6. Lipid peroxidation in vivo : Evaluation and application of methods for measurement
Sammanfattning : Lipid peroxidation is thought to be an important factor in the pathophysiology of a number of diseases and in the process of ageing, but its measurement in vivo has been difficult. The aim of this thesis was to evaluate methods for measurement of lipid peroxidation in vivo that are suitable for clinical investigations, and to apply these methods in animal and human studies investigating basal conditions and situations associated with increased lipid peroxidation.

7. Adapting the environmentallysustainable logistics performancemanagement process
Sammanfattning : Process based approaches to environmentally sustainable logistics performancemanagement are lacking within organizations that buy logistics services (buyers) and thatsell logistics services (LSPs), which puts a damper on environmentally sustainablelogistics performance. Organizations understand the potential of environmentallysustainable logistics performance management, but they seems unable to developeffective management processes and accurate environmentally sustainable logisticsmetrics.

8. Friction in metal powder pressing : measurement and characterisation
Sammanfattning : The present work describes different methods for measuring and characterisation of friction in powder compaction process. A new test apparatus has been developed and presented which gives possibility of directly measurement of coefficient of friction during pressing from low to relative high density. LÄS MER
9. Microwave measurement techniques for industrial process monitoring and quality control
Sammanfattning : Process monitoring and quality control by sensor measurements are essential for the automatisation and optimisation of many industrial manufacturing processes. This thesis is concerned with microwave sensing, which is a measurement modality with potential to improve the in-line sensing capabilities in several industries. LÄS MER
10. Geometrical and dimensional Measurement Planning : - a systematic and holistic approach
Sammanfattning : För att försäkra sig om den slutliga kvaliteten på maskinbearbetade komponenter måste tillverkande företag mäta och verifiera de geometriska och dimensionella egenskaperna på komponenter innan dem skickas vidare nedströms till den mer värdeskapande monteringen. Det är idag vanligt att den geometriska och dimensionella mätningen och verifieringen uppstår varje gång då en maskin ställs om, när man startar om eller startar upp en ny produktionslina eller då en produktionsprocess ändras.
