2. 1. Reading fleck : Questions on philosophy and science

   Author : Eva Hedfors; Sven Ove Hansson; Germund Hesslow; KTH; []
   Keywords : HUMANIORA; HUMANITIES; Ludwik Fleck; Wassermann reaction; Informed consent; Buchenwald studies; Human experimentation; Philosophy subjects; Filosofiämnen;

   Abstract : The present thesis is based on a scientifically-informed, contextualized and historicized reading of Ludwik Fleck. In addition to his monograph, the material studied includes his additional philosophical writings, his internationally-published scientific articles and two, thus-far-unstudied postwar Polish papers related to his Buchenwald experiences.

4. 2. Continuum modelling of work hardening in precipitation hardened alloys

   Author : Philip Croné; Jonas Faleskog; Peter Gudmundson; Norman Fleck; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

   Abstract : This thesis deals with prediction of macroscopic work hardening in a precipitation hardened alloy. The focus is on the particle contribution. A hierarchical modelling approach is adopted where work hardening in a representative material volume on the microscale is homogenized and used to represent the macroscopic hardening. READ MORE

5. 3. The reading of Ludwig Fleck sources and context

   Author : Eva Hedfors; Sven Ove Hansson; KTH; []
   Keywords : HUMANIORA; HUMANITIES; Ludwig Fleck; Wassermann reaction; thought style; Denkstil; Philosophy subjects; Filosofiämnen;

   Abstract : The present thesis is based on a scientifically informed reading of Fleck. In addition to the monograph, the material includes his additional philosophical writings and also his internationally published scientific articles. The sources provided by Fleck have been traced back to the time of their origin. READ MORE

6. 4. Contested Landscapes/Contested Heritage : history and heritage in Sweden and their archaeological implications concerning the interpretation of the Norrlandian past

   Author : David Loeffler; Lars Larsson; Umeå universitet; []
   Keywords : HUMANIORA; HUMANITIES; Archaeology; Scandinavia; Sweden; Norrland; Norrbotten; Västerbotten; Lappland; Ångermanland; Medelpad; Jämtland; Härjedalen; Hälsingland; Gästrikland; history; prehistory; archaeology; philosophy; antiquarianism; heritage; cultural management; identity; Fleck; thought-collective; thought-style; colonialism; colony; periphery; hinterland; kingdom; empire; industrialism; nationalism; romanticism; Sámi; Stone Age; Mesolithic; Neolithic; semi-subterranean; dwelling; typology; C14; shoreline displacement; Arkeologi; Archaeology subjects; Arkeologiämnen; Archaeology; arkeologi;

   Abstract : This case study explores how geo-political power structures influence and/or determine the conception, acceptance and maintenance of what is considered to be valid archaeological knowledge. The nature of this contingency is exemplified through an examination of how the prehistory of Norrland, a region traditionally considered and portrayed as peripheral vis-à-vis the centre-South, was interpreted and presented by Swedish archaeologists during the 20th century.

7. 5. Modelling of compaction of metal powder and damage accum ulation due to fatigue in powder materials

   Author : Joakim Cedergren; Mekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulik; vakuumteknik; vibrationer; akustik; Maskinteknik; hydraulics; Mechanical engineering; friction; FEM; numerical modelling; continuum mechanics; fatigue loading; powder compaction; vacuum technology; vibration and acoustic engineering;

   Abstract : This thesis addresses powder manufactured (P/M) components, with special attention to the compaction process and to the sensitivity to damage accumulation due to fatigue within powder compacted specimens. Three dimensional simulations of the compaction process have been performed, using an explicit dynamic dilatant finite strain finite element code supplemented with the effects from contact friction within the die, modelled by Coulomb friction.
