1. Bayesian modeling of the maximum streamflows from the Furnas reservoir
ABSTRACT The objective of this work was to predict the maximum flow of the Furnas reservoir in the dry and wet periods. The generalized distribution of extreme values (GEV) was used with parameter estimation via Bayesian inference. Data on average daily streamflows corresponding to the years 1965 to 2017 were obtained from Hidroweb, by the National Agency fo

2. 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

3. VAAFT PROCEDURE (Video-assisted Anal Fistula Treatment) versus Open Method in the Treatment of High Fistula in Ano
Abstract Background A common acquired anorectal condition is anal fistula. The treatment approaches that have been employed have been linked to erratic outcomes and sometimes life-threatening consequences. Video-assisted anal fistula treatment (VAAFT), a minimally invasive method, was introduced for adult patients in 2011. Objective To know the efficacy of

4. Surgical Outcome of Modified Karydakis Flap and Modified Limberg Flab in the Management of Sacroccygeal Pilonidal Disease: A Comparative Study
Abstract Introduction Sacrococcygeal pilonidal disease (SPD) is a chronic suppurative condition of the sacrococcygeal region causing chronic sinus tract or cyst. It is an acquired complex disease more common in young adult males, causing considerable morbidity and long periods of interruption in work or education. From simple conservative techniques to comp

5. Return to work after severe traumatic brain injury: further investigation of the role of personality changes
Objective: Longitudinal measurement invariance analyses are an important way to assess a test’s ability to estimate the underlying construct over time, ensuring that cognitive scores across visits represent a similar underlying construct, and that changes in test performance are attributable to individual change in cognitive abilities. We aimed to evaluat

7. The Covid-19 pandemic seen from the frontline
ABSTRACT COVID-19 disease caused by infection with the SARS-CoV-2 virus produces respiratory symptoms, predominantly of the upper airways, which can progress to pneumonia after 7 days with persistent fever, cough and dyspnea, and even develop a syndrome of acute respiratory distress (ARDS), multi-organ failure and death. Since COVID-19 disease was declared b

8. Project and Analysis of Quasi-Periodic PBG for Microstrip Antenna
Abstract In this work the influence of quasi-periodic distributions of air holes with 6, 12 and 6-fold modified symmetries, applied to the substrate of a rectangular microstrip patch antenna are analyzed. To validate the study, parameters such as S11 parameter, bandwidth, total gain, radiation pattern and electric field were investigated through computationa

10. ESTADO, TRANSPORTES E MERCADO DE TRABALHO: LIVRES, LIBERTOS E ESCRAVOS EM OBRAS PÚBLICAS NA PROVÍNCIA DE MINAS GERAIS NAS DÉCADAS DE 1830-1840
Resumo Durante as décadas de 1830 e 1840, o Governo Provincial de Minas Gerais investiu diretamente na construção da Estrada do Paraibuna. A intervenção viária exigiu a contratação de trabalhadores braçais e qualificados. Pretende-se neste estudo explorar o ajustamento de trabalhadores livres e libertos e o sistema de aluguel de escravos. Enfatiza-s
