Nausées et vomissements chez la femme enceinte [Nausea and vomiting in pregnancy]

Nausea and vomiting in early pregnancy is a common condition at risk to be minimized by women or care providers. If not treated in the early stages, it can evolve to a severe condition with a morbidity risk for the mother and/or the fetus, and expose to public health consequences. Severe forms of nausea and vomiting and hyperemesis gravidarum are a clinical diagnosis with nonspecific manifestations in addition to biologic and metabolic consequences for mother and/or child. Safe and effective treatments can prevent severe consequences if used in an early stage of symptoms

Vestiges of Saxothuringian crust in the central Sudetes, Bohemian massif: Zircon evidence of a recycled subducted slab provenance

Four detrital zircon concentrates from the metasediments and metavolcanics of the Central Sudetes, Bohemian Massif, have been dated using SHRIMP II. The Wyszki paragneiss yielded Precambrian age spectra similar to those characteristic of the Cadomian terranes: (1) Archaean and Palaeoproterozoic zircons are scattered between 2830 and 1867 Ma, and (2) there are abundant Neoproterozoic zircons dated at 803-577 Ma. The estimated maximum sedimentation age for this rock is 566 ± 4 Ma. The Klodzko Fortress pyroclastic metarhyodacite gave an igneous emplacement age of 536 ± 2 Ma. The magmatic precursor to the subvolcanic Gniewoszów metarhyolite was dated at 501 ± 3 Ma. Finally, the Scinawica subvolcanic rhyolite yielded an igneous emplacement age of 338 ± 3 Ma and a large population of inherited zircons dated at: Palaeoproterozoic, Neoproterozoic, Cambro-Ordovician and Late Devonian-early Carboniferous. The dated samples come from two adjacent suspect terranes -the Orlica-Snieznik dome and the Klodzko massif in the Central Sudetes that are characterised by contrasting timing of metamorphism and exhumation. Despite this difference, the results obtained show, in conjunction with earlier data, a similar provenance of the studied units and their common affinity to the Saxo-Thuringian terrane. Since the Central Sudetes are separated from Saxo-Thuringia by a collisional suture, the pre-Variscan rocks must represent the deformed and metamorphosed, allochthonous equivalents to Saxo-Thuringian lithologies. They were probably subducted together with the Saxo-Thuringian passive margin during a Variscan collision and then exhumed within an accretionary wedge in front of Brunia/East Avalonia. The Central Sudetic suspected terranes must have been derived from a dismembered single accretionary complex and were then juxtaposed by strike-slip faults

ESARDA Bulletin No. 53

ESARDA is an association initially formed to advance and harmonize research and development for nuclear safeguards whose scope has in recent year expanded as the number and type of its working groups’ activities below indicates. Esarda is currently composed of about 30 laboratories, private and governmental institutions worldwide. Within Esarda (http://esarda.jrc.ec.europa.eu/), a number working groups have been over the years established and active namely: Techniques and Standards for Destructive Analysis, Techniques and Standards for Non-Destructive Analysis, Containment and Surveillance, Novel Approaches / Novel Technologies, Implementation of Safeguards, Verification Technologies and Methodologies, Training and Knowledge Management, Editorial Committee. ESARDA publishes a Bulletin containing scientific and technical articles related to safeguards and verification (and beyond) as well as news and reports related to the ESARDA activities. This publication appears generally twice a year. In addition, thematic special issues are published as proposed by the ESARDA community. The Bulletin Editorial Board is composed of about 10 experts in the various technical and scientific fields related to safeguards. They are all actively engaged in safeguards R&D or in safeguards implementation and other fields. The Editorial Board decides the contents of the Bulletin, selects the papers to be published and reviews them before publication. All ESARDA editorial activities are carried out at JRC in Ispra. Scientific and technical papers submitted for publication in the peer reviewed section are reviewed by independent authors and by members of the Editorial Committee. The bulletin is currently submitted to Thomson Reuters for evaluation in view of citation. ESARDA Bulletin is published jointly by ESARDA and the Joint Research Centre of the European Commission and distributed free of charge to over 1100 registered members, libraries and institutions worldwide. The bulletin will predominantly contain peer review papers which have been either directly submitted to the journal by the scientific community or selected by the editorial committee and chair sessions of Esarda symposia and or Workshops. The bulletin may also contain reports on the activities of various Esarda working groups, tribune, news etc. where appropriate.JRC.G.II.7-Nuclear securit
