Turismo cultural na ZEPH-Ribeira: possibilidades e limitações

Considering that urban interventions, planned and executed recently at Natal, RN, should put Ribeira - one of the town centers - in the new limits of the expanded center of the city, this work examines the use of this new accessibility for the benefit of the development of an infrastructure to support a type of tourism currently seen as an alternative to diversification into areas dominated by entertainment tourism (the case of Natal). A local with city's traditional cultural facilities and holder of a set built that is a synthesis of the images of the neighborhood, it fears that this increase in the potential for movement and flows of use stimulate speculation and deployment of a bulk type of activity incompatible with the preservation the architectural heritage. Important economy for the city, tourism has been showing a factor propellant processing urban related changes in accessibility. It is argued that cultural tourism, often used in plans and projects of revitalization across the country, may be factor for sustainable development and conserve the assets, and contributes to the process of revitalization of the historic cultural center as Ribeira. Intended to illustrate the need to consider other information that might help in the revitalization of the neighborhood, this research presents the offer cultural tourism of Ribeira and identifies and maps certain physical attributes that, combined with functional attributes, can stimulate or inhibit the diversity and vitality in the region

Desenvolvimento e caracterização de um sabonete contendo borras de café

Desde da antiguidade que o ser humano se preocupa com a sua aparência externa, em especial com a pele. Para além do desenvolvimento de cosméticos, surgiram também produtos mais complexos, os cosmecêuticos, que diferem dos cosméticos devido a poderem influenciar a função biológica da pele, causando modificações positivas e duráveis. O conceito de sustentabilidade é usado para definir ações e atividades humanas que visam suprir as necessidades atuais dos seres humanos, sem comprometer o futuro das próximas gerações. Ou seja, a sustentabilidade está diretamente relacionada ao desenvolvimento económico e material sem agredir o meio ambiente, utilizando os recursos naturais de forma inteligente para que eles se mantenham no futuro. Seguindo estes parâmetros, a humanidade pode garantir o desenvolvimento sustentável. As borras de café são consideradas como um subproduto alimentar, sem grande reutilização, o que promove danos no impacto ambiental. Por outro lado, as borras de café podem exercer grandes benefícios para a pele, pois são consideradas excelentes exfoliantes naturais com propriedades refirmantes. Os produtos à base de cafeína são aliados no combate à celulite, na estimulação da regeneração celular e da circulação sanguínea, bem como, no rejuvenescimento e revitalização da pele. Este trabalho consistiu no desenvolvimento de um sabonete, contendo borras de café, como forma de reaproveitamento de um subproduto alimentar rico em cafeína, com o intuito de obter produtos com boas propriedades cosméticas e elevada estabilidade física e química. As borras de café foram analisadas em termos da sua estabilidade física e química através de ensaios de estabilidade acelerada por centrifugação, textura, reologia e doseamento do teor de cafeína por HPLC. Os resultados obtidos através do controlo físico-químico dos sabonetes, da determinação do potencial irritante cutâneo e da análise sensorial efectuada em voluntários humanos, demonstraram que é possível preparar sabonetes de borra de café com boa estabilidade físico-química, boa tolerância cutânea e com características sensoriais adequadas, utilizando uma base de sabão constituída pelos ingredientes (INCI): Sodium Palmate, Sodium Palm Kernelate, Aqua (water), Glycerine, Fragância de café, Sodium Chloride, Butyrospermum Parkii Butter (Shea Butter), CI 778911 (Titanium Dioxide), Tetrasodium EDTA, CI 77499, Linalool e à qual foi adicionada 5% de borras de café.

Mobilidade urbana sustentável em projetos estruturantes: analise urbanística e ambiental do corredor de transporte da Avenida Bernardo Vieira Natal/RN

The search for a sustainable urban mobility, has recast the public policy of transport and movement for all, in order to contribute to the welfare economic, social and environmental. Within this context, has as its main objective review here in the city of Natal in the state of Rio Grande Norte, the deployment of the new road infrastructure of the transport corridor of Bernardo Vieira Avenue and checking at least with regard to urban areas and environmental chosen here, as will indicators to assess sustainable urban mobility, that the theory has been well constructed, but in practice little way to apply the proposed guidelines for sustainability. To achieve this result, is initially a literature review with the principal investigators of the matter, since the concepts of indicators of sustainable urban mobility. And a second time, participating in to the case study, using the methodology of environmental awareness, through analysis photographs, notes and testimony in the study area ace to reach conclusions

Natureza morta...edifício com vida: uma arquitetura sustentável para o Serviço de Verificação de Óbitos

Sustainability in buildings, while reducing the impact on the environment, contributes to the promotion of social welfare, to increase the health and productivity of occupants. The search for a way of build that meets the aspirations and development of humanity without, however, represent degradation of the environment, has become the great challenge of contemporary architecture. It is considered that the incorporation of principles that provide a sustainable building with careful choices of design solutions contribute to a better economic and thermal performance of the building, as well as functional and psychological comfort to its users. Based on this general understanding, this paper presents an architecture project aimed to health care whose the solutions adopted follow carefully the relevant legislation and sets his sights on the theme of sustainability. The methodology began with studies on the themes of verification service of deaths, sustainability and those application in construction developed through research in academic studies and analysis of architectural projects, using them like reference for the solutions adopted. Within the project analysis was performed a visit to the verification service of deaths in the city of Palmas in Tocantins, subsidizing information that, plus the relevant legislation, led to functional programming and pre-dimensional of the building to be designed. The result of this programming environments were individual records with information from environmental restrictions, space required for the development of activities, desirable flow and sustainability strategies, that can be considered as the first product of relevance of the professional master's degree. Finally we have outlined the basic design architecture of a Verification Service of Death SVO/RN (in portuguese), whose process of projecting defined as a guiding line of work four points: the use of bioclimatic architecture as the main feature projectual, the use of resources would provide minimal harm to the environment, the use of modulation and structure to the building as a form of rationalization and finally the search for solutions that ensure environmental and psychological comfort to users. Importantly to highlight that, besides owning a rare theme in literature that refers to architectural projects, the whole project was drawn up with foundations in projective criteria that contribute to environmental sustainability, with emphasis on thermal performance, energy efficiency and reuse of rainwater

Efeito dos nutrientes (nitrogênio e fósforo) sobre o desenvolvimento da Gracilaria birdiae: crescimento e possível uso como biofiltro

Marine shrimp farming has grown exponentially during the last years in Brazil. In spite of the promising economical situation, this activity is facing an increasing criticism due to its environmental impact. Thus, the necessity of alternatives to mitigate environmental degradation caused by this activity. An alternative that is being studied is the policulture that is the integrated culture of two or more organisms, normally one of them a filtering organism. Among filtering organisms, macroalgae are very practicable because they are efficient in the removal of the exceeding nutrients of the water and do not leave residues in the water. Besides, the integrated culture with macroalgae allows the economical exploration of the seaweed (for the manufacture of jelly and jam, for the dairy industry, pharmaceuticals, etc.) along with possibility of a sustainable aquaculture. In the present experiment, the development of the seaweed Gracilaria birdiae, the influence and tolerance of this species to the environmental parameters, and its absorption efficiency in relation with the three kinds of macronutrients (NH4+, NO3- and PO4-3) found in the effluents of marine shrimp farming was studied. The experiment was divided in two parts: a laboratorial part and one part carried under natural conditions. The water used in the laboratory trial was collected in the shrimp ponds of Tecnarão farm and distributed in aquaria containing 20 g of G. birdiae. In the field trial, 0.5 kg of G. birdiae was inserted in PVC cages cultivated in the farm. The results of the study showed a modest growth of G. birdiae, probably due to its low tolerance to highly eutrophicated environments. However, the removal of nutrients was very expressive. Ammonia was reduced in approximately 34 %. Ortho-phosphate showed a reduction of 93.5 %. The capacity of biofiltration of the NO3- by the macro algae was of 100 %, showing that G. birdiae is a seaweed-filtered with a high level of removal for this nutrient under laboratorial conditions. In spite of the low growth of the macro algae in the experiment, the results in relation to the removal of nutrients of the water was encouraging, suggesting that this species can be an efficient biofilter and thus, a strong candidate to be used in a sustainable aquaculture

Desenvolvimento e validação de método para determinação do perfil graxo do biodiesel de Tungue e Blendas com soja empregando GC-MS

No Brasil o biodiesel é utilizado em misturas com óleo diesel em proporções de 5%, sem que haja modificações nos motores. Com o intuito de diversificar a utilização de oleaginosas não comestíveis no ramo dos biocombustíveis, e ainda vincular a produção com agricultura sustentável, uma alternativa para o RS é a utilização do óleo de tungue para a produção de biodiesel. A caracterização e quantificação de ácidos graxos do biodiesel de tungue, torna-se importante devido à seu exclusivo perfil graxo. Neste trabalho, foi estudado o desenvolvimento e validação de método para a determinação do perfil graxo do biodiesel metílico de tungue e blendas com soja utilizando GC-MS. Os parâmetros de validação considerados foram: curva analítica, linearidade, seletividade, limite de detecção e quantificação, robustez, precisão e exatidão. Para determinar as melhores condições cromatográficas, foram testadas diferentes programações de temperatura no forno cromatográfico; fluxo de gás; temperatura do injetor, detector e interface; e modo de injeção. As condições do GCMS após a otimização foram: injeção de 1 µL com injeção em alta pressão (300 kPa), T do injetor: 250 ºC, injeção split 1:30, fluxo de 1 mL min-1, coluna Rtx-5MS com dimensões 30 m x 0,25 mm x 0,25 µm, T forno: isoterma de 2 min a 130 ºC, aumento de 20 ºC/min até 220 ºC, aumento de 0,5ºC/min até 223ºC, aumento de 7 ºC/min até 250 ºC e isoterma em 250 ºC por 3 min, resultando em 20 min de análise. A temperatura da fonte e interface foram de 200 ºC e 250 ºC, respectivamente, com o MS no modo full scan, ionização por impacto eletrônico a 70 eV, e intervalo de massas de 30 a 500 u.m.a. A identificação do α-eleosteárico foi baseada na fragmentação característica do composto, pela comparação com o espectro do ácido linolênico, e ainda pelo tempo de retenção do composto. Na validação, as curvas analíticas apresentaram valores de r maiores que 0,99. O LD e LQ foram adequados, permitindo a quantificação de ésteres na concentração mínima de 0,6%. Os valores de exatidão ficaram entre 86 e 117%, com RSD% menores que 8%. O efeito matriz também foi avaliado, sendo que esse efeito foi considerado médio para a maioria dos compostos, ficando entre ± 20 e 50%. Durante a aplicação do método, o mesmo se mostrou adequado para amostras de biodiesel metílico de tungue e blendas com soja, nas proporções de 15:85, 20:80 e 25:75 (T:S, v/v). A aplicabilidade do método também foi testada para o biodiesel de soja, obtendo resultados satisfatórios, mostrando-se assim, além de tudo, ser um método robusto.

Ação pública na formação e transformação do destino turístico de Porto de Galinhas: um estudo dos referenciais no período de 1970 a 2010

The central interest of this thesis is to comprehend how the public action impels the formation and transformation of the tourist destinies. The research was based on the premise that the public actions are the result of the mediation process of state and non-state actors considered important in a section, which interact aiming for prevailing their interests and world visions above the others. The case of Porto de Galinhas beach, in Pernambuco, locus of the investigation of this thesis, allowed the analysis of a multiplicity of actors on the formation and implementation of local actions toward the development of the tourism between the years 1970 and 2010, as well as permitted the comprehension of the construction of the referential on the interventions made. This thesis, of a qualitative nature, has as theoretical support the cognitive approach of analysis of the public policies developed in France, and it has as main exponents the authors Bruno Jobert and Pierre Muller. This choice was made by the emphasis on the cognitive and normative factors of the politics, which aspects are not very explored in the studies of public policies in Brazil. As the source of the data collection, documental, bibliographic and field researches were utilized to the (re)constitution of the formation and transformation in the site concerned. The analysis techniques applied were the content and the documental analysis. To trace the public action referential, it started by the characterization of the touristic section frontiers and the creation of images by the main international body: the World Tourism Organization, of which analysis of the minutes of the meetings underscored guidelines to the member countries, including Brazil, which compounds the global-sectorial reference of the section. As from the analysis of the evolution of the tourism in the country, was identified that public policies in Brazil passed by transformations in their organization over the years, indicating changes in the referential that guided the interventions. These guidelines and transformations were identified in the construction of the tourist destination of Porto de Galinhas, of which data was systematized and presented in four historical periods, in which were discussed the values, the standard, the algorithms, the images and the important mediators. It has been revealed that the State worked in different roles in the decades analyzed in local tourism. From the 1990s, however, new actors were inserted in the formulation and implementation of policies developed, especially for local hotelkeepers. These, through their association, establishes a leadership relation in the local touristic section, thereby, they could set their hegemony and spread their own interest. The leadership acquired by a group of actors, in the case of Porto de Galinhas, does not mean that trade within the industry were neutralized, but that there is a cognitive framework that confronts the actors involved. In spite of the advances achieved by the work of the mediators in the last decades, that resulted in an amplification and diversification of the activity in the area, as well as the consolidation at the beach, as a tourist destiny of national standout, the position of the place is instable, concerned to the competitiveness, once that there is an situation of social and environmental unsustainability

Controle social do espaço público: uma análise do conselho turístico pólo costa das dunas

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
