RESUMO

Given the growth of domotics and home automation, there is a need to use smart devices that integrate energy management systems and enable the automation of the environment. Considering the need to study the relationship between the environmental parameters in which the equipment is located and the energy parameters, an Environmental Awareness smart Plug (EnAPlug) is proposed with the application of machine learning (Tiny ML).This article presents a demonstration of EnAPlug applied to a refrigerator for predictions on internal humidity and activation motor for 5 min-ahead prediction on its operation, i.e., turning on or off. The two models for forecasting humidity presented Root Mean Squared Error (RMSE) results of 0.055 and 0.058 and a Coefficient of determination (r2 score) of 0.97 and 0.99, respectively. For the motor activation prediction, the results obtained were an accuracy of 94.74% and 94.84%, an F1 score of 0.97 for OFF, 0.94 for ON for Forecast 1 and 0.97 for OFF and 0.93 for ON for Forecast 2. Although the prototype does not have commercial purposes, what differs from existing smart plugs is the option to store data locally. The results are promising, as it allows for better energy management with implementation of machine learning.

RESUMO

In this study, we present a novel approach for the exfoliation of titanium nitride (TiN) powders utilizing a rapid, facile, and environmentally friendly non-thermal plasma method. This method involves the use of an electric arc and nitrogen as the ambient gas at room temperature to generate ionized particles. These ionized species interact with the ceramic crystal of TiN, resulting in a pronounced structural expansion. The exfoliated TiN products were comprehensively characterized using transmission electron microscopy, X-ray diffraction, and Raman spectroscopy. Remarkably, the cubic crystal structure of TiN was effectively retained, while the (200) crystal plane d-spacing increased from 2.08 to 3.09 Å, accompanied by a reduction in crystallite size and alterations in Raman vibrational modes. Collectively, these findings provide compelling evidence for the successful exfoliation of TiN structures using our innovative non-thermal plasma method, opening up exciting possibilities for advanced material applications.

RESUMO

Methane is an abundant resource and the main constituent of natural gas. It can be converted into higher value-added products and as a subproduct of electricity co-generation. The application of polymer electrolyte reactors for the partial oxidation of methane to methanol to co-generate power and chemical products is a topic of great interest for gas and petroleum industries, especially with the use of materials with a lower amount of metals, such as palladium complex. In this study, we investigate the ideal relationship between cis-[6-(pyridin-2-yl)-1,3,5-triazine-2,4-diamine(dichloride)palladium(II)] (Pd-complex) nanostructure and carbon to obtain a stable, conductive, and functional reagent diffusion electrode. The physical and structural properties of the material were analyzed by Fourier transform infrared (FT-IR) and Raman spectroscopies, transmission electron microscopy (TEM), and X-ray powder diffraction (XRD) techniques. The electrocatalytic activity studies revealed that the most active proportion was 20% of Pd-complex supported on carbon (m/m), which was measured with lower values of open-circuit and power density but with higher efficiency in methanol production with reaction rates of r = 4.2 mol L-1·h-1 at 0.05 V.

RESUMO

The application of solid electrolyte reactors for methane oxidation to co-generation of power and chemicals could be interesting, mainly with the use of materials that could come from renewable sources and abundant metals, such as the [6,6'- (2, 2'-bipyridine-6, 6'-diyl)bis (1,3,5-triazine-2, 4-diamine)](nitrate-O)copper (II) complex. In this study, we investigated the optimal ratio between this complex and carbon to obtain a stable, conductive, and functional reagent diffusion electrode. The most active Cu-complex compositions were 2.5 and 5% carbon, which were measured with higher values of open circuit and electric current, in addition to the higher methanol production with reaction rates of 1.85 mol L-1 h-1 close to the short circuit potential and 1.65 mol L-1 h-1 close to the open circuit potential, respectively. This activity was attributed to the ability of these compositions to activate water due to better distribution of the Cu complex in the carbon matrix as observed in the rotating ring disk electrode experiments.

RESUMO

This study aimed to characterize the cases of tuberculosis (TB) co-infected with the human immunodeficiency virus (HIV) in Minas Gerais State, Brazil, after the notification sheet modification, and to verify the association between the new variables and the treatment outcome. It is an analytical cross-sectional study with TB/HIV cases notified in the year 2016 to the Brazilian Information System for Notifiable Diseases (Sistema de Informação de Agravos de Notificação). Descriptive statistics, chi-square test, and multiple correspondence analysis were performed to verify the association between the outcome, ageand associated diseases. Of the 180 cases, most were male (75.6%) between 30 and 49 years old (63.3%), mixed ethnicity (black and white) (49.4%), 94.4% had the Acquired Immunodeficiency Syndrome (AIDS) and 60.6% had pulmonary TB. The molecular test was not performed at the time of diagnosis in 70.5% of the cases. Homeless people (4.4%) and prisoners (3.9%) featured prominently among the special populations. People between 40 and 49 years old without concurrent diseases were cured in 40.0% of the cases; 18.9% abandoned the treatment due to smoking, drug abuse and mental illness in the age group between 20 and 29 years old. The deaths were associated with the age group between 30 and 39 years old and the occurrence of AIDS. The results have shown that the groups considered vulnerable (drug users, smokers and people with mental illness) abandoned the treatment, the notification upon death from AIDS in adults was late and some treatments were inadequate. The epidemiological surveillance, prevention and assistance strategies towards cases of TB/HIV must be improved in order to achieve the goal of the Brazilian National Plan to end Tuberculosis as a Public Health Problem until 2035 in the state.

RESUMO

INTRODUCTION: Over 30 years after the acquired immunodeficiency syndrome epidemic, several strategies have been implemented to verify the trend of the infection, the profile of the affected individuals, and the impact of prevention and control measures, with notification of asymptomatic carriers being the most recent measure. This study aimed to verify the geographic distribution of human immunodeficiency virus/acquired immunodeficiency syndrome and analyze the association between case definition criteria, sociodemographic data, and clinical aspects of the disease in the State of Minas Gerais between 2007 and 2016. METHODS: In this ecological and analytical study, 35,349 cases of human immunodeficiency virus/acquired immunodeficiency syndrome reported in the State of Minas Gerais between 2007 and 2016 were analyzed. The data were analyzed using multiple correspondence factor analysis, time series analysis, descriptive statistics, and spatial distribution of the cases by macro-region. RESULTS: The majority of the patients were brown-skinned individuals, alive, diagnosed with human immunodeficiency virus/acquired immunodeficiency syndrome on the basis of the criteria adapted from the Centers for Disease Control and Prevention, and living in municipalities with more than 50,000 (80.5%) inhabitants. Between 2007 and 2016, there was an increase in the number of criteria used for diagnosing human immunodeficiency virus. By contrast, a consequent decrease was observed in the number of criteria used for defining cases, which were adapted from the Centers for Disease Control and Prevention, Rio de Janeiro/Caracas, and for identifying AIDS-related deaths. Young people aged between 13 and 29 years, individuals whose education level is compatible with the observed age, and homosexual men were associated with the HIV+ criterion. CONCLUSIONS: Out study showed that after the mandatory notification of human immunodeficiency virus-positive cases in 2014, there was a decrease in other criteria for defining human immunodeficiency virus/acquired immunodeficiency syndrome cases and changes in the profile of people living with human immunodeficiency virus/acquired immunodeficiency syndrome.

RESUMO

RESUMO Introdução: As doenças cardiovasculares têm sido associadas à presença de desordens musculoesqueléticas. A dor presente nessas comorbidades pode constituir fator limitante para prática de exercício. No entanto, não foram encontrados instrumentos que proporcionem mensuração mais criteriosa e com informações precisas, que possam ser facilmente utilizados na prática clínica. Neste sentido, torna-se relevante a construção e validação de um instrumento mais específico para obtenção de informações detalhadas sobre a presença e gravidade desses sintomas e sua interferência nos aspectos funcionais, custos e fatores psicossociais, em diferentes momentos, resultando em uma avaliação mais precisa. Com isso, profissionais da equipe multidisciplinar envolvidos nos programas de reabilitação cardiopulmonar e metabólica (RCPM) podem utilizá-lo na prática clínica e abrir mão de estratégias especificamente direcionadas a essas afecções. Objetivo: Construir e validar um instrumento para avaliação da dor musculoesquelética em repouso e durante o exercício em participantes de RCPM. Métodos: Foram realizados procedimentos teóricos, empíricos e analíticos. A análise de concordância entre avaliadores (juízes) foi verificada pelo teste W de Kendall, a consistência interna dos itens, por meio do alfa de Cronbach e a reprodutibilidade e estabilidade de medidas, por meio do teste e reteste (coeficiente de correlação intraclasse - CCI e coeficiente de Kappa). Resultados: A concordância entre avaliadores foi significativa (p = 0,001) e a consistência interna apresentou valores satisfatórios (alfa de Cronbach > 0,82). O teste-reteste sinalizou boa reprodutibilidade e estabilidade de medidas (CCI < 0,40 e Kappa < 0,60). Conclusão: O questionário para avaliação da dor musculoesquelética em praticantes de exercício (Q-ADOM) mostrou-se válido, reprodutível e confiável para ser utilizado na avaliação da dor musculoesquelética de participantes de RCPM.

ABSTRACT Introduction: Cardiovascular diseases have been associated with the presence of musculoskeletal disorders. The presence of pain in these comorbidities may be a limiting factor for exercise practice. However, no instruments were found that provide more thorough measurement and accurate information that can be easily used in clinical practice. In this sense, the construction and validation of a more specific instrument becomes relevant to obtain detailed information on the presence and severity of these symptoms and its interference in the functional aspects, costs, and psychosocial factors at different times that result in a more precise evaluation. Thus, professionals of the multidisciplinary team involved in cardiopulmonary and metabolic rehabilitation (CPMR) programs can use it in clinical practice and put aside the strategies specifically directed to these conditions. Objectives: To construct and validate an instrument to assess musculoskeletal pain at rest and during exercise in participants of CPMR. Methods: Theoretical, empirical, and analytical procedures were performed. The concordance analysis among evaluators (judges) was verified by Kendall's W test, the internal consistency of the items through Cronbach's alpha, and reproducibility and stability measures through the test and retest (intraclass correlation coefficient - ICC and Kappa coefficient). Results: The concordance among evaluators was significant (p=0.001) and showed satisfactory internal consistency values (Cronbach's alpha > 0.82). The test-retest indicated good reproducibility and stability measures (ICC<0.40 and Kappa<0.60). Conclusion: The questionnaire for the evaluation of musculoskeletal pain in exercise practitioners (Q-ADOM) proved to be valid, reproducible, and reliable to be used in the evaluation of musculoskeletal pain in CPMR participants.
