   Sammanfattning : 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.

4. 3. Gene Expression Profiling of Human Atherosclerosis

   Författare :Sara Hägg; Johan Björkegren; Jesper Tegnér; Josefin Skogsberg; Olle Melander; Linköpings universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : Atherosclerosis is a progressive inflammatory disease that causes lipid accumulation in the arterial wall, leading to the formation of plaques. The clinical manifestations of plaque rupture—stroke and myocardial infarction—are increasing worldwide and pose an enormous economic burden for society. LÄS MER

5. 4. The Precipitation and Deformation Behaviour of Superaustenitic Stainless Steel

   Författare :Stefan Heino; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; precipitation; low cycle fatigue TEM; slip behaviour; superaustenitic stainless steel; EDS; cyclic deformation; HAZ; tungsten; molybdenum;

   Sammanfattning : The present study concerns the precipitation behaviour and the deformation characteristics of a superaustenitic stainless steel with composition Fe-24Cr-22Ni-7.3Mo-0.5N (wt%). Regarding precipitation, also materials with Mo partially replaced by W have been studied. LÄS MER

7. 5. Structure and Stability of Bi1-xSbx and CaAl2-xZnx

   Författare :Karin Söderberg; Osamu Terasaki; Tetsu Ohsuna; Masaki Takata; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Oorganisk kemi;

   Sammanfattning : This thesis is focused on two intermetallic systems Bi1-xSbx and CaAl2-xZnx. Bi and Sb transform into a peculiar incommensurate composite structure under pressure and our intention was to examine the structure and how alloying influences this incommensurate structure. LÄS MER
