    The present work evaluated the influence of assemblies other than preheating in the welding process obtained by coated electrode, using high strength and low alloy steel SAR 80T as the base metal and the AWS E7018 electrode as the addition metal. In order to prevent cracks, preheating and interpassing for low alloy steel was performed. Depending on the way the preheating equipment is installed, it may take more or less time to reach the preheat temperature. Different assembly arrangements for top joints were evaluated, aiming at cost reduction, in addition to evaluations of the mechanical properties of the joint. Visual testing, ultrasound, micrography, macrography and cross-sectional traction were performed. The results obtained were considered acceptable and showed that there was an influence on time, cost of preheating and resistance to impact

    É amplamente reconhecido que elevada concentração de renda prevalece no Brasil e que a posição socioeconômica dos segmentos sociais exerce influência nas condições de vida e saúde, incluindo a qualidade da alimentação. Medir a magnitude das desigualdades sociais no perfil da qualidade alimentar da população brasileira. Analisaram-se dados da amostra de 60.202 adultos da Pesquisa Nacional de Saúde de 2013. Foram estimadas as prevalências de indicadores de qualidade alimentar segundo sexo, raça/cor, renda, escolaridade e posse de plano de saúde. Razões de prevalência foram estimadas por meio de regressão múltipla de Poisson. Maior prevalência de consumo de alimentos saudáveis foi verificada no sexo feminino, entre os brancos e no grupo de melhor nível socioeconômico. Entretanto,para alguns alimentos considerados não saudáveis, como doces, sanduíches, salgados e pizzas, também foi observada maior prevalência nos segmentos sociais mais favorecidos, nas mulheres e nos brancos, expressando a concomitância de escolhas alimentares saudáveis e não saudáveis. Desigualdade de maior magnitude foi observada quanto à comparação do consumo de leite desnatado e semidesnatado segundo renda (razão de prevalência - RP=4,48). Além de expressiva desigualdade social no perfil alimentar dos brasileiros, foram detectados perfis mistos, incluindo alimentos saudáveis e não saudáveis, sinalizando a necessidade de monitoramento e de intervenções de promoção de alimentação saudável que levem em conta as desigualdades sociais e as contradições no consumo alimentar222CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQnão tem817122/2015High income concentration prevails in Brazil and socioeconomic status influences living and health conditions, including dietary quality. Objective: To measure the magnitude of social inequalities in the food quality profile of the Brazilian population. We analyzed data from 60,202 adults who participated in the 2013 National Health Survey. The prevalence of indicators of food quality was estimated according to gender, ethnicity, income, schooling, and health insurance. We calculated prevalence ratios using multiple Poisson regression. Healthy food consumption was more prevalent among females, white people, and individuals with higher socioeconomic status. However, we also found a higher prevalence of some foods considered unhealthy, such as sweets, sandwiches, snacks, and pizzas, among the most favored social segments, in women, and white people, expressing the concomitance of healthy and unhealthy eating habits. The comparison between the consumption of skim and low-fat milk according to income (prevalence ratio – PR = 4.48) presented the most significant difference. In addition to the expressive social inequality identified in the Brazilian food profile, mixed patterns were detected, including healthy and unhealthy foods. These results point out the need for monitoring and promoting healthy eating habits, taking into account the social inequalities and contradictions concerning food intakeMinistério da Saúd

    This paper presents a fuzzy multicriteria group decision making approach for evaluating and selecting information systems projects. The inherent subjectiveness and imprecision of the evaluation process is modeled by using linguistic terms characterized by triangular fuzzy numbers. A new algorithm based on the concept of the degree of dominance is developed to avoid the complex and unreliable process of comparing fuzzy numbers usually required in fuzzy multicriteria decision making. A multicriteria decision support system is proposed to facilitate the evaluation and selection process. An information systems project selection problem is presented to demonstrate the effectiveness of the approach
