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. Avaliação por análise de DRX da influência do beneficiamento de moagem na atividade pozolânica da cinza do bagaço de cana-de-açúcar
RESUMO É crescente o reaproveitamento e utilização de resíduos em matrizes de base cimentícia, no intuito de um destino adequado, por apresentarem propriedades pozolânicas, bem como, na perspectiva da redução do consumo de cimento Portland. Neste trabalho foram produzidas cinzas a partir do beneficiamento de moagem da cinza do bagaço de cana-de-aç�

3. Effect of partial replacement with thermally processed sugar cane bagasse on the properties of mortars
ABSTRACT Sugar cane bagasse is a residue of the sugar-alcohol industry, and its main destination is represented by burning boilers for power generation. The bagasse cogeneration of power produces a sugar cane bagasse ash (SCBA) residue that does not have a useful destination. Ashes are commonly studied as pozzolan in Portland cement production. International

4. Study on the pozzolanic activity of sugar cane straw ash produced using different pretreatments
This work systematically describes a laboratory study on different pretreatments of sugar cane straw to produce pozzolanic ash. Two procedures were used to accelerate the hydrolysis of celluloses and hemicelluloses and remove metallic impurities present in significant levels in sugar cane straw: hot water washing and acid leaching. Proximate analysis by ther

5. Fósforo em cronossequência de cana-de-açúcar queimada no cerrado goiano: análise de ácidos húmicos por RMN de 31P
The aim of this study was to identify, with the use of 31P NMR spectroscopy, organic P species in humic acids (HA) in samples from Oxisol cultivated in chronosequence with sugar cane, pasture and Cerrado. The main forms of P-type found were orthophosphate, monoester-P (phosphate sugars) and P-diester (orthophosphate). The 31P NMR technique proved capable of

6. Elementos traço em material particulado atmosférico de uma região agroindustrial do sudeste do Brasil
Trace element concentrations were measured in atmospheric particulate matter collected in 2009 and 2010, in a Brazilian region influenced by pre-harvest burning of sugar cane crops. For coarse particles, high concentrations of Al, Fe, K and Ca suggested that re-suspended soil dust was the main source of aerosol trace elements, subsequently confirmed by XRD a

7. 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

8. Estudo espaço-temporal da mortalidade e morbilidade por doenças respiratórias no município de Botucatu, São Paulo / Space-time study of moratality and morbidity for respiratory diseases in teh city of Botucatu, São Paulo
An ecological study conducted between the years 2003 to 2010 with monthly data on the number of mortality and morbidity from respiratory diseases, areas for monoculture of sugar cane and spatial distribution of outbreaks of fires in Botucatu, São Paulo. Data were extracted, respectively, of databases DATASUS AND THE Institute for Space Research (INPE). The

9. Efeito de materiais particulados em sistemas modelos de biomembranas / Effect of Particulate Material on Biomembrane Model Systems
This work presents some of the properties of mimetic systems of pulmonary surfactants (PS) composed of dipalmitoylphosphatidylcholine (DPPC) and DPPC/cholesterol and their interactions with particulate material (PM) originated from the burning of sugar cane leaves which is known by clinical studies as an injurious agent of the respiratory airways. The PM des

10. PHOSPHORUS DYNAMICS AND ORGANIC MATTER IN QUARTZIPSAMMENT CULTIVATED WITH SUGAR CANE HARVESTED WITHOUT BURNING / DinÃmica do fÃsforo e da matÃria orgÃnica em neossolo cultivado com cana-de-aÃÃcar colhida sem queima
Na cultura da cana-de-aÃÃcar, por razÃes econÃmicas e ambientais, a queima da palhada, feita para facilitar a colheita e o transporte, vem sendo substituÃda pela colheita mecanizada. Sabe-se que a manutenÃÃo da palhada sobre o solo influencia a dinÃmica da Ãgua, nutrientes e matÃria orgÃnica, mas seus efeitos ainda nÃo sÃo suficientemente conhec

11. Desenvolvimento e produção de cana-de-açúcar em sistema sob palhada
Due to environmental constraints, lack of manpower and the search for better efficiency, the harvesting of sugar cane tends to be mechanized, causing large amount of straw is available in this new system. There are benefits to soil and culture provided by this residue. However, it was discussed what amount would be sufficient to promote these benefits and wh

12. Emissão de gases de efeito estufa na obtenção do etanol de cana-de-açúcar: uma avaliação considerando diferentes cenários tecnológicos em Minas Gerais
This paper presents a greenhouse gas emissions (GHG) assessment of the agricultural and industrial processes of sugar cane ethanol production in Minas Gerais. The assessment was performed by considering different technological scenarios related to the agricultural and industrial processes. The GHG balance takes into account CO2, CH4 and N2O direct emissions
