Otimização Topológica com Termo-elasticidade Utilizando Elementos Tri3

This work proposes a formulation for optimization of 2D-structure layouts submitted to mechanic and thermal shipments and applied an h-adaptive filter process which conduced to computational low spend and high definition structural layouts. The main goal of the formulation is to minimize the structure mass submitted to an effective state of stress of von Mises, with stability and lateral restriction variants. A criterion of global measurement was used for intents a parametric condition of stress fields. To avoid singularity problems was considerate a release on the stress restriction. On the optimization was used a material approach where the homogenized constructive equation was function of the material relative density. The intermediary density effective properties were represented for a SIMP-type artificial model. The problem was simplified by use of the method of finite elements of Galerkin using triangles with linear Lagrangian basis. On the solution of the optimization problem, was applied the augmented Lagrangian Method, that consists on minimum problem sequence solution with box-type restrictions, resolved by a 2nd orderprojection method which uses the method of the quasi-Newton without memory, during the problem process solution. This process reduces computational expends showing be more effective and solid. The results materialize more refined layouts with accurate topologic and shape of structure definitions. On the other hand formulation of mass minimization with global stress criterion provides to modeling ready structural layouts, with violation of the criterion of homogeneous distributed stress

Ensino de matemática pelo rádio (1950 1970): uma história falada e um documentário didático

This study aimed to describe and analyze aspects of the historical course of teaching Mathematics by Radio Experiences in Rio Grande do Norte, between the decades from 1950 to 1970 in order to organize a documentary (CD-ROM) containing information about Mathematics studied by Radio who have experienced it. In this, we use qualitative research. We seek support in the theoretical framework of cultural history and memory researchers as Certeau (1998), Chartier (1990), Le Goff (2008), Thompson (2002) and Peter Burke (2004). Moreover, we take the elements of oral history. We focus on the teaching of literacy and the primary of the Radio schools in two rural communities - Logradouro and Catolé - who are currently part of the city of Lagoa Salgada (RN) and, with respect to the Junior High School, we stopped in the Course of Madureza at Radio. We used as written sources, especially the documents found in the General Archives of the Archdiocese of Natal (RN) and the employees assigned by the participants of the survey. Our sources come from the oral testimonies of pupils and monitors Lagoa Salgada City, teachers, broadcasters and technicians of Rural Support Service (SAR) Natal (RN). In this study, we identify the geometry Cubação social practices of Lagoa Salgada students. Also identified in the research material, the Global Method with the pedagogy of Paulo Freire, that guided the production of lessons in literacy and primary courses. Content in Mathematics, we find traces of the trend-Empirical activist. In the course of Madureza, there was a tendency formal technique Fiorentini (1995). Finally, as a result of this study, organize and present a documentary (CD-ROM), along with the analysis of this study, containing the history of Mathematics teaching by Radio, from the speech of those who experienced Radio, emphasizing the methodology teaching developed in class, that serves as a reference material for students, professors and researchers.

As Filhas do Arco-Íris, de Eulício Farias de Lacerda : mitos, lendas e contos populares como elementos estruturantes do romance

The corpus of this work constitutes an analysis the literary work As Filhas do Arco-Íris, by Eulício Farias de Lacerda, considering object of study myths, legends and popular stories as estruturant elements of the romance. The unchainment of this reading considers aspects of the oral tradition as starting point for the rupture tradition. In that perspective, it became fundamental to describe aspects of the popular culture that consolidated the Brazilian Literature during the 20th century. Like this, it was necessary to understand the development of oral elements and the structuring of the folk-tales, pointing out that As Filhas do Arco-Íris was built in a especial way with regionalist characteristics, following the parameters of the romances published among the years 1930 and 1950. In the researched work, it was noticed a narrative that gathers stories, legends, myths, proverbs and oral locutions. In this, it reveals that the Brazilian literary production grew in aesthetics and thematic. Like this, As Filhas do Arco-Íris is an exercise of the experience regionalist inserted in the contemporary novel, because even with your first publication in 1980, the narrative is configured to the molds of a Romance de 30

Citação e modernidade em Álvares de Azevedo: do sublime ao dessublime

El estudio de la citación en Lira de los Veinte Años, de Álvares de Azevedo, desde la óptica de Antoine Compagnon e Gerárd Genette, se muestra relevante a los estudios de la Literatura Comparada, en la perspectiva conteporánea, pués el tema provoca la posibilidad de discutir la elaboración de si del(los) otro(s), sucitando imágenes estéticas y de los pensamientos que se aproximan de una noción de tesitura textual muy presente en la modernidad literaria. Este proceso instaura procedimientos de lectura, traducción, autoria y escritura, aún, por ser utilizados, confirman la potencialidad inegable en que se escribi el trabajo poético del escritor. En la primer parte de la obra, se sugieren experiencias com lo bello y lo sublime, advindos del europeu, pero vuelto para una pesquisa de posibilidad discursivas. En la según parte, esa instancia sublimada es puesta en crise, por el sujeto poético cribado por el deseo de tornarse singular. Se instauran en el campo valorativo de los signos románticos elementos desfavorables de sentido diferentes. Dase, así, la problematización puesta por las citaciones que ora, realizan cambios simbólicos, ora, actuan en las márgenes de los textos primeros, desorganizando el material de autoria, desublimandolo, en la irrupción de nuevos cuerpos discursivos y cuerpúsculos cituacionales. En la tecer parte, ligado a Tánatos, como la dimensión por venir, marcando el presentimiento del poeta de que morirá temprano, como también la despedida de él. En esta tesi, se pretende, así, circunscribir como se figura, elabora esa constituición estética azevediana y su escritura, situando cuestiones recortadas por el actor en su obra, las quales remeten a Hegel, Kant y la otras lecturas filosóficas, ali puestas. Tal procedimiento toma la citación como estrategia poética de inscrición del sujeto y de las alteridades que le atravesan, concebiendo eso proceso autoral en la forma de reconstrución de una ciudadela de libros en este aspecto, considerandose el enfoque de Félix Guatarí, la propósito de los nuevos paradigmas y las espacialidades emergentes de estos -, o la biblioteca subjetiva, que se abre en vias y pasagenes. A través de ellas el discurso captura no solamente los objetos poéticos, pero también trazos autobiográficos rasurados, traduciendo la lucha por la visibilidad del sujeto en la formación de su pensamiento poético y estético

Cecília Meireles: mulher ao espelho, imaginário poético e metafísica do amor em Viagem e Mar Absoluto

En el florescer de la modernidad brasileña, surge la poesía de Cecília Meireles, revelando la mujer que opta conscientemente por la labor intelectual, por la especulación filosófica del amor y por la pasión de escribir. La lectura de su obra representa um desafío a la sensibilidad del estudioso de la literatura. En esta disertación, tratamos de ese trabajo em filigranas que la autora realiza. Nos situamos em las obras Viagem y Mar Absoluto como anclas simbólicas de un discurso que nos remite a la relación del poetar com el pensar. Se inserta, así, esa poética ceciliana en um modo filosófico platónico, trayendo elementos simbólicos, míticos, metafóricos capaces de remitirnos a las interpretaciones filosóficas del siglo XX, tal la heideggeriana que entiende la poesía dentro del principio del eterno juego del ser, que es lo del próprio lenguaje. Nuestra preocupación fundamental fue trillar los caminos del erostismo filosófico y la búsqueda de la autora em transcender la rigidez de los límites entre el masculino y el femenino, lanzándose em um imaginario poético cristiano, reinterpretado neoplatonicamente. Se exponen Mujer y Letras al espejo, velando y desvelando marcas e trazos de identidad. Tal juego especular nos ofreció elementos poéticos, estéticos y una experiencia ceciliana del lenguaje del ser, designio de la poesía mísma. De esta nuestra iniciativa, que es también reflejada y reflexiva, reunimos a las Letras la Filosofia, resaltando que ambas de manera diferente - nos dieron acceso a la construcción de esa poesía en que fulguran la escritura, el ser y la naturaleza metaforizada, caracterizando la multiplicidad de sentidos y la pluralidad de voces del presente y del pasado

Vestígios de permanência e mudança dos classificados do Jornal Tribuna do Norte (1951-2010)

The text, to be held in different linguistic spheres, in many aspects absorbs the changing processes through which language passes as a result of socio-historical changes. In this sense, this research proposes a study on gender sorted, motivated by the desire of understanding how the text incorporates traces of change and how to keep its constituents over time, in order to point out what are its characteristic traits. Our analysis is centered on the newspaper s section called classificados of Tribuna do Norte, state of Rio Grande do Norte, between the XX and XXI centuries. From the survey data a descriptive and analytical analysis was performed with a corpus of 250 listings, divided between the years 1951-2010. Based on a diachronic analysis, we also seek to investigate the macro-structural aspects of gender and microstructural compositional elements from the opportunities section that originated the Caderno de Classificados . For this reason, this approach has focused on particular Roman German Philology, especially in the works of Coseriu (1980) and Kabatek (2006). The analysis revealed that since its inception in Brazil, the classificados have fixed constituent elements, such as the use of "sell" and "rent" in the title or introduction, but also shows traces of change in the closure of the text, and especially with regard to the division of classificados by area of interest, that in the newspaper called Tribuna do Norte started in the Opportunities section

No céu da boca das gentes, tem estrela e maravilhas: atualização e permanência das narrativas populares nos contos de enganar a morte

This current study consists in an analysis of the work Contos de enganar a morte (2004), of the novelist, illustrator and researcher of popular culture Ricardo Azevedo, aiming to highlight aspects and elements present in this work which show the update and the permanence of traditional popular narratives, widespread by orality, especially those collected by the Luís da Câmara Cascudo in Literatura oral no Brasil (1984), linked to the category of the Cycle of the Death and Tales of the Deceived Demon. It is argued that the symbolic, playful, humor and aspects of orality, evident in these narratives are cultural possessions own of a popular tradition that diffuses, is updated and maintained by the memory of handmade anonymous narrators (BENJAMIN, 1994), poets and brazilian singers of cordel, holders of the traditional knowledge not established, but polyphonic, dialogical and democratic in essence (BAKHTIN, 1996). Still, alongside the people who know and counts the stories of Trancoso and Fairies, the tale, as a written literary genre, has allowed to maintain outstanding the same subjects successively renewed, enabling the resistance of popular narrative tradition and understanding and appreciation of popular orality (ZUMTHOR, 1993; 2000) and of the updates performed in the contemporarity (CANDIDO, 1976), without losing sight of the singularity and autonomy of the literary work

Entre a fé, a obra social e a publicidade: uma análise crítica do discurso da responsabilidade social da Igreja Universal do Reino de Deus

Situated on Applied Linguistics (PENNYCOOK, 1998; MOITA LOPES, 2003, 2006, 2008, 2009), this thesis, which is inscribed in a qualitative-interpretative approach of a critical analysis perspective , lies on the speech of social responsibility and the way like that is employed in seeking for legitimacy and prestige within the neopentecostal brazilian religious field, more specifically of the Universal Church of the Kingdom of God. The general goal of this research is t reflect upon the speech on social responsibility and the rethoric of selfpromotion of the Universal Church through the role of social actors in the making of his her identities, materialized in the newspaper Folha Universal. In order to achieve that, we have conjugated, in this research, social and discursive analysis. On the linguistic-discursive approach, the research is based on the Critical Analysis of Discourse (ACD), specially in Fairclough (2001, 2003, 2006), a proposal that provides theoretical-methodological tools to investigate the language beyond the linguistic structures , that is, the discourse, social practices in which it occurs and more ample structures. Theoretical assumptions were also used of Sistemico-Functional Linguistics(LSF), matching with categories of the Transitivity System of Halliday (1994, 2004), of the forms of representation of social actors in the socioeconomic perspective by Van Leeuwen (1997, 2008) and of the Appraisal system by Martin and White (2005). As we develop the argumentation on thesobre social role of religion in this thesis, we make use of the authors such as Freston (1994), Oro (1997, 2003), Campos (1996, 1999), Mariano (1999), Meneses (2008), among several ones. We have also used a series of concepts and categories coming from the field of communication and marketing on the business social responsability and social marketing . In this area, we take as references the contributions of Bueno (2003), Fossá and Sartoretto (2003) and Zenone (2006). The corpus of the work is framed by news taken at the newspaper Folha Universal, in which are given the social responsibility actions of the church . The timeframe used was on the editions of 2010 thru 2012. Results found at he analysis of the News lead to semantic features of Assessment of Affection, Judgment and Appreciation, many times followed by Gradation, and the Attribution, one of the subsystems of the Attachment, are evidence of positive assessments for the Universal Church and its agents and make up rethorical elements which provide structure for the discourse of the Universal Church at the newspaper Folha Universal consisted of its image (style) of social responsibility . Results show that the most frequente social actors of the discourse are, on one hand, the Universal Church itself and its volunteers, famous (actors, actresses, presenters), politicians and authorities, on the other hand, the population which was helped by the Church social projects . The first group seems to be Always activated, however the second one, most of the time rather passive. These are also represented by assimilation in most of the occurrences, however the other ones by individualization and nomination entitled by honorification, except for the volunteers that are represented either as an individual, or as a group

Elementos da ética sexual Tomista

This dissertation aims to present a elementar vision of thomistic thought about human sexuality from knowledges of vices and virtues. Introduce the notion of vice as otherwise to human nature and seek its etymological meaning, approaching with the neotestamentary perspective of sin and malice. This notion is based in aristotelian and augustinian notion, used by Thomas Aquinas. Also present two virtues inside of the christian thought about the sexuality. They are temperance and chastity. The temperance is a virtue that orders the pleasures of tact, and regulates the chastity. Finally, we show that is possible in thomistic thought admit the legitimacy of sexual pleasure and also the natural necessity in relations, and this relations just can be designed inside of legitimate marriage

Influência espaço-temporal e fisiológica na absorção de nutrientes e elementos tóxicos por Eichhornia crassipes visando o uso adequado da sua biomassa: o caso do Rio Apodi/Mossoró - RN

This study aims to determine the amount of nutrients and toxic elements in aquatic macrophytes of species Eichhornia crassipes present in River Apodi/Mossoró - RN and check some of the possibilities of using the biomass produced, based on the influence of space - temporal and physiological absorption of nutrients by plants. For this, was determined: Leaf area, Leaf wet mass, Leaf dry mass, Real humidity, Apparent humidity, Ash, Total nitrogen, Crude protein, Calcium, Magnesium, Potassium, Total phosphorus, Sodium, Iron, Copper, Manganese, Zinc, Nickel, Cobalt, Aluminum, Cadmium, Lead and Total chromium at different times, 2 sampling points and 2 parts of plants (leaves and roots). The results show that the levels of nutrients, protein and toxic elements present in plant tissue of Eichhornia crassipes are influenced by spatial, temporal and physiological variability. In general, because the maximum values in the dry matter for total nitrogen (4.4088 g/100g), crude protein (27.5549 g/100g), total phosphorus (0.642 g/100 g), calcium (1.444 g/100g), magnesium (0.732 g/100 g), potassium (7.51 g/100 g), copper (4.4279 mg/100g), manganese (322.668 mg/100g), sodium (1.39 g/100g), iron (194.169 mg/100g) and zinc (3.5836 mg/100g), there was the possibility of using biomass of Eichhornia crassipes for various purposes such as in food animal, products production for human consumption, organic fertilizers, fabrication of brick low cost, and crafts. For all these applications requires a control of the levels of substances in plant tissue. Based on the levels of nutrients and crude protein, the younger plants (0 Month) would be best to have their biomass used. Moreover, one factor that contributes to the use of larger plants (6 Months), the levels of toxic elements which have significantly small or below the detection limit. Therefore, further studies quantifying the biomass produced/m2 at 0 and 6 months are needed for a more correct choice for the best time of harvest

Avaliação da influência da matéria orgânica, na determinação quantitativa de metais em amostras de sedimento, por espectrometria de absorção atômica e análise de metais traços por fluorescência de raios-X

The proposal of this work is to evaluate the influence of the organic matter on the results of the analyses of the metals (Zn, Pb, Al, Cu, Cr, Fe, Cd e Ni) for Atomic Absorption Spectrometry (AAS), so much in the extraction stage as in the reading using for that the chemometrics. They were used for this study sample of bottom sediment collected in river Jundiaí in the vicinity of the city of Macaíba-RN, commercial humus and water of the station of treatment of sewer of UFRN. Through the analyses accomplished by EAA it was verified that the interference of the organic matter happens in the extraction stage and not in the reading. With relationship to the technique of X Ray Fluorescence Spectrometry (XRFS), the present work has as intended to evaluate the viability of this technique for quantitative analysis of trace metals (Cr, Ni, Cu, Zn, Rb, Sr and Pb) in having leached obtained starting from the extraction with acqua regia for an aqueous solution. The used samples constitute the fine fraction (<0.063 mm) of sediments of swamp of the river Jundiaí. The preparation of tablets pressed starting from the dry residue of those leached it allowed your analysis in the solid form. This preliminary study shows that, in the case of the digestion chemistry partially of the fine fractions of bottom sediments used for environmental studies, the technique of applied EFRX to the analysis of dry residues starting from having leached with acqua regia, compared her it analyzes of the leached with ICP-OES, it presents relative mistakes for Cu, Pb, Sr and Zn below 10%

Análise sobre diferentes abordagens de configuração eletrônica de elementos apresentados em livros de química

This study aimed to identify and review of the conceptual differences presented by authors of books, focusing on the theme of electronic configuration. It shows the changing concepts of electronic configuration, its implications for the cognitive development of students and their relations with the contemporary world. We identified possible obstacles in books generated in the search for simplifications, situations of different concepts of energy in the electron configuration for sublevels. For this analysis was carried out in several books, and some other general chemistry and inorganic chemistry without distinguishing between level of education, whether secondary or higher. It was found that some books for school books corroborated with higher education, others do not. To check the consistency of what was discussed, it was a survey of 30 teachers, it was found divergent points of responses, particularly with respect to the energy sublevels and authorship of the diagram which facilitated the electron configuration. It was found that the total 22professores, ie, 73,33% answered correctly on the energy sublevel more calcium (Ca) and 80%, ie, 24 teachers responded incorrectly on the iron. As for the authorship of the diagram used to facilitate the electronic configuration, we obtained 93, 33% of teachers indicated that they followed a diagram, and this was called "Diagram of Linus Pauling," teacher 01, 3,33%, indicated that the diagram was authored by Madelung and 01, 3,33%, did not respond to question. Was observed that it is necessary a more detailed assessment of ancient writings, as the search for simplifications and generalizations, not so plausible, lead to errors and consequences negative for understanding the properties of many substances. It was found that quantum mechanics combined with spectroscopic data should be part of a more thorough analysis, especially when it extends situations atoms monoelectronicpolieletrônicos to describe atoms, because factors such as effective nuclear charge and shielding factor must be taken into consideration, because interactions there is inside an atom, described by a set ofquantum numbers, sometimes not taken into account

Garantia literária: elementos para uma revisão crítica após um século

This study contributes to a critical synthesis of the principle of literary warrant, initially formulated by Hulme in 1911. Hulme proposed that the terms of a classification system should be derived from the literature to be classified, rather than based on purely theoretical considerations. Founding literary warrant on literature which is actually documented rather than on scientific or philosophical classifications or on the supposed authority of the first classificationists implied a clear departure from the conceptions of Harris and Dewey, who had used the classifications of Bacon and Leibniz as models. The validity of this principle over the past century is studied by means of diverse documental data (entries in dictionaries, retrieval by Google, etc.), as it is recognized as a main methodological element for classification standards and systems. This study also discusses the situation with respect to the top-down or bottom-up methodologies of system design. Three traditional applications of literary warrant are described as well as three new applications are suggested, in light of its methodological potential. It is possible to conclude that this principle will find increasing applications in other contexts, within and beyond Information Science.

Organização temática da doutrina jurídica: elementos metodológicos para uma proposta de extensão da classificação decimal de direito

Specificity and updating of the bibliographic classification systems can be considered a determinant factor to the quality of organization and representation of the legal documentation. In the specific case of Brazil, the Brazilian Law Decimal Classification, does not foresee specific subdivisions for Labor Law procedures. In this sense, it carries out a terminological work based on table of contents of doctrinal Labor Law books of the mentioned area, which are compared to the conceptual structure of the Brazilian Law Decimal Classification. As a result, it presents an extension proposal for Labor Procedures as well as a methodological background for further extensions and updates.

Programa de Avaliação de Desempenho: elementos constitutivos e pressupostos na prática avaliativa

This study analyzes the perceptions of technical and administrative UFPA, in relation to the insertion of the components and assumptions of DBP in evaluation practice. Addresses the history, concepts, meanings, about AD methods, skills, evaluation skills, the APF and AD UFPA and Programme itself. The research is characterized as a hypothetical-deductive, descriptive and applied, using the case study. Data were analyzed using a quantitative approach, using the descriptive and inferential statistics. Data were collected through the application of questionnaires to 222 technical and administrative searched IFES, not occupants of FG and CD. The results indicate that the factors perceived in relation to the constituent elements such as: evaluation practice, measurement of competence, program management, timing, individual skills and fundamentals of the program and those related to assumptions such as: democratic process, integrative perspective, character development and pedagogical continuous evaluation practices are perceived in the evaluation process. The study concludes that comparing the results of the constituent elements and assumptions of the PAD of thechnical-administrative UFPA, it can be said about a tendency to change, though subtle, compared to the traditional model of AD, directed only to the granting of career progression for a new logic based on the results, showing an early effectiveness of the program evaluation practice by law and by the Institution. The results are confirmatory of advance evaluation practice in the institution, more so than has previously been expected, which demonstrates the value of scientific criteria of scientific research
