Avaliação ecotoxicológica de efluentes industriais utilizando Danio rerio Hamilton-Buchanan, 1822 (TELEOSTEI, CYPRINIDAE)

The industrial effluents are one of the main sources of water pollution. For an appropriate characterization and control of their discharges, the most efficient strategy is the integrated use of chemical, physical and ecotoxicological analyses. The aims of this study were to asses the efficiency of the treatment plant of a textile industry performing acute toxicity tests and physical-chemical analyses of the effluents before and after the treatment, besides evaluate the toxicity of the effluents of the Treatment System of Liquids Effluents (Sistema de Tratamento de Efluentes Líquidos - SITEL) of Distrito Industrial de Natal (DIN) and some of their physical-chemical variables. The species used in the ecotoxicological tests was the fish Danio rerio. The results showed that the treatment plant reduced significantly (around 50%) the toxicity of the raw textile effluent in only three of the seven tests but, in general, it promoted the reduction of the physical-chemical parameters analyzed. The toxicity and the physical-chemical factors of the effluents of SITEL of DIN varied among the tests and show the importance of monitoring their discharges in the Potengi river, one of the most important rivers of the Rio Grande do Norte state

Investigação e avaliação da toxicidade aguda dos agrotóxicos mais utilizados no cinturão verde da Grande Natal (RN, Brasil) para o peixe-zebra (Danio rerio Hamilton Buchanan, 1822, Teleostei, Cyprinidae

The objectives of this research were to investigate the agrotoxic most used in the Gramorezinho region in the green belt of Natal, and to evaluate the acute toxicity of these, based on the LC50-48h values estimated in tests for Danio rerio, internationally used as test organism. The acute toxicity tests were performed under laboratory conditions, according to standardized methods (ABNT/NBR/15088/04) for this species. The LC50-48h estimated to Tamaron BR was 352.89 mg.L-1, which characterizes that as practically non-toxic, according to toxicological classes cited by Zucker. For Decis 25EC, the LC50-48h estimated was 0.0004156 mg.L-1 (4.156 X 10-4 mg.L-1), which classifies it as highly toxic to this species

A Boneca Emília: por uma pedagogia performática

La investigación parte de una visión histórica de la muñeca Emília creación del escritor Monteiro Lobato , relacionándola con la educación en cuanto pedagogía performática. Utiliza aportes teóricos de Renato Cohen, investigador brasileño del lenguaje performático, como también del pensador y pedagogo alemán Nietzsche, aplicándolos a las obras Emília en el país de la Gramática, Aritmética de Emília y La llave del tamaño. Muestra que lo performático tiene sus orígenes más remotos en el mito de Dioniso y que, a semejanza del arte performática, propuesta como arte de frontera, la pedagogía performática se constituye también como una pedagogía de frontera, en vista de lo híbrido pedagogía-y-arte en que es fundado, colocándose igualmente en el espacio de las pedagogías culturales o no formales. Dentro del concepto de pedagogía performática, llegamos a la construcción de un pequeño sistema pedagógico que subraya tanto lo existencial cuanto lo científico. La pedagogía performática representada por la muñeca Emília contesta a la condición bidimensional del ser humano: razón y sensibilidad. Por hacer mediante una alianza con el arte en este caso, la literatura -, es más sugestiva que prescritiva; está apta a colaborar para el surgimiento de un paradigma pedagógico no-centrado en la hegemonía de lo racional; tiene um carácter atemporal y universal, pudiendo ser aplicada en todos los niveles de enseñanza, no se ha restringido, sin embargo, al espacio escolar

Educação escolar para crianças: o que dizem sujeitos deste direito?

The text aims to discuss the problems that this would be set: - What are the concepts of public school children about their right to primary education, as required step in the Basic Education? - What are conducted by children on the elementary school, in terms of its structure, teaching, and acquisitions provide for their users, especially when it comes to literacy? In order to answer these questions, we conducted within the qualitative a case study within twenty children of the early years of elementary public school, ten of the School Mauricio de Sousa and ten children of the School Monteiro Lobato. with construction procedures of data, we worked with observation, semi-directive interview, questionnaire and document analysis. In analyzing the data, two categories emerged: right to education and school for children. The first focuses on what children think about the legal guarantee to school, seeking to understand if they understand the educational area as a right and relate what the law says and the reality in which they participate. The category for school children, including their purposes, characteristics, space literacy and its relationship with the teacher. In this sense, we comment, taking as its founding, the speech of children in their schools, focusing on how they perceive the school in terms of its structure and functioning, relations with the knowledge and the other children. With regard to child rights, the appreciation of Brazilian children should be the basis of the struggle for a more just, democratic, nondiscriminatory. However, children show not recognize education as a right, but as one who deserves the credit, that is, those children who are always attentive, do not fight and do not complain. In interviews, children express a simple wish child that the school had toys. A school for children should be a place with its own characteristics: cheerful, lively, colorful, which included the same time, security and challenges. Children point to the hope that the course of action the teacher was guided by respect their differences in a more emotional, especially with regard to issues of authority and discipline of the group. The most important learning is for all subjects learning to read / write, differing in the idea of how to learn. Unfortunately, for some students, learning reading and writing appears as a difficult and enjoyable process is not perceived by some subjects up to recognize the instrumental writing. Finally, we point to the actors of the school to launch a more accurate to say that the children and how to outline your main locus of learning

Memórias de uma Escola Isolada Rural: estudo de um Livro de Visitas (1928-1948)

Cet article étudie le livre de visites de l'ancienne école mixte de la Fazenda Ponte Alta/Bela Vista, liée au groupe scolaire de la ville de Bariri, dans l'état de São Paulo (SP). À partir des registres de vingt ans d'activités (1928-1948), nous retraçons les exigences des inspecteurs primaires et si ces exigences provenaient (ou non) de professeurs et de la communauté paysanne pour ébaucher un cadre socio-historique de l'enseignement des premières lettres dans la zone rurale de l'intérieur de l'état de São Paulo. Il en résulte que le discours qui défendait l'égalité de chances pour les populations urbaines et rurales négligeait généralement le besoin de promouvoir l'égalité de conditions pour que la communauté rurale puisse profiter des chances qui lui étaient promises.

Taxonomia e biogeografia da espécie politípica Herpsilochmus rufimarginatus (TEMMINCK, 1822) (Aves: THAMNOPHILIDAE)

The genus Herpsilochmus is composed mainly of cryptic species, among them is Herpsilochmus rufimarginatus, which is currently represented by four subspecies: H. r. rufimarginatus, H. r. frater, H. r. scapularis and H. r. exiguus. Differences in plumage and vocalization suggest that there are more than one species involved in this complex. Thus this and other subspecific taxa need urgent revision, the disjunct distribution of this species also allows us to infer the relationship between birds that occur in this biome and / or different centers of endemism. This study aims to make a taxonomic revision of the taxa included in the complex time Herpsilochmus rufimarginatus based on morphological, morphometric, vocals and geographical distribution of this bird. Besides creating distribution models current potential and make the reconstruction of the distribution bygone using ecological niche modeling, and testing the niche conservatism and divergence between different subspecies. Consultations for examination of the skins of specimens of the museums: Museum of Zoology, University of São Paulo (MZUSP), National Museum of Rio de Janeiro (MN) and Emilio Goeldi Museum of Pará (MPEG), and the skins deposited at the collection of Ornithological Federal University of Rio Grande do Norte (COUFRN). We studied the following measures length of specimens: exposed culmen, culmen and total culmen nostril, tarsus, wing and tail flattened. The voice analysis was performed with vocalizations banks and / or digital banks people where 17 voice parameters were measured. This information and more available in the literature were used to assemble a bunch of data under the limit distribution of taxa and generate ecological niche models. This analyzes carried out in the program Maxent, having as model selection criterion the AUC, and the models were greater than 0.80 are considered good models. Environmental data for the realization of the modeling were downloaded on the website of Worldclim. The morphometric information, vocals and geographic distribution point for the separation of these taxa to be considering various uni and multivariate analyzes. The potential distribution models performed well (AUC> 0.80), and its distribution associated with environmental characteristics of the Amazon forest and Atlantic forest (forests of south and southeast, northeast and forest). The reconstruction of the distribution indicates a possible contact between the southern part of the Atlantic forest in the northern part of the Amazon. The analysis of niche overlap showed a low overlap between taxa and comparisons between the null model and the generated overlay link probably occurring niche conservatism. The data suggest that the taxa that occur in the Amazon and Atlantic forest represent three distinct species

Poder local e o funcionamento do comércio vicinal na cidade de São Paulo (1765-1822)

Este texto apresenta algumas hipóteses e idéias sobre o comércio de abastecimento da cidade de São Paulo, entre os anos 1765-1822, através de dados quantitativos e qualitativos levantados em dois conjuntos documentais produzidos pelo Senado da Câmara: Atas e Papéis Avulsos. Este comércio é entendido como um dos circuitos do organismo colonial, conforme proposto por José Roberto do Amaral Lapa. Neste sentido, vem sendo constatado seu funcionamento autônomo, de acordo com os fluxos do mercado interno, as ações dos negociantes-arrematadores de contratos e as reações do Senado da Câmara de São Paulo para enfrentar seus contextos de crise e a radicalização de relações de poder em torno deste circuito mercantil, como fator desencadeador de disputas e hostilidades entre interesses políticos locais, negociantes-arrematadores e autoridades régias.

Subsistemas de comércio costeiros e internalização de interesses na dissolução do Império Colonial português (Santos, 1788-1822)

Discutem-se os primeiros resultados de uma pesquisa sobre o comércio costeiro e suas relações com o funcionamento do sistema colonial e com o contexto da Independência. A tese é de que em portos menores da costa da capitania de São Paulo, como em Santos, havia um grupo de comerciantes que atuava efetivamente no comércio costeiro e defendeu seus interesses de exclusividade de participação nesse setor contra a presença de comerciantes externos à vila. A discussão apoia-se em documentos da alfândega de Santos, como mapas de exportação-importação, mapas de embarcações, ofícios de governadores e juízes da alfândega e requerimentos de negociantes estrangeiros.

O império da lei: ensaio sobre o cerimonial de sagração de D. Pedro I (1822)

Ce texte analyse le cérémonial royal de la monarchie constitutionnelle brésilienne: le sacre et le couronnement de l'Empereur D. Pedro I. Notre examen de ce cérémonial a comme point de départ son caractère liturgique, pour comprendre pourquoi cet aspect a été considéré essentiel alors pour affirmer l'autonomie du nouveau royaume et, en même temps, a contribué pour définir le pouvoir politique de l'Empire du Brésil.

Utilization of shells of the snail Achatina fúlica Bowdich, 1822 (Mollusca, Gastropoda) by the hermit crab Clibanarius vittatus (Bosc, 1802) (Decapoda, Anomura) in the São Vicente Estuary, São Paulo, Brazil

Hermit crabs depend on mollusc shells for housing. In this study, an unusual resource is reported for a hermit crab that usually inhabits marine gastropod shells. During a field study conducted from May 2001 to April 2003 in an estuarine area in São Vicente, state of São Paulo, Brazil, 21 individuals of Clibanarius vittatus (Bosc, 1802) were found inhabiting the shells of the terrestrial gastropod Achatina fullea Bowdich, 1822. A. fúlica occurs in nearshore grass patches, where occasional contact with sea water kills them, and their shells then become available to the hermit crabs.
