Martian basalts can be classified in at least two geochemically different families: enriched and depleted shergottites. Enriched shergottites are characterized by higher incompatible element concentrations and initial 87Sr/86Sr and lower initial 143Nd/144Nd and 176Hf/177Hf than depleted shergottites. It is now generally admitted that shergottites result from the melting of at least two distinct mantle reservoirs. Some of the olivine-phyric shergottites (either depleted or enriched), the most magnesian Martian basalts, could represent primitive melts, which are of considerable interest to constrain mantle sources. Two depleted olivine-phyric shergottites, Yamato 980459 and Nothwest Africa (NWA) 5789, are in equilibrium with their most magnesian olivine and their bulk rock compositions are inferred to represent primitive melts. Larkman Nunatak 06319 and NWA 1068, the most magnesian enriched basalts, have bulk Mg# that are too high to be in equilibrium with their olivine megacryst cores. Parental melt compositions have been estimated by subtracting the most magnesian olivine from the bulk rock composition, assuming that olivine megacrysts have partially accumulated. However, because this technique does not account for the actual petrography of these meteorites, we used image analysis to study these rocks history, reconstruct their parent magma and understand the nature of oli-vine megacrysts. Our image analysis results are supported by a series of high-pressure experiments performed on LAR 06319 bulk rock composition to test if it could represent a primitive melt, and understand its crystallization history.

This paper aims to raise some difficulties inherent in the status of Saussure’s “work”. Having published little, but written much, Saussure has left us (together with his theories) a philological problem which is far from being resolved – most of his manuscripts (90% approximately) remaining unpublished, and most of his ideas have remained unfinished. We intend to highlight the need to take explicitly, in editing and transmitting Saussurean “ideas” and “work”, a coherent set of philological principles, fit for showing the state of the this particular “text” without distortion.

La série de rapports militaires encore présents dans la correspondance de la légation britannique à Bruxelles est incomplète et moins riche que les nombreux rapports conservés aux archives de l’Armée de Terre à Vincennes ; il n’empêche, le nombre de documents existants demeure important et susceptible de livrer des informations de première main sur les relations militaires belgo-britanniques avant la Première Guerre mondiale. Notre intervention consistera à faire un état des lieux des documents conservés, de leur localisation et de ce qu’ils peuvent nous apprendre sur la perception britannique du territoire belge. A l’aide des recherches que nous avons réalisées dans le cadre de notre thèse sur les plans français et allemands dans leurs rapports avec la Belgique, nous élargirons nos réflexions sur les relations belgo-britanniques dans une perspective militaire européenne.

In models with flavor symmetries in the leptonic sector leptogenesis can take place in a very different way compared to the standard leptogenesis scenario. We study the generation of a B−L asymmetry in these kind of models in the flavor symmetric phase pointing out that successful leptogenesis requires (i) the right-handed neutrinos to lie in different irreducible representations of the flavor group; (ii) the flavons to be lighter at least that one of the right-handed neutrino representations. When these conditions are satisfied leptogenesis proceeds due to new contributions to the CP violating asymmetry and — depending on the specific model — in several stages. We demonstrate the validity of these arguments by studying in detail the generation of the B − L asymmetry in a scenario of a concrete A 4 flavor model realization. [less ▲]

Six types of fats (oils, shortenings and margarines) from different vegetable (hydrogenated or not) or animal origins have been studied in a cake model. Cakes have been characterized through Texture Profile Analysis and sensory evaluation. Texture analysis shows that studied fats can be classified in two main categories, giving different texture characteristics: liquid oils on one hand and fats containing a solid fraction on the other. Descriptive sensory evaluation leads to the same conclusions. On the contrary, hedonic sensory evaluation shows no difference between the different fats. The results in this paper indicate also that shortenings classical solid fat content can be reduced, without impact on the final product characteristics. This paper shows thus that the nutritional profile of bakery products can be improved, without sacrificing the sensory quality. Notably, the palm oil content (and thus the saturated fatty acids content) reduction of today shortenings could be an answer to nutritional and environmental concerns. [less ▲]
