13. Efeito da ação tópica do colírio de fenilefrina a 10% no posicionamento palpebral de indivíduos normais e portadores de blefaroptose adquirida involucional / Effect of 10% phenylephrine eye drops action in the eyelid position in healthy subjects and in patients with acquired involutional blepharoptosis
INTRODUCTION: There are few studies in the literature on the effect of drugs on the vertical positioning of the eyelids. This issue is important in the analysis of the eyelid dynamics mainly in disorders such as blepharoptosis. The aim of this study is to determine the action of a single drop of 10% phenylephrine on the upper and lower eyelids of healthy sub

14. Processing and characterization of fully and partial nanostructured alumina powders and ceramics / Processamento e caracterização de pós e de cerâmicas de alumina total e parcialmente nanoestruturadas
The opportune access to trustworthy agricultural information has become very important for the decision process of national and international agents. The use of remote sensing to map agricultural crops must consider their high dynamism, therefore the use of methods that consider their spectral-temporal profile is needed. The Mato Grosso State Brazil became o

15. Metodo de posicionamento e dimensionamento 3D baseado em imagens digitais / 3D positioning and dimensioning method based on digital images
O trabalho apresenta um método baseado em imagens digitais para a determinação da posição espacial e do volume ocupado por um sólido. O objetivo é conhecer estes parâmetros sem a necessidade da reconstrução tridimensional completa do objeto. A aplicação da técnica proposta é baseada nas projeções da imagem do objeto a ser medido. O processo s

16. Sistema inteligente para detecção de manchas de óleo na superfície marinha através de imagens de SAR
Oil spill on the sea, accidental or not, generates enormous negative consequences for the affected area. The damages are ambient and economic, mainly with the proximity of these spots of preservation areas and/or coastal zones. The development of automatic techniques for identification of oil spots on the sea surface, captured through Radar images, ass

17. Identification of myofascial trigger points by computerized thermography / Termografia computadorizada na identificação de trigger points miofasciais
Computerized thermography, system with ability to capture the infrared light emissivity of any reflexive surface, is part of the current arsenal of instrumentation in biomechanics. Using this methodology, it is possible to evaluate the physiology of thermical maintenance through its skin surface representation. The aim of this work is to evaluate the thermog

18. Projeto de operadores de processamento e analise de imagens baseados na transformada imagem-floresta
t: In image processing and analysis, many problems can be thought of as an optimal image partition problem based on seed pixels, where each seed defines an influence zone composed by its "closest" pixels. The image foresting transform (1FT) is a unified and efficient approach to solve these problems, by reducing them into a shortest-path forest problem in

19. Sintese de efeitos fotograficos em computação de imagens
Photography, like other visual communication media, allows for manipulations that extend the repertoire of its expressive language, in order to surprise or mislead the viewer. These manipulations are often called "special effects". The production of synthetic images, using a computer, is a fairly recent visual communication medium subject to a sustained tech

20. Microspectroscopic imaging tracks the intracellular processing of a signal transduction protein: fluorescent-labeled protein kinase C beta I.
We have devised a microspectroscopic strategy for assessing the intracellular (re)distribution and the integrity of the primary structure of proteins involved in signal transduction. The purified proteins are fluorescent-labeled in vitro and reintroduced into the living cell. The localization and molecular state of fluorescent-labeled protein kinase C beta I

21. The Digital Anatomist Distributed Framework and Its Applications to Knowledge-based Medical Imaging
The domain of medical imaging is anatomy. Therefore, anatomic knowledge should be a rational basis for organizing and analyzing images. The goals of the Digital Anatomist Program at the University of Washington include the development of an anatomically based software framework for organizing, analyzing, visualizing and utilizing biomedical information.

22. Mapping of single-copy DNA sequences on human chromosomes by in situ hybridization with biotinylated probes: enhancement of detection sensitivity by intensified-fluorescence digital-imaging microscopy.
Two single-copy DNA segments of 6 kilobases (kb) and 2.3 kb were labeled with biotin-labeled dUTP (Bio11-dUTP) and hybridized to human chromosomes. These probes were detected by immunofluorescence and directly mapped on chromosomes by using classical fluorescence microscopy and a microchannel-plate-intensified video camera. By a subsequent R-banding, the 6-k

23. XML Schema Representation of DICOM Structured Reporting
Objective: The Digital Imaging and Communications in Medicine (DICOM) Structured Reporting (SR) standard improves the expressiveness, precision, and comparability of documentation about diagnostic images and waveforms. It supports the interchange of clinical reports in which critical features shown by images and waveforms can be denoted unambiguously by the

24. In vivo NMR microscopy allows short-term serial assessment of multiple skeletal implications of corticosteroid exposure
Corticosteroids are in widespread clinical use but are known to have adverse skeletal side effects. Moreover, it is not known how soon these effects become apparent. Here, we describe a longitudinal approach to evaluate the short-term implications of excess corticosteroid exposure by quantitative in vivo magnetic resonance imaging and spectroscopy in conjunc
