Objective: This study aimed to investigate the contribution of sports activities for children participating in social programs. Method: It s dealt with in a survey of a descriptive nature. The sample was composed of 51 participants from the Project Nova Descoberta, ranging in ages from 8 to 17, males (n=29) and females (n=22). A semi-directed interview was applied with 10 items over a period of 2 consecutive years (2007-2008) with children and adolescents, besides obtaining documental data in the schools that have an agreement with the Project. Results: The performance of the participants in the groups that joined and did not join in terms of schoolwork production in the year 2007 did not present statistical differences (p<0,05). A significant difference (p<0,05) was observed in the discipline of Portuguese when compared between the groups, with a higher average for the students who joined in 2008. Discussion: In the face of the context found in social sports projects, emerges a series of indicators that contribute for a reliable evaluation. The manifestation of other characteristics in the environment could be interfering in the participation and involvement in physical activity and consequently in the health and quality of life situation of the children and adolescents. Conclusion: It was confirmed that the school work performance indicators can be taken together with other indicators, such as a development of various abilities, participation in other activities, motivation for the activities, behavior and attitudes at home and at school, for evaluation of social projects

Resolutions of the Board of numbers 359 and 360, of December 23, 2003, relating to Nutrition Labelling for Packaged Foods, establish quality standards and provide the education activities for health consumption, since one of the factors that enable the selection of healthier foods are the food labels as an important part in nutrition education. This is a descriptive study with a cross-sectional design. To calculate sample size, it was considered a margin of error of 20%, confidence level of 95% and prevalence of 52.5% for verifying nutritional information in a pilot study conducted in 2007. A total of 145 subjects were interviewed, resulting in 371 consumers in Natal, Rio Grande do Norte, Brazil, in order to determine prevalence of consulting nutritional information contained on food labels as a nutritional guideline for consumers and its association with sociodemographic variables as well as identify the intervention measures suggested by intervieweds so that this information can be better used to select healthy foods. Twenty-five of the 69 supermarkets belonging to the Supermarket Association of Rio Grande do Norte (ASSURN) were randomly selected. Data collection relied on interviews and extensive direct observation, using a semi-structured form composed of eight closed questions, some of which were multiple choice, and ten open questions. The chi-square test was performed for statistical analysis, using Statistical Package for Social Sciences (SPSS) 15.0 software. Label information most consulted was: expiry date (91.6%); product brand (49.4%); nutritional information (47.0%); zero trans fat (32.9%); zero sugar content (12.8%); zero fat content (3.0%); rich in fibers (2.7%); whether light or diet (30.4%); list of ingredients (16.8%); whether the product contained gluten or not (4.1%). When asked about the importance of nutritional information, 96.8% of the subjects responded important or very important ; of these 46.6% and 3.8% reported partially or totally understanding the information presented. It was found that 41.6% of the consumers consulted nutritional information for dietary reasons related to nontransmissible chronic diseases and 35.7% to be able to choose healthier foods. The data show a significant association between motivation to choose healthier foods and higher family income and schooling (p<0.0001). The intervention measures mentioned to make nutritional information better understood and used were: information and orientation about nutritional information, provided by qualified professionals in the supermarkets, the commercial establishment or the product manufacturer (73.9%) and media disclosure about the nature, importance and purpose of nutritional information (42.9%). In despite of communication noises the consumers use the nutrition claim for the nutritional guidance, showing association with some demographic variables. However, they desire the implementation of intervention measures that can be contextualized in the political construction of nutrition education to promote healthy food choices

Recent years have seen a significant growth in surface modifications in titanium implants, resulting in shorter healing times in regions with low bone density. Among the different techniques, subtraction by chemical agents to increase oxidation has been applied for surface treatment of dental implants. However, this technique is generally unable to remove undesirable oxides, formed spontaneously during machining of titanium parts, raising costs due to additional decontamination stages. In order to solve this problem, the present study used plasma as an energy source to both remove these oxides and oxidize the titanium surface. In this respect, Ti disks were treated by hollow cathode discharge, using a variable DC power supply and vacuum system. Samples were previously submitted to a cleaning process using an atmosphere of Ar, H2 and a mixture of both, for 20 and 60 min. The most efficient cleaning condition was used for oxidation in a mixture of argon (60%) and oxygen (40%) until reaching a pressure of 2.2 mbar for 60 min at 500°C. Surfaces were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), atomic force microscopy (AFM), adhesion and cell proliferation. SEM showed less cell spreading and a larger number of projections orfilopodia in the treated samples compared to the control sample. AFM revealed surface defects in the treated samples, with varied geometry between peaks and valleys. Biological assays showed no significant difference in cell adhesion between treated surfaces and the control. With respect to cell proliferation, the treated surface exhibited improved performance when compared to the control sample. We concluded that the process was efficient in removing primary oxides as well as in oxidizing titanium surfaces

Objective- Convinced that periodontium, many times, can show alterations in human health, the aim of these studies was to investigate the periodontal situation in patients with endocrine-metabolic disorders such as, Berardinelli-Seip Syndrome, hyperthyroidism, hypothyroidism and acromegaly. Methods- Eight patients with Berardinelli-Seip Syndrome, 16 acromegalics, 30 hypothyroids, 30 hyperthyroids, and a control group with 35 patients were evaluated. Clinical attachment loss, probing depth, gingival bleeding index, gingival overgrowth and Index of Decayed, Missing and Filled Teeth were measured in each patient. All ethical aspects were rigidly observed, being the study conducted after its approval by the University of Fortaleza Research Ethics Committee. Results- The presence of periodontitis was marked in hyperthyroids and in patients with Berardinelli-Seip Syndrome. Hypothyroids showed not much presence of periodontitis, while all acromegalics presented absence of periodontitis. Conclusions- The protective effect of periodontitis in acromegalic patients is a new finding, whose mechanisms are not yet clear, but may be related to the anabolic effects of growth hormone. The presence of periodontitis in Berardinelli-Seip Syndrome may occur due the early onset of diabetes. In hyperthyroids, the high prevalence of periodontitis could be linked to thyroid hormones effects on bone, explaining also the minor prevalence in hypothyroids

Objectives: The purpose of the current study was to diagnose military police officers in Natal, Brazil as to the level and phase of stress in which they find themselves and the prevalent symptomatology (physical or mental). Methodology: Descriptive, crosscut study that investigated a sample of 264 individuals taken from a population of 3,193 military police officers of the Capital Police Command (CPC) in Natal, Brazil. The data were collected using the Lipp Stress Symptoms for Adults Inventory LSSI, and analyzed by tabulations, percentage calculations, t-test for proportions and Pearson s chi-squared test for associations between stress, symptomatology and military rank. Data collection was between June/2004 and January/2005. Results: It was found that 52.6% of the officers had symptoms of stress and 47.4% symptomatology of stress. This was distributed across all ranks, especially mid and upper-level officers as well as corporals and privates, with predominance in the resistance phase (36%) and a prevalence of psychological symptoms (76%). The only variable investigated that was related to stress was gender (P = 0.0337). Conclusions: It was concluded that there is stress among all ranks of military police officers in Natal, Brazil, especially mid and upper-level officers, corporals and privates, with a prevalence of psychological symptoms, low levels of physical symptoms and predominance in the resistance phase. It seems that stress levels do not differ significantly from those found in Brazilian men and women and do not indicate a situation of chronic fatigue

This study reflects on the conflicts that exist between the different forms of participation and the political representation manifested by community organizations and social movements in the city of Natal/RN. The objective is to better understand the process of political participation of the popular classes and how the different actors have represented collective demands in the struggle for rights. To this end, we mapped the organizations, social movements and participation spaces, through a type of participant research, in which we had the opportunity to experience and study different forms of collective action and events instigated by the community organizations and the Movement for the Struggle in the Neighborhoods, Villages and Slums (Movimento de Luta nos Bairros, Vilas e Favelas) MLB. From the theoretical contributions of authors such as Maria da Glória Gohn, Marco Aurélio Nogueira, Virginia Fontes, Vera da Silva Telles, Roberto Da Matta and Carlos Montaño, as well as the empirical data collected, the study revealed that on representing their segments and occupying different spaces of participation, some actors have formed partnerships with the State, putting collective demands on a second plane. Contrarily, other actors have articulated their struggle around collective demands and manifested through direct action, mobilizing and asserting themselves in defense of a project for society

This report has as its objective the setting up of a social cartography, mapping and characterizing non-governmental organizations working with adolescents and young people (OSC) in the western districts of the city of Natal. Characteristics such as the profile, themes and principal activities, how the organizations fit into the public sector and their participation in social networks are observed. Thus common differences and similarities which serve as a means of indentification, take as reference the symbolic cartography of Boaventura of Sousa Santos. Since there are relatively few studies relating to civil society of Rio Grande do Norte and in particular, Natal, the starting point was the setting up of a database allowing for a general overview. Hence a panorama of the organizations could be observed: where they are located, when they were formed how they operate and their relationships with other sectors (the state, the market and civil society) in addition to basic facts and location. The principal lines of enquiry were a) the OSC which operate with the public comprising adolescents and young people and b) the OSC operating or having branches in four suburbs on the periphery of the western administrative region of the city (Felipe Camarão, Bom Pastor, Cidade Nova and Guararapes).The present report has identified the impacts of ongoing social transformation caused by the process of globalization ,by the various currently contested political projects which are as follows: the project of neoliberal globalized capitalism(hegemonic)and the project of social emancipation (contra-hegemonic),how these are seen from the local viewpoint and how they influence the profiles and operation of the cartographic organizations. The area of the OSC is a heterogenous one with political, cultural and ideological strains, characterized by its infiltration, its local/global and multicultural dimensions. As civil organizations are fundamental in the processes of transformation within society, and following the idea of social emancipation referred to by Boaventura Santos, the enquiry classified the organizations according to the afore-mentioned characteristics, establishing eight types of associations. These different types and their respective characteristics were analysed from a related perspective using the mechanisms of symbolic cartography: scale, projection and symbolisation. The theoretical references underpinning this research arise from the debate on civil society which becomes redefined as a result of the dispute involving the two afore-mentioned political projects. These demand the theoretical application of the comprehension of heterogeneity in its diversity and complexity together with the idea of social emancipation.The main authors consulted were Boaventura de Sousa Santos, Antonio Gramsci, through the texts translated by Marco Aurelio Nogueira; Carlos Nelson Coutinho and Alberto Rivera ,who supported the construction of the types of associations identified by the local reality.Finally this research enabled an understanding of the current form of social action happening in the Space of the Four Neighbourhoods (Espaço dos 4 Bairros) and how the distinct profiles analysed together with the ares of operation of the organizations define their emancipatory potencials within the following two poles: regulation/adaptation and emancipation/transformation

This paper focuses on a study of public policy jurisdictional control as some effectiveness mechanism for cultural, economical, and social fundamental rights. It investigates the juridical profile of public policies based on premises of the current (Neo)Constitutional State model and the assertion of an essentially constitutionalist Law paradigm from its genesis to its most peculiar elements, and through tormenting issues, such as: its position between Law and Politics, the difference with reflective subjective rights, and the problem of high financial costs. Once its object is identified, it moves forward into the theme itself, which is that of jurisdictional control, investigating its legitimacy based on paradigmatic judicial precedents and the facing of themes such as: current role of the Judicial Power, the splitting of state functions, administrative discretion, financial affordability, illegal omissions, and budget control. Finally, it examines, as its study central object, objective parameters for definition control, execution, and transparency of public policies, as well as identifying the most appropriate collective jurisdictional tutoring to its purposes together with some of its law process means. Therefrom, it shows new perspectives for the recent study on jurisdictional control of public policies, building foundations for the fundamental rights effectiveness

This work has contributed to knowledge of the order Testudines from cytogenetic and morphological point of view. With regard to the aspects proposed cytogenetic characterization of the species Mesoclemmys tuberculata (n = 5), endemic to the Caatinga biomes, through conventional techniques of cytogenetics and molecular levels. This species presented 2n = 58, NF = 64, the first submetacentric pair, the second metacentric and third subtelocentric, and the other microchromosome telocentric. This species showed a nucleolar bearing pair, coincident with the 18S ribosomal rDNA and that proved to be heterochromatic. Small heterochromatic blocks were also found in the centromeres of the largest chromosomes, as well as terminal regions in most other chromosomes of the complement, that were GC +. Telomeric sequences showed variable patterns of signal intensity, with some repeats more intense in microchromosomes and subtly in the larger ones. When compared with other species of the genus, the G-banding patterns showed a marked similarity between them. The first karyotypic description of the species will aid in future studies and the understanding of evolutionary aspects of this family. From the morphological point of view, we carried out studies of fluctuating asymmetry in sea turtle Eretmochelys imbricata, using methods of benchmarking between hatchlings and adults and their implications for natural selection. Data were collected at two different times: first during the spawning female and the second during the outbreak and birth of the nest. The analyzed characteristics consisted of measurements of length and width of front and rear flippers (CANT, LANT, CPOS and LPOS) also collected data on the number of hull plates, side plates (NPL), the surrounding plates (NPCIRC), and plastron; plates power plants (NPP), inframarginais plates (NPIM). With the values of asymmetry we calculated the value of strict heritability for these traits, the calculation was based on only one parent. A nonparametric analysis Mann-Whitneywas performed to compare the groups (females X hatchlings, newborn hatchlings X dead hatchlings). Adult females showed no bilateral fluctuating asymmetry (FA = 0) on the number plates of the hull and plastron, while offspring, living and dead, showed a greater level of variation in these meristic parameters. In the analysis of females x hatchlings we found a significant difference between the levels of asymmetry in hoof plates (p=0.006) an the width of hindlimbs (p=0.001). Levels of FA suggest an accurate indicator as to the viability or maintenance of the individual to the reproductive phase. The coefficient of heritability (h2) of FA , obtained from the regression analysis, showed that both have low and not statistically significant values(p> 0.1). In the case of exclusion of the effective role of genetics in the generation of FA, reproductive strategies based on high number of subsidiaries products, such as those observed in E. imbricata seems to implicate the production of individuals with high level of developmental instability

The Nossa Senhora da Conceição Seminary, installed in 1894, by Dom Adauto Aurélio de Miranda Henriques, first Paraíba Bishop, and the Episcopal Seminary of the Sagrado Coração de Jesus, implanted in 1913, by Dom José Thomas Gomes da Silva, first Aracaju s Bishop diocese, were created as a result of lack of an official religious process proposed by the Brazilian Republic Proclamation, in 1889. With the appoint to enlarge the number of priests and change the image of the priest married and unrolled who used to identify the Catholic Church in the colonial and imperial Brazil. Such bishops developed into intellectuals in the government, dioceses and formation priest houses. I take as a study object, for this doctorate paper, the academic formation and priesthood developed in theses seminaries, from 1894 to 1933, once 1894 the year of João Pessoa Creation Seminar that was implied the Minor Course (preparation) and the Major one (built by Philosophy and God related studies) and the research limit year of 1933, is concerned about the Major Sergipe Seminary ending, which was created and has worked offering the Minor and Major courses, from 1913 to 1933. Showing the teaching models that guided and leaded the priest formation, referred as Seminaries, and the application result is the objective of this investigation. To comprehend the teaching models seminaries studied, my research line is the Catholic Church theme and priest formation in Brazil. In front of the object and the objective desired, I chose the historical comparative method and the scholars modals notions of Araujo de Barros (2004) and the Sirinelli intellectuals (1996). Such references allowed me to analyze the formation given in the seminary and seminarian participation and actions, included the sequence after the scholars formation. The thesis defended is that the teaching model developed in the Brazilian Seminaries, created after a non official religious process in the Brazilian government, deal with a model of one unique center (Seminary formation and aim pre arranged by Santa Sé), although adapted, presuming the local reality and formation structure (privileged not only spiritual and moral speaking, but intellectual also), was it responsible for intellectuals generations (teachers priests, educationalist priest, journalists priests and so on) that boost the education in Brazil. During the Republic first three decades, when, in thesis, the Government was becoming free religion, i.e., the government did not subsidize the Church anymore, and the Government, among others aspects, did not received any Church care to help the public teaching in the country. The investigation reveled accede, by bishops and their followers, such as by the Concílio de Trento pre concept, or by the others ideas, leading by the priests formation in Seminaries. By creating and stalling diocese Seminary, Bishop Dom Adauto and Dom José went further their functions, by the time they built inside themselves a teaching model thought from the main pedagogic logic, based on several religious exercises, moral and ethic, considered by themselves several knowledge connected to humanity, philosophy and God related studies). Following clearly rationalism principle (the way of teaching, which each subject has its own teacher and this class get together students with the same knowledge, regardless of age) and efficiency (trying to teach the whole content in each class), the Seminaries researched developed a whole education, allowed the structure of a spiritual education, moral and intellectual, for a quality developed by priests, including different levels that they used to performance. Their bottom line, actions and priest matter achievement allowed their broad fulfillment, in the way that priests matter were associated with cultural, educational, welfare assistance, at last, intellectuals

This project goes beyond the interfacial field of cinema, History and education. We take as our object the epistemological potential of the cinema at the educational scenario, specifically the use of films integrated to the practices of History teachers and educative processes in which we have taken part as a builder. Our objective is to map, initially, the knowledge around this use to search a synthesis and its empirical application. From the methodological point of view, we have made use of different perspectives: (a) interviews with the educator subjects; (b) observation of their practices and formative circumstances; (c) filmic analysis and the relation of the cinema s epistemology with the other areas ones (initially History and further Journalism). Our analysis allowed us to portrait the film such as an epistemological-troubling category, what makes the cinema rather a builder technology and not simply a complementary and illustrative technological resource. Therefore, we have realized that the restriction to the cinema s educational function is linked to the restrictions to the theoretical categories to an only interfacial aspect: historical film as a film which portraits the past (at the historical field) and film on journalism as a film which approaches a single object of Journalism (at the journalistic field). These discussions happen, consequently, at the arena of the nature of cinema s genres (fiction and documentary), which are understood in a naïve way, simpler than its epistemological possibilities, boosted at this research when we analyze the confluence between fiction and reality. The reflections on educative practices and in formation related to the cinema had occurred in three empirical realities: research with professors in performance, practices docent s and accompaniment of students of history. Have to do with our personal career as a teacher and researcher and, when analyzed other practices, have become, unavoidably, the subject and object of this project

In this study were conducted experimental procedures for determination of variation of the expandability of rigid polyurethane foam (PUR) from a natural oil polyol (NOP), specifically the Castor oil plant, Ricinus communis, pure and additions of the vermiculite in phase dispersed in different percentage within a range from 0% to 20%, mass replacement. From the information acquired, were defined the parameters for production of bodies of test, plates obtained through controlled expansion, with the final volume fixed. Initially, the plates were subjected to thermal performance tests and evaluated the temperature profiles, to later be extracted samples duly prepared in accordance with the conditions required for each test. Was proceeded then the measurement of the coefficient of thermal conductivity, volumetric capacity heat and thermal diffusivity. The findings values were compared with the results obtained in the tests of thermal performance, contributing to validation of the same. Ultimately, it was investigated the influence that changes in physical-chemical structure of the material had exerted on the variation of thermophysical quantities through gas pycnometry, scanning electron microscopy (SEM) combined with energy dispersive X-ray fluorescence spectroscopy (EDXRF), infrared spectroscopy using Fourier transform (FTIR), thermogravimetric analysis (TGA) and differential thermal analysis (DTA). Based on the results obtained was possible to demonstrate that all load percentage analyzed promoted an increase in the potential expansion (PE) of the resin. In production of the plates, the composites with density near at the free expansion presented high contraction during the cure, being the of higher density adopted as definitive standard. In the thermal performance tests, the heating and cooling curves of the different composites had presented symmetry and values very close for lines of the temperature. The results obtained for the thermophysical properties of composites, showed little difference in respect of pure foam. The percentage of open pores and irregularities in the morphology of the composites were proportionate to the increment of vermiculite. In the interaction between the matrix and dispersed phase, there were no chemical transformations in the region of interface and new compounds were not generated. The composites of PUR-NOP and vermiculite presented thermal insulating properties near the foam pure and percentage significantly less plastic in its composition, to the formulation with 10% of load

In the execution of civil engineering works, either by wasting during the coating of wall or demolition of gypsum walls, the generation of the gypsum waste involves serious environmental concerns. These concerns are increased by the high demand of this raw material in the sector and by the difficulties of proper disposal byproduct generated. In the search for alternatives to minimize this problem, many research works are being conducted, giving emphasis in using gypsum waste as fillers in composites materials in order to improve the acoustic, thermal and mechanical performances. Through empirical testing, it was observed that the crystallization water contained in the residue (CaSO4.2H2O) could act like primary agent in the expanding of the polyurethane foam. Considering that polyurethane produced from vegetable oils are biodegradable synthetic polymers and that are admittedly to represent an alternative to petrochemical synthetic polyurethane, this research consist an analysis of the thermal behavior of a composite whose matrix obtained from a resin derived from the expansive castor oil seed, with loads of 4%, 8%, 12% and 16% of gypsum waste replacing to the polyol prepolymer blend. Contributors to this analysis: a characterization of the raw material through analysis of spectroscopy by Fourier transform infrared (FTIR), chemical analysis by X-Ray Fluorescence (XRF) and mineralogical analysis by X Ray Diffraction (XRD), complemented by thermo gravimetric analysis (TGA). In order to evaluate the thermo physical properties and thermal behavior of the composites manufactured in die closed with expansion contained, were also carried tests to determine the percentage of open pore volume using a gas pycnometer, scanning electronic microscopy (SEM), in addition to testing of flammability and the resistance to contact with hot surfaces. Through the analysis of the results, it appears that it is possible to produce a new material, which few changes in their thermo physical properties and thermal performance, promotes significant changes and attractive to the environment
