Porous aerosol in degassing plumes of Mt. Etna and Mt. Stromboli

2016

Abstract. Aerosols of the volcanic degassing plumes from Mt. Etna and Mt. Stromboli were probed with in situ instruments on board the Deutsches Zentrum für Luft- und Raumfahrt research aircraft Falcon during the contrail, volcano, and cirrus experiment CONCERT in September 2011. Aerosol properties were analyzed using angular scattering intensities and particle size distributions simultaneously measured with the Polar Nephelometer and the Forward Scattering Spectrometer probes (FSSP series 100 and 300), respectively. Aerosols of degassing plumes are characterized by low values of the asymmetry parameter (between 0.6 and 0.75); the effective diameter was within the range of 1.5–2.8 µm and the…

The primary volcanic aerosol emission from Mt Etna: Size-resolved particles with SO2 and role in plume reactive halogen chemistry

2018

International audience; Volcanoes are an important source of aerosols to the troposphere. Within minutes after emission, volcanic plume aerosol catalyses conversion of co-emitted HBr, HCl into highly reactive halogens (e.g. BrO, OClO) through chemical cycles that cause substantial ozone depletion in the dispersing downwind plume.This study quantifies the sub-to-supramicron primary volcanic aerosol emission (0.2-5 μm diameter) and its role in this process. An in-situ ground-based study at Mt Etna (Italy) during passive degassing co-deployed an optical particle counter and Multi-Gas SO2 sensors at high time resolution (0.1 Hz) enabling to characterize the aerosol number, size-distribution and…

Influences of atomization process and precursor material on the compaction mechanisms and metallurgical properties of parts developed by HIP

2022

Hot Isostatic pressing process is based on the densification of metals powders to near net shape parts with higher mechanicals properties than forged chemical equivalent. The precursor material can influence the parts properties. Thus the aims of this these is to understand the influence of the powder properties on the HIP parts. The particles characterization and the elements and compound monitoring during the HIP cycle allowed to understand the different oxidations phenomenons and their impact on the mechanical properties of parts. The comparison of differents powders batches with identical particles size repartition or identical chemical composition showed that the chemical composition a…

How Much Money Do You Need to Feel Taller? Impact of Money on Perception of Body Height

2021

Body height is considered to be one of the most important reproductive signals. However, there are only a few publications on what influences the sense of whether we assess ourselves as tall or short. In the present contribution, the psychological impact of money on the evaluation of a person’s own height was tested. We performed two experimental studies in which the respondents had contact with different amounts of money and were asked to evaluate their body height with the use of a laser pointer. The first experiment (N = 61) showed that contact with money significantly increased subjective height evaluation, and the effect was independent of participants’ real body height. The second exp…

Representation of ASD in mass media: analysis of a generalist newspaper

2020

Los medios de comunicación influyen notablemente en sus consumidores, por lo que no son meros informadores, sino que también son creadores de opinión. Este hecho es relevante para el ámbito de la inclusión, en tanto que las necesidades específicas de apoyo educativo son también un tema tratado por los medios de comunicación. En el presente estudio se analizan los artículos que abordan la temática relacionada con el Trastorno del Espectro Autista (TEA) en el diario El País durante el año 2017. Los resultados del análisis de contenido de los artículos indican que el TEA fue un tema de interés en el año 2017. Los contenidos más recurrentes fueron las causas del TEA, frecuentemente desmintiendo…

Mitigating the Climate Change Impacts of Aviation through Behavioural Change

2020

Aviation plays a crucial role for economic development and social welfare, but at the same time it also significantly contributes to climate change. Therefore, if the industry wants to follow the same growth path as it has in the past, it will need to mitigate its environmental impacts more seriously or it may otherwise face regulatory restrictions. The current literature has discussed five mitigation strategies. These are technological changes, market-based changes, operational changes, regulatory changes and behavioural changes. While several authors have regarded behavioural changes as the measure with the greatest mitigation potential, it is also the measure that has received far less a…

Evaluación etnobotanica de la Yareta (Azorella compacta) en Arequipa (Perú) y sus posibles aplicaciones

2013

Abstract – Ethnobotanical study of the Yareta Arequipa plant (Azorella compacta Phil) and its possible applications. – The aim of this work is the ethnobotanical characterisation of the Yareta Arequipa plant (Azorella compacta Phil), to report indications about the uses of the Yareata plant by “Salinas y Aguada Blanca” National Reserve (RNSAB) populations and to find its possible applications. The survey has been lead on nine communities of the Arequipa Region (Peru), it concerned the actual degree of conservation of the plants, the botanical description and classification, the ecological characterization, the use and the distribution in ethnomedicine and ethnopharmacology and all the uses …

Azorella compacta (Yareta): pianta endemica degli altipiani andini del Sud America. – Si riportano i risultati di una ricerca sugli usi della Azorella compacta Phil da parte delle popolazioni sudamericane del Perù, Argentina, Cile e Bolivia, allo scopo di realizzare una documentazione etnobotanica di partenza per possibili applicazioni pratiche della pianta. La sperimentazione sulla A. compacta ha preso in esame lo stato attuale di conservazione, la classificazione e descrizione botanica, l’ecologia, la distribuzione, l’utilizzazione in etnomedicina e etnofarmacologia e altre possibili impieghi. Dalla suddetta esperienza è emerso che tutte le comunità in studio,dei suddetti Paesi, utilizzan…

A balanced score card approach to measuring the impact of tourism

2012

The nature of tourism and the spheres of activity relevant to managing it are changing both in character and in scope. A “territorial space”, which is not defined simply by geographical boundaries, but also by physical and intangible as well as actual and virtual boundaries is offered as a framework within which to conceptualize and approach planning and managing tourism in the newly evolved reality, and the BSC is as an effective tool for facilitating the implementation of a new approach in evaluating and studying the impacts of tourism. The “territory” concept could serve well as an organizing principle in this research and the Italian experiment on tourism districts will provide an ideal…
