We present here three expression plasmids for Trypanosoma cruzi adapted to the Gateway® recombination cloning system. Two of these plasmids were designed to express trypanosomal proteins fused to a double tag for tandem affinity purification (TAPtag). The TAPtag and Gateway® cassette were introduced into an episomal (pTEX) and an integrative (pTREX) plasmid. Both plasmids were assayed by introducing green fluorescent protein (GFP) by recombination and the integrity of the double-tagged protein was determined by western blotting and immunofluorescence microscopy. The third Gateway adapted vector assayed was the inducible pTcINDEX. When tested with GFP, pTcINDEX-GW showed a good response to tetracycline, being less leaky than its precursor (pTcINDEX).

Granitic and mafic magma pulses were sequentially accreted in the spectacularly exposed shallow crustal Torres del Paine laccolith, in southern Patagonia. This 12.5 Ma pluton forms a composite intrusion with a subvertical feeding system in the west and a laccolith in the east. A key unknown in the formation of sill complexes is how individual magma pulses are assembled over time and the geometry and localization of their feeding system. High resolution zircon CA-ID-TIMS U-Pb dating shows that the laccolith grew first by under-accretion of granitic sills over 90 +/- 30 ka, linked to a `sheet-like' feeding system, followed by underplating of mafic sills after similar to 20 ka of quiescence. In the mafic sills complex, individual sills were injected by over-accretion during 41 +/- 11 ka. Our data show that successive granitic and mafic magmas emplacement generated a volume of similar to 88 km(3) in 162 +/- 11 ka. (C) 2012 Elsevier B.V. All rights reserved.

Cette recherche teste l'hypothèse de l'intervention d'un biais de confirmation d'hypothèse dans la procédure actuelle de construction des questionnaires d'internalité. Dans une étude pilote, 18 étudiants ont produit des explications en vue de la construction d'un questionnaire d'internalité soit en ayant connaissance de l'existence d'une norme d'internalité vs d'une norme d'externalité, soit sans activation expérimentale de cette connaissance (condition "contrôle"). Dans une première étude, 32 étudiants ont évalué le lieu de causalité et la plausibilité des explications produites dans l'étude pilote. Dans une seconde étude, 113 étudiants ont évalué la valeur sociale de ces explications internes et externes dans une situation de recrutement. Les résultats indiquent tout d'abord que le biais de confirmation influence les individus lorsqu'ils sont amenés à produire des explications internes et externes. On observe ainsi que la différence en faveur des explications internes sur la plausibilité (étude 1) et sur la valeur sociale (étude 2) est plus marquée en condition "norme d'internalité" qu'en condition "contrôle", et plus dans cette dernière condition que dans la condition "norme d'externalité". De plus, les résultats obtenus dans la condition "contrôle" suggèrent que les explications internes sont plus plausibles (étude 1) et plus valorisées que les explications externes (étude 2). Ainsi, si cette recherche confirme l'impact du biais de confirmation d'hypothèse, elle suggère également l'existence d'une norme d'internalité dans la pensée sociale.

The EU has been one of the main actors involved in the construction process of an international climate change regime, adopting it as an identity sign in the international arena. This activism has reverted in the European political agenda and in the one of its Members States. Therefore, climate change has become a driver for the EU growing participation in energy policy and for its governance evolution. In this context, much attention has been paid to the climate and energy policies integration agreed after the 2007 spring European Council. Apparently, this decision meant a decisive step towards the incorporation of the environmental variable in the energy policy-making. Moreover, the Action Plan [2007-2009] “Energy Policy for Europe” outlined priority actions in a variety of energy-related areas, implying the new European Energy Policy commencement. Against this background, there is still much left to understand about its formulation and its further development. Rooted on the Environmental Policy Integration approach, this paper traces the increasing proximity between environment and energy policies in order to understand the green contribution to the European Energy Policy construction.

The Plateforme Interdisciplinaire of the University of Lausanne is at the crossroad of soft and hard sciences. We question the place and the role of languages and scientific cultures in the construction and the transmission of knowledge. The examples - from the fields of law, health, mathematics, neurosciences and university education - exceed a conception of languages as transparent vehicles for ideas and discoveries. They enable to consider the diversity of languages and scientific cultures as a mean for a " thick standardization" of science, integrating and valuing the double need for conceptual depth and accessibility of scientific discourse.

The objective of this project consists of designing and constructing a RTM mould for a loose flange of glass fibre reinforced plastic (GRP). The design phase has the mission to realise a quality and simple design of the RTM mould, with the objective to obtain an easy and economic phase of construction and the more possible great characteristics of the loose flange. In fact this RTM mould will be a mould prototype, which will be developed in the future to obtain an RTM mould able to support a loose flange production. Therefore when more steps are developed in this project, then the future objective will be near
