Sammanfattning : The thesis consists of three parts, although each part belongs to a specific subject area in mathematics, they are considered as subfields of the perturbation theory. The main objective of the presented work is the study of the Dirac operator; the first part concerns the treatment of the spurious eigenvalues in the computation of the discrete spectrum. LÄS MER

Sammanfattning : Boreal forests are often strongly nitrogen (N) limited. However, human activities are leading to increased N inputs into these ecosystems, through atmospheric N deposition and forest fertilization. LÄS MER
3. Intrinsic and extrinsic mechanisms for B-cell lymphoma development and progression studied by global gene expression profilingDetta är en avhandling från Stockholm : Karolinska Institutet, Dept of Laboratory Medicine
Sammanfattning : Mantle cell lymphoma (MCL) is a rare hematopoietic malignancy characterized by frequent relapses and poor survival, partly due to minimal residual disease, whereby a subset of malignant cells, harbored in protective niches, survive treatment. In vitro and ex vivo experiments have shown that MCL cells can be rescued from apoptosis through interactions with non- malignant cells such as stromal cells. LÄS MER

Sammanfattning : Orally administered drugs are absorbed in the intestine and generally metabolized in the liver. Therefore, understanding factors determining drug distribution and elimination in these tissues is important. LÄS MER

Sammanfattning : Investigation of nitride fuels and their properties has, for decades, been propelled on the basis of their desirable high metal densities and high thermal conductivities, both of which oer intrinsic advantages to performance, economy, and safety in fast and light water reactor systems. In this time several key obstacles have been identied as impeding the implementation of these fuels for commercial applications; namely chemical interactions with air and steam, the noted diculty in sintering of the material, and the high costs associated with the enrichment of 15N.
