Glycine ethyl ester was recruited in an amine exchange process based on a transamination to afford ethyl 4H-1,2,4-triazol-4-yl-acetate (L1). The acid hydrolysis of this molecule leads to quantitative isolation of 4H-1,2,4-triazol-4-yl acetic acid (L2). This versatile synthon crystallizes in a noncentrosymmetric orthorhombic space group (Fdd2) with Z = 16. This crystal structure is the first one for a 1,2,4-triazole ligand constructed from an amino acid derivative. The strong intermolecular hydrogen bonding O-HN (2.570(3)Å) connects molecules into infinite one-dimensional chains running parallel to the b axis, and the structure is further extended by numerous but moderate strength hydrogen bonds (C-HO). Prominent features of L2 are the presence of diverse potential coordinating groups such as carboxylic acid and triazole on the same framework as well as the inherent flexibility of the ligand backbone. Reaction of L1 or L2 with aq. Cu(BF 4) 2 in aq. DMF gives dark blue crystals which crystallize in a noncentrosymmetric, cubic space group (I4̌3m) and which were formulated as [Cu 3(μ 3-O)(L2) 3(H 2O) 3]BF 4H 2O (C1). The self-assembly of C 3-symmetric, μ 3-oxo bridged triangular tricopper secondary building blocks (SBB) formed an unique architecture which encompasses voluminous nanoball voids of 1 nm. The total solvent accessible volume is 4477.5 Å 3 which accounts for 48% of the cell volume. The crystal network stability was studied by thermogravimetric analysis (TGA)'differential thermal analysis (DTA) and scanning electron microscopy (SEM) analyses. Sorption properties and gas storage capacities were measured by BET. C1 shows no preference for N 2(g), but a reversible H 2(g) uptake of 21 cm 3/g was observed. Morphology analysis by SEM on single crystals of C1 shows "ultrawellś of square shape irregularly located on the surface, whose origin is due to desolvation or crystal defects. Mercury porosimetry measurements reveal pore size distribution with a diameter ranging from 350 nm to 2.3 μm © 2010 American Chemical Society. [less ▲]

In divided societies, such as Belgium and Canada, the federal principle and consociational power-sharing have been implemented in order to accommodate ethno-linguistic communities. The combination of Daniel Elazar’s seminal work on federalism in plural societies and of Arend Lijphart’s on consociationalism offers a theoretical framework which can be usefully applied to study the distribution of power between the two main ethno-linguistic communities at the highest level of the state. Using the existing “model of points” and the author’s own “model of the weight of ministerial portfolios”, this paper explores the linguistic composition of the federal governments in both countries over the last thirty years (1970-2006). Whereas the Belgian Constitution has required since 1970 that the federal cabinet be staffed by an equal number of Flemish and Francophone ministers, the Canadian Constitution does not require such a linguistic parity and therefore leaves a greater freedom for the composition of the government. On this background, two logics may explain the linguistic composition in the two cases: a logic of transaction between the two main communities and a logic of representation. The paper opens, on the one hand, with the elaboration of the theoretical framework combining the works of Elazar and Lijphart and, on the other hand, with the construction of the two models. The framework and the models are applied to each case, emphasizing the logic of transaction and the logic of representation. On the basis of this examination, this paper concludes by suggesting that Flemish and Francophone Belgians as well and English and French Canadians benefit from the composition of the federal cabinet. The conclusion opens—new—ways and means to hinder political tensions in plural societies through the institutional arrangement. [less ▲]

The first work package of our programme of work is a quantitative overview of the varying incidence of soft densification across England emphasizing outcomes in the period between 2001 and 2011. Its aim is to introduce the policy framework which allowed or encouraged soft densification, to explore its relationship to underlying associated variation in physical and economic conditions, and to suggest the broad contours of its socio-economic effects. In addition to its principal role of providing a framework helping to guide subsequent more detailed examinations, this body of work seeks to address a series of questions close to PUCA's key concerns: · within a policy framework conducive to soft densification, what is the extent of its contribution to the flow of additional dwelling units? · under such a regime, what influences variation in the scale of that contribution from place to place? · and finally, what needs are met by the units generated by soft densification, and what are the associated changes in the social and demographic composition of neighbourhoods?

This report is the second phase of research into the English Experience of Soft Densification and builds upon the quantitative data analysis undertaken in phase I. Adopting an intensive qualitative case study approach two local authorities, the London Borough of Ealing and Bristol City Council, are considered in detail. Ealing represents a suburban area that experienced concurrently significant soft densification and de-conversion of existing stock in the period 2001 to 2011, whilst Bristol over the same period experienced a high level of housing growth.

Apprendre à lire dans une langue n’interfère pas avec l’apprentissage de la lecture dans une autre langue mais prépare plutôt le terrain pour apprendre à lire dans une autre langue. Comme dans le langage oral, il peut y avoir quelques « mixing » de prononciation au niveau des mots qui disparaissent progressivement au fur et à mesure que les langues se compartimentalisent. Avec le temps, l’enfant apprendra également que des mots qui s’écrivent de la même manière dans les deux langues peuvent se prononcer de manière différente. Une recherche menée sur des enfants francophones Belges suivant un programme d’immersion scolaire en anglais et ayant appris à lire en anglais confirment ces observations. 150 enfants âgés de 7 à 12 ans fréquentant ce programme ont été testés sur leurs compétences en lecture du français (décodage et compréhension). Leurs performances (type et nombre d’erreurs, vitesse de lecture) ont été comparées à celles d’enfants francophones fréquentant un enseignement unilingue. Leurs habiletés métaphonologiques (manipulation de la rime et du phonème) ont également été testées. [less ▲]

Elle s’attache à comprendre comment et pourquoi autant de Français, souvent en poste dans l’administration française à Milan, ont commandé des copies du chef-d’œuvre du maître italien, définissant de ce fait les mécanismes de l’engouement pour la peinture murale à la cour de France, sous les règnes de Louis XII et de François Ier.

Le Sélénium (Se) est un oligo-élément indispensable au bon fonctionnement de l'organisme, notamment chez le bovin. Différents éléments plaident pour l’existence de déficits en Se dans le cheptel bovin et particulièrement dans les troupeaux allaitants. Solutions injectables, bolus, supplémentation des rations… différentes méthodes permettent d’assurer un statut en Se correct chez l’animal. Une autre alternative consiste à enrichir les aliments produits au niveau de l’exploitation en utilisant des engrais enrichis en Se. Le Service de Nutrition de la Faculté de Médecine Vétérinaire a testé l’effet de ce type d’engrais sur la teneur en Se dans les aliments produits et sur le statut Se d’un troupeau de vaches allaitantes [less ▲]
