The Climats in Burgundy: issues and developments in a winegrowing landscape that has become cultural heritage

2020

L’aire urbaine de Valencia dans le système global des villes : Les effets de la crise économique sur le réseau des liens financiers des entreprises m…

2021

El artículo analiza el impacto que la crisis económica ha tenido sobre las redes de relaciones de propiedad-filiación de las empresas multinacionales, consideradas en la literatura científica como uno de los factores más importantes en la integración de las ciudades en la globalización. El caso de estudio es el área metropolitana de Valencia, un centro de segundo nivel en las redes económicas mundiales que ha sido duramente golpeado por los efectos de la crisis desde 2008. A partir del análisis de bases de datos de empresas multinacionales en dos fechas de referencia, 2010 y 2013, se constata que la crisis económica ha provocado un retroceso en la inserción del área metropolitana en dichas …

Quantification de la dynamique sédimentaire en contexte anthropisé. L'érosion des versants viticoles de Côte d'Or.

2007

The wine slopes of Côte d'Or (Burgundy, France) are subject to the combined effects of runoff/erosion processes and intense cultivation practices. The purpose of this study is to characterize the erosion processes, and to quantify the sedimentary dynamics over different time scales and spatial scales. Sedimentary budgets show that the studied slopes, with grounds that are made very sensitive to the runoff phenomena by intensive mechanisation, are subject to erosion rates of several millimetres per year. Overflow triggering and its extension, which determine sediment transfer distances, are dependent on a runoff threshold. The existence of this threshold is observed through the analysis of t…

Anàlisi de la violència filioparental en centres de menors : un estudi monogràfic

2019

espanolAntecedentes: El principal objetivo de este estudio era conocer las caracteristicas sociodemograficas, judiciales y psicologicas de los menores infractores que habian sido denunciados por violencia filio-parental, asi como elaborar posibles perfiles a partir de dichas caracteristicas. Metodo: Se analizaron expedientes judiciales correspondientes a 56 adolescentes del Centro de Educacion e Internamiento por Medida Judicial de Zaragoza –Espana–, que habian sido internados por violencia filio-parental en el periodo comprendido entre 2006 y 2016.Resultados: Los resultados indican una importante presencia de antecedentes por acogimiento en centros de proteccion de menores, hogares familia…

Modelling the removal and reversible immobilization of murine noroviruses in a Phaeozem under various contamination and rinsing conditions

2018

International audience; Enteric viruses entering the soil with contaminated irrigation water can reach groundwater or be internalized in plants through their roots without being inactivated. Their fate in the soil depends on the virus, the soil and the soil solution. In order to write a mathematical model suitable for a Calcaric Phaeozem, we investigated the removal of murine norovirus and reversible immobilization in aggregate columns according to a saturation procedure, conditions between contamination and rinsing time, temperature and soil solution. Viruses were quantified before and after 0.45‐μm filtration with an RT‐qPCR (real‐time polymerase chain reaction). Experimental results supp…

Toimijuus korkeakoulutettujen suomen oppijoiden visuaalisissa narratiiveissa

2018

This socioculturally informed study explores how highly educated Finnish language learners represent their agency in visual narratives. Learners (n=59) were asked to draw two pictures of themselves as Finnish language users and provide verbal interpretations of the drawings. The aim of using visual narratives is to reach aspects such as feelings and beliefs which might be difficult to express verbally. The data were analyzed first by using visual grammar set out by Kress and van Leeuwen (2006) and secondly by content analysis. The findings suggest that learners saw Finnish language as a tool for oral communication. However, difficulties with speaking and listening appeared to restrict learn…

Regional Farmers’ Perception and Societal Issues in Vineyards Affected by High Erosion Rates

2021

We explore the current situation in a viticultural region in Eastern Spain from a holistic and multifaceted research approach, which allowed us to understand the biophysical conditions, economic cost, social impact, and perception of the farmers’ community to the use of catch crops. A survey of the perception of the farmers, and an assessment of the biophysical impact of catch crops (CC) and tillage (C = Control plot) on soil organic matter, bulk density, infiltration capacity (single ring infiltrometer), and runoff generation and soil erosion (rainfall simulation experiments) was carried out. Two representative fields as study sites were selected in Les Alcusses valley, within Els Alforins…

Gas Emissions From the Western Aleutians Volcanic Arc

2021

The Aleutian Arc is remote and highly active volcanically. Its 4,000 km extent from mainland Alaska to Russia’s Kamchatka peninsula hosts over 140 volcanic centers of which about 50 have erupted in historic times. We present data of volcanic gas samples and gas emission measurements obtained during an expedition to the western-most segment of the arc in September 2015 in order to extend the sparse knowledge on volatile emissions from this remote but volcanically active region. Some of the volcanoes investigated here have not been sampled for gases before this writing. Our data show that all volcanoes host high-temperature magmatic-hydrothermal systems and have gas discharges typical of volc…

A Low-Cost Smartphone Sensor-Based UV Camera for Volcanic SO2 Emission Measurements

2017

Recently, we reported on the development of low-cost ultraviolet (UV) cameras, based on the modification of sensors designed for the smartphone market. These units are built around modified Raspberry Pi cameras (PiCams; ≈USD 25), and usable system sensitivity was demonstrated in the UVA and UVB spectral regions, of relevance to a number of application areas. Here, we report on the first deployment of PiCam devices in one such field: UV remote sensing of sulphur dioxide emissions from volcanoes; such data provide important insights into magmatic processes and are applied in hazard assessments. In particular, we report on field trials on Mt. Etna, where the utility of these devices in quantif…

A model of degassing for Stromboli volcano

2010

International audience; A better understanding of degassing processes at open-vent basaltic volcanoes requires collection of new datasets of H2O–CO2–SO2 volcanic gas plume compositions, which acquisition has long been hampered by technical limitations. Here, we use the MultiGAS technique to provide the best-documented record of gas plume discharges from Stromboli volcano to date. We show that Stromboli's gases are dominated by H2O (48–98 mol%; mean, 80%), and by CO2 (2–50 mol%; mean, 17%) and SO2 (0.2–14 mol%; mean, 3%). The significant temporal variability in our dataset reflects the dynamic nature of degassing process during Strombolian activity; which we explore by interpreting our gas m…
