The aim of this study was to determine the clinical features and incidence of parapneumonic effusions throughout an 11-year period. MATERIAL AND METHODS We retrospectively reviewed the medical records of(More)
In this paper a method for the automatic DNA spots classification and extraction of profiles associated in DNA polyacrylamide gel electrophoresis is presented and it integrates the use of image processing techniques and chemometrics tools. A software which implements this method was developed; for feature extraction a combination of a PCA analysis and a(More)
A comparative study of four enhancement algorithms traditionally used in computer vision for photometric normalization of images affected by illumination changes is presented in this paper. We experimented with the performance of these approaches to reduce the low frequency multiplicative noise that is produced as a result of a non-homogeneity illumination(More)
Vascular anastomoses, carried out in a growing vessel, have certain peculiarities, since with the development of the artery a stenosis may remain in the suture zone which can compromise its success. We believe that the suture material should be absorbable. We carried out an experimental study in which we performed 18 anastomoses of the femoral artery in(More)
