Proyecto: cámara de conservación de libros para la Biblioteca Histórica de la Universitat de València

2017

Las dificultades para conseguir unas condiciones ambientales óptimas para la conservación de nuestro patrimonio bibliográfico y el elevado consumo energético necesario para mantenerlas han sido algunas de las premisas que nos han llevado a la proyección y realización de esta cámara de conservación. En ella se ha creado un espacio libre de influencia exterior que facilita la obtención de un clima adecuado y estable, con un consumo mínimo de energía, en el que se controlan los principales factores de degradación ambiental: temperatura y humedad precisas y estables, así como un control minucioso de la contaminación atmosférica y biológica; todo ello dirigido a aumentar la esperanza de vida de …

Le plein air peut-il être travailliste ?

2014

International audience; La nature des liens entre le sommet des organisations et la masse de leurs adhérents est une donnée essentielle pour saisir l’histoire du fait communiste. Elle régule le fonctionnement des structures et détermine largement leurs succès et leurs fragilités. La Fédération sportive et gymnique du travail (FSGT) est fondée en 1934 et incarne à partir de 1950 le versant communiste du mouvement sportif ouvrier français. Organisation de masse du Parti communiste français, censée rapprocher du Parti les jeunes travailleurs et leurs familles, elle n’échappe pas elle-même aux distances qu’elle a pour vocation de réduire entre les dirigeants nationaux et les membres ordinaires.…

Students' school‐level symptoms mediate the relationship between a school's observed moisture problems and students’ subjective perceptions of indoor…

2020

Moisture damage can influence the subjective assessment of indoor air quality (subjective IAQ) in various ways. We studied whether the frequency of symptoms reported across students at school level mediates the relationship between observed mold and dampness in a school building and students' subjective IAQ. To answer this research question, we tested a multilevel path model. The analyzed data were created by merging two nationwide data sets: (a) survey data from students, including information on subjective IAQ (N = 24,786 students); (b) data from schools, including information on mold and dampness in a school building (N = 222). After the background variables were adjusted, schools' obser…

Evolución de la investigación sobre actividad física en el medio natural en educación física: Resultados en Web of ScienceTM desde 1990 a 2016

2017

Monográfico con el título: "Actividades Físicas en el Medio Natural (1ª parte)" Resumen basado en el de la publicación Título, resumen y palabras clave también en inglés Se pretende analizar la evolución del número de publicaciones sobre actividad física en el medio natural en educación física. Para ello, se realizó una búsqueda bibliográfica en la base de datos Web of ScienceTM desde 1990 hasta 2016. Los términos de búsqueda usados se basaron en dos conceptos: 1) actividad física en el medio natural y 2) educación física. Se encontraron un total de 116 resultados, con una media de 4,3 publicaciones por año, observándose una tendencia a aumentar el número de publicaciones a lo largo de los …

Analysis of radionuclide concentration in air released through the stack of a radiopharmaceutical production facility based on a medical cyclotron

2015

Abstract Positron emitting radionuclides are increasingly used in medical diagnostics and the number of radiopharmaceutical production facilities have been estimated to be growing worldwide. During the process of production and/or patient administration of radiopharmaceuticals, an amount of these radionuclides might become airborne and escape into the environment. Therefore, the analysis of radionuclide concentration in the air released to the stack is a very important issue to evaluate the dose to the population living around the plant. To this end, sampling and measurement of radionuclide concentration in air released through the stack of a Nuclear Medicine Center (NMC), provided with a c…

A Simplified LCA Tool for Solar Heating and Cooling Systems

2016

Abstract This paper presents a user-friendly Life Cycle Assessment tool, which aims to support researchers, designers and decision-makers in evaluating the life cycle energy and environmental advantages related to the use of solar heating and cooling (SHC) systems in substitution of conventional ones, considering specific climatic conditions and building loads. The tool was developed within the Task 48 “Quality Assurance & Support Measures for Solar Cooling Systems”, promoted by the International Energy Agency in the framework of the SHC Programme.

Escalating CO2 degassing at the Pisciarelli fumarolic system, and implications for the ongoing Campi Flegrei unrest

2019

Abstract This short communication aims at providing an updated report on degassing activity and ground deformation variations observed during the ongoing (2012–2019) Campi Flegrei caldera unrest, with a particular focus on Pisciarelli, currently its most active fumarolic field. We show that the CO2 flux from the main Pisciarelli fumarolic vent (referred as “Soffione”) has increased by a factor > 3 since 2012, reaching in 2018–2019 levels (>600 tons/day) that are comparable to those typical of a medium-sized erupting arc volcano. A substantial widening of the degassing vents and bubbling pools, and a further increase in CO2 concentrations in ambient air (up to 6000 ppm), have also been detec…

‘Each flight is different’ : Carbon emissions of selected flights in three geographical markets

2017

Air travel is considered the biggest individual climate sin. Avoiding flying, however, seems impossible. In this paper we argue that the flight a passenger chooses can be significant. For this purpose we compared the carbon emissions of selected flights in three geographical markets. We found tremendous differences in the environmental performance of individual flights. Furthermore, we also found that flying with the most modern aircraft or flying non-stop represents, in many cases, the least polluting option. Nevertheless, we were able to show that there are exceptions to this rule. Based on our results, we provide recommendations to the industry and for further research. peerReviewed
