    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; glacier; ice sheet; sea level; runoff; ice; firn; snow; stratigraphy; density; core; radar; thermistor; temperature; preferential water flow; thermal conductivity; water content; Geovetenskap med inriktning mot naturgeografi; Earth Science with specialization in Physical Geography;

    Abstract : Glaciers cover ca 10% of the Earth's land and are found in the high altitudes and latitudes. They are important components of environmental systems due to the multiple feedbacks linking them with the atmosphere, hydrosphere and periglacial landscapes. READ MORE

  2. 2. Numerical Analysis of Evolution Problems in Multiphysics

    Author : Anna Persson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Regularity; generalized finite element; localized orthogonal decomposition; multiscale finite element method; Thermoelasticity; Riccati equations; thermistor; linear elasticity; Joule heating; parabolic equations; regularity; multiscale; finite element method;

    Abstract : In this thesis we study numerical methods for evolution problems in multiphysics. The term multiphysics is commonly used to describe physical phenomena that involve several interacting models. Typically, such problems result in coupled systems of partial differential equations.

    Abstract : Chancroid caused by Haemophilus ducreyi, has been described as a significantly predisposing factor of HIV heterosexual transmission in an endemic region of both diseases. Antibiotic resistances are extensively found in H. ducreyi and many of the resistances are due to the presence of resistance plasmids. READ MORE
