This article analyzes the data resultant of the accomplishment, between 2008 and 2009, of an extension and research project on the international exchange of letters between teachers and students from elementary schools in the towns of Garça and Marília, São Paulo State, Brazil, with a school in the city of Azaruja, Portugal and another in the city of Luanda, Angola. It was developed by a team of students and teachers, UNESP, Marília, in order to promote the exchange via personal letters for that students, between 8 and 9 years old, could take possession of the written language, in this case Portuguese, and understand it as an instrument steeped in culture. The choice of this kind in the world of the epistolary genre was made because it promotes the participation of the Other in the configuration of dialogic relations in the elaboration of the statements, taken as a reference in a Bakhtinian conception of language. It aimed to (1) point, in the letters exchanged between teachers and students between the Portuguese, Brazilians and Angolans in the early years, the evidence of authorship linguistic behavior that could signal the beginning of autonomy in the use of the written modality of language, or signs of submissive behavior; (2) reveal the cultural content of language tools used to construct indicators listed on the customs of each people, including those constituting school doings. For the generation of data were used principles of action research, which enabled direct action, along with Brazilian teachers, and indirectly, in the case of the foreign teachers. From the analysis of the corpus of research - letters exchanged between teachers and students - it is clear that the appropriation of language as a speech act realized in human relations makes the old personal correspondence a powerful instrument of development in the area of the written language.

The growth and the metabolism of Bifidobacterium adolescentis MB 239 fermenting GOS, lactose, galactose, and glucose were investigated. An unstructerd unsegregated model for growth of B. adolescentis MB 239 in batch cultures was developed and kinetic parameters were calculated with a Matlab algorithm. Galactose was the best carbon source; lactose and GOS led to lower growth rate and cellular yield, but glucose was the poorest carbon source. Lactate, acetate and ethanol yields allowed calculation of the carbon fluxes toward fermentation products. Similar distribution between 3- and 2-carbon products was observed on all the carbohydrates (45 and 55%, respectively), but ethanol production was higher on glucose than on GOS, lactose and galactose, in decreasing order. Based on the stoichiometry of the fructose 6-phosphate shunt and on the carbon distribution among the products, ATP yield was calculated on the different carbohydrates. ATP yield was the highest on galactose, while it was 5, 8, and 25% lower on lactose, GOS, and glucose, respectively. Therefore, a correspondance among ethanol production, low ATP yields, and low biomass production was established demonstrating that carbohydrate preferences may result from different sorting of carbon fluxes through the fermentative pathway. During GOS fermentation, stringent selectivity based on the degree of polymerization was exhibited, since lactose and the trisaccharide were first to be consumed, and a delay was observed until longer oligosaccharides were utilized. Throughout the growth on both lactose and GOS, galactose accumulated in the cultural broth, suggesting that β-(1-4) galactosides can be hydrolysed before they are taken up. The physiology of Bifidobacterium adolescentis MB 239 toward xylooligosaccharides (XOS) was also studied and our attention was focused on an extracellular glycosyl-hydrolase (β-Xylosidase) expressed by a culture of B. adolescentis grown on XOS as sole carbon source. The extracellular enzyme was purified from the the supernatant, which was dialyzed and concentrated by ultrafiltration. A two steps purification protocol was developed: the sample was loaded on a Mono-Q anion exchange chromatography and then, the active fractions were pooled and β-Xylosidase was purified by gel filtration chromatography on a Superdex-75. The enzyme was characterized in many aspects. β- Xylosidase was an homo-tetramer of 160 kDa as native molecular mass; it was a termostable enzyme with an optimum of temperature at 53 °C and an optimum of pH of 6.0. The kinetics parameter were calculated: km = 4.36 mM, Vmax = 0.93 mM/min. The substrate specificity with different di-, oligo- and polysaccharides was tested. The reactions were carried out overnight at pH 7 and at the optimum of temperature and the carbohydrates hydrolysis were analyzed by thin layer chromatography (TLC). Only glycosyl-hydrolase activities on XOS and on xylan were detected, whereas sucrose, lactose, cellobiose, maltose and raffinose were not hydrolyzed. It’s clearly shown that β-Xylosidase activity was higher than the Xylanase one. These studies on the carbohydrate preference of a strain of Bifidobacterium underlined the importance of the affinity between probiotics and prebiotics. On the basis of this concept, together with Barilla G&R f.lli SpA, we studied the possibility to develop a functional food containing a synbiotic. Three probiotic strains Lactobacillus plantarum BAR 10, Streptococcus thermophilus BAR 20, and Bifidobacterium lactis BAR 30 were studied to assess their suitability for utilization in synbiotic products on the basis of antioxidative activity, glutathione production, acid and bile tolerance, carbohydrates fermentation and viability in food matrices. Bile and human gastric juice resistance was tested in vitro to estimate the transit tolerance in the upper gastrointestinal tract. B. lactis and L. plantarum were more acid tolerant than S. thermophilus. All the strains resisted to bile. The growth kinetics on 13 prebiotic carbohydrates were determined. Galactooligosaccharides and fructo-oligosaccharides were successfully utilized by all the strains and could be considered the most appropriate prebiotics to be used in effective synbiotic formulations. The vitality of the three strains inoculated in different food matrices and maintained at room temperature was studied. The best survival of Lactobacillus plantarum BAR 10, Streptococcus thermophilus BAR 20, and Bifidobacterium lactis BAR 30 was found in food chocolate matrices. Then an in vivo clinical trial was carried out for 20 healthy volunteers. The increase in faecal bifidobacteria and lactobacilli populations and the efficacy of the pre-prototype was promising for the future develop of potential commercial products.

Quelle est la différence entre un flibustier et un pirate ? Ce projet de recherche est basé sur cette question enfantine. En fait, les historiens contemporains, qui ont consacré de nombreuses pages à la « piraterie » et à la « flibuste » de l’âge moderne, n’ont pas réussi à répondre à cette – apparemment – simple question. Les reconstructions et les théories développées, en fait, ont assimilé ces deux phénomènes, en traitant les deux termes comme de simples synonymes. Mais, si cela peut être considéré comme vrai aujourd’hui, il n'était pas au cours des XVIIème et XVIIIème siècles. À l'époque, pirate était équivalent de « hostis humani generis », et comme tel craint et persécuté. Les flibustiers, au contraire, ont été considérés comme l’un des groupes les plus importants dans les premiers établissements des îles de la Mer des Caraïbes. En outre, le terme flibustier, dans la correspondance des gouverneurs français, se réfère à un élément considéré comme essentiel pour la réussite du processus de construction de la colonie, et également cruciale pour la consolidation des établissements américains. C’est donc la relation spéciale entre les flibustiers et le Nouveau Monde est l’objet de cette thèse. En utilisant une approche historico-culturel, on a essayé de contextualiser le phénomène de la flibuste dans le « processus d’américanisation » des premières communautés européennes en Amérique. La relation étroite entre les colons des établissements français de Saint-Domingue (aujourd’hui Haïti) et les nombreux espaces - économique, militaire, diplomatique, social, humain - des Caraïbes a fait des flibustiers un élément fortement « américanisé ». Grâce à la lecture des documents d'archives et les mémoires des années entre 1684 et 1727, on a reconstruit la dynamique de la relation entre ce groupe et le contexte américain, avec une attention particulière à la dynamique culturelle et sociale.

Si les hommes bénéficient d’emblée de mythes (Pygmalion, Orphée) qui légitiment et motivent leur créativité, il faut attendre Corinne (1807) de Mme Staël et Consuelo (1842) de George Sand pour que le mythe de la femme créatrice trouve enfin, dans la littérature européenne, à se concrétiser et à se développer sous la forme de Künstlerromane féminins. Corinne la poétesse et Consuelo la cantatrice sont devenues des exemples littéraires non seulement pour les femmes victoriennes, comme le montre par exemple le livre de Linda Lewis intitulé Germaine de Staël, George Sand and the Victorian Woman Artist, mais également pour les femmes polonaises issues des classes favorisées - qui lisaient d’ailleurs couramment en français. En effet, même si elles ont été officiellement décriées par la critique conservatrice polonaise pour leur « immoralité », George Sand et Mme de Staël ont été lues, bien lues et même beaucoup lues par leurs contemporaines polonaises - comme le témoigne la correspondance de ces dernières, dans laquelle elles ont moins de peine à se livrer. Le thème de la femme artiste déchirée entre la carrière publique et la vie privée, tel qu’il est représenté dans Corinne et dans Consuelo, a en particulier attiré toute leur attention et suscité chez les femmes écrivains le désir d’apporter de nouvelles manières de résoudre ce conflit. Dans cet article, le Künstlerinroman polonais Książka Pamiątek (Livre des souvenirs, 1846) de Narcyza Żmichowska fait l’objet d’une analyse comparative détaillée avec les deux Künstlerinromane français dont par ailleurs il se réclame.
