1. Effects of manual chest compression on expiratory flow bias during the positive end-expiratory pressure-zero end-expiratory pressure maneuver in patients on mechanical ventilation
RESUMO Objetivo: Avaliar os efeitos da compressão torácica manual (CTM) sobre o flow bias expiratório durante a manobra positive end-expiratory pressure-zero end-expiratory pressure (PEEP-ZEEP) para a remoção de secreção em pacientes sob ventilação mecânica invasiva. O flow bias, que influencia na remoção de secreção pulmonar, foi avaliado pel

2. Preparação de membranas de acetato de celulose organomodificadas para adsorção dos íons Cu(II), Cd(II), Mn(II) e Ni(II)
Cellulose acetate polymeric membranes had been prepared by a procedure of two steps, combining the method of phase inversion and the technique of hydrolysis-deposition. The first step was the preparation of the membrane, and together was organomodified with tetraethylortosilicate and 3-aminopropyltrietoxysilane. Parameters that exert influence in the complex

3. Airway clearance techniques in patients submitted to mechanical ventilation: A hemodynamic, gas exchange, respiratory mechanics and bronquial sputum study / Estudo do comportamento hemodinâmico, da troca gasosa, da mecânica respiratória e da análise do muco brônquico na aplicação de técnicas de remoção de secreção brônquica em pacientes sob ventilação mecânica
INTRODUCTION: Tracheal suction (TS) is a routine procedure in patients submitted to mechanical ventilation. In association, the bag-squeezing (BS) technique is described as a manual hyperinflation associated to a manually assisted coughing followed by TS. This technique might present few limitations as its mechanical ventilator disconnection and poor control

4. EXPERIMENTAL VALIDATION OF MODELS FOR PREDICTING THE FORCES FOR REMOVING WAX DEPOSITS IN PIPELINES USING PIGS / AVALIAÇÃO DE MODELOS PARA A REMOÇÃO DE DEPÓSITOS DE PARAFINA EM DUTOS UTILIZANDO PIGS
Pigging is still the most widely used method to remove wax deposits in subsea pipelines. The passage of a pig is still considered a risky operation, since the pressure gradient available for driving the pig might not be sufficient to overcome the contact forces between the pig and the wall, as well as the forces required to remove the wax deposit. If this is

5. Modelagem de vigas de compósitos laminados usando elementos finitos formulados na notação strain gradient
This work analyzes laminated .composite beams using finite elements formulated in strain gradient notation, which is a physically interpretable notation. Strain Gradient notation allows for the evaluation of modeling capabilities of finite elements, as well as for the identification and elimination of modeling errors a-priori. Initially a literature review i

6. Intron self-complementarity enforces exon inclusion in a yeast pre-mRNA
Skipping of internal exons during removal of introns from pre-mRNA must be avoided for proper expression of most eukaryotic genes. Despite significant understanding of the mechanics of intron removal, mechanisms that ensure inclusion of internal exons in multi-intron pre-mRNAs remain mysterious. Using a natural two-intron yeast gene, we have identified disti

7. Effect of sympathetic nerves on composition and distensibility of cerebral arterioles in rats.
1. The goals of this study were to examine the effects of chronic sympathetic denervation on the mechanics and composition of cerebral arterioles in normotensive Wistar Kyoto rats (WKY) and stroke-prone spontaneously hypertensive rats (SHRSP). 2. We used an in vivo method to examine the mechanics of pial arterioles in 10- to 12-month-old, anaesthetized WKY a

8. Mechanics of microtubule bundles in pillar cells from the inner ear.
The mechanical properties of cross-linked microtubule bundles were measured from outer pillar cells isolated from the mammalian inner ear. Measurements were made using a three-point bending test and were incorporated into a mathematical model designed to distinguish between the stiffness contributions from microtubules and their cross-linking proteins. Outer

9. Phosphorylation-dependent power output of transgenic flies: an integrated study.
We examine how the structure and function of indirect flight muscle (IFM) and the entire flight system of Drosophila melanogaster are affected by phosphorylation of the myosin regulatory light chain (MLC2). This integrated study uses site-directed mutagenesis to examine the relationship between removal of the myosin light chain kinase (MLCK) phosphorylation
