1. 26. Unsteady aerodynamic effects on the driving stability of passenger vehicles

   Författare :Adam Brandt; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aerodynamics; wake dynamics; high speed; Vehicle dynamics; driving stability; crosswinds;

   Sammanfattning : The passenger car is a vital part of modern society, giving people the freedom of flexible travel. As technology advances, customers increase their demand for future products. The automotive industry must therefore adapt to society's requirements for energy-efficient travel, where developing low-drag vehicles is key. LÄS MER

3. 27. Particle-fluid interactions under heterogeneous reactions

   Författare :Thamali Rajika Jayawickrama; Kentaro Umeki; Nils Erland L. Haugen; Matthaus Babler; Muhammad Aqib Chishty; Henrik Ström; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stefan flow; drag coefficient; Nusselt number; Sherwood number; particle-fluid flow; reacting flow; Energy Engineering; Energiteknik;

   Sammanfattning : Particle-fluid flows are involved in many natural processes and industrial applications; some examples are drying, solid fuel combustion, gasification, and catalytic cracking. It is vital to understand the phenomena involved in particle-fluid flows in depth for design, predictions and process improvements. LÄS MER

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

   Författare :Malin Hansson; Göteborgs universitet; []
   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. 29. Theoretical Characterization of Functional Molecular Materials
