21. Approaches to Treatment of Children with Advanced Neuroblastoma
Sammanfattning : Children with advanced neuroblastoma are at high risk for relapse of multidrug resistant disease, despite initial response to intensive multimodality treatment. Neuroblastomas have similarities with immature neuroblasts seen during embryonic development of the sympathetic nervous system (the origin of these tumors). LÄS MER
22. Aberration-Corrected Analytical Electron Microscopy of Transition Metal Nitride and Silicon Nitride Multilayers
Sammanfattning : Two multilayer thin films have been studied: TiN/SiNx and ZrN/SiNx. A double-corrected transmission electron microscope (TEM) was utilized for imaging and spectroscopy. Imaging was carried out in scanning mode (STEM) for all samples. LÄS MER
23. Biokinetics and radiation dosimetry of 14C-labelled triolein, urea, glycocholic acid and xylose in man. Studies related to nuclear medicine “breath tests” using accelerator mass spectrometry
Sammanfattning : 14C-labelled substances have been used in biomedical research and clinical medicine for over 50 years. Physicians and scientists however, often hesitate to use these substances in patients and volunteers because the radiation dosimetry is unclear. LÄS MER
24. Strongly Interacting Electrons in One and Two Dimensions
Sammanfattning : In this thesis I present a theoretical study of three differentstrongly correlated systems: Luttinger liquids, spin-1 chains andthe two-dimensional spin-1/2 Heisenberg model.For every sub-field of our research I summarize the background andprovide further details to the work presented in the appendedpapers.

25. Chemical Mechanical Polishing of Silicon and Silicon Dioxide in Front End Processing
Sammanfattning : Chemical mechanical polishing (CMP) has been used for a long time in the manufacturing of prime silicon wafers for the IC industry. Lately, other substrates, such as silicon-on-insulator has become in use which requires a greater control of the silicon CMP process. LÄS MER
