Estudo das propriedades críticas do processo epidêmico por par com difusão de pares

The pair contact process - PCP is a nonequilibrium stochastic model which, like the basic contact process - CP, exhibits a phase transition to an absorbing state. While the absorbing state CP corresponds to a unique configuration (empty lattice), the PCP process infinitely many. Numerical and theoretical studies, nevertheless, indicate that the PCP belongs to the same universality class as the CP (direct percolation class), but with anomalies in the critical spreading dynamics. An infinite number of absorbing configurations arise in the PCP because all process (creation and annihilation) require a nearest-neighbor pair of particles. The diffusive pair contact process - PCPD) was proposed by Grassberger in 1982. But the interest in the problem follows its rediscovery by the Langevin description. On the basis of numerical results and renormalization group arguments, Carlon, Henkel and Schollwöck (2001), suggested that certain critical exponents in the PCPD had values similar to those of the party-conserving - PC class. On the other hand, Hinrichsen (2001), reported simulation results inconsistent with the PC class, and proposed that the PCPD belongs to a new universality class. The controversy regarding the universality of the PCPD remains unresolved. In the PCPD, a nearest-neighbor pair of particles is necessary for the process of creation and annihilation, but the particles to diffuse individually. In this work we study the PCPD with diffusion of pair, in which isolated particles cannot move; a nearest-neighbor pair diffuses as a unit. Using quasistationary simulation, we determined with good precision the critical point and critical exponents for three values of the diffusive probability: D=0.5 and D=0.1. For D=0.5: PC=0.89007(3), β/v=0.252(9), z=1.573(1), =1.10(2), m=1.1758(24). For D=0.1: PC=0.9172(1), β/v=0.252(9), z=1.579(11), =1.11(4), m=1.173(4)

Repercussão geral e súmula vinculante: os efeitos no controle difuso

Brazil since its first republican constitution has adopted systems of laws control. The review activity was given to three state powers or functions state, Executive, Legislative and Judiciary. However, it appears that in the country along the constitutional history, has stood considerably the jurisdictional control of the most important control. Initially, back in 1891, Brazil adopted the jurisdictional control of diffuse from U.S, whose role in monitoring of standards is delivered to all organs of the judiciary, which may face a case, put on trial, ascertain whether or not the possibility of applying a law, removing its impact in case of unconstitutionality. In 1969, entered in the second legal model of judicial review, the concentrated control of constitutionality, whose inspiration comes from the positivist theory of Hans Kelsen, and was adopted by the Austrian Constitution of 1920. According to the abstract control the supervision of law is given to a Court or Constitutional Court, responsible for the analysis of the legal constitutionality independent of its application to a specific case. In Brazil the role of concentrated control was handed over exclusively to the Supreme Court, which serves as the Constitutional Court, which accumulates that function with other constitutionally provided jurisdiction. Throughout this period, from 1891 until today, Brazil has maintained a dual system of judicial control of legal constitutionality, where they coexist and harmonize the diffuse control exercised by any organ of the Judiciary, and concentrated control of competence the Supreme Court. However, one must recognize that with the advent of the Federal Constitution of 1988, the concentrated control has emerged on the national stage due to two important factors: the expansion of the legal capacity to sue and the inclusion of other ways control, besides the already known Direct Claim of Unconstitutionality. This concentrated control and projection of the Supreme Court s attempt to become a true constitutional court, led to a relative weakening of diffuse control even when performed by the Brazilian Constitutional Court. In order to become a true constitutional court, all decisions handed down by the Supreme in the exercise of constitutional jurisdiction should have the same weight and the same measure, or at least bring improvement to similar effects, once is the responsible for the final word when it comes to constitutional interpretation. Thus, the writs of certiorari and stare decisis were responsible for profound changes in the diffuse control, allowing the Supreme Court can strengthen its decisions even in the diffuse control. These two institutions have substantially changed the legal status of diffuse control, allowing an extension of the effects of decisions handed down by the Supreme Court, so that you can no longer be said that the effects of this control to restrict the disputing parties in the process

Televisão universitária do RN (TVU): contribuição para a democratização da informação e a difusão do conhecimento científico produzido pela universidade

In this thesis we propose to investigate the contribution that the Universitary Television from Rio Grande do Norte state, Brazil (TVU RN), offers to democratization of information and diffusion of the scientific knowledge produced by the Federal University of Rio Grande do Norte (UFRN) from the perception of their own students. We adopt the basic assumption in wich the TVU RN needs to be connected with the scope of the current UFRN policy, since plays an important role regarding democratization and social inclusion policies in UFRN. We support the thesis that TVU UFRN offers important information for those who are part of academic culture (COULON, 1995a; 1995b, CHARLOT, 2000; BOURDIEU, 2007, 2005, 1997, 1996, 1975), as well as for society in wich it is inserted, since it contributes to the dissemination of scientific knowledge and relevant information about the university. We consider TVU RN a Public Sphere (HABERMAS, 2002; 2003a, 2003b; 2003c; 1999; 1989) conducive to discussion of issues involving higher education. Researches on Universitary Television are recent and some studies on it advanced in the way to define it and present it as a means of dissemination of scientific knowledge (ROCHA, 2006; COUTINHO, 2006; CALLIGARO, 2007; AIRES, 1999; PORCELLO, 2002; PRIOLLI, 2003, 2008, 2009; MAGALHÃES, 2002, 2008; RAMALHO, 2008; 2010; CARVALHO, 2006). For our investigation we chose the combination of quantitative and qualitative methods, both equally valid and accepted by many authors (FLICK, 2009; BAUER; GASKELL, 2002; RICHARDSON, 1999; LAVILLE; DIONNE, 1999). We developed a questionnaire initially with objective questions ending up with open questions of free text. The questionnaire was developed and hosted from a tool of Google Docs and the link to the webpage containing those questionnaires was sent by e-mail by the Permanent Commission of Vestibular of UFRN, COMPERVE, for all university students who were with their registration (status) active in the COMPERVE registers of the second half of 2010. The analysis of this material was performed using the techniques of content analysis and, within this mode was chosen thematic analysis considered appropriate for both qualitative and quantitative research (BARDIN, 2004; MINAYO, 2002). The investigation found that although most students consider that the TVU RN contributes to the democratization of information and dissemination of scientific knowledge produced in university, and moreover to arouse the interest of the academic community, still has not yet become an object of interest of the entire academy. Therefore, the research highlights the relevance and abrangency of further studies on the TVU RN due to the strategic role it plays in this new reality of public universities in the country. In addition, we suggest to the UFRN managers that they put TVU within the hall of discussions in order to receive the so much needed investment for any university organ

Processo de difusão com agregação e reorganização espontânea em uma rede 2D

Difusive processes are extremely common in Nature. Many complex systems, such as microbial colonies, colloidal aggregates, difusion of fluids, and migration of populations, involve a large number of similar units that form fractal structures. A new model of difusive agregation was proposed recently by Filoche and Sapoval [68]. Based on their work, we develop a model called Difusion with Aggregation and Spontaneous Reorganization . This model consists of a set of particles with excluded volume interactions, which perform random walks on a square lattice. Initially, the lattice is occupied with a density p = N/L2 of particles occupying distinct, randomly chosen positions. One of the particles is selected at random as the active particle. This particle executes a random walk until it visits a site occupied by another particle, j. When this happens, the active particle is rejected back to its previous position (neighboring particle j), and a new active particle is selected at random from the set of N particles. Following an initial transient, the system attains a stationary regime. In this work we study the stationary regime, focusing on scaling properties of the particle distribution, as characterized by the pair correlation function ø(r). The latter is calculated by averaging over a long sequence of configurations generated in the stationary regime, using systems of size 50, 75, 100, 150, . . . , 700. The pair correlation function exhibits distinct behaviors in three diferent density ranges, which we term subcritical, critical, and supercritical. We show that in the subcritical regime, the particle distribution is characterized by a fractal dimension. We also analyze the decay of temporal correlations

Atividade antibacteriana e cicatrizante do óleo de buriti Mauritia flexuosa L

O objetivo deste estudo foi avaliar a atividade antibacteriana in vitro e cicatrizante do óleo de buriti (M. flexuosa) em feridas realizadas em ratos (Rattus norvegicus albinus). Para a avaliação antibacteriana in vitro, foram utilizados cinco patógenos bacterianos incluindo espécies gram-positivas e espécies gram-negativas mediante o uso do método de difusão em ágar. Para a avaliação da atividade cicatrizante, foram utilizados 40 ratos da linhagem Wistar, divididos em dois grupos: o grupo I, composto por 20 ratos com feridas cutâneas, tratados com aplicação tópica do creme base com 10% de óleo de buriti, e o grupo II, controle, com o mesmo número de animais que receberam a aplicação tópica do creme base. A aplicação do produto foi realizada em feridas padronizadas, circulares de 1cm de diâmetro na região dorsolombar. As avaliações clínica, morfométrica e histopatológica das feridas foram realizadas no 3°, 7°, 14° e 21° dias. Em relação à avaliação da atividade antibacteriana, os resultados mostraram que houve inibição do crescimento bacteriano em quatro dos cinco patógenos testados. Em relação à área da ferida, foi observada redução significativa da área no 14o dia e maior percentual de contração das feridas do grupo tratado em relação ao controle. No décimo quarto dia, as feridas tratadas com o óleo do buriti apresentavam aumento significativo na contagem de fibroblastos e fibras colágenas, além de completo processo de reepitelização, enquanto o grupo controle necessitava de mais tempo para resolução do processo cicatricial

Desenvolvimento de coleções de fontes de informação eletrônica em bibliotecas universárias

O contexto hodierno caracteriza-se como um panorama de uso contínuo de informação nas mais variadas esferas da sociedade. A informação é usada em diversos contextos sob vários formatos e isso se torna possível com a evolução tecnológica realizada em ritmo acelerado, sobretudo nos últimos dois séculos. Essa evolução trouxe consigo a possibilidade ampliada de acesso à informação, mas por outro lado, impôs desafios circunstanciais no seu tratamento e difusão. Nos diversos tipos de unidades de informação, faz-se necessária a adoção de estratégias para a melhoria do gerenciamento e desenvolvimento das coleções, sobretudo as coleções digitais. De tal modo, o trabalho visa a traçar um panorama ligado às questões relacionadas à comunicação cientifica com a bibliotecas universitárias, com vistas a ampliar o debate sobre o desenvolvimento digital de coleções de periódicos em bibliotecas universitárias, bem como aspectos relacionados à adoção de critérios de seleção e avaliação destes itens de informação. Aborda os casos específicos, como o do Portal Capes e o SciELO como coleções digitais de periódicos sujeitos a estratégias de desenvolvimento das coleções. Aponta opções para a melhoria da gestão da coleção digital em bibliotecas universitárias. A metodologia empregada foi a de pesquisa bibliográfica em uso de fontes eletrônicas e convencionais, bem como análise de critérios utilizados na Avaliação e Coleções para Bibliotecas Universitárias e o Indicadores Qualis pela Condenação de Aperfeiçoamento de Pessoa de Ensino Superior (CAPES).

Gestão híbrida em cooperativa de crédito: uma análise a partir do interesse, participação, satisfação e expectativa dos cooperados da COOPERUFPA

The globalization of markets has confirmed for the processes of change in organizations both in structure and in management. This dynamic was also observed in credit unions because they are financial institutions and are under the rules of the Brazil´s Financial System. Given the context of organizational changes in the financial capital has played the traditional management reform is urgent. In organizations credit unions, given its dual purpose, because in the same organizational environment and capitalism coexist cooperative whose logics are antagonistic, but can live through the balance between instrumental rationality and substantive rationality in credit unions. Based on this concept a new form of management should be thought to be able to accommodate the demand of cooperative, community, government and the market. Hybridization has been observed in management practices` COOPERUFPA into dimensions financial, social and solidarity participation with a trend in paradigmatic form of hybrid management, in that it directly or indirectly affect the management decisions in the credit union. The hybrid management is a trend that has been setting the basis for societal transformation, so that credit unions promote actions of welfare oriented cooperative members and the community around the same time that attend the dynamics of market globalization. These actions, in the context of hybrid management should be implemented by COOPERUFPA from the sociability of the remains and the wide diffusion of solidarity culture between cooperative partnership as a way to recover their participation in trade relations, financial and the social collective developement. For the members of COOPERUFPA financial interest is evidenced in greater relevance for the social interest given its dominant relationship as "mere customer" of the credit union, however, the proactive participation of the life of the cooperative credit union is one of its expectative among of participation of to share power in decisions by general meetings. This passivity`s cooperator of the COOPERUFPA in defending the ideals overshadowed the spread of cooperative principles and values of cooperation among them. Thus his conception for COOPERUFPA in the financial dimension, social and solidarity democracy, performed transversely. The COOPERUFPA for not developing an education policy for the cooperation among its members, contributed to a process of collective alienation of cooperative ideals, since the cooperative do not understand the reality that surrounds them as members of an organization whose mission is to social and financial sustainability of its members

Comunicação pública e marketing político na gestão pública municipal

Based on the definitions of Public Communication, Political Marketing, Public Interest Information and Communication as a Tool of Governance, the study notes the use of the news section of the websites of the City Christmas and Mossoro, Rio Grande do Norte, in regard to strengthening citizenship and encouraging participatory management, from the characterization of materials like pieces of Political Marketing and Public Communication. Data collection in qualitative research was conducted from August to September 2011 and content analysis showed that the appropriation of public property for personal use is a reality, despite legal requirements to the detriment of strategic communication and governance for results from the dissemination of information of public interest and the establishment of a communication channel between State Government and Society. Elements of this study suggest the need for further research to deepen the discussion

Bibliotecas digitais em Arquitetura e urbanismo: um estudo sobre a arquitetura da informação digital

The goal of this paper was to search the state of the art from the Digital Libraries in Architecture and Urbanism in the Higher Education Institutions (IES) through conceptualizations and showing the importance of Digital Libraries in the disclosure and easing of information transferring. Questions about digital information architecture, usability, digital preservation and accessibility were approached. The research was made in the websites of Brazilian Universities, firstly to identify the institutions which offered the Architecture and Urbanism course, focusing on postgraduate education. After identifying the offering, the research was done by analyzing the contents, storage and dissemination and access to information, these libraries. It was found that the digital libraries are increasingly and taking part of organizations and educational institutions focusing on the knowledge dissemination releasing digitally information that may be needed for institution or the individual. A monitoring was done over of the physical and computational restructuring of the Board of Studies and Research in Architecture and Urbanism (Câmara de Estudos e Pesquisa em Arquitetura e Urbanismo, CEPAU), from the Architecture and Urbanism Course of the Federal University of Rio Grande do Norte (UFRN), showing the need of installing a Digital Library to integrate the databases of PPGAU s research groups, which today remain independent, with no interface among themselves. The research chosen area was Architecture and Urbanism, because there is a gap and little documentation about digital libraries in this area

Comunidades tradicionais em áreas protegidas: convergências e lacunas da Política Urbana e Ambiental na Reserva de Desenvolvimento Sustentável Estadual Ponta do Tubarão/RN

This work presents a reflection on possibilities and boundaries of consolidation and expansion of human settlements characterized as traditional communities that are located within protected areas, using as study reference the State Sustainable Development Reserve Ponta do Tubarão, at Rio Grande do Norte state. The main topics highlight the conflict between the right to housing and the prevalence of fundamental rights of traditional populations, opposed to the diffuse right to environment, according to the regulatory framework of the Brazilian Urban and Environmental Policies. At the same time that these settlements, historically built, are substantiated by the principles of recognition of rights to traditional populations, they are in a condition of complexity to the resolution of conflicts in its urban dimension and lead to an impairment of natural sites. This work questions how the instruments of land use and occupation are defined and relate to environmental planning, especially considering that the settlements are located in Permanent Preservation Areas (APP). It aims to further the discussion of the urban dimension in settlements, characterizing its formation and growth process, to identify the gaps and convergences between the Urban and Environmental Policy, under the foundations of a socio-environmental approach. The results spotlights the conflicts between occupation and natural areas, inferring that the definition of Urban Policies instruments and its integration with Environmental Policies instruments account for essential and priority actions to the achievement to the rights to a sustainable city, as determined in the Cities Statute and environmental protection goals, defined for the Conservation Units
