Modelo esportivo britânico: histórico e evoluções

The British sports suffered an unprecedented crisis in the early 80s instabilities political, economic crisis and lack of planning put the English sport in a very critical situation. However, a number of sports public policies were proposed from the 80's, effectively, completely changed the situation of English sport, which has prompted the development of this research. Thus, the present study, qualitative, aims to analyze the organization and evolution of the sport in the UK, based on the British government projects of the last 30 years included in the Sport Development database. Therefore, the study was developed by the union of bibliographic research, exploratory and documentary. First, after literature, documents were selected, using the academic database Sport Development, in the library of policy documents, separate area of the database containing only the English sport policy documents. For delimitation of the study were analyzed documents from 1980 to 2013, of which eight were selected on which to base discussions in this study. The documents were analyzed using thematic content analysis technique, based on two thematic axes: Axis 1 - funding and Axis 2 - priority groups. The results indicate that the analyzed initiatives show a process of evolution and maturation of public policies of Sport England, both on the issue of financing, such as with regard to priority groups, which have changed and adjustments over the years. It was also noted that much can be learned from these initiatives, even in helping to solve problems of the Brazilian reality. Suggest new studies involving sports management from different countries, in order to leverage other perspectives to support the development of public policies for sport and recreation in the country, seeking successful examples

Dinâmica secular rotacional de corpos tri-axiais: expansão de V em ressonâncias de primeira ordem

Consider a finite body of mass m (C1) with moments of inertia A, B and C. This body orbits another one of mass much larger M (C2), which at first will be taken as a point, even if it is not completely spherical. The body C1, when orbit C2, performs a translational motion near a Keplerian. It will not be a Keplerian due to external disturbances. We will use two axes systems: fixed in the center of mass of C1 and other inertial. The C1 attitude, that is, the dynamic rotation of this body is know if we know how to situate mobile system according to inertial axes system. The strong influence exerted by C2 on C1, which is a flattened body, generates torques on C1, what affects its dynamics of rotation. We will obtain the mathematical formulation of this problem assuming C1 as a planet and C2 as the sun. Also applies to case of satellite and planet. In the case of Mercury-Sun system, the disturbing potential that governs rotation dynamics, for theoretical studies, necessarily have to be developed by powers of the eccentricity. As is known, such expansions are delicate because of the convergence issue. Thus, we intend to make a development until the third order (superior orders are not always achievable because of the volume of terms generated in cases of first-order resonances). By defining a modern set of canonical variables (Andoyer), we will assemble a disturbed Hamiltonian problem. The Andoyer's Variables allow to define averages, which enable us to discard short-term effects. Our results for the resonant angle variation of Mercury are in full agreement with those obtained by D'Hoedt & Lemaître (2004) and Rambaux & Bois (2004)

Avaliação da biocompatibilidade de dois adesivos dentinários pelo estudo das reações teciduais em conjuntivo de ratos

The biocompatibility of two dentin adhesives (Scotchbond MultiPurpose- 3M and Optibond Multi-Use - Kerr) was evaluated in rats subcutaneous connective tissue implants. Polyethylene tubes filled with the adhesives were surgically implanted into the dorsal subcutaneous tissues of rats. The tubes were left implanted for periods of 14, 30, 60 and 84 days, following wich the animais were killed and the implants, together with the surrounding tissue, were excised. The specimens were then fixed in 10 per cent formalin, sectioned serially and stained with hematoxylin and eosin and then, examined by light microscopy. After 14 and 30 days the tubes were surrounded by a mild to moderate inflammatory infiltration. After 60 and 84 days microscopic examination revealed the formation of a connective tissue capsule around each tube. The microscopic examination of the biopsy specimens allowed to conclude that: a) both dentin adhesives are considered biologically acceptable when placed in contact with rats subcutaneous connective tissue; b) in the observation period of 30 days there were moderate tissue reaction to the Optibond Multi-Use -light cure- (Kerr); c) after 60 and 84 days the use of both dentine adhesives did not interfere in the healing of the surrounding connective tissue
