1. Modeling residual biomass from mechanized wood harvesting with data measured by forest harvester
Abstract: The lack of accurate models for estimating residual biomass in wood harvesting operations results in underutilization of this co-product by forestry companies. Due to the lack of this information, forestry operations planning, such as chipping and transport logistics, are influenced, with a consequent increase in costs. Thereby, the aim of this stu

3. Assessing environmental impacts using a comparative LCA of industrial and artisanal production processes: "Minas Cheese" case
This study uses the Life Cycle Assessment (LCA) methodology to evaluate and compare the environmental impacts caused by both the artisanal and the industrial manufacturing processes of "Minas cheese". This is a traditional cheese produced in the state of Minas Gerais (Brazil), and it is considered a "cultural patrimony" in the country. The high participation

5. Transformações da estrutura produtiva da região sul e restante do Brasil
This work aims to analyze and compare the production structure of the Southern Region and the Rest of Brazil. To achieve the objectives has been used the system input-output inter-regional of three southern states and the Rest of Brazil for the years 1999 and 2004, shared with the information contained in the National Household Sample Survey (PNAD) for 1999,

6. A hybrid methodology to solve the container loading problem with weight distribution and cutting problems
Transport of goods has represented an important role in economic development throughout the history and ship containerization brought great advantages. Its invention in mid-1950s brought down the cost of transport and reduced time for loading and unloading cargo. Consequently, it increased efficiency of port working and reduced handling cargo to hours instea

8. Metodologia para planejamento da colheita e transporte florestal utilizando geotecnologia e pesquisa operacional / Methodology for planning forest harvesting and transport using geotechnology and operations research.
Considering the current scenario in which the use of forest resources is growing quickly, it is necessary the use of techniques and tools to facilitate the short, medium and long run planning, thus facilitating the search for a more rational use of these precious resources, assisting and supporting the decision making. This study aimed to use the geographic

9. Análise experimental de vigas pré-formadas de concreto armado à flexão e ao cisalhamento / Experimental analysis of reinforced concrete preformed beams to bending and shear
Reinforced concrete preformed beams are structural elements which present a thin superficial precast concrete layer that defines their geometrical shapes. This superficial layer functions as a formwork that will be incorporated to the beam after the introduction of cast in loco concrete, which will consolidate the structure. This construction system presents

10. Relação entre empresas florestais e comunidades do entorno: proposta para superação de conflitos / Relations between forest companies and communities of around: proposal for overcoming of social conflicts
The work discuss social demands presents in the brazilian forestry, which posses a land concentrative model. The focus is on the irregular withdrawal of wood the forest plantings for the communities of around, that they demand for work and job. The methodology was based in the participant observation of the research action and in exploratory research. As wor

11. Análise técnica e econômica de um sistema de colheita florestal / Technical and economic analysis of a forest harvest system
Hand logging systems were the first adopted, mostly, in the exploitation of native forests, with no concern with the rationalization and productivity of such activities. In Brazil, the first activities of forest harvesting were carried out along the coast, at that time of discovery, when the main traded species was brazilwood. Machine selection and developme

12. Hidrocarbonetos policíclicos aromáticos no meio ambiente: diferenciação de fontes em sedimentos e metabólitos em bile de peixes
Many studies on environmental ecosystems quality related to polycyclic aromatic hydrocarbons (PAH) have been carried out routinely due to their ubiquotus presence worldwide and to their potential toxicity after its biotransformation. PAH may be introduced into the environmet by natural and anthropogenic processes from direct runoff and discharges and indirec
