Abstract Innovation is directly related to economic growth and competitiveness. Some barriers can be observed during the process of implementing innovation in civil construction, such as the lack of understanding related to the innovation benefits in the sector. Considering the importance of agents involved in construction as promoters of the innovation process, it is necessary to identify their perceptions about the innovation concept. The present study addresses how to capture the perception of innovation by the civil construction internal agents and allow the communication of innovation diagnosis in a company. The framework developed is divided into three stages: (i) development of the structure through theoretical review; (ii) rounds of applications are carried out in a case study and in the academic environment, generating adjustments to the questionnaire and infographic; and (iii) development of the final version of the framework and the suggested actions for each category). The framework proposal proved to be efficient for diagnosing the perception of innovation agents, in addition to bringing practical results on the basis for decision making with companies.

Resumo Anecessidade de inovar está diretamente relacionada ao crescimento econômico e à competitividade. Algumas barreiras são observadas no processo de implantação da inovação na construção civil, a exemplo da falta de entendimento dos benefícios da inovação no setor. Diante da importância dos agentes envolvidos na construção como facilitadores do processo de inovação, é necessário identificar suas percepções acerca do tema.

A ferramenta desenvolvida está dividida em três etapas: (i) desenvolvimento da estrutura através da revisão teórica; (ii) aplicações em estudo de caso e no meio acadêmico, gerando ajustes ao questionário e ao infográfico; e (iii) desenvolvimento da versão final da ferramenta e de sugestões de ações por cada categoria). A proposta da ferramenta mostrou-se eficiente para o diagnóstico acerca da percepção dos agentes da inovação, além de trazer resultados práticos no embasamento para tomada de decisão nas empresas.

Resumo As atividades de controle de produção e qualidade realizadas no canteiro de obras são baseadas em procedimentos manuais ou em diferentes tecnologias de coleta automática de dados. Um grande problema é esses controles são muitas vezes aplicados de forma isolada. Existem oportunidades para melhorar o desempenho das obras, integrando sistemas de controle de qualidade e produção utilizando sistemas digitais e considerando conceitos e princípios da Produção Enxuta. Este artigo descreve uma estrutura conceitual que possibilita a integração da produção e do controle de qualidade em canteiros de obras, considerando a combinação do BIM e do Last Planner System™ (LPS). Esta pesquisa baseou-se em dois estudos empíricos, realizados em empresas que desenvolvem e constroem projetos de edifícios residenciais. A principal contribuição do estudo é a capacidade o modelo proposto de superar as limitações dos softwares comerciais disponíveis para fazer frente à flexibilidade exigida pelo LPS. Os resultados indicaram que a estrutura conceitual proposta permite que um feedback oportuno seja fornecido aos gerentes de produção e que os modelos BIM sejam rapidamente atualizados com monitoramento do progresso e dados de qualidade do produto.

Abstract Current production and quality control activities performed on-site are based either on manual procedures or on different automatic data collection technologies. A major problem in these controls is that they are often applied in isolation. Therefore, there are opportunities for improving the performance of construction projects by integrating quality and production control systems supported by digital systems and considering concepts and principles from Lean Philosophy. This article describes a conceptual framework that make it possible to integrate production and quality control in construction sites, considering the combination of BIM and the Last Planner System™ (LPS). This investigation was based on two empirical studies, carried out in companies that develop and build residential building projects. The main contribution of the study is the ability of the model to surpass the limitations of commercial software available to cope with the flexibility demanded by LPS. The results indicated that the proposed framework enables timely feedback to be provided to production managers, and BIM models to be quickly updated with progress monitoring and product quality data.

Resumo A gestão de sistemas pré-fabricados demanda uma intensa troca de informações entre a fábrica e a obra, de forma a sincronizar a fabricação, as operações logísticas e o processo de montagem, principalmente em ambientes engineer-to-order, no qual o nível de incerteza tende a ser alto. A literatura sugere o uso de Building Information Modeling (BIM) para facilitar o compartilhamento de informações e apoiar a tomada de decisões, assim como a aplicação de conceitos e princípios da Produção Enxuta. Particularmente em relação ao processo de montagem, o BIM 4D pode ser utilizado para simular algumas operações, apoiando o planejamento e controle da produção. O presente artigo propõe um conjunto de diretrizes para a utilização do BIM 4D e conceitos e princípios da Produção Enxuta para apoiar a gestão logística do processo de montagem de sistemas pré-fabricados em concreto do tipo engineer-to-order. Foi adotada a abordagem metodológica da Design Science Research, tendo por base um estudo empírico realizado em uma empresa que fornece estruturas pré-fabricadas de concreto. As principais contribuições do trabalho referem-se o uso de BIM 4D para padronizar as operações logísticas e para a gestão de informações relacionadas ao status do sistema.

Abstract The management of prefabricated building systems demands an intense exchange of information between the the plant and the construction site, in order to synchronize the production of components, logistic operations and site assembly, especially in engineer-to-order environments, in which the degree of uncertainty tends to be high. The literature suggests the use of Building Information Modeling (BIM) to facilitate the sharing of information and to support decision-making in this type of environment, as well as the application of Lean Production concepts and principles. Particularly in relation to the assembly process, 4D BIM can be used to simulate some operations, supporting production planning and control. This paper proposes a set of guidelines for using 4D BIM and Lean Production concepts and principles to support logistics management for the assembly process in engineer-to-order concrete prefabricated systems. Design Science Research was the methodological approach adopted in this investigation, which was based on an empirical study carried out in a company that delivers prefabricated concrete structures. The main contributions of this study are related to the use of BIM 4D for standardizing logistics operations, and for managing information related to system status

Abstract The present study aimed to evaluate the potential of forest species for herbicide phytoremediation. The experiment was conducted in a greenhouse with a randomized block design and a 2x3x3 factorial scheme, using two soils (Red-Yellow Latosol - RYL and Quartzarenic sandy soil - QN), three herbicide solutions (without herbicides/water, 2,4-D and atrazine), and three forest species (Cecropia hololeuca, Eucalyptus grandis x Eucalyptus urophylla and Hymenea coubaril), with four replications. After the experiment, Cucumis sativus was cultivated in order to investigate possible herbicide residues in the soils. The evaluated forest species reduced atrazine and 2,4-D residues in most treatments, except for the Jatobá (Hymenaea coubaril ) cultivated in the RYL soil. Eucalyptus was the species that showed the greatest tolerance to herbicide action, demonstrating the potential for phytoremediation of atrazine and 2,4-D. Cecropia hololeuca and Hymenaea coubaril presented the greatest potential for 2,4-D and atrazine, respectively.

RESUMO Para aumentar a eficiência no controle de plantas daninhas é comum o uso em dessecação da mistura dos herbicidas glifosato e 2,4-D. Objetivou-se, neste trabalho, avaliar o efeito residual da aplicação desses dois herbicidas sobre o desenvolvimento de plantas de milho em solos de diferentes texturas. O experimento foi conduzido em casa de vegetação, no ano de 2015, em delineamento inteiramente casualizado, no esquema fatorial 2 x 2 x 7, sendo dois solos (Latossolo Vermelho Amarelo e Neossolo Quartzarênico), duas épocas de aplicação dos herbicidas (5 e 10 dias antes da semeadura do milho) e sete doses dos herbicidas (dose recomendada de glifosato; dose recomendada de 2,4-D; mistura das doses recomendadas de glifosato e 2,4-D; duas, dez e cinquenta vezes as doses recomendadas em mistura e uma testemunha), com quatro repetições. Após a emergência das plantas de milho foram avaliados os seguintes parâmetros: fitotoxicidade, altura de plantas, clorofilas a e b, massa fresca e seca da parte aérea e massa seca da raiz. Em geral, ocorreu menor efeito residual no Latossolo Vermelho Amarelo em todas as doses dos herbicidas e no intervalo de 10 dias entre a aplicação e a semeadura.

ABSTRACT To increase the efficiency in the control of weeds, it is common the use of a mixture of the herbicides glyphosate and 2,4-D in the desiccation. This paper aimed to evaluate the residual effect of these two herbicides on the development of maize plants, in soils of different textures. The experiment was conducted in a greenhouse, in 2015, in a completely randomized design in a 2 x 2 x 7 factorial scheme, corresponding to two soils (Red Yellow Latosol and Quartzarenic Neosol), two herbicide application times (5 and 10 days before maize sowing) and seven doses of herbicides (recommended dose of glyphosate, recommended dose of 2,4-D; mixing the recommended doses of glyphosate and 2,4-D; two, ten and fifty times the recommended doses in admixture; and one control), with 4 replicates. After emergence of maize plants, the following variables were evaluated: phytotoxicity, plant height, chlorophyll a and chlorophyll b, shoot fresh and dry matter and root dry matter. In general, there was lower residual effect on the Red Yellow Latosol at all the doses of the herbicides and in the interval of 10 days between the desiccation and sowing.

Abstract The relation between oxidative stress and inflammation induced by diseases and exercise has increased the interest in the benefits of antioxidant supplements in the improvement of health and physical and mental performance. The aim of this study was to evaluate the effectiveness of açai gel in reducing oxidative stress in individuals engaged in physical activities as well as their acceptance. Sensory evaluation was performed to determine its acceptability and the biochemical parameters related to immune profile and biomarkers of muscle, liver and oxidative stress, with and without the use of gel were evaluated. The appearance, sweetness and overall impression of the açai gel were considered good. It was observed a significant increase in CK enzyme, without the gel as well as the oxidative stress biomarkers, it was observed that the MDA (with and without gel) a significant increase (p < 0.05). Through biochemical evaluation, it is concluded that the gel provided protection for some of parameters studied, since it modulated the immunological parameter reducing the lymphocyte activity and muscular stress. However, more studies must be carried out with a larger number of individuals to confirm the gel functionality.

A nivel mundial, un tercio de las partes comestibles de los alimentos producidos para el consumo humano se desperdicia, siendo importante la generación de propuestas para el uso sostenible de los mismos. El objetivo de este trabajo fue determinar la influencia de cuatro dietas, a base de salvado de arroz, en tres cantidades y tres densidades larvales sobre la duración del periodo larval, porcentaje de viabilidad larval y peso larval de Chrysomya megacephala. Los Resultados indican que la duración del periodo larval y el porcentaje de viabilidad larval fueron favorecidos con el incremento de salvado de arroz en la dieta. En contraste, el peso larval se redujo con este incremento. En relación con la densidad larval, 5 larvas/g de dieta presentó el mayor porcentaje de viabilidad larval, sin presentar efectos significativos sobre la duración del periodo y peso larval. La duración del periodo larval y el porcentaje de viabilidad larval no difirieron al incrementar la cantidad de dieta, mientras que el peso larval aumentó favorablemente. En relación con la interacción de los factores, la duración del periodo larval disminuyó conforme se incrementó la densidad larval en la dieta con mayor contenido de salvado de arroz, y el peso larval aumentó conforme se incrementó la cantidad de dieta. Finalmente, 5 larvas/g de dieta es la densidad ideal de C. megacephala, el peso larval aumenta con la cantidad de dieta y la duración del periodo larval es inversamente proporcional a la densidad larval en la dieta con mayor contenido de salvado de arroz.

Globally, a third of the edible parts of food produced for human consumption are wasted, therefore it is important the generation of proposals for the sustainable use thereof. The objective of this investigation was to determine the influence of four diets, based in rice bran, in three quantities and three larval densities on the duration of larval period, larval viability and larval weight of C. megacephala. The results indicate that the duration of larval period and percentage of larval viability were favored when the content of rice bran in the diet was increased. In contrast, the larval weight was decreased. In relation with larval density, 5 larvae/g of diet presented the greatest percentage of larval viability, without significant effects on the duration of larval period and larval weight. The duration of larval period and larval viability did not differ by increasing the quantity of diet, while the larval weight increased favorably. In relation with the interaction of factors, the duration of larval period decreased as the larval density increased, in the diet with the greatest content of rice bran, and the larval weight increased as the quantity of diet increased. Finally, the density of 5 larvae/g of diet is the ideal density of C. megacephala, the larval weight increases with the quantity of diet, and the duration of larval period is inversely proportional to the larval density in the diet with the greatest content of rice bran.

O objetivo deste trabalho foi avaliar os efeitos de cultivares transgênicas de algodoeiro que expressam as proteínas Cry1Ac e Cry1F, nos parâmetros biológicos da lagarta falsa-medideira (Chrysodeixis includens). Lagartas neonatas foram alimentadas durante toda a fase larval com folhas de cultivares transgênicas e de suas isolinhas convencionais. Na cultivar Nuopal (Bollgard I) (Cry1Ac), 62% das lagartas sobreviveram e se transformaram em pupas normais. A cultivar FM 975 (WideStrike) (Cry1Ac e Cry1F) é letal para lagartas de primeiro instar, com 100% de mortalidade.

The objective of this work was to evaluate the effects of transgenic cotton cultivars expressing the Cry1Ac and Cry1F proteins, on the biological parameters of soybean looper (Chrysodeixis includens). Neonate larvae were fed during the entire larval phase with leaves from transgenic cultivars and their conventional isolines. In the Nuopal (Bollgard I) cultivar (Cry1Ac), 62% of larvae survived and became normal pupae. The FM 975 (WideStrike) cultivar (Cry1Ac and Cry1F) is lethal to first-instar larvae, with 100% mortality.

Os estudos da atratividade e da seleção de parceiros têm recebido atenção especial dentro da perspectiva da Psicologia Evolucionista, mostrando influências tanto de fatores físicos quanto de fatores não-físicos. Neste estudo, utilizou-se de fotografias da face de homens e mulheres, pré-julgados como medianamente atraentes, desconhecidos dos participantes, associadas a uma história neutra ou que envolvia comportamento de infidelidade, para avaliar a influência de informação sobre o comportamento de infidelidade na avaliação da atratividade de indivíduos do sexo oposto. Os resultados mostraram diferenças significativas apenas quando as mulheres avaliavam fotografias de homens, atribuindo menor atratividade a homens associados à história de infidelidade. As diferenças entre homens e mulheres podem refletir mecanismos adaptativos para a avaliação da atratividade do sexo oposto relacionados às diferenças nos custos reprodutivos. Esses resultados são discutidos sob a perspectiva da Psicologia Evolucionista.

Studies of attractiveness and mate selection have received special attention within the Evolutionary Psychology perspective, showing influences from both physical and non-physical factors. In the present study, we used photographs showing faces of men and women, pre-judged as median attractive people, unknown to the participants, associated with neutral stories or stories involving infidelity behavior, to investigate the influence of information about infidelity behavior on the evaluation of attractiveness of opposite sex individuals. Results showed significant differences only when women evaluated men's photographs, attributing lower attractiveness to men associated with a story of infidelity. The sex differences found may represent adapted mechanisms to evaluate opposite sex attractiveness related to differences in reproductive costs. These results are discussed mainly under the Evolutionary Psychology perspective.
