Réactions redox du plutonium et de l'antimoine avec des minéraux de fers en milieux anoxique

Redox reactions of Sb(V) and Sb(III) with mackinawite (FeS) and of aqueous Pu(III) and Pu(V) with various Fe(II)‐bearing minerals and Fe(III)‐oxides have been investigated under anoxic conditions. X‐ ray absorption spectroscopy was used to analyze oxidation state and local coordination environment of Sb and Pu associated with the solid phase. After reaction with mackinawite, chukanovite and...

Analyse spatiale, évaluation et cartographie du risque glissement de terrain

Spatial analysis and GIS technology are still seldom used to evaluate and map landslide risk. Especially, few studies concern the automatic mapping of landslide risk at large scales (1:10,000) corresponding to the scale of the legal regulation plans in France. Maquaire et al., Analyse spatiale du risque « glissement de terrain » 2 This paper presents a three-step procedure to map landslide risk...

Impact du changement d'échelle sur l'étude des causes des feux de forêts du sud-est de la France

The Modifiable Areal Unit Problem (MAUP) is a well-known issue related to the influence of the spatial support on statistical observations. It occurs when different spatial units making different spatial partitions are used and when the resulting measures vary according to those partitions. In this paper, we first draw a state of the art. Considering the particular problem of (up)scaling, we pr...
