Faixas de proteção ambiental do Rio Pitimbu/RN: uma análise como subsídio ao planejamento e ordenamento do território

The Environmental Protection area sof Pitimbu river are important tools for planning and territorial land management. The Pitimbu river protection is aided in laws, so much of Federal stamp, as the Brazilian s Forest Code (Law No. 4771/1965), and in State s and City s Resolutions. So, this research begins in the State s Law No. 8426/2003interpretations, for being the most restrictive in the river's margin occupation and management. The objective is to analyze the applicability of the Environmental Protection areas of Pitimbu river, localized at the State of Rio Grande do Norte, considering environmental legislation and how to use this space by the man. Having specific goals for the discussion of the legislation s scope to this river; the identification of the types of soil s covering and evaluation the effectiveness of Law Nº.8426/2003, as protection instrument and land management. The river is characterized by its ecological importance and for feeding the Jiqui pond, an important reservoir that supplies 30% of drinking water to the east, west and south population sof the capital of the State. Pitimbu river is passing by a process of environmental degradation, originating from actions as deforestations of its ciliary forests by intensive agricultural practices; introduction of urban and industrial effluents leading to its contamination; increase of the pluvial drainage; erosion, sedimentation and discharge of urban waste , along with pressure for urban settlements along its banks. Under the methodological point of view is part of theoretical planning and land management research, and from a vision of social and environmental spaces. It was produced a survey map of the soil s covering, with 16 classes. Divided into coverage and disturbed natural covering. Using the 300 meters spatial limits of the Environmental Protection Strip, according to the State Law. The survey highlighted a higher percentage of classes disturbed, indicating man s interference in the balance of that system, as well as the lack of environmental actions. Leading to the degradation of riparian areas, and lack of conservation of water resources. Finally, it was considered that the strips of environmental protection are not effective as the preservation and territorial ordination

Reservatório Tabatinga (Macaíba-RN): qualidade ambiental, conflitos e uso

The reservoirs are water sources built along the fluvial basins, between rivers and dams made by concrete or earth. In Brazil they are built for different purposes, standing out the generation of energy (hydroelectric power station), flowing regulation, water reserves and flooding control, therefore they have played and still play an important role in the modern society.In the Northeastern semiarid region, they are typically used to supply cities and as a source of food.In the state of Rio Grande do Norte, the large reservoirs are intended for the same purpose.The cities settled in the riverbanks, or which have river channels crossing them, face flooding related problems. In the city of Macaíba-RN, flooding occurred systematically during the rainy season, causing great inconvenience to the local population.As product of the collective claim Tabatinga Reservoir in Jundiaí river was built, upstream of the city. Facing this background, this thesis aimed to assess the sócio-environmental quality of this reservoir.To achieve this goal, methodologies pointed to assess water quality along with the aplication of a questionnaire were used aimed to verify the quality of water and to know the perception of the residents from urban and rural área settled near to the reservoir was performed. The results showed the existence of conflicts of residents of rural communities and the presence of the reservoir, while for the city's population, the reservoir is considered not only the right solution to solve flooding in urban areas, but also as economic source for the rural population. Considering the water source assessment, this study concluded that the Tabatinga Reservoir is unfit for human use, due to the presence of metals of toxicological significance with the potential to elicit damage to the genetic material of individuals that use water from this reservoir, leading to cause serious risks to health population.

A neuromodulação do córtex pré-frontal dorsolateral na percepção de tempo em contexto neutro ou emocionalmente ativo

The time perception is critical for environmental adaptation in humans and other species. The temporal processing, has evolved through different neural systems, each responsible for processing different time scales. Among the most studied scales is that spans the arrangement of seconds to minutes. Evidence suggests that the dorsolateral prefrontal (DLPFC) cortex has relationship with the time perception scale of seconds. However, it is unclear whether the deficit of time perception in patients with brain injuries or even "reversible lesions" caused by transcranial magnetic stimulation (TMS) in this region, whether by disruption of other cognitive processes (such as attention and working memory) or the time perception itself. Studies also link the region of DLPFC in emotional regulation and specifically the judgment and emotional anticipation. Given this, our objective was to study the role of the dorsolateral prefrontal cortex in the time perception intervals of active and emotionally neutral stimuli, from the effects of cortical modulation by transcranial direct current stimulation (tDCS), through the cortical excitation (anodic current), inhibition (cathode current) and control (sham) using the ranges of 4 and 8 seconds. Our results showed that there is an underestimation when the picture was presented by 8 seconds, with the anodic current in the right DLPFC, there is an underestimation and with cathodic current in the left DLPFC, there is an overestimation of the time reproduction with neutral ones. The cathodic current over the left DLPFC leads to an inverse effect of neutral ones, an underestimation of time with negative pictures. Positive or negative pictures improved estimates for 8 second and positive pictures inhibited the effect of tDCS in DLPFC in estimating time to 4 seconds. With this work, we conclude that the DLPFC plays a key role in the o time perception and largely corresponds to the stages of memory and decision on the internal clock model. The left hemisphere participates in the perception of time in both active and emotionally neutral contexts, and we can conclude that the ETCC and an effective method to study the cortical functions in the time perception in terms of cause and effect.

Atmosferas arquitetônicas: projeto e percepção na obra de Peter Zumthor

This thesis will discuss the topic architectural atmospheres, based on Peter Zumthor's works and narrative. The subject "architectural atmospheres" is defined in the study as the "complex and general condition, realized by the user during the experience of a place". Atmospheres are composed of the overlap of all physical qualities that compound a space and its perception, conditioned by individual issues of the user. The atmosphere is realized through all human body receivers, in a multi-sensorial process, and affects qualitatively the spacial experience of the places created by architecture. The study has three chapters. The first chapter is a reflection on the issues that architectural atmospheres present. It passes through the concept and definition of the subject and includes a compilation of design principles that act on the architectural atmosphere composition in a variety of projects by a range of professionals. In the second chapter, the procedures adopted by Peter Zumthor in his design process that focus on atmosphere composition are studied. In the third and last chapter, Brother Claus Chapel (Wachendorf, German) and Kolumba Museum (Colon, German) projects, both by Peter Zumthor, are analyzed, in order to comprehend the complex role of elements that constitute the architectural atmosphere of each of these places. The methodology used throughout the thesis consists of bibliography and documental analysis, based on books, plans and material searched on Internet. Furthermore, the project analysis counted with the personal experience of the author of this thesis upon visiting the studied buildings. Finally, in conclusion, it is realized that when architecture is made in order to touch the user, expressed by its built objects, it can be provide a vast conceptual and theoretical basis that valorizes and enriches the experience of its use. It (the architectural atmosphere) is related to an approach that uses the same elements of any other construction, but distinguishes itself by the connections that it implies with humans and its environment. In the face of new patterns unveiled for contemporary architecture, this study contribution is based around the opportunity to understand this particular relationship between user and architectural object, identified as a phenomenological approach of architecture, as well as to update the subject bibliography, still scarce among Brazilian universities.

Praias urbanas e racionalidade ambiental: avaliação da gestão, das intervenções urbanísticas e dos usos na praia de ponta negra

This dissertation addresses issues considered essential for sustainable development of urban waterfronts and beaches. Many of these spaces, even though they are of public authorities, economic market and general population interests - due to its landscape, its importance for recreation purposes and as a basis of " Sun and beach Tourism " (Turismo de Sol e Praia), among other factors - have shown aesthetic, health and cultural degradation, entailing environmental, economic and social losses and conflicts. Based on this perception, the research aims to understand the main reasons for these negative results for beach spaces. To this end, it was chosen the case study of a typical urban beach, Ponta Negra Beach, located in Natal, RN. Ponta Negra is associated with the "postcard" of the city and it has been deserving of municipal urban planning legislation that legally recognizes the importance of its landscape. Also it has received constant investments by the Government through urban projects, arguing to leave the site attractive to its users. Nevertheless, in the last fifteen years, the beach has lived with the expansion of its problems, such as those related to bathing water, to coastal erosion, and to the mangling of its natural surroundings. Social conflicts have also been frequent in this time frame: conflicts between residents of the waterfront and traders who work on the beach, between the traders themselves, between the managers of space and fishermen, between managers and formal and informal traders. Many of these social and environmental conflicts have taken such grand proportions that became legal matters. Assuming that the problems identified are related to the issue of rationality - understood as a system of values, norms and actions that relate means and ends - and upholding the need for focused research on "environmental rationality" to understand and interpret the dynamics of social and environmental problems encountered on site, the research that guides the study relies on the Mexican economist Enrique Leff's theory on "environmental rationality" which, briefly, can be defined as a system of values, norms, actions and means and ends relations based on the principles of environmental management and sustainable development. Among other aspects, rationality encompasses cross-sectional planning of public administration, the participation of society in the management of environmental resources, interdisciplinary reorganization of knowledge, the clash of opposing interests and the conciliation of common goals of different social actors. The study evaluates the relationship between "environmental rationality", as proposed by Enrique Leff, with the management, urban interventions and uses observed in Ponta Negra Beach. For that, some benchmarks were established and considered in the research as related to sustainable development of the "beachy" atmosphere. Analytical instruments chosen were the urban transformations and the environmental and social problems that have been the target of lawsuits. Also part of the study, the problems that were the subject of civil investigations, which are investigation procedures carried out by the Prosecutor's Office.

Educação ambiental como estratégia para inserção da sustentabilidade na formação em odontologia

This thesis proposes environmental education as a strategy for the inclusion of sustainability in the academic education of higher level. The dentistry course has been the object of study, which is justified by the recognition of the need for reflection on environmental issues in the dental academia, initially based on professional experience of the author as a dental surgeon. The aim of this study is to investigate the scientific production of dentistry and its content related to environmental issues, in addition to expanding discussions and reflections on the need to insert environmental education as academic content. With the specific purpose of verifying the amount and analyze the content of scientific articles involving issues related to sustainability in dentistry, Chapter 01 presents research in leading journals portals available on the internet. Works were surveyed where sustainability and related issues were present and placed in a theoretical framework that analyzes the dental service inclusion in the dominant economic model. These procedures are intended to prove the hypothesis that the dental profession does not produce significant scientific content that relates the profession to the environment and sustainability. A literature review was conducted with the statement of dentistry changes from its origins to the front position to the dominant development model and exemplification of the deleterious effects of this model on the environment. In addition, there was a scientific research in journals portals available on the internet and investigated the amount and content of scientific articles involving issues related to sustainability in dentistry. Chapter 02 has the specific purpose of providing content to expand discussions and reflections on the need to insert environmental education in undergraduate courses in dentistry, such as insertion strategy into a new development model guided by sustainability. In this, students questionnaires were given the 8th dentistry course of the period the Federal University of Rio Grande do Norte (UFRN), to be understood environmental perception of learners and were obtained grants for proof of the thesis that environmental education applied dentistry has the potential to make people aware and willing to act practicing and propagating sustainability in their conduct. The overall results indicate little scientific production, as the research and work that relates to dentistry to sustainability and the issues related to the environment have not significantly been present in the syllabus of the undergraduate courses in dentistry, despite the interest shown by survey respondents When such issues are addressed. In this context, it is proposed fostering actions to environmental education, so that dental professionals are engaged in the construction of a new development model based on sustainability, as despite the environmental theme seems to be little explored in the academic and scientific world of dentistry, there interest from students and great potential multiplier for appropriate environmental behavior. After proving the hypothesis that the environment-related content are poorly explored in the academic and scientific world of dentistry, the main conclusions were recognizing the importance of environmental education as an interdisciplinary tool for environmental thematic approach in undergraduate courses dentistry, in addition to implementing this new pedagogical proposal in the professional practice of dentists, given their potential multiplier for environmental knowledge.

Práticas sócio-ambientais no espaço escolar: uma reflexão sobre a percepção dos usuários de duas escolas do ensino fundamental em João Pessoa, Paraíba

In the social-historical moment we live in, it is each time more evident the necessity of the people to learn to deal with the environment in conscientious way, taking care of themselves properly through it. In this direction, considering the school as a place where children, young and adolescents spend great part of their time, this work had as objective to examine the perception of school environment for students, professors and employees of two schools in João Pessoa city - Centro Estadual Experimental de Ensino-Aprendizagem Sesquicentenário and Escola Estadual de Ensino Fundamental e Médio Presidente Emílio Garrastazu Médici (Experimental State Center of Learning-teaching Sesquicentenário and Basic and High State School Education Emilio Garrastazu Médici President). From the presupposed that the environments in which and with which people live reflect their daily practices, the field work searched to identify the social-environmental practices that characterize the relation of these users with the school and, from this understanding, to infer some of their concerns regarding the environment as a whole. To analyze the use of the available physical space in the two institutions it was opted the use of the After-Occupation Evaluation, one of the approaches that feed the process of building production or built set, rescuing aspects related to its use, operation and maintenance. Besides analyzing diverse school environments (such as classroom circulations/accesses, library, pedagogical and sportive spaces) in relation to the environmental comfort and the perceptions of the main users of the schools (pupils, professors and employees), the dissertation tried to inquire the care (ambient education) of these users with the school space. In general, it was verified that the two schools have evaluations and perceptions really different for four reasons: (i) management of the schools; (ii) the users perception; (III) localization of schools and (IV) feeling of place, territoriality and appropriation

Mobilidade urbana sustentável em projetos estruturantes: analise urbanística e ambiental do corredor de transporte da Avenida Bernardo Vieira Natal/RN

The search for a sustainable urban mobility, has recast the public policy of transport and movement for all, in order to contribute to the welfare economic, social and environmental. Within this context, has as its main objective review here in the city of Natal in the state of Rio Grande Norte, the deployment of the new road infrastructure of the transport corridor of Bernardo Vieira Avenue and checking at least with regard to urban areas and environmental chosen here, as will indicators to assess sustainable urban mobility, that the theory has been well constructed, but in practice little way to apply the proposed guidelines for sustainability. To achieve this result, is initially a literature review with the principal investigators of the matter, since the concepts of indicators of sustainable urban mobility. And a second time, participating in to the case study, using the methodology of environmental awareness, through analysis photographs, notes and testimony in the study area ace to reach conclusions

Um olhar sobre o patrimônio histórico-arquitetônico de Assú/RN: análise com base na percepção dos usuários e no ponto de vista técnico

This research analyzes the actual Historic-Architectural Heritage of Assú City which is located in Rio Grande do Norte State, Brazil, the study is based on both Assú s residents perception and technician s viewpoint. It looks forward to expose this community s relationship with the existing number of historic buildings, the scale of people s identity to the place and the association of this perception toward the preservation and conservation s scale of the historic settlement. Since the contextualization of the degradation s process of central areas, the study draw nea initially the conceptual aspects, focusing on the debate about heritage and the preservationist practice. The work complements the discussion through an approach on people-environment relationship and environmental perception, considering relevant factors for planning process. The obtained and presented data had diagnosed the condition of the architectural pile and also allowed this work to formulate recommendations for the studied area and architectural set in order to contribute for future urban politics implementation that consider the building, which are not only important to the considered population, but to the Rio Grande do Norte s History, as well

Caracterização ambiental de bancos areno-lamosos nos campos petrolíferos de Macau e Serra (RN), como subsídio às medidas mitigadoras ao processo erosivo

On Rio Grande do Norte northern coast the process of sediment transport are intensely controlled by wind and sea (waves and currents) action, causing erosion and shoreline morphological instability. Due to the importance of such coastal zone it was realized the multi-spectral mapping and physical-chemical characterization of mudflats and mangroves aiming to support the mitigating actions related to the containment of the erosive process on the oil fields of Macau and Serra installed at the study area. The multi-spectral bands of 2000 and 2008 LANDSAT 5 TM images were submitted on the several digital processing steps and RGB color compositions integrating spectral bands and Principal Components. Such processing methodology was important to the mapping of different units on surface, together with field works. It was possible to make an analogy of the spectral characteristics of wetlands with vegetations areas (mangrove), showing the possibility to make a restoration of this area, contributing with the environmental monitoring of that ecosystem. The maps of several units were integrated in GIS environment at 1:60,000 scale, including the classification of features according to the presence or absence of vegetation cover. Thus, the strategy of methodology established that there are 10.13 km2 at least of sandy-muddy and of these approximately 0.89 km2 with the possibility to be used in a reforestation of typical flora of mangrove. The physical-chemical characterization showed areas with potential to introduce local species of mangrove and they had a pH above neutral with a mean of 8.4. The characteristic particle size is sand in the fine fractions, the high levels of carbonate, organic matter and major and trace element in general are concentrated where the sediment had the less particles size, showing the high correlation that those elements have with smaller particles of sediment. The application of that methodological strategy is relevant to the better understanding of features behavior and physical-chemical data of sediment samples collected on field allow the analysis of efficiency/capability of sandy-muddy to reforestation with local mangrove species for mitigation of the erosive action and coastal processes on the areas occupied by the oil industry

Avaliação ambiental de manguezais adjacentes aos campos petrolíferos de Macau e Serra (RN), como subsídio às medidas mitigadoras ao processo erosivo

Among the various effects caused by the climate change and human intervention, the mangrove ecosystem changes through of the years has been worth mentioning, which hasn t known which are the pros and cons for the adjacent coastal and estuarine environments yet. It happens due to the present dynamism in these areas, besides of the difficult understanding of the processes associated with evolution. This study aimed to environmentally evaluate adjacent mangroves from the Macau and Serra oil fields, located on Rio Grande do Norte northern coast, to support the mitigating actions related to the containment of the erosive process, as well as, according to the principles of the Clean Development Mechanism (CDM), to assess the amount of atmospheric carbon sequestered by the studied ecosystem. An inventory was conducted through mangrouve mapping which has supplied this research, especially regarding to the structural characterization of mangrove areas. To understand the local mangrove behavior in a greater level detail, techniques of remote sensing, GIS and GPS were used to make an analogy between the current and past states of the mangrove studied, allowing to make anticipated projections for the future impacts or changes in that region. This study combined data from multispectral LANDSAT 5 TM, Landsat 7 ETM+ with radar microwave data from SAR RADARSAT-1, which increased the interpretation capacity of the data from optical sensor systems. The interpretations have been supported by the data field, representing a better and innovative methodology for the environmental and taxonomic characterization of mangrove forests considered. The results reveal that mangroves of the Ponta do Tubarão Sustainable Development Reserve are biologically representative areas and providing a variety of benefits, especially for local communities, constituting the priority sites for actions development aimed at conservation. They also have been showing the necessity to make mitigating measures in order to recover degraded areas through reforestation or creating new areas of mangrove, as currently 7.1% of the mangrove forests studied are dead or in an advanced state of decomposition. The amount of atmospheric carbon sequestered proved very significant when analyzed for the whole area, which is able to sequester atmospheric 4,294,458 Ton CO2 per year

Design gráfico da pluma de contaminação por compostos orgânicos voláteiss utilizando software CAD na investigação de passivo ambiental em um posto revendedor de combustíveis em Natal/RN

Among the potentially polluting economic activities that compromise the quality of groundwater are the gas stations. The city of Natal has about 120 gas stations, of which only has an environmental license for operation. Discontinuities in the offices were notified by the Public Ministry of Rio Grande do Norte to carry out the environmental adaptations, among which is the investigation of environmental liabilities. The preliminary and confirmatory stages of this investigation consisted in the evaluation of soil gas surveys with two confirmatory chemical analysis of BTEX, PAH and TPH. To get a good evaluation and interpretation of results obtained in the field, it became necessary three-dimensional representation of them. We used a CAD software to graph the equipment installed in a retail service station fuel in Natal, as well as the plumes of contamination by volatile organic compounds. The tool was concluded that contamination is not located in the current system of underground storage of fuel development, but reflects the historical past in which tanks were removed not tight gasoline and diesel
