1. 1. Thermal Stability and Mechanical Properties of Bainitic Steel

   Författare :Adam Ståhlkrantz; Annika Borgenstam; Peter Hedström; Niklas Sarius; Joacim Hagström; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bainite; Austempering; Low alloyed steel; Tempering; Variant pairing; Material characterization; Metallurgical process science; Metallurgisk processvetenskap; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : For material design it is important to understand and establish the relations between the processing of the steel, the resulting microstructure and how that correlate to the properties of the steel. The main focus of this thesis has been to increase this knowledge for low alloy bainitic steels with medium to high carbon content. LÄS MER

4. 3. Anaerobic Digester Fluid Rheology and Process Efficiency : Interactions of Substrate Composition, Trace Element Availability, and Microbial Activity

   Författare :Luka Šafarič; Annika Björn; Sepehr Shakeri Yekta; David Bastviken; David C Stuckey; Linköpings universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Anaerobic digestion; biogas; rheology; trace elements; microbiology; Anaerob rötning; biogas; reologi; spårämnen; mikrobiologi;

   Sammanfattning : As the anthropogenic greenhouse gas emissions continue imposing stress on our environment, it is becoming increasingly important to identify and implement new renewable technologies. Biogas production through anaerobic digestion has a great potential, since it links waste treatment with extraction of renewable energy, enabling circular bio-economies that are vital for a sustainable future.

5. 4. Osteonecrosis. Prognosis and Prevention of the Consequences of Osteonecrosis

   Författare :Jan Juréus; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Abstract Background Osteonecrosis (ON) is defined by the in situ death of bone cells, osteocytes, hematopoietic and fatty marrow precursor cells. Events and risk factors known to be associated with ON are femoral neck fracture, hip dislocation, slipped capital femoral epiphysis in children, humeral head fracture and insufficiency fractures in load-bearing joints.

7. 5. Benthic environmental responses to climatic changes during the late Quaternary: a micropalaeontological and geochemical approach

   Författare :Claire McKay; Kvartärgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; late Quaternary; rapid climate change; Benguela; Mauritania; productivity; upwelling; benthic foraminifera;

   Sammanfattning : There is a limited understanding of how the benthic environment within upwelling regions responded to past rapid climatic changes. Within this thesis, a multiproxy approach is applied to two marine sediment cores from two coastal upwelling sites in the low latitude subtropical Atlantic. LÄS MER
