1. Mecanização e intensificação do trabalho no corte de cana do CAI canavieiro do estado de São Paulo
Assuming that the work is the central category in the production process, the relationship between the recent modernization, in special in the harvesting activities, and the manual harvesting work intensification were studied in the Sugarcane Agroindustrial Complex of São Paulo State. The work intensification, which involves high energy expenditure by the w

2. Utilização da cinza do bagaço da cana-de-açúcar como agregado miúdo em concretos para artefatos de infraestrutura urbana
Brazil is the main sugarcane world-producer and it is the leader in all segments (sugarcane, sugar and alcohol). The waste consisting of sugarcane bagasse is produced at the end of grinding process and it is used to generate energy through burning in boilers. At the end of burning, the ashes of bagasse are often thrown into environment improperly. In this co

3. Evaluation of activated vegetal charcoal and vegetal polymer on the detoxification of the sugarcane hemicellulosic hydrolysate for biotechnological production of xylitol / Avaliação do carvão vegetal ativado e polímero vegetal na destoxificação do hidrolisado hemicelulósico de bagaço de cana-de-açúcar para a produção biotecnológica de xilitol
The increasing search for ethanol fuel in order to reduce the dependence and to promote the substitution of fossil fuels will contribute to higher accumulation of sugarcane bagasse in the environment. This biomass that in Brazil is a by-product of the sugar-alcohol mills, although it has been used for the generation of energy in the sugar and alcohol product

4. Modelagem do planejamento agregado da produção em usinas cooperadas do setor sucroenergético utilizando programação matemática e otimização robusta
The main concern of this work is related to the development of an aggregate production planning model of a cooperative society of sugar and alcohol milling companies. This mathematical model is based on a hierarquical approach between the annual planning problem of the cooperative and the tactical planning horizon of the sugarcane mills. In the cooperative l

5. A reprodução do espaço da pequena produção rural familiar em Canguaretama/RN
This study aimed to explore the process of reproduction of space from the small family farm production in the municipality of Canguaretama, specifically focused on foodstuffs of plant origin, seeking to understand the changes in agrarian space canguaretamense and its impact on small family farms the last 35 years. Since colonization, during the seventeenth c

6. Avaliação de coeficientes de rendimento e modelagem do processo fermentativo de produção de etanol
The yield ethanol (hP) is one of the most important parameters to be evaluated in the industrial process of alcohol fermentation. Because most plants neither present a reasonable level of automation, nor perform frequent analytical measures during the batch, the hP is currently calculated by methodology based on by-products formed in the process. Such calcul

7. Prospective analysis of the pattern of expansion of the sector sucroenergético Brazil: an application of probabilistic models with data-georeferenciated / Análise prospectiva do padrão de expansão do setor sucroenergético brasileiro: uma aplicação de modelos probabilísticos com dados georeferenciados
With expectations of a growing international market for biofuels, where Brazil would be a natural leader in the ethanol, several questions arise regarding the sustainability of Brazilian ethanol expansion: what would be the environmental, social and economic inpacts of sugarcane expansion in a scenario of significant ethanol exports? What regions would be mo

8. Um modelo baseado em seleção de processos e dimensionamento de lotes para o planejamento agregado da produção em usinas de açúcar e álcool.
The main concern of this work is related with the development of an aggregate production planning model of a sugar and alcohol milling company. This mathematical model is based on the process selection model and the production lotsizing model, and aims to help the decision makers in the production planning and control process of determining the quantity of s

9. Otimização da capacidade de instalações sucro-alcooleiras / Optimization of the capacity of sugar and alcohol plants
This study is about optimizing sugar-cane transportation and delivery logistics in the sugar and alcohol industry, based on waiting-queue models following a model for optimizing production, using linear programming, with the objective of increasing the total profit resulting from the sale of the products and by-products: sugar-cane bagasse, filter cake, stil

10. Avaliação exergética dos efluentes do processo industrial do álcool / Exergetic assessment of effluents in the industrial alcohol process
In the production of ethyl alcohol as a fuel, the sugar and alcohol industry captures large volumes of water for steam generation, for cooling and as part of the process, generating large amounts of effluents. Using the energy produced by the burning of bagasse in the furnace for the transformation of water into steam, the industry generates its own electric

11. A desregulamentação e o desempenho do complexo sucroalcooleiro no Brasil.
This work analyzed the evolution of the relation between the sugar and alcohol complex and the State from 1975 to 2002, when there was a change from public intervention, marked by Proálcool, to a new situation, in which deregulation is proposed. We attempted to interpret the main political and economical stipulators of the process, as well as describe the w

12. Mapeamento do palhiço enfardado de cana-de-açúcar (Saccharum spp.) e do seu potencial energético. / Sugar cane (Saccharum spp.) bailed trash yield and energetic potencial mapping.
Brazil is a developing tropical country with abundant potential for production of biomass. The sugar cane is primarily produced to obtain alcohol and sugar. Currently the sugar cane fields are burned as a pre-harvest practice. If such practice is abandoned, the trash (green leaves, tops and straws left after harvesting) could be collected and used for vapor
