    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : The small-scale heterogeneities within the Earth's crust and the effect these heterogeneities have on seismic waves have gained increasing interest in the last 15 years. One approach to study seismic wave scattering is through numerical simulations in random media. LÄS MER

  3. 12. Vertical III-V Nanowire Tunnel Field-Effect Transistor

    Författare :Elvedin Memisevic; Nanoelektronik; []
    Nyckelord :Transistor; TFET; Steep slope; Nanowire; III-V materials; HSQ; Vertical; InAs; GaSb; MOSFET;

    Sammanfattning : In this thesis fabrication and optimization of vertical III-V Tunneling Field-Effect transistors was explored. Usage of vertical nanowires, allows for combination of materials with large lattice mismatch in the same nanowire structure. LÄS MER

  4. 13. Effect of antihypertensive treatment at different blood pressure levels

    Författare :Mattias Brunström; Bo Carlberg; Mats Eliasson; Sverre Kjeldsen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood pressure; hypertension; antihypertensive treatment; cardiovascular disease; randomized controlled trial; systematic review; meta-analysis; standardization;

    Sammanfattning : BackgroundHigh blood pressure is associated with an increased risk of cardiovascular disease and premature death. The shape of association between blood pressure and the risk of cardiovascular events is debated. Some researchers suggest that the association is linear or log-linear, whereas others suggest it is J-shaped. LÄS MER

  7. 15. Målstyrning och mellanchefers arbete - hierarki, delaktighet och tillfälligheternas spel : en fallstudie av ett privat företag och en offentlig förvaltning

    Författare :Margaretha Milsta; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; goal steering; middle manager; managerial work; privat firm; public administration; organizational theory.;

    Sammanfattning : This study deals with how goal steering is perceived and experienced at intermediate levels in two organizations, a private firm and a public administration. More specifically, the following three questions are posed: Firstly, how do middle managers perceive and experience goal steering in relation to: (a) what the goals are and what functions they perform; (b) involvement in the formulation and detailed specification of goals in the organization; (c) control of the activity; (d) evaluation of the achievement of goals in terms of the results obtained.
