One-pot synthesis and characterization of subnanometre-size benzotriazolate protected copper clusters
2012
A simple one-pot method for the preparation of subnanometre-size benzotriazolate (BTA) protected copper clusters, Cu(n)BTA(m), is reported. The clusters were analyzed by optical and infrared spectroscopy, mass spectrometry and transmission electron microscopy together with computational methods. We suggest a structural motif where the copper core of the Cu(n)BTA(m) clusters is protected by BTA-Cu(i)-BTA units.
Grazing intensity in subarctic tundra affects the temperature adaptation of soil microbial communities
2015
Abstract Grazing by large ungulates, such as reindeer (Rangifer tarandus L.), in subarctic tundra exerts a considerable effect on the soil microclimate. Because of higher insulation by the aboveground vegetation in light versus heavily grazed areas, soil temperatures during the growing season are considerably higher under heavy grazing. Here, we hypothesized that these grazer-induced changes in soil microclimate affect the temperature sensitivity of soil microbial activity. To test this hypothesis, we conducted soil incubations at different temperatures (4 °C, 9 °C and 14 °C) for six weeks using soils from sites with contrasting long-term grazing intensities. Microbial respiration at low te…
Addressing Complexity in Science|Environment|Health Pedagogy
2019
This paper aims to discuss complexity as a key feature for understanding the role of science knowledge in environmental and health contexts—a central issue in Science|Environment|Health pedagogy. Complex systems are, in principle, not predictable. In different contexts, ephemeral mechanisms produce different, sometimes completely unexpected results. The art of decision-making in complex contexts is to take scientific knowledge into account but to interpret its meaning in terms of concrete complex contexts. This is illustrated by four empirical studies on Science|Environment|Health issues, presented midway through this paper. The findings underscore the importance of introducing complexity i…
Education et complexité : recherche, formation, pratiques
2014
International audience; Cet ouvrage présente les actes du colloque « Education à la santé etcomplexité : Recherches, Formations et Pratiques » qui constituait le4ème colloque international d’UNIRéS, Réseau des universités pour l’éducationà la santé (E.S). Cette 4ème édition, qui a réuni près de 200 chercheurs,formateurs et praticiens, a été portée par la Commission Scientifique duRéseau UNIRéS, nouvellement créé en 2012.C’est à partir de la notion de complexité, dans son acception holistique,que nous avons invité les participants à mener une réflexion autour desquestions d’éducation et de santé, en mettant en exergue la complexité desliens qui se tissent entre éducation, santé et formation.…
Vers une géo-ontologie pour les Systèmes Energétiques Territoriaux (SET)
2009
International audience; Cette communication vise à explorer les bases d'une ontologie de domaine, à travers une illustration géographique de la thématique énergétique, reposant sur la considération des Systèmes Energétiques Territoriaux. Dans une perspective d'observation des territoires et d'aide à la décision, l'objectif final est de parvenir à une instrumentation sous la forme d'un observatoire. Cette application informatique nécessite de structurer et de représenter des connaissances. Elle s'accompagne d'une phase préalable de modélisation qui consiste en l'identification des entités significatives du domaine, de la sémantique à leur affecter, et des processus à leur attacher. De plus, …
Du territoire au territoire par l'observation, prendre en compte la diversité des territoires et adapter les méthodes et les outils aux nouvelles dem…
2008
We propose a conceptual and graphical model of the territory built from an empirical intuitive and deductive approach of systemic paradigm of territorialization. This model is based on an individualized approach before being extended to the collective level. It is first seen in the context of the evolution of the concept in scientific thinking. Then, we introduce it in understanding the dynamics of the territory, under the paradigm of territorial intelligence, through observation and observatories that we adapt to the context of governance systems at different scales.

La destrucció del patrimoni artístic i la seua reconstrucció. Un exercici de microhistòria: el cas de Llíria i la Confraria de la Sang (1936-1949)
2020
The problem of artistic destruction and its reconstruction has been little studied. Using a microhistorical analysis method, we study the town of Lliria (Valencia) and its brotherhood of ?La Sang de Jesucrist? (had a great heritage from the 16th to the 19th centuries), and we also analyze how and why this destruction and reconstruction was generated during the context of the civil war. We use and combine different sources (public of the ?Causa General? and private of the ?Minute Books?) for this research, with the intention of specifying the analysis of this complex process. We also explain social and artistic relationships of these two processes, that help us study the workshops of the mos…
Decompressive Craniectomy Improves QTc Interval in Traumatic Brain Injury Patients
2020
Background: Traumatic brain injury (TBI) is commonly associated with cardiac dysfunction, which may be reflected by abnormal electrocardiograms (ECG) and/or contractility. TBI-related cardiac disorders depend on the type of cerebral injury, the region of brain damage and the severity of the intracranial hypertension. Decompressive craniectomy (DC) is commonly used to reduce intra-cranial hypertension (ICH). Although DC decreases ICH rapidly, its effect on ECG has not been systematically studied. The aim of this study was to analyze the changes in ECG in patients undergoing DC. Methods: Adult patients without previously known cardiac diseases treated for isolated TBI with DC were studied. EC…
Il primo concorso per il Palazzo di Giustizia a Roma del 1884. Ricostruzione critica del progetto di Ernesto Basile
2019
1. Breve descrizione dell’oggetto di studio Il concorso del Palazzo di Giustizia di Roma si svolge in quattro fasi svolte tra il 1884 e il 1887. Il progetto per il primo concorso, del 1884, redatto dall’allora giovanissimo Ernesto Basile (Palermo 1857-1932), rivela una grande perizia progettuale che trasforma il complesso programma funzionale in un austero edificio in stile neofiorentino. I disegni originari dell’opera, non realizzata, conservati presso la Dotazione Basile del Dipartimento di Architettura dell’Università di Palermo, sono stati oggetto di studio propedeutico alle fasi di analisi, interpretazione e ricostruzione congetturale del modello digitale. 2. Stato dell’arte e riferime…
