3. 22. High performing cast aluminium-silicon alloys

   Författare :Martin Riestra; Salem Seifeddine; Ehsan Ghassemali; Jessica Elfsberg; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium cast alloys; melt quality; eutectic modification; grain refinement; microstructure; tensile properties;

   Sammanfattning : The need to produce lighter components due to environmental aspects and the development of electrical vehicles represents an opportunity for cast aluminium-silicon alloys. With high specific strength, good castability, high corrosion resistance and recyclability, these alloys offer an attractive combination of properties as an alternative to steel, cast iron and titanium-based components in certain applications.

4. 23. High Temperature Tribology of Aluminium : Effect of Lubrication and Surface Engineering on Friction and Material Transfer

   Författare :Justine Decrozant-Triquenaux; Jens Hardell; Manel Rodriguez Ripoll; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

   Sammanfattning : Lightweight design for automotive applications has been pursued for several decades and continues to increase. The main driving forces are new and increasingly stringent emission regulations as well as the increasing popularity of electric, or hybrid, vehicles where the increased weight of the batteries need to be compensated by light weight structures.

5. 24. Development of the Lund AMS facility for the detection of Al-26 -- with applications in plant ecology

   Författare :Mikko Faarinen; Kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ion source; injector; plant material; Nuclear physics; Kärnfysik; aluminium; Accelerator mass spectrometry; AMS; Fysicumarkivet A:2003:Faarinen;

   Sammanfattning : Accelerator mass spectrometry (AMS) is a highly sensitive technique to count atoms. The method has a high efficiency, which makes it possible to measure small samples in a relatively short time, usually less than an hour. During the work for this thesis, methods have been developed to detect Al-26 at the Lund AMS facility. LÄS MER

7. 25. Aspects of pertussis, pertussis vaccination and adverse events associated with aluminum adsorbed vaccines

   Författare :Elisabet Bergfors; Göteborgs universitet; []
   Nyckelord :Pertussis; parapertussis; pertussis toxoid; vaccine; vaccination; vaccine trial; adjuvant; aluminium; adsorbed vaccines; adverse event; pruritic nodules; itching nodules; granuloma; sensitisation; hypersensitivity; contact allergy;

   Sammanfattning : The thesis originates in a clinical study of one of the new acellular pertussis vaccines performed in Göteborg in the 1990s. The monocomponent vaccine, pertussis toxoid adsorbed to aluminium hydroxide, had previously been shown to have an efficacy of 71%. LÄS MER
