Isolation of polymorphic tetranucleotide microsatellite markers for the grey-headed robin (Poecilodryas albispecularis)

We isolated 12 polymorphic microsatellite markers for the grey-headed robin Poecilodryas albispecularis from genomic libraries enriched for (AAGG)n and (AACC)n repetitive elements and characterized them in 12 individuals. The number of alleles ranges from three to nine per locus with the observed heterozygosity ranging from 0.33 to 0.90. These markers will be useful for analysis of questions concerning population genetic structure and testing models of speciation.

Results of the IEA round Robin on viscosity and aging of fast pyrolysis bio-oils:long-term tests and repeatability

An international round robin study of the viscosity measurements and aging of fast pyrolysis bio-oil has been undertaken recently, and this work is an outgrowth from that effort. Two bio-oil samples were distributed to two laboratories for accelerated aging tests and to three laboratories of long-term aging studies. The accelerated aging test was defined as the change in viscosity of a sealed sample of bio-oil held for 24 h at 80 °C. The test was repeated 10 times over consecutive days to determine the intra-laboratory repeatability of the method. Other bio-oil samples were placed in storage at three temperatures, 21, 5, and -17 °C, for a period of up to 1 year to evaluate the change in viscosity. The variation in the results of the accelerated aging test was shown to be low within a given laboratory. The long-term aging studies showed that storage of a filtered bio-oil under refrigeration can minimize the amount of change in viscosity. The accelerated aging test gave a measure of change similar to that of 6-12 months of storage at room temperature for a filtered bio-oil. Filtration of solids was identified as a key contributor to improving the stability of the bio-oil as expressed by the viscosity based on results of the accelerated aging tests as well as long-term aging studies. Only the filtered bio-oil consistently gave useful results in the accelerated aging and long-term aging studies. The inconsistency suggests that better protocols need to be developed for sampling bio-oils. These results can be helpful in setting standards for use of bio-oil, which is just coming into the marketplace. © 2012 American Chemical Society.

Results of the IEA round robin on viscosity and stability of fast pyrolysis bio-oils

An international round robin study of the stability of fast pyrolysis bio-oil was undertaken. Fifteen laboratories in five different countries contributed. Two bio-oil samples were distributed to the laboratories for stability testing and further analysis. The stability test was defined in a method provided with the bio-oil samples. Viscosity measurement was a key input. The change in viscosity of a sealed sample of bio-oil held for 24 h at 80 °C was the defining element of stability. Subsequent analyses included ultimate analysis, density, moisture, ash, filterable solids, and TAN/pH determination, and gel permeation chromatography. The results showed that kinematic viscosity measurement was more generally conducted and more reproducibly performed versus dynamic viscosity measurement. The variation in the results of the stability test was great and a number of reasons for the variation were identified. The subsequent analyses proved to be at the level of reproducibility, as found in earlier round robins on bio-oil analysis. Clearly, the analyses were more straightforward and reproducible with a bio-oil sample low in filterable solids (0.2%), compared to one with a higher (2%) solids loading. These results can be helpful in setting standards for use of bio-oil, which is just coming into the marketplace. © 2012 American Chemical Society.

An international round-robin calibration protocol for nanoindentation measurements

Nanoindentation has become a common technique for measuring the hardness and elastic-plastic properties of materials, including coatings and thin films. In recent years, different nanoindenter instruments have been commercialised and used for this purpose. Each instrument is equipped with its own analysis software for the derivation of the hardness and reduced Young's modulus from the raw data. These data are mostly analysed through the Oliver and Pharr method. In all cases, the calibration of compliance and area function is mandatory. The present work illustrates and describes a calibration procedure and an approach to raw data analysis carried out for six different nanoindentation instruments through several round-robin experiments. Three different indenters were used, Berkovich, cube corner, spherical, and three standardised reference samples were chosen, hard fused quartz, soft polycarbonate, and sapphire. It was clearly shown that the use of these common procedures consistently limited the hardness and reduced the Young's modulus data spread compared to the same measurements performed using instrument-specific procedures. The following recommendations for nanoindentation calibration must be followed: (a) use only sharp indenters, (b) set an upper cut-off value for the penetration depth below which measurements must be considered unreliable, (c) perform nanoindentation measurements with limited thermal drift, (d) ensure that the load-displacement curves are as smooth as possible, (e) perform stiffness measurements specific to each instrument/indenter couple, (f) use Fq and Sa as calibration reference samples for stiffness and area function determination, (g) use a function, rather than a single value, for the stiffness and (h) adopt a unique protocol and software for raw data analysis in order to limit the data spread related to the instruments (i.e. the level of drift or noise, defects of a given probe) and to make the H and E r data intercomparable. © 2011 Elsevier Ltd.

Plus ça change...Le renouvellement de la tradition chez Régine Robin, Dany Laferrière et Ying Chen

Cette thèse analyse la manifestation de la tradition dans certains textes des écrivains migrants au Québec, nommément La Québécoite et L’Immense fatigue des pierres de Régine Robin, Comment faire l’amour avec un nègre sans se fatiguer, Cette grenade dans la main du jeune nègre est-elle une arme ou un fruit ?, Pays sans chapeau et L’Énigme du retour de Dany Laferrière et, enfin L’Ingratitude et Immobile de Ying Chen. Les références à des récits, à des croyances et à des pratiques collectives qui se trouvent dans ces textes signalent une transformation de la transmission de l’héritage culturel d’une génération à l’autre. Afin de parvenir à une meilleure compréhension des liens entre la mémoire collective et la communauté culturelle se définissant dans le présent, je me sers du travail de folkloristes comme Alan Dundes, Simon Bronner et Richard Handler de même que des théories sur la faculté de la tradition proposées par Paul Ricœur, Walter Benjamin et Pierre Nora. Dans la première partie de la thèse, j’étudie l’imaginaire populaire du XIXe siècle et son incorporation dans la littérature canadienne-française de l’époque. Ensuite, j’analyse la remise en question de la tradition – de même que le rôle sous-jacent qu’elle continue de jouer, lors de la Révolution tranquille. Par rapport à ces deux périodes précédentes, l’usage du folklore chez les auteurs migrants laisse présager une nouvelle opération de la tradition dans un contexte où plusieurs groupes culturels se rencontrent. Dans un contexte pluraliste, l’idée de la communauté culturelle est fabriquée en fonction de notre appartenance à plusieurs groupes. Je m’intéresse à comment les gens qui habitent ensemble formulent des liens au passé même dans une situation dans laquelle ils ne partagent pas les mêmes rapports à la mémoire collective. Explorant le renouvellement, qui peut sembler paradoxal, de la tradition, je forme l’hypothèse qu’il est possible pour un groupe de se définir en fonction de valeurs culturelles puisées dans un passé collectif qui s’adaptent constamment à la réalité actuelle.
