  1. 21. The Atmospheric Corrosion of Magnesium Alloys : Influence of Microstructure and Environments

    Författare :Martin Jönsson; Christofer Leygraf; Rajan Ambat; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; metallurgy; Metallurgical manufacturing engineering; Metallurgisk produktionsteknik;

    Sammanfattning : The low density and high specific strength of magnesium alloys have created a great deal of interest in the use of these alloys in the automotive and aerospace industries and in portable electronics. All of these industries deal with applications in which weight is extremely important. LÄS MER

  3. 22. Impact of surface gravity waves on air-sea fluxes and upper-ocean mixing

    Författare :Lichuan Wu; Anna Rutgersson; Erik Sahlée; Ralf Weisse; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Surface gravity waves play a vital role in the air-sea interaction. They can alter the turbulence ofthe bottom atmospheric layer as well as the upper-ocean layer. Accordingly, they can affect themomentum flux, heat fluxes, as well as the upper-ocean mixing. In most numerical models, waveinfluences are not considered or not fully considered. LÄS MER

  4. 23. A meaningful work in a strained context - exploring midwives' work situation and professional role

    Författare :Malin Hansson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Work situation; Work environment; Midwifery; Professional role; Salutogenesis; JD-R;

    Sammanfattning : Midwives report a challenging work situation globally with a work force shortage, which is a large challenge for health-care organisations and can influence midwives’ professional role. The overall aim of this thesis was to explore midwives’ work situation and professional role in relation to models of care, salutogenic factors and job satisfaction and demands. LÄS MER

  5. 24. Theoretical Characterization of Functional Molecular Materials

    Författare :Xiuneng Song; Yi Luo; Mauro Stener; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; first-principles; soft X-ray spectroscopy; endohedral fullerene; fullerene derivatives; self-assembled monolayers; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Sammanfattning : Nowadays, material, energy and information technologies are three pillar industries. The materials that have close relation with our life have also been the foundation for the development of energy and information technologies. LÄS MER

  7. 25. Design, Optimization and Evaluation of a Transonic Aeroelastic Rig

    Författare :Simeng Tian; Andrew R. Martin; Mauricio Gutierrez Salas; Dieter Peitsch; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transonic compressor; Aeroelastic rig; Design; CFD; Unsteady flow; Energiteknik; Energy Technology;

    Sammanfattning : The compressor is one of the most essential components of a modern turbomachinery engine. This component is exposed to vibrations that without proper design can damage structural integrity and lead to failure. LÄS MER
