Valoración de parámetros ionosféricos con ayuda del método Doppler
(1982)
Se determinó teóricamente el corrimiento vertical Doppler en frecuencia como función de los parámetros de transporte y pérdida correspondientes a una ionosfera nocturna con perfil electrónico parabólico. Partiendo de las ...
Avaliação do volume de fluxo portal em pacientes esquistossomóticos: estudo comparativo entre ressonância magnética e ultrassom Doppler
(Colégio Brasileiro de Radiologia e Diagnóstico por Imagem, 2010-12-01)
OBJECTIVE: To evaluate the agreement between Doppler ultrasonography and magnetic resonance imaging as well as the interobserver reproducibility of both methods in the measurement of portal blood flow in schistosomal ...
Ophthalmic artery Doppler velocimetry in healthy pregnancy
(Elsevier B.V., 2008-03-01)
