This paper introduces new supporting tools in the field of distant collaborative design, namely DCDS and CRTI-weB. These prototypes respectively support: the early stages of design, through the support of the crucial initial step of free-hand sketches shared in real-time, and the asynchronous collaborative activities. The main goal of this paper is to propose the use of these innovative tools as an efficient and realistic way of managing long distance collaboration, to effectively serve the designers’ needs. This proposition is analyzed and questioned through a real-size experiment featuring 30 architecture and architectural-engineering students, working together in real-time in different locations (Belgium and France). This experiment and the necessary survey open up interesting fields of investigation, such as the relevance of the proposed devices in supporting distant collaborative design in architecture and the benefit this represents for students to merge the IT aspects and the design studio. The methodology and the replicability are analyzed to increase the level and quality of formation of our students and, finally, a critique of the tools confirms a benefit for the developing teams.

Here, we report the sequence characterization of the bovine pseudoautosomal boundary (PAB) and its neighborhood. We demonstrate that it maps to the 5' end of the GPR143 gene, which has concomitantly lost upstream noncoding exons on the Y chromosome. We show that the bovine PAB was created approximately 20.7 million years ago by illegitimate intrachromatid recombination between inverted, ruminant-specific Bov-tA repeats. Accordingly, we demonstrate that cattle share their PAB with all other examined ruminants including sheep, but not with cetaceans or more distantly related mammals. We provide evidence that, since its creation, the ancestral ruminant PAB has been displaced by attrition, which occurs at variable rates in different species, and that it is capable of retreat by attrition erasure. We have estimated the ratio of male to female mutation rates in the Bovidae family as approximately 1.7, and we provide evidence that the mutation rate is higher in the recombining pseudoautosomal region than in the adjacent, nonrecombining gonosome-specific sequences.

In photosynthetic eukaryotes, nonphotochemical plastoquinone (PQ) reduction is important for the regulation of photosynthetic electron flow. In green microalgae where this process has been demonstrated, the chloroplastic enzyme that catalyses nonphotochemical PQ reduction has not been identified yet. Here, we show by an RNA interference (RNAi) approach that the NDA2 gene, belonging to a type II NAD(P)H dehydrogenases family in the green microalga Chlamydomonas reinhardtii, encodes a chloroplastic dehydrogenase that functions to reduce PQ nonphotochemically in this alga. Using a specific antibody, we show that the Nda2 protein is localized in chloroplasts of wild-type cells and is absent in two Nda2-RNAi cell lines. In both mutant cell lines, nonphotochemical PQ reduction is severely affected, as indicated by altered chlorophyll fluorescence transients after saturating illumination. Compared with wild type, change in light excitation distribution between photosystems ('state transition') upon inhibition of mitochondrial electron transport is strongly impaired in transformed cells because of inefficient PQ reduction. Furthermore, the amount of hydrogen produced by Nda2-RNAi cells under sulfur deprivation is substantially decreased compared with wild type, which supports previous assumptions that endogenous substrates serve as source of electrons for hydrogen formation. These results demonstrate the importance of Nda2 for nonphotochemical PQ reduction and associated processes in C. reinhardtii. [less ▲]

Clownfishes (i.e. Amphiprion akallopisos) are territorial fishes that use sound production to defend their anemone territory. They live in social groups which display a size-based dominance hierarchy. In such a system, agonistic interactions are frequent and play an important role in the social organization. In addition, these interactions are often associated with sounds. In this study, we compared the sonic features between individuals of different sizes and in different sexual status (juvenile, male and female). The existent relationship between fish size and swimbladder size also implied to seek the swimbladder role in the sound production. Sound analyses showed that juveniles, males and females had distinct sounds in the dominant frequency and pulse duration. These differences were however not in relation to the sexual state; influence of sex on sonic features being mainly the result of a size dimorphism between sexes. Differences in calls were therefore due to the respective size of the emitter. This observation highlighted the role of the swimbladder as a resonance chamber. This role was also reinforced because the experimental filling of the swimbladder with physiological liquid significantly modified the acoustic features. In A. akallopisos, frequency and pulse duration are directly related to swimbladder size, and thus to fish size. This relationship provides strong evidence that the emitter could be identified by its calls. [less ▲]

L’ouvrage a pour objet central l’analyse des intégrations régionales dans la politique mondiale post-bipolaire. Une importante partie des travaux consacrés à l'explication du régionalisme partent d'une approche essentiellement endogène accordant une attention distraite aux déterminants exogènes. Pour comprendre la nature du nouveau régionalisme, il faut le situer dans une perspective globale qui tient compte de l’interrelation entre les niveaux national, régional et global. Bien que le régionalisme renvoie à des logiques internes propres, le phénomène est fortement conditionné et façonné par l’extérieur du fait qu’il évolue en interaction directe et constante avec le monde économique et politique international, et qu’il fait l’objet de politiques menées par des acteurs dominants de l’arène mondiale. Les déterminants extérieurs sont donc essentiels pour comprendre l’évolution du régionalisme. Pour étayer cette hypothèse, l’ouvrage se concentre sur l’étude du régionalisme latino-américain et plus précisément sur le Marché commun du Sud (MERCOSUR) qui fait l’objet de stratégie différente de la part de l’Union européenne et des Etats-Unis.
