2. 1. Workpiece steels protecting cutting tools from wear : A study of the effects of alloying elements on material transfer and coating damage mechanisms

   Author : Toshiharu Aiso; Staffan Jacobson; Urban Wiklund; Staffan Söderberg; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal cutting; Steel; Cutting tools; Transfer; Coating; Sliding; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

   Abstract : The vision of this thesis is to improve the machinability of workpiece steels. Workpiece material frequently transfers to the cutting tools during machining, and the transfer layers then forming on the tools may give both good and bad effects on machining performance and tool life.

5. 3. Particle emissions from car brakes : The influence of contact conditions on the pad-to-rotor interface

   Author : Mattia Alemani; Ulf Olofsson; Jens Wahlström; Anders Söderberg; Staffan Jacobson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Car brakes emissions; transition temperature; working conditions; environmental design; pin-on-disc; Bilbromsutsläpp; övergångstemperatur; arbetsförhållanden; miljödesign; pinne-på-skiva; Machine Design; Maskinkonstruktion;

   Abstract : Due to their adverse health effects emissions have been regulated for over three decades. Brake wear particulate matter is the most important non-exhaust source, however current knowledge is mainly limited to observational studies. READ MORE

6. 4. Orientation of fibres in suspensions flowing over a solid surface

   Author : Allan Carlsson; Daniel Söderberg; Fredrik Lundell; Staffan Toll; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid mechanics; fibre orientation; shear flow; fibre suspension; papermaking; Fluid mechanics; Strömningsmekanik;

   Abstract : The orientation of fibres suspended in a viscous fluid, flowing over a solid surface, has been studied experimentally. A shear layer was generated, by letting the suspension flow down an inclined plate. READ MORE

7. 5. Pain, fatigue and fear-avoidance beliefs in relation to physical activity and body awareness in persons diagnosed with rheumatoid arthritis

   Author : Helena Lööf; Unn-Britt Johansson; Elisabet Welin Henriksson; Staffan Lindblad; Siv Söderberg; Sophiahemmet Högskola; Karolinska Institutet; Karolinska Institutet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rheumatoid arthritis; Body awareness; Pain; Fatigue; Fear-avoidance beliefs about physical activity; Physical activity; Coping strategies; Cross-cultural adaptation; Concurrent think-aloud interviews; Narrative interviews; Phenomenological; Cross-sectional; Psychometrics; Rheumatoid Arthritis;

   Abstract : Introduction: Pain and fatigue are highly common and a major concern for persons diagnosed with rheumatoid arthritis (RA). Having physical limitations, which have a significant effect on daily life, is also described as a major problem for persons with RA. READ MORE
