Unraveling the exhumation history of high-pressure ophiolites using magnetite (U-Th-Sm)/He thermochronometry

2020

International audience; Magnetite is a ubiquitous oxide in ultramafic and mafic rocks, which is present in a large range of geological and tectonic settings. In the case of high-pressure ultramafic rocks, exhumation timing is commonly constrained by geochronometers in nearby lithologies. The development of the magnetite (U-Th-Sm)/He method (MgHe) has opened new perspectives to refine the exhumation history of such rocks. However no thermal history has been deduced using MgHe data so far. Here we applied MgHe dating to magnetite from an HP-LT alpine ophiolite body (Rocher Blanc) from the Schistes lustres units (Western Alps, France) where part the P-T-t history is constrained to further refi…

Market Determinants of Voluntary Disclosure of Macroeconomic Effects on Corporate Performance

2012

The macroeconomic environment is an important determinant of firm performance. Nevertheless, many firms are simplistic in the approach they use to identify, analyze and create strategies for managing the vital relationship between intrinsic competitiveness and macroeconomic fluctuations. Few firms disclose this information to outside stakeholders, which means they are prevented from understanding the intrinsic performance. We analyze the effects of the implementation/development of IFRS/IAS 1 on voluntary macroeconomic information disclosure with a focus on information content and market determinants. We base our analysis on a sample of the 100 largest public European firms in the period 20…

Determinants of internet‐based corporate governance disclosure by Spanish listed companies

2008

PurposeThe purpose of this paper is to analyse the corporate governance information disclosed by Spanish listed companies on the internet, with the objective of assessing the extent and the influence of several corporate characteristics on the level of information voluntarily disclosed.Design/methodology/approachThe study took as its reference the existing literature on the examination of the quality of web sites and the importance of content as a key variable in determining web site quality. To quantify the corporate governance information disclosed by Spanish listed companies, three transparency indexes were designed. To contrast which variables determine the information provided online, …

Modeling propagation for high-power cylindrical microwave applicators

2001

In this letter, the dispersion characteristics and energy configurations of a cylindrical partially filled waveguide or lossy multilayered rod shielded by a metallic enclosure are presented for several modes. These parameters are obtained by a numerical simulation based on the residues theory. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 30: 192–195, 2001.

On codimension two embeddings up to link-homotopy

2017

We consider knotted annuli in 4-space, called 2-string-links, which are knotted surfaces in codimension two that are naturally related, via closure operations, to both 2-links and 2-torus links. We classify 2-string-links up to link-homotopy by means of a 4-dimensional version of Milnor invariants. The key to our proof is that any 2-string link is link-homotopic to a ribbon one; this allows to use the homotopy classification obtained in the ribbon case by P. Bellingeri and the authors. Along the way, we give a Roseman-type result for immersed surfaces in 4-space. We also discuss the case of ribbon k-string links, for $k\geq 3$.

On the radiative impact of aerosols on photolysis rates: comparison of simulations and observations in the Lampedusa island during the ChArMEx/ADRIME…

2016

The Mediterranean basin is characterized by large concentrations of aerosols from both natural and anthropogenic sources. These aerosols affect tropospheric photochemistry by modulating the photolytic rates. Three simulations of the atmospheric composition at basin scale have been performed with the CHIMERE chemistry-transport model for the period from 6 June to 15 July 2013 covered by the ADRIMED campaign, a campaign of intense measurements in the western Mediterranean basin. One simulation takes into account the radiative effect of the aerosols on photochemistry, the second one does not, and the third one is designed to quantify the model sensitivity to a bias in the ozone column. These s…
