In the midst of growing preservationist awareness, regarding methods of architectural intervention of buildings with a recognized heritage value, there are numerous approaches on how the original heritage value can be protected. However, can these intervention projects be differentiated? Is it possible to identify how they differ (if in fact they do) from an architectural project not related to preservation? Although there are numerous theoretical studies regarding methods utilized in architectonical projects, there appear to be a lack of studies focused on an architectural intervention exclusively focused on areas or edifications that have a recognized heritage value, thereby requiring a reflection on which methodological procedures in an architectonical project serve the purpose of the preservation of the historical aspects. This discussion is of even greater importance because, at the national level, some recent discussions on this type of architectural design seem arbitrary and lack methodological rigor. Therefore, this research attempts to focus equally on the theoretical-methodological practices of preservation as well as the architectural project methods. In an attempt to address these aspects, the focus of this research centers on the case studies of the intervention projects of the maritime passenger terminal of Natal (Terminal Marítimo de Passageriros de Natal), the old government hall (Palacio do Governo - EDTAM) and the old central hotel (Hotel Central) which are situated in the area known as the historic downtown of the city of Natal, within the federal heritage protection polygon. The analyses of these is intended to identify what methodological procedures were recorded in the final product (in the graphical representation of the architectural design and other documents) delivered to IPHAN / RN, the body responsible for review and approval of these architectural projects, noting whether such procedures appear, in some way, in the final product, and if an understanding of the complexity of preservation is evident. The analyses of these projects corroborate the hypothesis that there are unique characteristics, which must be addressed in the intervention project for preservation when compared to new project design. The main characteristic to be addressed is related to the very nature of the project. It is inherent in the dialectical relationship between the need to preserve (the identified heritage values) and the need to modernize (making adaptations to contemporary life). This relationship, denominated in this dissertation as "radical restraint", must, or at least should, guide the actions in the project as well as the technical analyses of the preservationist organization. However, this radical restriction appears more evident in the guidelines put forth by legislators than in the decisions of designers. These legislators require the presentation of documents, aimed at identifying and contextualizing intervention (Ordinance No. 420 of December 22, 2010), that grant (or should grant) assistance in the decision making process. It was evident in the analyses of these documents that there existed a disconnect between the documents produced and the decisions made in the project. This fact can be seen in the total absence of dialogue about theoretical-methodological preservationist principles, which, in our view, is an essential element of the methodological procedures of the intervention project needed to guide the legislative and project design discussions.

Standardization and sustainability: these two apparently antagonistic words find the challenge of uniting in a flexible architectonic proposal. This was the idea that motivated the proposal of this assignment, whose appearing is bound up with the necessity of thinking about standardized spaces that attend on functional criterias and environmental sustainability, in reply to an existing real demand. The assignment consists of an architectonic proposal for a flexible standard of a Basic Unit of Health for the bioclimatic zone 7 of RN (UBS RN-7), with emphasis in the environmental sustainability. The project contemplates innumerable involved variables, such as: obedience to the current law of the Health Ministry for the UBSs; formal/aesthetic aspects; criterias of expansiveness of the UBS I for the UBS II; relative aspects to the constructive rationality and, mainly, sustainability aspects. With the intention to unite the variables and, also, glimpsing a proposal that could reach a good functional performance, aesthetic, of environment comfort and energetic efficiency, it was also necessary to consider concepts about the flexibility of the envelopment. The elaboration of the architecture first draft was based on bibliographical research, conceptual studies and references, elaboration of the architectonic program and the draft development for the UBS port I and the UBS port II. To the end, an implantation data sheet for the project is proposed for the UBS standard project, where strategies of thermal isolation, shadowing and thermal inertia are adopted and combined to three possible types of lot, resulting in 24 possibilities of implantation

Despite the importance of coral reefs to humanity, these environments have been threatened throughout the world. Several factors contribute to the degradation of these ecosystems. The Maracajaú Reef Complex, in Rio Grande do Norte state is part of the Coral Reefs Environment Preservation Area in northeastern Brazil. This area has been receiving an increasing influx of tourism and the integrity of the local reefs is a matter of concern. In this study, the reef macroalgae communities were studied and compared within two areas distinguished by the presence or absence of tourism activities. Two sample sites were chosen: the first one, where diving activities are intense; and the other, where these practices do not occur. Samples were collected at both sites within a quadrate of 625 cm2 of area randomly thrown 5 times along a 10 meters transect line. Richness, Shannon-Hill diversity and Simpson dominance indices were determined based on biomass data. Similarity between sites was analyzed with Bray-Curtis similarity and distance index. Fifty-eight macroalgae species were observed, including 7 Chlorophyta, 13 Phaeophyta and 38 Rhodophyta. In the non-disturbed site, 49 species were found, while at the disturbed site, there were 42 species. Dictyotaceae and Corallinaceae were the most representative families at the non-disturbed site, and Rhodomelaceae and Dictyotaceae at the disturbed site. The non-disturbed site presented a higher biomass and the greatest richness and diversity indices. In the disturbed site the dominance index was greater and Caulerpa racemosa was the dominant species. The dendogram based on similarity index showed two major clusters, and an isolated element at the center that corresponds to a sample from the disturbed site. In the first cluster, samples from the non-impacted site were predominant and fleshy brown algae were more conspicuous. The second cluster was composed primarily of samples from the impacted site, where C. racemosa and red filamentous and erect calcareous algae associations (turf forming) were observed covering large extensions. These associations are represented by groups of algae adapted to environments where disturbances are frequent. They can grow rapidly on substrate where benthic community was removed and do not allow the establishment of other species. The results of the present study show that tourism activity is an impacting factor that has been causing shifts in macroalgae communities in the Maracajaú Reef Complex

This study evaluated the effect of indole-3-acetic acid (IAA) in the activation of goats preantral follicles (FOPA). Were used four pairs of ovaries of adult mixed breed goats. Each ovarian pair was divided into 23 fragments. One fragment was fixed for histology and other fragment was using to follicular isolation procedure. The remaining fragments were cultured in 1.0 ml of Minimum Essential Medium (MEM) or MEM supplemented with IAA at concentrations of 10, 40, 100, 500 or 1000 ng/mL. The in vitro culture was performed at 39°C in incubator with 5% CO2 for 1, 3 and 5 days. After in vitro culture was evaluated histological integrity and viability of FOPA. The addition of 100 ng/ml of IAA to MEM showed a significant increase in follicles transition in the third day of in vitro culture, characterizing follicular activation. Moreover, this concentration was obtained maintaining the histological integrity of PAF by the fifth day of in vitro culture. The viability test confirmed the results of histology. Thus, we conclude that IAA can promote the activation of goats FOPA

Liofilização é um método alternativo de preservação de espermatozóide, com vantagens sobre o criopreservado pelo baixo custo de armazenamento, facilidade no transporte pela não necessidade de containers e baixas taxas de contaminação. Esse estudo foi realizado no intuito e testar a eficácia de 5 açúcares na proteção do material cromossômico (DNA) de espermatozoides humanos liofilizados após reidratação. Para isso foram utilizados espermatozoides de indivíduos classificados como normozooespérmicos segundo OMS. Em eppendorfs foram colocados 1ml de sêmen que foram diluídos (1:1) em 1 ml de solução de Glicose, Lactose, Maltose, Manitol e Sorbitol, separadamente, nas concentrações 0.2M, 0.4M, 0.5M e 0.6M. Essas amostras foram analisadas em duas fases a primeira após congelamento observando a porcentagem de células com danos de membrana e outra análise após a liofilização, utilizando o Teste Cometa para detectar as taxas de fragmentação de DNA dos espermatozoides recuperadas após reidratação. O processo de liofilização de espermatozoides não foi capaz de recuperar a motilidade dos mesmos, mas foi capaz de manter 62.30 ± 13.76% de membrana plasmática intacta na presença de 0.6M manitol. As substâncias que melhor preservaram o DNA dessas células foram 0.2 lactose, 0.2M e 0.6M manitol e sorbitol, com apenas 4% de danos ao DNA. Esses resultados sugerem uma boa proteção ao DNA de espermatozoides humanos liofilizados, mas ainda requer testes adicionais para avaliar a fertilização e estudos que garantam a viabilidade da prole

The purpose of this study was to evaluate the effectiveness during a twelve-month period, of resin-modified glass ionomer (Vitremer@) used as fissure sealants compared to supervised teeth brushing in the prevention of oclusal caries in permarient molars of pubIlc school children from 5 to 7 years of age. A total of 91 children participated in the study, being randomly divided up into three groups of investigation: group with sealant (n=31), group of supervised brushing (m=30), and control gorup (n=30). After 12 months, a total of 28.5% of tosses in the sample of 26 children was registered, and although there wasn t a significant diference between these losses and the groups studles (p = 0.6355), there was a considerable reduction in the sample. The results showed that none of the independentIy studied variables (present caries experience, biofilm, bleeding, sealant retention, position of the tooth in the arch, and sex) interfered in the final results, and that there was no significant difference between applying the sealant in question, perfornling supervised dental brushing, or not intervening at alI (p=0.542). These results could have been a consequence of the limitations found alI through the study, especially relating to the losses occurred because of school evasion, transfer, or because of the accident in the Marise Paiva Municipal School, Keeping students away for approximately one semester, so tht a new reseach had to be developed sos as to better clarify the effects among the treatments done there

The purpose of this paper is to identify and analyze the main environmental impacts taking place in the permanent preservation areas located in the Ceará-Mirim River estuary/RN and its surrounding areas. For that, the study was divided in two chapters, structured in the shape of a scientific paper. The first is a theoretical proposition on the occupation of the APPs in light of the discussion of the geographic space and the sustainability of the development, where a bibliographical review was made emphasizing the production of the geographic space, the sustainability of the development and the permanent preservation areas. In the second chapter, from a systemic approach, geoprocessing techniques and the adaptation of the Pressure-State- Response Indicators System were used, the latter being developed by the Organization for Economic Co-operation and Development OECD. Therefore, from the methodological approaches used, it's been observed that the use of permanent preservation areas for purposes other than those determined in the legislation and, mainly guided by capitalist interests, leads to the environmental degradation of these areas, fact which has been confirmed in the empiric study conducted in the second chapter, where it was possible to identify a series of environmental impacts such as: deforestation of mangrove and riparian vegetation for carciniculture implantation, the devastation of dune areas caused by the urban expansion in the coastal stretch and siltation of fluvial channel

The vast hidric wealth of Brazil gets its watersheds more susceptible to impacts that compromise the water quality, affecting the ecosystem stability of aquatic environments. The decrease in the quality of water resources also results in a decrease of its multiple uses, especially in tourist areas of the coast, where the continuous flow of people to these sites increases even further the probability of inappropriate behavior of both tourists and local residents. Studies regarding the microbiological communities are still scarce, especially on the free-living protozoa that play unique roles in the food chain of aquatic ecosystems. Due to the large role played by this group of microorganisms in aquatic environments, the present study aimed at identifying the genus and species of free-living protozoa present in two sections of the Pium River, east coast of Rio Grande do Norte, making an association between the its occurrence and trophic conditions of the environment in which they are, also checking the bioindicator capacity of these organisms in water quality. It also aimed to conduct a survey with students to identify the main difficulties regarding the knowledge of free-living protozoa and hydric transmission diseases in two public schools near the river studied in the Pium district, county of Parnamirim. The survey was analyzed by means of questionnaires at both schools. Students identified several activities developed Pium river, highlighting its multifunctionality and importance to the region. A total of 76 taxa of free-living protozoa was recorded, of these, 33 were ciliates, 19 flagellates and 24 sarcodia. The spatial and temporal patterns of these organisms to both points studied revealed the bioindicator potentiality of some effective species identified. However, knowledge about the free-living protozoa proved quite lagged, presenting misconceptions that show them as pathogenic organisms exclusively, totally disregarding their ecological role. In order to remedy the flaws existing in students in relation to the functional role of protozoa, workshops were planned on these microorganisms while also addressing issues related to hydric transmission diseases through lectures, recreational activities and interactive presentations. These practical activities of Science Education had the goal of bringing students the context of local water resources, aiming to promote a greater clarification regarding of the functional role of free-living protozoa in aquatic environments

This study was conducted in the city of João Pessoa, Paraíba mesoregion Forest. Having to analyze how does the appreciation of the architectural heritage to the visitor and pessoense Capital Paraiba, taking into account the narratives of João Pessoa, and practitioners of foreign tourists of cultural tourism. This research builds on a theoretical foundation on concepts of landscape and place. Was taken as a foundation to Cultural Geography. The research in question is justified by embarking on Geography and Heritage and cast a glance on the geographical cultural landscape, trying to unravel the symbols assigned to the ancient architectural examples, meaning that interfere with power relationships that cross generations, constructing and deconstructing identities, is dispersed or integrating cultures, creating cultural groups and social conflict. It is concluded that the geographical area derives from a number of factors, among them the culture and this in turn will shaping the landscape, reflecting the abstract over the concrete architecture of the oldest to the most current, turning from the material to the immaterial in World Heritage Site

In recent years, as part of the expansion process of its activities, the Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte – IFRN (Federal Institute for Education, Science and Technology of the State of Rio Grande do Norte – IFRN) detected the need to hire more employees for the institution. This expansion process, a policy of the Federal Government, together with the increase of human resources, required the construction of an adequate facility in the municipality of São Gonçalo do Amarante-RN, for training and qualification and as a means of better enabling its personnel. Along with this policy, the Federal Government is also deeply concerned that its buildings be environmentally friendly. This study deals with this subject matter, as it develops an architectural design of a public building with an emphasis upon the reduction of energy consumption, through the study of energy performance factors such as defined by Carneiro (1988) and adapted by the author of the present study. It is known that residential, commercial and public buildings represent about 45 % of energy consumption in Brazil. That is why it is necessary to consider the reduction of such consumption in buildings, as well as the role that professionals, especially architects, play in this issue. The most effective participation in this regard in the field of architecture occurs in the design phase. However, the architectural solution proposed here goes beyond the energy performance factors, since it also involves other aspects, such as the definition of the concept, the parti and the spatial solution itself. In this sense, the architectural project of the Centro de Treinamento dos Servidores do IFRN - CTSIFRN (Training Center for IFRN Personnel – CTSFIRN) is particularly fitting as a subject for research at the Professional Master Program at PPGAU/UFRN, which is devoted to research on architecture, design and the environment.

In recent years, the Universidade Federal do Rio Grande do Norte (UFRN) has come through an intense process of expansion, common for the Instituições Federais de Ensino Superior (IFES) - Higher Education Institutions – since the implantation of the Programa de Reestruturação e Expansão das Universidades Federais (REUNI), a program of restructuring and expansion of the federal universities. The incentives made at UFRN can be seen into the expansion of the fields of teaching, research and extension, besides hiring human resources and adaptation / expansion of physical spaces. The focus of the UFRN at the technological area through the project (REUNI) has reflected in a significant expansion of the physical structure of the Center of Technology, area where the section of classes IV remains being the main set of rooms that supports the demand of the courses in the technological area, in which highlights the lack of classrooms. In this sense, the work presented here, proposes an architectural blueprint for expanding the physical space of this sector, based in this main parameters: (i) the spatial flexibility that attends the varying numbers of students per class; (ii) the environmental comfort, using the parameters and guidelines constructive for the Bioclimatic Zone 8; (iii) the requirements contained in the rules of ABNT NBR 9050:2004, 9077:2001 and NBR NBR 15220-3:2003. The architectural proposal used the maximum template allowed by the UFRN Central Campus Master Plan, four floors, considering the existing building (area equal to 7413.95 m²) as the ground floor and the extension proposed distributed on three floors, with an area of around 2,535, 00 m² each, making up a total of 7602.65 m² of total area built
