1. Light-Assisted Batch Injection Analysis of Glucose Exploiting a p-n-Homojunction Based on Cu2O
This work describes the development of a photoelectrochemical sensor for glucose quantification exploiting a light assisted-batch injection analysis (BIA) cell. A light-emitting diode (LED) lamp was employed to control the incidence of light on the p-Cu2O/n-Cu2O/fluorine-doped tin oxide (FTO) photoactive platform in BIA cell. The p-Cu2O/n-Cu2O/FTO platform w

2. Caracterização de termistores automotivos do tipo NTC
RESUMO Os termistores automotivos são eletrocerâmicas com características sensoras alojadas em estojos metálicos fixadas no radiador, que têm como função controlar a temperatura da água de resfriamento do motor. O objetivo deste trabalho foi caracterizar dois termistores comerciais aplicados em veículos automotores. Os termistores caracterizados for

4. Use of remote control in the intraoperative telemetry of cochlear implant: multicentric study
Resumo Introdução: A avaliação convencional da telemetria neural e de impedâncias implica o uso do computador acoplado a uma interface, o software fornece o estímulo e a visualização das respostas. Recentemente, foi lançado um controle remoto (CR220®), que possibilita testes intraoperatórios com instrumental mínimo. Objetivo: Avaliar a concord�

5. Microbiologically-Influenced Corrosion of 1020 Carbon Steel in Artificial Seawater Using Garlic Oil as Natural Biocide
This work aims evaluate the use of biocides in the microbiologically-influenced corrosion (MIC) of AISI 1020 carbon steel by sulfate-reducing bacteria (SRB) in artificial seawater. A natural biocide (garlic oil) and a commercial biocide (glutaraldehyde) were used to control the corrosion caused by these bacteria in artificial seawater. Microbial growth on th

6. Impedance Cardiography in the Evaluation of Patients with Arterial Hypertension
Abstract Arterial hypertension is responsible for high morbidity and mortality. Despite increasing awareness of the consequences of uncontrolled hypertension and the publication of several recommendations and guidelines, blood pressure control rates are suboptimal, and approximately half of the patients do not reach the targets. Defined as an increase in blo

8. Electrochemical corrosion characterization of nickel aluminides in acid rain
ABSTRACT Nickel aluminides have been extensively studied in recent decades to replace superalloys, in some components of aircraft turbines, because they have excellent corrosion resistance. Many industrial cities have the problem of air pollution, which has forced the study of the degradation of these alloys in the presence of acid rain. The aim of this work

9. Variation in the Hearing Threshold in Women during the Menstrual Cycle
Abstract Introduction The hormonal changes that occur during the menstrual cycle and their relationship with hearing problems have been studied. However, they have not been well explained. Objective The objective of our study is to investigate the variation in hearing thresholds in women during the menstrual cycle. Method We conducted a cohort and long

10. Changes in weight and body fat after use of tetracycline and Lactobacillus gasseri in rats
ABSTRACT Recent studies have shown a role of intestinal microbiota in obesity. The consumption of antibiotics in the last 70 years has led to changes in intestinal microbiota, which has led to weight gain and body fat accumulation. To evaluate the possibility of weight gain induced by antibiotics and the possible protective effect of probiotics, we divided 4

11. Substrate Integrated Waveguide (SIW) Bandpass Filter with Novel Microstrip-CPW-SIW Input Coupling
Abstract A Substrate integrated waveguide bandpass filter is presented with a novel CPW-to-SIW transition at both the input and output ports which also served as the input and output couplings into the filter. The CPW-to-SIW transition structures presented here exploited the step impedance between the 50 ohms input/output feedline and the transition to contr

12. Experimental Validation of a Cardiac Simulator for in vitro Evaluation of Prosthetic Heart Valves
Abstract Objective: This work describes the experimental validation of a cardiac simulator for three heart rates (60, 80 and 100 beats per minute), under physiological conditions, as a suitable environment for prosthetic heart valves testing in the mitral or aortic position. Methods: In the experiment, an aortic bileaflet mechanical valve and a mitral biop
