This research aims to reconstruct the process of the recent expansion of the urban area of Mossoró (RN), particularly the dynamics of the Bela Vista neighborhood has been established as a new urban centrality. We start from the perspective that the process of urbanization as a result of the transformation of the capitalist system have profound impacts on the restructuring of urban space, which includes resetting and training of new urban centralities. The basic assumption accepts that recent economic changes have led to the adoption of new strategies for the location of large commercial equipment and services, contributing to urban expansion and redefinition of its centrality, leading to the formation of new urban centralities. The research strategy adopted consists of a case study oriented based on the analysis of qualitative information, but also incorporates quantitative information. Interviews with qualified informants were conducted, as well as field surveys, photographic documentation, in order to grasp the phenomenon observed. The survey results show that the Bela Vista neighborhood can be considered a new urban center, housing the specialized trade and service activities, as well as townhouses, which differentiates it from other areas of the city

In this work we presented an exhibition of the mathematical theory of orthogonal compact support wavelets in the context of multiresoluction analysis. These are particularly attractive wavelets because they lead to a stable and very efficient algorithm, that is Fast Transform Wavelet (FWT). One of our objectives is to develop efficient algorithms for calculating the coefficients wavelet (FWT) through the pyramid algorithm of Mallat and to discuss his connection with filters Banks. We also studied the concept of multiresoluction analysis, that is the context in that wavelets can be understood and built naturally, taking an important step in the change from the Mathematical universe (Continuous Domain) for the Universe of the representation (Discret Domain)

The Health Family Program (HFP) was founded in the 1990s with the objective of changing the health care model through a restructuring of primary care. Oral health was officially incorporated into HFP mainly through the efforts of dental professionals, and was seen as a way to break from oral health care models based on curative, technical biological and inequity methods. Despite the fast expansion of HFP oral health teams, it is essential to ask if changes are really occurring in the oral health model of municipalities. Therefore, the purpose of this study is to evaluate the incorporation of oral health teams into the Health Family Program by analyzing the factors that may interfere positively or negatively in the implementation of this strategy and consequently in the process of changing oral health care models in the National Health System in the state of Rio Grande do Norte, Brazil. This evaluation involves three dimensions: access, work organization and strategies of planning. For this purpose,19 municipalities, geographically distributed according to Regional Public Health Units (RPHU), were randomly selected. The data collection instruments used were: structured interview of supervisors and dentists, structured observation, documental research and data from national health data banks. It was possible to identify critical points that may be impeding the implementation of oral health into HFP, such as, low incomes, no legal employment contract, difficulty in referring patients for high-complexity procedures, in developing intersectoral actions and program strategies such as epidemiologic diagnosis and evaluation of the new actions. The majority of municipalities showed little or no improvement in oral health care after incorporating the new model into HFP. All of them had failures in most of the aspects mentioned above. Furthermore, these municipalities are similar in other areas, such as low educational levels in children from 7 to 14 years of age, high child mortality rates and wide social inequalities. On the other hand, the five municipalities that had improved oral health, according to the categories analyzed, offered better living conditions to the population, with higher life expectancy, low infant mortality rates, per capita income among the highest in the state as well as high Human Development Index (HDI) means. Therefore, it is possible to conclude that public policies that include aspects beyond the health sector are decisive for a real change in health care models

Guided by the social-historical perspective, this research aimed to understand how the adolescents in Assisted Freedom measure have meaning the family institution. The Pastoral Minor, located in the city of Natal, was chosen as space of investigation, whose social-educative program is the source of our concerns about the attendance of adolescents in conflict with law. The corpus was accomplished, mainly, through the individual semi- structured interview with four adolescents and seven of their relatives that participated of the research. We use another instruments to constitute the corpus, like the documental research of the technical reports on the participants of program files, and the registered notes in the field diary. As resource to data treatment, we use the Thematic Content Analysis. The data discussion was focused on the three thematic units that emerged: Family, Social-Educational Measure, Family and Social-Educational Measure. On the adolescents perspective, the family configures as a group based on the existence of affective bonds. Despite of the vulnerability of their familiar reality and their wish for freedom with their peers, the affective bonds revealed it as being important in their lives. This study, glimpse possibilities to contribute for the construction of public politics and attendance programs, that can be closer of the social-familiar reality of the adolescents who are in conflict with the law and, in this case, to promote their access to the statute of subjects of rights

Materials consisting of perovskite-type oxides (ABO3) have been developed in this work for applications in fuel cell cathodes of solid oxide type (SOFC). These ceramic materials are widely studied for this type of application because they have excellent electrical properties, conductivity and electrocatalytic. The oxides LaMnO3, LaFeO3, LaFe0.2Mn0.8O3 e La0.5Fe0.5MnO3 were synthesized by the method of microwave assisted combustion and after sintering at 800°C in order to obtain the desired phases. The powders were characterized by thermogravimetry (TG), X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM) and voltammetric analysis (cyclic voltammetry and polarization curves). The results obtained by XRF technique showed that the microwave synthesis method was effective in obtaining doping oxides with values near stoichiometric. In general, powders were obtained with particle size less than 0.5 μm, having a porous structure and uniform particle size distribution. The particles showed spherical form, irregular and crowded of varying sizes, according to the analysis of SEM. The behavior of the oxides opposite the thermal stability was monitored by thermogravimetric curves (TG), which showed low weight loss values for all samples, especially those of manganese had its structure. By means of Xray diffraction of the samples sintered at 800°C was possible to observe the formation of powders having high levels of crystallinity. Furthermore, undesirable phases such as La2O3 and MnOx were not identified in the diffractograms. These phases block the transport of oxygen ions in the electrode/electrolyte interface, affecting the electrochemical activity of the system. The voltammetric analysis of the electrocatalysts LF-800, LM-800, LF2M8-800 e L5F5M-800 revealed that these materials are excellent electrical conductors, because it increased the passage of electrical current of the working electrode significantly. Best performance for the oxygen reduction reaction was observed with iron-rich structures, considering that the materials obtained have characteristics suitable for use in fuel cell cathodes of solid oxide type

This work shows the results of the research: Attended Liberty Program Adolescents in Conflict with the Law and the Disapproval of Rights, effected in the community of Natal, Rio Grande do Norte, in period of august 2007 to September 2008. It aims to analyze the social-educative attendance directed to adolescents in conflict with the law through the state, since the Social-educative Measure Attended Liberty, known, as an idoneous way of confrontation to the practice of infraction acts imputed to the adolescent, that needs to give emphasis, in disadvantage of the Social-educative Measurement of Internment, to be proposed (ECA, art 118 and 199) to follow the adolescent in this quotidian, close to his family and community, proposing him through social-educative work, the access to education and occupancy, as well other public services, that help him to surpass the context of privation and disapproval of rights in which lives joined to his family. In our study, it was observed in sequence of approaching, subsidized for theoretical-methodological procedures justified in quantity and quality research, that were privileged to the documental research, the observation and the interview almost structured, besides a theoretical basis about the subject, that the relation of category and inequality in which the capitalist society sustains itself, does the practice of infraction acts imputed to the adolescent, acquires a classist character, in which the property of the money defines the access of the justice. And more, many of the poor adolescents that get into conflict with the law, dweller of the periphery districts of Natal/RN, becomes evident as for segment that has been attended in the Jurisdiction of the Infancy and Youth and in the LAN of Social-educative Attendance, becoming individual the infraction act and its confrontation. We hope in this work, to contribute for the care of the reality of the adolescent in conflict with the law in the Attended Liberty Program, without pretension to exhaust it, as well as later studies about the theme

A dissertação versa sobre a Política de Assistência Estudantil e o processo de luta pela democratização do acesso à universidade, no contexto de expansão do ensino superior em tempos de crise estrutural do capital. Apresenta como unidade de análise as particularidades da pós-graduação em Serviço Social da UFRN e tem como objetivo principal apreender e analisar as condições de permanência disponibilizadas pela UFRN aos discentes de pós-graduação no contexto de expansão do Ensino Superior. O percurso teórico-metodológico de análise adotado na pesquisa se fundamentou numa perspectiva crítica do objeto de estudo a partir de uma concepção de totalidade, que pressupõe apreender as determinações socioeconômicas e políticas que incidem sobre a política de ensino superior e as condições de vida dos discentes do Programa de Pós-Graduação em Serviço Social (PPGSS). As análises fundamentaram-se em pesquisa bibliográfica como base teórico-metodológica da investigação, articulada com as reflexões que resultaram dos dados empíricos da pesquisa de campo na perspectiva de apreensão do objeto, em sua densidade histórica e num quadro de múltiplas determinações. Do ponto de vista metodológico foram entrevistados 26 discentes e realizada análise documental referentes a leis e documentos da política educacional em nível federal e dos organismos internacionais. A luta por ampliação do acesso à universidade está na agenda dos movimentos sociais no âmbito da educação, no entanto na conjuntura dos governos de Luis Inácio Lula da Silva (2003 a 2010) e Dilma Rousseff (2011 a 2012) a tendência tem sido seguir as orientações dos organismos internacionais e promover expansão de vagas sem assegurar estratégias de permanência compatíveis com as exigências de excelência acadêmica postas, por exemplo, na pós-graduação. Discentes entrevistados acessam o ensino superior e os cursos de pós-graduação e vivenciam dificuldades diárias para atender com qualidade às exigências acadêmicas em face de suas condições materiais de vida e de trabalho e dos limites da política de assistência estudantil que tem um perfil de programas e ações localizadas

The Apodi river basin, particularly within the snippet that crosses Pau dos Ferros - RN city, place anthropogenic actions that interfere in the dynamic environment by modifying the local landscape. The reflection of these actions can be seen in the floods that occur in rainy periods (February to may) virtually every year in the city. It is important to stress that the project of integration of the waters of the San Francisco basin with the northern basin of Northeastern will perennial the main channel of the river basin, and generate greater impacts in the region. This work sought to define a methodology able to delimit areas susceptible to flooding in cities of semiarid Northeast based on the Pau dos Ferros RN city. The dissertation is divided into two chapters and introduction. The introduction presents a theoretical frame based on discussion of the concept of risk, their main characteristics and subdivisions; floods; geotecnologies; Apodi River basin; municipal data Pau dos Ferros RN and design integration of Francisco basin with the northern basins Northeast. The first chapter evaluates the urban expansion process between 1987 and 2008, delimiting the flood areas and analyzes the relationship between urban growth and retention areas. The second chapter identifies the flood risk areas in the Pau dos Ferros city. The methodology used was based on tools of geographic information system GIS from software SPRING/INPE 5.1, as well as bibliographical, satellite images, aerial photographs and field activities. The results obtained enabled view the rapid expansion of the urban area of Pau dos Ferros, which has doubled in a period of 22 years. The population density checks with greater intensity in South-central portion of the city, in flood areas and not flood (Cap. 01). It was noted also that some neighborhoods along the River Apodi are susceptible to more instances of flooding ranging from minimum to maximum, while in neighborhoods near the Riacho Cajazeiras floods occur to a lesser extent because of altimetry higher and lower water volume. (Cap. 02). It is expected that this work will help in the preparation of flood risk municipal map subsidising managers in implementing public policies targeted to the softening of urban flood-related issues in Pau dos Ferros RN and serve as a model for mapping of other cities with similar characteristics analyzed in this work

OBJETIVO: Avaliar o desempenho diagnóstico do índice de respiração rápida e superficial (IRRS) na predição do insucesso da extubação de pacientes adultos em terapia intensiva e verificar a adequação do valor de corte clássico para esse índice. MÉTODOS: Estudo prospectivo realizado na unidade de terapia intensiva de adultos do Hospital das Clínicas da Faculdade de Medicina de Botucatu, através da avaliação do IRRS em 73 pacientes consecutivos considerados clinicamente prontos para extubação. RESULTADOS: O IRRS com valor de corte clássico (105 ciclos/min/L) apresentou sensibilidade de 20% e especificidade de 95% (soma = 115%). A análise da curva receiver operator characteristic (ROC) demonstrou melhor valor de corte (76,5 ciclos/min/L), o qual forneceu sensibilidade de 66% e especificidade de 74% (soma = 140%), e a área sob a curva ROC para o IRRS foi de 0,78. CONCLUSÕES: O valor de corte clássico do IRRS se mostrou inadequado nesta casuística, prevendo apenas 20% dos pacientes com falha na extubação. A obtenção do novo valor de corte permitiu um acréscimo substancial de sensibilidade, com aceitável redução da especificidade. O valor da área sob a curva ROC indicou satisfatório poder discriminativo do índice, justificando a validação de sua aplicação.

Duas metodologias de expansão ao forno foram comparadas em 52 amostras de polvilho azedo de três Estados: Santa Catarina, Paraná e Minas Gerais. Os resultados obtidos permitiram visualizar uma proposta de classificação em nível nacional da expansão ao forno do polvilho azedo. No método instrumental foi usado o Farinógrafo Brabender para estabelecer uma massa de consistência padrão de 60UF e no método prático, a consistência semelhante da massa foi determinada de forma empírica. Com a metodologia instrumental obteve-se biscoitos com expansão superior à metodologia prática, mas maior coeficiente de variação, o que pode ser devido a maior sensibilidade do método. Ambas as metodologias poderão ter aplicação, dependendo da finalidade. A metodologia instrumental, pelo custo do equipamento, é mais adequada para laboratórios, desde que se utilize maior número de repetições, para reduzir o coeficiente de variação. Ambas as metodologias ensaiadas permitiram classificar as amostras com o mesmo perfil de desempenho. As amostras provenientes do Estado do Paraná apresentaram as maiores expansões ao forno quando comparados com os outros Estados. Pela metodologia prática a expansão média das amostras do Estado do Paraná foi de 14,1mL/g. As amostras do Estado de Minas Gerais apresentaram as menores expansões ao forno, em média de 13,3mL/g. Foi proposta neste artigo uma classificação para avaliar a qualidade do polvilho azedo, complementando a legislação brasileira que não estabelece este índice para o produto. Quanto à propriedade de expansão ao forno, as amostras avaliadas podem ser divididas em 3 tipos A, B e C. No tipo A (10%) amostras de polvilhos azedo são classificadas como qualidade extra, no tipo B (80%) os polvilhos são de média qualidade e o tipo C (10%) de qualidade inferior. Os resultados obtidos pela metodologia prática permitiram estabelecer como tipo A o polvilho azedo que apresenta um índice de expansão ao forno superior a 16,0mL/g, o tipo B o polvilho com índice de expansão entre 12,0mL/g a 16,0mL/g e o tipo C o polvilho com índice de expansão menor que 12,0mL/g.

Uma característica valorizada pelo setor alimentício é a propriedade de expansão dos grânulos de amido. Com este trabalho, teve-se por objetivo avaliar o efeito da concentração de ácido lático durante tratamento de modificação fotoquímica das féculas de batata-doce (Ipomoea batatas), biri (Canna edulis), mandioca (Manihot esculenta) e taioba (Xanthosoma sagittifolium). Pelos resultados obtidos neste experimento, nas condições em que este foi realizado, conclui-se que a concentração de ácido lático interferiu na propriedade de expansão das féculas de batata-doce, mandioca e taioba e não apresentou efeito na fécula de biri, devendo ser ajustado para cada tipo de fécula a ser modificada. Os índices de expansão obtidos nas diferentes féculas foram considerados baixos, quando comparados aos índices obtidos para fécula de mandioca modificada.
