The present study evaluated a photovoltaic system with a tracker of two daily positions located at the State University of Ceará (UECE), Fortaleza, Ceará. A 50 Wp rated power system with a two-position manual tracker daily was compared with a fixed system at 0º in the horizontal plane. The results of the three stages of the experiment were collected in 16 days, in July/2021 and August/2021. Several data were collected, such as solar irradiation, electricity generated, and battery charge status.

A beleza é uma preocupação constante de grande parte da população. A busca por uma boa aparência não é um privilégio dos séculos XX e XXI. Estudos mostram que, há muitos anos, ser belo sempre esteve na lista de prioridades da população. Entretanto, com o passar do tempo, o padrão de beleza foi sofrendo alterações. O objetivo desse estudo é pesquisar na literatura disponível sobre a utilização de corrente elétrica como uma estratégia para aumentar o fortalecimento muscular em mulheres.

Bariatric surgery is an alternative intervention for individuals with morbid obesity, a pathology that compromises lung function due to its inflammatory and systemic character. As it is an upper abdominal wall surgery, it generates changes in the individual's respiratory mechanics, making it necessary to use Non-invasive Mechanical Ventilation. This study is a systematic review that aims to investigate the respiratory repercussions of positive pressure therapy in the postoperative period of bariatric surgery.

This quantitative descriptive and analytical study aimed to identify which sociosanitary and epidemiological factors are associated with the onset of severe COVID-19. Data from 2,702 Brazilian nationals aged 18 and over were collected online using Google® Forms from June 24 to July 1, 2020. Association between diagnosis of COVID-19 andsociosanitary and epidemiological variables was assessed. In all, 656 participants had had COVID-19. Cases were categorized into mild and severe, with 45.7% (300) of the cases classified as severe.

The main objective of this article was to investigate some facts, deeds, myths and truths about the Capoeirista from Santo Amaro, Bahia, Manuel Henrique Pereira, popularly known as Besouro Cordão de Ouro and/or Besouro Mangagá. To do so, we used the basic exploratory biographical case study method with a qualitative approach. As for the techniques of data collection and information generation, the interview technique was applied, always aided by the field diary instrument. Concomitantly, research was also carried out in public archives where primary documentary sources were consulted.

The COVID-19 pandemic impelled many universities worldwide to temporally shut the door on in-person education. As a matter of fact, some education institutions opted to keep up the remote classes. Engineering programs, however, rely on educational technology laboratories to conduct practical activities. In this way, virtual experiments and a remote laboratory for synchronous classes were proposed as educational technologies in the Mechatronics Engineering undergraduate program.

In the undergraduate Brazilian courses, the approach to experimental statistics is reduced in the menu so that professors have time to explain all the content. However, some methodologies are not used, such as Welch's ANOVA and the van der Waerden test. The objective of this work is to present these two techniques that are neglected, however, can contribute to more robust analyzes in other experiments. Using the R program four treatment variables were simulated and the proposed tests were applied.

Introduction: heart because it is an organ possessing its own ritmicity, needs to be regulated moment-to-moment to respond adequately to stimuli both endogenous and exogenous to the organism and such modulation is exerted by action of the Autonomous Nervous System (ANS) by two antagonistic pathways, the sympathetic trunk and the vagal parasympathetic, which together dictate the ritmicity and the natural variability of the frequency (HRV).

Introdução: No início do ano de 2020, uma nova pandemia se espalhou rapidamente pelo mundo: a Covid-19. A Organização Mundial da Saúde (OMS) declarou, em 30 de janeiro de 2020, que o surto da Covid-19 era uma emergência de saúde pública e a caracterizou como uma pandemia. Entre os ambientes hospitalares, a UTI é definida como agressivo e ameaçador, pois evidencia o risco de morte do paciente. Dessa forma, a presente investigação tem por objetivo refletir acerca do impacto da pandemia de covid-19 na qualidade de vida de profissionais de enfermagem intensivistas.

A hipertensão é a doença cardiovascular mais frequente e favorece diretamente para IAM e AVC’s que são as maiores causas de morte no Brasil. Para que haja redução da mortalidade é necessário a adequada aferição da PA. Objetivo: Avaliar o conhecimento teórico-prático entre os profissionais de saúde na Atenção Primária sobre a medida indireta da PA e realizar uma intervenção educativa. Métodos: Estudo quase experimental, amostra por conveniência.
