The state of Rio Grande do Norte has been undergoing transformations in their territory, they are promoted by the installation of new infrastructure equipment, which in turn cause changes in the dynamic spatial and social hour set, causing new arrangements and new dynamics between cities. The overall goal of the research is to understand, at present, the urban network of the Rio Grande do Norte, from the centers of territory management. The picture presented in the paper reveals a network of cities that has gained a material basis urban, with the installation of new objects macro state structures (roads, ports, wind farms, banks, pipelines, internet access) that enable a relationship more intense between the urban centers of the state and other cities in the world, that the current structure characteristic of the urban network, its global nature, since the possibility of relations between the centers is greater. Such a relationship is indeed possible because the characteristics of the current historical period, with the high density of the tripod technique, science and information controlled by the market. In Rio Grande do Norte intentionality of the new arrangement that is configured is not other but meet market demands

Taking into account the Environmental Restorative Theory (ERT) , created by Fre derick Law Olmsted in mid XIX ce ntury , according which, urban parks can contribute to solve problems arisen from crowding , particularly urban stress, we analize how the ERT arrived at XXI century, having as approach the evaluation of New York Central Park (CP). Considering that the CP and the cinema were born around at the same, we question if the North American cinema produced between 1960 and 2013 show the ideals, which engendered the CP. By answering this question we defend the hypothesis that, even though has existed adjusts and modificati ons in the CP plan through time, it kept reasonably faithful to the ERT premises, propitiating to the XX and XXI centuries cinema identify and bring forth the presence of the Olmsted’s Ideals in the present days. The thesis main objective was nonetheless u nderstand similarities and/or differences between the XIX century ideals (that gave birth to CP) and the way the cinema represents the present uses of the place, taking into account that the Olmstedian ERT proposal have survived to the context changes (soc ial, economic, political and cultural). Methodologically , we drew upon bibliographical and documental analysis to build the first chapters and to the cinema as analytical lenses to investigate the ERT. The results point that although the CP plan has kept r elatively intact and faithful to the ERT – with the presence of natural elements in the films (notably vegetation and water) – many of contemporary behaviors were not foreseen previously, especially in relation to sports practice, the massive feminine pres ence, as well as criminality.

An important problem faced by the oil industry is to distribute multiple oil products through pipelines. Distribution is done in a network composed of refineries (source nodes), storage parks (intermediate nodes), and terminals (demand nodes) interconnected by a set of pipelines transporting oil and derivatives between adjacent areas. Constraints related to storage limits, delivery time, sources availability, sending and receiving limits, among others, must be satisfied. Some researchers deal with this problem under a discrete viewpoint in which the flow in the network is seen as batches sending. Usually, there is no separation device between batches of different products and the losses due to interfaces may be significant. Minimizing delivery time is a typical objective adopted by engineers when scheduling products sending in pipeline networks. However, costs incurred due to losses in interfaces cannot be disregarded. The cost also depends on pumping expenses, which are mostly due to the electricity cost. Since industrial electricity tariff varies over the day, pumping at different time periods have different cost. This work presents an experimental investigation of computational methods designed to deal with the problem of distributing oil derivatives in networks considering three minimization objectives simultaneously: delivery time, losses due to interfaces and electricity cost. The problem is NP-hard and is addressed with hybrid evolutionary algorithms. Hybridizations are mainly focused on Transgenetic Algorithms and classical multi-objective evolutionary algorithm architectures such as MOEA/D, NSGA2 and SPEA2. Three architectures named MOTA/D, NSTA and SPETA are applied to the problem. An experimental study compares the algorithms on thirty test cases. To analyse the results obtained with the algorithms Pareto-compliant quality indicators are used and the significance of the results evaluated with non-parametric statistical tests.

Through participant observation, held in the administrative region east of Natal / RN, this research aimed to understand about the daily life of men and women living on the streets in the city. How they relate to the space where they live? In this relationship, which uses and survival strategies triggered by this social segment? These were some of the questions that guided this research, in order to highlight the specificities of this way of life and the possible consequences that such a situation could reverberate. In this sense, there was an effort to keep up with people on the streets, their itineraries and seize their narratives. Along the search path - which took place intermittently between the years 2011-2015 - attended spaces of occupation and traffic of this population group in the street, as well as insert me and got involved in events, forums, seminars, meetings and subject of joints on the streets as a political movement (MNPR / RN). They are considered in this study as people on the street to those who occupy the street as their main space of survival and ordering of daily life: in the streets sleep, feed themselves, meet the physiological and hygienic needs, and is where draw sustenance. The street is taken in this research in its broadest sense, including all possible places relatively protected from the cold, rain and exposure to violence, thus includes both open and public spaces: as squares and parks; but also closed and private places: hostels, abandoned warehouses, prisons, etc. It was observed that in none of these spaces guys on the street are established in a fixed manner, in contrast, they experience the roaming, which in part is due to urban systems - which tends to stigmatize them and delete them places - and the very need to survive, because while living in the street differentiated practices are triggered, and these differ from the dominant mode of sedentary life.

Offshore wind power emits low amounts of gases, is renewable and has better performance than onshore due to its greater stability and higher wind power density, less visual and noise impact, among others. Brazil has a high capacity of generation, but has not yet developed any offshore projects. High costs are a strong impediment. This study is an effort towards pricing offshore resources through Livelized Cost of Energy - LCOE, which represents the minimum return to cover the costs of development, production and maintenance of a wind project. Initially LCOE was calculated for all Brazilian onshore wind farms listed at Bloomberg New Energy Finance R○, accounting for 71 farms. Then hypothetical offshore wind farms were created from the onshore farms, tripling the cost of generation, which is consistent with the literature, and estimating the offshore energy for two locations off the Brazilian coast using satellite data extracted from National Oceanic and Atmospheric Administration. The results demonstrate that offshore resources have the potential to significantly reduce the energy price due to the better performance of the wind at sea

This body of work discusses the gender meanings associated with cowboys while endorsing contemporary rodeos in Rio Grande do Norte as a recreational sport and a form of ludic expression. As a result, this research has focused on rodeo practices, aiming to understand the different aspects emphasizing masculinity: these associations being constructed through relationships, contexts and the competitiveness between participants. These gender meanings hinge on the desire for a wining performance and on the behaviour exhibited among cowboys outside the competitive ring in specific social settings such as parties and recreational time. The latter were the focus of the ethnographic research; direct observation and semistructured interviews with cowboys in rodeo stadiums were also used. Through qualitative analysis of the collected data, it was revealed that historically and socially different trajectories do not immediately cause a gender crisis in cowboys, but the assignment of new significance by the social acts in each historical context. However, the presence of cowboys leads to other models of masculinity configured by expressions and the insertion of new personas, not coming directly from field activities, but imbued by the symbolic elements of the cowboy persona, constructed throughout history

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

Owing to na intense process of urban development, urban uneasiness and discomfort in the daily life of populations have nowadays, especially in the big cities, become increasingly ordinary issues. Population density, degeneration of central areas and pollution are some of the environmental stressors the urban man is subjected to. The existence of open areas in the urban network contributes to a better movement of the air and transforms salubrity conditions. Yet, it has been noticed that parks and squares are disappearing from the heart of the city districts. In their place there are either unused plots of land where garbage has been dumped or nearly all-paved squares with meager or no vegetation at all. Such areas, when handled properly, play an important role in the city because in addition to being zones for rendering a mild climate they perform social, cultural and hygienic functions. Aiming at demonstrating that proper handling of green areas can favorably influence the local microclimate, we have attempted to develop analysis from the point of view of bioclimatizing attributes of urban form and their relationship to the local microclimate found in the eight open areas located in the Ponta Negra Housing Complex in the city of Natal/RN

The purpose of this dissertation is to analyse the importance of the huts of Praia do Futuro to their users and to the city of Fortaleza in Ceará through the comprehension of relations between morphological categories - in urban and edified contexts - of the establishments and their use patterns. This place is one of the main recreation and leisure areas of the city, formed by six kilometres of waterfront, corresponding to a differentiated area through the coast. This space has beach huts with varied profiles: while some more simple huts persist, great complexes are being developed, building even water parks on the beach area. This study analyses relations between:i) spatial configuration (in geometric and mainly topological terms) based on the Social Logic of Space; ii) edified typology (analysing capacity, landscap treatment and program of the huts); and iii) use and environmental perception of the beach by its frequenters. There are consistent relations between the type of hut and their localization in the urban grid, of which were identified groups with different patterns: segregated (north, central and south) and integrated (north: more integrated. and south: less integrated). Such relations also reflect, in varied patterns of use and environmental perception. In spite of their strong economy, the beach huts find themselves in a fragile legal situation because they occupy the beach area, so that this study may come to assist the decision-making for the future of the region. For a sustainable development of the area by those responsible and managers it is necessary to evaluate the cultural importance of the huts at Praia do Futuro, understanding their occupation and uses.
