Par l’étude d’un cas – Alphonse Dupront (particulièrement son texte « Itinéraire », in Du sacré. Croisades et pèlerinages. Images et langages) – j’entends éprouver l’hypothèse selon laquelle l’image détermine des modalités inédites du savoir historien. Dupront ne produit pas, sur les images, un discours en surplomb ni un texte où l’image est prétextuelle. Il réalise une expérience : son texte est à la fois le lieu d’une pratique et l’endroit où se réfléchit cette pratique. Le récit de Dupront constitue un métadiscours et c’est par l’image que le récit historien est contraint de s’engager dans l’autoréflexivité. Chez Dupront, les catégories du temps et de l’image sont étroitement intriquées. Cette intrication des catégories vient de ce que la définition du temps (longue durée) engendre une conception de l’événement (le vécu qu’étudie l’historien) s’accordant à une certaine définition de l’image (l’image entendue comme agrégat d’hétérogènes et, par-là, possédant un potentiel d’actualisation). Dès lors, événement et image partagent une même propriété, celle d’être actualisables. Cette contiguïté catégorielle fonde le système dupronien. En cela, l’image occupe une place prépondérante ; elle détermine des modalités inédites du savoir historique et questionne le dispositif historique dans son ensemble. Ainsi, la marge où se tient Dupront révèle quelque chose de fort qui œuvre au sein de la pratique. [less ▲]

Fermentative hydrogen production has often been described as inhibited by its own gas production. In this work, hydrogen production by Clostridium butyricum was investigated in batch Biochemical Hydrogen Potential (BHP) tests and in a 2.5L anaerobic sequenced batch reactor (AnSBR) under different operating conditions regarding liquid-to-gas mass transfer. Through the addition of both stirring up to 400rpm and nitrogen sparging, the yields were enhanced from 1.6 to 3.1molH2molglucose -1 and the maximum hydrogen production rates from 140 to 278mLh-1. These original results were achieved with a pure Clostridium strain. They showed that hydrogen production was improved by a higher liquid-to-gas hydrogen transfer resulting in a lower dissolved hydrogen concentration in the culture medium and therefore in a lower bacterial inhibition. In addition, biohydrogen partitioning between the gas and the liquid phase did not conform to Henry's Law due to critical supersaturation phenomena up to seven-fold higher than the equilibrium conditions. Therefore, dissolved hydrogen concentration should be systematically measured instead of the headspace hydrogen partial pressure. A model was proposed to correlate H2 production yield and rate by the pure C. butyricum strain CWBI1009 with mass transfer coefficient KLa. [less ▲]

This paper deals with data transfer between two meshes as it happens in a finite element context when a remeshing has to be performed. We propose a finite-volume-based data transfer method for an efficient remeshing of three-dimensional solid mechanics problems. The originality of this transfer method stems from a linear reconstruction of the fields to be transferred on an auxiliary finite volume mesh, a fast computation of the transfer operator and the application to the complete remeshing of 3D problems. This procedure is applicable to both nodal values and discrete fields defined at quadrature points. In addition, a data transfer method using mortar elements is presented. The main improvement made to this second method comes from a fast computation of mortar elements. These two data transfer methods are compared with the simplest transfer method, which consists of a classical interpolation. After some academic examples, we present 2D forging and 3D friction stir welding applications. [less ▲]
