6. The proteasome as a target for cancer therapy
Sammanfattning : The main objective of this PhD thesis was to evaluate the significance of proteasome genes as prognostic markers for different cancer types and identify specific cancer forms that respond to proteasome inhibition. The proteasome (PSM) plays an important role in maintaining cellular proteostasis and degrades the majority of proteins that require breakdown in the cell. LÄS MER
7. Calibration of Ionization Chambers for Measuring Air Kerma Integrated over Beam Area in Diagnostic Radiology
Sammanfattning : The air kerma area product PKA is an important quantity used by hospital physicists in quality assurance and optimization processes in diagnostic radiology and is recommended by national authorities for setting of diagnostic reference levels. PKA can be measured using a transmission ionization chamber (kerma area product (KAP) meter) mounted on the collimator housing. LÄS MER
8. Computational Studies of Nanotube Growth, Nanoclusters and Cathode Materials for Batteries
Sammanfattning : Density functional theory has been used to investigate cathode materials for rechargeable batteries, carbon nanotube interactions with catalyst particles and transition metal catalyzed hydrogen release in magnesium hydride nanoclusters. An effort has been made to the understand structural and electrochemical properties of lithium iron silicate (Li2FeSiO4) and its manganese-doped analogue. LÄS MER
9. On Performance Analysis of Retransmission Schemes with Fading Channels
Sammanfattning : Future wireless communication systems and services bring increased performance demands, with respect to data-rate(s), reliable communication, (stochastic) real-time guarantees, and more. In this context, not only new communication schemes are needed, but also more capable performance analysis methods are essential. LÄS MER
10. Sub-micron Structures in Laser Ablated YBa2Cu3O7-x Thin Films
Sammanfattning : This thesis treats the epitaxial growth of high-Tc superconductors and other perovskite oxides as well as the patterning of these into sub-micron structures for superconducting electronic devices. A computer controlled laser ablation system, based on a KrF excimer laser (248 nm) to induce ablation, was developed to allow complex thin film growth processes. LÄS MER
