1. THE SUCCESS OF THE BRAZILIAN ALCOHOL PROGRAM (PROÁLCOOL) - A DECADE-BY-DECADE BRIEF HISTORY OF ETHANOL IN BRAZIL
ABSTRACT The National Alcohol Program (Proálcool) was a strategic policy of the Brazilian government to replace petroleum-based fuels with alcohol (ethanol). Based on the review, we can choose the 1960s as a start point for a leap in development. Over the 500 years of sugarcane history in Brazil, the crop enters the second decade of the 21st century with ex

2. Trajetórias De Acumulação De Capacidades Inovadoras, Mecanismos De Aprendizagem E Fatores Organizacionais Relativos A Atividades Em Gestão De Projetos: Estudo De Caso Comparativo Inter-Empresarial Na Indústria De Bens De Capital E De Celulose E Papel No Brasil
Over the last 40 years there has been a profusion of studies about the ccumulation of technological capacities in firms from developing economies. However, there remain few studies that examine, on a combined basis, the relationship among: the trajectories of technological capacities accumulation; the underlying learning mechanisms; and, the implications of

3. Evaluation of the wood quality of species Acacia crassicarpa, Acacia mangium, Eucalyptus nitens, Eucalyptus globulus and Populus tremuloides / Avaliação da qualidade da madeira das espécies Acacia crassicarpa, Acacia mangium, Eucalyptus nitens, Eucalyptus globulus e Populus tremuloides
As madeiras utilizadas para produção de polpa celulósica podem ser divididas em dois grupos em função da fibra: folhosas (fibra curta) e coníferas (fibra longas), as espécies de folhosas são destinadas especialmente a papéis de escrita e impressão. As principais espécies de folhosas utilizadas para produção de polpa de fibra curta em outros paí

4. Analise termodinamica de um sistema de cogeração com gaseificação de licor negro / Termodynamic analysis of a cogeneration system with blak liquor gasification
The pulp and paper industries generate most part of energy for self consumption burning two different fuels: biomass and black liquor, which is more used than the first one. This industrial sector has been used cogeneration systems, to produce electric energy from the combustion of these fuels. In the last years an increase in the production of the industrie

6. Friend or foe? Ecological Modernisation in Brazil
Ecological modernisation (EM) is a theory that proposes participation in decisionmaking, trust in science and technology, and preference for preventative measures, as strategies to simultaneously achieve environmental and economic objectives. The main objective of this thesis is to empirically assess the feasibility of EM in Brazil. This assessment is based

7. Vibrações ultra-sônicas: uma tecnologia alternativa ao refino da celulose branqueada kraft de eucalipto / An alternative technology to the refining of the bleached kraft pulp in eucalyptus
Some technological conditions were studied at laboratory level, so allowing to evaluate the application of the ultrasonic vibrations upon the bleached pulp in eucalyptus as a refining form, as well as their effects on the development of the paper properties. Initially some preliminary tests were accomplished in order to verify either the best time and the po

8. Utilização de rejeito fibroso industrial da polpação kraft de eucalipto para produção de papéis / Utilization of industrial eucalyptus kraft pulping fibrous residue for paper production
Searching for alternatives to optimize the use of forest resources, this work was developed to provide new forms of utilizing residue from the screening sector of the eucalyptus Kraft pulping industry. For residue recovery, mechanical systems were used to eliminate and disintegrate impurities to optimize the quantitative level of residue use. The study was d
