16. Proton trapping in the cellular acidic vacuolar compartment : lysosomal mechanisms in apoptosis/necrosis and iron chelation
Sammanfattning : Under ischemic conditions, a number of cytotoxic metabolic products are formed. Reactive oxygen species are known to be important mediators of progressive ischemic cell injury, and the synergistic damage to cells caused by the combination of such oxygen species and redox-active iron is well appreciated.

17. Investigation on the Influence of Nodularity in Machining of Compacted Graphite Iron (CGI)
Sammanfattning : Stringency of environmental legislation on emission rates and increasing vehicle performance requirements are pushing the automotive and heavy truck industries to find new solutions for their diesel engines. Two potential opportunities to address these challenges involve increased combustion pressure to obtain more efficient combustion or reducing the weight of the engine. LÄS MER
18. Microstructure Evaluation and Wear-Resistant Properties of Ti-alloyed Hypereutectic High Chromium Cast Iron
Sammanfattning : High chromium cast iron (HCCI) is considered as one of the most useful wear resistance materials and their usage are widely spread in industry. The mechanical properties of HCCI mainly depend on type, size, number, morphology of hard carbides and the matrix structure (γ or α). LÄS MER
19. Elastic Properties of Iron Alloys from First-Principles Theory
Sammanfattning : Accurate description of materials requires the most advanced atomic-scale techniques from both experimental and theoretical areas. In spite of numerous available techniques, however, the experimental study of the atomic-scale properties and phenomena even in simple solids is rather difficult. LÄS MER
20. Geophysical tools for prognosis of deformation in hardrock environments
Sammanfattning : Underground mining of the Kiirunavaara iron mineralization is causing large-scale deformation of the hangingwall of the orebody. To understand and possibly predict future deformation, a structural model of the hanging wall and a good understanding of the petrophysical and mechanical properties of the constituent rocks is necessary.
