Este artigo focaliza discursos referentes à formação de duas gerações brasileiras de professores dos anos iniciais do Ensino Fundamental. Com relação ao primeiro momento, entre o final da década de 1980 e início da década de 1990, procedeu-se o estudo de documentos relativos à proposta curricular do Projeto CEFAM/SP, o que revelou discursos que enfatizavam uma formação docente voltada para o trabalho coletivo e a atitude crítico-reflexiva. Já no segundo período, correspondente à geração de professores formada a partir da segunda metade da década de 1990, as propostas de formação docente (representadas por diretrizes, referenciais e decretos federais) são marcadas pela influência de organismos internacionais e por um viés econômico, seguindo uma direção pragmatista baseada em competências individuais, o que aponta para um enfraquecimento político do magistério, enquanto grupo profissional. Questiona-se, assim, a pertinência de se considerar o momento atual como sendo de profissionalização docente.

The present invention relates to a mutant of Salmonella gallinarum that is defective in the CobS and CbiA (SGCobSCbiA) genes, which are associated with the production of cobalamin by the bacterium in anaerobic conditions, for use as vaccines. The present invention also relates to the use of said mutant Salmonella gallinarum strain for inducing protection in birds against infection by the homologous natural strain and Salmonella enteritidis strain by means of a vaccine.

The present invention comprises composites with multifunctional characteristics, being capable of substituting glass, with significant advantages, with particular emphasis on flexibility, for a variety of applications such as, for example, display screens and others. Among other aspects, the product that constitutes the object of the invention is particularly characterized by rendering bacterial cellulose transparent, in addition to being flexible, biocompatible and able to replace glass in 100% of possible applications. Among other aspects, the development of the composites according to the present invention allows an effective increase in optical transmission, enabling an optical transmission of more than 90%, such transparency being necessary, equally, for the development of medical devices, for example.

The present invention discloses the use of the bacterial cellulose membrane in ligament, tendon and synovial capsule reconstructions according to the methods described in the technical description of the invention. Said material could be used in the reconstruction of ligaments and tendons (the knee cruciate ligaments, patellar ligament, Achilles tendon, quadriceps tendon, etc.) and the synovial capsule.

The present invention describes a method for transforming chemolithotrophic acidophilic bacteria using electroporation technology. The proposed method allows transforming a bacterial line using a transformation vector, the pAF vector, which contains an origin of vegetative replication that allows the vector to replicate inside the bacteria without altering the natural physiological functions of the latter. Also disclosed is the use of the bacteria modified according to the invention in bioleaching processes of sulphated copper, gold, uranium, nickel, zinc and cobalt ore, inter alia.

This investigation addresses the possibility of teaching themes related to environmental issues in Physical Education. We identified and classified such issues as: administrative and economic, aesthetic and philosophical, virtual, historical and geographical, sociological and political, physical and natural. Then, we discussed how the specific dynamics of culture, movement, and environment raises certain questions about each theme's relevance and its repercussions on teachers' professionalism. We believe that in the context of the daily intervention there are perspectives for both adaptation and transformation that might be further developed during classes in collaboration with the students.

Several countries have been passed by change processes in their fundamental geodesic structure with the focus on the adoption of geocentric reference systems. In Brazil, the adoption of the SIRGAS2000 evolves the coexistence of two realizations from the COrrego Alegre system, two realizations from the SAD69 system and one realization from the SIRGAS2000 system. To make use of products in the old reference systems, methods of coordinate transformation between the existent reference frames are necessary. So, in this paper one solution for the transformation between coordinates from different reference frames, based on Thin-Plate Splines (TPS), that allows the estimation of parameters from one linear transformation and also one non-linear model is presented. The TPS model was developed to work with tridimensional coordinates and in this paper the results and analysis are performed with simulated data and also with data from the official Brazilian Geodetic System (SGB). In the check points from SAD69 stations (realization of 1996 - SAD69/96), the values of RMSE obtained were of 78,2 mm in latitude and 67,5 mm in longitude, before the transformation to the SIRGAS2000. In the comparison between the TPS model and ProGriD (Brazilian software provided by IBGE), the statistical indicators were reduced in 97%, by using the TPS model. Based in the obtained results from real dataset, the TPS model appears to be promising, since it allows improving the quality of transformation process with simultaneous distortion modeling.
