1. Kinetics and Thermodynamics of Thermal Inactivation of β-Galactosidase from Aspergillus oryzae
ABSTRACT For optimization of biochemical processes in food and pharmaceutical industries, the evaluation of enzyme inactivation kinetic models is necessary to allow their adequate use. Kinetic studies of thermal inactivation of β-galactosidase from Aspergillus oryzae were conducted in order to critically evaluate mathematical equations presented in the lite

2. Um estudo numérico de otimização estocástica aplicada à estimação de parâmetros de modelos termodinâmicos / A numerical study in stochastic optimization applied to parameter estimation of thermodynamic models
Neste trabalho foi estudado o problema de estimação de parâmetros de modelos termodinâmicos (particularmente, parâmetros de interação binária de regras de mistura de equações de estado cúbicas) utilizando um algoritmo estocástico de otimização global o algoritmo de Luus e Jaakola. O procedimento de otimização foi acoplado a um algoritmo de so

3. Desenvolvimento e validação de um modelo conceitual de aeração em vertedores. / Development and validation of a conceptual model of aeration in spillways.
This study adress prompt aeration in spillways reaching to reduce the cavitation effects on them. References were based on introduction to cavitation machanism and, state of art survey, to leave on not only earlier studies, but also on classical and most recent ones. Based on principles of Physics, such as Mass Conservation and the First Law of Thermodynamic

4. Aspectos numéricos do problema de cálculo de fenômenos de vaporização retrógrada dupla / Numerical aspects of the problem of calculation of phenomenon of double retrograde vaporization
A vaporização retrógrada dupla é um fenômeno termodinâmico onde, ao invés de uma usual curva de ponto de orvalho, o lugar geométrico dos pontos de orvalho apresenta duas abóbadas (ou domos), em temperaturas ligeiramente acima da temperatura crítica do componente mais volátil, e tem uma forma em S, em temperaturas ligeiramente abaixo da referida te

6. Analise e simulação de um sistema de absorção agua-amonia para produção de gelo em escamas
The present work searches for a detailed numerical simulation of an scale ice-maker operating on an absorption cycle using the pair water - ammonia. With such aim a mathematical model was constructed embodying thermodynamics, heat transfer and fluid mechanics phenomena. Such model turns to be an important tool for analysis and development of the system. Firs
