13. Modification of a Constitutive Model in the Framework of a Multilaminate Method for Post-Liquefaction Sand
Abstract The estimation of the value and direction of post-liquefaction deformations is one of the most challenging issues in the modelling of liquefaction soil, due to the inherent and induced anisotropy. It is very important in the science of soil-constitutive models to present a simple and comprehensive model for the prediction of fabric anisotropy effect

14. Effect of low or high stress in pre-slaughter handling on pig carcass and meat quality
The objective of this study was to evaluate the consequences of low or high stress during pre-slaughter handling of pigs on their carcass and meat quality. Forty-four animals of a commercial lineage, with an average weight of 107.23±5.23 kg, were used. At lairage the animals were randomly divided into two groups, the least and the most stressed. At slaughte

17. Desenvolvimento de um modelo para construção de mapas genéticos em autopoliploides, com aplicações em cana-de-açúcar / Development of a model to build genetic maps in autopolyploides, with applications in sugarcane
Autopolyploid species are extremely important in agriculture. However, the complex structure of their genomes is not well understood. Despite all advances in genetic mapping of autotetraploids, the vast majority of the models used for autopolyploid species with high ploidy level, such as sugarcane, are approximations of those used in diploid organisms. Thus,

18. Fatores relacionados à retenção de peso no pós-parto
Introduction: Studies show that the pregnancy and postpartum period are two critical moments which increase the exposure to factors which may lead to weight retention and future obesity. Objective: This work aims at identifying the associated factors with the weight retention after pregnancy. Methods: Cohort of 145 women, patients at a private maternity hosp

21. Probabilistic approach for yield analysis of dynamic logic circuits
In deep-submicrometer technologies, process variability challenges the design of high yield integrated circuits. While device critical dimensions and threshold voltage shrink, leakage currents drastically increase, threatening the feasibility of reliable dynamic logic gates. Electrical level statistical characterization of this kind of gates is essential for

22. Método Criptográco Baseado em Autômatos Celulares Bidimensionais para Cifragem de Imagens
This work proposes a new symmetric-key cryptographical model based on von Neumann two-dimensional, heterogeneous and non-additive cellular automata. The encryption process is performed by calculating consecutive pre-images and decryption process by the forward evolution of cellular automata. The proposed model was based on earlier work which used one-dimensi

23. Determination of the association of urine prostate specific antigen levels with anthropometric variables in children aged 5-14 years
PURPOSE: Calculation of PSA is possible in human fluids even if it presents in very low concentrations with the help of hypersensitive immunodiagnostic methods. The periurethral glands represent one of the potential sources of urine prostate specific antigen (uPSA) in both sexes but the purpose of studying PSA levels in children is still unclear in the liter
