As paisagens dunares são sistemas de elevado dinamismo, devido à proximidade do mar e à extrema mobilidade do substrato arenoso e prevê-se que venham a ser severamente afetadas pelas alterações ambientais globais. As dunas são depósitos de areia criados por processos eólicos e apresentam uma vegetação muito característica. Estes depósitos de areia em conjunto com a vegetação formam uma barreira essencial ao avanço do mar durante as marés altas de águas vivas e tempestades. Em Portugal, a degradação dos ecossistemas costeiros é muito preocupante. O problema das espécies exóticas invasoras agravou-se, aumentando a pressão sobre as plantas nativas. Embora este problema não seja o único motivo da degradação dos ecossistemas costeiros, este trabalho pretende divulgar as plantas dunares da zona costeira de Matosinhos, sensibilizar para a proteção e conservação das dunas e alertar para o facto de diversas plantas invasoras rapidamente colonizarem espaços abertos, pondo em causa e estabilidade dos ecossistemas costeiros. O conhecimento detalhado destes ecossistemas permitirá a aplicação de processos de vigilância e monitorização bem como o restauro ecológico de áreas dunares degradadas.

In view of the evident increase in the population group of people over 60 years old, the aging process has raised important discussions on social, political and economical planning that recommend that the increase in longevity must be followed by autonomy and well-being. Faced to these demands, the literature reports that physical activity is a key strategy to promote better living conditions for the elderly. Studies about personenvironment are making efforts to understand the socio physical environment role to encourage old people to make activities in many different environments. Among these, the urban public open space has been reported by many researches as a promising alternative in order to adopt a less sedentary life style. Based on these considerations, this study proposed to investigate the relationship between the social environment support elements and social interaction of seniors in public squares in the city of Natal, RN, using a multimethodological approach that included a experts panel, environmental characteristics analysis of 252 squares, case studies containing collective and individual interviews with elderly users and the spatial representation of their social interactions. The association between physical activities with the socialization practiced by them was identified as the main motivation for their presence in these places. The results indicate that the relationship between the socio-environmental characteristics (concept developed in this study) and the socio-spatial behaviors that include the spatial appropriation, spatial arrangements and interpersonal distances, helps to promote social interactions in carrying out activities, which, according to the assumptions Active Ageing Program, enable the maintenance of an active way of life, with important implications for health, wellness and quality of life in old age

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.

O objetivo deste estudo foi comparar a fusibilidade de ligas de Co-Cr-Mo-W (Remanium 2000), Ni-Cr (Durabond) e Co-Cr-Mo (Vera-PDI), incluídas em revestimentos à base de fosfato, sílica ou utilizando uma técnica mista. Uma rede de nylon quadrada (10 X 10 mm) com 100 espaços abertos serviu de modelo para construção de padrões de cera, que foram incluídos com revestimento à base de sílica, revestimento fosfatado e técnica mista (camada de revestimento fosfatado com 2 mm de espessura + revestimento à base de sílica). Quarenta e cinco espécimes (5 para cada condição experimental) foram fundidos sob chama de gás-oxigênio e a seguir jateados com óxido de alumínio. O número de segmentos fundidos completos foi contado para obter uma percentagem designada como "valor de fusibilidade", representando a precisão da liga em reproduzir os detalhes do molde. A análise estatística por meio de ANOVA a dois critérios e teste Tukey mostrou que, comparando-se as ligas, a Remanium 2000 teve fusibilidade estaticamente semelhante (p>0,05) à da Vera PDI e inferior à da liga Durabond (p<0,05). Considerando os resultados da técnica mista, a liga Remanium 2000 teve menor valor de fusibilidade (p<0,05) que as ligas Durabond e Vera PDI, que apresentaram valores estatisticamente semelhantes entre si (p>0,05). Concluindo, a fusibilidade da liga de Co-Cr-Mo-W (Remanium 2000) foi comparável à da liga de Co-Cr (Vera PDI) e inferior à da liga de Ni-Cr alloy (Durabond). À exceção da liga Remanium 2000, a técnica de inclusão mista aumentou consideravelmente a capacidade das ligas testadas de reproduzir os detalhes do molde, quando comparada à técnica de inclusão em revestimento fosfatado. A técnica de inclusão mista representa uma alternativa para melhorar a fusibilidade de ligas de metais básicos sem afetar a qualidade superficial das peças metálicas.

This research aims to study dimensions of urban life in the contemporaneous city. It is an effort to understand the functioning of the contemporary city as an artifact that somehow affects social relations. The study focuses on the limits and possibilities of urbanity in the city today, understanding urbanity as a set of factors that favor wealth, diversity and spontaneity of public life. The research aims to show that cities today tend to criate fragmented urban life into at least one of the three urbanity dimensions: spatial dimension, social and temporal dimension. The study involves the analysis of two public spaces in Fortaleza (Praça do Ferreira and the open urban public spaces of the Centro Cultural Dragão do Mar), using Space Syntax Analysis methods and for Post Occupancy Evaluation procedures. Research shows that temporal dimension of urbanity is limited in the public spaces studied. In Praça do Ferreira, spatial and social dimensions are present, but their effects are limited by the temporal dimension. The Dragão do Mar, on the other hand, the spatial and social dimensions of urban life are more limited and more concentrated in time

A construção da barragem do Alqueva causou várias transformações na paisagem ao nível sócioeconómico e ecológico. A submersão da antiga aldeia da Luz foi resultado desta construção, com consequente construção de uma nova aldeia. Um acontecimento que é marcante na história do Alqueva. O objetivo do trabalho de projeto é valorizar os espaços abertos públicos da nova aldeia e espaço envolvente. Esta estratégia assentou no reconhecimento e valorização dos sistemas ecológicos e culturais aí presentes, e na valorização do potencial turístico que lhe está associada. A metodologia do trabalho inclui uma análise das aldeias e realização de um inquérito à população (habitantes, residentes ocasionais e visitantes) com o fim de melhor responder aos seus anseios no presente. O trabalho culmina com a Proposta de Valorização de Espaço Aberto Público para a aldeia da Luz e espaço próximo envolvente e com o Plano de Estrutura Ecológica e Cultural (urbana e rural); Aldeia da Luz: towards the open public spaces valorization ABSTRACT: The construction of the Alqueva dam has caused several landscape transformations, in the socioeconomical, ecological matter. The submersion of the old Luz village was a direct result of this construction, with the consequent construction of a new Luz village. An event, which is remarkable in the Alqueva history. The project work objective is to value the public open spaces of the new village and its surrounding space. This strategy settled on the recognition and appreciation of the existing ecological and cultural systems, and in the touristic potential that is associated with it. The work methodology includes analysis of the villages and a survey fulfilment targeting the population (habitants, occasional residents and visitors) with the intent of better answering their current desires. The work culminates with the Public Open Space Appreciation Proposal for the Luz village and nearby surrounding space, and with the Ecological and Cultural Structures Plan (urban and rural).

This research presents a study investigating the correlation between the environmental-physycal charcateristics of cities and the formation of its micro-climates. The study was conducted in the central area of Fortaleza characterized as a stable and consolidated area, where the city originated and currently faces serious problems in its urban dynamics. The points of measurements were determined by the elaboration and analysis of topography maps, height of buildings, land use, type of surface coating and vegetation, following the methodology of Katzschner (1997). A zoning map was then determined, according to common morphological characteristics of the 12 measurement points, which were based on a set of Romero s (2001) bioclimatic criteria. Air measurements, temperature, humidity, intensity and direction of winds were made in transect form in two different circuits in the study area, with six points of data collection in each area, in three different times: 6:00 am, 1:00pm and 7:00pm, during two periods of the year: August 2008 and March 2009. The results verified the influence of different environmental-physical types in the behavior of the climatic variables that were collected. A verticalização tão condenada em algumas situações se bem equilibrada e controlada pode reduzir as temperaturas do ar através do sombreamento dos espaços urbanos e possibilidade de maior permeabilidade a ventilação natural. The highest average air temperature and lower humidity were recorded at the point I at all times. This situation may have been in result of the high density, poor vegetation and extended paving of the ground. According to the results, it s clear the positive influence vegetation has on easing air temperature. Another indicator observed that areas with a greater variation in building heights tend to present decreased average air temperature. High rise structure, planned in accordance to urban air quality parameters, can reduce air temperatures by the shading of urban spaces and the possibility of greater penetration of natural ventilation
