14. AN APPROXIMATE COST-INTEGRATED MODELLING APPROACH TO CROSS DOCK DESIGN
ABSTRACT Cross docking is a form of operating break-bulk freight terminals in which the receiving products are not stocked but, instead, the incoming cargo is internally transferred to be immediately shipped in distribution trucks. With this approach, inventory costs and lead-times are significantly reduced. In this work, an approximate, continuous, non-stat

15. THE BRAZILIAN EXPERIENCE WITH ETHANOL FUEL: ASPECTS OF PRODUCTION, USE, QUALITY AND DISTRIBUTION LOGISTICS
Abstract The reduction in the availability of fossil fuel increased the search for alternative fuel sources (for example, ethanol). In the Brazilian market, light duty vehicles can be fueled with gasohol (18 up to 27.5 %v/v of anhydrous ethanol in gasoline) and/or hydrous ethanol. To minimize the risk of water-induced phase separation of gasoline-ethanol ble

16. Pine Harvest Impact on Soil Structure of a Dystric Cambisol (Humic)
ABSTRACT Traffic of heavy machinery at harvest and log extraction causes structural degradation of the soil, but studies on the effects of forest harvesting on soils with high organic matter content and exchangeable Al are scarce. The objective of this study was to evaluate the effect of mechanized forest harvesting operations on a Dystric Cambisol (Humic) w

20. 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

23. Estimativa da emissão de poluentes pelo setor de transporte e análise das ocorrências de doenças respiratórias na área de proteção ambiental do Sistema Cantareira / Estimation of pollutant emissions by sector and transport analysis of respiratory diseases in the area of environmental protection System Cantareira
The global energy matrix is mainly composed by fossil fuels which when burned release air pollutants that affect the environment and human health. In this sense, monitoring health problems related to air pollution is important because it reinforces the need for change in national and international energy policies. This thesis presents a discussion on air pol
