1. Direct and Inverse Scattering of Electromagnetic Waves in Nonlinear Media
Sammanfattning : Models for materials with nonlinear electromagnetic response are examined. Three simple physical causes for nonlinear behavior are presented: electronic polarization, molecular direction and electrostriction. LÄS MER
2. Transient Electromagnetic Waves in Nonlinear Media
Sammanfattning : This thesis is concerned with the propagation of transient electromagnetic waves in nonlinear media. It consists of a General Introduction and five scientific papers. The General Introduction gives a broad overview of nonlinear electromagnetic phenomena. LÄS MER
3. The Inflammatory Bowel Disease Cohort of the Uppsala Region (ICURE) : Epidemiology and Complications
Sammanfattning : The overall aims of this thesis were to investigate the incidence of inflammatory bowel disease in the Uppsala Region of Sweden, to study the clinical course and the impact of the disease with regards to complications.Patients in Uppsala County were included in the study from the 1st of January 2005 and patients in Falun, Eskilstuna and Åland counties from the 1st of January 2007.

4. Managing and Exploring Large Data Sets Generated by Liquid Separation - Mass Spectrometry
Sammanfattning : A trend in natural science and especially in analytical chemistry is the increasing need for analysis of a large number of complex samples with low analyte concentrations. Biological samples (urine, blood, plasma, cerebral spinal fluid, tissue etc. LÄS MER
5. The evolution of ribonucleotide reductases
Sammanfattning : Ribonucleotide reductase (RNR) catalyses the transformation of RNA building blocks, ribonucleotides, to DNA building blocks, deoxyribonucleotides. This is the only extant reaction pathway for de novo synthesis of DNA building blocks and the enzyme is thus necessary for life. RNR is found in all but a few organisms. LÄS MER
