1. Consumption of microcomputers in Brazil: an analysis using datas from PNAD 2001 to 2007 and POF 2002-2003 / O consumo de microcomputadores no Brasil: uma análise utilizando dados das PNADs de 2001 a 2007 e da POF 2002-2003
O consumo domiciliar de microcomputadores cresceu de forma acelerado nos últimos anos. Apesar de grupos com determinadas características socioeconômicas terem um consumo maior de computadores, o consumo vem aumentando em todos os grupos. Ou seja, mesmo com diferenças grandes, o consumo de computadores não é mais uma exclusividade dos mais ricos, dos ma

2. Desenvolvimento de procedimentos em fluxo para a determinação de Captopril, Dipirona e Paracetamol envolvendo multicomutação e inibição da quimiluminêscencia / Development of procedures in flow injection for the determination of captopril, dipirona and paracetamol involving multicommutation and inhibition of chemiluminescencia
In the present work, analytical procedures were developed using the multicomutação concept and inhibition of the chemilumenescence for the pharmaceuticals determination, such as, captopril, dipirona and paracetamol. For the control of the analysis module and acquisitions of data a microcomputer was used Pentiun 233 MHz equipped with an electronic interface

3. "Development of the instrumentation and automatic analytical procedures for spectrophotometric determination of surfactants in waters" / "Desenvolvimento de instrumentação e procedimentos analíticos automáticos para a determinação espectrofotométrica de tensoativos em águas"
"In this work, development of the instrumentation and automatic analytical procedures for spectrophotometric determination of surfactants in waters employing the multicommutation concept were proposed. Aiming to system miniaturization, reduction of reagents consumption and effluents generation, solenoids micro-pump and solenoids pinch valves were used for th

4. Development of automatic procedures for the determination of ethanol, glycerol and tartaric acid in wine using multicommutation in flow. / Desenvolvimento de procedimentos automáticos para determinação de etanol, glicerol e ácido tartárico em vinho empregando multicomutação em fluxo.
In the present work, flow systems for the determination of ethanol, glycerol and tartaric acid in wine without previous sample treatment are described. The flow system were based on multicommutation and controlled by microcomputer allowing that the analytic procedures were accomplished automatically without the intervention of the operator. For ethanol deter

5. Development of automatic procedures for the determination of 3-hidroxybutyrate, glucose and cholesterol in animal blood serum using in flow multicommutation. / Desenvolvimento de procedimentos automáticos para a determinação de 3-hidroxibutirato, glicose e colesterol em soro de sangue animal empregando multicomutação em fluxo.
In the present work, in flow injection systems were developed for the determination of important metabolic parameters, such as 3-hydroxybutyrate, glucose and cholesterol in animal blood serum. The analysis modules were developed based on the multicommutation concept, whose main characteristics favor the processing of many samples. For this, three-way solenoi

6. Controle fiscal e os tributos sobre o valor adicionado: o caso do ICMS / Fiscal control and the taxes on value added: the case of icms
Many discussions have been made around of tax problem in Brazil and in the world, particularly in European Economic Community, resultant of the consolidation and improvement of European Common Market. In this context is elevated the aspects related on the value added, particularly those concerning to moment of incidence, on origin (production) or on destiny

7. Desenvolvimento de sistemas automatizados de adições padrão e eliminação de interferencias em analise espectrofotometricas de rochas, minerais e ligas pela aplicação do metodo generalizado de adições padrão
Correction for the chemical, physical, spectra and/or matricial interferences by standard addition methods generally requires preparation and addition to the sample of a serie of standard solutions. If manual addition procedures are employed, they, besides being tedious, usually involve a relatively large consumption of reagents and samples and a low analyti
