1. Percutaneous tracheostomy in COVID-19 patients: a new apneic approach
Abstract Background: Percutaneous dilation tracheostomy is an aerosol-generating procedure carrying a documented infectious risk during respiratory virus pandemics. For this reason, during the COVID-19 outbreak, surgical tracheostomy was preferred to the percutaneous one, despite the technique related complications increased risk. Methods: We describe a ne

4. Diagnostic reliability of an immunochromatographic test for Chagas disease screening at a primary health care centre in a rural endemic area
Many patients with Chagas disease live in remote communities that lack both equipment and trained personnel to perform a diagnosis by conventional serology (CS). Thus, reliable tests suitable for use under difficult conditions are required. In this study, we evaluated the ability of personnel with and without laboratory skills to perform immunochromatographi

5. Positive serology for viral hepatitis and donor self-exclusion in Southern Brazil
Introduction Despite the great advances in serological testing for transfusion-transmitted infections, the selection of blood donors by blood bank operators remains the only way to avoid transmission within the testing window period. Part of this selection is the self-exclusion form, on which the donors can exclude their blood from donation without any expl

6. Reliability and accuracy of a radiographic analysis method for posterior maxillary mini-implant location
OBJECTIVE: The purpose of this study was to evaluate the reliability and accuracy of a radiographic analysis method for the location of mini-implants inserted in the posterior region of the maxilla. MATERIAL AND METHODS: Two self-drilling mini-implants were installed between the second premolar and the first molar on the right side and left side in three dry

7. Decaimento dos autovalores de operadores integrais positivos gerados por núcleos Laplace-Beltrami diferenciáveis / Eigenvalue decay of positive integral operators generated by Laplace-Beltrami differentiable kernels
Neste trabalho obtemos taxas de decaimento para autovalores e valores singulares de operadores integrais gerados por núcleos de quadrado integrável sobre a esfera unitária em \ R POT. m+1\ , m 2, sob hipóteses sobre ambos, certas derivadas do núcleo e o operador integral gerado por tais derivadas. Este tipo de problema é comum na literatura, mas as hip

8. Positive integral operators and reproducing kernel Hilbert spaces / Operadores integrais positivos e espaços de Hilbert de reprodução
In this work we study theoretical properties of positive integral operators on L POT. 2(X; u), in the case when X is a topological space, either locally compact or first countable, and u is a strictly positive measure. The analysis is directed to spectral properties of the operator which are related to some extensions of Mercers Theorem and to the study of t

9. Identificação dos parâmetros necessários para análise de rede de estrutura múltipla com base na análise por simulação de fluxo TCP por vazão de fluidos
The major worldwide operators of transport in telecommunication networks have sought tools that, together with traffic statistics, allow their infrastructure to be enabled such that there is no rejection or delay of traffic due to transport capacity. Observing a private network with a considerable geographic size and, for a private high-density network with

10. Operadores integrais gerados por núcleos em multi-escalas / Integral operators generated by multi-scale kernels
We study Mercer like kernels, a very special class of positive definite kernels possessing the description given by many results labeled as Mercers Theorem. We explore some of their properties which are needed in the development of this work and construct their native space. In the second half of the work, we consider Mercer kernels defined by a multi-scale

11. A organizaÃÃo relacional de textos argumentativos escritos em inglÃs - lÃngua estrangeira com ou sem operadores / The relational organization of argumentative texts written in English - foreign language
The relational organization of argumentative texts written in English/foreign language is a study that has as purpose of analyzing the organization of the argumentative sequences concerning the presence and the absence of argumentative operators. For this, the research concentrates an inductive, objective, descriptive broaching about the place and the worth
