Por esse motivo, os cirurgiões têm desenvolvido opções táticas para sua correção. A consciência geral de que a retirada do tecido infectado promove uma limpeza radical, o aparecimento de colas biológicas que facilitam o fechamento dos abscessos e o surgimento de novos substitutos valvares melhoraram o resultado do tratamento. OBJETIVO: Demonstrar mais uma opção no tratamento do abscesso aórtico, para casos selecionados, tubo valvulado em posição infra-coronariana. MÉTODOS: Empreendemos a técnica em três pacientes: em dois, empregamos tubo valvulado com prótese mecânica, e em um, com prótese biológica. Dois pacientes necessitaram procedimentos associados com troca da valva mitral em um deles e plástica da valva tricúspide no outro. Todos eram reoperações de próteses em posição aórtica. RESULTADOS: A evolução cirúrgica e pós-operatória imediata foi satisfatória com os três recebendo alta da Unidade de Terapia Intensiva para o quarto. Um dos pacientes evoluiu para óbito durante a internação em razão de co-morbidades graves que já apresentava no pré-operatório, relacionadas a varizes de esôfago e comprometimento hepático. Os outros dois apresentam boa evolução no pós-operatório tardio. CONCLUSÃO: Acreditamos que essa opção seja mais uma alternativa para o tratamento de abscessos com grande comprometimento de estruturas do anel aórtico e da continuidade mitro-aórtica.

Besides of being a measure of regularity, both operators permit to quantify the degree of phase disorder associated with a given gradient field. An application of CEF and GEF to the analysis of the gradient pattern dynamics of a logistic Coupled Map Lattice is presented. Simulations using a Gaussian and random initial condition, provide interesting insights on the the system gradual transition from order/symmetry to disorder/randomness.

We show that such a theory provides an accurate framework for modeling the statistical behavior of the inertial subrange above and below the canopy. For this, we compared the experimental PDFs with the theoretically predicted ones. The data were measured during the wet season of the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA), which was carried out during the months of January-March 1999 in the southwestern part of Amazonia region. Measurements were made simultaneously at different heights in a 60 m micrometeorological tower located in the Biological Reserve of Jaru (10°04'S, 61°56'W), Brazil. The fast response wind speed measurements, sampled at 60 Hz rate, were made using three-dimensional sonic anemometers at the heights of 66 m (above the canopy) and 21 m (below the canopy). The results showed good agreement between experimental data measured above the canopy forest and Tsallis' generalized thermostatistics theory. For below canopy data, the agreement between experimental and theoretical PDFs was fairly good, but some distortion was observed. This is probably due to some peculiar characteristics of turbulent momentum transfer process inside the forest crown. Discussion is presented to explain these results. Conclusions regarding the absence of "universal scaling" in the inertial subrange are also presented in the context of the entropic parameter of Tsallis' theory.

This scheme is based on the Taylor statistical theory of turbulence and on a multifractal approach to the turbulent spectrum of energy. The non-extensive thermodynamics description is used to obtain a multifractal model.
