Pirometamorfismo provocado por intrusões básicas cenozoicas em rochas da Bacia Potiguar, RN: integração de dados geológicos e petrofísicos

The Potiguar Basin is located in the Brazilian Equatorial Margin and presents sedimentary rocks affected by Cenozoic basic igneous intrusions, known as Macau Magmatism. The most prominent effect related to these intrusions is the formation of buchites, pyrometamorphic rocks that occur at very high temperatures and very low pressures in the sanidinite metamorphic facies. Through literature review, field observations, petrographic and petrophysical data, accessing the database of previous studies and results from this research, it was possible to characterize and estimate the effects produced in the thermal aureole of some hypabyssal bodies in the basin. The most relevant features associated with the intrusions are: compactation, hydraulic fracturing, partial melting and recrystallization of country rocks. According to the observed mineral occurrences, temperature of 800 to 1200 °C and pressure below 0,5 kbar were estimated at the contacts of the igneous bodies. The thermal modeling of the São João plug indicates thermal effects extending up to 150 m away from the contact and cooling time of approximately 265,000 years. After the peak of temperature, followed a cooling phase registered by remobilization and precipitation of minerals at low-temperature in faults, fractures and geodes, interpreted as derived from reactions with sedimentary rocks and metasomatic / hydrothermal fluids with abundant carbonatization and silicification.

A pedagogia de projetos e o ensino de música na educação básica da cidade de Natal/RN

This research aims to investigate the use of Project based learning as a method for teaching music in Elementary Schools located in Natal, RN. Its main objective is to analyze how this method is used during the classes of music at school context and which are its implications to the process of music learning acquirement. The specific objectives comprise: gathering the music teachers in preschool that work with project based learning as a method for their classes; identifying how the theory meets their practice; and analyzing how project based learning contributes to the learning process of music within schools. The main scholars adopted as theoretical reference were Boutinet (2002), Hernández (1998; 200), Antunes (2001), Cavalcante (2009), from Education area; and Penna (2008), Fonterrada (2008), Queiroz (2012), regarding Musical Education. Such choice was made in views of identifying the relationship and how project based pedagogy associates to the current Brazil school curriculum. For data collection, mixed methodological strategies were used, of qualitative and quantitative approaches that are complementary for better meeting the research needs. By applying a questionnaire, it was sought to identify the music schools and teachers who reported working with project based learning. Based on these results were selected two schools, one private school and one public school to perform a participant observation in two groups following the development of music classes based on project based learning, and the information were recorded in a diary of audio and video recordings. The results of this work show that the Project Education is a methodology frequently used by music teachers from Natal/ RN contributing to the integration of content and subjects and engages students in activities awakening interest and contributing to the development of music education at school. However, it was identified that many of the conceptions of the teachers about projects are confused by ambiguities from the use of the term in different areas and in various theoretical perspectives as well as the lack of publications that address the music education through the project based learning. It is hoped that this study provides discussions and research about the project based learning applied to music education in elementary school.

Empreendedorismo e Cultura: um estudo sobre empreendedores estrangeiros no RN

This present study analyses the relationship between national culture and entrepreneurship, in order to contribute in understanding the impact and the influence of Brazilian culture under the business practices of foreign entrepreneur on the tourism area of Rio Grande do Norte state. Researchers in entrepreneurship field, such as Schumpeter (2005), Weber (2006), McClelland (1972), Murphy, Liao, Welsch (2006), Peyrefitte (1999), Blanchflower (1988), Filion (2000), among others, and in the national culture, high-lighting Caldas and Woods (1999), Hofstede (1997) and Barros and Prates (1996), are put together to create a starting point to this present research, that reaches out for a differential approach, in order to create a correlation between Brazilian culture and the foreign entrepreneur, who chose Rio Grande do Norte state to live and invest. It was observed that in the case of the Switzerland entrepreneur, where the cultural difference is more strong, either in Hofstede's perspective than in Brazilian s authors, the management practices are more negatively affected. The rationalization adopted by the entrepreneur and the employee s logic are in battle in a day-to-day operation of the company. In the case of the Argentinean entrepreneur, the cultural difference exists, but it does not impact as much, because of her personal characteristics and the similarities of Latin culture than surfaces the differences. Finally, this study showed the necessity of analyzing the enterprising regarding the cultural issue, in a way to highlight the different rationalities in different atmospheres where it is practiced the enterprise

As pessoas na organização e o (re)alinhamento estratégico: o modelo de gestão da Alesat combustíveis em Natal/RN

Este trabalho consiste num estudo de caso na empresa Alesat cujo objetivo geral foi compreender o modelo de gestão de pessoas adotad por uma empresa norteriograndense à luz do modelo estratégico de gestão de pessoas. O estudo baseouse na literatura de Albuquerque (2002); Ashton, Haffenden e Lambert (2004); Fischer (2002); Legge (1995); Mascarenhas (2008); Tanure, Evans e Pucik (2007), Ulrich (2000) e Vasconcelos (2006), dentre outros, paa apreender como os profissionais que atuam no delineamento de estratégias e operacionalização das ações de recursos humanos concebem o seu posicionamento e eventual alinhamento à estratégia organizacional. O método analisou e descreveu o modelo de gestão de pessoas da empresa campo do estudo. A coleta de dados contou com a realização de entrevistas semi-estruturadas com os 05 gestores de RH que atuam na matriz (Natal/RN). Também foram coletados dados secundários, além de documentos e comunicações internas da empresa que tocam ao RH. Os dados coletados foram analisados à luz da análise de conteúdo de Bardin (1977). Através da análise, foi possível identificar políticas e práticas de RH que perpassam um modelo de gestão de pessoas bem definido e consolidado, com impactos mensuráveis no desempenho organizacional. Percebeu-se, também, a forte disseminação de uma cultura organizacional com foco no posicionamento estratégico e na informalidade e proximidade das relações, que permeiam o modelo de gestão de pessoas. Concluiuse a coerência entre as políticas estratégicas da empresa e as de recursos humanos. A pesquisa apreendeu as interfaces do modelo de gestão estratégica de pessoas da empresa; estas implicam uma alternância entre pensamentos e atitudes vinculados à versão hard, onde o papel das prática de RH é garantir que as pessoas alcancem os objetivos empresariais; e à versão soft, onde o papel do RH é desenvolver o capital intelectual e humano para diversificar os negócios e alcançar resultados sustentáveis e diferenciados. O salto qualitativo atingido pela Ale pode ser atribuído ao fato de possuir um RH situado hierarquicamente na alta cúpula da empresa, em posição de consultoria interna o que oferece perspectivas de atuação que vão muito além das rotinas operacionais desenvolvidas por boa parte das empresas no Brasil

...Em busca da realidade... : a experiência da etnicidade dos Eleotérios (Catu/RN)

The south region of the Rio Grande do Norte has been historically recognized as a place of old indian villages. Inhabitants of the edges of the Catu River, border between the cities of Canguaretama and Goianinha, the Eleotérios in the threshold of 21st century had passed to be seen and self recognized as "remaining indians" of the RN. Their ethnic mobilizations, when becoming public had placed to the intellectual and political fields an old question to be reflected on: the asseverations concerning the "indian disappearing" in the State. This item brings with it other implications. Accessed by a para-oficial indigenism, the Eleotérios had started to establish political relations with the Potiguara indians of the Baía da Traição/PB and the Indian Movement, feeling stimulated to produce and to reproduce forms of social differentiation. In this context, this research is worried about elucidating the process of construction of the ethnicity among the Eleotérios, percepted from the social relations and politics kept with the amplest society, into a particular historical situation involving sugar cane fields owners, proprietaries, militants, researchers, ambiental agencies. The effects of these political and social relations had been extended, making Eleotérios appear to the society as susceptible social actors to the specific policies for the aboriginal populations

Aqui o nativo é o caboclo... : O processo de construção da identidade cabocla em Mirandas/RN

Ce travaille de dissertation (Master) est le résultat de trois ans de travaille auprès de Mirandas, endroit situé à 22 kilomètres de la ville de Caraúbas, région ouest de l Etat du Rio Grande do Norte. Pendant cette période, on a compris que les habitants de Mirandas se identifient et sont identifiés pour les autres comme des caboclos , catégorie de classification que dans le discours courant, soit à Mirandas ou dans la siège de la municipalité, a des rapports avec la vision que les tous premiers habitants de Mirandas sont venus de la ville du Cabo , dans l Etat de Pernambuco. Et pourtant ; l usage qu a été fait de cette version a fini pour cacher des éléments qui ont défini l identité de Mirandas, tel comme la probable descendance indigène que parfois est actionnée dans les narratives qui montrent des rapports entre les portugais et des femmes indiens qu ont été pris à casco de cavalo (cheval) . (MACÊDO, 2010; CAVIGNAC, 2003). Donc, cette ethnographie porte à la lumière des éléments que sont utilisés pour les mirandenses pour définir leur identité. Cette identité peut être bien visualisé a partir des éléments que les caboclos font des signes diacritiques (BARTH, 1998; OLIVEIRA, 1976), bien comme des rapports établis entre les habitants de Mirandas et ces de Caraúbas. Des rapports qui ont rendu possible les manifestations d affinité et de conflits et que, donc, nous aide à entendre comme cette identité se réactualise dans ces rapports d union et opposition que les mirandenses construisent avec les caraubenses. Cela arrive dans les rapports territoriaux, économiques et de façon plus marquante, dans les rapports religieux.

A cidade sem barreiras é para todos?: avaliação das condições de deslocamento no bairro da Cidade Alta, Natal/RN

In this present work, the conditions of displacements and the behaviors of the users are evaluated, face to the physical adequacies in accessibility in the inserted area in the central quadrilateral of the Quarter of Cidade Alta, in the City of Natal/RN, space clipping established by its great meaning historical and cultural. For this reason such area was a target of an integrated actions plan during the years of 1993 and 1998, with the implantation of part of the Project CIDADE SEM BARREIRAS (City without Barriers) and, later, the implementation of the Project CIDADE PARA TODOS's proposals (City for All), having as supports the constant Brazilian norms inserted into the NB9050/1994 and in the Municipal law number 4.090/92, effective ones in the period of the interventions. Considering that the carried through actions at the time were directed to the elimination of the architectural barriers to guarantee the right to go and to come, the research received a human universe formed by all the people in situation of displacement in the central area of the interventions in the quarter of the Cidade Alta, independently of their locomotive or sensorial conditions, emphasizing the aspects most excellent how much to the accessibility of the sidewalk, as promotional of mobility, integration and urban organization, as well as of the public squares of that one quadrilateral, conceived, originally, as spaces of aggregation and social inclusion. The work appealed to the direct comment and the gotten results had been collated with the ex port facto law and technique norms, of the year of 2004, and with the legal devices contained in the Federal Decree number 5.296/2004, as way to certify the levels of efficiency of these adaptations in that it says respect to the current conditions of demanded accessibility and urban mobility

Qualidade do ar interior e conforto térmico : um estudo em espaços de estacionamento em Natal/RN

The recent tendency to utilize parking lots for other purposes has demonstrated that more time has been spent by visitors, mainly in great cities. Therefore, this paper investigates the thermal comfort and the air quality indoors in areas specifically used as parking lots by analyzing the direct relation between such environments and vehicular pollution. The thermal comfort and the quality of air indoors in parking lots with different architectonic typology (ground-floor and underground) are also studied, aiming to contribute to the proposition of suitable new areas designated to human usage. Field research was done, in two distinct periods within different weather conditions (January and July) in, two naturally cooled, parking lots located in Natal - RN. The internal environment agents were measured by using tools for air temperature, humidity, speed and direction; interviews with employees and visitors and chemical analysis through appropriate tools to analyze specific material, carbon monoxide and ozone. The results showed that chemical agents densely concentrate mostly in the closed parking space, aggravated by weather conditions, which dissatisfied the visitors. Still, it was shown that architectonic typology, alongside topographical aspects compromise internal environmental conditions, which increases the retention of pollution, leading to dissatisfactory thermal comfort levels and becoming less suitable for usage by visitors considering air and thermal comfort aspects. Consequently, they are not suitable for human stay due to the poor quality of the indoor air

Entre o mar e estrela, um lugar para se bem viver : a problemática da expansão urbana da Cidade de Baía Formosa/RN

The urban expansion problem of Baía Formosa, a southern edge city of de Rio Grande do Norte eastern coast, which has been presented in other coast Brazilian towns, specially on those with tourist activities increase. Therefore, this situation brings huge concerns to their inhabitants, to their technical /scientific community and to the governments, because of the conflicts of interest and of the growth of urban problems that this has been created. At Baía Formosa, the situation is aggravated because the city is confined, once around it, there are large private proprieties, environmental preservation area and the sea, at the eastern edge. The objectives of this study are the analyses of this city expansion process in order to obtain adequate alternatives and defining methodology to apply in other urban nucleus that are subjected to similar situations. Of course, presents social relations, environmental conditions and promoting local population insertion should be considered in order that enjoin this process and contributing to a better social balance. This case study has used bibliography research, field data, maps and soil occupation recorders and photographs of the area, besides the primary data gathering by surveys carried out with many social actors. The present analysis shows that the urban expansion observed today is featured by a recent unsustainable model, which attacks the environment and brings either farm conflicts. On the other hand, the ecological tourism can represent an alternative in order to achieve an adequate expansion form, without forgetting the several structural parameters necessary to support the sustainable activities

Percepção ambiental do patrimônio cultural: estudo de caso na Cidade Alta e Ribeira em Natal-RN

Contemporary studies have shown that the evolution of the heritage concepts is accompanied by an affirmation of the importance of social participation in recognizing heritage values and in managing cultural assets. We used the Brazilian context to emphasize the challenges for democratizing this process. This problematic is discussed based on the cases of Cidade Altaand Ribeira, neighborhoods that date from the formation of Natal-RNand have cultural assets recognized by levels of government. The study builds elements to answer the research question: what meanings and representations does the culturalheritage in the case study have for its users? The research method analyzes the representations and the meanings of the neighborhoods, firstly is based on historiographical studies, memories records of the city and on the process of heritage management. Secondly, it isbased on the field research, it is structured in environmental perception studies (areas of Environmental Psychology, Architecture and Urbanism) and has been applied with users with different bonds with the studied environment (residents, workers and visitors). The data were obtained with the multi-method which included direct observation, questionnaire survey and mentalmaps (that replicate Kevin Lynch). The analysis of result verified the research hypothesis, emphasizing aspects of the relationship between users and cultural heritage relevant to strengthening collective memory, local identity, contributing to heritage management. Among the results, the socio-environmental image obtained which emphasized a "cultural axis" linkingboth studied neighborhoods and confirms the influences of elements rein the memories records of the city and in the area s management. Identified aspects to strengthen the relationship between the users and cultural assets, such as the presence of placeswith affective ties to certain groups, as well as the need to fight off negative images (of degradation and insecurity) associated to the site and also expand the participation of the population, including residents, in policies and cultural activities. After all, recognition of value and the involvement of societycultural assets have the potential of contribute to integrate city development with heritage conservation

Influência de variáveis arquitetônicas no desempenho energético de hotéis no clima quente e úmido da cidade de Natal/RN

This master thesis aims to assess the influence of the design decisions on the energy building performance of hotels. The research is based on the integration of field study and computer simulation. Firstly, a detailed field study is carried out to identify the characteristics of hotels in Natal, Rio Grande do Norte. The items assessed are occupancies, light and equipment densities, types of air conditioning, total and monthly energy consumption, among others. A second and more comprehensive field study is carried out to identify the range of occurrence of architectural variables, with a larger number of buildings. A base case is modelled in VisualDOE, based on the first field study. Then, a first set of simulations are run to explore the sensitivity of the variables on the energy consumption. The results analyses were the base of a second set of simulations, which combined the most influential variables. The results of 384 models were assessed, and the impacts of design decisions were quantified. The study discusses tendencies and recommendations, as well as the methods advantages and disadvantages

Estádios larvais e ocorrência sazonal de imaturos de Psaroniocompsa incrustata (Lutz,1910)(Diptera:Smimuliidae) no Rio Pium, município de Nísia Floesta, RN

The larval instars, seasonal occurrence and environmental factors influence on Psaroniocompsa incrustata (Lutz, 1910) (Diptera: Simuliidae) immature were studied according to its physical and chemical aspects of breeding water. Four collects were made at vegetal substrate from margin, middle and floating on the Pium river, city of Nísia Floresta, state of Rio Grande do Norte, Brazil at dry and wet season. Some of larval characters were used to determinate the larval instars number like lateral length of cephalic capsulae, antennae and the distance among cephalic apodema, as well as pH, water temperature, width, depth, stream velocity, discharge and pluviometric precipitation were used for physical factors. Seven larval instars were determined for this P. incrustata community being the lateral length of cephalic capsulae as the best structure with this meaning propose. The seasonality immature abundance of this species were found in dry season and a positive correlation with pH, stream velocity and precipitation

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
