Ventilação e prescrições urbanísticas: uma aplicação simulada para a Orla da Praia do Meio em Natal/RN

This work analyses a study on natural ventilation and its relation to the urban legislation versus the building types in an urban fraction of coastal area of Praia do Meio in the city of Natal/RN, approaching the type or types of land use most appropriate to this limited urban fraction. The objective of this study is to analyse the effects of the present legislation as well as the types of buildings in this area on the natural ventilation. This urban fraction was selected because it is one of the sites from where the wind flows into the city of Natal. This research is based on the hypothesis stating that the reduction on the porosity of the urban soil (decrease in the set back/boundary clearance), and an increase in the form (height of the buildings) rise the level of the ventilation gradient, consequently causing a reduction on the wind speed at the lowest part of the buildings. Three-dimensional computational models were used to produce the modes of occupation allowed in the urban fraction within the area under study. A Computational Fluid Dynamics (CFD) software was also used to analyse the modes of land occupation. Following simulation, a statistical assessment was carried out for validation of the hypothesis. It was concluded that the reduction in the soil porosity as a consequence of the rates that defined the minimum boundary clearance between the building and the boundary of the plot (and consequently the set back), as well as the increase in the building form (height of the buildings) caused a reduction in the wind speed, thus creating heat islands

Ventilação e prescrições urbanísticas: uma aplicação simulada no bairro de Petrópolis em Natal/RN

The present work studies the natural ventilation and its relationship with the urban standards, which establishes the form of occupation and use of the land in our cities. The method simulates the application of the urban standards of the City Master Plan over the last three years. The simulation takes place in the District of Petrópolis, in the city of Natal , Brazil and analyses the effects of the standards of natural ventilation. The formulated hypothesis states that the reductions in the urban spaces between buildings rises up the vertical profile of ventilation, reducing, therefore, the velocity of the wind at the lower levels of the buildings. To develop the study, occupation models were built, using computerized, three-dimensional models. These occupation models were analyzed using the CFD (Computational Fluid Dynamics) code. The conclusion is that the more we reduce the urban space between buildings, the more we reduce the wind speed in constructed areas, increasing, therefore, the possibility to generate heat islands

Da poética das lágrimas a uma poética do riso: de Aristóteles ao One-man show

Since the 1970s, the world observes the fragmentation, hybridity, plurality and miscegenation that are taking over the scenic arts. The contemporary poetry feels free of the classical rules; theater no longer obeys the requirements of the poetic "manuals"; the rigid boundaries between genres disappears; artists cease to represent to the public to talk with him. In the last decades of twentieth century and in the twenty-first century, emerges the laughable phenomenon of One-man Show in the brazilian scene, object of this research, as a result of this evolution of the performing arts. It is a form of theater that emerged in the brazilian context, snatching public attention in alternative spaces, theaters and, as it should be, also on the Internet, often confused with the Stand-up Comedy. It is necessary a research that delimitate and pursue to identify the essential characteristics of the brazilian One- Man Show, not only by the absence of theoretical references concerning this, but also to understand some aspects of the brazilian scene and the situation of laughter and comedy in it. In the first chapter, a discussion about comedy and laughter in classical antiquity is presented, using the writings of Plato and Aristotle as a starting point; in the second, some of the main classical theories of laughter are reviewed, attempting to identify the general characteristics that enable to understand the construction of the comedy; the third chapter generally dicusses about the moment of the brazilian theatrical scene in which emerges the One-man Show; and in the fourth chapter, there is an explanation about this phenomenon and a description of the practical exercise titled Experimento One-person Show: Damas
