The microsomal fraction from the testes of immature pigs (less than 1 week old) contains 3 beta-hydroxysteroid dehydrogenase-isomerase (3 beta-HSD-isomerase) activities that convert dehydroepiandrosterone (DHA) to 4-androstenedione and 5,16-androstadien-3 beta-ol (andien-beta) to 4,16-androstadien-3-one (dienone). These reactions are necessary for the(More)
This paper presents the Geostationary Fourier Imaging Spectrometer (GeoFIS), a new satellite instrument that has been proposed to monitor tropospheric key pollutants (O 3 , CO) in order to improve the predictive capability of tropospheric chemistry models. The horizontal resolution of GeoFIS is about 15 × 15 km 2 and the temporal resolution is about 60(More)
