Perdre le fil: labyrinthes de la littérature française moderne

2009

From the day when Theseus killed the Minotaur, the Maze turned into a form in search of meaning, and became useless. As a result, one was enjoined to ascribe nw meanings to the empty strcuture. Modern writers, when confronted with such a void, will have explored all its possibilities: while some of them, like Michel Butor, dismiss the sacred dimensions, others, like Serge Doubrovsky, see in it the image of the self (the body, the psyche...), and others still, like Raymond Roussel, Alain Robbe-Grillet or Georges Pererc, make of the pure geometrical structure of the labyrinth an aesthetic model, and thus a mirror of the work of art. However, one still have to ask whether the labrinth is a val…

ESR response to gamma-rays of alanine pellets containing B(OH)3 or Gd2O3.

2007

ESR response to gamma-irradiation (1-50 Gy) of blends containing alanine and either B(OH)(3) or Gd(2)O(3) is reported. The sensitivity of the alanine--B(OH)(3) blend is comparable to the sensitivity of pure alanine, although its lowest detectable dose, LDD, is smaller ( approximately 1.3 Gy) than that of pure alanine ( approximately 2.9 Gy). Alanine with Gd(2)O(3) is about two times more sensitive than pure alanine, and its LDD is 0.8 Gy. The better sensitivity and LDD are probably due to the high atomic number (Z=64) of gadolinium, which enhances the interaction probability with photons and, consequently, the radical yield. This study suggests that other high-Z atoms may be useful for incr…

Comparison of EPR response of alanine and Gd2O3-alanine dosimeters exposed to TRIGA Mainz reactor.

2015

In this work we report some preliminary results regarding the analysis of electron paramagnetic resonance (EPR) response of alanine pellets and alanine pellets added with gadolinium used for dosimetry at the TRIGA research reactor in Mainz, Germany. Two set-ups were evaluated: irradiation inside PMMA phantom and irradiation inside boric acid phantom. We observed that the presence of Gd2O3 inside alanine pellets increases the EPR signal by a factor of 3.45 and 1.24 in case of PMMA and boric acid phantoms, respectively. We can conclude that in the case of neutron beam with a predominant thermal neutron component the addition of gadolinium oxide can significantly improve neutron sensitivity of…

La statue de Millet sur l'oppidum, entre mythe et réalité

2020

La statue colossale de Vercingétorix, érigée sur la partie la plus haute de l’oppidum d’Alésia, est la plus célèbre et la plus importante des représentations du chef valeureux – mais vaincu – des armées gauloises. L’image de sa défaite pleine de panache dans les manuels scolaires aura marqué pendant plus d’un siècle nos esprits d’enfants.

Selling a vote

2005

Abstract A voting function is a rule that determines the outcome of an election: taking the voters' votes as input, a voting function selects the winning candidate from the set of candidates receiving some vote. A voting function is immune to vote selling when, given that neither voter i nor voter j votes for the winning candidate, a change ceteris paribus in i's vote cannot make the candidate for which j votes the winner. It is shown that voting functions immune to vote selling have either a dictator (a voter who always determines the winning candidate) or a dictated candidate (a candidate who becomes the winner by just receiving some vote).

The combined impact of cold smoking and natural antioxidants on quality and shelf life of dolphinfish (Coryphaena hippurus) fillets

2019

This study aimed to produce new value-added products from dolphinfish (Coryphaena hippurus) as fillets when using cold smoking combined with natural antioxidants, obtained from Halocnemum strobilaceum a plant belonging to halophytes. The fillet treatments were controlled (untreated), immersed in standard brine (STD), treated with NaCI and antioxidant before freezing (Aox-pre) and treated with NaCl and antioxidant after thawing (Aox-post). The quality of dolphinfish fillets was assessed using sensory, biochemical, microbiological, and technological parameters. Treating fillets with antioxidants before freezing and cold smoking (Aox-pre) enhanced significantly the shelf life, as well as impro…

Arsenic(III) Removal at Low Concentrations by Biosorption usingPhanerochaete chrysosporiumPellets

2013

As(III) removal from dilute aqueous solutions by biosorption onto pellets of the white rot fungus Phanerochaete chrysosporium was investigated. The As(III) uptake capacity was evaluated at low initial concentrations (0.2–1 mg/L) which revealed that the P. chrysosporium pellets were only slightly less efficient than the well studied adsorbent granular ferric hydroxide. Moreover, its performance was much more superior compared to anaerobic granular sludge, another cheaply available bacterial biosorbent. In the studied pH (5–9) and biomass concentration (0.25–1.5 g/L wet weight basis) ranges, no large differences in As(III) removal efficiency were observed. The influence of different ions, com…

Discovery of indigoid-containing clay pellets from La Blanca: significance with regard to the preparation and use of Maya Blue

2014

Analytical studies using extraction/liquid chromatography, pyrolysis–silylation gas chromatography–mass spectrometry, visible and infrared spectroscopies, solid state voltammetry and electron microscopy on a set of spherical greenish pellets discovered in the Structure 4H1 of the ancient Maya site of La Blanca (Peten Department, Guatemala), dated in the Terminal Classic period, confirm the presence of indigoids (dehydroindigo, indigo) associated to palygorskite. The appearance of such pieces, whose origin and function is uncertain, but most likely correspond to residuals of a decorative plaster, can be considered as indicative of the use of Maya Blue in a quotidian context, thus suggesting …
