1. A Model of Social Distancing for Interacting Age-Distributed Multi-Populations: An Analysis of Students’ In-Person Return to Schools
ABSTRACT Because of the current scenario of the SARS-CoV-2 (COVID-19) pandemic in Brazil, whose vaccination campaign is in its initial stage, government authorities have pointed towards the complete reopening of the economy. And recently, for the in-personal return of classroom teaching in schools. Given the family relationship, one of the questions that rem

2. Sanitary measures to contain COVID-19 spread decreased pediatric hospitalizations due to other respiratory infections in São Paulo, Brazil
Abstract Objective After the Covid-19 pandemics hit Brazil and sanitary measures were adopted to contain its dissemination, pediatric hospital admissions were apparently fewer than usual. The authors aimed to describe the time trends of public hospital admissions of children and adolescents due to respiratory infections (RIs) in São Paulo State, Brazil, be

3. Predictive model for difficult laryngoscopy using machine learning: retrospective cohort study
Abstract Background Both predictions and predictors of difficult laryngoscopy are controversial. Machine learning is an excellent alternative method for predicting difficult laryngoscopy. This study aimed to develop and validate practical predictive models for difficult laryngoscopy through machine learning. Methods Variables for the prediction of difficul

4. ADDITION OF NATURAL EXTRACTS WITH ANTIOXIDANT PROPERTIES IN BIODIESEL: ANALYSIS BY NEURAL NETWORKS OF THE MULTILAYER PERCEPTRON TYPE
Biodiesel is capable of replacing diesel because it has similar physicochemical properties, but this biofuel is susceptible to oxidation, which makes the application of antioxidant substances necessary. For this study, alcoholic extracts of senna leaves, hibiscus flowers, and blackberry were used. Biodiesel samples were submitted to physicochemical analysis

6. Estimation of body fat in children with intellectual disability: development and cross-validation of a simple anthropometric method
Abstract Objective Population-level monitoring of body composition requires accurate, biologically-relevant, yet feasible methods for estimating percent body fat (%BF). The aim of this study was to develop and cross-validate an equation for %BF from Body Mass Index (BMI), age, and sex among children with intellectual disability (ID). This study further aime

7. Simulation of Current Pulses and Sound Waves Resulting from Partial Discharges in a Needle-Plane Geometry in Air
Abstract Partial discharges can occur in different types of electric equipment and cause progressive insulation deterioration, so there is interest in monitoring partial discharges for assessing the state of the isolation of an electric system and to predict failures. Techniques to detect partial discharges, such as detecting ultrasonic emission, have been p

8. Numerical analysis of soft soil improved with stone column technique
Abstract The present research aims to do a numerical study on the behavior of a test embankment reinforced with stone column spacing of 1.85 m in a square grid with an average diameter of 1.0 m and 11.35 m length. The case study investigated the work in a steel company (ThyssenKrupp), located in Santa Cruz, western region of Rio de Janeiro - Brazil, where a

9. PHYTOREMEDIATION OF FLUORIDE-CONTAMINATED WATER BY Landoltia punctata
ABSTRACT Fluorine is released into the water environment naturally or by anthropogenic activities. Fluorine promotes health benefits at low concentrations, but it promotes adverse effects ranging from fluorosis to carcinogenic problems at high concentrations. Although fluorine removal from environment can occur through processes such as adsorption, reverse o

10. Direct healthcare costs and their relationships with age at start of drug use and current pattern of use: a cross-sectional study
ABSTRACT BACKGROUND: It is well known that early start of drug use can lead users to psychosocial problems in adulthood, but its relationship with users’ direct healthcare costs has not been well established OBJECTIVES: To estimate the direct healthcare costs of drug dependency treated at a community mental health service, and to ascertain whether earl

11. BDNF Val66Met polymorphism and resilience in major depressive disorder: the impact of cognitive psychotherapy
Objective: Clinical and biological correlates of resilience in major depressive disorder are scarce. We aimed to investigate the effect of the Val66Met polymorphism in the BDNF gene on resilience scores in major depressive disorder patients and evaluate the polymorphism’s moderation effect on resilience scores in response to cognitive therapy. Method: A

12. INSIGHT INTO THE CONFORMATIONAL SPACE OF N-BENZYL-N-(FURAN-2-YLMETHYL)ACETAMIDE BY NMR SPECTROSCOPY AND DFT CALCULATIONS
In this study, the conformational behavior of N-benzyl-N-(furan-2-ylmethyl) acetamide in chloroform was addressed by using a combined experimental/theoretical strategy using NMR spectroscopy and quantum chemical calculations. The 1H and 13C one-dimensional NMR spectra, as well as the two-dimensional HSQC-DEPT and HMBC-DEPT NMR spectra, evinced the presence o
