Convulsões afebris benignas associadas a gastroenterite aguda ligeira

RESUMO Introdução: As convulsões afebris benignas associadas a gastroenterite aguda ligeira são crises convulsivas que ocorrem em apirexia, acompanhando quadros de gastroenterite aguda, sem desidratação ou distúrbios hidroeletrolíticos. Caso clínico: Descreve-se o caso de uma criança de 15 meses de idade com três episódios convulsivos associados a gastroenterite aguda ligeira. Clinicamente não apresentava febre...

Geodesic regression on spheres : a numerical optimization approach

In this paper we address the problem of finding a geodesic curve that best fits a given set of time-labeled points on a sphere. Since the corresponding normal equations are highly non-linear, we formulate the problem as a constrained nonlinear optimization problem and solve it using the routine fmincon from MATLAB with the SQP (Sequential Quadratic Programming) algorithm.

Integration of biosignal monitoring in sports clothing

The present paper gives an overview of the developments achieved in biosignal and sports performance monitoring in the context of the Bioswim project. The Bioswim project aims at developing technologies for integration of conventional as well as embedding novel textile sensors for the measurement, recording and transmission of biometric and performance parameters for athlete monitoring. The study object has be...

Infecção pelo vírus Epstein Barr e hepatite

Introdução: A infecção pelo vírus Epstein Barr (VEB) tem uma prevalência elevada sendo mais de 90% da população mundial seropositiva. A maioria das infecções primárias pelo VEB é subclínica. As complicações agudas são raras mas potencialmente letais. Caso clínico: Criança do sexo feminino com nove anos admitida por febre elevada com 13 dias de evolução, dor abdominal e odinofagia. Os exames auxiliares de diagnó...

Three-dimensional CFD analysis of the hand and forearm in swimming

The purpose of this study was to analyze the hydrodynamic characteristics of a realistic model of an elite swimmer hand/forearm using three-dimensional computational fluid dynamics techniques. A three-dimensional domain was designed to simulate the fluid flow around a swimmer hand and forearm model in different orientations (0°, 45°, and 90° for the three axes Ox, Oy and Oz). The hand/forearm model was obtained...

Moderate electric fields can inactivate Escherichia coli at room temperature

The inactivation of Escherichia coli using moderate electric fields (MEF) below 25 °C, was investigated. Keeping the temperature always below 25 °C demonstrated that electric fields are involved in the inactivation of E. coli, without possible synergistic temperature effects. Electric fields above 220 V cm−1 promoted death rates of 3 log10 cycles of E. coli in less than 6 min, and even higher rates at greater e...
