Mapeamento da isoterma de Curie na Bacia do Parnaíba estimada através da profundidade da base das fontes magnéticas

Located on the western edge of the Brazilian northeast, the Parnaíba Basin is an intra cratonic basin with oil production. This study aims at understanding its genesis and evolution, using aeromagnetic and gravity data. We used the spectral analysis of aeromagnetic data to map the depth to the bottom of the magnetic sources in order to assimilate this depth with the depth of the Curie isotherm, and infer the geothermal gradient. Using the spectral analysis technique, we succeeded in mapping the surface of the depth to the bottom of magnetic sources (SBFM), which marks the depth that occur magnetization. In the Parnaíba Basin the SBFM presented depths around -20,5 and -28,5 , which was consistent with an inversion of the same dataset using the technique of Magnetization Vector Inversion (MVI). Furthermore, SBFM topography correlates well with Moho depth, which was estimated from satellite gravimetric data from the GOCE mission (Gravity Field and Steady-State Ocean Circulation Explorer). Assuming that SBFM coincides with the Curie isotherm of magnetite (ICM), defined as the surface at which magnetite ( ) looses its ferromagnetic properties, it was possible to estimate the geothermal gradient. The geothermal gradient in the basin showed values between 19.2 and 26.5 , allowing to estimate the heat flow for the Parnaíba basin after assuming a conductivity of 2.69 . The resulting heat flow values ranged between 51.6 and 71.3 , which is consistent with values found in other works throughout the South American continent. Lithospheric thickness using an empirical relationship, finding values between -65.8 and -89.2 . We propose that thermal structure of Parnaíba basin is influenced by a deep thermal anomaly. This anomaly has heated the lithosphere beneath the basin and has resulted in relatively thin values for the lithospheric thickness and relatively high surface heat flow values. The origin of the anomaly is not clear, but the correlation between Curie depth and Moho topography, suggests that tectonic extension processes could have played a role.

Avaliação do efeito da inibição do reparo de sítios abásicos na resposta inflamatória celular

Base excision repair (BER) proteins has been associated with functions beyond DNA repair. Apurynic/apyrimidinic endonuclease 1 (APE1) is a multifunctional protein involved in a plethora of cellular activities, such as redox activation of transcription factors, RNA processing and DNA repair. Some studies have described the action of the protein 8-oxoguanine (OGG1) in correcting oxidized lesions in promoters as a step in the transcription of pro-inflammatory cytokines. Despite being especially important in redox activation of transcription factors such as nuclear factor κB (NF-κB) and AP- 1, the repair activity of APE1 has not yet been associated with the inflammatory response. In this study, experimental and bioinformatic analysis approaches have been used to investigate the relationship between inhibition of the repair of abasic sites in DNA by MX, a synthetic molecule designed to inhibt the repair activity of APE1, and the modulation of the inflammatory response. The results showed that treatment of monocytes with lipopolysaccharide (LPS) and MX reduced the expression of cytokines, chemokines and toll-like receptors, and negatively regulated biological immune processes, as macrophages activation, and NF-κB and tumor necrosis factor (TNF-α) and interferon pathways, without inducing cell death. The transcriptomic analysis suggests that LPS/MX treatment induces mitochondrial dysfunction, endoplasmic reticulum stress and activation of autophagy pathways, probably activated by impairment of cellular energy and/or the accumulation of nuclear and mitochondria DNA damage. Additionally, it is proposed that the repair activity of APE1 is required for transcription of inflammatory genes by interaction with abasic sites at specific promoters and recruitment of transcriptional complexes during inflammatory signaling. This work presents a new perspective on the interactions between the BER activity and the modulation of inflammatory response, and suggests a new activity for APE1 protein as modulator of the immune response in a redox-independent manner.

Uma abordagem para avaliação e tratamento de exceções propagadas no uso de serviços Web em .Net

High dependability, availability and fault-tolerance are open problems in Service-Oriented Architecture (SOA). The possibility of generating software applications by integrating services from heterogeneous domains, in a reliable way, makes worthwhile to face the challenges inherent to this paradigm. In order to ensure quality in service compositions, some research efforts propose the adoption of verification techniques to identify and correct errors. In this context, exception handling is a powerful mechanism to increase SOA quality. Several research works are concerned with mechanisms for exception propagation on web services, implemented in many languages and frameworks. However, to the extent of our knowledge, no works found evaluates these mechanisms in SOA with regard to the .NET framework. The main contribution of this paper is to evaluate and to propose exception propagation mechanisms in SOA to applications developed within the .NET framework. In this direction, this work: (i)extends a previous study, showing the need to propose a solution to the exception propagation in SOA to applications developed in .NET, and (ii) show a solution, based in model obtained from the results found in (i) and that will be applied in real cases through of faults injections and AOP techniques.

Processos criativos com alunos-atores idosos: caminhos de uma dramaturgia de pertencimento

The present work is to present an experience artistic and pedagogical means of a laboratory-developed with senescent students from their memory files. Unlike other works developed with students of the third age, we make use of the archives of memory, where the drama takes from improvisations developed memories, in other words, the text is built not just recollected by students. Our work, however, is built by a look from the outside. The affective memories narrated by students serve as an engine for text construction and spectacle titled Vamos Falar de Amor. In this experiment the teacher-director also becomes an dramaturgista, and uses her imagination, that also comes filled with her own memories, in order to complete the gaps of the narrative, in a hybrid process in which the collective memory interlace the individual memory, transforming epic into dramatic. Here the route designed to get to the construction of the text and left the text for the second scripture, the spectacle. We want to show that old age is comprised of various hues, and that this phase of human development brings aspects that differ from old to old, and that education and theater can be a resumption of the social role of the elderly in contemporary surroundings. Therefore, the dramaturgy of memory creates the dramaturgy of belonging, facilitating in many aspects the Scenic Play with the elderly ones.

Efeito agudo do exercício físico associado a praxias ideomotoras sobre as concentrações séricas de cortisol e memória declarativa em indivíduos com idade entre 51 e 74 anos

Introduction: Several modifications are identified as aging, causing more or less limitation imposed by over the years. Among these, one can highlight the different degrees of cognitive decline, particularly memory that can involve the daily activities and the subject functionality. Studies have shown an association between levels of serum cortisol and stress imposed by the exercise on this. However, there are few studies that references the performance on cognitive aspects of declarative memory and cortisol on the exercise in the water with automatic and práxicos movements and moderate. Objective: Check the effect based on the acute physical exercise and práxicos automatic movements on the performance of visual declarative memory and in serum cortisol in subjects aged between 51 and 74 years. Materials and Methods: It builds a survey characterized as cross with a first sample of 32 physically active subjects aged between 51 and 74 years, divided into two exercise groups (March of Automatic Group - MAG and the March of Praxis Group - MPG). We used a probabilistic and random sampling for sample selection. Used the MMSE (Mini Mental State Examination) to check the general cognitive status, visual acuity test - optotypes chart "E" Rasquin and was even used the declarative visual memory test proposed by Nitrini and collaborators (1994), applying before motor stimulation and immediately after, and the day of blood collection with 2 ml for analysis of cortisol hormone. The normality and homogeneity were verified from the Shapiro-Wilk and Levene tests. Thus we adopted a descriptive statistics to characterize the sample. The Split-Plot ANOVA was used along with the paired t-test to verify the identified differences. We adopted a significance level of p <0.05. Results: It was observed that the groups (MAG and MPG) and the anthropometric variables, perceived exertion, education, cognitive assessment and visual acuity showed no significant differences (p > 0.05), showing that the groups are homogeneous, with variables and similar means. After the stimulation session, lasting 30 min, it was observed that the amount of hits for Δ of declarative memory questionnaire visual images increased, presenting significant for both groups (MAG, p < 0.001; MPG, p = 0.042). The same was observed for cortisol concentration with a reduction in the levels immediately after the stimulus (MAG and MPG, p < 0.001). Conclusion: The results showed that the exercises proposed in its acute effect provide significantly memories of gains and also showed a reduction in cortisol levels.

Mestrado profissional em saúde da família: o curso sob a perspectiva dos mestrandos

Professional masters were created in Brazil in the 1990s in response to social changes in the world of work and aim to train high-level professionals with own profile for various activities of society and the productive sector. They are up in more innovative mode of graduate studies in Brazil, and therefore lack of legitimacy of their identity, which raises the need for discussions to get further information and outline the characteristics of this postgraduate modality. You want to build new understandings about their peculiarities starting from the perspective of students from the Professional Masters in Health Net Northeast Family Training in Family Health, and not only according to the similarities and differences with the academic master. This study aims to understand the meanings attributed by masters training in that course. This is a qualitative, exploratory study. The subjects are 100 students in training in 2013, distributed among the six institutions nucleation Network Northeast Training in Family Health. To collect information desk research was conducted in institutional records of all students, as well as interviews. We interviewed 15 students, distributed in the six nucleation institutions. Information obtained through recorded interviews were transcribed and resulted in two analytical corpus subsequently submitted to Alceste © 4.9 software for identification of semantic classes. It can be concluded that the course provided a redefinition of professional practices in the Family Health Strategy, considering the organizational context of primary care in the Northeast and the specifics of the health work. Even before the student body difficulties related to ownership of research methods, and the very active methodology of problem-based learning, the course effectively contributed to the improvement of work processes in primary care, valuing teamwork and allowing the acquisition of new scientific knowledge.

Classificação de técnicas e auxílio à navegação de busca com base em sua carga cognitiva, precisão e eficiência

Navigation, in both virtual and real environments, is the process of a deliberated movement to a specific place that is usually away from the origin point, and that cannot be perceived from it. Navigation aid techniques (TANs) have as their main objective help finding a path through a virtual environment to a desired location and, are widely used because they ease the navigation on these unknown environments. Tools like maps, GPS (Global Positioning System) or even oral instructions are real world examples of TAN usage. Most of the works which propose new TANs for virtual environments aim to analyze their impact in efficiency gain on navigation tasks from a known place to an unknown place. However, such papers tend to ignore the effect caused by a TAN usage over the route knowledge acquisition process, which is important on virtual to real training transfer, for example. Based on a user study, it was possible to confirm that TANs with different strategies affects the performance of search tasks differently and that the efficiency of the help provided by a TAN is not inversely related to the cognitive load of the technique’s aids. A technique classification formula was created. This formula utilizes three factors instead of only efficiency. The experiment’s data were applied to the formula and we obtained a better refinement of help level provided by TANs.

Análise de métodos para detecção de mudanças estruturais em séries temporais climáticas

The time series analysis has played an increasingly important role in weather and climate studies. The success of these studies depends crucially on the knowledge of the quality of climate data such as, for instance, air temperature and rainfall data. For this reason, one of the main challenges for the researchers in this field is to obtain homogeneous series. A time series of climate data is considered homogeneous when the values of the observed data can change only due to climatic factors, i.e., without any interference from external non-climatic factors. Such non-climatic factors may produce undesirable effects in the time series, as unrealistic homogeneity breaks, trends and jumps. In the present work it was investigated climatic time series for the city of Natal, RN, namely air temperature and rainfall time series, for the period spanning from 1961 to 2012. The main purpose was to carry out an analysis in order to check the occurrence of homogeneity breaks or trends in the series under investigation. To this purpose, it was applied some basic statistical procedures, such as normality and independence tests. The occurrence of trends was investigated by linear regression analysis, as well as by the Spearman and Mann-Kendall tests. The homogeneity was investigated by the SNHT, as well as by the Easterling-Peterson and Mann-Whitney-Pettit tests. Analyzes with respect to normality showed divergence in their results. The von Neumann ratio test showed that in the case of the air temperature series the data are not independent and identically distributed (iid), whereas for the rainfall series the data are iid. According to the applied testings, both series display trends. The mean air temperature series displays an increasing trend, whereas the rainfall series shows an decreasing trend. Finally, the homogeneity tests revealed that all series under investigations present inhomogeneities, although they breaks depend on the applied test. In summary, the results showed that the chosen techniques may be applied in order to verify how well the studied time series are characterized. Therefore, these results should be used as a guide for further investigations about the statistical climatology of Natal or even of any other place.

Repercussão da integração de conteúdos das disciplinas nos trabalhos finais de graduação de CAU-UFRN (2003 a 2010)

The changes in the teaching of Architecture in Brazilian Universities, from the 1990s onwards, with the upgrading of the Architecture project as an object of research and scientific knowledge and more specifically, the adoption by the Architecture and Urbanism Course (CAU) from the Federal University of Rio Grande do Norte (UFRN) of the principle of content integration of the disciplines, aroused the interest in research on issues related to the Design process and the teaching of design in this context. After 20 years of its implementation and recognized as being a major step forward in teaching the teaching/learning process, the integration is the central focus of this research, which will seek to identify changes in the teaching design and its refutation in projects developed by students at the end of their course. In general, it is understood that the need to integrate knowledge from diverse areas of Architect’s professional activity, who seeks through an exercise of summary, identify solutions to the issues involved in a project. On the assumption that the integration of content of disciplines fosters the teaching/learning of Architecture project, which can be evident in the Final Course Assignment (FCA), it becomes necessary to understand, in the light of theories of education, such as the principles of curriculum organization, such as interdisciplinarity and multidisciplinarity, transdisciplinarity and transversality are related to the term integration, is more understood and disseminated among the professors of the Architecture courses. The object of this study is consequently the relationship between the integration of subject content and Architecture projects developed by students from CAU-UFRN, in the context of Final Graduation projects (FCAs) completed in the period of duration of the Teaching Project A5-from 2003. The study has the main objective of investigating to what extent the integration of disciplinary content affects the development of the Final Assignment of UFRN, from the analysis of drawings and texts of the projects of the learners and the testimonies of teachers and undergraduate students. From a methodological point of view, the research “Architecture, Project and Knowledge Production: Academic Production – FCAs, Thesis and dissertations in PA/Brazil” carried out by the PROJETAR/UFRN team has been adopted as the basis for the construction of the analytical instruments. In order to identify aspects of their experience by various actors which were not recorded in FCA, electronic forms were applied between teachers and students, through the internet. The integration of subject content based Teaching Project of CAU-UFRN institutionalises the interdisciplinarity, organizing the curriculum by thematic semesters, in which the disciplines work the same focus and at the same site. The integrated work which derives from there tries to articulate the content of each discipline of the period and represents a general practice and has been evaluated by teachers and students, and considered as a facilitator of the teaching/learning process. The analysis of the data collected from the textual content and graphic of the sample of FCAs of CAU-UFRN suggests that the content of the various areas of knowledge are assimilated by the student and used as a resource for the design and development of Architecture projects. In other words, there is in the end product of the students record of the integration of content, whether in speech or in drawing, reaffirming the importance of the convergence of various knowledge in the Architectonic project. However, the integration of content from the point of view of their articulation and operationalization, which involves teachers and students in the same period, has as a condition sine qua non for the success of this educational principle, the provision of these to work as part of a team, for the dialogic practice, which creates areas of intersection not only between disciplines, but between the knowledge of each of the participants.

Releituras de Celso Furtado: Brasil (2001-2012)

Seeking to explain the causes leading to the developme nt and attempt to understand it, some economists were organized around central ideas, culminating therefore in the development of economic theories. The knowledge accumulated over the work by these scholars will make a significant contribution in shaping t he thinking of Celso Monteiro Furtado . Furtado developed numerous studies trying to understand the dynamics of underdeveloped structures, what their basic characteristics and the main factors responsible for the perpetuation of the status quo of these stru ctures. Starting from the question "What remains of underdevelopment characteristics in Brazil in the light of the thought of Celso Furtado?", This work is guided by the hypothesis that Brazil has not suffered between 2001 and 2012, significant structural changes that it could classifies it as a developed country. It has been for this work as a general objective to analyze the underdevelopment of elements that persist in Brazil in the light of the thought of Furtado. And as specific, characterize economic d evelopment, from the study of the classical schools, Marxist, neoclassical, Kaleckian, Keynesian and ECLAC of economic thought; describe the economic underdevelopment in light of Celso Furtado ideas; and, finally, evaluate from the particular epistemology of thought Furtado Brazilian economic reality, with emphasis on the analysis of underdevelopment elements. It was found that although there have been important advances in some sectors, the country maintains a significant structural heterogeneity. Hence th e relevance of Furtado's contribution to understanding the economic underdevelopment, because he is still a constant in our reality.

Atuações e papéis femininos: o corpo a corpo da atriz no teatro pernambucano durante a ditadura militar

This research investigated the female performance in Pernambuco theater during the Brazilian military dictator ship in the 1970s, analyzing the works of four actresses of theater groups Hermilo Borba Filho, Experiential and Expression, who acted in the period. Launches a look at the female body in the theater from a body scenic transgression: the conscience of a body insubordination in response to a given context. However, before delineated an overview of the artistic and socio - cultural position of women in the theater, in the periods prior to the dictatorship in Brazil and Pernambuco, covering theatrical and historical references, in order to reflect on how these settings interfered in the picture Social actr ess under the dictatorship. The groups are revisited by the looks of interpreters, which was perceived that female targeted search relationships, and in this context, relations with other theater groups of the time, with other artists of the groups that we re inserted with the dictatorial context with censorship, with the offender engaged and theater, with the body. In parallel, it develops a reflection on the scenic body that opposed the dictatorship, a body that violates the established norms, the Transgre ssor Body. The research also discusses an analogy between the work of the actresses who opposed the military regime and militant women. Starting from analyzes with interviews with the actresses from the methodologies of Oral History and Discourse Analysis, the study is developed by building up connections between the testimonies of the artists and the philosophical assumptions of Henri Bergson, on the body and memory. It is also designed to reflect on the changes of the female body in the theater in history , also in line with the philosophical concept of Becoming Woman Felix Guattari. It was found, therefore, that the actresses from the nineteenth century, were a group of female social actors who changed the position of women in history; the stigmatization o f the actress by profession, considered indecent in previous centuries, left traces in some areas today and the idea of the liberation of the female body propagated by feminism in the 1970s, was configured at the time as the best way to protest and will influence, in some contexts, the representation of women in their theatrical make.

A escrita no Ensino Fundamental II: uma análise dos desvios ortográficos e sugestões de estratégias de intervenção

This paper presents a reflection on the written language, a social practice that is increasingly strengthened in everyday life. Unveiling its nature, organization and function must be the first step for teachers to change their posture towards the teaching of this linguistic mode, helping students use it more effectively and securely. Considering these principles, this dissertation seeks to understand on the light of contemporary linguistic theories, the factors that influence the writing deviations were found in the text production of students of the 8th grade of elementary school II, enrolled in a public school in Rio Grande do Norte, whereas those deviations reveal the beginning of learning of this communication tool, representing the first hypotheses raised by students to dominate it. To analyze the data we used the works done by Lemle (1995), Cagliari (2009), Carraher (1985), Zorzi (1998), Guimarães (2005), Miller (2008), Veçossi (2010), among others, starting from of which, the scientific production on reading and writing learning come developing. The results of this analysis showed that the writing deviations present in the texts of the students are motivated not only by lack of knowledge of standard orthographic of the Portuguese language, but, also, stem from phonetic, phonological and grammatical factors. Thus, we seek to present new teaching and learning strategies of writing that might lead students to reflect on the use of the same, developing this ability more critically and creatively. We believe that the activities presented can minimize writing with orthographic deviations or linguistic variation practiced by students. Keywords: Variances writing, spelling, teaching strategies and students

Proposta de jogo químico como estratégia didática no ensino a distância abordando o conteúdo de estereoquímica

The educational games can act as a complementary tool in the teaching and learning as play an important role in the interaction of the student with knowledge, and encourage interrelationship between students and motivate them by the pursuit of knowledge. This research is intended to analyze the evidence of the students of distance education applied to semesters 2011.2 and 2012.2 for the purpose of to catalog the mistakes presented by the students, the contents of stereochemistry that attended the Chemistry of Life discipline. From the presented mistekes, develop an educational game, "walking the stereochemistry", addressing that content. The choice of stereochemistry content was due to the low number of found work in the literature, and for being one of organic chemistry content that generates learning difficulties, as it requires a mental visualization and manipulation of molecular structures, besides require observation and comparison ability by the students. The game was applied of Life Chemistry discipline of Nova Cruz Polo in semester 2013.2, with intention to verify the viability and applicability this tool for the development of motivation ability by the pursuit of knowledge by the students, as well as complement the didactical materials of the DE. Then, It was made available on the course page an opinion questionnaire to the participants of the game, as a way of to investigate the opinion their about the proposed strategy. To diagnose the contributions of the game on student learning, it was taken a comparative analysis of stereochemistry issues contained in didactic tests applied in 2013.2 semester students participating and not participating of the polo of Nova Cruz and was also compared with the tests applied at the poles of Extremoz, Currais Novos, Lajes and Caico. So the game can be considered an important resource to complement the teaching materials of distance education, because awoke the motivation for the search of knowledge and contributes to the learning of stereochemistry content.

A escrita no ensino fundamental II: uma análise dos desvios ortográficos e sugestões de estratégias de intervenção

Why students of 6th year still present oral marks in written? To answer this question our paper presents what they are and how writing and grammatical deviations occur and emerged in an attempt to expand on these studies. The same objective to evaluate the presence of these deviations in genres produced by students of the 6th year of the Municipal School Manoel Catarino Filho and check if there are more variation deviations or grammatical deviations. It also aims to improve the linguistic and discursive ability of students in various traffic environments of certain genres and consequently the formation of active readers and writers. In order to better understand how this process occurs, the text starts of the socio discursive conception of gender, with the theoretical background studies of Bakhtin (1992) and Marcuschi (2002) about this conception and the rhetoric conception of Aristoteles and Platão. The text underlies even the works of Callou (2007), Neves (2003), Faraco (2002), Franchi (2006) and Cagliari (2005) on the Grammar School, linguistic variation as also on the sociolinguistic parameters as well in research on the phonetics and phonology of Oliveira e Nascimento (1990), Seara (2009), Hora (2009) and in the PCN. To compose the corpus of this study we collected 23 texts produced by students to serve as a data source for analysis of the presented deviations by quantitative and qualitative research method, in which categorize the deviations found in two groups: oral and linguistic variation deviations and writing and grammar deviations. The results showed that there was a rate of occurrence of oral and variation deviations greater of writing and grammar deviations. We concluded that the orality has a great influence on the written production of students. Finally, we propose some activities aimed at minimizing the occurrence of deviations in written productions of the students.

O slogan empresarial como construção discursiva: uma abordagem cognitivo-funcional

In this paper, we analyze corporate slogans, understanding them as a discursive construction that is, as a pairing of form and function able to unite the notions of textual type and discursive genre. In this way, we developed a qualitative and quantitative analysis, aimed specifically to analyze the formal properties (phonetic, morphological and syntactic) and functional (semantic, pragmatic and discursive) of slogans. Furthermore, we attempted at verifying and quantifying recurring aspects involved in their construction, in order to capture configurational patterns underlying their formation. The data come from slogans collected in products and / or service stores in the metropolitan area of Natal city, Rio Grande do Norte. This research is based on the Cognitive-Functional Linguistics, that conjugates the North American functionalist tradition, represented by researchers as Talmy Givón, Paul Hopper, Joan Bybee, Elizabeth Closs-Traugott, with Cognitive Linguistics, in particular, the chain linked to Construction Grammar, as postulated by Adele Goldberg, William Croft e Jan-Olla Östman, among others. The results ratified the importance of the interface between the formal and functional aspects in the analysis of linguistic uses. These results point to the idea of the slogan as the pairing of form and function on textual / discursive level, in other words, as a discursive construction, constituting as cognitive storage of a scheme / model of textual formation with a specific discursive-pragmatic function.
