1. Intra- and interobserver reliability of a modified distraction test based on digital images to assess lower eyelid horizontal tension
RESUMO Objetivo: A frouxidão palpebral inferior é avaliada classicamente por meio de testes de “snap-back” e “distraction test”. O objetivo deste estudo foi avaliar a reprodutibilidade da técnica utilizada para quantificar indiretamente a tensão horizontal nas pálpebras inferiores através do processamento digital de imagens. Métodos: Este es

4. Métodos temporales para determinar deformaciones límite en chapas metálicas
ABSTRACT The forming limit diagram (FLD) –broadly used to characterize sheet-metal formability– is made by means of strain measurement over the surface of stretched samples and the subsequent determination of limit-strain values associated with the onset of necking. Currently, researchers can make strain measurements with digital image-correlation analys

5. Peri-implant assessment via cone beam computed tomography and digital periapical radiography: an ex vivo study
OBJECTIVES: This research evaluated detail registration in peri-implant bone using two different cone beam computer tomography systems and a digital periapical radiograph. METHODS: Three different image acquisition protocols were established for each cone beam computer tomography apparatus, and three clinical situations were simulated in an ex vivo fresh p

6. Analysis of mesiodistal angulations of preadjusted brackets
Manufacturers offer various prescriptions of preadjusted brackets for use in the “straight-wire” orthodontic technique. However, the need to incorporate bends in the rectangular wires during orthodontic finishing has led to concerns regarding the type of prescription chosen and the credibility of information provided by the manufacturer. The aim of this

7. Classification of polymers insulators hydrophobicity basead on digital image processing
Although the hydrophobicity is usually an arduous parameter to be determined in the field, it has been pointed out as a good option to monitor aging of polymeric outdoor insulators. Concerning this purpose, digital image processing of photos taken from wet insulators has been the main technique nowadays. However, important challenges on this technique still

8. Evaluation of the accuracy of different transfer impression techniques for multiple implants
The aim of this study was to evaluate the accuracy of three implant transfer impression techniques. Four groups (n = 5) were defined, according to the technique: TC - tapered copings without splint; SC - square copings without splint; SCS - square copings splinted with dental floss and acrylic resin, and CG (control group) - master model with four external h

9. Macrozoneamento do Estado do Rio Grande do Sul
Earth imaging technologies using orbital platforms have allowed new approaches in the analyses, compartmentalization, and territorial visualization. These cartographic informations have many applications in agricultural, urban and environmental monitoring. In the case of vast geographic regions, such as Brazil, one expects that the many products obtained fro

10. O grotesco em uma busca de efeitos de sentido de estranhamento
This study investigates the effects of meaning related to estrangement that can lead to images being considered grotesque. the project began by identifying authors who have dealt with the theme of the grotesque within different theoretical frameworks and at different times and went on to study the principles and concepts of discursive semiotics, with the obj

11. Influence of post-cure treatments on hardness and marginal adaptation of composite resin inlay restorations: an in vitro study
OBJECTIVES: The purpose of this study was to evaluate the Vickers hardness number (VHN) and the in vitro marginal adaptation of inlay restorations of three hybrid composite resins (Filtek Z250, Opallis and Esthet-X) subjected to two post-cure treatments. MATERIAL AND METHODS: For the microhardness test, three different groups were prepared in accordance with

12. Desenvolvimento de metodologias para determinação do bem-estar e massa corporal de frangos de corte por meio de análise digital de imagens / Development of methodologies for determination of broiler chicken welfare and body mass by means of digital image analysis
Advances have been made in the field of image processing as a technology for development of a consistent response in relation to new standards in animal welfare. One of the advantages of artificial vision systems in relation to those of human vision is the ability to make exact measurements, based on pixel count. This system also has no influence on animal b
