6. Echocardiographic measurements at Takotsubo cardiomyopathy : transient left ventricular dysfunction
Sammanfattning : Takotsubo cardiomyopathy (TTC) is a disease characterized by transient left ventricular (LV) dysfunction and typical wall motion abnormalities in apical parts, without obvious signs of coronary influence. Due to its elusive natural cause and the lack of clarified pathology, further studies are needed. LÄS MER
7. New Bioanalytical Approaches, Magneto Immunoassays and SIRE Technology Based Biosensors
Sammanfattning : This thesis presents two new technologies, SIRE technology based biosensors and magneto immunoassays, which can be used for bioanalytical applications. One of the main problems associated with biosensor technology is the instability of the recognition element since it is of biological origin and thus, has a limited lifetime. LÄS MER
8. Modelling Stiffness and Damping by Use of Fractional Calculus with Application to Railpads
Sammanfattning : When studying the dynamic behaviour of a structure, e g a railway track, it is important for the analyst to model both stiffness and damping accurately. Mathematical models including fractional derivatives have been found to work well for many materials. Such models are linear and causal. LÄS MER
9. Hydrodynamics of very shallow lakes - A study in Lake Krankesjön, Sweden
Sammanfattning : Shallow lakes have great ecological and recreational values. They are also largely affected by humans, mainly through eutrophication, and great efforts are therefore being put into the understanding of these ecosystems. The knowledge is however not complete, and more research is needed to manage these lakes in a sustainable way. LÄS MER
10. Field Measurements and Predictions of River Flow, Sediment Transport and Morphological Changes
Sammanfattning : In an alluvial lowland river, sediment is transported in the form of suspended and bed loads. The fluvial process is the macroscopic view and long-term consequence of sediment movement. LÄS MER
