1. 1. Liquid phase sintering of W-Ni-Fe composites : liquid penetration, agglomerate separation and tungsten particle growth

   Författare :Anders Eliasson; Hasse Fredriksson; Thomas Gomez-Acebo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Liquid phase sintering; heavy metal; particle composites; tungsten; penetration; agglomerate separation; particle interaction; parabolic flight; sounding rockets; microgravity; Kirkendall effect; Metallurgical process engineering; Metallurgisk processteknik;

   Sammanfattning : The initial stage of liquid phase sintering, involving liquid penetration, agglomerate separation, particle spreading and growth has been investigated in experiments using tungsten heavy alloys. The particle composites used were produced by hot isostatic pressing (HIP) of pure powder mixtures of W-Ni-Fe-(Co). LÄS MER

3. 2. Diskurser om informationssamhället : Analys av några offentliga texter

   Författare :Björn Eliasson; Solveig Hägglund; Per-Anders Forstorp; Karlstads universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Information society; Critical discourse analysis; Information technology; IT; Education; Pedagogik; Education; Pedagogik;

   Sammanfattning : The interest of this thesis is how the information society will be expressed in some public texts. The focus is especially on how such concepts as learning, knowledge, identity and IT as a tool will be constructed discursively. In a social constructionist meaning the future will be created through communication and interaction between people. LÄS MER

5. 4. Numerical Vlasov–Maxwell Modelling of Space Plasma

   Författare :Bengt Eliasson; Bertil Gustafsson; Bo Thidé; Anders Bondeson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Vlasov equation; Maxwell equation; Fourier method; outflow boundary; domain decomposition; Numerical Analysis; Numerisk analys;

   Sammanfattning : The Vlasov equation describes the evolution of the distribution function of particles in phase space (x,v), where the particles interact with long-range forces, but where shortrange "collisional" forces are neglected. A space plasma consists of low-mass electrically charged particles, and therefore the most important long-range forces acting in the plasma are the Lorentz forces created by electromagnetic fields.

7. 5. Tularemia : epidemiological, clinical and diagnostic aspects

   Författare :Henrik Eliasson; Erik Bäck; Anders Sjöstedt; Clas Ahlm; Örebro universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Francisella; tularemia; epidemiology; case-control; diagnosis; PCR; clinical characteristics; immunology; ELISA; lymphocyte stimulation; Medicine; Medicin; Infektionssjukdomar; Infectious Diseases;

   Sammanfattning : Tularemia is a zoonosis caused by the small, fastidious, gram-negative rod Francisella tularensis that appears over almost the entire Northern Hemisphere. In Sweden, tularemia has appeared mainly in restricted areas in northern parts of central Sweden. LÄS MER
