de un trayecto expansivo y de conexiones con el que no solo se atiende a los acercamientos, intercambios o puentes tendidos entre escenas y creatividades separadas física, conceptual, estética o socio-políticamente, sino también a la superación de los límites genéricos y tradicionales impuestos a la mirada sobre la creación artística española y a sus fórmulas historiográficas y metodológicas de estudio. De modo que, a través de diferentes estudios de casos, agrupados en torno al compromiso y la oficialidad, la recepción y fortuna crítico-artística y la imbricación y transferencia creativa, se presenta aquí una representativa panorámica de un arte que, a pesar de sus condicionantes sociopolíticos, estéticos y culturales, no ha dejado de interrelacionarse y ensancharse.Financiación asociada al proyecto de I+D+I: Puentes creativos.

'Fuentes renacentistas en la Lira sacro-hispana (ca. 1852-1860) de Hilarión Eslava: atribuciones conflictivas entre Juan Navarro y Miguel Navarro'. Resumen de comunicación presentada el 23/10/2024 en el XI Congreso de la Sociedad Española de Musicología, Musicología: historias (inter)conectadas. Elche, 23 al 26 de octubre de 2024.
No full textLa pionera colección Lira sacro-hispana (ca. 1852-1860), publicada por Hilarión Eslava en diez volúmenes, contiene ediciones de obras de compositores españoles del pasado que en algunos casos siguen siendo las únicas disponibles. Se desconocen las fuentes musicales empleadas por Eslava, que no fueron indicadas en la publicación. En esta comunicación propongo una primera aproximación a las posibles fuentes renacentistas empleadas por Eslava en los tomos 1 y 2 de la mencionada colección, dedicados al siglo XVI
What Would It Take to Continue Feeding the World’s Population? From Family Farming to a New, More Plural, Diverse and Technological Model of Producing Foods
No full textThe world population is continuously increasing. Increases in crop productivity are needed to fulfil food demands, although this approach is not the only solution to the problem. Yields below 2.4% of productivity increase per year would risk food security and lead to prices much higher than reasonable. Advances in potential yield and through yield gap closing are required. In addition, climate change threatens global food production and end-product quality. Setting aside extreme events, such as prolonged droughts or floods, the three main factors associated with climate change are increased temperatures, the rainfall reduction, and the increased atmospheric CO2 concentration. All these three factors impact food production and its quality. Growers should adapt to this new scenario. The key to success in feeding the world’s population in a changing climate will be to achieve a global farmer community with proper skills, an informed population and well-oriented research.Peer reviewe
Entre lo europeo y lo colonial. El Museo Canario circulación de restos humanos, raza y representación (1879-1900)
No full textEn 1879 se funda el Museo Canario. Es una institución privada que hoy en día exhibe una impresionante colección de objetos referentes al pasado prehispánico de las Islas Canarias. Aunque desde el inicio albergó una estimable colección de historia natural, su principal objeto era, y todavía es, todo aquello relacionado con los orígenes de la población que habitó las Islas antes de la conquista castellana del siglo xv. Era, y es, una institución museística, pero también biblioteca y archivo. En ella los objetos arqueológicos como pieles, cerámica, molinos, eran importantes. Pero desde un punto de vista amplio la biología prevalecía sobre la cultura: la sección de lo que hoy conectaríamos con la antropología física era la estrella de sus fondos, lo que se materializaba en una gran atención a los restos humanos (momias, cráneos, huesos largos)

Numerical renormalization group calculations for magnetic impurity systems with spin-orbit coupling and crystal-field effects
No full textExploiting symmetries in the numerical renormalization group (NRG) method significantly enhances performance by improving the accuracy, increasing the computational speed, and optimizing the memory efficiency. Published codes focus on continuous rotations and unitary groups, which generally are not applicable to systems with strong crystal-field effects. The PointGroupNRG code implements symmetries related to discrete rotation groups, which are defined by the user in terms of Clebsch-Gordan coefficients, together with particle conservation and spin rotation symmetries. In this paper we present a new version of the code that extends the available finite groups, previously limited to simply reducible point groups, in a way that all point and double groups become accessible. It also includes the full spin-orbital rotation group. Moreover, to improve the code's flexibility for impurities with complex interactions, this new version allows to choose between a standard Anderson Hamiltonian for the impurity or, as another novel feature, an ionic model that requires only the spectrum and the impurity Lehmann amplitudes.We acknowledge grants No. IT-1527-22, funded by the Department of Education, Universities and Research of the Basque Government; PID2022-137685NB-I00, funded by MCIN/AEI 10.13039/501100011033/ and by “ERDF A way of making Europe”, and PRE2020-092046, funded by the Spanish MCIN.Peer reviewe
Recent advances in graphene-based nano-membranes for desalination
No full textThe demand for desalination is steadily rising due to dwindling fresh water sources and the abundant saline water in our oceans. Among the various techniques available, membrane-based methods stand out as particularly promising. Graphene is the most extensively researched material in recent times and is rapidly gaining traction in desalination because of its unique features, including its nano-pore sizes. This article discusses the advancements in graphene-based nano-membranes for desalination, driven by the urgent need for potable water. It outlines the potential of these membranes to enhance the desalination process, highlighting specific research gaps related to desalination techniques, graphene materials, membrane casting methods, and the performance of different membranes. The article also explores the mechanics of desalination and contrasts the efficacy of various graphene membranes derived from distinct graphene composites. Moreover, it touches upon the challenges and future prospects of applying graphene nano-membranes to mainstream desalination processes. While graphene-based nano-membranes are still in their developmental phase, their substantial potential for desalination and other processes cannot be overlooked
