Adsorption of Eu(III) onto Minerals in the Presence of Humic Acids: Effects of Various Solution Parameters and Sorptive Fractionation on Modelling and Spectroscopy
No full textInternational audienceAdsorption of metals on minerals with humic acids is always under predicted [1]. The case of Eu(III) in ternary system including purified Aldrich humic acid (PAHA) and alpha-Al2O3 was measured, modelled and probed using time-resolved laser-induced luminescence spectroscopy (TRLS). Each binary system was studied independently [2,3,4], and the luminescence properties of Eu(III), luminescence spectra and decay times (%), were aquired and compared [5]. Influence of ionic strength and PAHA concentration was also evaluated.The typical luminescence behaviour of Eu(III)-HA system, showing a bi-exponential decay, was also found in the ternary system Eu(III)/PAHA/'- Al2O3, but with marked differences. Luminescence spectra and faster decay %1 are the same in both system at pH 6, modifications of Eu(III) luminescence spectra and decrease of %2 are showing a progressive influence of '-Al2O3. The non-variation of %1suggests the on-going influence of PAHA, notwithstanding its progressive desorption. Comparing with previous data on sorptive fractionation of PAHA [2,3,6], and with the TRLS evolution of the system [5], an operational modelling was proposed [4], which implies that alumina-sorbed PAHA is showing a stronger interaction towards Eu(III) compared with non-sorbed PAHA even at pH > 7. This stronger interaction is due to the sorptive fractionation which reveals stronger binding sites [1,4,7]. [1] Reiller (2012) Miner.

Samuel Beckett and the Writers of Port-Royal
Get PDFIt has been observed that ‘the literary influences on Beckett have been far more important than has been acknowledged, and more important indeed, than the philosophical influences’ (Smith 2002: 3). The truth of this statement is evidenced by the description that scholars have given of Samuel Beckett’s relationship to seventeenth century French classicism. To date, critical interest has been limited for the most part to the figure of the philosopher René Descartes on the (fragile) grounds that Beckett was exclusively concerned with the Cartesian imperative of clarity and order, the fundamental dualism between body and mind, and Nominalism.
Together with the assumption that Beckett’s vision was essentially Cartesian, his literary filiation with Pascal was suggested by critics, but only in terms of Beckett’s formal approach to the theatre. In his short article on En attendant Godot in 1953, the playwright Jean Anouilh was among the first reviewers to suggest that Beckett’s drama synthesizes the encounter between ‘classicism’ and a ‘modern’ form of art. It is well known that Beckett retained a lifelong admiration for Pascal – indeed, Pascal was one of his ‘old chestnuts’ (Knowlson 1997: 653). Little attention has been paid, however, to the originality of Pascal’s thought, the specific nature of his prose, and the impact these might have had upon Beckett’s mature work, especially the trilogy and the subsequent short prose. Yet, in the literary and philosophical context of post-war France, Beckett’s filiation with Pascal, their corresponding preoccupations, were evident to his contemporaries, who identified Pascal as an underlying presence in his works
Study of CaUO(CO) complexes using CE-ICP-MS with polyetheretherketone (PEEK) capillaries
No full textInternational audienceThe formation constants of CaUO(CO) complexes were determined directly using capillary electrophoresis coupled with inductively coupled plasma mass spectrometry (CE-ICP-MS) in 0.1 M NaCl and at room temperature. Instead of conventional fused silica, polyetheretherketone (PEEK), a neutral organic material, was used as the capillary material to avoid interactions between uranyl and silica. Since PEEK is not optically transparent, a macrocyclic neutral complex, Ga-NOTA, was used to measure the electroosmotic flux directly by ICP-MS. The impact of the Joule effect was evaluated to control the temperature during electrophoresis. To alter the reversible interaction that arose from continuous use, a two-mode electrophoresis strategy was adopted. The observed mobilities of the samples showed a satisfactory correlation with the theoretical charge calculated from previous data (C. Shang and P. E. Reiller, Dalton Trans., 2020, 49, 466–481). The successive formation constants obtained in this work, log K(CaUO(CO)) = 5.28 ± 0.39 and log K(CaUO(CO)(aq)) = 8.46 ± 0.67 in 0.1 M NaCl, were extrapolated to infinite dilution using the Davies equation, yielding log β°(CaUO(CO)) = 27.12 ± 0.39 and log β°(CaUO(CO)(aq)) = 30.30 ± 0.67. These values are in excellent agreement with Shang and Reiller (C. Shang and P. E. Reiller, Dalton Trans., 2020, 49, 466–481). This further verifies the thermodynamic data available for these species and validates PEEK-based capillary electrophoresis for the measurement of thermodynamic constants of inorganic complexes in alkaline media

First person - Aude Pascal
No full textInternational audienceFirst Person is a series of interviews with the first authors of a selection of papers published in Journal of Cell Science, helping early-career researchers promote themselves alongside their papers. Aude Pascal is first author on `Annexin A2 and Ahnak control cortical NuMA-dynein localization and mitotic spindle orientation', published in JCS. Aude is a research assistant in the lab of Re ' gis Giet at University of Rennes, France, who is particularly interested in developmental biology. She has always been struck by the fact that a whole organism displaying multiple functions arises from a single cell. For this reason, she has oriented her research on mitosis and meiosis to study the different steps, components and structures involved in these processes
Pascal Tutorial, 1987
Get PDFThere exists a limited number of tutorials for the Pascal programming language using the Apple Computer. The demand for these tutorials exceeds the supply. In this thesis an attempt was made to rectify this shortage by designing a Pascal tutorial for the Apple computer. This Pascal tutorial is designed to assist with instructing an introductory computer programming course in Pascal, incorporating Apple Superpilot as the authoring language. Emphasis is placed on making the program "user friendly." A person with no previous programming experience should be able to easily execute this tutorial. The information presented as the subject matter of the tutorial will follow the guidelines recommended by the Association for Computing Machinery
