U-Pb age constraints on Carboniferous-Permian French continental basins - implications for their depositional history and correlations with European …

2022

International audience; Late Carboniferous to Permian basins of western Europe (~Gzhelian to Artinskian), developed during thelate stages of the Variscan orogeny in equatorial paleolatitudes. The stratigraphic context of most of thesebasins remains poorly constrained, because mainly based on “continental stages” (e.g., Stephanian, Autunian,Saxonian and Thuringian) that are diachronous. Therefore, correlating these basins together and withinternationally recognized stratigraphic marine stages requires precise radiochronologic ages.To the south of the Paris Basin (France), volcanic ash-fall layers (i.e., tonsteins) are interbedded in theCarboniferous-Permian sedimentary successions of the Aum…

La présence de l’Etat dans l’Est du diocèse des Gaules au IVe s. : au miroir des sources matérielles et écrites

2021

Der vorliegende Artikel schlägt eine Synthese der Präsenz des Staates in Ostgallien vor. Er beschränkt sich auf das 4. Jh. von der Tetrarchie bis in die theodosianische Zeit. Er stützt sich auf eine kritische und fachübergreifende Betrachtung der materiellen und schriftlichen Dokumentation, die insbesondere bemüht ist, die Daten in Form von Karten zu präsentieren.

Quantification of land-atmosphere exchanges of water, energy and carbon dioxide in space and time over the heterogeneous Barrax site

2008

International audience; To advance our understanding of land-atmosphere exchanges of water, energy and carbon dioxide (CO2) in space and time over heterogeneous land surfaces, two intensive field campaigns were carried out at the Barrax agricultural test site in Spain during 12-21 July 2004 (SPARC 2004) and 8-14 July 2005 (SEN2FLEX 2005) involving multiple field, satellite and airborne instruments for characterizing the state of the atmosphere, the vegetation and the soil from the visible to the microwave range of the spectrum. Part of the experimental area is a core site of area 25 km2, within which numerous crops are grown, on both irrigated and dry land, alongside fields of bare soil. Th…

The inhomogeneous mechanical behaviour of Ascending Thoracic Aortic Aneurism (ATAA)

2017

Surgical management of ascending thoracic aortic aneurysms (aTAAs) relies on maximum diameter, growth rate, and presence of connective tissue disorders. The surgical decision however is often not considering that dissection and rupture do occur in patients who do not meet criteria for surgical repair [1,2]. In this study the authors aim to investigate the mechanical properties of aTAAs to be implemented in computational biomechanics models for a preclinical risk evaluation. Additionally, in some recent studies, some data about the biomechanical properties of the aTAAs have been reported [3], but without any relation to bicuspidal or tricuspidal aTAA. The aim of this study was to investigate…

Remarks on the History of the Navy of the Empire of Nicaea in the Light of the Chronicle of Georgios Akropolites

2016

The Empire of Nicaea was a successor of the Byzantium shattered in 1204. In the newly established state marine traditions of Byzantines, remain alive. The best testimony to this, are the evidence contained in the chronicle of Georgios Akropolites, devoted to activities of the rulers of Nicaea, aimed to build their own naval forces. In this paper I'll also try to answer, where was beating the heart of the Nicean shipbuilding industry and how large was the navy of this state. This is important from point of view of the maritime history, because of the fleet of the Empire of Nicaea, filled the gap created after the fall of Constantinople and the Byzantine Empire, which was the local naval powe…

Chimney and Periscope Grafts Observed Over 2 Years After Their Use to Revascularize 169 Renovisceral Branches in 77 Patients With Complex Aortic Aneu…

2013

Purpose: To evaluate the performance of periscope and/or chimney grafts (CPGs) in the endovascular treatment of pararenal or thoracoabdominal aneurysms using off-the-shelf devices. Methods: Between February 2002 and August 2012, 77 consecutive patients (62 men; mean age 7369 years) suffering from pararenal aortic (n¼55), thoracoabdominal (n¼16), or arch to visceral artery aneurysms (n¼6) were treated with aortic stent-graft implantation requiring chimney and/or periscope grafts to maintain side branch perfusion. CPGs were planned in advance and were not used as bailout. A standardized follow-up protocol including computed tomographic angiography, laboratory testing, and clinical examination…
