Dans le cadre de la loi francaise sur la gestion des dechets nucleaires, differents scenarios sont etudies, au moyen du code de calcul COSI, dans le but de proceder a une analyse comparative des differentes options de separation et de transmutation d

Potassium–argon geochronology relies on the absolute quantification of radiogenic 40 Ar ( 40 Ar*) produced by the natural decay of 40 K in K-bearing rocks and minerals. It implies the precise determination of the 40 Ar and 36 Ar contents to account

It is now generally accepted that continental flood basalt (CFB) volcanism bears a strong relationship with continental breakup. The Ethiopian Afar plume has been linked to the opening of the Afar depression. Propagation of the Red Sea and Gulf of Ad

In some applications, luminescence dating needs performing studies above 550 °C and conventional or commercial instruments are not always perfectly adapted to this temperature range. We describe here an automated instrument capable of thermoluminesc

Pulsed-field gel electrophoresis of genomic DNA was carried out on Streptococcus pneumoniae strains to determine its value in the epidemiological survey of pneumococcal infections. Twenty-one clinical strains were chosen to cover a broad range of div

Two new enzyme-linked immunosorbent assays (ELISA), one for the measurement of immunoglobulin G (IgG) (Captia Syphilis-G) and one for the measurement of IgM (Captia Syphilis-M), were evaluated for detecting antibodies to Treponema pallidum. Serum sam

Forty-three lava flows from the Vallone di Rina (Stromboli, Aeolian Islands, Italy) have been investigated for paleomagnetic, geochemical and K–Ar analyses. K–Ar dating shows that two fast building stages occurred at 62±1 and 40±2 ka. The compa

We present an original analytical system for 40Ar/39Ar dating. It makes use of a 180° sector multicollection mass spectrometer equipped with five Faraday cups, which renders peak switching unnecessary during argon isotopic analyses. Compared to the
