Comparison of resting heart rate measured using a cardiac monitor and an oscilometric device in adolescents: Analysis of sensitivity and specificity
(2016-05-01)
Study design: Experimental study Objectives: To assess the consistency and efficiency of an oscillometric device for measuring resting heart rate in adolescents. Methods: Data from adolescents of both sexes aged between ...
Dielectric and non-ohmic analysis of Sr2+ influences on CaCu3Ti4O12-based ceramic composites
(2021-02-01)
In this study, CaCu3Ti4O12 ceramic composites were prepared through solid-state reaction by adding Sr2+ and removing Cu2+. Application of the Rietveld method and structure refinement revealed the presence of pure CaCu3Ti4O12 ...

Síntese e caracterização de óxidos termocrômicos para aplicação em dispositivos optoeletrônicos
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia de MateriaisUTFPR, 2015-11-16)
The thermochromism effect is present in various materials such as oxides of vanadium (V), tungsten and titanium, which have in a certain temperature a metal-insulator transition and thus change its properties with phase ...
A Smartphone-Based Low-Cost Inverted Laser Fluorescence Microscope for Disease Diagnosis
(MDPI, 2022)
Fluorescence microscopy is an important tool for disease diagnosis, often requiring costly optical components, such as fluorescence filter cubes and high-power light sources. Due to its high cost, conventional fluorescence ...
Silica coating on alumina ceramic: comparison of three chairside air-abrasion devices working for different times and distances.
(2011-03-01)
This study evaluated, by scanning electron microscope (SEM) and EDS, the effect of different strategies for silica coating (sandblasters, time and distance) of a glass-infiltrated ceramic (In-Ceram Alumina). Forty-one ...
