13. Proposição, validação e aplicação de um novo metodo para analise cinematica tridimensional da movimentação da caixa toracica durante a respiração / Proposition, validation and application of a novel method to the 3D kinematical analysis of the rib cage motion during breathing
The present work aimed to propose and validate a novel method to the 3D kinematical analysis of the rib cage motion during breathing and to show an example of application. The kinematical analysis was used to describe the 3D motion of the ribs during breathing. The 3D coordinates of surface markers positioned on the ribs, sternum and vertebrae were used to c

14. Desenvolvimento de sensor virtual empregando redes neurais para medição da composição em uma coluna de destilação. / Soft sensor development using neural networks for inferential composition in a distillation column.
Soft sensors for composition inference models (that are responsible for the quality) of distillation column products, correspond to virtual instruments implemented in software. This software is able to estimate, in real time, the composition of the output products of the column, based on information such as temperature and pressure on several points of the c

17. Radiation-induced errors in memory chips
We have measured probabilities for proton, neutron and pion beams from accelerators to induce temporary or soft errors in a wide range of modern 16 Mb and 64 Mb DRAM memory chips, typical of those used in aircraft electronics. Relations among the cross sections for these particles are deduced. Measurement of alpha particle yields from pions on aluminum, as a

18. Desenvolvimento e aplicação de modelos de transferencia de calibração em espectroscopia no infravermelho proximo de ondas curtas (SW-NIR)
The aim of this work was the development of calibration models using short wave near infrared and the application of calibration transfer techniques in analytical chemistry. In this studies were used three kinds of samples: cachaça, syrup s soft drinks and gasoline. In the first application, have been developed a calibration model to quantifying, in the tem

19. Evolutionary variants of Rous sarcoma virus: large deletion mutants do not result from homologous recombination.
Large deletion (LD) mutants of Prague strain Rous sarcoma virus, subgroup B (PrB), derived by serial undiluted passage through chicken (C/E) cells, were isolated and characterized. Individual LD viruses were initially isolated by cloning in soft agar of infected, chemically transformed quail (QT6) cells. Two regions of the PrB genome were deleted in the form
