Automated detection of discontinuities in EUREF permanent GNSS network stations due to earthquake events

[EN] The EUREF Permanent GNSS Network (EPN) provides the users with data and products such as station coordinate time series. These are subject to possible discontinuities and trend changes, being earthquake events one of the possible natural causes for these variations. We present here a fully automated tool for the analysis of the coordinate time series of EPN stations located in the desired neighbourhood of an earthquake epicentre. The tool is made freely available to the public and applied here to two significant earthquake events occurred in Europe in recent years, where several trend changes and jumps are revealed.Baselga Moreno, S.; Najder, J.

Primer registro del grupo Pseudodiamesa branickii (Diptera: Chironomidae: Diamesinae) del centro de México

Larvae and pupae of the Pseudodiamesa branickii species-group (Makarchenko & Makarchenko, 1999) (Diptera: Chironomidae) were found in 2 high-altitude lakes (El Sol and La Luna, 4,200 m asl), in the crater of the Nevado de Toluca volcano, in central Mexico. This is the first record of the genus in Mexico, and its southernmost report from a location that represents a transitional zone between the Nearctic and Neotropical regions. New information on the ecology and biogeographical distribution of the species-group is given.Se identificaron ejemplares de larvas y pupas del grupo Pseudodiamesa branickii (Makarchenko y Makarchenko, 1999) (Diptera: Chironomidae) en 2 lagos de altura (El Sol y La Luna, 4,200 m snm), ubicados dentro del cráter del volcán Nevado de Toluca, en el centro de México. Éste es el primer reporte para México y la localización más austral del género, en una zona transicional entre las regiones Neártica y Neotropical. Se presenta nueva información sobre la ecología y la distribución biogeográfica de este grupo.Fil: Moreno, Joanna. Universidad Nacional Autónoma de México; MéxicoFil: Massaferro, Julieta.

Un pacto con lo "insignificante": una relación entre el dibujo y el espacio

Este trabajo final de máster es una investigación práctica con el objetivo de realizar una propuesta plástica mediante la búsqueda de soluciones a la necesidad de relacionar el medio bidimensional del dibujo con el espacio tridimensional en el que habitamos, a partir de la cotidianidad como pie para la creación con la que se pretende exaltar la importancia de la vida habitual del sujeto ordinario, su tiempo y la historia que en este realiza.Moreno Munévar, JC.

Effluents and residues from industrial sites for carbon dioxide capture: a review

The adverse effects of climate change calls for the rapid transformation of manufacturing processes to decrease the emissions of carbon dioxide. In particular, a lower carbon footprint can be achieved by capturing carbon dioxide at the site of emission. Here we review the use of industrial effluents, waste and residues to capture carbon dioxide. Waste include steelmaking slag, municipal solid waste incinerator ashes, combustion fly ash, black liquor, paper mill waste, mining waste, cement waste, construction and demolition waste, waste from the organic industry, and flue gas desulfurization gypsum waste. Capture capacities range from 2 to 800\ua0kg of carbon dioxide per ton of waste, depending on processes, waste type and conditions. Cement waste and flue gas desulfurization gypsum\ua0waste show the highest capture capacity per ton of waste

What shapes a galaxy? - Unraveling the role of mass, environment and star formation in forming galactic structure

We investigate the dependence of galaxy structure on a variety of galactic and environmental parameters for ~500,000 galaxies at z<0.2, taken from the Sloan Digital Sky Survey data release 7 (SDSS-DR7). We utilise bulge-to-total stellar mass ratio, (B/T)_*, as the primary indicator of galactic structure, which circumvents issues of morphological dependence on waveband. We rank galaxy and environmental parameters in terms of how predictive they are of galaxy structure, using an artificial neural network approach. We find that distance from the star forming main sequence (Delta_SFR), followed by stellar mass (M_*), are the most closely connected parameters to (B/T)_*, and are significantly more predictive of galaxy structure than global star formation rate (SFR), or any environmental metric considered (for both central and satellite galaxies). Additionally, we make a detailed comparison to the Illustris hydrodynamical simulation and the LGalaxies semi-analytic model. In both simulations, we find a significant lack of bulge-dominated galaxies at a fixed stellar mass, compared to the SDSS. This result highlights a potentially serious problem in contemporary models of galaxy evolution.Comment: Accepted to MNRAS. 31 pages, 15 figure

Personal exposure to indoor pollution during everyday activities of hybrid workers in the UK

Western lifestyles and urbanisation have led many people to spend most of their time indoors. Existing studies have described the impact of indoor air quality (IAQ) on health and well-being. However, IAQ assessments typically focus on home or office settings. Hybrid working and a change in transport behaviour raise the question of what are the new trends of personal exposure to air pollution among all daily activities including home, office and transport. This study discusses the results from IAQ monitoring in everyday life of UK hybrid workers. It uses a personal air quality monitor to track daily activities to measure trends of personal exposure to air pollutants and identify spot-events of high exposure. The results present the diurnal and spatial variation of five indoor air pollutants: PM1, PM2.5, PM10, NO2 and VOC. Data was collected at 1-minutes intervals in an open plan office, a house with a small home office but also during the commuting between Glasgow (Scotland) and Lancaster (North West England) by train and between Lancaster and Southampton (South England) by car at different times of the day and traffic conditions. The findings discuss hybrid workers' spatiotemporal personal exposure trends to air pollutants and contextualise them to short- and long-term health risks. The paper concludes with recommendations to minimise personal exposure to indoor and outdoor air pollutants and mitigate health risks by identifying “high risk” activities in spatiotemporal relation to air pollutants

El suicidio y el absurdo de la existencia desde la mirada filosófica de Albert Camus

El suicidio es un tema complejo y delicado que ha sido abordado desde diferentes perspectivas a lo largo de la historia humana. En este trabajo, el enfoque para analizar el suicidio parte desde la mirada filosófica de Albert Camus, quien consideraba que el absurdo de la existencia era una de las principales causas del suicidio en la sociedad contemporánea. En este sentido, nuestro objetivo es explorar cómo la filosofía de Albert Camus puede ayudarnos a entender las raíces del problema del suicidio en la actualidad y cómo podemos abordarlo desde una perspectiva filosófica y contextualizada. Para ello, se analiza las principales obras de Camus, como “El mito de Sísifo” y “El extranjero”, y se relaciona con algunos problemas sociales tales como la migración, la violencia y el desempleo que afectan a nuestra sociedad actual. En definitiva, este trabajo pretende contribuir al debate sobre el suicidio y ofrecer una reflexión profunda sobre el sentido de la vida desde la perspectiva filosófica de Albert Camus.Suicide is a complex and delicate subject that has been approached from different perspectives throughout human history. In this paper, we will focus on analyzing suicide from the philosophical viewpoint of Albert Camus, who considered the absurdity of existence to be one of the main causes of suicide in contemporary society. In this sense, our aim is to explore how Camusian philosophy can help us understand the roots of the problem of suicide today and how we can approach it from a more humane and comprehensive perspective. To do so, we will analyze Camus' main works, such as "The Myth of Sisyphus" and "The Stranger", and relate them to some social problems such as migration, violence and unemployment that affect our society today. In short, this paper aims to contribute to the debate on suicide and to offer a deep reflection on the meaning of life from the philosophical perspective of Albert Camus.0000-0002-9706-948
