The present research aimed to analyze the presence of national scientific production in undergraduate studies in Psychology of Rio Grande do Norte. Therefore, the bibliographical references contained in education plan of subjects linked to the common center of the courses, which were taught in 2011 in three Psychology courses of the state, were focused. The analysis of the material was based on bibliographical and contextual aspects of the production, such as year, nationality, type of material, authorship (including the link of authors to PPGs), structuring axis of the subject in which it was mentioned, among others. The results showed that the national production is predominant in all courses, and they are, mostly, originated from PPGs of Psychology. Among these, the publications resulted from programs in Southwest, with emphasis to PUC-SP, are recent (mostly from 2000s) and they are predominantly composed by books (organizations and full texts). Regarding the distribution of Psychology PPGs production by the structuring axes, it is observed that it surpasses the foreign production only in axis C (procedures of scientific investigation and professional practice) and axis F (professional practices). Accordingly, it is concluded that Psychology production is found in graduation, sharing space with foreign publications and from other areas of knowledge. On the one hand, this is positive, by taking into account the importance of several foreign works and from other fields to build the knowledge in Psychology; on the other hand, it shows that the production from this area is inserted in graduation in a less significant way than its growth, which points out the existence of gaps in the development of some investigative domains from national Psychology

The clay swelling is today one of the major problems during the well drilling. Nearly 50% of clays that constitute shale expand easily in the presence of water molecules. During the drilling of a geological formation containing swelling clays, when is feasible the use of water base fluids, it is necessary to apply clay inhibitors. This avoids the incorporation of the cutting to the drilling fluid which is responsible for the wall swelling and crumbling. The aim of this work was to evaluate the synergistic behavior that occurs when swelling clay inhibitors are associated to NaCl and KCl salts. Three swelling clay inhibitors samples, INIB A, INIB B and INIB C, were analyzed. Each inhibitor was characterized by the amount of chlorides and active matter content. For the water-clay interaction evaluation in the presence of various fluids, it was used the Capillary Suction Timer (CST, Fann) and Linear Swell Meter (LSM 2000, Fann). For better interpretation of results, a Design of Experiments (DOE, Umetrics MODDE 7.0 TM) through Result Surface Methodology (RSM) was employed, taking into account the type, the swelling inhibitors concentration and the contact time with the clay. The results showed different efficiencies among the inhibitors employed, and the salt-inhibitors mixtures were more efficient than those products alone. However, for field operation, other parameters should be taking into account, as operational cost, environmental requests and time of application for each product

The catalytic cracking of triglycerides presents itself as a possible alternative to the production of biofuels with low emission of pollutants. In this work were synthesized the SAPO-5, the catalysts for the cracking reaction of soybean oil is presented. The solids were powder X-ray diffraction (XRD), thermogravimetric analysis (TG/DTG) and infrared spectroscopy (FTIR). The analyses indicated that the synthesis method has employed to obtain materials with high surface area and high acid. The soybean oil thermal and thermal catalytic cracking, realized from the room temperature to 450 ºC in a simple distillation system, has allowed obtaining two liquid fractions, each consisting of two phases, one aqueous and another organic, organic liquid (OL). The OL obtained from first fractions has shown high acid index, even in the thermal catalytic process. The products obtained in the cracking of soybean oil were analyzed by distillation, acid number, infra-red spectroscopy, density, viscosity, carbon residue, cetane number determination and characterization. The analysis of the products obtained in the presence and in the absence of the SAPO-5 permitted to conclude that all the solids tested presented catalytic activity in the deoxygenation of final products only at the second step of the cracking process

This master thesis aimed to investigate how the power relations operating in the tourism social processes, have shaped the urbanization of Ponta Negra district, Natal, Rio Grande do Norte - RN. The study assumes that the production of space is the result of global phenomena individualized by local forces a process of glocalization. The method used was the case study. It used primary and secondary data and information were treated using the technique of content analysis. The urbanization of Ponta Negra is inserted in the context of global process triggered in the 1970s. The Park of Dunas and Costeira Highway (PD/VC) urbanization project marks the beginning of the Tourisms since 1979. The period in focus was 1979 to 2009. The tourism was dived into four major sections time: tourism in Natal before the Coastal Highway (1939-1979); Project Parque das Dunas / Coastal Highway to the first boom in domestic tourism (1979 - 1990); the internationalization of tourism (1991-2000) and, of first "boom" to "decline" of international tourism (2001-2009). Based on the historical evolution of the tourism were elected three different social processes, able to demonstrate how relations of social forces brought in space act on them and help shape the process of urbanization of the neighborhood in question: The removal of beach hut , the soccer field Botafogo Football Club and the skyscrapers . Finally, it should summarize the research identified interests and conflicts among the actors that form the thrust of spatial transformations: cultural conflicts resulting from the imposition of social practices that differ from the taste of native; clashes between different groups that reflect the duality between use value and exchange value; and interests in land values. In addition, demonstrated that the social relations that involve the production of the area are stimulated by deep-seated societal processes historically and camouflaged by market relations and a modern facade that the city has acquired in recent times; revealed that the actors are linked in networks to increase their influence and that this influence varies mainly according to economic and political power that they or their associates hold

Na fase de tolerância à glicose diminuída (TGD) já estão presentes vários distúrbios metabólicos característicos do diabetes mellitus tipo 2 e fatores de risco que predispõem à vasculopatia. Nosso objetivo foi o de verificar se indivíduos de nossa população, com TGD e normotensos, apresentam elevação da excreção urinária de albumina (EUA) e da depuração de creatinina (D Cr). Teste oral de tolerância à glicose padrão com dosagem de insulina foi realizado, classificando os participantes em dois grupos: com TGD e com tolerância à glicose normal (TGN). Urina do período noturno foi utilizada para a determinação da EUA (imunoturbidimetria) e da D Cr. Os dois grupos não diferiram quanto à EUA e à D Cr. A freqüência de microalbuminúria foi de 21,1 e 3,3%, respectivamente, para os grupos com TGD e TGN (NS). Concluímos que, nesta amostra da população brasileira, indivíduos com TGD, normotensos e com resistência à insulina não apresentaram microalbuminúria e hiperfiltração glomerular.

In this work, we intend to discuss results from a research about retextualization in gender journalistic interview, considering speech dialogical approach. Retextualization activity, which implies the production of a new text through one or more basic texts, shows the presence of reported speech as an integral unit of discursive construction. Our corpus had been extracted from a section called Nossos Valores [Our Values], present at the syndical newspaper Adurn Notícias [Adurn News], from Federal University of Rio Grande do Norte (Brazil), which weekly publishes journalistic interviews with active professors from this institution. We describe retextualised text structure by correlating it to the one from the oral text, in order to identify and describe quoted speech, as well as features of the gender in which it is inserted. It was verified that, when it comes to reported speech present in the published interviews, which are representative of the research corpus, diverse incorporation procedures of alien property‟s speech take place, especially those regarding about reported speech use. The waterish presence of the other present in dialoged texts speech transformed in monologue texts demonstrates that there is not a clear demarcation among voices in certain parts of the written text. This is confirmed during analyses of the two interview versions, in which it is not always possible to distinguish the authorship of certain propositions, which in some way can point to Bakhtin‟s concept of intentional hybridity. Beyond Bakhtin‟s contributions (1990; 2000), the theoretical principles of this work are based upon Marcuschi (1986; 1999; 2001), Matencio (2003), Authier-Revuz (1982), and Favero et al. (1997; 1998; 1999; 2000)

O presente trabalho trata-se de pesquisa quase experimental para avaliar o impacto na redução do absenteísmo de usuários agendados para cirurgia eletiva, quando submetidos à confirmação de presença por telefone. O estudo foi conduzido no Centro Cirúrgico do Hospital das Clínicas da Faculdade de Medicina de Botucatu, durante trinta dias, perfazendo 89 usuários. Os resultados indicaram a efetividade da intervenção, que reduziu o absenteísmo em 30%. Recomenda-se sua implementação na antevéspera da cirurgia, possibilitando novas tentativas para encontrar o usuário no domicílio e convocação de outro. A criação de um núcleo de atendimento poderia constituir um canal de comunicação entre instituição e usuário, permitindo a confirmação da presença da pessoa e a oportunidade de sanar dúvidas sobre o tratamento e comunicar eventuais impedimentos à cirurgia. O núcleo demandaria um profissional com habilidade e conhecimento do serviço, uma vez que os usuários requerem orientações sobre o tratamento durante o contato telefônico.

Myofibroblasts are cells that exhibit a hybrid phenotype, sharing the morphological characteristics of fibroblasts and smooth muscle cells, which is acquired during a process called differentiation. These cells then start to express -SMA, a marker that can be used for their identification. Studies suggest that myofibroblasts are related to the aggressiveness of different tumors and that TGF-1 and IFN- play a role in myofibroblast differentiation, stimulating or inhibiting this differentiation, respectively. The objective of this study was to investigate the role of myofibroblasts in epithelial odontogenic tumors, correlating the presence of these cells with the aggressiveness of the tumor. Immunohistochemistry was used to evaluate the expression of TGF-1 and IFN- in myofibroblast differentiation, as well as the expression of MMP-13, which is activated by myofibroblasts, and of EMMPRIN (extracellular matrix metalloproteinase inducer) as a precursor of this MMP. The sample consisted of 20 solid ameloblastomas, 10 unicystic ameloblastomas, 20 odontogenic keratocysts, and 20 adenomatoid odontogenic tumors. For evaluation of myofibroblasts, anti- -SMA-immunoreactive cells were quantified in connective tissue close to the epithelium. Immunoexpression of TGF-1, IFN-, MMP-13 and EMMPRIN was evaluated in the epithelial and connective tissue components, attributing scores of 0 to 4. The results showed a higher concentration of myofibroblasts in solid ameloblastomas (mean of 30.55), followed by odontogenic keratocysts (22.50), unicystic ameloblastomas (20.80), and adenomatoid odontogenic tumors (19.15) (p=0.001). No significant correlation between TGF-1 and IFN- was observed during the process of myofibroblast differentiation. There was also no correlation between the quantity of myofibroblasts and MMP-13 expression. Significant correlations were found between MMP-13 and TGF-1 (r=0.087; p=0.011), between MMP- 13 and IFN- (r=0.348; p=0.003), as well as between EMMPRIN and MMP-13 (r=0.474; p<0.001) and between EMMPRIN and IFN- (r=0.393; p=0.001). The higher quantity of myofibroblasts observed in solid ameloblastomas, odontogenic keratocysts and unicystic ameloblastomas suggests that these cells are one of the factors responsible for the more aggressive biological behavior of these tumors, although the myofibroblast population was not correlated with TGF-1, IFN-, MMP-13 or EMMPRIN. The correlation between MMP- 13 and TGF-1 suggests that the latter induces the expression of this metalloproteinase. The present results also support the well-established role of EMMPRIN as an inducer of MMP-13. Furthermore, the relationship between EMMPRIN and IFN- and between MMP-13 and IFN- suggests synergism in the antifibrotic effect of these markers

Este estudo teve como objetivo descrever a população de profissionais do sexo, considerando características sociodemográficas, antecedentes gineco-obstétricos e comportamentais, e verificar a associação com a presença de doença sexualmente transmissível. Trata-se de estudo epidemiológico e transversal, realizado com 102 mulheres profissionais do sexo. Os dados foram obtidos por meio de entrevista e exames padrão-ouro para diagnóstico das doenças de interesse. A média de idade das mulheres foi de 26,1 anos, sendo que a maioria tinha nove ou mais anos de aprovação escolar, era solteira e teve coitarca antes dos 15 anos. A prática de sexo oral nos parceiros foi citada por 90,2% das mulheres, 99% delas relataram fazer uso de preservativo no trabalho, apenas 26,3% com parceiros fixos e 42,2% usavam drogas ilícitas. Não houve associação entre fatores sociodemográficos, antecedentes gineco-obstétricos e fatores comportamentais com presença de doença sexualmente transmissível e isso pode ser decorrente da escolaridade e do fato da população estudada possuir características muito semelhantes, dificultando o aparecimento de tais associações.

With process urbanization process the Brazilian cities have been goin through, Natal/RN does not differ from the other ones, it has had a fast, inordinate and planned urbanization, but not applied, it has caused a high increase of social environmental problems. One of the worrying problems observed is the change in the coastal landscape, which has caused serious damage to the city‟s population, more specifically, of Ponta Negra beach neighborhood. For the geographical studies, the issue, concerning the occupation of the beaches that has been getting higher and higher in the last decades is extremely important because these, in addition to being used as homes in the new urban configuration, have incorporated new ways of environmental interference, without a simultaneous advance of knowledge which would be necessary for a more suitable and rational use of litoral spaces. Thus, the current assignment aimed to focus the coastal landscape of Ponta Negra Beach, in the city of Natal/RN, checking and analyzing the effects caused by anthropic and natural action, and the way it reflects in the quality of life of the resident, working population and of the frequenters as well as the landscape transformations in the area which is object of study, from 1970 through 2010. The methodology used followed to stages, the first concerned the theoretical work bibliographic surveying and composition; and second one the empirical work marking of the environmental characterization and application of the questionnaires. So, we can measure that Ponta Negra, is very susceptible to environmental changes, the ones caused by the natural dynamics of the beach, as well as the human actions (society) in this really fragile and mutable space, so it needs, a more profound systematic study about the coastal landscape. In order to reach a minimization of the change of the landscapes in the coastal zones there must be an integrated management of the environments, based on the planning of actions and territorial reordination of the occupations of these so important spaces, environmentally, as well as socioeconomically. Whereas, only this way, we will have a sustentable development and a suitable use of that space

The broach presented in this dissertation, linked to post graduate Geography´s of the Universidade Federal do Rio Grande do Norte - UFRN, more exactly about the research group entitled interdisciplinary studies unit on space and housing built . The research developed through this study has this central theme on vertical grounding of the construction in the neighborhood of ponta negra in Natal, Rio Grande do Norte. Realizing this momentum as a way of accumulation of capital in city. Rio Grande do Norte´s city. During the 2000 s , the neighborhood of Ponta Negra went through an intense process of vertical integration of its ground, Provided by many factor of conditions created from new economic, political and social functions which start to be outlined mainly from the tourism development in this neighborhood since the 80´s decade. The Tourism development and the landing planning of the ponta negra´s neighborhood promoted for the government by using order to police the city´s urbanization, beyond the sense of the civilian building actors. They enabled this neighborhood to become propitious to the real estate investments. Many ventures were built before the year of 2010 while another are on building, which, over the years, changed the sociospatyal dinamics of the neighborhood. Considering the urban space is socially built, product and condition for the reproductive process of the capitalist society, the goal of this research is to investigate the verticalization of the ground, for capital reproduction purposes. This research aims to analyze the vertical this quarter through the theory of social production of space by Henri Lefebvre. The Methodology adopted pervades for secondary and primary research, compound for bibliographic research, documentary, journal, magazines, camp research and interview, to reach the best way to analyse the dynamics of the refered neighborhood

Cette étude a été fondée sur la reconaissance, la description et l'analyse du circuit spatial de la production de l activité des fabriques des casquettes dans la région du Seridó Potiguar. L activité des fabriques des casquettes est située dans les villes de Caicó, Serra Negra do Norte e São José do Seridó, qui forment le pôle de fabriques de casquettes, composé de soixante-quatre (64) unités de fabrication, le deuxième plus grand producteur de casquettes au Brésil. Dans la condition de base géographique, l'opérationnalisation du concept de circuits spatiales de la production a été essentielle à la compréhension de l'utilisation du territoire et de l'indivisibilité de l'espace, du fournisseur de matières premières au consommateur final, comprenant les étapes des matières premières, la main-d'oeuvre, le stockage, les transports, le commerce et la consommation dans la période actuelle, dans laquelle les instances de la production, la circulation, la distribution et de la consommation sont spatialement diffus. Sur la base de l'identification et de la localisation de ces étapes et des principaux acteurs impliqués dans la activité des fabriques de casquettes, une configuration de circuit spatial de la production a été élaborée, en s'interprétant l'utilisation des territoires par les instances productives. L'interprétation des étapes de production a identifié que les entreprises liées à l'Association Seridoense des Fabricants de Casquettes agissent plus efficacement sur le territoire que celles nonassociées, alors que toujours elles investissent dans des nouveaux équipements, en augmentant sa puissance technique pour se renforcer avant un marché si compétitif comme celui des casquettes. En examinant la contribution de la fabrication des casquettes à l'utilisation actuelle des territoires de la coupe, nous avons appris que les activités complémentaires et des matières premiéres nécessaires à sa réalisation se trouvent dans leur environnement géographique. Ainsi, la proximité spatiale entre les étapes de la fabrication des casquettes fait entrevoir la matérialité du territoire, conférée dans la coexistence des techniques passées et présentes, et l'ensemble des actions effectuées par un certain nombre de travailleurs sociaux qui collaborent à la création du circuit spatial de la production de l activité des fabriques des casquettes. Cette étude a confirmé que les fabriques des casquettes sont organisées sous la forme de cellules de production, continues ou discontinues, dont les équipements et les machines à coudre industrielles obéissent à la logique d'une production de plus en plus standardisée. Ce circuit spatial de la production contribue à l'utilisation actuelle des territoires de Caicó, Serra Negra do Norte et de São José do Seridó car il amplifie le mouvement du commerce et des relations entre les lieux, à travers la dynamique des flux des personnes, des biens et des produits, en constante circulation, guidées par la division du travail entre les étapes productives
