Entre o mar e estrela, um lugar para se bem viver : a problemática da expansão urbana da Cidade de Baía Formosa/RN

The urban expansion problem of Baía Formosa, a southern edge city of de Rio Grande do Norte eastern coast, which has been presented in other coast Brazilian towns, specially on those with tourist activities increase. Therefore, this situation brings huge concerns to their inhabitants, to their technical /scientific community and to the governments, because of the conflicts of interest and of the growth of urban problems that this has been created. At Baía Formosa, the situation is aggravated because the city is confined, once around it, there are large private proprieties, environmental preservation area and the sea, at the eastern edge. The objectives of this study are the analyses of this city expansion process in order to obtain adequate alternatives and defining methodology to apply in other urban nucleus that are subjected to similar situations. Of course, presents social relations, environmental conditions and promoting local population insertion should be considered in order that enjoin this process and contributing to a better social balance. This case study has used bibliography research, field data, maps and soil occupation recorders and photographs of the area, besides the primary data gathering by surveys carried out with many social actors. The present analysis shows that the urban expansion observed today is featured by a recent unsustainable model, which attacks the environment and brings either farm conflicts. On the other hand, the ecological tourism can represent an alternative in order to achieve an adequate expansion form, without forgetting the several structural parameters necessary to support the sustainable activities

Parâmetros do metabolismo oxidativo na anêmona-do-mar Bunodosoma cangicum: variação sazonal e efeitos da exposição ao ar

Bunodosoma cangicum é uma anêmona-do-mar que habita a faixa intermarés nas regiões sul e sudeste do Brasil. Assim como outros animais característicos destes locais, esta espécie de anêmona enfrenta diariamente as mudanças nos parâmetros ambientais decorrentes do ciclo de marés, os quais podem variar conforme a estação do ano. Estas mudanças podem alterar o metabolismo oxidativo dos animais destes habtats, que pode também ser influenciado pelas diferentes estações ao longo do ano. Portanto, a influência de dois períodos distintos durante o ano além da exposição ao ar sobre parâmetros oxidativos (Capacidade antioxidante total contra radicais peroxil - ACAP, atividade da glutamato cisteína ligase - GCL, conteúdo de glutationa reduzida - GSH e nível de perxidação lipídica - LPO) foi avaliada em anêmonas-do-mar coletadas em situação de submersão ou de emersão em um perío do frio e um quente (final de inverno/começo de primavera e início de outono). A resposta destes parâmetros, bem como do conteúdo de espécies reativas de oxigênio (ERO) e de adenosina trifosfato (ATP), também foi avaliada em animais submetidos diariamente à exposição ao ar (3 h) em laboratório por 30 dias. Com relação aos parâmetros oxidativos considerando apenas os diferentes períodos do ano, uma maior atividade da GCL foi observada durante o período mais frio, assim como um maior nível de LPO neste mesmo período. Com relação à exposição ao ar, no que diz respeito às defesas antioxidantes, em animais coletados em emersão foi observado uma maior atividade da GCL durante o período quente, além de uma maior ACAP e um menor conteúdo de GSH em anêmonas-do-mar coletadas, tanto no período frio como quente. Com relação aos danos oxidativos, um maior nível de LPO foi encontrado em anêmonas-do-mar coletadas durante emersão no período mais (outono). De forma geral, não foi observado um padrão de variação dos parâmetros oxidativos em função da hora do dia, evidenciando-se apenas uma diminuição na ACAP e um aumento da GSH, em torno das 13h, em animais coletados durante a estação mais quente. As 7 anêmonas-do-mar expostas ao ar sob condições controladas de laboratório mostraram variações transitórias da ACAP (aumento) e do conteúdo de GSH (redução) após a reoxigenação. Estes resultados indicam que alguns parâmetros oxidativos de B. cangicum apresentam variação sazonal enquanto outros são afetados pela exposição ao ar. No entanto, o padrão de resposta destes parâmetros é diferente em campo e em laboratório, sugerindo que os parâmetros controlados em laboratório, tais como temperatura, fotoperíodo e iluminação, modificam a resposta do metabolismo oxidativo de B. cangicum à exposição ao ar em campo.

El mar y la mediterraneidad en la narrativa de Elsa Morante

This doctoral Thesis aims to approach the philosophical significance of the Italian author Elsa Morante, expressed through poetic narrative of her second great novel L'isola di Arturo (1957). For this reason, the inductive knowledge has been opted, which can be reached through the symbolic study of the sea and the mediterranean. From the philosophical and psychoanalytical research from such authors as Mircea Eliade, Gaston Bachelard and Carl Jung, linked to the circle of the Eranos Foundation in Switzerland, where the most rigorous multidisciplinary science theories of nature and man converged, and the Grenoble imaginary Center of Research, driven by anthropologist Gilbert Durand in 1966, a revealing investigation of aquatic and marine image has been carried out. In this context of convergence, the work Las estructuras antropológicas del imaginario by Durand, has fulfilled the important catalytic role, of both the Renaissance conception that wants to observe certain universal components in the symbolic vision that nourishes literary expression, as well as the compilation of large images that illuminate the human imaginary of all time. Objectives and results In this regard, it has been considered that the appropriate approach to morantiano imaginary, could only be done thoroughly, based on a repertoire of images as complete as possible, which, if performed from the anthropological compendium of people and civilization of the world, it is offered as a study backed by profound consistency which is the basis of the method. Therefore, it is said, the imaginary is studied and understood through itself. Thus, the internal coherence of this method is seen to be configured as a form of knowledge of human thought because research, from the symbolic point of view, dissects reality in various ways, however, the most seductive is to consider the possibility of an internal coherence between them to converge at a common conclusion which includes all of them. This fact determines the systematization which is shown in the first part of this thesis, as the image and symbol have a close homogeneity between the signifier and the meaning, so that metaphorical expression is established as the structuring element of the human imaginary and the literary representation...

El ejercicio y el desempeño musical: doce semanas de actividad física mejoran la capacidad de ejecución de un instrumento musical en estudiantes de conservatorio

Con el fin de evaluar los cambios que produce un programa de actividad física en la percepción que tienen los músicos sobre su capacidad de ejecución de un instrumento musical, se realizó una intervención con un programa de actividad física basado en la técnica Pilates, durante 12 semanas, en el Conservatorio de Música de la Universidad Nacional de Colombia, con estudiantes del programa de música instrumental. Se midieron parámetros de la aptitud física (capacidad cardiorrespiratoria, fuerza, flexibilidad y composición corporal) y de la percepción de la capacidad de ejecución (fatiga muscular, nivel de esfuerzo, dolor y fluidez) antes y después de la intervención. Los resultados arrojaron cambios positivos en la aptitud física logrando un aumento significativo en la flexibilidad y resistencia de los miembros inferiores en 14 participantes (70% de la muestra), y en la percepción de la capacidad de ejecución instrumental con el retraso en la aparición de la fatiga muscular mientras se está ejecutando el instrumento (30 minutos en promedio). Esto permite a los músicos abordar un repertorio extenso con menor fatiga, minimizando el riesgo de lesión o alteraciones musculo-esqueléticas que influyan directamente en su desempeño técnico y artístico.

Asfixia perinatal y proteína S100B

La asfixia perinatal es la principal causa de muerte en la primera semana de vida la nivel mundial, los niños que sufren esta complicación y sobreviven pueden presentar trastornos neurológicos de diferente nivel de compromiso que inciden en su desarrollo personal y social. Las cifras de muerte por este problema de salud han disminuido de manera importante, sin embargo en el reporte de la Organización Mundial de Salud (OPS) del 2010, la asfixia perinatal es causa del 29% de muertes infantiles en los países de América Latina y el Caribe 2. Es necesario conocer además la extensión del daño neurológico que sufren estos niños, con este fin se desarrolló un estudio piloto en el Hospital Universitario Mayor Mederi de Bogotá, en el cual se determinó la concentración de un marcador metabólico de daño cerebral, la proteína S100B en suero de 60 recién nacidos sanos, con el objetivo de analizar la asociación del mismo con el peso al nacer, la edad gestacional y el diagnóstico. Los resultados no mostraron diferencias significativas entre este marcador y las variables analizadas que puede asociarse al pequeño número de pacientes, sin embargo han sentado las bases para el desarrollo de un estudio que incluya varios hospitales de Bogotá y sobre todo la determinación del mismo en recién nacidos con diagnóstico de hipoxia en el período perinatal, lo cual aportará información del grado de la alteración que puedan tener a nivel cerebral y contribuya al mejor manejo evolutivo con la aplicación de medidas de intervención en estadios tempranos de la vida.

Fluxo de calor, fusão do gelo e nível do mar

The recent values of heat flow data obtained for Greenland and West Antarctica are higher than it was supposed. In West Antarctica, values higher than 200mW/m2were found (Schroeder et al,2014) and in Greenland, values higher than 140 mW/m2 were detected in the Central part (Petrunin et al,2013). Thermal conductivity values of ice are relatively low at atmospheric pressure. This means that if we consider heat flowing by conduction, near the surface of the globe, with this heat flow values, the thermal gradients mill be elevated. A possible reason presented for the high heat flow values in Greenland is the existence of a thin lithosphere. The study of the ice melting near the poles is related with the changes in sea level. Obtaining this parameter is difficult. The time interval with measurement is not enough to obtain clear information about the past..The spatial distribution of heat flow shows clearly zones in the oceans with high values. How can this heat influence water movements in that regions and the temperature in the oceans?

How can land and urban development make houses healthier?

Traditionally, the main focus of the professional community involved with indoor air quality has been indoor pollution sources, preventing or reducing their emissions, as well as lowering the impact of the sources by replacing the polluted indoor air with "fresh" outdoor air. However, urban outdoor air cannot often be considered "fresh", as it contains high concentrations of pollutants emitted from motor vehicles - the main outdoor pollution sources in cities. Evidence from epidemiological studies conducted worldwide demonstrates that outdoor air quality has considerable effects on human health, despite the fact that people spend the majority of their time indoors. This is because pollution from outdoors penetrates indoors and becomes a major constituent of indoor pollution. Urban land and transport development has significant impact on the overall air quality of the urban airshed as well as the pollution concentration in the vicinity of high-density traffic areas. Therefore, an overall improvement in indoor air quality would be achieved by lowering urban airshed pollution, as well as by lowering the impact of the hot spots on indoor air. This paper explores the elements of urban land and vehicle transport developments, their impact on global and local air quality, and how the science of outdoor pollution generation and transport in the air could be utilized in urban development towards lowering indoor air pollution.

Capabilities : describing what services can do

The ability of agents and services to automatically locate and interact with unknown partners is a goal for both the semantic web and web services. This, \serendipitous interoperability", is hindered by the lack of an explicit means of describing what services (or agents) are able to do, that is, their capabilities. At present, informal descriptions of what services can do are found in \documentation" elements; or they are somehow encoded in operation names and signatures. We show, by ref- erence to existing service examples, how ambiguous and imprecise capa- bility descriptions hamper the attainment of automated interoperability goals in the open, global web environment. In this paper we propose a structured, machine readable description of capabilities, which may help to increase the recall and precision of service discovery mechanisms. Our capability description draws on previous work in capability and process modeling and allows the incorporation of external classi¯cation schemes. The capability description is presented as a conceptual meta model. The model supports conceptual queries and can be used as an extension to the DAML-S Service Pro¯le.
