António Nobre e o simbolismo em Portugal

Nesta dissertação são analisados alguns poemas de Só com o intuito de tentar compreender e verificar eventuais contributos de António Nobre para o Simbolismo em Portugal. Ao longo da nossa investigação, daremos uma particular atenção a alguns dos temas mais recorrentes na obra de António Nobre: a Solidão, a Angústia e a Morte. Sabemos que existem outras temáticas sobre as quais faremos uma breve referência; contudo, por se tratar de um vasto campo de possibilidades, limitámos o número de temas a desenvolver no presente trabalho. Veremos de que modo a última década do século XIX foi marcada, no continente Europeu, por um movimento de reação ao cientismo e ao naturalismo, bem como ao ambiente espiritual surgido em Portugal pelas mãos dos «Vencidos da Vida», cujo especial relevo terá sido atribuído a António Nobre. Verificaremos de que modo Só poderá emergir como uma obra de cariz confessional tendo tido na época o objetivo de abalar os cânones tradicionais em vigor. Só apresenta-se, entre outras possibilidades, como a expressão da história de fracassos e de fadigas do povo lusitano que cultiva o sentimento amargo da saudade, uma obra que dá a ver o retrato de Portugal do século XIX e, assim, a identidade do povo que vê Portugal decair.

Uma comparação da aptidão funcional de mulheres idosas portuguesas e brasileiras

O objectivo deste estudo transversal foi descrever e comparar os perfis funcionais de duas amostras: 401 idosas portuguesas e 967 brasileiras (Krause et al., 2009), dos 60-79 anos. A aptidão funcional (ApF) foi avaliada usando a bateria Senior Fitness Test (Rikli & Jones 2001). Em ambas as amostras, as idosas dos 60-64 anos apresentaram melhores desempenhos na maioria dos testes de ApF, comparativamente às dos 75-79 anos. As idosas brasileiras foram mais proficientes na aptidão cardio-respiratória e flexibilidade, e as portuguesas, na força do membro superior. Os valores do índice de massa corporal foram superiores nas idosas portuguesas (60-79 anos). Estes resultados poderão ser úteis na identificação precoce de perdas funcionais, e fundamentar a intervenção ao nível da ApF em mulheres idosas.

Allergic asthma exhaled breath metabolome: a challenge for comprehensive two-dimensional gas chromatography

Allergic asthma represents an important public health issue, most common in the paediatric population, characterized by airway inflammation that may lead to changes in volatiles secreted via the lungs. Thus, exhaled breath has potential to be a matrix with relevant metabolomic information to characterize this disease. Progress in biochemistry, health sciences and related areas depends on instrumental advances, and a high throughput and sensitive equipment such as comprehensive two-dimensional gas chromatography–time of flight mass spectrometry (GC × GC–ToFMS) was considered. GC × GC–ToFMS application in the analysis of the exhaled breath of 32 children with allergic asthma, from which 10 had also allergic rhinitis, and 27 control children allowed the identification of several hundreds of compounds belonging to different chemical families. Multivariate analysis, using Partial Least Squares-Discriminant Analysis in tandem with Monte Carlo Cross Validation was performed to assess the predictive power and to help the interpretation of recovered compounds possibly linked to oxidative stress, inflammation processes or other cellular processes that may characterize asthma. The results suggest that the model is robust, considering the high classification rate, sensitivity, and specificity. A pattern of six compounds belonging to the alkanes characterized the asthmatic population: nonane, 2,2,4,6,6-pentamethylheptane, decane, 3,6-dimethyldecane, dodecane, and tetradecane. To explore future clinical applications, and considering the future role of molecular-based methodologies, a compound set was established to rapid access of information from exhaled breath, reducing the time of data processing, and thus, becoming more expedite method for the clinical purposes.

Análise de bacias de retenção

A presente dissertação tem por objetivo o estudo da construção de bacias de retenção de águas pluviais como solução para o controlo do escoamento superficial urbano. Pretende-se estudar e definir os fatores necessários ao dimensionamento de uma bacia de retenção, bem como abordar aspetos técnicos da complexa análise hidrológica e hidráulica necessários à correta avaliação da distribuição temporal e espacial da precipitação, e consequente escoamento em tecido urbano. Descrevem-se os tipos e funcionalidades das bacias de retenção, dando particular ênfase ao dimensionamento das mesmas na própria área a urbanizar, pela previsão do volume de armazenamento necessário, em função da rede de drenagem pluvial existente ou a construir, dada a heterogeneidade dos fatores que determinam o seu dimensionamento para horizontes de projecto longos, e tendo em conta que os custos associados a um sobredimensionamento poderiam inviabilizar o investimento.

Inovação pedagógica em busca de mudanças qualitativas no ensino fundamental I

Esta pesquisa tem como título Inovação Pedagógica em Busca de Mudanças Qualitativas no Ensino Fundamental I, com o objetivo de investigar a prática pedagógica no sentido de identificar a existência ou não de inovação pedagógica, no âmbito da Escola de Ensino Infantil e Fundamental Trilha do Saber, situada no município de Guaraciaba do Norte/Ceará/Brasil. A universalização da pesquisa se dá com foco nas interações entre professora e alunos e destes entre si. Os sujeitos desta investigação são os alunos e a professora do 3º ano, turma B, do Ensino Fundamental I. O referencial teórico utilizado nesta investigação tem como base os estudos de Fino a partir de (1999), Fino & Sousa desde (2005); Papert (1980, 1993, 2008); Vygotsky (2007); Perrenoud (2000); Freire (1979, 1985, 2011); Mendonça (2009, 2010); Toffer (1997); Gadotti (2006, 2008); Piaget (2010); Salviane (2009) e outros teóricos, que fundamentam concepções de prática pedagógica inovadora. Esta pesquisa com foco na aprendizagem, nos alunos e nos contextos de aprendizagem é de natureza qualitativa e estudo de caso, segundo a orientação de Yin (2001), Silva (2009), Macedo (2006, 2008); Alvarenga (2010) e Lapassade (2005), uma vez que esse processo de investigação permite a utilização de diversos instrumentos de coleta de dados; utilizou-se a observação participante e a entrevista semiestruturada, favorecendo o cruzamento dos dados (triangulação) no procedimento de análise e discussão dos resultados. Concluiu-se, que a escola deve ser um espaço aberto às mudanças e indagações dos alunos compondo-se dos aspectos criativo, dinâmico e inovador assegurando aos aprendizes novos contextos de aprendizagem situada. Concluiu-se, ainda, nesta investigação, que é mais difícil a inovação pedagógica acontecer nas escolas públicas em razão da inclusão de programas e projetos que são implantados pelas políticas educacionais.

Povoações, freguesias e vilas na Paraíba Colonial: Pombal e Sousa, 1697-1800

The towns presently named Pombal and Sousa, located in the hinterland of the State of Paraíba, Brazil, still keep vestiges of the colonization process they went through along the 18th and 19th centuries, when they both emerged as settlement nuclei in the extreme West of the then captaincy of Paraíba and attained the status of freguesia and vila in a later period. This research aims to comprehend the process of urban formation and development of the colonial urban nuclei of Pombal and Sousa as they became povoados (hamlets), freguesias (parishes) and vilas (small urban communities with a local government), according to territorial expansion policies implemented by the Portuguese government from 1697 to 1800. The choice of the two urban settlements for this survey lies in the fact that they were part of the great conquest and colonization program undertaken by the Portuguese Crown. Another aspect that was considered was the fact that those towns are the oldest urban nuclei of Paraíba s hinterland. They came into being as early as in the times of the colony, thus producing a favorable environment to the study of the changes that occurred in the captaincy s hinterland scenery resulting from the process of formation and development of the colonial urban space. Three fundamental categories of analysis were defined since they have a direct bearing upon the urban configuration of the two colonization nuclei: povoado, freguesia and vila. The three of them are related to civil and ecclesiastic jurisdictions. Field, documentation and bibliography surveys were undertaken in order to develop the study. They allowed for the finding of vestiges of the old, colonial urban structures and for the development of theoretical analysis based on present-day studies of issues relating to the colonial urban history. The study purposes were, therefore, to try to understand how the old urban nuclei of Pombal and Sousa fit in the territorial expansion policies undertaken by the Portuguese government; to relate the process of urban formation and development of such nuclei with the categories of analysis povoação-freguesia-vila by discussing the relations and influences they exert over one another and their territory, as well as to unveil, as much as possible, the configuration the urban spaces that were shaped along the 18th century

O processo de urbanização de Mossorò: dos processos históricos à estrutura urbana atual

The general objective of this academic work is to analyze the relationship between the territorial division and the urban expansion process of Mossoró city, understood here as the production and occupation of space. The urban expansion in Mossoró, since its formation as settlement in 1772 until current days, identifies with the Brazilian urbanization process whose growth is determined by the capitalist development. Thus, the expansion was determined by several economical specializations imposed by the territorial division of work which occurs at an interregional level, and, sometimes at an international level. Then, each specialization determined a moment of the urban expansion of the city, as follows: a) The cattle farmer specialization, between 1772 and 1857, when the urban expansion was shy, is summarized to a commercial square that received goods from Aracati aiming to cover a wide rural area; b) The commercial emporium specialization, between 1857 and 1930, when the urban expansion took an important impulse with the concentration of public and private capitals; c) The salt industry and the agricultural-industrial exporter specialization inside a state of development policy, between 1930 and 1970, when the urban expansion, joined to the settlement of the working class in the urban soil, developed along an important axis -the railway; d) The render of services specialization inside a state of intervention policy, between 1970 and 1990, when the urban expansion was characterized by the accelerated growth rhythm, by the reuse of some spaces, and by space segregation of demanding people; e) The render of services policy inside a neoliberal state policy, since 1990 until current days, when the urban expansion reduced its rhythm abruptly, when only small alterations occurred in the existing spaces. It focused on social policies and on several slums eradication programs. Finally, the territorial structure is deeply articulated with others, no territorial, but economical, social and political, which happens at a national, regional and local rate. Only within a historical and conceptual panorama, it was possible to explain the urban expansion in Mossoró from its formation in 1772 until current days. Therefore, this work is a several discipline analysis of the urbanization process existing in Mossoró

Síntese e caracterização de catalisadores nanométricos de LaSrNiO4 para aplicação em dessulfurização de tiofeno

The mixed metal oxides constitute an important class of catalytic materials widely investigated in different fields of applications. Studies of rare earth nickelates have been carried by several researchers in order to investigate the structural stability afforded by oxide formed and the existence of catalytic properties at room temperature. So, this study aims synthesize the nanosized catalyst of nickelate of lanthanum doped with strontium (La(1-x)SrxNiO4-d; x = 0,2 and 0,3), through the Pechini method and your characterization for subsequent application in the desulfurization of thiophene reaction. The precursor solutions were calcined at 300ºC/2h for pyrolysis of polyester and later calcinations occurred at temperatures of 500 - 1000°C. The resulting powders were characterized by thermogravimetric analysis (TG / DTG), surface area for adsorption of N2 by BET method, X-ray diffraction (XRD), scanning electron microscopy (HR_SEM) and spectrometry dispersive energy (EDS). The results of XRD had show that the perovskites obtained consist of two phases (LSN and NiO) and from 700ºC have crystalline structure. The results of SEM evidenced the obtainment of nanometric powders. The results of BET show that the powders have surface area within the range used in catalysis (5-50m2/g). The characterization of active sites was performed by reaction of desulfurization of thiophene at room temperature and 200ºC, the relation F/W equal to 0,7 mol h-1mcat -1. The products of the reaction were separated by gas chromatography and identified by the selective detection PFPD sulfur. All samples had presented conversion above 95%

Biodegradação de hidrocarbonetos aromáticos policíclicos: prospecção metagenômica e modelagem computacional 3-D de proteínas

Knowledge of the native prokaryotes in hazardous locations favors the application of biotechnology for bioremediation. Independent strategies for cultivation and metagenomics contribute to further microbiological knowledge, enabling studies with non-cultivable about the "native microbiological status and its potential role in bioremediation, for example, of polycyclic aromatic hydrocarbons (HPA's). Considering the biome mangrove interface fragile and critical bordering the ocean, this study characterizes the native microbiota mangrove potential biodegradability of HPA's using a biomarker for molecular detection and assessment of bacterial diversity by PCR in areas under the influence of oil companies in the Basin Petroleum Geology Potiguar (BPP). We chose PcaF, a metabolic enzyme, to be the molecular biomarker in a PCR-DGGE detection of prokaryotes that degrade HPA s. The PCR-DGGE fingerprints obtained from Paracuru-CE, Fortim-CE and Areia Branca-RN samples revealed the occurrence of fluctuations of microbial communities according to the sampling periods and in response to the impact of oil. In the analysis of microbial communities interference of the oil industry, in Areia Branca-RN and Paracuru-CE was observed that oil is a determinant of microbial diversity. Fortim-CE probably has no direct influence with the oil activity. In order to obtain data for better understanding the transport and biodegradation of HPA's, there were conducted in silico studies with modeling and simulation from obtaining 3-D models of proteins involved in the degradation of phenanthrene in the transport of HPA's and also getting the 3-D model of the enzyme PcaF used as molecular marker in this study. Were realized docking studies with substrates and products to a better understanding about the transport mechanism and catalysis of HPA s

Teodora e Porcina: faces simbólicas da natureza em narrativas de mulheres sábias

This research looks at the collective imagination in which it keeps alive the issue of heroin wise. Two wise women appear in the narratives of popular history and the History of Donzela Theodora and History Imperatriz Porcina, collated by Luís da Câmara Cascudo in his Five Books of the People. The universality, mobility and circularity of these narratives are discussed by authors such as Bakhtin and Guinzburg. The research is developed from three key categories: Knowledge Magic as the knowledge of tradition (Almeida), sensitive knowledge (Levi-Strauss), thought mythical / magical / symbolic (Morin); Wise Women as carriers of this knowledge, which merge and overlap with the imagery of witches and healers; and Mythical Elements which corresponds to the archetypal images (Jung and Silveira), symbols and other images that relate to the magic universe, the magical beliefs and practices considered, ie belonging to the imaginary magic (Bethencourt). Porcina and Theodora are understood as bearers of knowledge of Métis (Detienne and Vernant), or the cunning intelligence, the manipulation of phármakon (Derrida), the healing potion, which may be the word or ointment of the herb. The route takes us to meet the great archetype of the Wise Woman as psychic power of the feminine, the anima. Narratives are medicinal balms (Estes) and is the clash between the anima and its embodiments by wise women, and animus, his opponents, which gives the transmutation of the psyche, a work comparable to that of alchemyThe Knowledge Magic, operating through the female, myth and nature can recover from its essential value to the emerging paradigm that suggests a more complete human science and a more plural

Tornar-se, ser e viver do professorado: entre regularidades e variações identitárias

The main aim of this research has been to analyze the identity patterns of the teacher s staff of fundamental education public schools in the Metropolitan Area of Natal-RN. It sets out from the hypothesis that being a teacher within this context grows out of the regularities of a specific habitus, which, according to Bourdieu, develops into mental schemes of thought and action within a specific social group. This habitus forms the basis on which is built the social representation of being a teacher prevailing in the group, as well as the symbolic differences that typify its identity variations. Three data sources have been fundamental in building up this thesis: (a) formative essays of students graduating from a Higher Teacher s Formation Course, as well as observing some of the public defense of these essays during field work; (b) a questionnaire aimed at classifying economically, socially, and culturally a sample of public teachers of the Natal-RN county; and (c) submitting a sub-sample of this group to the process of Multiple Classification Procedures (MCP). The analysis of data was done according to the multidimensional, non-parametric statistical procedures of both the Category Content Analysis and Enunciation Analysis methods. The results of the analysis took into account an ample set of variables, its associations and implications, the cultural and social profile of the population under scrutiny, their life styles, as well as the strategies they developed in the process of becoming a teacher, and the social representation of being a teacher . We came to the conclusion that the social identity of the teachers corps, or as we prefer to say it being a teacher , is a result of a set of regularities produced by the habitus that gives social shape and meaning to the existence of the group proper. We note the existence of identity variations caused by the variables (a) educational level; and (b) mode of action in fundamental education (if these are the first or last grades where the subjects operate). However, these variations will not break the power of the regularities that give shape, meaning, and social visibility to the group. The social representation of being a teacher points to the tensions, ambiguities, and trends inherent to common sense, as well as to a strong tendency to reassign a new meaning to being a teacher. Our thesis, therefore, is that the identity configuration of the teachers corps under scrutiny is characterized by an integrative synthesis, by-product of a habitus that is superimposed, and at the same time co-exists with different identity variations

Histórias de leituras e de leitores: práticas e representações de leitura em narrativas de professores de diferentes disciplinas escolares

Nous avons pris comme point de départ le préssuposé que en exerçant ses practiques de lecture en salle de classe, les professeurs récuperent des signes de ses expériences socioculturelles par rapport à la lecture, construites au long de ses trajectoires. Indépendemment de sa discipline scolaire, la mémoire de ces expériences interviennent certainement, de manière positive ou négative, dans la médiation de la formation de l élève lecteur. C est donc, par l articulation entre les perspectives de ses études qui parlent sur l histoire de la lecture, narratives (auto)biographiques et formation du professeur que je prétends récupérer et reconstruire, par les narratives de lectures racontées par les professeurs de différentes disciplines scolaires, les processus d appropriation de la lecture en considérant ses tactiques d accès et d utilisation des matériels écrits en circulation dans les groupes sociaux auxquels ils appartennaient. Pour ça ce travail s inquérit : Quels models de lectures émergent dans les narratives de professeurs de différentes disciplines scolaires ? Comment se manifestent-elles les représentations sur sa performance pour la formation de l élève lecteur ? L objectif central est d inférer les rapports existants entre des expériences de lecture et la médiation dans la formation de lecteurs. Douze professeurs de l éducation de base des écoles de la ville de Belém y ont participé. Le corpus est constitué par les transcriptions de deux genres d instruments: douze interviews narratives et deux groupes de débats. Les analyses montrent deux grandes fases de la rencontre avec la lecture : une antérieure à l école et l autre à partir de l école. Ces fases montrent des pratiques et des représentations de lecture hétérogènes différenciés par rapport à ses aspects fonctionnaux. Elles revellent encore que la formation du lecteur professeur et élève se lie, d abord, à la constitution culturelle de l homme, marquée, fondamentalement, par son interlocution avec l autre. La famille, l école et le lieu de travail se présentent comme des espaces qui impriment des marques profondes dans le rapport avec la lecture. Malgré ça, le même matériel écrit, un fois mis en scène le lu dans ces espaces n ont pas de significat coincidents pour les différentes personnes qui s en approprient. Cette raison montre la possibilité de la construction d une histoire de la lecture, basée pas exclusivement à la description des matériels lus pendant le cours de leurs vies, mais surtout, sur les indicateurs de ses différentes manières de lire. Cette trajectoire exerce de cette façon une forte influence sur la prise de décision et les manifestations du travail du professeur en situation de salle de classe. Comme ça on peut conclure, premièrement, que les représentations et pratiques de lecture se sont constitués et se sont (re)configurés dans des différentes formes, concepts, temps et espaces, dans un entrecroisement de différents discours. Deuxièmement que la reflexion sur les mémoires de lecture a resulté un nouveau regard des participants sur son travail de professeur et a confirmé l hipothèse selon laquelle la production des narratives autoréférencées offre, à qui les narre, la possibilité de transformation des représentations du sujet avec lui-même, avec l autre et avec le monde, ce qui démontre l importance de la recherche (auto)biographique comme méthode d investigation en éducation et sa contribuition pour la formation des formateurs de lecteurs dans des différents domaines de la connaissance , comme territoires constitutifs du sujet et de ses pratiques sociales, à l école et ailleurs

Aí eu era Antônio Brasil: contribuições de situações didáticas com conhecimentos históricos para a construção da identidade pessoal da criança na educação infantil

L'objectif de cette étude est de comprendre la relation entre les situations didactiques faisant appel aux connaissances historiques et la construction de l'identité personnelle pour les enfants dans l'éducation de la petite enfance. Sa question centrale se demande si les connaissances sont offrent des contributions à la construction de l'identité personnelle par les enfants de la petite enfance. Se distingue, lui aussi, entend contribuer à élargir le débat sur l'enseignement et l'apprentissage des thèmes historiques dans l'éducation des enfants, et permettre un dialogue avec d'autres enseignants dans cette étape de l'éducation. Ont été analysés par des principes théoriques et méthodologiques de qualité et a assumé les orientations méthodologiques de la recherche collaborative. Il a été constaté que la systématisation des situations didactiques impliquant la connaissance historique dans l'éducation de la petite enfance contribue à la construction de l'identité personnelle de l'enfant. Ceci, pour prendre possession de ces connaissances, ils recueillent des renseignements qui permet le plus large éventail de relations, afin de comparer les pratiques culturelles de son temps avec des pratiques à d'autres moments. Ainsi orientée, l'enfant cherche à raconter son histoire avec le thème historique à laquelle elle a eu accès, d'organiser et de construire des réponses des explications sur leur environnement et de lui-même. Tout cela montre à la réalisation que le processus d'internalisation des connaissances historiques de l'enfant est construit comme un sujet et, par conséquent, cette connaissance peut être conçu comme un médiateur dans la formation de l'identité personnelle
