2. Evaluation of bulk-fill systems: microtensile bond strength and non-destructive imaging of marginal adaptation
Abstract The objective of this study was to investigate microtensile bond strength (MTBS) and interfacial adaptation (IA) of bulk-fill restorative systems bonded to dentin in Class-I-preparations. Box-shaped preparations (4-mm-long, 3-mm-wide, 2-mm-high) made in extracted molars, and Teflon matrix with the same dimensions positioned over the occlusal surface

3. Implementação paralela do algoritmo iterativo de busca do parâmetro de regularização ótimo para o funcional de Tikhonov no problema de restauração de imagens / Parallel implementation of the iterative algorithm to search the optimal regularization parameter for the Tikhonov functional problem in image restoration
The use of techniques with the functional of Tikhonov in image processing has been widely used in recent years. The basic idea in this process is to modify an initial image using a convolution equation and to find a parameter which minimizes the function in order to obtain an aproximation of the original image. However, a typical problem in this method consi

4. Modelos variacionais em processamento de imagens - formulação primal e dual / Variational models in image processing - primal and dual formulation
Neste trabalho apresentamos alguns problemas de processamento de imagens cujas formulações são variacionais. Para exemplificar estas formulações consideramos o modelo proposto pelos autores Rudin, Osher e Fatemi (ROF) para o problema de remoção de ruídos. Para um melhor entendimento do problema alguns conceitos do Cálculo Variacional, em especial as

5. Retratamento endodôntico: casuística e comparação de dois métodos de diagnóstico por imagem / Endodontic retreatment: case studies and comparison of two methods of diagnosis by image
The radiographic test is an essential diagnosis component in the treatment of problems of endodontic origin. Despite the technical and scientific developments in endodontics, the number of endodontic retreatment continues high. In this scenario, Computerized Beam Cone Tomography (CBCT) is used to obtain three-dimensional images without distortions of structu

6. Células mononucleares autólogas de medula óssea na regeneração do nervo tibial em coelhos / Autologous mononuclear cells from bone marrow in the regeneration of tibial nerve in rabbits
The regeneration of peripheral nerves after injury has been target in researches for new technologies that lead to good results, so as to get completely restoration of nerve function. For such, many techniques have been developed using synthetic materials associated to exogenous factors that enhance the regeneration process, as mononuclear cells of bone marr

7. Effects of resin luting agents and 1% NaOCl on the marginal fit of indirect composite restorations in primary teeth
OBJECTIVE: The purpose of this study was to provide information regarding the marginal adaptation of composite resin onlays in primary teeth previously treated with 1% sodium hypochlorite (NaOCl) (pulp irrigant) using two different resin luting agents. MATERIAL AND METHODS: Forty extracted sound primary molars had their crowns prepared in a standardized mach

8. Mimetic finite difference methods in image processing
We introduce the use of mimetic methods to the imaging community, for the solution of the initial-value problems ubiquitous in the machine vision and image processing and analysis fields. PDE-based image processing and analysis techniques comprise a host of applications such as noise removal and restoration, deblurring and enhancement, segmentation, edge det

9. Geração e avaliação de produtos híbridos CBERS-2B para a identificação de fragmentos de vegetação arbórea / Generation and evaluation of CBERS-2B hybrid products for the identification of arboreal vegetation fragments
This study aims to evaluate two hybrid CBERS-2B products of 2.5 m and 10 m spatial resolution, for mapping forest fragments at Ibitinga Sao Paulo state, Brazil. In order to reduce the blurring effect in CBERS-2B images, the restoration methods Modified Inverse Filtering, Richardson-Lucy, Modified Richardson-Lucy and ones based on POCS theory and neural netwo

10. Combinação de modelos de campos aleatórios markovianos para classificação contextual de imagens multiespectrais / Combining markov random field models for multispectral image contextual classification
This work presents a novel MAP-MRF approach for multispectral image contextual classification by combining higher-order Markov Random Field models. The statistical modeling follows the Bayesian paradigm, with the definition of a multispectral Gaussian Markov Random Field model for the observations and a Potts MRF model to represent the a priori knowledge.

11. A IMAGEM DE DEUS NO SER HUMANO, SEGUNDO A TEOLOGIA DE EMIL BRUNNER: UM SER RELACIONAL E RESPONSÁVEL DIANTE DE DEUS / THE GODS IMAGE IN THE HUMAN BEING, ACCORDING TO EMIL BRUNNERS THEOLOGY: THE HUMAN BEING AS A RELATIONAL AND RESPONSIBLE IN THE FACE OF GOD
The human being is clearly a being that stands out from other types of life existing on earth. The Swiss theologian Emil Brunner understands this human dignity differential from the theological comprehension that the human being was created according to God`s Image. Even in the face of human evil, the human being is recognized by the Christian theology as so

12. Um estudo sobre a minimização de funcionais de expoente variável aplicados à restauração de imagens digitais / An study over the minimization of functionals of exponent variable applied to the restauration from digital images
Estuda-se neste trabalho um funcional com expoente variável, ou seja, com 1 ≤ p(x) ≤ 2, o qual fornece um modelo para a restauração de imagens digitais, mais precisamente para a remoção de ruídos. A difusão resultante do modelo proposto é uma combinação da Variação Total com a difusão isotrópica. A existência, unicidade e o comport
