Nitrogen isotopes in tooth enamel record diet and trophic level enrichment: results from a controlled feeding experiment
2021
Nitrogen isotope ratios (δ15N) are a well-established tool for investigating the dietary and trophic behavior of animals in terrestrial and marine food webs. To date, δ15N values in fossils have primarily been measured in collagen extracted from bone or dentin, which is susceptible to degradation and rarely preserved in deep time (>100,000 years). In contrast, tooth enamel organic matter is protected from diagenetic alteration by the mineral structure of hydroxyapatite and thus is often preserved over geological time. However, due to the low nitrogen content (<0.01 %) of enamel, the measurement of its nitrogen isotopic composition has been prevented by the analytical limit…
Variability and Uncertainty Challenges in Scaling Imaging Spectroscopy Retrievals and Validations from Leaves Up to Vegetation Canopies
2019
Imaging spectroscopy of vegetation requires methods for scaling and generalizing optical signals that are reflected, transmitted and emitted in the solar wavelength domain from single leaves and observed at the level of canopies by proximal sensing, airborne and satellite spectroradiometers. The upscaling embedded in imaging spectroscopy retrievals and validations of plant biochemical and structural traits is challenged by natural variability and measurement uncertainties. Sources of the leaf-to-canopy upscaling variability and uncertainties are reviewed with respect to: (1) implementation of retrieval algorithms and (2) their parameterization and validation of quantitative products through…

Unravelling textural heterogeneity in obsidian:shear-induced outgassing in the Rocche Rosse flow
2016
Obsidian flow emplacement is a complex and understudied aspect of silicic volcanism. Of particular importance is the question of how highly viscous magma can lose sufficient gas in order to erupt effusively as a lava flow. Using an array of methods we study the extreme textural heterogeneity of the Rocche Rosse obsidian flow in Lipari, a 2. km long, 100. m thick, ~. 800. year old lava flow, with respect to outgassing and emplacement mechanisms. 2D and 3D vesicle analyses and density measurements are used to classify the lava into four textural types: 'glassy' obsidian (<. 15% vesicles), 'pumiceous' lava (>. 40% vesicles), high aspect ratio, 'shear banded' lava (20-40% vesicles) and lo…
Assessing vermetid reefs as indicators of past sea levels in the Mediterranean
2020
Abstract The endemic Mediterranean reef building vermetid gastropods Dendropoma petraeum complex (Dendropoma spp) and Vermetus triquetrus develop bio-constructions (rims) on rocky shorelines at about Mean Sea Level (MSL) and are therefore commonly used as relative sea-level (RSL) markers. In this study, we use elevations and age data of vermetid reefs to (1) re-assess the vertical uncertainties of these biological RSL indicators, and (2) evaluate the vertical growth rates along a Mediterranean east-west transect, in attempt to explain the differences found in both growth rates and uncertainties. In Israel, Differential Global Positioning System (DGPS) and laser measurements relative to the …
Ernesto Basile, Vittorio Ducrot e Ignazio Florio all’Esposizione di Milano del 1906: l’ultima stagione propositiva del modernismo palermitano
2011
La partecipazione di Ernesto Basile all’Esposizione di Milano del 1906 avviene all’apice della sua carriera professionale, iniziata un quarto di secolo prima e svolta prevalentemente in Sicilia e a Roma. Nel complesso dell’area di Parco Sempione, con un tono discreto che tuttavia non manca di farsi notare nell’esuberante contesto dell’esposizione, Basile presenta contributi alquanto diversificati: espone una selezione di suoi elaborati progettuali del periodo 1899-1906 in una sorta di mostra personale di architettura; presenta cinque arredi completi eseguiti con rimarchevole perizia dal mobilificio Ducrot; realizza con il padiglione della Casa Florio un’architettura effimera che sarebbe ass…
L'Orchestra di Auschwitz. Inchiesta su Alma Rosé
2023
Il libro è un'inchiesta sulla vita e il tempo di Alma Rosé (1906-1944), nipote di Gustav Mahler, debuttante e ragazza alla moda fra gli anni Venti e Trenta del secolo scorso, violinista il cui talento matura – paradossalmente – mentre l’ombra del nazismo si dispiega sull’Europa e infine direttrice dell’orchestra di Auschwitz. in un’epoca in cui la carriera del direttore d’orchestra era declinata soltanto al maschile. Giunta ad Auschwitz nell’estate 1943 e assegnata dapprima al Block degli esperimenti medici, Alma riuscì in breve tempo a diventare – nel piccolo mondo terribile del Lager – una specie di celebrità: ed è in quelle tenebre, d’altronde, che si svolge l’atto finale del dramma, oss…

Le rire de Beckett
2020
International audience; Il est une vérité que l’on pense devoir admettre : Beckett fait de l’absurde. On attend Godot, il ne viendra jamais, et le théâtre de Beckett est donc la représentation parfaite de cette existence sans but dont nous fûmes affligés à la naissance. Quant à Fin de partie... on finira donc tous dans des poubelles, à se hurler des vérités désagréables. Ce qui est toujours mieux que se faire enterrer dans le sable d’Oh les beaux jours. Nous voudrions ici montrer que Beckett est drôle ! Rions un peu, donc, en attendant la mort !
