Zinc oxide (ZnO) particles are characterised as a tracer for temperature measurements in turbulent flows, in the context of the thermographic particle image velocimetry technique. Flow measurements are used to compare the temperature precision of ZnO to that obtained using a well-characterised thermographic phosphor, BAM:Eu(2+), under the same conditions.(More)
This paper presents an optical diagnostic technique based on seeded thermographic phosphor particles, which allows the simultaneous two-dimensional measurement of gas temperature, velocity and mixture fraction in turbulent flows. The particle Mie scattering signal is recorded to determine the velocity using a conventional PIV approach and the(More)
The authors report a case of colitis, with anatomo-clinical confrontation, during a treatment with flucytosine. In this fatal colitis, there were neither ulcerations nor pseudo-membranes. The histological data, with significant cytonuclear lesions, were consistent with a toxic-induced disorder of protein synthesis.
Temperature field measurements in liquids are demonstrated using zinc oxide (ZnO) thermographic phosphor particles. The particles are added to the liquid as a tracer. Following laser excitation, the temperature-dependent luminescence emission of the particles is imaged and the temperature is determined using a two-colour intensity ratio method. In this(More)
Simultaneous point measurements of gas velocity and temperature were recently demonstrated using thermographic phosphors as tracer particles. There, continuous wave (CW) excitation was used and the spectral shift of the luminescence was detected with a two-colour intensity ratio method to determine the gas temperature. The conventional laser Doppler(More)
In a case of anterior septal rupture complicating a transeptal myocardial infarction, the diagnosis of IVC is immediately confirmed by bidimensional Doppler with color coding. The abnormal flow and its three components are studied in multiple section planes. Incidences permitting the best visualization of the shunt are the longitudinal sections: left(More)
Non-deployment of an L.G.M. percutaneous vena cava filter is rare. The aim of this paper is to report a new case of this complication. A second filter was inserted between the non-deployed filter and the renal veins to prevent proximal migration of the transvenous interruption device to the pulmonary artery or the right side of the heart, and to guarantee(More)
A 65 old man had a solitary primary pulmonary plasmacytoma. Serum immunoelectrophoresis revealed an immunoglobulin G Lambda M-protein. Screening for multiple myeloma with bone marrow biopsy and skeletal survey were negative. The patient underwent left lower lobectomy associated with resection of mediastinal lymph nodes. Immunoperoxydase staining of the mass(More)
