Deep-rooted “thick skinned” model for the High Atlas Mountains (Morocco). Implications for the structural inheritance of the southern Tethys passive …
2006
A re-interpretation of the deep structure of the High Atlas is presented through integration of geophysical and geological data, highlighting the architectural significance of the southern Tethys palaeomargin. Previous crustal models suggest the occurrence of a flat intra-crustal detachment at a depth of � 20 km, a zone where surface thrusts merge and below which the lower High Atlas crust appears continuous. However, within this study seismic refraction data, electrical resistivity surveys and gravity modelling all appear to detect a jump in crustal thickness between the High Atlas and the northern plains. We interpret these data as penetration by thrusts within the ‘‘South-Atlasic fault’’…

Early Warning Systems for Food Security in West Africa: Evolution, Achievements and Challenges
2010
In West Africa, early warning systems (EWSs) for food security have been widely recognized to have contributed, in the last 20 years, to an improved ability to deal with famine emergencies. Nevertheless, despite the advancements in understanding of the environmental and socio-economic dynamics and despite the improved technologies, tackling food security remains a difficult task for decision makers as demonstrated by local food crises in many countries of the region. African Monsoon Multidisciplinary Analysis, while improving the understanding of the monsoon system, allowed us to better orient research challenges to provide EWS with improved products, effectively meeting the needs of end-us…
Thermal remote sensing from Airborne Hyperspectral Scanner data in the framework of the SPARC and SEN2FLEX projects: an overview
2009
Abstract. The AHS (Airborne Hyperspectral Scanner) instrument has 80 spectral bands covering the visible and near infrared (VNIR), short wave infrared (SWIR), mid infrared (MIR) and thermal infrared (TIR) spectral range. The instrument is operated by Instituto Nacional de Técnica Aerospacial (INTA), and it has been involved in several field campaigns since 2004. This paper presents an overview of the work performed with the AHS thermal imagery provided in the framework of the SPARC and SEN2FLEX campaigns, carried out respectively in 2004 and 2005 over an agricultural area in Spain. The data collected in both campaigns allowed for the first time the development and testing of algorithms for …
Seismic velocity structures of Southern Italy from tomographic imaging of the Ionian slab and petrological inferences.
2012
International audience; In this study we have determined detailed Vp and Vs seismic velocity models of the Ionian lithosphere subducting beneath the Tyrrhenian basin and of the surrounding mantle, by applying a post-processing technique to a large sample of local earthquake tomography studies. Our seismic velocity models permit us to infer the presence of low velocity anomalies within the slab, which we interpret as regions that are partially hydrated by fluids released during the subduction process. A petrological interpretation of the velocity anomalies gives new details on the magmatism of the volcanic Aeolian arc. Furthermore our velocity models provide a more detailed description of th…
Compromised nuclear envelope integrity drives TREX1-dependent DNA damage and tumor cell invasion
2021
Although mutations leading to a compromised nuclear envelope cause diseases such as muscular dystrophies or accelerated aging, the consequences of mechanically induced nuclear envelope ruptures are less known. Here, we show that nuclear envelope ruptures induce DNA damage that promotes senescence in non-transformed cells and induces an invasive phenotype in human breast cancer cells. We find that the endoplasmic reticulum (ER)-associated exonuclease TREX1 translocates into the nucleus after nuclear envelope rupture and is required to induce DNA damage. Inside the mammary duct, cellular crowding leads to nuclear envelope ruptures that generate TREX1-dependent DNA damage, thereby driving the …

Functional Aspects of Adrenocholinergic and Peptidergic Innervation about Prostate and Seminal Vesicles in Mammals: A Review
2009
This study was aimed to explain the functional role of mediation in the organs of the male reproductive system (prostate and seminal vesicles of rat and hamster), representing throught the visualization of adrenergic fibres (Falck Method), cholinergic fobres (Martinez-Rodriguez method) and by immunohistochemical methods to detect the P substance and the CGRP (PAP) in glandular structures. The adrenocholinergic and peptidergic mediators have a growing interest for their synergic action in the control of contractility, vasodilatation and most likely, of the secretory activity of the epithelium, probably expressed by andocrine-paracrine mechanisms.
Istruttoria tecnico-scientifica nel giudizio a quo e giudizio di legittimità costituzionale: il caso dell’obbligo vaccinale nella decretazione d’urge…
2022
Muovendo dall’ordinanza n. 38 del 2022 del Consiglio di giustizia amministrativa per la Regione siciliana (CGARS), il contributo si sofferma a) sull’estensione per analogia degli obblighi vaccinali; b) su oscurità ed incoerenze della disciplina sugli obblighi vaccinali in tema di accesso alle strutture socio-sanitarie. Il contributo si incentra poi sull'istruttoria tecnico-scientifica e la motivazione sulla non manifesta infondatezza delle questioni di legittimità costituzionale aventi ad oggetto la disciplina sull'obbligo vaccinale e sugli aspetti problematici dell'ordinanza di rimessione del CGARS.
