Réalisation d'un dispositif de mesure de la vitesse et de l'atténuation d'ondes ultrasonores dans des liquides sous pression
No full textCet article décrit en détail un dispositif de mesure de la vitesse et du coefficient d'atténuation d'ondes ultrasonores dans des liquides pouvant être portés à des pressions comprises entre 1 et 1 000 bars. La cellule de mesure et les conditions spécifiques de son remplissage (lorsque les échantillons étudiés sont issus de fluides de gisement stockés dans des conditions de pression proches de celles du fond du puits) sont présentées plus particulièrement. Des comparaisons entre les valeurs expérimentales obtenues au moyen de ce dispositif et des valeurs relevées dans la littérature pour quelques corps purs (eau, décane, hexadécane) sont aussi rapportées

No full textToxoplasmosis causes mortality in several avian species, especially passerine birds. Toxoplasmosis was diagnosed in a bar-shouldered dove (Geopelia humeralis) found dead at the zoo of Clères (France). The bird had necrotizing pneumonia and nephritis with intralesional tachyzoites of Toxoplasma gondii. The diagnosis was confirmed by immunostaining with polyclonal rabbit T. gondii antibodies and by transmission electron microscopy. To our knowledge, the bar-shouldered dove is a new host record for T. gondii
