21. Development of a Methodology for Detecting Coolant Void in Lead-cooled Fast Reactors by Means of Neutron Measurements
Sammanfattning : In a lead-cooled fast reactor (LFR), small bubbles (in the order of one mm or less) may enter the coolant from a leaking steam generator. If such a leakage is undetected the small bubbles may eventually coalesce into a larger bubble in local stagnation zones under the active core. LÄS MER
22. Autonomic nervous system regulation in chronic neck-shoulder pain : Relations to physical activity and perceived stress
Sammanfattning : Neck-shoulder pain (NSP) is a highly prevalent musculoskeletal disorder with unclear causes, and effective prevention and treatment require a further understanding of the underlying mechanisms. Aberrant autonomic nervous system (ANS) regulation is a hypothesized causal element in the development and maintenance of chronic muscle pain. LÄS MER
23. Elucidating Chemical and Electrochemical Side-Reaction Mechanisms in Li-ion Batteries
Sammanfattning : Lithium-ion batteries constitute a leading technology that plays a major role in the transition towards sustainable transportation and power generation. The stability of modern batteries relies on a passivation layer formed on the negative electrode known as the solid electrolyte interphase (SEI). LÄS MER
24. Interaction of water with supplementary cementitious materials: Hydration mechanism, microstructure and moisture transport
Sammanfattning : Supplementary cementitious materials (SCMs) offer a sustainable solution to reduce carbon emissions from the production of cement and concrete. This dissertation explores the impact of SCMs and the related additives on the hydration process of cementitious materials, which can affect their microstructure and transport properties. LÄS MER
25. Immunopeptidomics and autoantigens of interstitial lung diseases
Sammanfattning : We investigate Sarcoidosis and Idiopathic Pulmonary Fibrosis, IPF, to find markers for early fibrosis development. The aetiologies for both diseases are unknown and there is no specific treatment, moreover, there is a lack of diagnostic biomarkers for both diagnose and disease activity. LÄS MER
