15. A modernidade do Cristo Redentor
Inspired by the proposal for a reading of modernity from Brazil, this paper focuses on three highlights in the history of the Christ the Redeemer statue on Corcovado Mountain in Rio de Janeiro. The first analyzes the meanings acquired by the idea of freedom of religion that allowed erecting a Catholic symbol in the national capital. The second reveals the co

16. Imagem in vitro do remanescente dentinÃrio e da cavidade pulpar atravÃs da tomografia por coerÃncia Ãptica
This work reports the application of optical coherence tomography (OCT) to generate image of remaining dentin and pulp chamber of in vitro human teeth. Bi-dimensional images of remaining dentin and of the pulp chamber were obtained parallel to the long axis of the teeth, by two OCT systems operating around 1280nm and 850nm, and compared with tomography image

17. A borboleta azul na parede de vidro: o imaginário medieval em Nove, novena, de Osman Lins
The core of approach of the writer Osman Linss lies in a restoration of the process of reconstructing the connection between the modern man to cosmos, applied to the called narratives abject, term of Walter Benjamin. That is because, when Middle Age allegory was rescued, Osman Lins constructs an interpretative way of this process that has as epicenter images

18. Estimativa da área e do tempo de permanência da vegetação secundária na amazônia legal por meio de imagens LANDSAT/TM
- Secondary vegetation, formed by natural regeneration of areas that are deforested and later abandoned, have many functions relevant to the ecology of the landscape in which it is embedded such as fixation of atmospheric carbon, maintenance of the biodiversity and the connection among forest remnants and restoration of soil fertility. The latter function is

19. Salvage reconstructive surgery in an adult patient with failed previous repair of an extrophy-epispadias complex: an operation with a functional and aesthetic purpose
Salvage surgical procedures after failed reconstruction for an extrophy-epispadias complex are extremely challenging. The goals are to restore continence and improve aesthetic appearance in order to provide quality of life and an improved body image to the patient. We describe the surgical steps in an adult patient who presented anal urinary incontinence and

20. Internal adaptation of cast titanium crowns
As the adaptation of titanium crowns obtained by Rematitan Plus investment, specific for titanium, is not recognized to be suitable, this study evaluated the effect of the concentration of the specific liquid and the temperature of the mold of investments on the internal misfit of crowns cast on commercially pure titanium. Individual dies of epoxy resin were

21. Wavelet transform in digital inpainting / Aplicação de wavelets em inpainting digital
Digital Inpainting is a recent techinique that allows the filling of missing information in images. One important attribute of a digital inpainting technique is the ability of altering an image in such a way that it is not simple for the human observer to detect the modification, characterizing an undetectable modification. The strategies for filling missing

22. Gap formation in composite restorations : evaluation techniques, effect of photoactivation methods and relantionship with bond strength / Formação de fendas em restaurações de composito : tecnicas de avaliação, efeito de metodos de fotoavaliação e relação com a resistencia da união
Gap formation in composite restorations has been characterized in this dissertation by way of evaluation techniques, modifying factors and the relationship between bond strength of the restorations and the dental structure. In Chapter 1 the objective was to compare the dye staining technique to Scanning Electron Microscopy (SEM) evaluation of gap formation i

23. Mapeamento de vegetação do estado de Minas Gerais utilizando dados MODIS / Vegetation mapping of Minas Gerais state using MODIS data
The use of moderate spatial resolution and almost temporal daily resolution satellite images is a viable option to monitor natural or cultivated vegetation and its dynamics. The State of Minas Gerais in Brazil, due to it´s diverse biomes and fisionomies was selected as the study area for dissertation. The aims of the present work were: (a) to analyze the ve

24. Proposição e avaliação de indicadores de desempenho para algoritmos de restauração de imagens / Proposition and evaluation of different performance indicators for image processing algorithms
The restoration of images acquired with Atomic Force Microscopes (AFM) consists on a very intense research area in nanotechnology. During the acquisition process the AFM images are subjected to the constraints imposed by the experimental apparatus usually presenting poor signal to noise ratios as well as the effects of tip-sample interaction. In order to pro
