Sammanfattning : The understanding of the strengthening mechanisms is crucialboth in the development of new materials with improvedmechanical properties and in the development of better materialmodels in the simulation of industrial processes. The aim ofthis work has been to study different strengthening mechanismsfrom a fundamental point of view that enables the developmentof a general model for the flow stress. LÄS MER
Sammanfattning : The shear failure mechanisms of flexural reinforced concrete (RC) members is highly complex; its precise details cannot be explained with simple analytical relationships, and are the topic of considerable scientific debate. The studies described and examined the three most used shear theories in the world – the fixed angle truss model (45°TM), the variable angle truss model (VAT), and modified compression field theory (MCFT).

Sammanfattning : The subjective sensitivity to pain differs greatly between individuals and neuroimaging has contributed to the understanding of the cerebral mechanisms involved in pain regulation. The descending pain inhibitory circuitry is a well defined cerebral network that enables regulation of afferent nociceptive information. LÄS MER
Sammanfattning : Mitochondrial disorders constitute a subgroup of the large family of rare monogenic diseases called Inborn Errors of Metabolism (IEM), but defects in mitochondrial activity have also been reported in more common and complex pathologies. In the present thesis, I validate new disease-causing variants and study the underlying molecular defects in three different cases of IEM. LÄS MER
