1. Avaliação da resistência à compressão e da absorção de água de concretos utilizados após o tempo máximo de mistura e transporte especificado pela NBR 7212 / Evaluation of compressive strength and water absorption of concrete used after the maximum time of mixing and transport specified by NBR 7212
The Brazilian standard NBR 7212 (ABNT, 1984), for execution of ready-mixed concrete, specifies the maximum time for concrete to be discharged (used) completely in 150 minutes. The usage time of the concrete is due to reactions of the cement hydration and slump loss that occurs with fresh concrete, a normal phenomenon defined as the loss of fluidity along the

2. Modelo de decisão para a programação de entrega de concreto produzido em centrais. / A decision model for the problem of scheduling concrete delivery produced in concrete batch plants.
This paper addresses the problem of scheduling concrete delivery produced in concrete batch plants. Such scheduling comprises the decisions of which center should serve each customer and what time each delivery vehicle should be loaded, so as to maximize the total marginal revenue of the system. Vehicle loading capacity constraints per center, fleet availabi

3. Avaliação da qualidade de concretos produzidos em centrais dosadoras, misturados em caminhão betoneira e de concretos produzidos em centrais misturadoras / Evalution of quality of concrete produced in metering plant mixes in truck mixer and concret produced in mixed plant
Em razão do pouco número de estudos relacionados ao processo de produção do concreto dosado em central, no que tange ao tipo de mistura empregada, esta pesquisa busca contribuir com a avaliação da qualidade de concretos produzidos em centrais misturadoras e centrais dosadoras. O objetivo principal do trabalho foi o de verificar se a forma de mistura do

5. Nouns and verbs are retrieved with differently distributed neural systems.
In a task designed to elicit the production of verbs, the patients known as AN-1033 and Boswell consistently produced the correct target words, performing no differently from normal controls. However, in a similar task designed to elicit the production of nouns, both patients performed quite defectively, and their scores were many SDs below those of controls

6. Trade-offs in producing patient-specific recommendations from a computer-based clinical guideline: a case study.
This case study explored 1) how much online clinical data is required to obtain patient-specific recommendations from a computer-based clinical practice guideline, 2) whether the availability of increasing amounts of online clinical data might allow a higher specificity of those recommendations, and 3) whether that increased specificity is necessarily desira
