1. Studies on the enantioselective disposition of amlodipine : A challenge in bioanalysis
Sammanfattning : To study the disposition of the enantiomers of the calcium channel blocker amlodipine in human plasma, an enantioselective high performance liquid chromatographic (HPLC) assay was developed. Several HPLC techniques such as chiral ion-pair forming, chiral derivatisation and direct separation on chiral columns were evaluated. LÄS MER
2. Quantum-Dot Heat Engines
Sammanfattning : This thesis explores the possibilities of using quantum dots (QDs) in nanoscale energy har- vesters converting heat into electrical energy, i.e. heat engines. From a theory perspective, these possibilities have been investigated for almost two decades, and interest in them seem to continuously increase over time. LÄS MER
3. Synthesis and spectroscopic characterization of emerging synthetic cannabinoids and cathinones
Sammanfattning : The application of different analytical techniques is fundamental in forensic drug analysis. In the wake of the occurrence of large numbers of new psychoactive substances possessing similar chemical structures as already known ones, focus has been placed on applied criteria for their univocal identification.

4. Wide-angle scanning wide-band phased array antennas
Sammanfattning : This thesis considers problems related to the design and the analysis of wide-angle scanning phased arrays. The goals of the thesis are the design and analysis of antenna elements suitable for wide-angle scanning array antennas, and the study of scan blindness effects and edge effects for this type of antennas.

5. Family caregiving for persons with heart failure : Perspectives of family caregivers, persons with heart failure and registered nurses
Sammanfattning : Heart failure is a growing public health problem associated with significant morbidity and mortality. Family support positively affects outcomes for the person with heart failure while also leading to caregiver burden. Registered nurses have a key role in supporting and meeting the needs of family caregivers. LÄS MER
