13. Validação de metodologia para a caracterização química de bagaço de cana-de-açúcar
In this work, a methodology for the characterization of sugar cane bagasse was validated. Bagasse pre-treated with steam in a 5000 L reactor at a pressure of 15.3 kgf/cm², during 7 min, was used to test the methodology. The methodology consisted of the hydrolysis of the material with H2SO4 at 72% v/v, for the quantification of carbohydrates, organic acid, f

14. DESENVOLVIMENTO E OTIMIZAÇÃO DE METODOLOGIA PARA ANÁLISE DE ATRAZINA E SEUS PRODUTOS DE DEGRADAÇÃO POR CROMATOGRAFIA LÍQUIDA DE ALTA EFICIÊNCIA E ELETROFORESE CAPILAR
Atrazine is an herbicide widely used on crops of major economic relevance as corn and sugar cane. The widespread use of this herbicide can cause its accumulation or contamination of environmental matrices. In addition, the degradation products of atrazine also deserve attention. This study aims to develop methodology for the analysis of atrazine and its deri

15. Using energy dispersive X ray fluorescence (EDXRF) technique to evaluate the suspended particulate matter from Limeira city, State of São Paulo, Brazil / Utilização da técnica de fluorescência de raios X por dispersão em energia (EDXRF) na avaliação do material particulado em suspensão na cidade de Limeira - SP
The main objective of this work was to evaluate the chemical composition of the suspended particulate matter from the atmosphere of the city of Limeira, State of São Paulo, by energy dispersive X-ray fluorescence (EDXRF) technique. A stacker filter sampler was used to collect the fine (particles with aerodynamic diameter between 2.5 and 10 müm) and the gro

16. Phenolic and coumarin compounds: certification of an analytical method for the characeerization and quantification in cane spirits aged in barrels of different wood species / Compostos fenÃlicos e cumarinas: certificaÃÃo de um mÃtodo analÃtico para caracterizaÃÃo e quantificaÃÃo em aguardentes de cana envelhecidas em barris de diferentes espÃcies de madeira.
A aguardente de cana à uma bebida fermento-destilada largamente consumida no paÃs. Estima-se que sua produÃÃo seja de aproximadamente 1,5 bilhÃo de litros/ano, sendo o volume exportado representado por apenas 1% da produÃÃo. Diante desse cenÃrio, tem-se buscado cada vez mais formas alternativas para se agregar valor ao produto, sendo que o envelhecim

17. Casca de arroz processada via enzimólise como fonte de carbono para produção de celulose por Acetobacter xylinum / Rice husk processed with hidrolityc enzimes as source of carbon for the production of bacterial cellulose by Acetobacter xylinum
Bacterial cellulose (BC) has been applied in the electronic industry and in medicine as a wound dressing film. However, the high manufacturing cost limits its wide-scale use. To reduce the costs of the process and obtain a differentiated product, this work proposes the use of rice husk as a substrate for the production of BC, since it consists of minerals, c

18. A glycoprotein with anti-inflammatory properties secreted by an Aspergillus nidulans modified strain
Total RNA from lipopolysaccharide (LPS)-stimulated rat macrophages used to treat protoplasts from an Aspergillus nidulans strain originated the RT2 regenerated strain, whose culture supernatant showed anti-inflammatory activity in Wistar rats. The protein fraction presenting such anti-inflammatory activity was purified and biochemically identified. The scree

19. DESENVOLVIMENTO E VALIDAÇÃO DE MÉTODO FOSFORIMÉTRICO EM SUBSTRATO DE CELULOSE PARA DETERMINAÇÃO DE PIRENO E CRISENO / DEVELOPMENT AND VALIDATION OF THE PHOSPHORIMETRIC METHOD IN CELLULOSE SUBSTRATE TO DETERMINATION OF PYRENE AND CHRYSENE
In this work, solid surface room-temperature phosphorimetry (SSRTP) was used to develop ultra-trace and selective methods for determination of chrysene and pyrene in complex samples containing several other polycyclic aromatic hydrocarbons (PAHs). Both chrysene and pyrene were selected because they are classificated by the U.S. Environmental Protection Agenc

20. Identification, quantification and comparison between the chemical substances responsable of the irradiated pot still cachaça and comercial rum aromas / Identificação, quantificação e comparação das substâncias químicas responsáveis pelos aromas da cachaça de alambique e do rum comercial tratados pelo processo de irradiação
The irradiation process has being presented as an alternative technique in food preservation. When apply on beverages, radiation is mainly used for malt decontamination or sterilization of musts and had been proposed also to accelerate aging. Some confusion over rum and cachaça identities has arisen due to the internationalization of cachaça. This research

21. Ocorrência de carbamato de etila e sua formação em cachaça de alambique e em aguardente de cana-de-açúcar / Occurrence of ethyl carbamate and its formation in cachaça and in industrial sugar cane spirit
It was studied the influence of storage time in wood casks, in amber glass containers and in transparent glass bottles in the formation of ethyl carbamate in cachaça. It was also verified the occurrence of ethyl carbamate, volatile acidity and alcoholic degree levels in cachaça and in industrial sugar cane spirit, relating them to the Brazilian State where

22. Sugar metabolization of Saccharomyces cerevisiae with transporter of sucrose and different invertase activity / Metabolização de açúcares em linhagens de Saccharomyces cerevisiae com e sem transportador de sacarose e diferentes atividades de invertase
The aim of this work was to evaluate the metabolic profile in the utilization of sugars, using different yeast strains (BG-1, CAT-1, FLEISHMANN, PE-2, 1403-7A and LCM001) with different growth medium and also to analyze behavior and the invertase activities of these yeast strains during fermentative process with recycling, similar to the industrial process.

23. Development of thermal process otmized for mosto sugar canes in alcoholic fermentation / Desenvolvimento de processo termico otimizado para mosto de caldo de cana na fermentação alcoolica
In this research is proposed a thermal treatment process for sugar cane must with maximum retention of fermentable sugar (sucrose, glucose and fructose), to promote a thermal inactivation of its bacterial contaminants and therefore, those of alcoholic fermentation. With this objective were examined the thermo degradation kinetics of sucrose, glucose, fructos

24. Identificação das fontes de poluição atmosférica na cidade de São Carlos-SP.
The quality of the atmospheric air is of great importance for the health of the population. Among the quantifiable aspects of the air quality, one can find the particulate matter (PM) concentration in the atmosphere, whose fine (PM10) and ultra-fine (PM2.5) fractions have been extensively studied, as these particle size fractions are particularly damaging fo
