1. Manganese and Iron Heterodimers and Homodimers in Enzymes : Insights from Density Functional Theory
Sammanfattning : The enzyme ribonucleotide reductase (RNR) catalyzes the reduction of ribonucleotides to deoxyribonucleotides, the building blocks of DNA, and is essential for all organisms. Canonical class I RNR R2 proteins use a diiron cofactor to generate a tyrosyl radical, which is required for catalysis. LÄS MER
2. Signs of Acquiring Bimodal Bilingualism Differently : A Longitudinal Case Study of Mediating a Deaf and a Hearing Twin in a Deaf Family
Sammanfattning : This dissertation based on a case study explores the acquisition and the guidance of Swedish Sign Language and spoken Swedish over a span of seven years. Interactions between a pair of fraternal twins, one deaf and one hearing, and their Deaf[1] family were video-observed within the home setting. LÄS MER
3. Studies of actinides in a superanoxic fjord
Sammanfattning : Water column and sediment profiles of plutonium, americium, thorium and uranium have been obtained in the superanoxic Framvaren fjord, southern Norway. The concentrations of bomb test fallout Pu, Am as well as 'dissolved' Th in the bottom water are the highest recorded in the marine environment. LÄS MER
4. Partial Balayage and Related Concepts in Potential Theory
Sammanfattning : This thesis consists of three papers, all treating various aspects of the operation partial balayage from potential theory.The first paper concerns the equilibrium measure in the setting of two dimensional weighted potential theory, an important measure arising in various mathematical areas, e.g. LÄS MER
5. Optimisation and Application of Intense High-Order Harmonic Pulses
Sammanfattning : The high-order harmonics that are created in the interaction between an intense laser pulse (around 1014 W/cm2) and a gas medium are studied. The high-order harmonic radiation is a relatively new source of coherent radiation in the short wavelength range. LÄS MER
