1. Corrosion-cavitation-erosion: surface morphology study of a carbon steel in a multiphasic saline bath
ABSTRACT During the production of petroleum and gas, the equipments employed for this activity are subjected to synergetic wear mechanisms, such as corrosion, corrosion-cavitation and corrosion-cavitation-erosion. Laboratory experiments has been performed to reproduce some of these mechanisms, however, sometimes the tests is not capable to recreate the compl

2. Simulação numérica de um sensor de tomografia capacitiva para análise de escoamento bifásico ar-água / Numerical simulation of a capacitance tomography sensor for the buphasic flow air-water analysis
Este trabalho tem como objetivo a simulação numérica de um sensor de tomografia capacitiva elétrica, em função da permissividade elétrica relativa das fases presentes dentro da tubulação, com a finalidade de determinar a melhor geometria do sensor para a geração de imagem de escoamentos numa mistura bifásica ar-água, levando em consideração fl

3. Resolution of multiphasic reactions by the combination of fluorescence total-intensity and anisotropy stopped-flow kinetic experiments.
Multiphasic kinetics are often observed in stopped-flow investigations. To characterize further these kinetic phases, we have developed a methodology whereby fluorescence total intensity and anisotropy stopped-flow data can be combined in a single analysis. Fluorescence total intensity and anisotropy are highly interrelated and contain two very complementary

4. Reaction of the Escherichia coli quinol oxidase cytochrome bo3 with dioxygen: the role of a bound ubiquinone molecule.
We have studied the kinetics of the oxygen reaction of the fully reduced quinol oxidase, cytochrome bo3, using flow-flash and stopped flow techniques. This enzyme belongs to the heme-copper oxidase family but lacks the CuA center of the cytochrome c oxidases. Depending on the isolation procedure, the kinetics are found to be either nearly monophasic and very

5. Kinetics and mechanism of heme-induced refolding of human α-globin
Hemoglobin α and β chains are tightly packed, highly (75%) helical stable molecules. Removal of the heme results in unfolded (30% helical) unstable globin chains that can be refolded to the native conformation by recombination with heme. We have studied the kinetics of heme binding and the ensuing conformational changes by using three stopped-flow techniqu
