Em 1966 o Brasil chegava ao término do primeiro governo do regime militar. Disputavam o poder dois grupos das Forças Armadas, a Sorbonne e a Linha Dura. Esta indicou o nome do Ministro da Guerra Arthur da Costa e Silva como candidato à sucessão do Presidente Castello Branco. Costa e Silva fez campanha, percorrendo o Brasil para conhecer os problemas nacionais e apresentar suas propostas. O inusitado está no fato de a eleição ser indireta e apenas os membros do Congresso Nacional ter direito a voto, estando a população à margem da escolha do novo mandatário do país. O objetivo do trabalho é traçar o perfil do Marechal Arthur da Costa e Silva levantando fatos históricos que o tornaram, em 1966, um candidato viável à Presidência da República do Brasil e compreender a estratégia de marketing eleitoral utilizada. O trabalho utilizou como metodologia a pesquisa bibliográfica, entrevistas semiestruturadas com personagens que viveram a época e análise de conteúdo dos jornais O Estado de São Paulo e Jornal do Brasil, para indicar suas posições na cobertura das eleições presidenciais de 1966.

O objetivo do estudo consistiu em verificar uma possível alteração no tamanho da coroa clínica dos dentes ântero-inferiores em 50 indivíduos portadores de má Oclusão de Angle Classe II. A amostra foi dividida em 2 grupos: um grupo tratado com 25 indivíduos (14 do sexo masculino e 11 do feminino) com idade média em T1 (tempo inicial do tratamento) de 11 anos (dp = 9 meses), e em T2 (tempo pós-tratamento) de 12 anos e 7 meses (dp = 7 meses), tratados com o aparelho regulador de função Fränkel-2, durante 18 meses; e, um grupo controle com 25 indivíduos (12 do sexo masculino e 13 do feminino) com idade média em T1 de 10 anos e 3 meses (dp = 11 meses) e em T2 de 12 anos e 1 mês (dp = 11 meses). Os 100 modelos em gesso dos indivíduos foram analisados e comparados em relação ao início e ao término do tratamento por meio de um paquímetro digital, utilizando-se como medida a distância da borda incisal até a porção mais côncava da margem gengival dos incisivos e caninos inferiores. Os dados foram analisados por meio do teste t de Student e teste t pareado. Dentre os seis dentes ântero-inferiores, todos apresentaram aumento significante no grupo tratado, e apenas três dentes (33,42 e 43) apresentaram aumento significante no grupo controle. Já em relação ao grupo tratado e o grupo controle em T2, houve um aumento significante da coroa nos dentes 32, 33 e 43. Houve um aumento estatisticamente significante em apenas dois dentes (31 e 41) em ambos os sexos. Os resultados não demonstraram relevância estatística quando comparados com a alteração do tamanho da coroa no decorrer da idade. Conclui-se que as medidas das coroas clínicas dos dentes diferiram entre os grupos, sendo maior no grupo tratado. O aumento da coroa clinica dos dentes, não esta relacionado somente pela presença de inclinação para vestibular dos mesmo, mas pode ser considerado como multifatorial.

In the Brazilian network of psychosocial care, health professionals are important actors in the process of transformation of mental health public policies among various services. In the reality of psychiatric hospitals, one should understand the need to expand the debate about the current context of practices developed. This study aimed at analyzing the process of psychiatric reform and the mental health policy in the State of Rio Grande do Norte (RN) from the profiles and practices of higher-level professionals in two psychiatric hospitals. This is a cross-sectional and descriptive research, with quantitative and qualitative data, conducted in two psychiatric hospitals of RN. The universe of the target population was 95 professionals, taking into account the margin of error of 8%, non-response rate and the inclusion criteria: holding effective link with the institution by means of approval in public examination for, at least, six months, being state or municipal servant; having a minimum weekly workload of 20 hours in service; participating in care and/or activities with patients and families in a direct way. The final sample consisted of 60 professionals. The tool for data collection was a questionnaire with closed and semi-open questions about socioeconomic profile, and mental health policies, practices and training. Quantitative data were tabulated in the statistical software SPSS, and simple and bivariate statistics, chi-square type, was used for analysis by adopting the significance level with the value p<0,05. In order to analyze data, the content analysis of Bardin was used. The qualitative findings obtained with the semi-open questions in Analyse Lexicale par Context d'un Ensemble de Segments de Texte (ALCESTE) were grouped into four thematic axes: Professional action in mental health; Mental health training; Scenarios of psychiatric reform and psychiatric hospitals; Mental health policies and practices: challenges for professionals in hospitals. The profile of professionals has revealed the majority of women (89,7%), nurses (36,7%), aged 50-59 years (42,9%), weekly workload of 40 hours (52,4% ), time of completion of graduation from six to 15 years (57%), and 21,4% reported to have specialization in mental health. Regarding the practices developed in individual care, it was found an association between those who do not build or partially conducts the therapeutic project and those who conduct care related to observation and annotation. In family care, it was obtained care consultation during crisis; and, in group care, recreational activities. In the analysis of thematic axes, it was noted that, despite changes identified in the profiles and practices of higher-level professionals in care services for mental health, with the implementation of new public policies for this field, the findings indicate the confluence of asymmetries and divergences in the actions of the teams in psychiatric hospitals, difficulties in managing services, frequent readmissions, reduced quantitative of available services and equipment, high demand of users, disarticulation of the network of psychosocial care, and the very shortage of skilled human resources to compose these services. Accordingly, the evidenced scenarios partially outline the current political and ideological mismatch of the national process of psychiatric reform that denies the role of care actions conducted within hospitals, although it has not gone far enough with the creation of new services that justify the total extinction of this institution

In the coastal region of Ceará, between the municipalities of Acaraú and Itapipoca, thirteen sites were identified containing indicators of relative sea level, six of these being dated by optically stimulated luminescence (OSL) and radiocarbon. Ages obtained supports that were formed prograding beaches in the study area. In the eastern portion, beaches in coastal plain deposits occur while a system lagoon/barrier paleomangrove occurs in the western portion of the study area. In both cases the coastal deposits prograde from east to west. Higher sea levels were identified between the current: (a) 3.110-2.830 cal. yr. BP; (b) 1.830 yr. BP (OSL) - 1.490 cal. yr. BP; (c) between 1.240-1.060 cal. yr. BP; (d) 845-715 yr. BP (OSL). Since then the sea level suffered by lowering the current level. Variations in sea level are interpreted as responses to changes in the pattern of marine circulation and do not exclude possible tectonic disturbances in the basin of the continental margin. The indicators of relative sea level west coast of Ceará present differently from other curves constructed in the coastal northeast, suggesting that local factors mentioned above contributed to sea level fluctuations.

Systems of incised valleys have been studied in different continental shelves, including the Brazilian continental margin. The interest to characterize this feature is given by the information that it can provide variations on sea level, as well as the ability to host economically significant quantities of hydrocarbons in reservoirs located in deposits filling of the incised valleys. This thesis has the overall objective to characterize the morphology and sedimentary cover of the incised valley Apodi-Mossoró, located in the Northern Continental shelf of Rio Grande do Norte state, adjacent to Areia Branca city. The methodology included the integration of satellite imagery, bathymetric data, sedimentological data, shallow seismic, and the identification of foraminifera. The results indicate that the ApodiMossró incised valley is currently formed by two channels, shallow channel and deep channel, which have distinct morphological and sedimentological characteristics. The deep channel has connection with one of the heads of the Apodi Canyon, located in the slope area. The acquisition, processing and interpretation of shallow seismic data allowed the recognition of the depositional surface, erosional surface, discordance, and sismofaceis. The erosional surface mapped from shallow seismic sections is possibly a indicative of an ancient surface of valley incision, where it would probably be associated with the limit Pleistocene/Holocene. Different sismofaceis were identified and reflect the rise in sea level with standards sometimes agradacional, sometimes progradational. The thickness of sediments on this surface was estimated at a maximum of 22m thick in the central portion of the incised valley. Statistically, there are differences between the adjacent continental shelf and channels, and between these channels, for the content of calcium carbonate, organic matter, sand and mud perceptual, except for the gravel grain size. The analysis of living and dead foraminifera showed the presence of fifty species distributed in regards to morphology, depth and type of sediment. Four type of seismic echocharacteres were identified and mapped, as well as their bedforms, indicating different sedimentary processes along the incised valley. The integration of results suggests an activation of the Apodi-Mossoró incised valley in the Late Pleistocene.

This research starts from the presupposition that Cartilha do Silêncio(1997), a novel by the Brazilian writer Francisco Dantas, has a double articulated shift. One of the moves is towards the modern experience, with the idea that modernity is filled with contraries, as remarked by Nietzsche; the other is linked to the livelihoods ashore on traditional experiences, which encompasses the notion of memory as individual and collective ownership. The aim here is to analyze such perspective, social and critical issues within the characters' life stories that regards the calling of past as clear example that tradition is not gone, though modern life presents its own signs. Such dynamics gives to the plot a paradoxal feature. This work is mainly grounded on Marshall Berman' s thoughts in All That Is Solid Melts Into Air: The Experience of Modernity (1982) as well as on Antoine Compagnon'sFive Paradoxes of Modernity (1994). Assuming that Francisco Dantas' Novel is set as a split narrative, outcome of social memory originated on individual experiences aside social process and patriarchal family, this research brings into play the concept of memory by Jacques Le Goff in History and Memory (1992) along EcléaBosi's study in Memória e Sociedade: lembranças de velhos (1979). Keen to check how Cartilha do silêncio adjoins modern livelihoods with aesthetics order, the method articulates text and context, literary and social life, according to Antonio Candido'sLiteratura e Sociedade (1965). Thus, after reading the novel, it is possible to notice how the identity of the characters are built throughout the plot and it is also kept against settling on its social context during the transition from patriarchal tradition to modernity, creating a taut mood between both registries.

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.

Tourism is configured as an activity that presents constant movement could boost local development in the economic, sociocultural and human in locations with potential for structuring and such. Because it is a dynamic activity, tourism allows changes in its flow, extending the periods of seasonality. To this end, in view of the aforementioned dynamics, it becomes relevant to the presence of tourism planning, initially starting from the government so that it create laws and standards and develop projects for the management of activities in an orderly way, seeking citizen participation, making essential the presence of actors and agents in local tourism, expanding democracy and knowledge of their place of origin. In this scenario, the Ministry of Tourism is emerging with the National Tourism Plan which incorporates among its actions, the Regionalization Program Guide, adopting a model of regional local management, a participatory manner, through the bodies of governance imposed at the poles, and the shares of public policy in their various departments most responsible for promoting tourism in pole Seridó. This scientific work aims to analyze the pole Seridó, under the theory of tourism area life cycle (TALC) proposed by BUTLER (1980), locating actions for tourism and chronology of the locality applied the proposed process activity. For both the methodology is descriptive and exploratory, qualitative approach, historical, descriptive and narrative level, non-probability sampling, using secondary sources, through documents and other records occurred during the planning processes in the region, in order to have access to information related to the planning process of tourism in Seridó, using as a way to research the data collected the technique of content analysis. As a conclusion of this study it is observed that from the survey in relation to the history of tourism in the region, economic activities of livestock, cotton industry, mining and ceramics industry were responsible for the initiation of tourism in the locality through the flow directed to the same, the insertion of the first hotels and performing traditional events, giving rise to the demand for public policies that aided in directing the activity being, therefore, inserted into the engagement phase, the second phase proposed by BUTLER (1980) model, and the study was terminated with suggestions for the continuation of tourism in the region.

In order to evaluate the effect of levels of dehydrated cane juice sugar (DCJS) (0.0, 1.5, 3.0 and 4.5%) in the diet of European quail (Coturnix coturnix coturnix) on performance on performance, carcass characteristics and economical at 22 days of age indices, 192 quails cutting, were distributed in a completely randomized design with four treatments and six replicates of eight birds each There was no significant difference to the performance of quail in any of the periods. Quadratic effects of levels of DCJS on carcass weight (y = 173.71 + 4.2767x – 1.2644x², R² = 0.99), thigh-thigh more about (y = 36,055 + 1,1263x – 0,2256x², R² = 0.91) and abdominal fat (y = 3,3295 - + 0.8903x 0,19x2, R ² = 0,97) where the optimum levels were estimated 1,69; 2.50 and 2.34%, respectively. There was a linear effect descending of DCJS levels on weight breast with skin (y = 66.267 – 0.5653x, R² = 0.83) and without skin (y = 60.286 – 0.7193x, R² = 0.58). In economic analysis, one can observe higher profit to the producer with the use of conventional feed. However, between the levels of inclusion of sugar cane juice is observed that the level of 1.5% DCJS obtained the best results in economic analysis, obtaining only a difference of relative gross margin of 0.47% compared to conventional. It is recommended 1.69 and 2.50% DCJS for higher carcass, thigh + drumstick weight and lower percentage of abdominal fat quails, respectively.

The formulation of public policies, particularly those relating to social housing – SH -, follow a dialectical process of construction, which are involved in the figures of the State and tha Market.The combination of the State and Market remains in constant tension and struggle for power, which provides beyond products (policies, programs and projects), periods of crises and disruptions that can give rise to new institutional arrangements. It is possible to verify a change in the relationship between the State and the Market in the formulation of public policies of SH financing, justified by the context of the Brazilian economy growth, especially after 2003, year that began the first Lula Federal Government , and through the international financial crisis (in 2008). Thus, the State and the Real Estate Market has been undergoing a process of redefinition of their interrelations, articulating new arrangements, new scales of action and new logics of financial valorization of urban space. This peculiarity demanded the rapid thinning of speech and the proposals in the reformulation of housing policies, with the primary result within the pre-existing Growth Acceleration Program – PAC -, the release of My House , My Life – PMCMV -, established by Law 1.977 of the year 2009. Given the above, this research has as study object the relationship between financing public policies of SH, promoted by the State, and behavior of Formal Housing Market. It is believed that the established roles for each agent in the new housing finance model introduced with the PMCMV, have been adapted according to the needs of each location to make this a workable policy. It remains to identify the nature of these adaptations, in other words, what has changed in the performance of each agent involved in this process. Knowing that private capital remains where there is more chance of profit, we tend to believe that most of the adjustments were made on scale of State action. The recommendation of easing urban legislation taken by PMCMV points to how the State has been making these changes in activity to implement the production of social housing by this program. We conclude that in the change for PMCMV, the direct relationship for construction and housing projects financing began to be made between the Caixa Econômica Federal bank and the builders. The city was liberated from the direct interlocutor role between all actors involved in the production of SH and could concentrate on negotiating with the parties, focused on the effectiveness of SH public policies proposed by PMCMV. This ability and willingness for dialogue and negotiation of municipal government (represented by their managers), undoubtedly, represents a key factor for rapprochement between State and Real Estate Market in the City of Parnamirim.

The discussion about rift evolution in the Brazilian Equatorial margin during the South America-Africa breakup in the Jurassic/Cretaceous has been focused in many researches. But rift evolution based on development and growth of faults has not been well explored. In this sense, we investigated the Cretaceous Potiguar Basin in the Equatorial margin of Brazil to understand the geometry of major faults and the influence of crustal heterogeneity and preexisting structural fabric in the evolution of the basin internal architecture. Previous studies pointed out that the rift is an asymmetrical half-graben elongated along the NE-SW direction. We used 2D seismic, well logs and 3D gravity modeling to analyze four major border fault segments and determine their maximum displacement (Dmax) and length (L) ratio in the Potiguar Rift. We constrained the 3D gravity modeling with well data and the interpretation of seismic sections. The difference of the fault displacement measured in the gravity model is in the order of 10% compared to seismic and well data. The fault-growth curves allowed us to divide the faulted rift border into four main fault segments, which provide roughly similar Dmax/L ratios. Fault-growth curves suggest that a regional uniform tectonic mechanism influenced growth of the rift fault segments. The variation of the displacements along the fault segments indicates that the fault segments were formed independently during rift initiation and were linked by hard and soft linkages. The latter formed relay ramps. In the interconnection zones the Dmax/L ratios are highest due to interference of fault segment motions. We divided the evolution of the Potiguar Rift into five stages based on these ratios and correlated them with the major tectonic stages of the breakup between South America and Africa in Early Cretaceous.
