Solution of three-dimensional afterbody flow using reduced Navier-Stokes equations

The flow over afterbody geometries was investigated using the reduced Navier-Stokes (RNS) approximation. Both pressure velocity flux-split and composites velocity primitive variable formulations were considered. Pressure or pseudopotential relaxation procedures are combined with sparse matrix or coupled strongly implicit algorithms to form a three-dimensional solver for general non-orthogonal coordinates. Three-dimensional subsonic and transonic viscous/inviscid interacting flows were evaluated. Solutions with and without regions of recirculation were obtained

Mastocitose Mastocytosis

A mastocitose é caracterizada pelo acúmulo patológico e ativação de mastócitos nos tecidos e órgãos. Embora a classificação da mastocitose e seus critérios diagnósticos sejam bem aceitos, há necessidade de estabelecer parâmetros para aplicação de testes diagnósticos, avaliação clínica e respostas aos tratamentos. O objetivo deste trabalho é fazer uma revisão extensa da literatura, oferecendo conhecimento global sobre os mecanismos etiopatológicos e isiopatológicos, dando especial ênfase à diagnose, classificação e tratamento da mastocitose, promovendo a educação médica continuada.<br>Mastocytosis is characterized by pathologic accumulation and activation of mast cells in tissues and organs. Although the classification for mastocytosis and diagnostic criteria are well accepted, there remains a need to define standards for the application of diagnostic tests, clinical evaluations, and responses to treatment. The objective of this article was to make an extensive literature review, providing comprehensive knowledge about the etiopathological and pathophysiological mechanisms, with a special emphasis on diagnosis, classification and treatment of mastocytosis, promoting continued medical education
