4. Automated and observer based light field indicator edge evaluation in diagnostic X-ray equipment
Abstract Introduction To analyze edge detection and optical contrast calculation of light field-indicators used in X-ray via automated- and observer-based methods, and comparison with current standard approaches, which do not give exact definition for light field edge determination. Methods Automated light sensor array was used to measure the penumbra zone

5. MCM - 2 and Ki - 67 as proliferation markers in renal cell carcinoma: A quantitative and semi - quantitative analysis
ABSTRACT Introduction/Background: Fuhrman nuclear grade is the most important histological parameter to predict prognosis in a patient of renal cell carcinoma (RCC). However, it suffers from inter-observer and intra-observer variation giving rise to need of a parameter that not only correlates with nuclear grade but is also objective and reproducible. Proli

6. Ecology, behavior and natural history of the harvester ant Pogonomyrmex naegelii (Formicidae, Myrmicinae) in cerrado vegetation: activity schedule, diet, home range, nest structure and demography / Ecologia, comportamento e história natural da formiga ceifeira Pogonomyrmex naegelii (Formicidae, Myrmicinae) em cerrado : ritmo biológico, dieta, área de vida, estrutura e demografia dos ninhos
Pogonomyrmex naegelii belongs to the group known as harvester ants, which collects and stores seeds in underground chambers for later consumption. These ants can be found in both warm temperate and tropical regions around the world, especially in areas of semiarid to arid vegetation, although they may also be found in moist habitats. The following study prov

7. Propriedades de exchange bias e congelamento de spins de superfície em nanopartículas magnéticas
We present here magnetization measurements performed at low temperatures on magnetic nanocolloids based on 3.3 nm sized particles of manganese ferrite. This nanocolloid was obtained by a chemical core/shell strategy developed for the synthesis of ferro uids. Temperature dependence of the magnetization measurements allowed us to separate two contributions. On

8. Brazilian version of the foot health status questionnaire (FHSQ-BR): cross-cultural adaptation and evaluation of measurement properties
OBJECTIVE: To conduct a cross-cultural adaptation of the Foot Health Status Questionnaire into Brazilian-Portuguese and to assess its measurement properties. INTRODUCTION: This instrument is an outcome measure with 10 domains with scores ranging from 0-100, worst to best, respectively. The translated instrument will improve the examinations and foot care of

9. The face and the clothes: apprehending fashion billboards in urban environment / O rosto e a roupa: uma leitura dos outdoors de moda em ambientes urbanos
This inquiry studies urban communication and its devices of attention. The objects of this investigation are the fashion images printed in banners, billboards, images in buildings and interiors of shopping centers. The current metropolises show off the fact that they have being organized around the production and the seduction for almost two hundred years. I

10. Treinamento de redes neurais artificiais baseado em sistemas de estrutura variável com taxa de aprendizado adaptativa
This work presents new algorithms for training multilayer perceptron artificial neural networks based on stability properties of sliding mode variable structure systems. The main feature of the proposed algorithms is the adaptability of the gain (learning rate), which is obtained from each update step of the network weights, without the use of heuristics met

11. Inter-observer agreement in interpreting chest X-rays on children with acute lower respiratory tract infections and concurrent wheezing
CONTEXT AND OBJECTIVE: Many children with acute lower respiratory tract infections (ALRI) present to the emergency ward with concurrent wheezing. A chest x-ray is often requested to rule out pneumonia. We assessed inter-observer agreement in interpreting x-rays on such children. DESIGNS AND SETTING: Prospective consecutive case study at Instituto de Salud de

12. Wavelet transform in digital inpainting / Aplicação de wavelets em inpainting digital
Digital Inpainting is a recent techinique that allows the filling of missing information in images. One important attribute of a digital inpainting technique is the ability of altering an image in such a way that it is not simple for the human observer to detect the modification, characterizing an undetectable modification. The strategies for filling missing
