The energy exchange between internal waves and barotropic currents over inclined bottom topography is studied theoretically and in the framework of the numerical model. The energy balance equation derived for a continuously stratified fluid predicts that energy can either be transferred toward or away from the internal wave depending on the direction of propagation of both the wave and current....

Northwest Africa (NWA) 5790 is the most recently discovered member of the nakhlite group. Its mineralogy differs from the other nakhlites with a high abundance mesostasis (38.1 3.6 vol%) and scarcity of olivine (4.0 2.2 vol%). Furthermore, zoning of augite phenocrysts, and other petrographic and chemical characteristics suggest that NWA 5790 samples the chilled margin of its parent lava flow/si...

Zooplankton in the ocean respond to visual and hydro-mechanical cues such as small-scale shear in turbulent flow. In addition, they form strong aggregations where currents intersect sloping bottoms. Strong and predictable tidal currents over a sill in Knight Inlet, Canada, make it an ideal location to investigate biological behaviour in turbulent cross-isobath flow. We examine acoustic data (38...

The emplacement of the Mesoproterozoic Götemar Pluton into Paleoproterozoic granitoid host rocks of the Transscandinavian Igneous Belt is re-examined by microfabric analysis, including cathodoluminescence microscopy. Field data on the pluton-host rock system are used to strengthen the model. The Götemar Pluton, situated on the Baltic Shield of SE Sweden, is a horizontally zoned tabular structur...

Directional variograms, along the soil profile, can be useful and precise tool that can be used to increase the precision of the assessment of soil pollution. The detail analysis of spatial variability in the soil profile can be also an important part of the standardization of soil magnetometry as a screening method for an assessment of soil pollution related to the dust deposition. The goal of...

Abstract. The strait studied in this paper, “Sundalagið Norður”, is the northern part of a narrow body seawater separating two largest islands Faroe Islands (Faroes). It has shallow sills both ends and considerably deeper waters between. South southern end there an amphidromic region for semidiurnal tides so that tidal range much lower south than north it. resulting forcing generates periodical...

During the sinking process, overflow generates an entrainment phenomenon, accompanied by occurrence, development, and dissipation of vortices. In this paper, particle image velocimetry (PIV) technology is used to measure flow fields sinking, invasion, mixing. order quantitatively analyze mixing processes during overflow, vorticity, turbulence dissipation, Froude number, local Richardson coeffic...

Composite chondrocutaneous grafts were applied to 12 patients in various forms to repair the columellar deficit, to form the nasal tubercle and nostril sill in cleft lip nose patients. Cleft lip-nose deformity patients with alar cartilage hypoplasia, obtuse angulation of the medial and lateral crura and the resulting plica vestibularis, internal nasal valve problems associated with the weakness...

Eruptions at shield volcanoes often occur from radially aligned linear fissures fed by blade-like magma-filled cracks (dykes). The of the 2018 Sierra Negra eruption were scattered on flank volcano. Space-borne radar interferometric data (interferometric synthetic aperture radar) revealed that, unexpectedly, part was a 15 km long, tortuous and flat-lying crack (sill). Here we develop framework t...
