Cet article porte sur l’efficacité politique d’une série photographique qui problématise des questions socioculturelles contemporaines telles l’immigration, l’exploitation et l’éthique du travail. L’image photographique devient une ressource dans les mains des acteurs sociaux et fait fonction de diagnostic des tensions du contemporain. La photographie permet de «reconnaître à travers» (c’est-à-dire « diagnostiquer ») et de formuler des jugements. Le potentiel sémantique du diagnostic engendré par cette série et la force illocutoire des jugements qui y sont inscrits fonctionnent comme une sorte d’« argumentation par images ». L’analyse de cette série photographique, réalisée par le photographe et théoricien Allan Sekula, nous a amené à nous interroger sur la relation entre image, corpus, genres d’afférence et statuts (documentaire et artistique).

The size dependence of the ferroelectric properties of BaTiO3 nanowires is studied from first principles. We show that the ferroelectric distortion along the wire axis disappears below a critical diameter of about 1.2 nm. This disappearance is related to a global contraction of the unit cell resulting from low atomic coordinations at the wire surface. It is shown that a ferroelectric distortion can be recovered under appropriate tensile strain conditions. (c) 2006 American Institute of Physics. [less ▲]

Concurrently to research conducted on ordinary Portland cement (PC), new types of binders were developed during the last decades. These are formed by alkali-activation of metakaolin or ground-granulated blast furnace slag (GGBFS) and are named, respectively, geopolymers (GP) or alkali-activated slag (AAS). Four different cementitious materials were synthesised: PC, AAS, GP, and a mix GP-AAS and fully compared about their compositions and (micro)-structures. X-ray diffraction has revealed the presence of semi-crystalline C-S-H gel binding phase in PC while AAS, GP and GP-AAS are nearly amorphous. Progressive structural changes have been observed between the different samples by means of infrared spectroscopy, Si-29 and At-27 magic-angle-spinning nuclear magnetic resonance spectroscopy: there is a polymerisation extent of the (alumino)-silicate framework from PC [SiQ(1) and SiQ(2) units] to AAS [SiQ(2) and SiQ(2)(1Al) units] and finally to GP [SiQ(4)(2Al) and SiQ(4)(3Al) units]. Scanning electron microscopy has shown that GP is a homogeneous matrix while the other materials are composites containing GGBFS grains surrounded by a binding matrix. Energy dispersive X-ray EDX analyses (line scans) have shown the absence of formation of any specific phase at the matrix-grains interfaces. (c) 2006 Elsevier Ltd. All rights reserved. [less ▲]

The chemical compound Na(Na,Mn)(7)Mn-22(PO4)(18)center dot 0.5H(2)O was synthesized with a Tuttle pressure vessel at 800 degrees C and 1 kbar during experimental investigations on the conditions of fillowite formation. The crystal structure of a single-crystal, space group R (No. 148), a = 15.2741(9), c = 43.334(3) angstrom, Z = 6, was determined from X-ray intensity data and refined up to R-1 = 0.0728 and R-l{FO > 4 sigma(FO)} = 0.0546. The crystal structure of Na(Na,Mn)(7)Mn-22(PO4)(18)center dot 0.5H(2)O is similar to the structure of fillowite, Na6Ca3(Mn,Fe)(21)(PO4)(18.), but a significant difference between the synthetic H2O containing compound and fillowite is the replacement of (Na12)O-8(-) by Mn(H2O)(2)O-5(-) polyhedra, which form characteristic six-member rings. The coordination polyhedra around Na12 and Mn12 are so different that simple isomorphous substitution of Na12 by Mn12 is very unlikely, but whole six-member rings either of (Na12)O-8(-) or (Mn12)(H2O)(2)O-5 polyhedra seem to be distributed statistically over the crystal structure. No indication for ordering, e.g. sheet by sheet, has been observed. Na(Na,Mn)(7)Mn-22(PO4)(18)center dot 0.5H(2)O is the first fillowite-like compound for which water is located in the structure from single-crystal study. This result is proved by infrared spectral data and indicates that water can play an essential role in the fillowite structure-type. Structural features of the synthetic compounds Na(Na,Mn)(7)Mn-22(PO4)(18)center dot 0.5H(2)O, Na4Ca4Mg21(PO4)(18) and fillowite are compared. [less ▲]

The objective of the present study was to assess the validity of barometric whole-body plethysmography (BWBP), to establish reference values, and to standardise a bronchoprovocative test to investigate airway responsiveness using BWBP in healthy dogs. BWBP measurements were obtained from six healthy beagle dogs using different protocols: (1) during three consecutive periods (3.5 min each) in two morning and two evening sessions; (2) before and after administration of two protocols of sedation; (3) before and after nebulisation of saline and increasing concentrations of carbachol and histamine both in conscious dogs and in dogs under both protocols of sedation. Enhanced pause (PENH) was used as index of bronchoconstriction. Basal BWBP measurements were also obtained in 22 healthy dogs of different breeds, age and weight. No significant influence of either time spent in the chamber or daytime was found for most respiratory variables but a significant dog effect was detected for most variables. A significant body weight effect was found on tidal volume and peak flow values (P < 0.05). Response to carbachol was not reproducible and always associated with side effects. Nebulisation of histamine induced a significant increase in respiratory rate, peak expiratory flow, peak expiratory flow/peak inspiratory flow ratio and PENH (P < 0.05). The response was reproduced in each dog at different concentrations of histamine. Sedation with acepromazine + buprenorphine had little influence on basal measurements and did not change the results of histamine challenge. It was concluded that BWBP is a safe, non invasive and reliable technique of investigation of lung function in dogs which provides new opportunities to characterise respiratory status, to evaluate airway hyperresponsiveness and to assess therapeutic interventions.

Le transport de la charge de fond de plusieurs rivières du massif ardennais (Belgique) a été analysé grâce à différentes techniques de marquage de galets (peinture, charge métallique, émetteurs radio). Ces rivières possèdent un bassin versant dont la taille est comprise entre 0,3 et 2700 km². Les observations ont permis de mettre en évidence le débit à partir duquel débute le charriage. Pour des rivières importantes (bassin versant supérieur à 500 km²), cette mise en mouvement se produit pour des débits légèrement inférieurs au débit à plein bord (0,7 à 1 Qb), débits qui se présentent en moyenne 5 à 11 jours par an. Dans les rivières ardennaises de taille intermédiaire (bassin versant compris entre 100 et 500 km²), on constate que le charriage débute pour un débit proche de 0,5 fois le débit à plein bord, avec des récurrences de l’ordre de 0,3 an et une durée de charriage variant entre 8 et 12 jours par an. Dans les rivières de dimension modeste (bassin versant inférieur à 100 km²), il apparaît que la mise en mouvement de la charge de fond se produit pour des débits compris entre 0,5 et 0,8 Qb, mais la récurrence de ces débits est relativement faible et le charriage peut se produire jusqu’à 20 jours par an. Par ailleurs, le transport solide par charriage a été évalué à l'aide de pièges à sédiments dans les rivières de petite dimension (bassin versant inférieur à 10 km²) ; il est relativement peu important dans les bassins forestiers (de l'ordre de 0,5 t.km-².an-1), notamment en raison de la multiplication des embâcles végétaux qui accroissent la rugosité et provoquent une forte dissipation d'énergie. Dans les rivières plus importantes, le transport solide a été estimé entre 0,4 et 2,5 t.km-².an-1 grâce à l'analyse des quantités curées systématiquement aux mêmes sites et à la réalisation de levés topographiques de contrôle. Nous avons ensuite analysé l’évolution des quantités charriées en fonction de la puissance spécifique au plein bord développée par ces rivières. La relation établie sur la base de ces données a permis de mettre en évidence le déficit en sédiments de certaines rivières ainsi que plusieurs facteurs influençant le charriage. [less ▲]
