The stepped channel design have been used since more than 3,000 years. It is understood that low flows behave as successions of free-jets (i.e. nappe flow) while large discharges skim over the pseudo-bottom formed by the step edges. For a range of intermediate flow rates, a transition flow regime takes place. The dominant feature is stagnation on the horizontal step face associated with signifi...
Rubber dams have been used for the past 40 years in river and coastal engineering applications, in Australia and overseas. Despite the increasing interest for rubber dams, little information is available on their hydraulic performances. The overflow characteristics of inflated rubber dams are re-investigated. New analytical calculations provide information on the wall pressure distribution and ...
Abstract The petrochronological records of eclogites in the Scandinavian Caledonides are investigated using EPMA and LA-ICPMS zircon apatite for U–Pb geochronology, combined with major trace element characteristics. Metamorphic from two Lofoten-Vesterålen Complex (Lofoten Archipelago region) collectively yielded a Concordia age 427.8 ± 5.7 Ma an upper intercept 425 30 Ma. Apatites same provided...
In this study, data from garnet-kyanite metapelites in ultrahigh-pressure (UHP) domains of the Western Gneiss Region (WGR), Norway, are presented. U–Pb geochronology and trace element compositions zircon, monazite, apatite, rutile garnet were acquired, pressure–temperature (P–T) conditions calculated using mineral equilibria forward modelling Zr-in-rutile thermometry. Garnet-kyanite gneiss Ulst...
Les condylomes correspondent à des verrues ano-génitales secondaires à une infection par Human Papilloma Virus (HPV). On distingue 3 formes cliniques qui peuvent être associées: les condylomes acuminés, papuleux et plans. Les condylomes acuminés sont les classiques crêtes de coq, tumeurs exophytiques à surface verruqueuse et hyperkératosique de couleur érythémateuse, grisâtre, ou chaire. Les co...
The Barrovian metamorphism of the Lepontine dome is manifested by isograds that cross-cut tectonic nappe contacts, which commonly interpreted as occurred after emplacement. However, pervasive mineral and stretching lineation in amphibolite facies, associated with top-to-foreland shearing, suggests peak conditions are coeval nappe-overthrusting. Here, we combine mapping U-Pb zircon dating to bet...
