  2. 1. Airborne Gravity Gradient, Magnetic and VLF datasets : Case studies of modelling, inversion and interpretation

    Author : Sayyed Mohammad Abtahi; Thomas Kalscheuer; Laust Pedersen; Jochen Kamm; Thorkild Rasmussen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; VLF; gravity gradient; magnetic; airborne; inversion; non-uniqueness;

    Abstract : Northern Sweden is one of the largest hosts for mineral resources in Europe and always has been an interesting area for researchers from various disciplines of Earth sciences. This dissertation is a comprehensive summary of three case study papers on airborne VLF, gravity gradient and magnetic data in the area. READ MORE

  4. 2. Effect of body posture on regional ventilation and perfusion at normal and increased gravity

    Author : Johan Petersson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The prone position is increasingly used to improve arterial oxygenation in intensive care patients with severe acute respiratory failure. This beneficial response is well documented but our understanding of the responsible mechanisms remains incomplete, as does our knowledge of the effect of posture on lung function in healthy individuals.

  5. 3. Effects of gravity and posture on the human lung

    Author : Malin Rohdin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Acceleration; cardiac output; cardiogenic oscillations; closing volume; gas exchange; heart I-ate; human centrifuge; hypergravity; lung diffusing capacity; prone posture; pulmonary-capillary blood volume; rebreathing; single-breath washout; supine;

    Abstract : The presence of the gravitational force at the surface of Earth affects all of the organ systems in landliving creatures. The function of the lung is particularly susceptible to changes in the direction and magnitude of gravity because of the elastic structure of this organ. READ MORE

  6. 4. Body posture and gravity as determinants of lung perfusion and ventilation

    Author : Malin Ax; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Normal lung gas exchange depends on an intimate match between regional ventilation and regional blood flow in the lungs. The beneficial effect of the prone posture in acute respiratory failure is well documented but the mechanisms involved are not completely understood. READ MORE

  7. 5. Uncertainty in Sliding Stability Analyses of Existing Concrete Gravity Dams with Bonded Concrete-Rock Interfaces

    Author : Alexandra Krounis; Stefan Larsson; Fredrik Johansson; Jonny Sjöberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Safety assessment of existing dams becomes more and more important with their increasing age. In addition, new regulations, due to climate changes and changes in knowledge, demand a re-evaluation of the existing dams’ safety. READ MORE
