ABSTRACT Non-destructive tests that use the principle of wave propagation have the potential to predict the mechanical properties of wood while still in the field, if the variables of this process are known. This work aimed to estimate the modulus of elasticity to static bending of Eucalyptus sp. wood, using two non-destructive techniques: ultrasound and stress wave. For this, 60 specimens with nominal dimensions of 2.5 x 2.5 x 57.5 cm (tangential x radial x longitudinal) were used, being in equilibrium humidity. The non-destructive tests were carried out using an ultrasound and a stress wave equipment, while the destructive static bending tests were carried out in a universal testing machine. The experimental results showed that the elastic modulus obtained by the non-destructive techniques were superior to that obtained by the destructive technique. The adjusted mathematical models presented standard error of the estimate (Syx) of 11.39 and 10.78%. There was a positive mean correlation between the static and dynamic module. Stress wave and ultrasound techniques can be used to estimate the modulus of elasticity of Eucalyptus sp.

RESUMO Os ensaios não destrutivos que utilizam o princípio de propagação de ondas têm potencial para predizer as propriedades mecânicas da madeira ainda em campo, se conhecida as variáveis deste processo. Este trabalho teve o objetivo de estimar o módulo de elasticidade à flexão estática da madeira de Eucalyptus sp., por meio de duas técnicas não destrutivas: ultrassom e stress wave. Para tal foram usados 60 corpos de provas com dimensões nominais de 2,5 x 2,5 x 57,5 cm (tangencial x radial x longitudinal), estando na umidade de equilíbrio. Os testes não destrutivos foram realizados por meio de um equipamento de ultrassom e um de ondas de tensão, enquanto que os testes destrutivos de flexão estática foram realizados em uma máquina universal de ensaios. Os resultados experimentais mostraram que os módulos de elasticidade obtidos pelas técnicas não destrutivas foram superiores à obtida pela técnica destrutiva. Os modelos matemáticos ajustados apresentaram erro padrão da estimativa (Syx) de 11,39 e 10,78%. Logo, houve correlação média positiva entre o módulo estático e dinâmico. As técnicas de ondas de tensão e ultrassom podem ser empregadas com o intuito de estimar o módulo de elasticidade da madeira de Eucalyptus sp.

ABSTRACT Objective: This study aimed to compare the influence of a high carbohydrate meal versus high-fat meal on the oxidation of substrates during an exercise incremental test. Materials and methods: Ten untrained male subjects underwent two days of the protocol. Randomly, they received a high carbohydrate meal or a high-fat meal, receiving the other one in the next protocol. On both days, they performed an incremental treadmill test, with heart rate and maximal oxygen consumption to estimate the oxidation of substrates. Results: The high-fat meal showed an increase in the absolute amount of oxidized fat along with the incremental test (P < 0.05; effect size = 0.9528), and a reduction in the respiratory exchange ratio at low intensities (P < 0.05; effect size = 0.7765). Conclusions: The meals presented no difference when compared to maximum oxidation point of substrates, the oxidation rate of substrates over time, and heart rate. A pre-test high-fat meal in untrained individuals was shown to be a modulating factor of total oxidized fats throughout the exercise, although it did not exert a significant effect on the rate of this oxidation over time.

Abstract Background: Diseases of the circulatory system are the leading cause of illness and death in the world population. Objective: Estimate the prevalence of high risk for coronary events (HRC) and associated factors in the Brazilian adult population. Method: This is a cross-sectional study, based on data from the National Health Survey 2013. The association of this condition with sociodemographic, health condition, and habits and lifestyle was evaluated for individuals as in HRC, according to the first stratification phase of the I Brazilian Directive of Cardiovascular Prevention. Statistical analysis was performed in three stages: descriptive; bivariate; and multiple analysis. Sampling weights and design effect of the complex sampling plan were considered, using the survey library of the statistical program R, version 3.2.2. Results: The prevalence of HRC in the Brazilian population was 11.06% (95%CI 10.83–11.29). A higher prevalence of HRC was observed with advancing age, in individuals living in the Central-South, who self-rated their health as poor/very poor, former smokers, and individuals with systemic arterial hypertension. Conclusions: The Brazilian population presented a high prevalence of HRC and, thus, has a more than 20% risk of an acute coronary event in the next ten years, if prevention and control measures are not taken.

Resumo Introdução: As doenças do aparelho circulatório representam a principal causa de adoecimento e mortes na população mundial. Objetivo: Estimar a prevalência de alto risco para evento coronário (ARC) e os fatores associados na população adulta brasileira. Método: Estudo transversal, com base nos dados da Pesquisa Nacional de Saúde 2013. Para os indivíduos classificados em ARC, segundo a primeira fase de estratificação da I Diretriz Brasileira de Prevenção Cardiovascular, avaliou-se a associação dessa condição com variáveis sociodemográficas, condição de saúde e hábitos e estilo de vida. A análise estatística foi realizada em três etapas: descritiva, bivariada e múltipla. Consideraram-se os pesos amostrais e o efeito de desenho do plano de amostragem complexo, utilizando-se da biblioteca survey do programa estatístico R, versão 3.2.2. Resultados: A prevalência de ARC na população brasileira foi de 11,06% (IC95% 10,83–11,29). Observou-se maior proporção de ARC com o avançar da idade, em indivíduos residentes no centro-sul, que autoavaliaram a saúde como ruim/muito ruim, ex-fumantes e hipertensos. Conclusões: A população brasileira apresentou alta prevalência de ARC e, assim, possui mais de 20% de risco de um evento coronário agudo nos próximos dez anos, caso medidas de prevenção e controle não sejam tomadas.

Abstract: En Pt

Objectives: To identify the prevalence and factors associated with work-related stress and Burnout syndrome among nursing professionals working in oncology. Methods: This is a cross-sectional study done with 231 nursing professionals who worked at a High Complexity Oncology Center in the city of Rio de Janeiro, Brazil, from December 2013 to June 2015. Work-related stress was assessed using the Workplace Stress Scale and Burnout syndrome by the Maslach Burnout Inventory. Results: The prevalence of Work-Related Stress of moderate/intense intensity was 75.8% and 38.9% of professionals had Burnout Syndrome. There was an increase in the prevalence of Work-Related Stress with advancing age [40-49, PR:1.61 (95%CI:1.01-2.55) and ≥ 50 years, PR:1.78 (95%CI: %:1.10-2.90)], with a positive history of accident [PR:1.29 (CI95%:1.06-1.60)] and physical or verbal aggression [PR:1.50 (CI95% :1.24-1.82)] during hospital work. The presence of Burnout syndrome was also associated with these variables, in addition to self-reported stress [PR:1.14 (95%CI:1.05-1.23)].  Conclusion: Work-related stress and Burnout syndrome were associated with antecedents related to the work environment and age, showing common variables in the occurrence of these comorbidities.

Resumo O objetivo deste estudo foi analisar a tendência temporal da mortalidade por suicídio em mulheres nos estados do Nordeste do Brasil. Trata-se de um estudo ecológico de uma série temporal estratificada por estados do Nordeste do Brasil de 1996 a 2018, com dados extraídos do Sistema de Informações sobre Mortalidade (SIM). A tendência temporal foi avaliada por regressão binomial negativa (valores de p≤0,05). Houve uma proporção maior de mortes em mulheres negras e pardas (73,9%), solteiras (57,3%), com o local da morte ocorrendo em casa (53,4%). Suspensão e estrangulamento se destacaram como o meio de perpetração (47,5%). A maioria dos estados apresentou tendência temporal ascendente, com exceção de Pernambuco, Rio Grande do Norte, Sergipe e Maranhão, que apresentaram tendência estável (p>0,05). Uma tendência temporal ascendente foi identificada na análise dos óbitos por suicídio em mulheres em cinco estados do Nordeste brasileiro entre 1996 e 2018. Assim, as informações apresentados podem apoiar no planejamento e nas tomadas de decisões para prevenção do suicídio entre mulheres no Nordeste brasileiro.

Abstract The objective of this study was to analyze the temporal trend of suicide mortality in women in the states of Northeastern Brazil. This is an ecological study of a time series stratified by states in Northeast Brazil from 1996 to 2018, with data extracted from the Mortality Information System (SIM). The temporal trend was evaluated by negative binomial regression (p values≤0.05). There was a higher proportion of deaths in black and brown women (73.9%), single (57.3%), with the place of death occurring in the home (53.4%). Hanging and strangulation stood out as the perpetration means (47.6%). Most states showed an upward temporal trend, except for Pernambuco, Rio Grande do Norte, Sergipe and Maranhão, which showed a steady trend (p>0.05). An upward temporal trend was identified in the analysis of deaths by suicide in women in five states in northeastern Brazil between 1996 and 2018. The information presented can support planning and decision-making for the prevention of suicide among women in northeastern Brazil.

Resumo Introdução Os homicídios femininos apresentam elevada magnitude e transcendência no Nordeste brasileiro. Objetivo Analisar a evolução temporal da mortalidade por homicídio feminino no estado do Rio Grande do Norte (RN) e suas regiões de saúde nos anos 2000. Método Trata-se de um estudo ecológico que utilizou regressão binomial negativa para a análise de tendência. Resultados A taxa de mortalidade média no período foi de 5,08 óbitos por 100.000 mulheres, com as maiores taxas observadas na Região Metropolitana (5,92 óbitos) e Mossoró (5,60 óbitos). A maior proporção de óbitos ocorreu em solteiras, perpetrados por arma de fogo e localizados no domicílio. Verificou-se uma tendência de aumento da mortalidade em todas as faixas etárias até os 49 anos e na Região Metropolitana de João Câmara. Também se constatou tendência de alta na taxa de mortalidade por homicídios por arma de fogo em todas as regiões de saúde, exceto Caicó e Pau dos Ferros, onde houve estacionariedade nas taxas. Conclusão O estado do Rio Grande do Norte e suas regiões de saúde apresentam taxas de homicídios femininos semelhantes aos países com maior violência contra as mulheres, indicando a necessidade de maiores investimentos na rede de proteção à mulher em situação de violência doméstica.

Abstract Background Female homicides present high magnitude and transcendence in the Northeast region of Brazil. Objective To analyze the temporal evolution of mortality due to female homicide in the state of Rio Grande do Norte and its health regions between 2000 and 2016. Method Ecological study using negative binomial regression for trend analysis. Results The average mortality rate for the period analyzed was 5.08 deaths per 100,000 women, with the highest rates observed in the metropolitan region (5.92) and in the municipality of Mossoró (5.60). Most of the deaths were of unmarried women, with the use of firearms, and occurred at home. There was an upward trend in mortality in all age groups up to age 49 and in the metropolitan region of João Câmara. An upward trend was also observed in the mortality rate of firearm homicides in all health regions of the state, except for Caicó and Pau dos Ferros, where these rates showed a stationary trend. Conclusion The state of Rio Grande do Norte and its health regions show female homicide rates similar to those of countries with the greatest violence against women, indicating the need for greater investments in the protection network for women in situations of domestic violence.

ABSTRACT The objective of this study was to compare different alternatives to estimate the stem volume of individual trees in four different forest formations in the Minas Gerais state, Brazil. The data were obtained in a forest inventory procedure performed by the Minas Gerais Technological Center Foundation. The stem volumes were computed by the Smalian expression up to the outside bark diameter equal to 4 cm. The volume data of outside bark, diameters (DBH) and total heights were used to fit a Schumacher and Hall equation for each forest formation, considering the structures of the linear fixed and mixed models. Next, 100 Multilayer Perceptron artificial neural networks (ANN) were trained in a supervised manner. In addition, we evaluated eight support-vector machine regression (SVMR). The criteria to evaluate the performance of all the alternatives studied were: the correlation between the observed and estimated volumes, the square root of the mean square error and the frequency distribution by percentage relative error class. After the analyzes, all the alternatives were verified to estimate the volume of the individual trees in the different forest formations. Although the alternatives presented close statistics in the validation process, the graphical analysis of the error distribution showed greater precision of the estimates of the mixed linear models for the four formations. Given the results, it is concluded that there is no absolute superiority of one alternative over the others, and that all of them should be evaluated to find the one which best describes or explains the dataset.

Abstract: En | Text: En | PDF: En

Abstract The objective of this study was to assess and compare two methodologies to predict the mortality of individual trees in a seasonal semi-deciduous forest located in the municipality of Viçosa, Minas Gerais, Brazil. The data came from 10 permanent plots and were randomly divided into two groups: fitting (6 plots) and validation (4 plots). When assessing Methodology 1, the mortality was considered a dichotomous variable in a logistic model, assuming a value of 1 for a dead tree and 0 for a living tree. In Methodology 2, the mortality probability was estimated by the group of trees for each plot and for each measurement interval. After the analysis, it was observed that Methodology 2 provided more consistent mortality estimates when compared to the mortality estimated by Methodology 1.

Abstract: En | Text: En | PDF: En

Gadodiamide (Gd-DTPA-BMA) is a gadolinium (Gd) chelate composed of two carboxylate groups of diethylenetriaminepentaacetic acid (DTPA) and two amide groups (BMA). Gd complexes are the most widely used contrast agents in nuclear magnetic resonance. Furthermore, our research group has demonstrated the potential of liposomes containing Gd-DTPA-BMA for cancer therapy. The aim of this study was to develop and validate a chemometric-assisted method by hydrophilic interaction liquid chromatography (HILIC) for determination of Gd-DTPA-BMA in liposomes. The chromatographic conditions obtained were: Sequant® ZIC®-HILIC Merck (150 × 4.6 mm, 3.5 µm, 100 Å) column, mobile phase composed of 5 mmol L-1 ACN/NH4FA, pH 4.5 (60:40 v/v) at 0.6 mL min-1, injection volume of 20 µL, temperature of 30 ºC, and detection at 210 nm. The linear range was of 40 to 120 nmol mL-1. The use of chemometrics allowed obtaining optimal chromatographic parameters, in terms of signal-to-noise ratio, resolution, and asymmetry.

RESUMO Objetivou-se aplicar e avaliar métodos para estimar múltiplos volumes em uma Área de Manejo Comunitário, localizada na Floresta Nacional do Tapajós. Foram cubadas, rigorosamente, 516 árvores-amostra de 21 espécies comerciais, todas com 50 cm > dap < 160 cm. Utilizaram-se o modelo único para múltiplos volumes (análise de regressão) proposto por Leite et al. (1995) e redes neurais artificiais (RNA) para a estimativa do volume de fuste e galhos. Após os resultados preliminares usando o método de regressão, optou-se por separar os dados em três estratos, considerando a relação volume de galhos em razão do volume de fuste comercial. As equações geradas por estratos apresentaram melhoria nos ajustes, mas os resultados obtidos pela RNA foram melhores que os pelas equações de regressão.

ABSTRACT The objective of this study was to apply and evaluate methods to estimate multiple volumes in a Community Management Area, located in the Tapajós National Forest. 516 sample-trees were rigorously scaled of 21 commercial species, all with 50 cm > dbh < 160 cm. The unique model for multiple volumes (regression analysis) proposed by Leite et al. (1995) and Artificial Neural Networks (ANN) were used to estimate the volume of stem and branches. After preliminary results using the regression method, it was decided to stratify the data into three parts, considering the relationship between volume of branches and volume of commercial stem. The equations generated showed improvement in the adjustments. However, the results with ANN were better than the ones generated by regression equations.
