Due to the occurrence of diseases in the use of structural reinforcements in composites, with presentation of concrete blanket detachment, has been identified the need to evaluate the performance of concrete reinforced with glass fiber. This study aims to evaluate these concretes by means of testing methodologies, using concrete with low resistance with structural reinforcement for confinement by preimpregnated glass fiber and traditional fiberglass blanket. The first stage of work was the development of methodologies for analysis, opting for four types, such as the acoustic survey, strength to compressive, the pull-off and ultrasound. Next, tests were carried out using the four selected methodologies in 30 of proof-of-specimens by 5x10 cm, 15 were reinforced with the traditional fiberglass blanket with 5specimens exposed to test a marine environment of marine coastline of Natal-RN and 15 were reinforced with a pre-impregnated glass fiber blanket, as well as 5specimens exposed to a test environment of the marine coastline of Natal-RN. After conducting the acoustic survey, it has been verified a lack of delaminating and air bubbles in the samples, confirming the absence of gross shortcomings in the implementation of the ribs both the traditional fiberglass blanket and in the preimpregnated fiber glass blanket. After carrying out methods of pull-off and compressive strengthening test it was observed that the reinforced proof-bodies with pre-impregnated glass blanket showed maximum stresses higher than the traditional fiberglass blanket; consequently a greater grip with the formation of a smaller area of . fracture, unlike traditional glass mat, which showed lower maximum stresses, with a greater area of fracture. It was also found that the traditional fiberglass blanket presented detachment of blanket-concrete interface, unlike the pre-impregnated fiberglass blanket, which showed a better grip on the blanket-concrete interface. In the trial of ultrasound there was no presence of cracks in the blanket-concrete interface, yielding to both blankets good compactness of the concrete. At the end of this work, they were developed and proposed two methods of testing for evaluation of reinforced concrete structures with composites, for standardization, the acoustic survey and pull-off

Structural changes in waste for zeolites synthesis are subject of many studies carried out in the synthesis of molecular sieves. These materials are named molecular sieves because they have well defined pore sizes and they have the capacity of select molecules by its size. In this work, it was studied the synthesis processes of two types of molecular sieves: pillared acid clays using as starting material one natural montmorillonite clay and the synthesis of zeolites from a silico-aluminous residue. This residue is a byproduct of the extraction of lithium -spodumene. The preparation of pillared acid clays was performed in two steps: 1° acid treatment of clay samples (time and temperature studies) and 2°pilarization of them with Al13 (Keggin ion). The temperature and acid concentration affect the removal of cations in the structure and porosity of the material obtained. The analysis of X-ray diffraction (XRD) and infrared spectroscopy (IR), showed that increasing the severity of the acid treatment compromises the structural material. Also the pore size distribution is approximately uniform. Despite presenting a structural disorganization, the samples were pillared. As evidenced by XRD increasing the basal spacing, specific area and uniform porosity by adsorption of N2. Regarding the microporous molecular sieves were synthesized zeolites A and NaP1 from a silico-aluminous residue, a byproduct of extracting lithium. The temperature and time of agitation during the synthesis were the most important factors for obtaining zeolite A. The aging of the gel and the highest crystallization time promoted the formation of zeolite NaP1 using a Si / Al ratio = 3.2

The 15Kh2MFA steel is a kind of Cr-Mo-V family steels and can be used in turbines for energy generation, pressure vessels, nuclear reactors or applications where the range of temperature that the material works is between 250 to 450°C. To improve the properties of these steels increasing the service temperature and the thermal stability is add a second particle phase. These particles can be oxides, carbides, nitrites or even solid solution of some chemical elements. On this way, this work aim to study the effect of addition of 3wt% of niobium carbide in the metallic matrix of 15Kh2MFA steel. Powder metallurgy was the route employed to produce this metallic matrix composite. Two different milling conditions were performed. Condition 1: milling of pure 15Kh2MFA steel and condition 2: milling of 15Kh2MFA steel with addition of niobium carbide. A high energy milling was carried out during 5 hours. Then, these two powders were sintered in a vacuum furnace (10-4torr) at 1150 and 1250°C during 60 minutes. After sintering the samples were normalized at 950°C per 3 minutes followed by air cooling to obtain a desired microstructure. Results show that the addition of niobium carbide helps to mill faster the particles during the milling when compared with that steel without carbide. At the sintering, the niobium carbide helps to sinter increasing the density of the samples reaching a maximum density of 7.86g/cm³, better than the melted steel as received that was 7,81g/cm³. In spite this good densification, after normalizing, the niobium carbide don t contributed to increase the microhardness. The best microhardness obtained to the steel with niobium carbide was 156HV and to pure 15Kh2MFA steel was 212HV. It happened due when the niobium carbide is added to the steel a pearlitic structure was formed, and the steel without niobium carbide submitted to the same conditions reached a bainitic structure

This dissertation establishes a viewpoint in the Social Cience Field of the Nymphs image in the romanesque construction of the twentieth century based in modern archaeology. Our literary corpus is constitututed by the book of the russian author callled Wladimir Nabokov entlited Lolita and the book Presença de Anita, from a brazilian author called Mario Donato. Both works had a singular repercussion involving an erotic conception wich was faced as pornographic and baffling. We appeal to Georges Bataille‟s and Foucault‟s discussion in order to observe it through an erotic viewpoint from an inner experience not submitted to normalizations. Such experiences provoke a feeling of something unknown and it reflects wild singularities proposed by Foucault and related with many misunderstanding things presented in institutions and cultures. Furthemore Bataille‟s conception about erotism will give us conditions to analyze nymphs‟ bodies in order to see themselves from their main characteristics, such as seduction and tempting and maligning forces. We still aim to focus the paradigm of mankind and nature in the direction presented by Edgar Morin. He analyzes some feelings that nymphs provoke and their relation between men and death. In adittion, we present in this issue some questions between culture and biology, focusing on the initial period of larva (wich means the beggining), bringing up what is ready to be born, a mythical and significant body shown in the media. Lolita in the cinema and A Presença de Anita in the TV was disturbing in society and it projected the possibility of a syntaxes of desire. It can has a symbolic purpose or it can be a kind of social and cultural phenomenon, wich is an object of representation. Our purpose is to immersion/emerge in the Nimphs‟s body with adventure and its risks at the same time in wich we are crossing frontiers

This work basically achieve three goals. Critically investigate the liberal democratic regime and its historical reformulation, rejecting the popular power and popular self-organization, limiting the entry of normal citizen in decision-making, believing in the market as a mediating body in regulating of the different life spheres of social. Starting from the critical liberal democracy, it discussed the concept of popular participation in the democracy, searching new democratically horizons, where the masses could have the opportunity to make decisions about their own destiny. On the basis of theoretical discussion on participation, we discuss a concrete instrument of participation, the Participatory Budgeting, comparing two participatory experiences in North and South

The current study presents an analysis about the automation of the lawsuits in Brazil, which opens a new direction to be followed by the National Secretary of Justice, applied indistinctively to the civil, criminal and labor lawsuits, as well as to the special court houses at any degree of juridisdiction. It treats, specifically, about the transition from the classic lawsuit with bureaucratic aspects to the electronic one, based on the simplicity of the functions, the quality of the oral and the readiness. The light of the constitutional principle of the reasonable duration of the lawsuit, while fundamental rigth of the defendant and, under de protection of the democratic guarantee, it investigates, from the theory of the fundamental rights to the reform movement of the lawsiut, in the scenery of the alien law and national law, the latter, mostly because it has the automation as a necessary improvement claimed by modernity, yet without forgetting of the humane character inherent to the criminal lawsuit. It faces the issue of of the disruption of the paradigm of the written formality of the Brazilian lawsuit, the problem of the resistance to the new automized method, the use of the video conference for the inquest of the witnesses as well as for the questioning of the defendant, the advancements of the virtual lawsuit on the Superior Courts, Federal Supreme Court and Superior Court of Justice, it treats also about the role of the National Council of Justice - CNJ - to uniformize the legal proceedings in the country. Without neglecting the effective respect to the fundamental rights, it focuses the cultural change necessary so that the electronic technology can be, in fact, in the indictment system, the means to reach with excellency the citizenship by the simplification of the legal proceedings, transposing the baseless bureaucracy and assuring an effective judicial service assistance in order to have a better quality of life

This research work deals with the compilation of a dictionary on clothing terminology intended to be used as a pedagogic tool as part of the teaching and learning process in the Textile Engineering Course at the Federal University of Rio Grande do Norte. The main terms were selected and assessed by a team of textile teachers and students with the objective to be structured as a conceptual body of information on the following sub-areas of clothing terminology: materials (fabrics and trimmings) and products (garments). This research comprises three main steps: (a) characterization and understanding of the technical vocabulary in the clothing area as well as the identification of a pedagogic demand for a dictionary on clothing terminology, clearly expressed by the textile lecturers and students involved in the assessment of the need and validation of this project development; (b) a proposal for a specific methodology for the compilation of the dictionary which could help the communication process in the lecturing of clothing terminology and (c) based on the terminological principles and the technique of focal groups the dictionary was assessed. The technique of focal groups was used in the first step. In the second step the technique used was that of the terminological methodology adapted to the teaching approach in the Textile Course. In the third step the technique of focal groups was again utilized. It was observed that the main concern of lecturers and students is the lack of a standardized vocabulary, which renders difficult the communication process in both the teaching and learning activities as well as the professional ones in the textile industries. Various aspects, which can overlap, cause this lack of standardization. The main ones pointed out by the study team in the focal groups are: usage of regional words or expressions, usage of foreign words or expressions, analogies, and the low level of formal education, mainly among the industry workers. Another aspect to be considered is the lack of textile literature written in the Portuguese language of Brazil. This evidence shows the importance of a clothing terminology dictionary which will benefit both the education and professional activties in this field of knowledge. This dictionary will also give a substantial contribution to terminological standardization in our research field. With view to fulfill this demand, a dictionary of clothing terminology was compiled with 760 main entries, according to the modern practice in terminology with the necessary modifications concerning our needs. The result of the dictionary assessment was very assertive regarding its structure, contents and possible use in various contexts. The team work emphasized their contribution to the standardization process of the terms that proved to be one of the most important and difficult aspects of this researh work. The significance of this structured terminological dictionary was confirmed by the focal group participants relating to its use for teaching and learning activities, as a reference book, as a source of technical information and also as a tool for pedagogic studies and planning, as well as a significant collaboration to the pedagogic practices in the textile engineering course at University or any other educational institution. Besides, this dictionary can also be used to supply information within the textile field. We are aware that the present work will not exhaust the objectives of this research due to its limitations in opposition to the vast complexity demanded by the compilation of a complete work including all the areas and sub-areas of textile engineering. However, it is an important source for dissemination of concepts on the field of clothing terminology and a tool to effective standardization of the terms used in this subject field

O número de instituições de ensino superior no Brasil vem crescendo bastante nos últimos anos. Com isso a preocupação com a qualidade dos cursos ofertados também tem aumentado. Para avaliar essa qualidade do ensino o governo instituiu formas de avaliação e vem aperfeiçoando a cada ano. As instituições, por sua vez, buscam bons resultados nessas avaliações a fim de utilizar como item de vantagem competitiva, uma vez que as notas obtidas por elas chamam atenção de novos clientes. Dessa forma, o presente trabalho buscou analisar as principais estratégias acadêmicas utilizadas na avaliação de desempenho dos cursos de Ciências Contábeis, da região de Natal-RN, no ENADE. Trata-se de uma pesquisa de abordagem qualitativa e quantitativa, e foi aplicado um estudo de caso complementado por um survey. A parte qualitativa foi obtida através de entrevistas semiestruturadas realizadas com os coordenadores dos cursos e a quantitativa foi obtida através da aplicação de um questionário fechado aos alunos aptos a participarem do ENADE no ano de 2012. Foram estudadas todas as instituições em Natal que possuem o curso de Ciências Contábeis, modelo presencial, sendo ao todo 10 (dez) instituições identificadas. Os dados foram analisados por meio da análise de conteúdo (entrevistas) e do software SPSS® 18 (survey). Foram utilizados os métodos de análise fatorial, através da análise de componentes principais, com rotação Varimax e normalização Kaiser. Em relação à análise da importância do ENADE sob a perspectiva dos estudantes, foi utilizado o teste não paramétrico de Mann-Whitney. Como resultados da pesquisa, foi identificado que tanto os discentes como os coordenadores de curso entendem a importância do ENADE, também observou-se que a satisfação dos discentes com a instituição refletiu nos resultados obtidos por esta, bem como, o momento em que foi iniciada a preparação para o exame também refletiu nas notas recebidas pelas instituições

O procedimento de uniformização e elevação do teor de água das sementes é recomendável para se obter resultados uniformes e confiáveis, em testes para a qualidade fisiológica de sementes, como o envelhecimento acelerado e a deterioração controlada. O trabalho teve como objetivo avaliar a qualidade fisiológica de sementes de milho, após a hidratação sob diferentes métodos e temperaturas, visando à elevação do teor de água para 15; 20 e 25%. Empregou-se o delineamento inteiramente casualizado, em esquema fatorial 4 x 2, com quatro repetições. Os tratamentos foram constituídos de quatro métodos de hidratação (substrato úmido, atmosfera úmida, imersão em água e adição da quantidade de água requerida) sob duas temperaturas (20 e 30 °C). Após a hidratação, as sementes foram submetidas às seguintes determinações: teor de água, condutividade elétrica, porcentagens de germinação e de plântulas normais na primeira contagem do teste de germinação, massas secas das porções aérea, radicular e total das plântulas obtidas na primeira contagem. O método da atmosfera úmida proporciona redução da qualidade fisiológica das sementes de milho nos três teores de água. A temperatura de 30 °C e o método da imersão direta em água não alteram a qualidade fisiológica das sementes de milho, mostrando-se adequados para a hidratação visando à elevação do teor de água para 15; 20 e 25%.

Um experimento foi conduzido no NuPAM/FCA/UNESP, Botucatu-SP, objetivando avaliar a dinâmica de retenção de água e o caminhamento de um traçante (simulando um herbicida) em diferentes coberturas mortas. Os tratamentos foram constituídos pelo monitoramento do traçante FD&C-1 pulverizado sobre coberturas mortas de cevada, trigo, aveia-preta colhida, aveia-preta rolada, azevém, milheto e capim-braquiária, nas quantidades de 3.000, 6.000 e 9.000 kg ha-1, antes e após simulação de chuvas. As repetições constituíram-se de oito conjuntos de PVC + funil + béquer com palha, onde, através da chuva lixiviada pelas palhadas e do peso dos suportes de PVC, foram estimadas a retenção e transposição da água, assim como quantificado o traçante extraído, através de procedimentos espectrofotométricos. Os diferentes tipos de resíduos culturais mostraram-se similares quanto à retenção da água da chuva, ocorrendo uniformização entre os primeiros 7,5 e 15 mm de precipitação. A formação de pontos secos associados a canais preferenciais de escorrimento induziu menor capacidade de embebição e retenção da água das chuvas pelas palhadas. As máximas capacidades médias de retenção da chuva pelas coberturas foram de 1,22, 1,99 e 2,59 mm para 3.000, 6.000 e 9.000 kg de matéria seca ha-1, respectivamente. As precipitações iniciais entre 10 e 20 mm foram fundamentais para o molhamento uniforme das palhadas e carregamento do traçante até o solo, independentemente do tipo e da quantidade de palha. Esse comportamento indica ser viável a utilização de programas similares de controle de plantas daninhas para diferentes tipos e quantidades de palha em sistemas de plantio direto.

Objetivou-se com este trabalho avaliar a eficiência de pontas de pulverização com diferentes vazões e tamanhos de gotas na deposição e na dessecação de plantas de Brachiaria brizantha cv. Marandu, além da quantificação das perdas da calda de pulverização para o solo. O delineamento experimental adotado foi o de blocos casualizados, com quatro repetições. Cada unidade experimental constituiu-se de três linhas de 5 m de comprimento, espaçadas de 1 m. A aplicação dos tratamentos foi realizada 16 meses após a semeadura da braquiária; 40 dias antes da aplicação foi realizada uma roçagem para uniformização da área. Foram avaliadas as pontas de pulverização de jato plano XR 11001 VS (100 L ha-1) e XR 11002 VS (200 L ha-1), jato cônico TX-4VS (100 L ha-1) e TX-8 VK (200 L ha-1), ponta com indução de ar AI 11002 VS (200 L ha-1) e jato plano duplo TJ60 11002 VS (200 L ha-1). A calda foi aplicada com o herbicida glyphosate na dose de 1.800 g ha-1, mais um traçador (FD&C nº1 2.000 ppm). Foram coletados imediatamente após a aplicação da calda 25 perfilhos por repetição, sendo lavadas separadamente as folhas e caules de cada perfilho em 150 ml de água destilada, para posterior quantificação do traçador em espectrofotômetro. Os dados foram ajustados à curva de regressão pelo modelo de Gompertz. Todas as pontas utilizadas foram eficientes na dessecação das plantas de B. brizantha, independentemente do volume utilizado, o que evidencia a possibilidade de redução do volume de aplicação e da dosagem do herbicida na dessecação de pastagens, considerando-se a utilização de herbicidas sistêmicos. Ressalta-se que houve diferença na quantidade e na uniformidade de distribuição da calda pulverizada nos alvos avaliados em função da ponta testada e, conseqüentemente, do volume utilizado.

O artigo trabalha a noção de amizade em Foucault como um modo de vida que se opõe ao processo de normalização empreendido pelo biopoder. Inicia com uma caracterização acerca do Estado Moderno. Logo após, aborda a historicidade dos processos de subjetivação e de como a atitude frente a estes implica estados de maior autonomia ou sujeição. em seguida, aborda a amizade como resistência à normalização, situando-a em relação ao prazer e à sexualidade. Por fim, discute o papel da filosofia no processo de constituição da amizade, particularmente quanto à possibilidade de pensá-la por meio de uma teoria das relações.

Buscou-se cartografar as instituições de assistência social que atendem à infância e à adolescência consideradas em situação de risco pessoal e social, em um município do interior do estado de São Paulo, utilizando o instrumental da análise institucional. O papel de membro do Conselho Municipal dos Direitos da Criança e do Adolescente e do Conselho Municipal de Assistência Social facultou a realização de uma análise documental nos arquivos desses Conselhos, relativa às entidades assistenciais cadastradas, tais como organizações governamentais, organizações não-governamentais e outros estabelecimentos filantrópicos. Os resultados indicam que, no universo da Assistência Social, a constelação criança/adolescente orbita em torno do astro-rei socioeducativo. Todas as atividades desenvolvidas nas entidades parecem recobertas por esse significantemestre, que conota dimensões pedagógicas e terapêuticas, educativas e corretivas, de vigilância e de prevenção, promovendo controle e normalização.
