1. Electronic tongue system to evaluate flavor of soybean (Glycine Max (L.) Merrill) genotypes
An electronic tongue system was tested as a fast and efficient analytical tool for flavor evaluation of soybean genotypes. Grain samples of 25 soybean lines were analyzed using 0.25 g of milled samples added to 100 mL of distilled water and mixing for one minute on a magnetic stirrer. An aliquot (50 mL) from the filtered liquid was used for the analysis on a

2. Estudo dos resíduos eletroeletrônicos de uma prestadora de services do setor naval, com vistas ao gerenciamento ambiental. / Study of a naval segment Company e-waste, to environmental management.
Esta pesquisa usou o estudo de caso para analisar os resíduos eletroeletrônicos gerados em uma Empresa prestadora de serviços atuante no setor naval. Após breve reflexão sobre a relação homem-natureza, apresenta-se o conceito de resíduos sólidos e suas classificações, introduzindo-se dados que embasam o impacto dos eletroeletrônicos na geração

4. Metodologia para avaliação da interferencia eletromagnetica em equipamentos eletromedicos de apoio a procedimentos cirurgicos
The Electromagnetic Interference (EMI) has been appointed as one of the causes of equipment malfunction and hazards occurred in electrosurgical procedures. The identification of source-victim relationships and parameter quantification of these interferences consists in a very important methodology to minimize its undesirable effects. This work focus on the c

5. Transformadores de potencia sob dupla excitação CA/CC
The cccurrence of direct component of current and voltage in AC electrical systems is increasing significantly. For the Brazilian electrical network this is associated to the use of modern conversion and transformation techniques, as well as the High Voltage Direct Current schemes. In this way, the study and the performance of euipaments which are designed t

6. A chemically diverse conducting polymer-based "electronic nose".
We describe a method for generating a variety of chemically diverse broadly responsive low-power vapor sensors. The chemical polymerization of pyrrole in the presence of plasticizers has yielded conducting organic polymer films whose resistivities are sensitive to the identity and concentration of various vapors in air. An array of such sensing elements prod
