Clima urbano e vegetação: estudo analítico e prospectivo do Parque das Dunas em Natal

The present study deals with the relationship between urban vegetation and climate. The process whereby the Parque das Dunas a 1,172 ha green area in the city of Natal, State of Rio Grande do Norte exerts influence on the climate of the city is analyzed. The hypothesis on which the present work rests is that the green area referred to acts upon the climate of the city. The study is based on the analysis of climatic factors and elements of this green area and of the city of Natal. In order to give rise to final recommendations, a methodology grounded on a quantitative and qualitative standpoint has been used. The data were collected both within and without the limits of the Parque das Dunas area. Secondary and primary data resulting from the measurements taken by the researcher and her work group have been used. The aim was to contribute to the understanding of the influence of vegetation on the climate of a city having a warm and humid climate. A historical and environmental characterization of the Parque das Dunas was then sought. The local climatic factors and the elements of the climate have been studied within the scope of the city of Natal. A comparative study between the climatic elements within and without the limits of the Parque das Dunas area from the survey of technical data and the systematization of the information collected has been made, aiming at proposing a set of bioclimatic recommendations for the urban design in Natal. The results of such work allowed for the validation of the important role that the Parque das Dunas plays in the climate of Natal. This has led to the acknowledgement of the relevance of the green areas on the climate of cities. They bring about important benefits to the process of rendering agreeable the climate in the urban environment by providing pleasant microclimates that give a valuable contribution to the environmental comfort of urban nuclei having the same size of Natal

Ledroit Park, A Portrait In Black And White: A Study Of Historic Districts, Social Change, And The Process Of Neighborhood Placemaking

This research examines the process of placemaking in LeDroit Park, a residential Washington, DC, neighborhood with a historic district at its core. Unpacking the entwined physical and social evolution of the small community within the context of the Nation’s Capital, this analysis provides insight into the role of urban design and development as well as historic designation on shaping collective identity. Initially planned and designed in 1873 as a gated suburb just beyond the formal L’Enfant-designed city boundary, LeDroit Park was intended as a retreat for middle and upper-class European Americans from the growing density and social diversity of the city. With a mixture of large romantic revival mansions and smaller frame cottages set on grassy plots evocative of an idealized rural village, the physical design was intentionally inwardly-focused. This feeling of refuge was underscored with a physical fence that surrounded the development, intended to prevent African Americans from nearby Howard University and the surrounding neighborhood, from using the community’s private streets to access the City of Washington. Within two decades of its founding, LeDroit Park was incorporated into the District of Columbia, the surrounding fence was demolished, and the neighborhood was racially integrated. Due to increasingly stringent segregation laws and customs in the city, this period of integration lasted less than twenty years, and LeDroit Park developed into an elite African American enclave, using the urban design as a bulwark against the indignities of a segregated city. Throughout the 20th century housing infill and construction increased density, yet the neighborhood never lost the feeling of security derived from the neighborhood plan. Highlighting the architecture and street design, neighbors successfully received historic district designation in 1974 in order to halt campus expansion. After a stalemate that lasted two decades, the neighborhood began another period of transformation, both racial and socio-economic, catalyzed by a multi-pronged investment program led by Howard University. Through interviews with long-term and new community members, this investigation asserts that the 140-year development history, including recent physical interventions, is integral to placemaking, shaping the material character as well as the social identity of residents.

Um olhar sobre o patrimônio histórico-arquitetônico de Assú/RN: análise com base na percepção dos usuários e no ponto de vista técnico

This research analyzes the actual Historic-Architectural Heritage of Assú City which is located in Rio Grande do Norte State, Brazil, the study is based on both Assú s residents perception and technician s viewpoint. It looks forward to expose this community s relationship with the existing number of historic buildings, the scale of people s identity to the place and the association of this perception toward the preservation and conservation s scale of the historic settlement. Since the contextualization of the degradation s process of central areas, the study draw nea initially the conceptual aspects, focusing on the debate about heritage and the preservationist practice. The work complements the discussion through an approach on people-environment relationship and environmental perception, considering relevant factors for planning process. The obtained and presented data had diagnosed the condition of the architectural pile and also allowed this work to formulate recommendations for the studied area and architectural set in order to contribute for future urban politics implementation that consider the building, which are not only important to the considered population, but to the Rio Grande do Norte s History, as well

Análise bioclimática do bairro do Renascença II São Luis-MA: realidade e perspectiva do conforto térmico em espaços externos

The present research concerns about outdoor s thermal comfort conditions in hot-humid climate cities, understanding that life quality is a result of the urban object s type built for the human being in an environment with specific climate and morphological characteristics. It is presented as object of study the correlation between the neighborhood Renascença II s microclimate in São Luis /MA-Brazil, hot-humid climate city, and its urban morphological changes. As well as the thermal comfort s satisfaction level of its outdoor users. The research has as general goal to diagnosis the way these transformations caused by the urbanization influence the Renascença II s microclimate, identifying critical spots of the studied area, in order to contribute with land use recommendations based on bioclimatic architecture concepts and supply bases to urban design decisions adequate to the São Luis climate. It is presented as theoretical bases the urban climate, its concepts and elements. After that, the thermal comfort conditioners and its prediction models of thermal comfort sensation in outdoor are presented. The predictive models are presented along with bioclimatic assessment methods. Finally the use of bioclimatic assessment as an effective tool to identify places that need changes or preservation in order to seek environment quality. The applied methodology was based on the studies of Katzschner (1997), complemented by Oliveira s (1988) and Bustos Romero s (2001) studies that suggest an analysis and evaluation of maps of topography, buildings floors, land use, green areas and land covering, in order to overlap their characteristics and identify climate variable s measurements points; then a quantitative analysis of the climate variables (air temperature and humidity, wind speed and direction) of the chosen points takes place. It was perceived that Renaissance II has no permanence areas as squares or parks, its outdoor has little vegetation and presets high land impermeability and built density levels. The majority of the people interviewed said that was comfortable in a range of air temperature between 27,28ºC and 30,71ºC. The elaboration of a neighborhood master plan is important, which defines strategies for improvement of the life quality of its inhabitants

Análisis crítico de la planificación urbana de la Ciudad de Cuenca

Las ciudades de todo el mundo deben mantener un entorno urbano habitable. Nueva York y Barcelona fueron una vez ejemplos a seguir, pero la visión urbana de expansión durante las últimas décadas ha dado lugar a un paradigma que comprende pobremente las tendencias de desarrollo de finales del siglo 20 e inicios del siglo 21. La planificación urbana insuficientemente pondera las aspiraciones de los ciudadanos y las funciones socioeconómicas de la ciudad, generando desequilibrios, caracterizados por el aumento de congestiones de tráfico, injusticia social y económica, y degradación medioambiental. En el caso de la ciudad de Cuenca, el desarrollo urbano ilustra claramente una expansión deficientemente controlada con graves fricciones en los mercados de trabajo y de vivienda, con pocos espacios verdes dentro y alrededor de la ciudad, como fue en el pasado. Este estudio intenta ilustrar la discrepancia entre la teoría y la práctica en el campo de la planificación urbana utilizando como caso de estudio a la ciudad andina de Cuenca. Mientras que la nueva doctrina de planificación urbana habla de un intrincado equilibrio entre las funciones socioeconómicas y ambientales en el espacio urbano, la ciudad se ve cada día más desorganizada. Además, para explicar la situación actual de la planificación de la ciudad de Cuenca, basada en razones teóricas y filosóficas, se identificaron las deficiencias en la planificación urbana. Las buenas prácticas de diseño y planificación urbana deben basarse en una buena comprensión del carácter dinámico y complejo de las ciudades. Con el manuscrito el autor tiene como objetivo impulsar la discusión científica sobre la planificación urbana desde la visión medioambiental y sustentable.

Análise comparativa entre simuladores de linha de fluxo e diferenças finitas para um reservatório de petróleo submetido a injeção de água

Water injection is the most widely used method for supplementary recovery in many oil fields due to various reasons, like the fact that water is an effective displacing agent of low viscosity oils, the water injection projects are relatively simple to establish and the water availability at a relatively low cost. For design of water injection projects is necessary to do reservoir studies in order to define the various parameters needed to increase the effectiveness of the method. For this kind of study can be used several mathematical models classified into two general categories: analytical or numerical. The present work aims to do a comparative analysis between the results presented by flow lines simulator and conventional finite differences simulator; both types of simulators are based on numerical methods designed to model light oil reservoirs subjected to water injection. Therefore, it was defined two reservoir models: the first one was a heterogeneous model whose petrophysical properties vary along the reservoir and the other one was created using average petrophysical properties obtained from the first model. Comparisons were done considering that the results of these two models were always in the same operational conditions. Then some rock and fluid parameters have been changed in both models and again the results were compared. From the factorial design, that was done to study the sensitivity analysis of reservoir parameters, a few cases were chosen to study the role of water injection rate and the vertical position of wells perforations in production forecast. It was observed that the results from the two simulators are quite similar in most of the cases; differences were found only in those cases where there was an increase in gas solubility ratio of the model. Thus, it was concluded that in flow simulation of reservoirs analogous of those now studied, mainly when the gas solubility ratio is low, the conventional finite differences simulator may be replaced by flow lines simulator the production forecast is compatible but the computational processing time is lower.

Carers in the welfare state : on informal care and support for carers in Sweden

  The general aim of this dissertation is to describe and analyse patterns of informal care and support for carers in Sweden. One specific aim is to study patterns of informal care from a broad population perspective in terms of types of care and types of carer. A typology of four different care categories based on what carers do revealed that women were much more likely than men to be involved at the ‘heavy end’ of caring, i.e. providing personal care in combination with a variety of other caring tasks. Men were more likely than women to provide some kind of practical help (Study I). Another aim is to investigate which support services are received by which types of informal caregiver. Relatively few informal caregivers in any care category were found to be receiving any kind of support from municipalities or voluntary organizations, for example training or financial assistance (Study II). The same study also examines which kinds of help care recipients receive in addition to that provided by informal carers. It appears that people in receipt of personal care from an informal caregiver quite often also receive help from the public care system, in this case mostly municipal services. However, the majority of those receiving personal, informal care did not receive any help from the public care system or from voluntary organizations or for-profit agencies (Study II). The empirical material in studies I and II comprises survey data from telephone interviews with a random sample of residents in the County of Stockholm aged between 18 and 84. In a number of countries there is a growing interest among social scientists and social policymakers in examining the types of support services that might be needed by people who provide informal care for older people and others. A further aim of the present dissertation is therefore to describe and analyse the carer support that is provided by municipalities and voluntary organizations in Sweden. The dissertation examines whether this support is aimed directly or indirectly at caregivers and discusses whether the Swedish government’s special financial investment in help for carers actually led to any changes in the support provided by municipalities and voluntary organisations. The main types of carer support offered by the municipalities were payment for care-giving, relief services and day care. The chief forms of carer support provided by the voluntary organizations were support groups, training groups, and a number of services aimed primarily at the elderly care recipients (Study III). Patterns of change in municipal carer support could be discerned fairly soon. The Swedish government’s special allocation to municipalities and voluntary organisations appears to have led to an increase in the number of municipalities providing direct support for carers, such as training, information material and professional caregiver consultants. On the other hand, only minor changes could be discerned in the pattern of carer support services provided by the voluntary organizations. This demonstrates stability and the relatively low impact that policy initiatives seem to have on voluntary organizations as providers (Study IV). In studies III and IV the empirical material consists of survey data from mail questionnaires sent to municipalities and voluntary organizations in the County of Stockholm. In the fields of social planning and social work there appears to be a need to clarify the aims of support services for informal carers. Should the support be direct or indirect? Should it be used to supplement or substitute caregivers? In this process of reappraisal it will be important to take the needs of both caregivers and care recipients into account when developing existing and new forms of support. How informal caregivers and care recipients interact with the care system as a whole is undeniably a fertile field for further research.
