Relatório da prática de ensino supervisionada na Escola Básica 2, 3/S Cunha Rivara, Arraiolos

O presente relatório tem como objetivo a explanação e a discussão de forma concisa da atividade docente desenvolvida no ano letivo 2012/2013, na Escola Básica 2,3/S Cunha Rivara de Arraiolos com as turmas do 8.º C e 11.º D nas disciplinas de Ciências Naturais e Saúde respetivamente, sob a orientação da Doutora Marília Cid. Apresentam-se os fundamentos teóricos que sustentaram o delineamento de todas as metodologias e estratégias de ensino no sentido de promover situações de aprendizagem significativa aos alunos das turmas referidas. Este é também um testemunho da participação ativa no projeto de educação para a saúde em colaboração com as entidades promotoras de saúde no Concelho de Arraiolos no sentido de organizar atividades extracurriculares propiciadoras da aprendizagem nesta dimensão, com a dinamização de sessões de esclarecimento de Educação Sexual a várias turmas da escola e a produção de um website informativo e de apoio aos alunos do 3.º Ciclo do Ensino Básico e do Ensino Secundário sobre Educação Sexual. Foi apanágio deste trabalho a análise e reflexão também evidenciadas no trabalho de investigação sobre as atividades desenvolvidas no âmbito da Educação para a Saúde mas também em toda a atividade de lecionação. Esta análise e reflexão, bem como a pesquisa individual e o trabalho colaborativo permitiram o desenvolvimento progressivo das minhas capacidades, da qualidade do trabalho desenvolvido e o melhoramento da formação académica. /ABSTRACT: This report aims at explaining concisely and discussion of teaching developed in the academic year 2012/2013, at Escola Básica 2,3 / S Cunha Rivara in Arraiolos with classes C from 8th grade class and D from 11th , in the disciplines of Natural Sciences and Health respectively under the guidance of PhD Teacher Marilia Cid. Here we present the theoretical foundations that supported the design of all methodologies and teaching strategies to promote meaningful learning situations for students of classes above. This is also a testament to the active participation in the design of health education in collaboration with the health promoters in the County of Arraiolos to organize extracurricular activities conducive learning these dimensions, the organization of information sessions to various Sex Education school classes and the production of an informational website to support the students of the 3rd cycle and Secondary Education on Sexual Education. It was the hallmark of this work, analysis and reflection evidenced in research work on the activities within the Health Education but also of the entire teaching activity. This analysis and reflection as well as individual research and collaborative work allowed the progressive development of my abilities, quality of work and the improvement of academic training.

Determinação da toxicidade aguda e caracterização de risco ambiental do herbicida Roundup (glifosato) sobre três espécies de peixes

Considering their commercial importance, as these are the species of freshwater fish more commercialized in Brazil, their occurence in different kinds of aquatic environments (lakes, rivers and dams) and for being tolerant to a wide range of variation of various physical parameters and chemical water, the fish species Oreochromis niloticus, Cyprinus carpio and Colossoma macropomum were chosen for this study, furthermore, to test the toxicity we used the herbicide Roundup. The fingerlings of tilapia (Oreochromis niloticus), commun carp (Cyprinus carpio) and tambaqui (Colossoma macropomum) were submitted to the herbicide roundup in the following concentrations: 0.0 (control); 18,06; 19,10; 20,14; 21,18 and 22,22 mg.L-1, 0.0 (control); 13,89; 14,86; 15,83; 16,81 and 17,78 mg.L-1, and 0.0 (control); 18,06; 19,10; 20,14; 21,18 and 22,22 mg.L-1, respectively, three for 96 hours. The LC50 - 96h for O. niloticus, C. carpio and C. macropomum was 21,63, 15,33 and 20,06 mg.L-1 of the herbicide roundup, respectively. The results show that this herbicide is classified as slightly toxic to the three species. The values of dissolved oxygen, pH and temperature recorded in the aquarium control and aquarium experimental of the three fish species have remained without significant variations during the tests, which reduces the possibility of death caused by sudden variations of these parameters during the 96 hours the experiment. The values of LC50 between different species of fish were observed, noting that the species O.niloticus, C. carpio and C. macropomum showed no expressive differences. The values of environmental risk of Roundup were calculated to obtain more stringent parameters in assessing the dangerousness of those on nontargets. The risk of environmental contamination by Roundup for the Nile tilapia, common carp, and tambaqui are low for the lowest application rate (1 L.ha-1) and depths (1.5 and 2.0 m). The dilution of 100%, the highest recommended dose (5 L.ha-1) and depths (1.5 and 2.0 m) the risk is moderate for the three species. The values of the Risk Ratio (QR) were greater than 0,1, indicating that the values of the CAE and LC50 are above acceptable levels and there is a need, this study, a refinement in ecotoxicological tests

Homogalactanas sulfatadas da alga Codium isthmocladum com atividade anticoagulante

Since the first description of sulfated polysaccharides from seaweeds, the biological activities of these compounds have been evaluated under different aspects and experimental procedures. Among the broad biological activities presented by seaweed polysaccharides, anticoagulant action appears as a promising function. In this present study we have obtained sulfated polysaccharides from the green seaweed Codium isthmocladium by proteolytic digestion, followed by separation into five fractions (0.3, 0.5, 0.7, 0.9 and 1.2) by sequential acetone precipitation. The chemical analyses have demonstrated that all fractions are composed mainly by sulfated polysaccharides. The anticoagulant activity of these fractions was determined by activated partial thromboplastin time (aPTT) and prothrombin time test (PT) using citrate normal human plasma. None fraction has shown anticoagulant activity by PT test. Furthermore, all of them have shown anticoagulant activity by aPTT test. These results indicated that the molecular targets of these sulfated polysaccharides are mainly in the intrinsic via of the coagulation cascade. Agarose gel electrophoresis in 1,3-diaminopropane acetate buffer, pH 9.0, stained with 0.1% toluidine blue showed the presence of two or three bands in several fractions while the fraction 0.9 showed a single spot. By anion exchange chromatography, the acid polysaccharides from the 0.9 acetone fraction were separated into two new fractions eluted respectively with 2.0 and 3.0 M NaCl. These compounds showed a molecular weight of 6.4 and 7.4 kDa respectively. Chemical analyses and infrared spectroscopy showed that Gal 1 and Gal 2 are sulfated homogalactans and differ one from the other in degree and localization of sulfate groups. aPPT test demonstrated that fractions 2,0 and 3,0M (Gal1 and Gal 2, respectively) have anticoagulant activity. This is the first time that anticoagulant sulfated homogalatans have been isolated from green algae. To prolong the coagulation time to double the baseline value in the aPTT, the required amount of sulfated galactan 1 (6,3mg) was similar to low molecular heparin Clexane®, whereas only 0,7mg of sulfated galactan 2 was needed to obtain the same effect. Sulfated galactan 2 in high doses (250mg) induces platelet aggregation. These results suggest that these galactans from C. isthmocladum have a potential application as an anticoagulant drug

Metafísicas caníbales. Líneas de Antropología Posestructural. Eduardo Viveiros de Castro. Katz Editores. Madrid. 2010. En: Avá, nº 20

¿Puede leerse la obra de un estructuralista como Claude LéviStrauss a partir del posestructuralismo de Gilles Deleuze? ¿Cuánto le debe el primero, y su formulación del estructuralismo, al pensamiento amerindio? No sólo en datos, sino en la propia formulación teórica. Estas son algunas de las preguntas capitales que se hace Eduardo Viveiros de Castro en el primero de sus libros traducidos al español, denominado Metafísicas Caníbales, un libro que reelabora y desarrolla artículos anteriormente publicados por el autor. Etnólogo y amazonista brasileño, su influencia teórica se ha acentuado al proponer el concepto de perspectivismo amazónico.
