Lugares de fronteira: as tascas localizadas nas portas da muralha Fernandina de Évora

Esta dissertação de mestrado tem por objecto de estudo o conjunto das tascas localizadas nas portas da Muralha Fernandina de Évora. Praticamente desaparecidos espaços ainda íntegros, pode-se considerar que estas construções integram uma rede de estabelecimentos composta por estruturas militares, religiosas, de lazer e de carácter colectivo, que se encontram associadas e caracterizam as portas medievais de Évora. O objectivo desta investigação é o estudo urbanístico e arquitectónico das portas urbanas, e o modo como os estabelecimentos de venda de bebida configuraram as diversas narrativas urbanas a partir de diferentes orientações políticas ao longo dos tempos. O caso de Évora é tomado como base de trabalho por ser legível ainda uma imagem de conjunto, a partir de vestígios, exemplares minimamente conservados, fontes históricas, impressas e fotográficas. A articulação urbana típica e recorrente, na relação directa tasca-porta, pode-se encontrar noutras cidades alentejanas, e nas cidades amuralhadas em geral; PLACES OF FRONTIER: THE TAVERNS LOCATED IN THE GATES OF EVORA'S FERNANDINA WALL ABSTRACT: This dissertation has as subject the study of the taverns located in the gates of Évora's Fernandina Wall. Despite the almost disappearance of intact spaces, it can be considered that these buildings are part of a network of institutions composed of various structures such as military, religious, recreational and collective character, which are associated and feature the ancient medieval gates of Évora. The aim of this investigation is the urban and architectural study of the urban gates, and how the beverage outlets have represented the various urban narratives from different political orientations over time. The case of Évora is the base of work by being a readable group, from traces, minimally preserved specimens, historical, printed and photographic sources. The typical and recurrent urban articulation, in a direct relation tavern-gate, can be seen in other Alentejo towns, and walled cities in general.

Viabilidade do uso agrícola de resíduo da construção civil e da indústria cerâmica: atributos químicos.

O setor de construção civil enfrenta sérios problemas quanto à disposição de resíduos, uma vez que gera grandes quantidades ao longo do processo de execução das obras ou devido ao desmonte de construções já existentes. A disposição inadequada desses resíduos pode provocar sérios danos ambientais, tais como degradação do solo e recursos hídricos. Uma opção interessante pode ser seu uso agrícola, entretanto existem poucos estudos sobre o tema. Assim, o presente estudo visou caracterizar resíduos da construção civil e avaliar seu efeito sobre alguns atributos do solo. Para tal, foram realizadas análises de pH, teor de macro e micronutrientes e de elementos potencialmente tóxicos. Os resultados indicaram que os resíduos não poderiam ser utilizados como fonte de nutrientes e que também não apresentavam limitações quanto à presença de elementos potencialmente tóxicos. Os altos valores de pH encontrados indicaram potencial dos resíduos em alcalinizar do solo, o que foi confirmado no ensaio em vasos. Também se constatou que os resíduos provocaram aumento da CTC. Assim, concluiu-se que é viável utilizar esses resíduos da construção civil em solos agrícolas, embora mais avaliações ainda devam ser realizadas.

Avaliação da potencialidade dos resíduos de gesso de revestimento incorporados em formulações de massas cerâmicas

In building, during the implementation process of major or even minor works, there is a considerable waste of plaster in the steps of coating, making it is a negative factor because of the loss of these processes constructive remains incorporated into buildings, as component, whose final dimensions are higher than those projected. Another negative factor is the disposal of waste gypsum in inappropriate places, thus contributing to the degradation of environmental quality, due to the leaching of this waste and may trigger the formation of sulfuric acid. Therefore, based on this picture, processing and reuse of waste coating, combined with the ceramics industry, which is a strong potential in the reuse of certain types of waste, promote mutual benefits. Thus the overall objective of this work is to conduct a search with scientific and technological aspects, to determine the effect of the incorporation of the residue of plaster for coating, from the building, the formulation of bodies for red ceramic. The residue of plaster coating was collected and characterized. They were also selected raw materials of two ceramic poles of the state of Rio Grande do Norte and formulations have been made with the intention of obtaining those with the best physical and mechanical properties, the residue was added the percentage of 5%, 10%, 15%, 20%, 25% and 30%, in the best formulation of ceramic industry 1 and, according the properties analyses, 5%, 10% and 15% as the best results of ceramic industry 2. The samples were sintered at temperatures of 850 ºC, 950 °C and 1050 °C, the heating rate of 5 ºC / min with isotherm of two hours. They were submitted to testing technology, such as lineal shrinkage, water absorption, apparent porosity, apparent density and bending resistence. The residue incorporation best results in the formulations of mass in red ceramic, were observed between the temperatures of 850 ºC and 950 ºC, in those formulations that have illite clays and medium plastic in their composition, in the range of 0% to 15% residue incorporated

Casa de embalagem de placas planas recicladas e tetra pak®: alternativa econômica e viável para a produção integrada de morango.

De acordo com Brasil (1997a, 1997b), as áreas de manipulação de alimento, como as Casas de embalagens de morango, devem atender a uma série de critérios. Os pisos devem ser de material resistente ao trânsito, impermeáveis, laváveis, antiderrapantes, não possuírem frestas e serem fáceis de limpar ou desinfetar. As superfícieis devem ser de material de fácil higienização. Atualmente, na região produtora de morango de Atibaia e Jarinu (SP), grande parte das Casas de embalagem convencionais são precárias, feitas somente de uma estrutura de madeira sem revestimento, coberta por folhas de Tetra Pak® e chão de terra-batida. Essas Casas não oferecem as condições mínimas de higiene previstas pelas Portarias mencionadas nem nas Normas Técnicas Específicas da Produção Integrada de Morango - NTE-PIMo (BRASIL, 2008), que estão sendo adotadas por um grupo de produtores da região. Devido ao fato do chão não ser lavável e as madeiras não receberem tratamento, as construções inadequadas podem se transformar em locais de propagação de patógenos, colocando em risco a segurança do morango embalado. No entanto, a falta de recursos financeiros dos pequenos produtores limita a compra de materiais ideais e de alto custo (aço inoxidável, por exemplo), a serem utilizados na construção. O objetivo deste trabalho é apresentar uma proposta de construção de uma Casa de embalagem simples, economicamente viável e que atenda minimamente às normas e portarias mencionadas, usando materiais de baixo custo e disponíveis na região.

A influência de decisões arquitetônicas na eficiência energética do Campus vol. 1/UFRN

Building design is an effective way to achieve HVAC energy consumption reduction. However, this potentiality is often neglected by architects due to the lack of references to support design decisions. This works intends to propose architectural design guidelines for energy efficiency and thermal performance of Campus/UFRN buildings. These guidelines are based on computer simulations results using the software DesignBuilder. The definition of simulation models has begun with envelope variables, partially done after a field study of thirteen buildings at UFRN/Campus. This field study indicated some basic envelope patterns that were applied in simulation models. Occupation variables were identified with temperature and energy consumption monitoring procedures and a verification of illumination and equipment power, both developed at the Campus/UFRN administration building. Three simulation models were proposed according to different design phases and decisions. The first model represents early design decisions, simulating the combination of different types of geometry with three levels of envelope thermal performance. The second model, still as a part of early design phase, analyses thermal changes between circulation halls lateral and central and office rooms, as well as the heat fluxes and monthly temperatures in each circulation hall. The third model analyses the influence of middle-design and detail design decisions on energy consumption and thermal performance. In this model, different solutions of roofs, shading devices, walls and external colors were simulated. The results of all simulation models suggest a high influence of thermal loads due to the incidence of solar radiation on windows and surfaces, which highlights the importance of window shading devices, office room orientation and absorptance of roof and walls surfaces

A assistência técnica nos habitats do MST e o papel do arquiteto e urbanista

This dissertation is about Architect and town planner inserts in the technical support of the Rural establishment and of the possibilities of changes in their habitat. It also looks for its participation through the production of those spaces with or without its performance through two references cases, in Rio Grande do Norte , one called settlement Eldorado de Carajás and another one called Maria da Paz. At first the process represents the model that was adopted systematically by Incra until the middle of the year 2000 with the sub-contracting of their construction work through small companies. These standardized projects which are executed without registration in the system CONFEA/CREA without demand of professional authorship and of technical responsibility of the work. But the process taken place at Maria da Paz s area was configured as one of the first initiatives that stopped with those practices. Consolidated through a partnership among UFRN MST and INCRA/RN, the Architect s technical support and town planner brought new technician-scientific organization and execution of the soil parcels and its habitat. The participation of UFRN was done through a group of studies in land reform and Habitat (GERAH) being this author and coordinator of the methodological proposal, based on the regressive-progressive method and in the inclusion of the conflict as responsible of the ruptures and transductions both done by Henry Léfèbvre and in the research action approached by Carlos Brandão. Therefore it included the process of social learning and collective production of new knowledge and attitudes in relation to the environment in the process called as attended self management in spite of the transformations happened with this new agent s participation. The people re-located to the new areas that got involved in the process and finished their constructions reelaborating the daily practice of the collective effort passed to the self management without technical support. Years later the implantation of those two experiences our research verified that there is a positive image concerning the Architect and town planner, related, most of all to the conception of the activities, orientation and execution of constructions projects and of acceptance of those professionals to the processes of implementation of the Habitats of the Rural establishments. This dissertation analyses this form of performance, from and beyond these images trying to find the professional, specificities or methodological in such a way to demonstrate the importance of its insertion in the formulation and attendance of the more of 100.000 habitats of Rural establishments of the land reform of the country that correspond to most of the housing social interest in the country side

Fachada flexível para casa padronizada em condomínios

The employment of flexibility in the design of façades makes them adaptable to adverse weather conditions, resulting in both minimization of environmental discomfort and improvement of energy efficiency. The present study highlights the potential of flexible façades as a resource to reduce rigidity and form repetition, which are usually employed in condominiums of standardized houses; as such, the work presented herein contributes to field of study of architectural projects strategies for adapting and integrating buildings within the local climate context. Two façade options were designed using as reference the bionics and the kinetics, as well as their applications to architectural constructions. This resulted in two lightweight and dynamic structures, which cater to constraints of comfort through combinations of movements, which control the impact of solar radiation and of cooling in the environment. The efficacy and technical functionality of the façades were tested with comfort analysis and graphic computation software, as well as with physical models. Thus, the current research contributes to the improvement of architectural solutions aimed at using passive energy strategies in order to offer both better quality for the users and for the sustainability of the planet
