25. Expression and localization of myogenic regulatory factors (MyoD and Myogenin) in somatic rat muscle after reinervation with vein graft tubulization / Expressão e localização de fatores regulatórios miogênicos (MyoD e Miogenina) em músculos somíticos de ratos reinervados pela técnica de tubulização
Peripheral nerve injuries can result in the loss of propioception, morphological and functional alterations of muscle fibers which causes a negative impact on the quality of life. These injuries elicit an alteration on the expression of muscle specific genes, like MyoD and Myogenin, involved in the satellite cell activation and muscle mass regulation. The ve

26. Image quality in partially erased DenOptix® storage phosphor plates
This study aimed at investigating the effect of the partial erasing of DenOptix® system storage phosphor plates on the image quality of digital radiographs. Standardized digital radiographs were acquired of a phantom mandible, using size 2 intraoral DenOptix® storage phosphor plates (n = 10). Subsequently, the active areas of the plates were placed in a vi

28. Classification of beer by PCA and analysis of image / CLASSIFICAÇÃO DE CERVEJAS POR ANÁLISE DE IMAGENS E PCA
In this work a simple and new approach for lager beer pattern recognition based on image analysis was accomplished using Principal Component Analysis (PCA). Digital color images obtained from a scanner were decomposed into a binary form with the help of Scilab and SIP softwares. The PCA data matrix consisted of RGB color histograms for each sample. 350 mL be

31. Modelagem computacional de estruturas anatômicas em 3D e simulação de suas imagens radiográficas / Computational 3D modelling of anatomic structures and simulation of its radiography images
The conventional methods of quality control applied to radio diagnosis are the best way to have assured good quality of the produced images. Due the amount of variables to consider, the study of particular issues of the process of formation of radiological images requires complementary computational tools. However, the computational voxel based phantoms are

32. Processamento de amostras fecais e desenvolvimento da tecnica de analises de imagens por computador, para o diagnostico das enteroparasitoses / Processing of samples feces and development of the technique of analyses of images for computer, for the diagnosis of the enteroparasitoses
In the present study, we investigated on fecal sample processings, development and evaluation of a computer system for parasite image analysis. We observed that the fecal processing step was critical, but, essential for providing clean parasite structures, with reduced amount of fecal microdebris, to the system of computer analysis. Several conventional para
