Análise estratigráfica de subsuperfície do Devoniano Inferior da Bacia do Rio do Peixe, Nordeste do Brasil

Subsurface stratigraphic analysis of Devonian strata from the Rio do Peixe Basin, newly recognized by palynological studies, has resulted in the identification of two new lithostratigraphic units assembled in the Santa Helena Group. The Pilões Formation, the lower unit, is composed mainly of dark mudstones and medium-tovery fine-grained sandstones, with minor conglomerates and breccias. The Triunfo Formation, the upper unit, comprises whitish grey, kaolinitic, coarse-grained to conglomeratic, cross stratified sandstones and conglomerates, with interbedded mudstones and fine-grained sandstones. These units were characterized using cores, sidewall and cuttings samples, conventional logs and image log, from three wells drilled by PETROBRAS, and 3D seismic data. The Pilões Formation is interpreted as prodeltaic facies, with lesser associated subaqueous talus, debrite and sandy turbidite lobe facies, distal part of fandelta and braided fluviodeltaic facies of Triunfo Formation. The Santa Helena Group corresponds to the Lower Devonian tectono-sequence deposited in a NW-SE-trending graben during a transgressiveregressive cycle. With 343 meters of thickness (isochore) in well 1-PIL-1-PB (Pilões 1), this sequence has a non-conformity at the lower boundary and its upper boundary is an unconformity with the Lower Cretaceous tectono-sequence (Rio do Peixe Group), that represents a hiatus of about 265 million years. Ignimbrites and coignimbrite breccias (Poço da Jurema volcanic breccia), related to an unknown pyroclastic volcanic event, were recognized at the northern margin of the Sousa halfgraben. Evidence from well data suggests that this event is coeval with the Devonian graben filling. The present study indicates a polyhistorical tectono-volcanosedimentary evolution of the basin. This lithostratigraphic update brings new perspectives for geological research in the Rio do Peixe Basin, as well as in other inland basins of the Northeastern of Brazil. The results of the research also contribute to the kwnoledge of the Borborema Province and western Gondwana paleogeography during the Early Devonian.

Representações arquitetônicas na concepção projetual: um estudo com arquitetos e urbanistas do Rio Grande do Norte

The architect materializes his ideas using architectural representations that acts differently during the design process, as instrument that expresses his creatives ideas, as communication between the designer and the client, or as project documentation for its execution (DURAND, 2003). In this paper, it’s been discussed the connexion between the architectural representations and the design process, in a professional context, focusing on representation as an aid to conception. The general aim is to understand the role of architectural representations in the design process by identifying ways of appropriation of their types and resources. The investigation was developed through the theoretical and conceptual studies about the mentioned themes, and the empirical and qualitative research, with architects from the state of Rio Grande do Norte, Brazil, which was developed in two stages: the first one, by filling an electronic form, and the second one, by case studies through execution of design exercises. The results of indirect research showed that the majority of architects and urbanists believes that the way it use the types and representation resources may interfere in design concept. And, after the completion of the case studies, was showed that, motivated by different design conditions, most designers has used the representations differently, which is reflected in different design conceptions.

Avaliação de sistemas de lagoas de estabilização em série no Rio Grande do Norte

Stabilization ponds are biological treatment systems in that stabilization of organic matter is performed by the bacterial oxidation and / or reduction of photosynthetic algae. This study aimed to monitor and evaluate the efficiency of stabilization ponds in the Rio Grande do Norte State. Collections were made of the treated effluent, made directly in the output boxes of facultative lagoons and maturation (M1 and M2) and raw sewage (EB) that arrived at the stations. The variables analyzed were: pH, temperature, dissolved oxygen, total suspended solids, chlorophyll "a", apparent color, total phosphorus, organic nitrogen, ammonia nitrogen, Kjeldahl nitrogen, turbidity, cyanobacteria density and concentrations of microcystin. Variance analysis (ANOVA one way) observing the premises using the Tukey test, so as to check differences between treatments. The evaluate the stations found to COD removals in the bands of 48,8% (Pipa) to 75,8% (Caiçara Rio do Vento) and 57,5% (Pipa) to 83,0% (Santo Antônio), respectively. The mean concentrations of cyanobacteria varied from LFs density of 62,545 cels.mL-1 (Pedro Velho Roça) cels.mL-1 to 2,669,048 (Ponta Negra), while the final effluent showed range between 9,072 Cels.mL- 1 (Pedro Velho Roça) to 1,899,981 cels.mL-1 (Macau – Ilha de Santana) and the average concentrations of microcystin the final effluent ranged from 0.02 μg.L-1 (Ponta Negra) to 0.15 μg.L-1 (Macau – Ilha de Santana) at the studied the stations.

Capparaceae: flora do Rio Grande do Norte e biogeografia no semiárido brasileiro

Capparaceae comprises 25 genera and 480 species, of which 110 are included in 18 genera in Neotropics. Its distribution is pantropical with high frequency in seasonally dry environments. Its representatives are woody, shrubs and rarely wines, with simple leave or compound 3-foliolate, shorts and deciduous floral bracts, tetramerous and nocturnal flowers with exserts and numerous stamens, ovary supero on a gynophore and fleshy fruits, dehiscents or indehiscentes. For Brazil, 12 genera and 28 species are recorded and 12 of that are endemic to the country, occurring preferentially in vegetation of savanna estépica s.str., seasonal semideciduos forest and restinga. This work shows two chapters. In the first chapter, the distributions patterns of the species occurring in the brazilian semi-arid region and their distribution intra Caatinga are discussed. The distribution patterns were determined from a review of the distribution of species in herbaria collections and supplemented with data obtained from specific bibliography about the family. A map containing 1 × 1 grid cells was used to evaluate the richness, collection efforts and floristic similarity of the species intra Caatinga. Six genera and eight species were registered in Caatinga. Four species are endemic to Brazil, with only one endemic to Caatinga, and the other four are widespread in Neotropics. Four distribution patterns were observed: restricted to the NE, broad and continuous in Brazil, disjunct and neotropical. All the species were recorded in Bahia, state with the highest species richness per grid cell and also remarkable sampling efforts species of the family. The state of Piauí presents priority areas for further collection of Capparaceae, due to low family representation in the state. The floristic similarity analysis intra Caatinga was low, 22 %, probably due to a few species of the family in the region and the wide distribution of the same. The second chapter presents the Capparaceae of flora to Rio Grande do Norte (RN), since the state has a little-known flora, with specific studies. Through collections in the state and herbaria review, five genera and six species of Capparaceae were recorded in RN: Capparidastrum (1 spp.); Crateva (1 spp.); Cynophalla (2 spp.); Mesocapparis (1 spp.) and Neocalyptrocalyx (1 spp.). Capparidastrum frondosum and Mesocapparis lineata are new records for the state. An identification key, descriptions and images, comments on the biology of the species and protected areas where they occur are showed.

Capital social e desenvolvimento de territórios: estudo multicasos nos territórios da cidadania do Rio Grande do Norte

This study aims to systematize elements for territorial development analyzing attributes of social capital present in the territories of Rio Grande do Norte. Unlike other studies about the subject, it is not intended to measure the stock of social capital, but rather to reveal the phenomenon of social organization and its implications, considering territories examined are already made around social capital structures. Case study were used as strategy research because it is enables to understand holistic features and significant events within the context of real life. For this research were selected representatives of public and social institutions involved in territorial collegiate specifically those of the governing core, selected from the more effective involvement of discretion in structure, functioning and meetings. The three territories have similar realities, are products of a public policy that is based on common criteria and present interdependence between categories of analysis of social capital. The presence or absence of any relationship - link, bridge or connection - influences the performance of territorial policy, affecting the social organization and fostering processes of access to information. In the cases at hand, despite the similarity of the general conditions of structure and function, the Apodi has qualities superior to the other. The presence of Dom Helder Camara project that articulates, in parallel to the Territory of Citizenship, the same actors of public policy with social mobilization capacity and effectiveness of actions, is able to encourage different development processes at Apodi. This can be explanatory factor, the tangent construct social capital, so that the territory present living conditions and better levels of development than the other two addressed here.

Dinâmicas de reprodução do comércio e os novos papéis urbanos de pequenas cidades norte-rio-grandenses: um olhar a partir das redes associativistas de supermercados

The work presented here aims to make an analysis of the socio-spatial dynamics of associative supermarket chains and their importance in redefining the roles of small urban North Rio Grande cities. The theoretical approach gives priority to business as a city constituent whose understanding allows us to seize the new socio-spatial dynamics of small towns in the face of globalization and which caused changes in the scope of its commercial forms. In this sense, we understand that trade, as an essentially urban activity has a very specific characteristic, with respect to its ability to transform the content and meaning of places. Another important factor in the construction work was the context of changes in the capitalist production system with the advent of flexible production and the determinations of the economic globalization process that brought new ways of organizing trade. The empirical analysis of the research includes two associative supermarket chains, the “Rede 10” and the “Rede Seridó”, bringing together basic elements for understanding the genesis and evolution of this new organizational model of trade in small towns of the state, as well as allowed -In understand the main changes in this segment of commercial activity. The methodology we used literature in books and periodicals, collected mainly secondary data collection with the SEBRAE and the ABRAS and was still a field research where interviews were conducted forwarded along to the associative network managers to supermarkets, owners of associated facilities and with consumers of the surveyed networks .Finally, we conclude that the formation and expansion of associative supermarket chains in the context of small cities potiguares is essentially in a survival alternative traditional small traders, that sharing the associative principles albeit somewhat rigidly guided by the training cooperation networks can not only stay in the market , but to impose as a new agent in the capital of the reproduction process. Thus, the associative supermarket chains in the search for new spaces, particularly within small towns end up promoting new momentum in these cities providing different flows and interconnections with different places, giving new content and urban roles. By taking not only the condition of the place of living, but also the place to reproduce the capital, small towns offer their population better able to make purchases, thus avoiding the mandatory population shifts to other urban centers in order to meet their consumption needs.

Esforços governamentais locais para o desenvolvimento: desenhos, tendências e limites dos Fundos de Desenvolvimento Industrial nos estados do Rio Grande do Norte, Maranhão e Ceará (1985-2010)

This research aimed to analyze the main government efforts to promote economic development in the Northeast, from 1985 to 2010, under the view that growth is crucial for increasing industrialization process and allows for more significant growth patterns. The analysis was the context in which state governments react to the abandonment of developmental line the federal level, in the 1980s, incorporating features of the actions called endogenous regional development and providing local players with greater responsibility in the development process. Justifies the need to analyze the following scenario: state governments in northeastern Brazil using relevant part of its resources to finance the installation and expansion of companies through tax incentives, with a view to generating income and employment, whilst waiting for an increase in output and a positive change in economic dynamism. In addition, it puts in question the fact that these policies receive such importance of state administrations for the purpose of achieving regional development. It was left to consider, therefore, the contents of the shares elected by state governments to examine the scope of these policies both in the pattern of growth, the transformation of the industrial sector and the development of the region attention to changes in state production structures. Due to limitations on the availability of data and time to carry out research, we were elected three states for the study: Rio Grande do Norte, Ceará and Maranhão. The study found that, despite the contribution of policies analyzed to economic growth, sub-national states are unable to compensate for the lack of development agencies structured at the federal level.

Políticas públicas, desenvolvimento local e participação social nas instâncias de governança associadas ao turismo no Rio Grande do Norte

In contemporary dynamics, a change is observed in the institutional structure of the state, culminating in several policies for the tourist sector which promote a new management format. The from this view, the Tourism Regionalization Macro Program (TRP), considered a significant program to Ministry of Tourism, arose as an answer to this new reality, having as strategy a joint working of structuring and promotion turned at decentralization of actions, valuing the residents participation in the search of the permanent dialogue between peers and revaluation of places and territories, based in the regionalization process. Based on this bias, this study aims to examine the role of the Tourism State Council of Rio Grande do Norte, with regard to the tourism planning, trying to understand it and solve it as governance Instance, through the Tourism Regionalization Program interventions, given the participation context of its actors and agents. For purposes of this study is delimited as time frame the year 2007 at 2014, understanding that it was this time, there was greater council members accession, as well as different types of sectors representation of civil society, as a result of a tourism public policy based on principles of innovation and participation. In relation to the research problem, this study is conceptualized as a qualitative and the chosen method is the materialist dialectic. Still on the methodological options, utilize the Content Analysis. The results show that the institutionalization of governance instance as the Conetur does not contributes, ideally, in the planning and management process of participatory and integrated tourist activity, facing a fair direction of your space production. The research indicates that there are debates, discussions and guidelines (still in a timely and targeted form), but not reverberates practical effects, by act in a conjuncture that Is strategically designed for political and economic power game, setting the hegemonic actors performance, which uses this arena to instill personal desires and wishes, that are decided in absentia to the council.

Semeando a cultura audiovisual no Rio Grande do Norte: a experiência das oficinas de vídeos do Coletivo Caminhos, Comunicação & Cultura

The audiovisual media is an instrument of communication that plays an important role in the cultural, social and political understanding of society. This survey was done intenting to identify the contribution of the audiovisual media to the culture in the Rio Grande do Norte and trying to understand the process of producing audiovisual in this state. To reach the aim, a case report was done regard the activities of Caminhos, Comunicação & Cultura – CC&C – a group that conducts cultural activities in the state since 2006 and has 76% of its activities related to audiovisual production, in which 47% of them, are video workshops. The video workshop project "Sowing Culture", held by the group in the city of Venha Ver/RN in January 2013, was observed and analised from its conception to its realization. The research pursued to reveal how the initiatives of independent producers, such as the CC&C group, can promote the access to audiovisual culture in regions where such knowledge is limited or nonexistent, due to the poor state policies related to the culture. Methodologically, the research was structured by performing a historical and descriptive analysis of hypothetical-deductive method through participant observation. For the conceptual and theoretical development, it was addressed the Sociability, Ethnography and media activism. The research proved that the independent audiovisual producers are promoting changes in the RN audiovisual practices. Before the background featured in the research, it is proposed a prognostic from researching to opening the RN Audiovisual Observatory, a communicational tool projected as space of sharing information, thinking, speaking, contacting and promoting the audiovisual productions of the state.

Visita interprofissional da cardiologia: uma estratégia de educação interprofissional na área da saúde na Universidade Federal do Rio Grande do Norte

The interprofessional education still represents a great challenge for the health education. This paper aims at implementing the Interprofessional Cardiology Visit (VIC, acronym in Portuguese) as a teaching strategy for the interprofessional education in the undergraduate and graduate courses of UFRN (Federal University of Rio Grande do Norte, acronym in Portuguese). It is a prospective and exploratory study held from March 2013 to November 2014, in the cardiology department of HUOL (Portuguese acronym for Onofre Lopes University Hospital), including health professionals from the mentioned hospital (doctor, psycologist, physiotherapist, dentist, social assistant, nutritionist, pharmacist and nurse), undergraduate and graduate students from the health courses of UFRN. The study happened in three parts: interprofessional activity planning; Implementation of the activity “Interprofessional Cardiology Visit (VIC)”; and Activity evaluation, this last one was made through focus groups. The process of planning and implementation of the VIC was described during the implementation phase: 60 meetings in which 1324 participants discussed one specific patient per meeting. After each case presentation, an interprofessional discussion was held, pointing out each professional’s specific point of view towards improving the overall care of that discussed patient. From the focus group analysis, five categories emerged: Recognition of previous participations in interprofessional activities; Conceptual vision of interprofessional activities; Impacts of the VIC to the patient’s care; Contributions of VIC to the professional training; and Challenges of VIC continuation. The making and planning of VIC process has reached its goals, despite of some health professional’s participation not being systematic due to work overload, such as the nurses’ case, as well as schedule difficulties. The VIC was praised as a successful experience and considered an initiative with positive impact for improving the care of patients with heart diseases. It is clear, from analyzing the discourses, that the VIC is a strategy which positively impacts both the care and the teaching. However, some difficulties remain, such as the lack of human resources and the challenge of making it systematic.

Competição espacial no mercado de revenda da gasolina: uma análise nas principais cidades do Rio Grande do Norte

This study aims to analyze the relationship between average price with the concentration in the markets (municipalities) in the state of Rio Grande do Norte, is using a little tool applied to the Brazilian market is the spatial econometric model. A data base contains all the stations of the major cities in the state of Rio Grande do Norte and includes 142 observations on stations was used. Theoretical models predict the relationship between the number of competitors in a market and the average price; these theoretical models include: the monopolistic competition of Perloff and Salop (1985), and the search-theoretic, of Carlson and McAfee (1983) and Varian (1980). The empirical results showed that a higher density within a geographic area is associated with a lower average price, thus converging with the monopolistic competition model and with the search-theoretic of Carlson and McAfee (1983). The parameters varied little with the inclusion / exclusion of control variables, showing the robustness of them.

Turismo rural no Rio Grande do Norte: desafios e perspectivas

The Rural Tourism appears as an economic alternative to the agricultural way, having to base itself on the revaluation of the local resources, as well as must be implemented through the local agents, a tourism of communitarian base. In this perspective the present objective work to analyze of that it forms if configures the tourist activity in the agricultural space of the Rio Grande do Norte, which the challenges and perspectives faced for the development of this activity. On the basis of this approach searched to argue on the deep transformations that the rural space comes suffering, with insertions of activities not-agriculturists, alternative for the effect of the economic reorganization, as well as on the public politics come back toward the Rural Tourism and an analysis concerning the activities of Rural Tourism that the Rio Grande do Norte comes developing and as this if it presents. As it arrives in port theoretical, we use the Concept of Territory, according to Saints, this if it makes pertinent in the conflicting analyses of the agricultural space for inside to embody of its conceptual picture the territorial dynamics substantiated by the relations politics, economic, social and cultural, where in them it made possible one better analysis in this process. As methodology bibliographical survey was used, in periodic, digital books, documents and interviews in some governmental spheres. The Great River of the North was evidenced that, signals for the development of the agricultural Tourism, therefore the state if presents with a gamma of potentialities, identified and developed some already being through some projects, however if it makes necessary a bigger involvement of all the spheres, considered basic so that this activity can be consolidated as plus a tourist segment in the RN.

O agrominerador familiar “Por detrás da Serra” de Parelhas, Seridó do Rio Grande do Norte

Unfavorable climatic conditions to family farming associated to the legal difficulty of retirement for workers who work exclusively in mining are indications provided by previous papers on this topic and guiding of such joint activities in a group that we have decided to call “agromineradores”, who are located “Behind de mountain” of Princess at Parelhas, Seridó do RN. However, in addition to these aspects, the research provides comprehensive analysis and thorough examination of other factors that link these families to such labor association. The theories of Habitus, field and trajectory from Pierre Bourdieu as well as the concept of institutions from Geoffrey Hodgson are central in this paper to explain the inclusion of these part-time farmers in an institutional environment shaped by social structures that influence in the choices of individual and collective behavior and leading to the relevance of the power structures within and outside the family, along with the role of public policies directed to family farmers and miners. The data analyzed showed that there is a crystallized structure that manifests themselves for years in this field, proving the link that exists between these agents and institutions that surround them in the composition of behaviors and routinizing of practices.
