Todo o conhecimento do munda na literatura: as disciplinas do currículo nacional dos anos iniciais do ensino fundamental em Cacoete, de Eva Furnari. -

Nous comprenons que la littérature, quelle que soit l'adjectif qui accompagne - enfant, adolescent ou adulte - est l'art. L'art de la parole qui crée des mondes possibles, pas réel, à travers un langage très élaboré et complexe qui permet la compréhension de toute la l'expérience humaine. D'autre part, la réalité de l'éducation brésilienne nous montre que nos étudiants ont de la difficulté à comprendre des textes écrits, ce que compromettre l'apprentissage de toutes les matières du programme. Dans ce sens, cette étude a eu l'óbjective à à souligner les possibilités que nous avons d'incorporer la literature brésilienne pour les enfants e les jeunes - appropriée aux étudiants de l'enseignement de base, les enfants et les jeunes - comme um élément transdisciplinaire, associant toutes les disciplines du programme scolaire de l'école élémentaire, notre découpure. Ainsi, nous le signalons dans Cacoete, d' Eva Furnari (2005), des éléments de toutes les matières du programme d'études de cette étape scolaire Brésilienne, afin de montrer aux les enseignants de tous les domaines qui le travail avec la littérature conduit nécessairement à la compréhension de toutes la connaissance. Notre étude a été réalisée sous une approche qualitative de caractère bibliographique. Pour l'embasement théorique nous utilisons de auteurs qui recherche le concept et les spécificités du texte littéraire, selon Rolland Barthes (2007) et Tzvetan Todorov (2009) aussi que des auteurs qui l'étudient spécifiquement de la littérature pour les enfants, selon Nelly Novaes Coelho (2006) et Fanny Abramovich (1983; 1999). Ils ont été également consultées des auteurs qui recherche sur la lecture, la littérature et l'école, selon John Wanderley Geraldi (2006), Marisa Lajolo (1997), Ana Maria Machado (2011), Iara Conceição Bitencourt Neves et al (2003), Roxane Rojo (2002), Ezequiel Theodoro da Silva (1988)...

Protease-inhibiting, molecular modeling and antimicrobial activities of extracts and constituents from Helichrysum foetidum and Helichrysum mechowianum (compositae)

Background Helichrysum species are used extensively for stress-related ailments and as dressings for wounds normally encountered in circumcision rites, bruises, cuts and sores. It has been reported that Helichysum species are used to relief abdominal pain, heart burn, cough, cold, wounds, female sterility, menstrual pain. Results From the extracts of Helichrysum foetidum (L.) Moench, six known compounds were isolated and identified. They were 7, 4′-dihydroxy-5-methoxy-flavanone (1), 6′-methoxy-2′,4, 4′-trihydroxychalcone (2), 6′-methoxy-2′,4-dihydroxychalcone -4′-O-β-D-glucoside (3), apigenin (4), apigenin-7-O-β-D-glucoside (5), kaur-16-en-18-oic acid (6) while two known compounds 3,5,7-trihydroxy-8-methoxyflavone (12), 4,5-dicaffeoyl quinic acid (13) together with a mixture of phytosterol were isolated from the methanol extract of Helichrysum mechowianum Klatt. All the compounds were characterized by spectroscopic and mass spectrometric methods, and by comparison with literature data. Both extracts and all the isolates were screened for the protease inhibition, antibacterial and antifungal activities. In addition, the phytochemical profiles of both species were investigated by ESI-MS experiments. Conclusions These results showed that the protease inhibition assay of H. foetidum could be mainly attributed to the constituents of flavonoids glycosides (3, 5) while the compound (13) from H. mechowianum contributes to the stomach protecting effects. In addition, among the antibacterial and antifungal activities of all the isolates, compound (6) was found to possess a potent inhibitor effect against the tested microorganisms. The heterogeneity of the genus is also reflected in its phytochemical diversity. The differential bioactivities and determined constituents support the traditional use of the species. Molecular modelling was carried out by computing selected descriptors related to drug absorption, distribution, metabolism, excretion and toxicity (ADMET).

Load models support sustainable: planning for Brazil s reservoir aquaculture

Cage aquaculture in hydroelectric reservoirs has great potential for expansion in Brazil, but there are concerns of negative environmental impacts. The environmental sustainability of cage culture depends on hamornization between farming practices and the hydrological peculiarities of the site. Mass balance modeling can estimate the amounts of nutrients that can be loaded without triggering eutrophication and resulting maximum allowable production volume. Careful climate zoning can also assist proper siting.
