Filme O Jardim Secreto: uma experiência com a leitura das legendas cinematográficas

By analyzing the pedagogical practices in respect of acts of reading in the current context of school education institutions vital, it is clear that they are linked to decipher. But it is believed that for the student to learn to read is necessary dialogue with the text, attribute meaning to writing and comprehension. When thinking about the use of technologies such as film subtitles, it is believed that they allow readers to form since they require a quick read without using the decryption with the attribution of meaning to follow the entire course of the film. This paper aims to present and analyze a film session the project subtitled and dubbed films in public schools and training of the reader, which investigates the contributions of cinematic legends in training readers in elementary school. In this paper we present data on the session of the film The Secret Garden, with students between six and ten years old in a public school in Marilia, SP. The session took place in film school, in a room adapted. When analyzing the results, we observed that reading subtitles contributes to children are not attached to decipher, because we used reading strategies to understand the plot and tried to dialogue with the text. This approach not only contributes reader for reading the screens, but also in fixed supports, for developing specific tactics for the scrolling text which can be applied to the texts on the immobilized support.

Platinum-Group Minerals in Chromitites of the Niquelandia Layered Intrusion (Central Goias, Brazil): Their Magmatic Origin and Low-Temperature Reworking during Serpentinization and Lateritic Weathering

A variety of platinum-group-minerals (PGM) have been found to occur associated with the chromitite and dunite layers in the Niquelandia igneous complex. Two genetically distinct populations of PGM have been identified corresponding to phases crystallized at high temperatures (primary), and others formed or modified during post-magmatic serpentinization and lateritic weathering (secondary). Primary PGM have been found in moderately serpentinized chromitite and dunite, usually included in fresh chromite grains or partially oxidized interstitial sulfides. Due to topographically controlled lateritic weathering, the silicate rocks are totally transformed to a smectite-kaolinite-garnierite-amorphous silica assemblage, while the chromite is changed into a massive aggregate of a spinel phase having low-Mg and a low Fe3+/Fe2+ ratio, intimately associated with Ti-minerals, amorphous Fe-hydroxides, goethite, hematite and magnetite. The PGM in part survive alteration, and in part are corroded as a result of deep chemical weathering. Laurite is altered to Ru-oxides or re-crystallizes together with secondary Mg-ilmenite. Other PGM, especially the Pt-Fe alloys, re-precipitate within the altered chromite together with kaolinite and Fe-hydroxides. Textural evidence suggests that re-deposition of secondary PGM took place during chromite alteration, controlled by variation of the redox conditions on a microscopic scale.

Morfologia e expressão dos MRF’s no músculo esquelético de ratos submetidos a estímulo atrófico e recuperação por treinamento físico

Recent research advances in understanding the cellular and molecular mechanisms that underlie the processes of hypertrophy and atrophy. This may contribute to development of effective therapeutic strategies to attenuate or block the loss of muscle tissue associated with aging and pathological conditions. In this context, myogenic factors that control the activity of satellite cells have been studied to better understand the events involved in the recovery of muscle mass. Among them, we highlight the Myogenic Regulatory Factors (MRFs), which have been described as potential mediators of muscle growth. The objectives of this study evaluated the morphofunctional adaptations and gene expression of MRFs (MyoD and myogenin) in skeletal muscle (soleus) subjected to an atrophic stimulus followed by physical training. It was used 64 male Wistar rats (80 days, 250 to 300 g), divided into 8 groups (n = 8): C: control animals a week, I: Animals immobilized a week, C3: control animals 3 days; R3: Animals immobilized and recovered for 3 days, T3: Animals immobilized and submitted to exercise for 3 days; C7: Animals controls 7 days; R7: Animals immobilized and subsequently recovered by 7 days, T7: Animals immobilized and subsequently subjected to exercise for 7 days. Initially, the animals in groups I, R3, R7, T3 and T7, were submitted to 7 days of immobilization of the hind limb. Muscle atrophy was confirmed after a direct statistical comparison of the values of cross-sectional area (CSA) of muscle fibers studied in animals in groups I and C, sacrificed immediately after the immobilization period. Then, the groups T3 and T7 were submitted a rehabilitation program with muscle aerobic exercise (swimming) for 3 and 7 days respectively. The groups C, C3 and C7 were kept without stimulus atrophic and were not subjected to exercise. At the end of the experiment, the animals were sacrified and the soleus muscle removed. The quantitative analysis of gene expression ...

Determinação de Cd, Cu, Ni, Pb e Zn em águas marinhas oriundas da Bacia Potiguar utilizando a técnica de difusão em filmes finos por gradiente de concentração (DGT)

The DGT technique has been used to determine and better understand the dynamics and bioavailability of metals in the sea near to marine outfalls. In this work, the DGT was assessed for the determination of Cd, Pb, Cu, Zn and Ni in marine water samples from Potiguar Basin in its conventional aspect (binding agent, Chelex-100 and diffusive agent: Diffusive polyacrylamide gel (D) and restrictive (R)) and determination of Pb and Cd through its alternative aspect (binding agent: Saccharomyces cerevisiae immobilized in agarose gels and diffusive agent: 3MM Chromatography Paper). The deployment curves for long periods of immersion in the sample, showed a good linear correlation for the conventional aspect to Zn (D: R²=0.9586, R: R²=0.9444), Ni (D: R²=0.9789, R: R²=0.9286) and Cu (D: R²=0.764, R: R²=0.8143), and alternative to Pb (R²=0.9228) and Cd (R²=0.9673). The results of the organic and inorganic composition analysis in conventional aspect, showed that for every element there is no significant fraction of organic compounds in the sample. In addition, considering the alternative aspect, the comparison of obtained and expected masses suggests that some of the Pb is not labile and that the main retention mechanism of Pb for S. Cerevisiae occurs through ion exchange
