Em 1870, o jovem e praticamente desconhecido Benjamin Franklin Ramiz Galvão foi nomeado para ocupar o cargo de diretor da Biblioteca Nacional, posto do qual saiu doze anos depois, já como intelectual consagrado, para assumir a função de tutor dos netos de D. Pedro II. Durante o período em que esteve à frente desta instituição, Ramiz Galvão projetou fazer daquele espaço a biblioteca da nação brasileira. Isso significava construir uma instituição cuja função fosse salvaguardar o patrimônio documental brasileiro, torná-lo disponível a um público especializado e estimular estudos sobre a história e a geografia do país. O objetivo era fazer da Biblioteca Nacional um lugar de referência, sintonizada com suas congêneres europeias e em diálogo com os meios letrados nacionais. Nesse sentido, a atuação de Galvão foi fundamental para a construção de uma rede de sociabilidade que o ligava a estudiosos, livreiros, bibliófilos e bibliotecários de diversos lugares do Brasil, da América e da Europa. Esta tese analisa a proposta de reformulação da Biblioteca Nacional empreendida por Ramiz Galvão, buscando associá-la a um projeto maior de construção da nação brasileira. Para isso, investigaremos três elementos que consideramos principais desse trabalho de edificação de uma Biblioteca nacional: 1) a construção de uma rotina de serviços, que foi capaz de transformar o pequeno espaço com livros da antiga Biblioteca Real na mais importante biblioteca do Brasil; 2) o esforço de aquisição e de seleção de um patrimônio documental brasileiro e sua divulgação em publicações como os Anais da Biblioteca Nacional e o Catálogo da Exposição de História do Brasil, dois de seus mais importantes empreendimentos como diretor; 3) a atuação de Ramiz Galvão como mediador cultural no ambiente letrado brasileiro do final do século XIX.

The 1988 Federal Constitution of Brazil by presenting the catalog of fundamental rights and guarantees (Title II) provides expressly that such rights reach the social, economic and cultural rights (art. 6 of CF/88) as a means not only to ratify the civil and political rights, but also to make them effective and practical in the life of the Brazilian people, particularly in the prediction of immediate application of those rights and guarantees. In this sense, health goes through condition of universal right and duty of the State, which should be guaranteed by social and economic policies aimed at reducing the risk of disease and other hazards, in addition to ensuring universal and equal access to actions and services for its promotion, protection and recovery (Article 196 by CF/88). Achieving the purposes aimed by the constituent to the area of health is the great challenge that requires the Health System and its managers. To this end, several policies have been structured in an attempt to establish actions and services for the promotion, protection and rehabilitation of diseases and disorders to health. In the mid-90s, in order to meet the guidelines and principles established by the SUS, it was established the Política Nacional de Atenção Oncológica PNAO, in an attempt to sketch out a public policy that sought to achieve maximum efficiency and to be able to give answers integral to effective care for patients with cancer, with emphasis on prevention, early detection, diagnosis, treatment, rehabilitation and palliative care. However, many lawsuits have been proposed with applications for anticancer drugs. These actions have become very complex, both in the procedural aspects and in all material ones, especially due to the highcost drugs more requested these demands, as well as need to be buoyed by the scientific evidence of these drugs in relation to proposed treatments. The jurisprudence in this area, although the orientations as outlined by the Parliament of Supreme Court is still in the process of construction, this study is thus placed in the perspective of contributing to the effective and efficient adjudication in these actions, with focus on achieving the fundamental social rights. Given this scenario and using research explanatory literature and documents were examined 108 lawsuits pending in the Federal Court in Rio Grande do Norte, trying to identify the organs of the Judiciary behave in the face of lawsuits that seeking oncology drugs (or antineoplastic), seeking to reconcile the principles and constitutional laws and infra constitutional involving the theme in an attempt to contribute to a rationalization of this judicial practice. Finally, considering the Rational Use of health demands and the idea of belonging to the Brazilian people SUS, it is concluded that the judicial power requires ballast parameters of their decisions on evidence-based medicine, aligning these decisions housing constitutional principles that the right to health and the scientific conclusions of efficacy, effectiveness and efficiency in oncology drugs, when compared to the treatments offered by SUS

The right to housing is included in several international human rights instruments and in Brazilian legal system integrates the constitutional catalog of fundamental social rights (art. 6) and urban development policy (art. 182 and 183). Besides, it is for all federative governments its effectiveness by building programs and improvement of housing conditions and sanitation (art. 23, IX), which justifies the investment in urban planning and public policy of housing affordability because they are tools for achieving this right. Newer strategies in this area have been based on tax incentives, combined with the mortgage as a way to induce the construction of new housing units or reform those in a precarious situation. However, there is still a deficit households and environmental soundness, compounded with the formation of informal settlements. Consequently, we need constant reflections on the issue, in order to identify parameters that actually guide their housing policies in order to meet the constitutional social functions of the city and ensure well-begins of its citizens (art. 182). On the other hand, the intervention of the government in this segment can not only see the availability of the home itself, but also the quality of your extension or surroundings, observing aspects related to environmental sanitation, urban mobility, leisure and services essential health, education and social assistance. It appears that the smoothness and efficiency of a housing policy condition to the concept of adequate housing, in other words, structurally safe, comfortable and environmentally legally legitimate, viable from the extensive coordination with other public policies. Only to compliance with this guideline, it is possible to realize the right to housing in sustainable cities

Pythagoras was one of the most important pre-Socratic thinkers, and the movement he founded, Pythagoreanism, influenced a whole thought later in religion and science. Iamblichus, an important Neoplatonic and Neopythagorean philosopher of the third century AD, produced one of the most important biographies of Pythagoras in his work Life of Pythagoras. In it he portrays the life of Pythagoras and provides information on Pythagoreanism, such as the Pythagorean religious community which resembled the cult of mysteries; the Pythagorean involvement in political affairs and in the government in southern Italy, the use of music by the Pythagoreans (means of purification of healing, use of theoretical study), the Pythagorean ethic (Pythagorean friendship and loyalty, temperance, self-control, inner balance); justice; and the attack on the Pythagoreans. Also in this biography, Iamblichus, almost seven hundred years after the termination of the Pythagorean School, established a catalog list with the names of two hundred and eighteen men and sixteen women, supposedly Pythagoreans of different nationalities. Based on this biography, a question was raised: to what extent and in what ways, can the Pythagoreans quoted by Iamblichus really be classified as Pythagoreans? We will take as guiding elements to search for answers to our central problem the following general objectives: to identify, whenever possible, which of the men and women listed in the Iamblichus catalog may be deemed Pythagorean and specific; (a) to describe the mystery religions; (b) to reflect on the similarities between the cult of mysteries and the Pythagorean School; (c) to develop criteria to define what is being a Pythagorean; (d) to define a Pythagorean; (e) to identify, if possible, through names, places of birth, life, thoughts, work, lifestyle, generation, etc.., each of the men and women listed by Iamblichus; (f) to highlight who, in the catalog, could really be considered Pythagorean, or adjusting to one or more criteria established in c, or also to the provisions of item d. To realize these goals, we conducted a literature review based on ancient sources that discuss the Pythagoreanism, especially Iamblichus (1986), Plato (2000), Aristotle (2009), as well as modern scholars of the Pythagorean movement, Cameron (1938), Burnet (1955), Burkert (1972), Barnes (1997), Gorman (n.d.), Guthrie (1988), Khan (1999), Mattéi (2000), Kirk, Raven and Shofield (2005), Fossa and Gorman (n.d.) (2010). The results of our survey show that, despite little or no availability of information on the names of alleged Pythagoreans listed by Iamblichus, if we apply the criteria and the definition set by us of what comes to be a Pythagorean to some names for which we have evidence, it is possible to assume that Iamblichus produced a list which included some Pythagoreans

Among the many methodological resources that the mathematics teacher can use in the classroom, we can cite the History of Mathematics which has contributed to the development of activities that promotes students curiosity about mathematics and its history. In this regard, the present dissertation aims to translate and analyze, mathematically and historically, the three works of Euler about amicable numbers that were writed during the Eighteenth century with the same title: De numeris amicabilibus. These works, despite being written in 1747 when Euler lived in Berlin, were published in different times and places. The first, published in 1747 in Nova Acta Eruditorum and which received the number E100 in the Eneström index, summarizes the historical context of amicable numbers, mentions the formula 2nxy & 2nz used by his precursors and presents a table containing thirty pairs of amicable numbers. The second work, E152, was published in 1750 in Opuscula varii argument. It is the result of a comprehensive review of Euler s research on amicable numbers which resulted in a catalog containing 61 pairs, a quantity which had never been achieved by any mathematician before Euler. Finally, the third work, E798, which was published in 1849 at the Opera postuma, was probably the first among the three works, to be written by Euler

In the present work, we have studied the nature of the physical processes of the coronal heating, considering as basis significant samples of single and binary evolved stars, that have been achieved with the ROSAT satellite. In a total of 191 simple stars were studied, classified in the literature as giants with spectral type F, G and K. The results were compared with those obtained from 106 evolved stars of spectral type F, G and K, which belong to the spectroscopic binary systems. Accurate measurements on rotation and information about binarity were obtained from De Medeiros s catalog. We have analysed the behavior of the coronal activity in function of diverse stellar parameters. With the purpose to better clarify the profile of the stars evolution, the HR diagram was built for the two samples of stars, the single and the binary ones. The evolved traces added in the diagram were obtained from the Toulouse-Geneve code, Nascimento et al. (2000). The stars were segregated in this diagram not only in range of rotational speed but also in range of X-ray flux. Our analysis shows clearly that the single stars and the binary ones have coronal activity controlled by physical process independent on the rotation. Non magnetic processes seem to be strongly influencing the coronal heating. For the binary stars, we have also studied the behavior of the coronal emission as a function of orbital parameters, such as period and eccentricity, in which it was revealed the existence of a discontinuity in the emission of X-rays around an orbital period of 100 days. The study helped to conclude that circular orbits of the binary stars are presented as a necessary property for the existence of a higher level ofX-rays emission, suggesting that the effect of the gravitational tide has an important role in the coronal activity level. When applied the Kolmogorov-Smirnov test (KS test ) for the Vsini and FX parameters to the samples of single and binary stars, we could evidence very relevant aspects for the understanding of the mechanisms inherent to the coronal activity. For the Vsini parameter, the differences between the single stars and the binary ones for rotation over 6.3 km/s were really remarkable. We believe, therefore, that the existence of gravitational tide is, at least, one of the factors that most contribute for this behavior. About the X-rays flux, the KS test showed that the behavior of the single and the binary stars, regarding the coronal activity, comes from the same origin

The interest in the systematic analysis of astronomical time series data, as well as development in astronomical instrumentation and automation over the past two decades has given rise to several questions of how to analyze and synthesize the growing amount of data. These data have led to many discoveries in the areas of modern astronomy asteroseismology, exoplanets and stellar evolution. However, treatment methods and data analysis have failed to follow the development of the instruments themselves, although much effort has been done. In present thesis, we propose new methods of data analysis and two catalogs of the variable stars that allowed the study of rotational modulation and stellar variability. Were analyzed the photometric databases fromtwo distinctmissions: CoRoT (Convection Rotation and planetary Transits) and WFCAM (Wide Field Camera). Furthermore the present work describes several methods for the analysis of photometric data besides propose and refine selection techniques of data using indices of variability. Preliminary results show that variability indices have an efficiency greater than the indices most often used in the literature. An efficient selection of variable stars is essential to improve the efficiency of all subsequent steps. Fromthese analyses were obtained two catalogs; first, fromtheWFCAMdatabase we achieve a catalog with 319 variable stars observed in the photometric bands Y ZJHK. These stars show periods ranging between ∼ 0, 2 to ∼ 560 days whose the variability signatures present RR-Lyrae, Cepheids , LPVs, cataclysmic variables, among many others. Second, from the CoRoT database we selected 4, 206 stars with typical signatures of rotationalmodulation, using a supervised process. These stars show periods ranging between ∼ 0, 33 to ∼ 92 days, amplitude variability between ∼ 0, 001 to ∼ 0, 5 mag, color index (J - H) between ∼ 0, 0 to ∼ 1, 4 mag and spectral type CoRoT FGKM. The WFCAM variable stars catalog is being used to compose a database of light curves to be used as template in an automatic classifier for variable stars observed by the project VVV (Visible and Infrared Survey Telescope for Astronomy) moreover it are a fundamental start point to study different scientific cases. For example, a set of 12 young stars who are in a star formation region and the study of RR Lyrae-whose properties are not well established in the infrared. Based on CoRoT results we were able to show, for the first time, the rotational modulation evolution for an wide homogeneous sample of field stars. The results are inagreement with those expected by the stellar evolution theory. Furthermore, we identified 4 solar-type stars ( with color indices, spectral type, luminosity class and rotation period close to the Sun) besides 400 M-giant stars that we have a special interest to forthcoming studies. From the solar-type stars we can describe the future and past of the Sun while properties of M-stars are not well known. Our results allow concluded that there is a high dependence of the color-period diagram with the reddening in which increase the uncertainties of the age-period realized by previous works using CoRoT data. This thesis provides a large data-set for different scientific works, such as; magnetic activity, cataclysmic variables, brown dwarfs, RR-Lyrae, solar analogous, giant stars, among others. For instance, these data will allow us to study the relationship of magnetic activitywith stellar evolution. Besides these aspects, this thesis presents an improved classification for a significant number of stars in the CoRoT database and introduces a new set of tools that can be used to improve the entire process of the photometric databases analysis

The recent astronomical observations indicate that the universe has null spatial curvature, is accelerating and its matter-energy content is composed by circa 30% of matter (baryons + dark matter) and 70% of dark energy, a relativistic component with negative pressure. However, in order to built more realistic models it is necessary to consider the evolution of small density perturbations for explaining the richness of observed structures in the scale of galaxies and clusters of galaxies. The structure formation process was pioneering described by Press and Schechter (PS) in 1974, by means of the galaxy cluster mass function. The PS formalism establishes a Gaussian distribution for the primordial density perturbation field. Besides a serious normalization problem, such an approach does not explain the recent cluster X-ray data, and it is also in disagreement with the most up-to-date computational simulations. In this thesis, we discuss several applications of the nonextensive q-statistics (non-Gaussian), proposed in 1988 by C. Tsallis, with special emphasis in the cosmological process of the large structure formation. Initially, we investigate the statistics of the primordial fluctuation field of the density contrast, since the most recent data from the Wilkinson Microwave Anisotropy Probe (WMAP) indicates a deviation from gaussianity. We assume that such deviations may be described by the nonextensive statistics, because it reduces to the Gaussian distribution in the limit of the free parameter q = 1, thereby allowing a direct comparison with the standard theory. We study its application for a galaxy cluster catalog based on the ROSAT All-Sky Survey (hereafter HIFLUGCS). We conclude that the standard Gaussian model applied to HIFLUGCS does not agree with the most recent data independently obtained by WMAP. Using the nonextensive statistics, we obtain values much more aligned with WMAP results. We also demonstrate that the Burr distribution corrects the normalization problem. The cluster mass function formalism was also investigated in the presence of the dark energy. In this case, constraints over several cosmic parameters was also obtained. The nonextensive statistics was implemented yet in 2 distinct problems: (i) the plasma probe and (ii) in the Bremsstrahlung radiation description (the primary radiation from X-ray clusters); a problem of considerable interest in astrophysics. In another line of development, by using supernova data and the gas mass fraction from galaxy clusters, we discuss a redshift variation of the equation of state parameter, by considering two distinct expansions. An interesting aspect of this work is that the results do not need a prior in the mass parameter, as usually occurs in analyzes involving only supernovae data.Finally, we obtain a new estimate of the Hubble parameter, through a joint analysis involving the Sunyaev-Zeldovich effect (SZE), the X-ray data from galaxy clusters and the baryon acoustic oscillations. We show that the degeneracy of the observational data with respect to the mass parameter is broken when the signature of the baryon acoustic oscillations as given by the Sloan Digital Sky Survey (SDSS) catalog is considered. Our analysis, based on the SZE/X-ray data for a sample of 25 galaxy clusters with triaxial morphology, yields a Hubble parameter in good agreement with the independent studies, provided by the Hubble Space Telescope project and the recent estimates of the WMAP

This study investigated factors that influence the group size during the behavior foraging of estuarine dolphin Sotalia guianensis in the coast south of the state Rio Grande do Norte (RN), it also characterized the diet of estuarine dolphins and elaborated an otoliths catalog for aid in the identification of the preys found in the stomach contents. In relation to the group size during behaviour foraging, inside of the Curral Bay, larger frequency of solitary hunt was observed. Factors as tide variation, group composition and seasons didn't present correlation with the number of animals observed during a feeding episode. Capture success for participant was shown significantly larger when the animals hunted alone, what possibly explains the largest frequency of solitary hunt inside of the Curral Bay. About diet, were identified 18 bone fishes species, with predominance of species the families Haemulidae and Sciaenidae and five cephalopods species, including two new species in the diet of Sotalia guianensis in Brazil. Our results indicated that estuarine dolphin in the coast oriental from Rio Grande do Norte (RN) feeds predominantly of fish that form shoal, of habitat estuarino and producing of sounds. The analysis of the images, otoliths of 43 species of coastal fish of the coast of the state of Rio Grande do Norte (RN), aided by the offered descriptions, demonstrated to be an effective methodology for the knowledge of those structures, as well as it represented a form of reducing the subjectivity in the identification of the bone fishes found in stomach content

We present the results of a study on vinyl bromide for the search for new far infrared (FIR) laser lines. As the pump source, we use a CW waveguide CO2 laser with a tunability of 290 MHz around each line in order to pump large offset vibrational transitions. As a consequence, we obtained 28 new FIR laser emissions; 24 of them have wavelengths greater than 500 mum and are, therefore, suitable to be used in high-field EPR spectroscopy, For each of the new lines, we give the wavelength, the offset of the pumping transition with respect to the center Frequency of the CO2 emission, the polarization relative to that of the pumping laser line, the operating pressure, and the relative intensity. We also present a catalog including data of all of the FIR laser lines observed from this molecule up to now.

Na atualidade a atribuição dos descritores de assuntos ou indexação do conteúdo dos livros, nem sempre está associada ao contexto concreto de cada biblioteca, provocando, em muitos casos, que a recuperação por assuntos não resulte adequada. Neste trabalho analisam-se os principais desafios e perspectivas da indexação dos livros, os avanços de análises de assuntos nos catálogos de bibliotecas, examinam-se procedimentos, instrumentos, regras e condutas utilizadas nas análises e representação do conteúdo dos livros. Também se mostra a interação entre o ensino, a pesquisa e a atuação profissional necessária para que os estudantes possam desenvolver competências na análise, na representação e na procura da informação, assim como os princípios - provavelmente menos evidentes- da organização do conhecimento. Este trabalho coloca em evidência que as políticas de gestão da informação, mais quantitativas que qualitativas, deixam num segundo plano o processamento intelectual do conteúdo prejudicando, desta maneira, a recuperação por assuntos através do catalogo da biblioteca. Finalmente, se recolhe uma serie de propostas docentes relacionadas com a atribuição de descritores de assuntos em contextos bibliotecários.

The aim of this paper is to evaluate the consistency indexes among 30 Brazilian university libraries from the south and south-east regions through a specific mathematical formula. It was selected a sample of 30 university libraries that, according to the information in their official sites, have a collection consisted of more than 100.000 copies and allow the search into the on-line catalog. Searches were carried out in every university by means of their sites, requesting books that contained a certain word in its title and were printed in a certain year. The response was a list of available titles in the library, from which we chose at random a title and asked to visualize the complete record to verify the existence of a given subject. This procedure was repeated until we found the same title in five libraries with the chosen subjects. The result is 10 trials, each one consisting of one figure and one table showing the selected libraries, the subjects, the documentary languages ( tools) and the consistency indexes relaxed and rigid. These trials show great discrepancy between the values of consistency indexes with intervals between 73,3% to 34,4% in the relaxed index, and between 60% and 9,6% in the rigid one. It was revealed that the coincidence in determining the subjects is not too high remaining below 39%. It is concluded that the difference between the consistency indexes may be due to factors as: incompatibility among documentary languages; lack of updating of these languages so as to follow the knowledge evolution; absence of a well-defined indexing policy with guidelines clearly established. Procedures of indexing followed by indexers could contribute to the consistency index to be bigger in percentage, since there would be parameters for the indexing process.
