1. AN INVESTIGATION OF THE HEAT TRANSFER PERFORMANCE OF DUAL IMPROVED INTERMIG IMPELLERS IN A STIRRED TANK WITH AN INNER HEATING COIL
Abstract The heat transfer process in a stirred tank of diameter T=0.5m equipped with dual-layer improved Intermig impellers and helical coils was investigated by experiment and numerical simulation methods. The temperature field, the temperature boundary layer lateral to the coil and the heat transfer coefficient were measured at different rotational speeds

2. FUZZY CONTROL CHART FOR MONITORING MEAN AND RANGE OF UNIVARIATE PROCESSES
ABSTRACT The control chart introduced by Shewhart is one of the most important quality control techniques used to detect special causes. Real world data are complicated to interpret since they involve a certain level of uncertainty that may be linked to human subjectivity or measurement device limitations. Fuzzy set theory can deal with such uncertainty and

3. A Implantação do Sistema de Monitoramento e Avaliação da Secretaria Estadual de Saúde do Distrito Federal (SES/DF)
Resumo Por meio da criação do Sistema Único de Saúde (SUS), os processos de planejamento ganham importância intrínseca para a formulação de políticas públicas de saúde e para subsidiar a tomada de decisões, a implementação de ações e a obtenção de resultados. Como as ferramentas de planejamento são fundamentais para orientar a gestão, é

4. Evaluation of the Genetic Screening Processor for the Performance of Newborn Screening Tests
Abstract The collection of dried blood spots (DBSs) on filter paper has been a powerful tool in newborn screening (NBS) programs and in other fields. However, filter paper has been associated with some level of imprecision due to the filter paper matrix effect. In order to minimize measurement variations, these interferences should be evaluated by NBS assays

6. Flow Analysis: Looking Back and Forward
Flow analysis changed significantly the way of performing chemical analysis by (i) mechanization of analytical procedures in a continuous flowing stream with minimal sample intercontamination; (ii) analytical measurements without attaining chemical equilibria, thus increasing the applicability of kinetic methods and allowing the exploitation of non-quantitat

7. A Comparative Study of Cartesian and Delta 3D Printers on Producing PLA Parts
The additive manufacturing processes emerged at the end of the last century and became popular by low-cost 3D printers. The most used printers work on a cartesian configuration, but recently were launched delta machines. These 3D printers use a more complex control system due to their trajectories generation but may present some advantages over the cartesian

8. Sinais de fundo em análise instrumental: uma discussão essencial em cursos de graduação
Understanding instrumental analysis is essential for obtaining reliable analytical results required by chemists in a variety of research areas and industrial activities. All instrumental techniques involve undesirable background (BG) signals originated either from concomitants in the sample or by spurious (e.g. electrical or optical) effects intrinsically re

9. Estudo da corrosão localizada da liga de alumínio 7475-T761 por espectroscopia de impedância eletroquímica global e local em meio de sulfato de sódio. / Localized corrosion study of aluminum alloy 7475-T761 in sulfate medium using global and local electrochemical impedance spectroscopy.
Aluminum alloys used in the aerospace industry with structural purpose exhibit a complex microstructure due to thermal and mechanical treatments they are submitted for improving their strength. The microstructure of these alloys is characterized by the presence of a great number of intermetallic (IM) particles, the electrochemical activity of which is differ

10. Diseño de sistemas de medición de desempeño de proveedores: experiencias de un caso de estudio
The evaluation of suppliers’ performance is important for organizations because of the imperative role they play in the supply chains and the importance that purchasing functions have due to the outsourcing of activities which are not part of the company’s know-how. There is a need to work on the identification of practical problems concerning the design

12. Knowledge effect on firm performance in manufacturing and service firms
This thesis seeks to examine the difference between manufacturing and service firms with respect to the effects of knowledge on performance, and the influence of market turbulence in this relationship. Empirical data, resulting from a survey, was collected from more than 1,206 firms, involving several sectors. Two samples were analyzed, one with 334 manufact
