O propósito deste estudo foi o de contribuirmos para uma reflexão que abordasse o Golfe como um dos pólos de desenvolvimento da Região Autónoma da Madeira. Começamos por fazer um enquadramento do problema, caracterizando e analisando algumas relações entre a legislação de suporte, a política desportiva regional, as características e potencialidades do Golfe, em geral, e mais especificamente do Swing, através da bibliografia que acerca dos mesmos é produzida, nos seus mais variados contextos e níveis de análise. Apresentamos uma conjectura alicerçada na Sistemática das Actividades Desportivas, mais concretamente, através do Modelo dos Desportos Individuais de Almada et al (2008), onde, identificamos os diferentes tipos de capitais susceptíveis de serem rentabilizados através do Golfe, nomeadamente os capitais Turismo, Saúde e Educação, de modo a que a modalidade se possa constituir como um pólo de desenvolvimento regional. Como forma de refutação da conjectura efectuada analisamos a título exploratório a viabilidade de algumas situações aplicativas ao nível dos capitais identificados. Foi possível concluir que o Golfe pode assumir-se como um pólo de desenvolvimento da Região Autónoma da Madeira caso se considerem, de forma articulada, os diferentes tipos de capital em jogo, pois os mesmos podem ser relevantes no desenvolvimento de uma região ou país.

The managing Conselho of public politics constitute one of the main experiences of democracy in Brazil contemporary representing a conquest for construction of a democratic institutionalism. The historical newness consists of the intensification and the institutionalization of the dialogue between government and society - in public and plural canals - as condition for an allocation more efficient joust and of the public resources. In this context the present study it objectified to understand from readings of the performance of represented group of bencheses the dynamics of functioning of the Tourist Conselho Pólo Costa das Dunas while space of participation and social control. The bibliographical research contemplated diverse sources in order to compile knowledge of credential authors in the quarrel of inherent subjects to the civil society and the public sphere to the construction of the citizenship to the conception formation and dynamics of the social control through Conselho of public politics. A qualitative perspective the case study was adopted as research method and for attainment of the data interviews with the members of the Conselho had been carried through beyond consultation the referring documents the dynamics of functioning of the Conselho. The profiles capacities and limitations of the members of the Conselho had been identified constitution social and dynamic organization of functioning of the Conselho and the readings of the members of the Conselho concerning the power to decide instances and participation. The results had shown that the allotment of being able in the Conselho does not occur of equal form. The functions of coordination of the activities of the Conselho are assumed by the representatives of the public agencies. Level of qualification of council members also if presents as difficulty to development of activities of Conselho since the majority of the interviewed ones disclosed unreliability and unfamiliarity when thematic specific that runs away from its organizacional reality they are boarded in the assemblies. Of this form the Conselho if presents more as half of institutional legitimation of what half of characterization of the creation of a public sphere properly said. Finally he could himself be concluded that a democratic culture inexists that inside crosses practical the institutional ones of the Conselho thus limiting the possibility to reach the effective social control of the public politics of tourism in the Rio Grande do Norte

This work is a case study based on Belém Jewelry Pole, whose main issue is to understand how the social network (which the Pole is inserted) influences on innovation process on this area. The main objective is to analyze how interorganizational networks impacted/impact on the potential for innovation, creating both limits and opportunities for the companies development. The adopted method analyzed the historical jewelry industry trajectory since the beginning of mineral extraction in the city of Itaituba (in the Pará State) until nowadays. Primary and secondary data were used allowing the view of the dynamics of the network during transformation periods of the main involved actors in the process. The prospect of embeddedness structural as analysis technique allowed verifying the quality of interactors ties, as well as the visualization of their structures. During the jewelry industry trajectory was verified a change in the quality of social relations, modifying the information flow, trust and associations of various links in the production chain. Both direct and indirect ties facilitated the access to remote networks entering new information related to new products, processes and market aspects. This interaction has led to raising the innovation potential causing a qualitative and quantitative improvement in competitiveness of organizations. Some embedded ties allowed the formation of partnerships bringing various economic earnings for those involved in the relationship. Thus, it is understood how aspects related to the position, architecture and quality of ties in a wide social network influenced on the innovation process and eventual jewelry industry trajectory

A prática regular de exercício físico possibilita redução dos efeitos das disfunções hormonais e envelhecimento biológico natural que promovem desajustes hemodinâmicos, vasculares e músculo-esqueléticos, principalmente na população feminina no período pós-menopausa. Nesta fase da vida, o exercício aquático representa mais do que uma forma de ajuste funcional, é uma forma de manutenção de independência para as atividades da vida diária (AVD s) e melhoria na qualidade de vida. Este estudo teve como objetivo avaliar as modificações adquiridas pela prática regular de um programa de exercício aquático concorrente de intensidade moderada no nível de óxido nítrico (ON), no índice de resistividade arterial (IR), no perfil lipídico, na capacidade funcional e na qualidade de vida de idosas. A amostra foi formada por idosas (60 a 80 anos) selecionadas por randomização, por sorteio simples divididas em grupo controle e grupo de intervenção as quais foram submetidas a um programa de exercícios aquáticos proposto inicialmente em projeto piloto, por 12 semanas (n=34) e o ensaio clínico teve duração de 16 semanas (n=40). Foi coletada amostra sanguínea das idosas e avaliado o perfil lipídico pelo método enzimático com kit Labtest e o ON por medida indireta a partir da concentração de nitrito no sobrenadante das células em cultura em leitor de ELISA. A avaliação das artérias carótidas e vertebrais foi feita utilizando o método de ultra-som Doopler. A capacidade funcional foi avaliada por quatro testes que simulam atividades da vida diária que são: caminhar 10 metros (C10m), levantar da posição sentada (LPS), levantar da cadeira e locomover-se pela casa (LCLC) e o de levantar-se da posição decúbito ventral (LPDV). No estudo piloto foi avaliado o índice geral de autonomia funcional (IG) e a qualidade de vida através do questionário WHOQOL-100. Empregou-se a análise de variância (ANOVA) com medidas repetidas nos fatores grupo (GH e GC) e tempo (pré e pós-teste) para as comparações intra e intergrupos nas variáveis seguida do post hoc de Scheffé. Utilizou-se o teste de correlação de Pearson e adotado o valor de p<0,05 para a significância estatística. Houve aumento do ON circulante, redução nos índices de resistividade arterial, melhoria significativa nos níveis de colesterol e triglicérides e ganho na capacidade funcional das idosas após a intervenção. Existiu correlação inversa entre a resistividade da artéria vertebral direita (VERTD) e níveis de ON e entre a VERTD e os níveis plasmáticos de HDL, assim como entre estes e o teste C10m nas idosas em estudo. Não houve modificações significativas na qualidade de vida das idosas. Em conclusão, o programa de exercício proposto foi capaz de oferecer melhorias funcionais, aumentar o nível de óxido nítrico circulante, diminuindo a resistência arterial promovendo modificações no perfil lipídico de idosas

It treats tourism as part of the places urban development dynamics and the touristic urbanization process as a strategy of cities international competitiveness strengthen, detaching institucional agents role as promoters of this process. It aims to understand how happens the interinstitucional cooperation existing between the agents (Estate, private initiative and third sector) that composes the Development Council of Pólo Costa das Dunas/RN, littoral potiguar region, where are invested the resources deriving from the Program of Development of Tourism in the northeast of Brazil (PRODETUR/NE). Making use of economy referencials, urban sociology and urban geography, as a possibility of a more consistent theoretical construction, capable to accomplish the sustainable development and sustainable tourism concepts amplitude, this work brings out an experience of interinstitucional cooperation, where it glimpses itself the possibility of implementation of a alternative development model, based on the sustainability principles

The object of this study involves the eolian energy and the scenario the training of wind pole in Rio Grande do Norte. The aim is to investigate how far the implementation of the potiguar eolian pole may represent a regional development policy with real change in the structure of the traditional local productive base. About the interaction between the public and private to development of the local eolian activity, the hypothesis is that there is no coordination between the sectors responsible for eolian activity in the state. The theoretical approach follows the developmental current and theory of growth poles, and methodology adopted is a search of exploratory and documentary, with analysis of relevant documents on the subject. As a result of the study it was found that owing to the fragility of the productive structure potiguar and imbalances produced by the concentration of capital in the Northeast, the eolian activity in the state, needs a greater state-owned intervention to ensure a basis of development based on the study and strengthening local productive chain

This work studies the thematic of the politics of formation of teachers in the Program of Professional Qualification for Basic Education (PROBÁSICA) developed in the City of Parnamirim, Rio Grande do Norte. It has as its main objective to identify and to analyze the contribution of this politics of initial formation for the professional formation of teachers. To install the work, we will use the procedures of bibliographical research, documentary analysis, comment, structuralized interview, questionnaire-script and virtual research. In the analysis of the data, we trace a general view on PROBÁSICA while initial formation along with the continued formation, pedagogical research, collaborative research and the exercise of the teaching profession, identifying the possibilities and limits of the Program in the direction to reach the objective considered in this work. From the inquiry, we construct the institutional land scope of the program in question, also focusing, the organizational aspects of its functioning. We have to take care about the results, we evidence that PROBÁSICA is making the possible to access of the teachers in the educational service to the University, what the main aspect that consists, trying to prove eminent weak points in its systematic due to give to the organizational structure of this educational politics that does not count with curricular, institutional and financial the necessary conditions for the success of the professional formation of the teachers. The research will try to understand that the operationalization of the politics of formation in Parnamirim will be belong with it the main idea of the Educational Reformation in years of 1990, articulated to the neoliberal interests, that the responsibility for the problems of the public system of education attributed to the teachers, and that are not answered completely through the purpose of the professional formation, and ti seems that it does not define one global national politics that deals with seriousness to the questions the initial formation, permanent formation, pedagogical research, , career and conditions of work for the teachers

Dois estudos foram conduzidos com o objetivo de avaliar os efeitos da aplicação de chama no controle de Eichhornia crassipes, Brachiaria subquadripara, Pistia stratiotes e Salvinia auriculata. No primeiro estudo foram utilizadas diferentes doses de chama, representadas pela quantidade de gás consumida durante a aplicação, e, no segundo, usaramse duas aplicações de chama em intervalo de 14 dias, uma aplicação seqüencial (intervalo de sete dias) e aplicação única. As diferentes doses, tanto no primeiro quanto no segundo, foram comparadas com plantas que não receberam nenhum tratamento térmico. Avaliações de injúria foram realizadas aos 1, 3, 7, 10, 14, 17, 21 e 30 após a aplicação dos tratamentos, sendo realizadas também avaliações das biomassas secas das plantas aquáticas remanescentes em cada tratamento, ao final dos ensaios. No primeiro estudo foram observadas reduções significativas na produção da biomassa seca das espécies E. crassipes, B. subquadripara e P. stratiotes tratadas com as maiores doses referentes aos consumos de gás. Doses menores não diferiram estatisticamente da testemunha quanto à produção de biomassa seca, exceção feita para a espécie P. stratiotes. Todas as aplicações seqüenciais proporcionaram redução acima de 90% na produção da biomassa seca de E. crassipes e B. subquadripara. As aplicações seqüenciais e únicas proporcionaram reduções abaixo de 37% na produção da biomassa seca de S. auriculata. Os resultados demonstraram que existe a possibilidade de se utilizar o controle físico através da aplicação de chama como alternativa no manejo de plantas daninhas em ambientes aquáticos.

No ecossistema aquático há uma faixa de umidade gradiente no solo que interfere diretamente na ocupação das espécies à margem da lâmina de água. Essa zonação ecológica reflete os graus de adaptação que as plantas apresentam para tolerar o alagamento ou a dessecação. O presente trabalho visou apresentar a análise morfoanatômica de cinco espécies de Cyperaceae encontradas em diferentes zonas no entorno da represa Alagados, em Ponta Grossa-PR, Brasil: Cyperus giganteus, Rhynchospora corymbosa var. aspérula, Cyperus densicaespitosus, Cyperus rigens e Eleocharis sp. Estruturas caulinares e foliares das cinco espécies de Cyperaceae foram analisadas a partir de cortes histológicos. Concluiu-se que, das cinco plantas analisadas, somente três caracterizam-se como plantas aquáticas, sendo duas classificadas como plantas emergentes e uma como submersa fixa devido às características adaptativas que apresentam para obter sucesso nesse ambiente.

The continuous inputs from agriculture areas and human or industrial sewer have been provided a widely demographic explosion of tropical tanner-grass and para grasss plants in the rivers and water reservoirs of Brazil. Considering the importance of these noxious weeds there is a vast necessity of basic studies on aspects related to reproduction, growing, development, nutritional requirements, responses to control systems and others. In most studies, leaf area knowledge is crucial and it is one of the most difficult characteristics to be measured because it usually requires expensive equipments or it uses a destructive technique. The objective of this work was to develop equations for leaf blade dimensional parameters to allow determination of the leaf area of African tanner-grass (Brachiaria subquadripara (Trin.) Hitchc) and para grass (Brachiaria mutica (Forsk.) Stapf.). Correlations between real leaf area and dimensional parameters of leaf blade such as length along the main vein (L) and maximum width (W) perpendicular to the main axis were studied. Only the linear equations allowed a good leaf area estimate. It is suggested to opt for a simple linear equation involving respective products of length times maximum width considering linear coefficient equal to zero. Thus, B. subquadripara (SS) and B. mutica (SM) non destructive leaf blade area estimates may be performed by the following formulas: SS = 0.7719 (L x W) and SM = 0.7479 (L x W), with coefficients of determination (R(2)) of 0.9594 and 0.9408, respectively.

Physical Exercise (PE) is a necessary component in the management in COPD patients, where respiratory symptoms are associated with reduced functional capacity. Even with the increase in the number of studies that have been published and the therapeutics success using aquatic therapy approach, studies using PE in water in COPD patients are so few. Objective: the aim of this present study was to analyze the effects of low intensity water exercise in COPD patients, developed in two different places aquatic and ground. Methods: This is a randomized clinical trial study, 42 patients with moderate to very severe DPOC were recruited for the study, mean age of 63,2  10,9 years old. Randomized in 3 groups: Control Group (CG), Land Group (LG) and Water Group (WG). The PE protocol was performed in a period of 8 weeks, with frequency of 3 times per week. The CG participated in an educational program. All the patients were assessed twice through spirometry, respiratory muscular strength, the 6-min walk test, the quality of life (SF-36 and SGRQ), the LCADL, the MRC, the BODE index and the upper limbs (UP) incremental test. Results: There was a significant difference after the approaches in DP6 from the WG (p=0,02); in VEF1 in LG (p=0,00) and WG (p=0,01); in MIP in LG (p=0,01) and WG (p=0,02); in MEP in LG (p=0,02) and WG (p=0,01); the MRC decreases in WG (p=0,00). there was an increase of the weight supported by the UP in LG (p=0,00) and WG (p=0,01). The LG showed an increase of the quality of life represented by the SGRQ total score (p=0,00). The BODE index decreased in LG (p=0,00) and WG (p=0,01). In LCDAL, the LG showed a decrease. Conclusion: This data in this present study suggest that both approaches of low intensity exercise showed to be beneficial in moderate to very severe COPD patients. The WG showed additional benefits in physical function, pointing to a new therapeutic modality for COPD patients

The contamination of the waters resources for wastewater from industrial, agricultural, and domestic sources is a serious environment problem, compromising its use for human consumption and agriculture. The Extremoz-RN Lake is an important freshwater source for the supply of the city of Natal, supplying a population of approximately 160,000 habitants. This aquatic body is located near an industrial pole which can be a serious risk factor for quality of its waters. The objectives of this study were examined the genotoxicity of Extremoz Lake between September of 2006 and January of 2008, by a combination of the Allium micronucleus test, piscine micronucleus test and the comet assay in erythrocytes from peripheral blood of Oreochromis niloticus. Additionally, the level of eight different heavy metals was quantified through spectrometry of atomic absorption of flame. The Allium test did not detect increase in the frequencies of micronucleus in none of the analyzed periods, however a strong cytotoxic activity was demonstrated for decrease in mitotic index in the analyses carried in April and July of 2007. Negative results had been detected in the frequencies of micronucleus in O. niloticus. A statistic significant increase was observed in the levels of DNA damage in comet assay carried in July of 2007. The results of the chemical analysis had detected increase in the levels of cadmium, chromium, copper, nickel, lead and zinc in different periods. These results demonstrated an alteration of the water s quality of the Extremoz Lake caused for the contamination for heavy metals and increase of DNA strand breaks. The use of biomonitoring program of the heavy metal and other pollutants with genotoxic potential combinated with genotoxicity assays is recommends.
