1. Human parvovirus B19 genotype 1 in suspected dengue patients of Tefé, Amazonas State, Brazil
Abstract INTRODUCTION: Human parvovirus B19 (B19V) is a common pathogen, which on infection causes variety of clinical conditions from benign self-limiting exanthematous disease and other similar pathologies to fetal death. METHODS: We collected 341 serum samples between the first and fourth day after the onset of symptoms from all patients suspected of de

2. Establishment of homogeneous zones in a soil of alluvial origin
RESUMO A capacidade do solo para manter o crescimento da planta e a actividade biológica reside nas suas propriedades físicas e químicas. O objectivo deste estudo foi observar a distribuição espacial das propriedades químicas do solo como pH, matéria orgânica (MO), condutividade eléctrica (CE), capacidade de troca catiônica eficaz (CTCE) e conteúd

3. O Professor e a Arte de Avaliar no Ensino Médico de uma Universidade no Brasil
RESUMO A avaliação é intrínseca ao ato de ensinar e uma possibilidade de ampliar e melhorar o conhecimento adquirido pelo aluno. No ensino na área da saúde, a avaliação possui peculiaridades e requer constante diálogo com os docentes e discentes a fim de receber aprimoramentos. O objetivo deste estudo foi traçar um diagnóstico inicial do processo

4. Influência de tratamento dentinário com EDTA sobre a resistência de união de sistemas adesivos autocondicionantes
Resumo Introdução Os adesivos autocondicionantes apresentam técnica adesiva simplificada e diminuição na sensibilidade pós-operatória. Quando aplicados sobre a dentina, atuam sobre a smear layer, cuja efetiva remoção ainda constitui um desafio. Uma substância utilizada como pré-tratamento dentinário na ajuda da remoção da smear layer é o eti

5. Floristic-functional variation of tree component along an altitudinal gradient in araucaria forest areas, in Southern Brazil
ABSTRACT We aimed to investigate the taxonomic and functional variations of tree component of Araucaria Forest (AF) areas located along an altitudinal gradient (700, 900 and 1,600 m asl), in the southern region of Brazil. The functional traits determined were leaf area, specific leaf area, wood density, maximum potential height and dispersal syndromes and de

6. Performance and Wake Analysis of Rotors in Axial Flight Using Computational Fluid Dynamics
ABSTRACT: Flow field around rotors in axial flight is known to be complex especially in steep descent where the rotor is operating inside its own wake. It is often reported that, in this flight condition, the rotor is susceptible to severe wake interactions causing unsteady blade load, severe vibration, loss of performance, as well as poor control and handli

7. Identificación Social y/o Percepción de Similitud: Aproximación a los Efectos Diferenciales sobre el Esencialismo
ABSTRACT The present study deals with the causal relation among two processes associated to essentialism (believing in the existence of a common essence for the members of a group): social identification and similarity. By means of a cross-correlational study, 200 participants (non-random sampling) were measured on both variables and on essentialism (ingroup

8. SELF-SIMILARITY OF VERTICAL BUBBLY JETS
AbstractAn integral model for vertical bubbly jets with nearly monodisperse bubble sizes is presented. The model is based on the Gaussian type self-similarity of mean liquid velocity, bubble velocity and void fraction, as well as on functional relationships for initial liquid jet velocity and radius, bubble diameter and relative velocity. Adjusting the model

9. Segmentação de pessoas em imagens estáticas baseada em esqueleto
The segmentation of people (automatic or semi-automatic) in still images is a very challenging task, mainly due to several factors in the real world, such as those related to the lighting of the scene where the image was captured, shadows, image noise, occlusions, high similarity of the object of interest with the background of the scene and the lack of info

10. Computational modelling of MHD unsteady flow and heat transfer toward a flat plate with Navier slip and Newtonian heating
The combined effects of Navier slip and Newtonian heating on an unsteady hydromagnetic boundary layer stagnation point flow towards a flat plate in the presence of a magnetic field are studied. The self-similar equations are obtained using similarity transformations and solved numerically by a shooting algorithm with a Runge-Kutta Fehlberg integration scheme

11. Fractal analysis of agricultural nozzles spray
Fractal scaling of the exponential type is used to establish the cumulative volume (V) distribution applied through agricultural spray nozzles in size x droplets, smaller than the characteristic size X. From exponent d, we deduced the fractal dimension (Df) which measures the degree of irregularity of the medium. This property is known as 'self-similarity'.

12. Crianças que se percebem competentes e são intrinsecamente motivadas são motoramente mais competentes? um estudo associativo entre desenvolvimento motor e aspectos psicossociais de escolares
This research aimed to investigate the perception of competence, motivational orientation and motor performance in children from public schools. More specifically we sought: check if children who have motor difficulties in gross motor skills fundamental also present difficulties in motor tasks specific to fine motor skills and balance, as well as the differe
