A presente invenção refere-se a um processo para aprimoramento e recuperação das propriedades eletrónicas não-óhmicas de peças cerâmicas, particularmente cerâmicas vanstoras à base de áxidos metálicos. Este processo aprimora as propriedades eletrónicas não-óhmicas de peças cerâmicas varistoras como obtidas durante a fabricação e recupera tais propriedades em peças cerâmicas que sofreram degradação, tanto física quanto química, durante o uso.
Aplicação de redes NeuroFuzzy ao processamento de peças automotivas por meio de injeção de polímeros

The injection molding of automotive parts is a complex process due to the many non-linear and multivariable phenomena that occur simultaneously. Commercial software applications exist for modeling the parameters of polymer injection but can be prohibitively expensive. It is possible to identify these parameters analytically, but applying classical theories of transport phenomena requires accurate information about the injection machine, product geometry, and process parameters. However, neurofuzzy networks, which achieve a synergy by combining the learning capabilities of an artificial neural network with a fuzzy set's inference mechanism, have shown success in this field. The purpose of this paper was to use a multilayer perceptron artificial neural network and a radial basis function artificial neural network combined with fuzzy sets to produce an inference mechanism that could predict injection mold cycle times. The results confirmed neurofuzzy networks as an effective alternative to solving such problems.

BACKGROUND: The workplace is affected by poor lifestyle habits that can cause alterations in the quality of life (QOL) of the employees. OBJECTIVE: To evaluate the quality of life and the cardiovascular risk factors in employees of a business. Relate the quality of life with the variables of cardiovascular risk, gender and work sector. METHOD: 41 employees were evaluated (30 females and 11 males) aging between 18 and 54 years (mean 27.4 ± 8.9 years). A protocol was used with: personal data, personal background, physical examination (anthropometry) and the WHOQOL-bref questionnaire to evaluate the QOL. Statistical analysis was completed by the Chi-squared test and Sperman’s rank correlation, with a significance of 5%. RESULTS: We found 31(75.6%) sedentary; 16(39.0%) excess weight; 2(4.9%) smokers; 9(22.0%) alcohol consumers and 25(61.0%) family history. We also found 13(31.7%) overweight/low risk and 3(7.3%) obese/moderate risk. The best score on the WHOQOL-bref was on physical health (72.9), and the worst on environment (61.3) and mean score of 69.5 for total QOL. Male employees presented greater scores on all domains, but this association had a non-significant result. There was positive correlation between the physical and psychological domains with the environment and total QOL. CONCLUSION: The employees presented important cardiovascular risk factors like sedentary lifestyle, family history, excess weight and alcohol consumption. The employee’s QOL is considered satisfactory in the perception of health; the best QOL being in the physical domain and the worst in the environment. Change measures are suggested to the company for the cardiovascular risk factors detected.

Theatre plays as Amor nello specchio, written by Giovan Battista Andreini in 1622, and Jean-Jacques Rousseau’s Narcisse (1752), thematize the condition of a spectator submitted to the established morality or inserted in a determinate political structure. Thus, here the myth of Narcissus and the theme of mirroring do not restrict themselves to the realm of individualized psyche.
