Projeto de um edifício para fins educacionais com foco na racionalização do consumo de água

The urban growth without the prior infrastructure has caused many environmental impacts such as the damage to quality of the water resources in the cities. Along with natural scarcity in some regions, this is one of the factors that limit the availability of drinking water. As a result, the conservation of drinking water is becoming one of the major concerns in sustainable architectural projects. Within this context, this dissertation proposes to develop the design of an educational building focusing on water consumption rationalization. The proposed project is located in UFRN Campus at Currais Novos, an area of warm and dry climate and low rainfall. The proposal seeks to integrate ways to reduce water consumption o to architecture, in order to exploit the advantages and savings. After quantifying the benefits achieved, it was concluded that it is possible to reduce significantly the drinking water consumption in educational buildings in universities using three principles: reduction the water consumption at the point of use, replacement of the water source and internal recycling. Calculations and simulations indicated that the proposed building may have water consumption up to 56% lower than if it would be provided by conventional facilities. Rationalization of water consumption brings direct and indirect benefits, with influences on the environmental, social and economic fields

FUNGOS ASSOCIADOS ÀS SEMENTES DE Enterolobium contortisiliquum : ANÁLISE DA INCIDÊNCIA, CONTROLE E EFEITOS NA QUALIDADE FISIOLÓGICA COM O USO DE EXTRATOS VEGETAIS

Os fungos são os principais micro-organismos associados às sementes, podendo causar danos, tanto na fase de campo, como também na pós-colheita e durante o armazenamento. Nesta última fase, a deterioração pode ocorrer pela ação específica de fungos, afetando a qualidade fisiológica das sementes. A utilização de extratos de plantas com propriedades antimicrobianas são alternativas ecológicas e promissoras para substituir a proteção promovida pela aplicação de fungicidas. Objetivou-se nesta pesquisa avaliar a eficiência dos extratos de Allamanda blanchetti e Momordica charantia nas concentrações de 10, 100, 500 e 1000 ppm sobre a micoflora e germinação em sementes de Enterolobium contortisiliquum . As sementes foram coletadas em diferentes municípios do estado da Paraíba (Areia, Arara, Conde e Sobrado). Os lotes foram submetidos a testes de sanidade e de germinação. A avaliação da incidência de fungos foi feita a partir da visualização dos fungos através do método de papel de filtro. Utilizaram-se no teste de sanidade 100 sementes por tratamento, as quais foram imersas em 20 mL dos extratos por cinco minutos, em seguida incubadas em placas de Petri sobre dupla camada de papel de filtro. No teste de germinação utilizaram-se 200 sementes, distribuídas em papel germitest e germinadas à temperatura de 30 ± 2°C. O delineamento experimental utilizado foi o inteiramente casualizado. Constatou-se nas sementes de Enterolobium contortisiliquum os fungos: Aspergillus niger , Aspergillus flavus , Rhizopus stolonifer , Penicillium sp., Curvularia lunata , Nigrospora sp. e Cladosporium sp. Os extratos de Allamanda blanchetti e Momordica charantia nas concentrações de 500 e 1000 ppm causaram redução da frequência dos fungos. O extrato de Momordica charantia nas concentrações de 500 e 1000 ppm proporcionou o aumento na germinação e primeira contagem, além de reduzir o percentual de sementes mortas.

Cooperação e competição entre políticas no Brasil: os custos da governabilidade no presidencialismo de coalizão

Public policies have been studied in the various fields of humanities and social sciences, from different theoretical and technical aspects. However, there is still a lack of studies that incorporate the dimension that encompasses the political action and its interference in such actions, also recognizing the importance of the institutional setting of the Brazilian presidential model in implementing these policies. This fragmented and multiparty system has led to power heterogeneous sets of political parties. Thus, the ministerial offices, more than assisting the President´s government project, manage particularized agendas, which are party biased and have the influence of interest groups in hegemonic themes addressed by government agencies. When these agendas operate in sectoral and specialized policies, the friction level is apparently low. However, when this occurs in intersectoral actions, such as in regional development, there is evidence of strong signs of competition among government agencies, which in theory, should operate in an integrated manner. Although this is not a specific feature of Luiz Inacio Lula da Silva´s government- the period to be studied- there was similar behavior in Fernando Henrique Cardoso´s presidency, one realizes that the expansion of coalition on behalf of governance is increasingly interfering in the outcome of intersectoral public policies, due to these multiple arguments in action. In order to understand these processes, this study focused on the Sustainable and Integrated Development Programme for Differentiated Meso-Regions (PROMESO), part of the National Policy for Regional Development (NPRD). The program provides interface with various government agencies and their public policies in a clear intersectoral design. The research sought to identify and analyze the relationships between government agencies and their programs with interest groups, whether political parties or other segments of civil society, highlighting the logic of favoritism, which poses in second place the integration of actions in the intersectoral policies. Therefore, besides the theoretical debate that incorporates several categories of political science, public administration, public policy, geography and economics, the study focused on secondary sources, using different government agencies databases in order to raise information. It was observed that the interference of partisan politics has been disastrous for some public policies. Thus, the research confirms that cooperative character is fragile within government agencies, often limited to official documents, and that there is indeed, a striking feature of competition, especially when it comes to transversalized policies

Light and dark carbon uptake by Dinophysis species in comparison to other photosynthetic and heterotrophic dinoflagellates

The marine dinoflagellate genus Dinophysis includes species that are the causative agents of diarrhetic shellfish poisoning (DSP). Recent findings indicate that some Dinophysis species are mixotrophic, i.e. capable of both autotrophic and heterotrophic nutrition. We investigated inorganic (and organic) carbon uptake by several species of Dinophysis in the Light and dark using the 'single-cell C-14 method', and compared uptake rates with those of photosynthetic Ceratium species and heterotrophic dinoflagellates in the genus Protoperidinium. Experiments were conducted with water from the Gullmar Fjord and from the Koster Strait (Swedish west coast). Nutrient-enriched phytoplankton from surface water samples were concentrated (20 to 70 mu m) and incubated at in situ temperature under artificial light conditions with high concentrations of inorganic C-14 (1 mu Ci ml(-1)). Individual cells of each desired species were manually isolated under a microscope and transferred to scintillation vials. C. tripes showed net C-14 uptake only during light periods, whereas both C. lineatum and C. furca showed C-14 uptake in the Light as well as uptake (and sometimes losses) in the dark. Dinophysis species had similar carbon fixation rates in Light compared to Ceratium species. For D. acuminata and D. norvegica, net carbon uptake occurred in both Light and dark periods. D. acuta showed a loss of carbon in the dark in one experiment, but in another, dark C uptake was significantly higher than uptake in Light. When exposed to Light, C. furca, D. norvegica and D. acuta had high specific carbon uptake rates. Growth rates for the different species were calculated from C-14 uptake by the cells during the first hours of incubation in light. D. acuminata and D. norvegica had similar maximum growth rates, 0.59 and 0.63 d(-1) (mu); the maximum growth rate of D. acuta was lower (0.41 d(-1)). The positive dark carbon uptake by Dinophysis may suggest a mixotrophic mode of nutrition. In one experiment, both D. norvegica and D. acuta showed a significantly higher carbon uptake in a dark bottle than in a Light bottle, which would be consistent with uptake of C-14-labeled organic matter by D. norvegica and D. acuta. Demonstration of direct uptake of dissolved and particulate organic matter would provide conclusive evidence of mixotrophy and this will require the development of new protocols for measuring organic matter uptake applicable to Dinophysis in the natural assemblages.

Da bancada ao Bureau: análise do desenvolvimento da biotecnologia no Nordeste Brasileiro sob o enfoque de Sistema Regional de Inovação

The starting point of the present work consisted of investigating the development of biotechnology in the Northeast region of Brazil from the perspective of a Regional Innovation System (RIS). The theoretical framework adopted relied on the approaches and concepts presented by the Neo-Schumpeterian perspective. This framework was chosen because, by means of the Innovation System concept, this literature allows us to analyze the relationships and configurations of actors, as well as the role of the state and of social, science and technology, and economic policies in the studied region. The analysis considered four selected dimensions: physical infrastructure, human capital, scientific production, and funding. These variables were chosen because they allow us to verify the possibilities and limitations of developing a biotechnology RIS in the Northeast of Brazil, and these elements would help in answering the question behind this dissertation. The location of the physical infrastructure was determined by means of bibliographic and documental research and interviews with heads of institutions that do biotechnology research. Regarding human capital, the analysis focused on resource training in biotechnology, highlighting graduate courses and research groups in the area. To measure knowledge production, we delimited scientific collaboration among researchers in the field of biotechnology as the focus of this category. For the funding dimension, information was gathered from reports available at the websites of national and state funding agencies. The data was analyzed through method triangulation, involving quantitative and qualitative research stages. To back the analyses, we revisited the integration policies in the area of Science, Technology and Innovation. Our analysis has shown that these policies play a crucial role in the development of biotechnology in the region being studied. The data revealed that the physical infrastructure is concentrated in only three states (Bahia, Ceará, and Pernambuco). In this regard, the Northeast Biotechnology Network (Renorbio) stands out as a strategic actor, enabling states with poor infrastructure to develop research through partnerships with institutions located in another state. We have also verified that the practices involving human resource training and knowledge production are factors that enable the emergence of a regional system for biotechnology in the studied region. As limitations, we have verified the low immersion level of regional actors, the heterogeneity of socioeconomic indicators, the lack of financial resources, and a low innovation culture in the business sector. Overall, we have concluded that the development of a Regional Innovation System in Biotechnology, based on the current regional dynamics, depends on an effective change in the behavior of the social agents involved, both in the national and regional dimensions as well as in the public and private spheres

Fachada flexível para casa padronizada em condomínios

The employment of flexibility in the design of façades makes them adaptable to adverse weather conditions, resulting in both minimization of environmental discomfort and improvement of energy efficiency. The present study highlights the potential of flexible façades as a resource to reduce rigidity and form repetition, which are usually employed in condominiums of standardized houses; as such, the work presented herein contributes to field of study of architectural projects strategies for adapting and integrating buildings within the local climate context. Two façade options were designed using as reference the bionics and the kinetics, as well as their applications to architectural constructions. This resulted in two lightweight and dynamic structures, which cater to constraints of comfort through combinations of movements, which control the impact of solar radiation and of cooling in the environment. The efficacy and technical functionality of the façades were tested with comfort analysis and graphic computation software, as well as with physical models. Thus, the current research contributes to the improvement of architectural solutions aimed at using passive energy strategies in order to offer both better quality for the users and for the sustainability of the planet
