Coastal wetlands are characterized by high biodiversity, which is one of the main criteria considered when establishing protection policies or when proposing adequate management actions. In this study, the crustacean and aquatic insect composition of the Empord`a wetlands is described. These two faunal groups contribute highly to the total biodiversity in these wetlands but are seldom considered when managing natural areas. A selection (84 sampling points) of all water body types present in the Empord`a wetlands were sampled monthly (surber and dip net with a 250 μm mesh). Sampling was carried out during 3 surveys (1991-92, 1996-97 and 1999-2000). A rich fauna of 125 crustacean and 295 aquatic insect taxa was identified. We characterized each water body type using the most abundant species and the relative species richness of the taxonomic groups. A classification of the water body types, according to similarity between inventories, groups the brackish and hyperhaline systems in one cluster and the various freshwater systems in another one. Among freshwater systems, lotic waters and freshwater wetlands have a high similarity, whereas rice fields and freshwater springs have a low similarity

We introduce a method for surface reconstruction from point sets that is able to cope with noise and outliers. First, a splat-based representation is computed from the point set. A robust local 3D RANSAC-based procedure is used to filter the point set for outliers, then a local jet surface - a low-degree surface approximation - is fitted to the inliers. Second, we extract the reconstructed surface in the form of a surface triangle mesh through Delaunay refinement. The Delaunay refinement meshing approach requires computing intersections between line segment queries and the surface to be meshed. In the present case, intersection queries are solved from the set of splats through a 1D RANSAC procedure

Green coconut shells were treated with acid, base and hydrogen peroxide solutions for 3, 6, 12 and 24 h for removing toxic metals from synthetic wastewater. The removal of ions by the adsorbent treated with 0.1 mol L-1 NaOH/ 3h was 99.5% for Pb2+ and 97.9% for Cu2+. The removal of Cd2+, Ni2+, Zn2+, using adsorbent treated with 1.0 mol L-1 NaOH/3 h, was 98.5, 90.3 and 95.4%, respectively. Particle size, adsorbent concentration and adsorption kinetics were also studied. An adsorbent size of 60-99 mesh and a concentration of 30-40 g/L for 5 min exposure were satisfactory for maximum uptake of Pb2+, Ni2+, Cd2+, Zn2+ and Cu2+ and can be considered as promising parameters for treatment the aqueous effluents contaminated with toxic metals.

Ozonation tests with and without prior filtration by means of a 50 micron mesh cartridge filter were conducted with primary sanitary effluents. Filtration led to increased inactivation efficiencies with regard to total and thermotolerant coliforms but it did not seem to influence heterotrophic plate count (HPC) bacteria inactivation efficiencies significantly. Application of the Chick-Watson model to experimental data obtained in the situation of constant inactivation showed that the ozone dosage was more important to bacterial inactivation than the contact time with regard to the cases of thermotolerant coliform inactivation in filtered samples and HPC bacteria and total coliform inactivation in non-filtered samples.

The metal ions removal on cashew bagasse, a low-cost material, has been studied by batch adsorption. The parameters chemical treatment, particle size, biosorbent concentration, and initial pH were studied. In this study the maximum ions removal was obtained on the cashew bagasse treated with 0.1 mol/L NaOH/3 h, at optimum particle size (20-59 mesh), biosorbent concentration (50 g/L) and initial solution pH 5. The kinetic study indicated that the adsorption metal follows pseudo-second order model for a multielementary system and equilibrium time was achieved in 60 min for all metal ions.

The Problem Based Learning (PBL) can be used as a strategy for methodological change in conventional learning environments. In this paper, the integration of laboratory work in PBL grounded activities during an introductory organic chemistry course is described. The most decisive issues of their implementation are discussed. The results show how this methodology favours the laboratory work contextualization in subject-matter and promotes the Science-Technology-Society-Environment relationships. Besides, it contributes to competence development like planning and organization skills, information search and selection, cooperative work, etc., the same way as the tutorial action improvement.

O presente ensaio analisa a relação entre arte e política a partir da sua autonomia recíproca, definida como um pressuposto epistemológico para o estudo daquela relação. Analisaremos como as especificidades ontológicas da arte (nos planos da recepção, da produção e do seu entrelaçamento entre semântica e sensorialidade) podem propiciar acontecimentos de caráter político, e também como tais especificidades podem se conciliar com a atividade crítica ou judicativa de vocação política, de maneira que elas sejam respeitadas, e não agredidas. Conforme argumentaremos, uma filosofia que bem se presta a esta função é a de Deleuze e Guattari. Porém, para que a sua importância fique clara, este ensaio será quase integralmente dedicado a expor os estilemas conceituais, cuja longa vigência na tradição filosófica dificultou, ao fim e ao cabo, que a reflexão sobre arte e política escapasse à ação normativa (que se revela na posição tutorial do filósofo quanto à ação do receptor e, muitas vezes, também na compreensão que ele faz do objeto "arte"). Pretendemos que o contraste entre o rigor destes estilemas, e a flexibilização que eles recebem em Deleuze e Guattari, sugira a obra destes últimos como uma via para a reversão do quadro normativo.

Necrotrophic parasites of above-ground plant parts survive saprophytically, between growing seasons in host crop residues. In an experiment conducted under field conditions, the time required in months for corn and soybean residues to be completely decomposed was quantified. Residues were laid on the soil surface to simulate no-till farming. Crop debris of the two plant species collected on the harvesting day cut into pieces of 5.0cm-long and a 200g mass was added to nylon mesh bags. At monthly intervals, bags were taken to the laboratory for weighing. Corn residues were decomposed within 37.0 months and those of soybean, within 34.5 months. Hw main necrotrophic fungi diagnosed in the corn residues were Colletotrichum gramicola, Diplodia spp. and Gibberella zeae, and those in soybeans residues were Cercospora kikuchii, Colletotrichum spp, Glomerella sp. and Phomopsis spp. Thus, those periods shoulb be observed in crop rotation aimed at to eliminating contaminated residues and, consequently, the inoculum from the cultivated area.

Trata-se de um de relato de experiência dos monitores bolsistas e voluntários de alguns cursos da área de saúde da Universidade Federal de Minas Gerais (UFMG) no projeto PET-Saúde, sob supervisão de cinco preceptores e de um tutor do projeto realizado na Unidade Básica de Saúde (UBS) Cafezal. O objetivo é descrever a experiência desse grupo tutorial do PET-Saúde Cafezal na promoção de hábitos saudáveis de vida. Os monitores puderam vivenciar a rotina do serviço de Atenção Primária, através do acompanhamento de diferentes atividades em diversos setores da UBS Cafezal e perceberam que os aspectos mais relevantes do projeto foram o trabalho interdisciplinar e multiprofissional, de acordo com os princípios de respeito e ética, a observação da rotina e do funcionamento da UBS, bem como a oportunidade de aplicarem seus conhecimentos acadêmicos adquiridos previamente. O modelo utilizado como estratégia de ensino-aprendizagem permitiu-lhes um meio de aprendizado teórico-prático dos preceitos adotados pelo SUS, uma vez que, devido ao princípio da indissociabilidade entre extensão, ensino e pesquisa, são realizados diversos trabalhos em campo e desenvolvidas pesquisas com equipes multidisciplinares.
